Description

Technical Field

[0001] The present invention relates to a saddle-type vehicle equipped with a hybrid drive device driven by an engine and a motor.

Background Art

[0002] There is known a saddle-type vehicle having a hybrid drive device that selects the driving force of an engine and the driving force of a motor according to a running state and transmits them to drive wheels. The saddle-type vehicle is configured to select the driving force of the engine and the driving force of the motor by switching a clutch and transmit them to the drive wheels. The saddle-type vehicle has a control device that controls the motor and the engine, and a battery that supplies electric power to the control device and the motor.

[0003] In the saddle-type vehicle, electric power is supplied from the battery to the motor by a high-voltage line, and electric power is supplied from the battery to the control device and the like by a low-voltage line. In such a saddle-type vehicle, various devices such as the motor, the engine, the battery, the clutch, or the transmission are mounted in the frame, so the routing paths of the high-voltage line and the low-voltage line are limited. Further, it is necessary to route different types of voltage lines so as not to be affected by the heat generation, noise, or movable parts of the engine.

[0004] Patent Document 1 describes a scooter-type electric motorcycle equipped with a hybrid drive system that incorporates an internal combustion engine. In the scooter-type electric motorcycle of Patent Document 1, a pivot shaft is supported horizontally from left to right between the centers of the front half of the frame. A power unit, which integrates an internal combustion engine, a power transmission device (continuously variable transmission), a driving motor, and a rear wheel, is supported on the pivot shaft. The power unit is configured as a unit swing type that rotates vertically at the rear. A battery is located at the front of the frame. A driving motor drive system and a starter motor drive system are located on the left and right sides at the upper rear of the pivot shaft in the frame. A control unit is located at the rearmost part of the frame. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Patent No. 4401286 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The battery, the drive motor drive unit, and the starter motor drive unit are electrically connected by a high-voltage harness. A portion of the high-voltage harness is routed from the drive motor drive unit and the starter motor drive unit, around the front of the pivot shaft, to the drive motor and the starter motor located at the rear of the power unit. This configuration minimizes the movement of the harness due to the vertical rotation of the power unit relative to the frame, thereby improving the durability of the high-voltage harness.

[0007] In a layout in which the internal combustion engine, the power transmission device, the drive motor, and the rear wheels are integrally configured as a power unit and supported on the pivot shaft, the left and right ends of the drive motor may be located further outward than the rear wheels in the left-right direction of the vehicle. Furthermore, in the above layout, space is required for the high-voltage harness to move in accordance with the power unit, which rotates vertically around the pivot shaft as the center of rotation. Therefore, the routing position of the high-voltage harness is restricted. Moreover, in the above vehicle, it is necessary to reduce the vibration of the internal combustion engine transmitted to the drive motor drive unit in order for the drive motor drive unit to exhibit predetermined performance and ensure a predetermined lifespan. In a saddle-type vehicle equipped with such a hybrid drive unit, it is desirable to reduce the vibration of the engine transmitted to the vehicle frame while improving the degree of freedom in routing the voltage lines from the power supply source to the drive motor mounted on the frame.

[0008] The present invention aims to provide a saddle-type vehicle that reduces engine vibrations transmitted to the vehicle frame while improving the degree of freedom in routing voltage lines to the drive motor. [Means for solving the problem]

[0009] The inventors investigated a saddle-type vehicle that reduces engine vibrations transmitted to the vehicle frame while improving the flexibility of routing voltage lines to the drive motor. After diligent investigation, the inventors arrived at the following configuration.

[0010] A saddle-type vehicle according to one embodiment of the present invention comprises a vehicle frame, a drive unit having an engine and a drive motor, vibration-damping links connected to the left and right portions of the vehicle frame in the longitudinal direction and connecting the drive unit to the vehicle frame, a power supply source located in front of the vibration-damping links in the longitudinal direction of the vehicle frame, and a high-voltage line electrically connecting the drive motor, the power supply source, and the drive motor, located behind the vibration-damping links in the longitudinal direction of the vehicle frame, and is driven by the driving force of at least one of the engine and the drive motor. The vibration-damping links have vibration-damping sections that suppress vibrations of the drive unit transmitted to the vehicle frame. The high-voltage line connects the drive motor and the power supply source by passing outside the vibration-damping links in the left-right direction of the vehicle frame.

[0011] In the above configuration, the vibration-damping link is connected to the left and right portions of the vehicle frame, and the vibration suppression unit suppresses vibrations transmitted from the drive unit to the vehicle frame. Therefore, in the saddle-type vehicle, vibrations from the drive unit are less likely to be transmitted to the control device supported by the vehicle frame.

[0012] Furthermore, the high-voltage line supplies current from the power source to the drive motor for driving the drive motor. The high-voltage line is a harness for carrying a current with a voltage higher than, for example, the current used for transmitting control signals. In other words, the high-voltage line has a larger diameter and higher rigidity compared to wires used for transmitting control signals. Therefore, the degree of freedom of bending of the high-voltage line is limited. Moreover, if the drive device is rotatably connected to the vibration-damping link, it is necessary to take into account that the high-voltage line will move as the drive device rotates. Therefore, the routing of the high-voltage line connected to the rotating drive device requires routing space that can follow the rotation of the drive device with bending within an allowable bending range, based on the rigidity of the high-voltage line and the range of motion of the drive device.

[0013] In the saddle-type vehicle of the present invention, a part of the drive unit is positioned inside the vibration-damping link, which is the space between the left and right ends of the vibration-damping link in the left-right direction. Therefore, in the saddle-type vehicle, it is difficult to secure space for routing the high-voltage wires inside the vibration-damping link. On the other hand, in the saddle-type vehicle, it is easier to secure space for routing the high-voltage wires outside the vibration-damping link, which is the space to the left of the left end and to the right of the right end of the vibration-damping link in the left-right direction, compared to the inside of the vibration-damping link. Therefore, when the left and right ends of the drive motor are located outside the rear wheels, the high-voltage wires can be connected to the drive motor via a simple routing route by utilizing the space outside the vibration-damping link as routing space. Thus, the degree of freedom in routing the high-voltage wires to the drive motor is improved. In this way, by connecting the drive unit to the vehicle frame with a vibration-damping link having the vibration-suppressing portion, and routing the high-voltage wires outside the vibration-damping link, it is possible to reduce the vibration of the engine transmitted to the vehicle frame while improving the degree of freedom in routing the high-voltage wires to the drive motor.

[0014] From another perspective, the saddle-type vehicle of the present invention may include the following configuration: The saddle-type vehicle further comprises a control device located in front of the vibration-damping link in the longitudinal direction of the vehicle frame, and a low-voltage line through which a current with a voltage lower than the voltage of the current flowing through the high-voltage line flows. The low-voltage line is located inside the vibration-damping link in the lateral direction of the vehicle frame and connects the control device to the object controlled by the control device.

[0015] In the above-described configuration, the saddle-type vehicle has a high-voltage line that supplies a high-voltage current to the drive motor and the like, and a low-voltage line that supplies a low-voltage current to the control object of the control device. Since the voltage and magnitude of the current supplied differ between the high-voltage line and the low-voltage line, the mechanical properties such as rigidity, thickness, and allowable bending diameter of each voltage line differ. Therefore, due to the difference in mechanical properties, the amount of movement, direction of movement, amount of bending, and trajectory of movement differ between the high-voltage line and the low-voltage line when they move in accordance with the movement of the drive device connected to the vibration-damping link.

[0016] In the saddle-type vehicle of the present invention, the low-voltage wire, which has lower rigidity and thinner diameter than the high-voltage wire, is routed inside the vibration-damping link, where the routing space is smaller than the routing space outside the vibration-damping link. In other words, the routing space between the high-voltage wire and the low-voltage wire is separated by the vibration-damping link. Therefore, in the saddle-type vehicle, when the drive unit is rotatably connected to the vibration-damping link, a part of the vibration-damping link is located between the high-voltage wire and the low-voltage wire, and by routing the high-voltage wire, which has a low degree of freedom of bending, outside the vibration-damping link, contact, friction, or interference between the high-voltage wire and the low-voltage wire can be suppressed. Furthermore, the control signal flowing through the low-voltage wire is susceptible to the influence of noise generated in the high-voltage wire. Therefore, by separating the routing position of the low-voltage wire from the routing position of the high-voltage wire, the influence of the noise on the control signal of the low-voltage wire is suppressed. This improves the degree of freedom in routing high-voltage lines to the drive motor, suppresses the degradation of the control performance of the controlled object due to noise generated in the high-voltage lines, and improves the bending life of each voltage line.

[0017] From another perspective, the saddle-type vehicle of the present invention may include the following configuration: The saddle-type vehicle further includes a radiator located in the longitudinal direction of the vehicle frame, forward of the vibration-damping link, for cooling the drive motor, and a cooling hose for supplying liquid coolant from the radiator to the motor. The radiator is connected to the vehicle frame or the power supply source. The cooling hose connects the radiator and the drive motor, passing outside the vibration-damping link.

[0018] In the above configuration, the drive motor is supplied with a liquid medium from the radiator via the cooling hose. The cooling hose has a larger diameter and higher rigidity than the low-voltage wire. Therefore, the degree of freedom of bending of the cooling hose is limited. Moreover, if the drive unit is rotatably connected to the vibration-damping link, it is necessary to consider that the cooling hose will move as the drive unit rotates. Therefore, the routing of the cooling hose connected to the rotating drive unit requires a routing space that can follow the rotation of the drive unit with bending within an allowable bending range, based on the rigidity of the cooling hose and the range of motion of the drive unit. The cooling hose is routed outside the vibration-damping link, where it is easier to secure a wider routing space compared to inside the vibration-damping link. Therefore, in the saddle-type vehicle of the present invention, the degree of freedom of routing the cooling hose to the drive motor can be improved.

[0019] From another perspective, the saddle-type vehicle of the present invention may include the following configuration: The saddle-type vehicle further has a skid plate located below the vehicle frame. The high-voltage lines pass above the skid plate and below the vehicle frame.

[0020] In the above configuration, the skid plate prevents contact between obstacles or the like from the road surface located below the vehicle body frame and the vehicle body frame and the equipment mounted on the vehicle body frame. Therefore, the high-voltage line routed below the vehicle body frame and above the skid plate does not come into contact with obstacles on the road surface. Thus, the saddle-type vehicle can route the high-voltage line in a space below the vehicle body frame where it is easy to secure a wiring space. Thereby, the degree of freedom in routing the high-voltage line to the drive motor can be improved.

[0021] From another perspective, the saddle-type vehicle of the present invention may include the following configuration. The anti-vibration link connects the lower part of the vehicle body frame and the front part of the drive device.

[0022] In the above configuration, in the saddle-type vehicle, the front part of the drive device is connected to the lower part of the vehicle body frame via the anti-vibration link. When the front part of the drive device is rotatably connected to the anti-vibration link, the drive device rotates about the connection part with the anti-vibration link as the rotation center. The high-voltage line routed to the drive device is bent as the drive device rotates. The amount of bending of the high-voltage line is suppressed by routing it in the vicinity of the connection part. Also, the wiring space for the high-voltage line is smaller as the amount of bending becomes smaller. Therefore, by routing the high-voltage line in the vicinity of the connection part, the amount of bending becomes smaller, and it can be arranged at the lower part of the vehicle body frame.

[0034] [A drive system having an engine and a drive motor] In this specification, a drive device having an engine and a drive motor means a drive device that switches the power transmission path so as to transmit at least the driving force of the motor, of the driving force of the engine and the driving force of the drive motor, to a drive output member. The drive device having an engine and a drive motor includes, for example, an engine, a drive motor, a battery, a drive output member that outputs driving force, and a clutch that switches between a driving force connected state in which the driving force of the engine is transmitted to the drive output member and a driving force disconnected state in which the driving force of the engine is not transmitted to the drive output member. In the driving force disconnected state, the drive device transmits the driving force of the drive motor, which is driven by the power of the battery, to the drive output member, and in the driving force connected state, transmits the driving force of the engine and the driving force of the drive motor, which is driven by the power of the battery, to the drive output member. The drive device having an engine and a drive motor only needs to be configured to transmit the driving force of the engine and the driving force of the drive motor to the drive output member.

[0035] [Vibration Isolation Link] In this specification, a vibration-damping link means a member that supports a drive unit with respect to the body frame of a saddle-type vehicle. The vibration-damping link connects, for example, the left and right portions of the body frame in the longitudinal direction and also connects the drive unit to the body frame. The vibration-damping link also has a vibration-suppressing member that suppresses vibrations transmitted from the drive unit to the body frame. In this embodiment, the vibration-damping link is configured to rotate the drive unit vertically with an axis extending in the left-right direction with respect to the longitudinal direction of the body frame as the center of rotation. The outer side of the vibration-damping link is to the left of the leftmost part of the portion supporting the drive unit and to the right of the rightmost part of the portion supporting the drive unit. The inner side of the vibration-damping link is to the right of the leftmost part of the portion supporting the drive unit and to the left of the rightmost part of the portion supporting the drive unit.

[0036] [High-voltage lines] In this specification, "high-voltage line" means a wire configured to carry current for driving the drive motor. High voltage generally refers to a voltage range of 48V or higher, and in particular, a voltage range of 60V to 800V. High-voltage lines have a larger outer diameter and higher rigidity compared to low-voltage lines.

[0037] [Low-voltage lines] In this specification, low-voltage wires mean wires capable of carrying current to drive control devices, sensors, etc., or capable of transmitting control signals to objects controlled by such control devices. Low voltage generally refers to a voltage range of less than 48V, and in particular, to the voltage ranges of 12V, 24V, and below. Low-voltage wires have a smaller outer diameter and lower rigidity compared to high-voltage wires.

[0038] [Power supply source] In this specification, a power source is a component that supplies power to a drive motor and a control device. The power source includes, for example, a battery and a power generation motor. The power source is electrically connected to the drive motor by a high-voltage line. The power source supplies a high-voltage current to the drive motor. The power source is also electrically connected to the control device by a low-voltage line. The power source supplies a low-voltage current to the control device and the object controlled by the control device.

[0039] [Object to be controlled] In this specification, "controlled object" means an object to which a control device transmits a control signal. The controlled object includes, for example, the fuel injector and various sensors of the engine, various sensors of the drive unit, and a clutch. The controlled object is electrically connected to the control device by low-voltage lines.

[0040] [Saddle-type vehicle] In this specification, a saddle-type vehicle is a vehicle in which the occupant sits on the seat while straddling it. Therefore, a saddle-type vehicle includes not only two-wheeled vehicles but also three-wheeled and four-wheeled vehicles, as long as the occupant sits on the seat while straddling it. [Effects of the Invention]

[0041] According to one embodiment of the present invention, it is possible to realize a saddle-type vehicle that reduces engine vibrations transmitted to the vehicle frame while improving the degree of freedom in routing high-voltage and low-voltage lines to the drive motor.

[0043] The following describes each embodiment with reference to the drawings. In each drawing, the same parts are denoted by the same reference numerals, and the description of those parts will not be repeated. Note that the dimensions of the components in each drawing do not faithfully represent the dimensions of the actual components or the dimensional ratios of each component.

[0044] [Embodiment] <Overall vehicle configuration> Vehicle 1, a saddle-type vehicle according to an embodiment of the present invention, will be described using Figures 1 to 4. Figure 1 is a side view of Vehicle 1 according to an embodiment of the present invention. Figure 2 is a bottom view of Vehicle 1. Figure 3 is an enlarged bottom view of the vibration isolation link 31 of Vehicle 1. Figure 4 is a view taken along the line IV-IV in Figure 3.

[0045] In the following diagrams, arrow F indicates the forward direction of vehicle 1. Arrows RR indicate the rear direction of vehicle 1. Arrow U indicates the upward direction of vehicle 1. Arrow D indicates the downward direction of vehicle 1. Arrow L indicates the left direction of vehicle 1. Arrow R indicates the right direction of vehicle 1. In the following explanation, the up-down direction, left-right direction, and front-back direction refer to the up-down direction, left-right direction, and front-back direction, respectively, as viewed from the perspective of the driver operating vehicle 1.

[0046] As shown in Figures 1 and 2, Vehicle 1 is, for example, a motorcycle. Vehicle 1 has a hybrid drive system 30 that drives the rear wheel 37 by at least the drive motor 36 of the engine 33 and drive motor 36. Vehicle 1 has a body frame 10, a steering shaft 20, a handle 21, a front wheel 22, a drive system 30, a vibration damping link 31, a rear wheel 37, a motor radiator 38, a cooling hose 39, a high-voltage battery 40, a first inverter 41a, a second inverter 41b, a first high-voltage line 42a, a second high-voltage line 42b, a low-voltage battery 43, a low-voltage line 44, a fuel tank 50, a seat 51, a stand 52, a skid plate 53, an engine control device 60, and a vehicle control device 61. Vehicle 1 turns in a tilted position. That is, when turning to the left, Vehicle 1 tilts to the left, and when turning to the right, it tilts to the right.

[0047] The vehicle frame 10 supports various components such as the steering shaft 20, drive unit 30, high-voltage battery 40, fuel tank 50, and seat 51. In this embodiment, the vehicle frame 10 includes a head pipe 11, main frame 12, and seat rail 13.

[0048] The head pipe 11 is located at the front end of the vehicle frame 10. The head pipe 11 rotatably supports the steering shaft 20. The head pipe 11 is located in the center of the vehicle 1 in the left-right direction.

[0049] The main frame 12 is the main component of the vehicle body frame 10. The main frame 12 has a left portion 12a and a right portion 12b that extend rearward from the head pipe 11. The left portion 12a extends from the head pipe 11 to the left and downward from the center of the vehicle 1 in the left-right direction. The right portion 12b extends from the head pipe 11 to the right and downward from the center of the vehicle in the left-right direction. The rear end of the main frame 12 is the lower end of the vehicle body frame 10.

[0050] The seat rail 13 is a component that supports the seat 51. The seat rail 13 is composed of a pair of rails. The pair of rails extend upward and backward from the rear end of the left portion 12a and the rear end of the right portion 12b of the main frame 12, respectively. The rear ends of the pair of rails are connected to each other at the center in the left-right direction.

[0051] The steering shaft 20 transmits the movement of the steering wheel 21 to the front wheels 22. The steering shaft 20 is rotatably supported by the head pipe 11. The steering wheel 21 is connected to the upper end of the steering shaft 20. The front wheels 22 are rotatably supported by the lower end of the steering shaft 20. The front wheels 22 are located below and in front of the head pipe 11.

[0052] The drive unit 30 drives the rear wheels 37, which are the drive wheels. The drive unit 30 also generates electricity. The drive unit 30 includes an engine 33, a crankcase 34, a generator motor 35, and a drive motor 36. The drive unit 30 is connected to the main frame 12 by a vibration-damping link 31. The drive unit 30 is also connected to the seat rail 13 by a suspension (not shown).

[0053] As shown in Figure 3, the vibration-damping link 31 connects the engine 33 and the main frame 12. The vibration-damping link 31 includes a connecting shaft support 31a, a left connection 31b, a right connection 31c, and a vibration-damping bush 31d. The vibration-damping link 31 is located behind the main frame 12 and below the seat rail 13.

[0054] The connecting shaft support portion 31a supports the connecting shaft 32. The connecting shaft support portion 31a is connected by the connecting shaft 32 to the crankcase 34 located at the front end of the drive unit 30. The connecting shaft support portion 31a is configured as a cylindrical shape into which the connecting shaft 32 can be inserted. The connecting shaft support portion 31a is positioned with its axis oriented in the left-right direction. The left-right center of the connecting shaft support portion 31a is located approximately in the left-right center of the vehicle frame 10.

[0055] The left end of the connecting shaft support portion 31a is connected to the left connecting portion 31b. The left connecting portion 31b extends forward and to the left from the left end of the connecting shaft support portion 31a. The right connecting portion 31c is connected to the right end of the connecting shaft support portion 31a. The right connecting portion 31c extends forward and to the right from the right end of the connecting shaft support portion 31a. Therefore, the lateral length of the connecting shaft support portion 31a is smaller than the lateral width between the front end of the left connecting portion 31b and the front end of the right connecting portion 31c. In other words, in the vibration isolation link 31, the lateral width of the rear end is smaller than the lateral width of the front end.

[0056] The front end of the left connection part 31b is bolted to the rear end of the left portion 12a of the main frame 12 via a vibration damping bush 31d, which is a vibration suppression part. The front end of the right connection part 31c is bolted to the rear end of the right portion 12b of the main frame 12 via a vibration damping bush 31d. Therefore, the vibration damping link 31 is located at the lower end of the vehicle body frame 10. In addition, the connecting shaft support part 31a is connected to the front end of the drive unit 30. Thus, the vibration damping link 31 connects the lower end of the vehicle body frame 10 and the front end of the drive unit 30.

[0057] The vibration-damping bush 31d is a bush having vibration-damping rubber between the inner cylinder and the outer cylinder. The vibration-damping bush 31d is, for example, a bush with a cavity formed in the vibration-damping rubber. The vibration-damping bush 31d suppresses the transmission of vibrations between the inner cylinder and the outer cylinder by the vibration-damping rubber. Vibrations transmitted from the drive unit 30 to the vibration-damping link 31 are absorbed or attenuated by the vibration-damping bush 31d. Therefore, the vibration-damping link 31 suppresses vibrations transmitted from the drive unit 30 to the vehicle frame 10.

[0058] As shown in Figures 1 and 2, the engine 33 drives the generator motor 35 and the rear wheels 37. The engine 33 is located behind the vibration damping link 31 and below the seat rail 13. The engine 33 is also located behind the high-voltage battery 40, which will be described later. The engine 33 is located approximately in the center of the vehicle frame 10 in the left-right direction. The engine 33 is arranged so that the piston (not shown) moves in the front-rear direction. That is, the engine 33 is arranged so that the cylinder head (not shown) is located at the front and the crankshaft (not shown) is located at the rear. The engine 33 has a head cover 33a that covers the cylinder head (not shown). The engine 33 also has a crankcase 34. The front end of the crankcase 34 is connected to the connecting shaft support portion 31a of the vibration damping link 31 by a connecting shaft 32. That is, the engine 33 is rotatably supported by the vibration damping link 31 with the connecting shaft 32 as the center of rotation.

[0059] A generator motor 35 is connected to the engine 33. The engine 33 is configured to drive the generator motor 35. The engine 33 is also configured to transmit driving force to the rear wheels 37 via a transmission (not shown). The transmission (not shown) is configured to switch between a state in which the driving force of the engine 33 is transmitted to the rear wheels 37 and a state in which it is not transmitted.

[0060] The crankcase 34 supports a transmission (not shown) and a drive motor 36. The crankcase 34 extends rearward from the right end of the engine 33. The crankcase 34 is located behind the vibration damping link 31 and below the seat rail 13. The crankcase 34 is also located to the right of the center in the left-right direction of the vehicle frame 10. The crankcase 34 is rotatably connected to the vibration damping link 31 by a connecting shaft 32. The crankcase 34 is also connected to the vehicle frame 10 by a suspension (not shown). Thus, the drive unit 30, including the engine 33, a transmission (not shown), a generator motor 35, and a drive motor 36, rotates relative to the vehicle frame 10 with the connecting shaft support 31a as the center of rotation.

[0061] The power generator motor 35 generates electricity to drive the drive motor 36 and the like. The power generator motor 35 is connected to the left end of the engine 33. The power generator motor 35 is located behind the vibration damping link 31 and below the seat rail 13. The power generator motor 35 is located to the left of the center in the left-right direction of the vehicle frame 10. Also, the left end of the power generator motor 35 is located to the left of the left end of the connecting shaft support portion 31a of the vibration damping link 31. The power generator motor 35 is driven by the engine 33. The power generator motor 35 is electrically connected to the first inverter 41a corresponding to the power generator motor 35 by the first high-voltage line 42a.

Power stored in the high-voltage battery 40 is supplied to the drive motor 36 via the second inverter 41b. Therefore, the drive motor 36 drives the rear wheels 37 with power supplied from the high-voltage battery 40 via the second inverter 41b. The drive motor 36 also outputs power generated by the rotational force of the rear wheels 37 to the second inverter 41b. The power output to the second inverter 41b is stored in the high-voltage battery 40.

[0064] The motor radiator 38 cools the cooling medium for cooling the first inverter 41a, the second inverter 41b, the generator motor 35, and the drive motor 36. The motor radiator 38 is fixed, for example, below the front end of the main frame 12. The motor radiator 38 is also located in front of the high-voltage battery 40.

The motor radiator 38 supplies the cooling medium in the order of the first inverter 41a, the second inverter 41b, the generator motor 35, and the drive motor 36.

[0065] The high-voltage battery 40 stores power to be output to the drive motor 36. The high-voltage battery 40 also outputs the stored power to the drive motor 36. The high-voltage battery 40 is, for example, a lithium-ion battery. The high-voltage battery 40 stores power at a voltage of, for example, 48V to 800V. The high-voltage battery 40 is fixed below the main frame 12. The high-voltage battery 40 is located approximately in the center of the main frame 12 in the left-right direction, between the left part 12a and the right part 12b. Furthermore, the high-voltage battery 40 is located in front of the vibration-damping link 31 and the engine 33. The high-voltage battery 40 is also positioned such that a space is created in which the head cover 33a of the engine 33 can be removed and attached when the engine 33 and high-voltage battery 40 are installed on the vehicle frame 10.

[0066] The high-voltage battery 40 is electrically connected to the first inverter 41a and the second inverter 41b. The high-voltage battery 40 is electrically connected to the power generation motor 35 via the first inverter 41a and the first high-voltage line 42a. The high-voltage battery 40 stores the power generated by the power generation motor 35. The high-voltage battery 40 is also electrically connected to the drive motor 36 via the second inverter 41b and the second high-voltage line 42b. The high-voltage battery 40 outputs power to the drive motor 36 via the second inverter 41b.

[0067] The first inverter 41a changes the frequency of the power. It also converts AC power to DC power and DC power to AC power. The first inverter 41a is the inverter corresponding to the power generation motor 35. The first inverter 41a is fixed, for example, to the left side of the high-voltage battery 40. That is, the first inverter 41a is located to the left of the center of the vehicle frame 10. The first inverter 41a is electrically connected to the high-voltage battery 40 and the power generation motor 35 by a first high-voltage line 42a. The first inverter 41a adjusts the frequency of the power generated by the power generation motor 35 and outputs the power to the high-voltage battery 40.

[0068] The second inverter 41b changes the frequency of the power. The second inverter 41b also converts AC power to DC power and DC power to AC power. The second inverter 41b is the inverter corresponding to the drive motor 36. The second inverter 41b is fixed, for example, to the right side of the high-voltage battery 40. That is, the second inverter 41b is located to the right of the center of the vehicle frame 10. The second inverter 41b is electrically connected to the high-voltage battery 40 and the drive motor 36 by a second high-voltage line 42b. The second inverter 41b adjusts the frequency of the power output from the high-voltage battery 40 and outputs it to the drive motor 36. The second inverter 41b adjusts the frequency of the power generated by the drive motor 36 and outputs the power to the high-voltage battery 40.

[0069] The low-voltage battery 43 stores electricity. It also outputs power to various sensors of the power generation motor 35, various sensors of the drive motor 36, the engine control device 60, the vehicle control device 61, etc. The low-voltage battery 43 is, for example, a lithium-ion battery. The low-voltage battery 43 stores electricity at a voltage of, for example, 12V, 24V, or lower. The low-voltage battery 43 is fixed, for example, approximately in the center of the vehicle frame 10 in the left-right direction, to the upper side of the high-voltage battery 40.

[0070] The low-voltage battery 43 is electrically connected to the high-voltage battery 40 via a low-voltage line 44 and a transformer (not shown). The low-voltage battery 43 is supplied with power stepped down from the high-voltage battery 40 by a transformer (not shown). The low-voltage battery 43 is also electrically connected via the low-voltage line 44 to the engine control device 60 and the vehicle control device 61, various sensors of the engine 33 (which is controlled by the engine control device 60), various sensors of the generator motor 35 and various sensors of the drive motor 36 (which are controlled by the vehicle control device 61), etc. The low-voltage battery 43 outputs power to the various sensors of the engine 33, various sensors of the generator motor 35, various sensors of the drive motor 36, and the engine control device 60 and the vehicle control device 61, etc.

[0071] The fuel tank 50 stores fuel for the engine 33. The fuel tank 50 is fixed to the front end of the seat rail 13, which is approximately in the center of the vehicle frame 10 in the front-rear direction. The fuel tank 50 is also located approximately in the center of the vehicle frame 10 in the left-right direction, behind and above the high-voltage battery 40. In other words, the fuel tank 50 is located approximately in the center of the vehicle frame 10 in both the front-rear and left-right directions. The fuel tank 50 is configured to supply fuel to the engine 33.

[0072] The seat 51 is fixed to the seat rail 13. The seat 51 is positioned above the seat rail 13. The seat 51 is positioned on the seat rail 13 so as to cover the fuel tank 50. The seat 51 is configured to be openable and closable relative to the seat rail 13 in order to supply fuel to the fuel tank 50.

[0073] The stand 52 allows the vehicle 1 to stand on its own. The stand 52 is connected to the crankcase 34 via a pivot shaft 52a that extends in the left-right direction. The stand 52 is configured to rotate in the front-rear direction with the pivot shaft 52a as the axis of rotation. The stand 52 has a pair of legs that extend downward to the left and downward to the right from the part that holds the pivot shaft 52a. The stand 52 allows the vehicle 1 to stand on its own in a position with the pair of legs facing downward.

[0074] The skid plate 53 protects the first high-voltage line 42a and the second high-voltage line 42b. The skid plate 53 is, for example, a rectangular plate-shaped member. The skid plate 53 is fixed to the rear end of the main frame 12. The skid plate 53 is located below the vibration damping link 31 and approximately in the center of the vehicle body frame 10 in the left-right direction.

[0075] The skid plate 53 prevents contact between the vehicle frame 10 and the equipment mounted on the vehicle frame 10 and obstacles from the road surface. Therefore, the skid plate 53 prevents contact between the first high-voltage line 42a and the second high-voltage line 42b, which are routed below the vehicle frame 10 and above the skid plate 53, and obstacles on the road surface (see Figure 4). Thus, the vehicle 1 can route the first high-voltage line 42a and the second high-voltage line 42b below the vehicle frame 10, where routing space is easily secured. This improves the degree of freedom in routing the first high-voltage line 42a and the second high-voltage line 42b in the vehicle 1.

[0076] The engine control device 60 controls the engine 33. The engine control device 60 is fixed to the main frame 12. The engine control device 60 is electrically connected to various sensors on the engine 33 by low-voltage lines 44. The engine control device 60 is also electrically connected to the low-voltage battery 43 by low-voltage lines 44.

[0077] The vehicle control device 61 controls the first inverter 41a, the second inverter 41b, various sensors of the power generation motor 35, various sensors of the drive motor 36, and the electrical components of the vehicle 1. The vehicle control device 61 is fixed to the main frame 12. The vehicle control device 61 is electrically connected to the first inverter 41a, the second inverter 41b, various sensors of the power generation motor 35, various sensors of the drive motor 36, and the electrical components by low-voltage lines 44. The vehicle control device 61 is also electrically connected to the low-voltage battery 43 by low-voltage lines 44.

[0078] In this configuration, the vehicle 1 transmits the driving force of at least the drive motor 36, one of the engine 33 and the drive motor 36, to the rear wheels 37. The vehicle 1 also transmits the driving force of the engine 33 to the rear wheels 37 based on the operating state of the drive motor 36 and the state of the high-voltage battery 40. The vehicle 1 charges the high-voltage battery 40 using the generator motor 35 based on the charge state of the high-voltage battery 40. The drive unit 30 of the vehicle 1 rotates relative to the vehicle frame 10 with the connecting shaft support 31a as the center of rotation, depending on the road surface conditions and driving conditions.

[0079] <Routing of high-voltage and low-voltage lines> Next, the routing of the first high-voltage line 42a, the second high-voltage line 42b, and the low-voltage line 44 will be explained using Figures 1 to 4. The first high-voltage line 42a and the second high-voltage line 42b are harnesses for carrying currents with a voltage higher than the current used for transmitting control signals, for example. The low-voltage line 44 is a harness that is less rigid and thinner than the first high-voltage line 42a and the second high-voltage line 42b, for example.

[0080] As shown in Figures 1 and 2, the first high-voltage line 42a, which is a high-voltage line, is routed downward and backward from the first inverter 41a located on the left side of the high-voltage battery 40 toward the vibration-damping link 31. In this embodiment, the first high-voltage line 42a constitutes a voltage system of 48V or higher. The first high-voltage line 42a is routed from the front of the vibration-damping link 31 so as to pass below the left connection part 31b and above the skid plate 53. As shown in Figure 3, the first high-voltage line 42a is connected to the left end of the power generation motor 35 by passing from below the left connection part 31b through the area A1 to the left and outside of the left connection part 31b. At this time, the first high-voltage line 42a is located above the pivot shaft 52a of the stand 52 (see Figure 1). Thus, the first high-voltage wire 42a is routed in the region A1 outside the vibration-damping link 31, which is the space near the connecting shaft 32, which is the rotation center of the drive unit 30, and to the left of the left end of the connecting shaft 32 and to the left of the left connection portion 31b when viewed in the vertical direction. The first high-voltage wire 42a is fixed to the rear end of the main frame 12 and the power generation motor 35 by a clamp member 54.

[0081] As shown in Figures 1 and 2, the second high-voltage line 42b, which is a high-voltage line, is routed downward and backward from the second inverter 41b located on the right side of the high-voltage battery 40 toward the vibration-damping link 31. In this embodiment, the second high-voltage line 42b constitutes a voltage system of 48V or higher. The second high-voltage line 42b is routed from the front of the vibration-damping link 31, passing below the vibration-damping link 31 and above the skid plate 53. As shown in Figure 3, the second high-voltage line 42b is routed from below the right connection part 31c, passing through the area A1 to the right and outside of the right connection part 31c. The second high-voltage line 42b is below the lower side of the crankcase 34 and above the pivot shaft 52a of the stand 52, and passes to the right of the right end of the pivot shaft 52a (see Figure 2) to connect to the left end of the power generation motor 35. Thus, the second high-voltage wire 42b is routed in the region A1 outside the vibration-damping link 31, which is the space near the connecting shaft 32, which is the rotation center of the drive unit 30, and is to the right of the right end of the connecting shaft 32 and to the right of the right connection portion 31c when viewed in the vertical direction. The second high-voltage wire 42b is fixed to the rear end of the main frame 12 and the front and rear ends of the crankcase 34 by clamp members 54.

[0082] As shown in Figures 1 and 2, the low-voltage wire 44 is routed downward and backward from the low-voltage battery 43 located on the upper side of the high-voltage battery 40 toward the vibration-damping link 31. In this embodiment, the low-voltage wire 44 comprises voltage systems of 12V, 24V, and lower voltages. The low-voltage wire 44 is routed above the vibration-damping link 31, passing through region A2 between the left and right ends of the vibration-damping link 31 in the left-right direction when viewed in the vertical direction. Specifically, the low-voltage wire 44 is routed above the connecting shaft support portion 31a of the vibration-damping link 31, passing through a position that overlaps with the connecting shaft support portion 31a when viewed in the vertical direction. Furthermore, the low-voltage wire 44 is connected from above the connecting shaft support portion 31a to various sensors of the power generation motor 35 and various sensors of the drive motor 36, respectively. As shown in Figure 3, the low-voltage line 44 is routed in the inner region A2 of the vibration-damping link 31, which is the space between the left end of the left connection part 31b and the right end of the right connection part 31c, near the connecting shaft 32, which is the rotation center of the drive unit 30.

[0083] As shown in Figure 3, equipment related to the engine 33 is located between the left connection part 31b and the right connection part 31c of the vibration damping link 31. Therefore, in region A2, which is inside the vibration damping link 31, it is difficult to secure space for routing the first high-voltage line 42a and the second high-voltage line 42b, which have high rigidity and limited flexibility in bending. On the other hand, region A1, which is outside the vibration damping link 31, is outside the vehicle frame 10, and it is easier to secure space for routing the first high-voltage line 42a and the second high-voltage line 42b compared to the inside of the vibration damping link 31. Therefore, by using the area outside the vibration damping link 31 as routing space, the first high-voltage line 42a can be connected to the power generation motor 35 and the second high-voltage line 42b can be connected to the drive motor 36 with a simple routing route. Thus, the degree of freedom in routing the first high-voltage line 42a and the second high-voltage line 42b to the drive motor 36 and the power generation motor 35 is improved.

[0084] The first high-voltage wire 42a is routed in the left outer region A1 of the vibration-damping link 31. The second high-voltage wire 42b is routed in the right outer region A1 of the vibration-damping link 31. The low-voltage wire 44 is routed in the inner region A2 of the vibration-damping link 31. In other words, the routing space for the first high-voltage wire 42a, the routing space for the second high-voltage wire 42b, and the routing space for the low-voltage wire 44 are each separated by the vibration-damping link 31. In other words, in vehicle 1, a part of the vibration-damping link 31 is located between the first high-voltage wire 42a, the second high-voltage wire 42b, and the low-voltage wire 44, and by routing the first high-voltage wire 42a and the second high-voltage wire 42b, which have a low degree of freedom of bending, to the outside of the vibration-damping link 31, contact, friction, or interference between the first high-voltage wire 42a, the second high-voltage wire 42b, and the low-voltage wire 44 can be suppressed.

[0085] Furthermore, since the first high-voltage wire 42a and the second high-voltage wire 42b are routed above the pivot shaft 52a, they are located outside the range of motion of the stand 52. Therefore, the first high-voltage wire 42a and the second high-voltage wire 42b do not interfere with the rotating stand 52. Also, when the vehicle 1 tilts due to turning, the stand 52 makes contact before the first high-voltage wire 42a and the second high-voltage wire 42b. Therefore, the stand 52 prevents the first high-voltage wire 42a and the second high-voltage wire 42b from contacting the road surface. Moreover, in the vehicle 1, by routing the second high-voltage wire 42b outside the pivot shaft 52a, the distance between the second high-voltage wire 42b and the rear wheel 37 is increased, thus suppressing interference between the second high-voltage wire 42b and the rear wheel 37.

[0086] Furthermore, by positioning the low-voltage line 44 away from the positioning of the first high-voltage line 42a and the second high-voltage line 42b, the influence of noise generated in the first high-voltage line 42a and the second high-voltage line 42b on the control signal of the low-voltage line 44 is suppressed. This improves the degree of freedom in routing the first high-voltage line 42a and the second high-voltage line 42b for the power generation motor 35 and the drive motor 36, and suppresses the deterioration of the control performance of the controlled object due to noise generated in the first high-voltage line 42a and the second high-voltage line 42b.

[0087] In this way, by routing the first high-voltage wire 42a and the second high-voltage wire 42b outside the vibration-damping link 31 that connects the vehicle body frame 10 and the drive unit 30, the vehicle 1 can reduce vibrations of the engine 33 transmitted to the vehicle body frame 10 while improving the degree of freedom in routing the first high-voltage wire 42a and the second high-voltage wire 42b with respect to the drive motor 36. Furthermore, since the amount of bending of the first high-voltage wire 42a, the second high-voltage wire 42b and the low-voltage wire 44 is suppressed by routing them near the connecting shaft 32, the bending life of the first high-voltage wire 42a, the second high-voltage wire 42b and the low-voltage wire 44 can be improved. Also, the routing space for the first high-voltage wire 42a and the second high-voltage wire 42b becomes smaller as the amount of bending decreases. Therefore, the first high-voltage wire 42a and the second high-voltage wire 42b can be positioned near the vibration-damping link 31 located at the bottom of the vehicle body frame 10.

[0088] <Cooling hose routing> Next, the routing of the cooling hose 39 will be explained using Figures 1 to 3.

[0089] As shown in Figures 1 and 2, the cooling hose 39 is routed downward and rearward from the motor radiator 38 located in front of the high-voltage battery 40 toward the vibration-damping link 31. The cooling hose 39 is routed from in front of the vibration-damping link 31, passing below the right connection portion 31c of the vibration-damping link 31 and above the skid plate 53. Furthermore, the cooling hose 39 is routed from below the right connection portion 31c, passing to the right of the right connection portion 31c. The cooling hose 39 is routed below the lower side surface of the crankcase 34 and above the pivot shaft 52a of the stand 52, passing to the right of the right end of the pivot shaft 52a, and connects to the left end of the generator motor 35. Thus, as shown in Figure 3, the cooling hose 39 is routed in the area A1 outside the vibration-damping link 31, which is the space near the connecting shaft 32, which is the rotation center of the drive unit 30, to the right of the right end of the connecting shaft 32, and to the right and outward of the right connection portion 31c.

[0090] The cooling hose 39 has a larger diameter and higher rigidity compared to the low-voltage wire 44. Therefore, the degree of freedom of bending of the cooling hose 39 is limited. The cooling hose 39 is routed outside the vibration-damping link 31, which allows for a wider routing space compared to inside the vibration-damping link 31. Therefore, in vehicle 1, the degree of freedom of routing the cooling hose 39 relative to the drive motor 36 can be improved.

[0091] <Other Embodiments> In the embodiment described above, the first inverter 41a is fixed to the left side of the high-voltage battery 40. The second inverter 41b is fixed to the right side of the high-voltage battery 40. However, both the first and second inverters may be fixed to either the left or right side of the high-voltage battery.

[0092] In the above-described embodiment, the first inverter 41a is fixed to the left side of the high-voltage battery 40. The second inverter 41b is fixed to the right side of the high-voltage battery 40. However, the vehicle may have both the first and second inverters fixed to either the left or right side of the high-voltage battery, with the engine control device and vehicle control device installed on the other side. By arranging the first and second inverters separately from the engine control device and vehicle control device in this way, the influence of noise generated from the first and second high-voltage lines connected to the first and second inverters can be suppressed.

[0093] In the above embodiment, the first inverter 41a is fixed to the left side of the high-voltage battery 40. The second inverter 41b is fixed to the right side of the high-voltage battery 40. However, the first and second inverters may be fixed to any side of the high-voltage battery. The first and second inverters may also be fixed to the vehicle frame.

[0095] In the embodiment described above, the low-voltage battery 43 is fixed to the upper side of the high-voltage battery 40. However, the low-voltage battery may be fixed to any side of the high-voltage battery. Alternatively, the low-voltage battery may be fixed to the vehicle frame.

[0096] In the embodiment described above, the engine control device 60 and the vehicle control device 61 are fixed to the main frame 12. However, at least one of the engine control device and the vehicle control device may be fixed to the vehicle body frame.

[0097] In the above-described embodiment, the motor radiator 38 is fixed to the vehicle frame 10. However, the motor radiator may also be fixed to the high-voltage battery.

[0098] In the above-described embodiment, the power generation motor 35 is located on the left side of the vehicle frame 10. The drive motor 36 is located on the right side of the vehicle frame 10. However, both the power generation motor and the drive motor may be located on either the left or right side of the vehicle frame. Alternatively, the vehicle may have the power generation motor located on the right side of the vehicle frame and the drive motor located on the left side of the vehicle frame.

[0099] In the above-described embodiment, the vibration-damping link 31 is connected to the vehicle frame 10 via a vibration-damping bush 31d, which is a vibration-suppressing part. However, the vibration-suppressing member can be any member that can suppress vibrations from the drive unit. The vibration-suppressing part may be, for example, a liquid bush, a spring, a hydraulic damper, an air damper, a resin material, etc.
