Description

[Technical Field]

[0001] The present disclosure relates to a vehicle drive device mounted on a vehicle. [Background technology]

[0002] For example, Patent Document 1 discloses a vehicle equipped with a motor that drives the wheels. The motor in Patent Document 1 is an in-wheel motor built into the wheel hub, and includes a hollow shaft that rotates together with the rotor and a sensor that detects the rotational position of the rotor. The sensor harness is passed through the hollow shaft and extends to the outside of the motor, and then connected to a control board. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7083298 Summary of the Invention [Problem to be solved by the invention]

[0004] The internal temperature and rotational state of a motor are used as part of the information required to control the motor. Since it is desirable to detect the internal temperature of the motor as accurately as possible, a temperature sensor must be installed inside the housing that houses the motor. Installing the temperature sensor inside the housing makes it possible to protect the sensor from external environmental factors such as water and dust, and is believed to help prevent problems such as aging. There is also a demand for installing the resolver used to detect the rotational state of the motor inside the housing to protect it from the external environment.

[0005] If the temperature sensor and resolver are disposed inside the housing, the harnesses extending from the temperature sensor and resolver must be drawn to the outside of the housing. In this regard, in Patent Document 1, the sensor harness is passed through a hollow shaft and extended to the outside, but if it is difficult to adopt such a hollow shaft structure, how to draw the harness to the outside of the housing becomes a problem. In particular, since the temperature sensor and resolver are disposed in locations distant from each other, it may be difficult to achieve a layout in which the temperature sensor harness and the resolver harness are both passed through the hollow shaft of Patent Document 1.

[0006] The present disclosure has been made in consideration of these points, and its purpose is to enable the detection signals of the temperature sensor and resolver to be output to the outside of the housing without adopting a hollow shaft structure and while facilitating the layout of multiple harnesses. [Means for solving the problem]

[0007] To achieve the above object, one aspect of the present disclosure can be based on a vehicle drive device including a motor, a temperature sensor that detects the temperature state of the motor, and a resolver that detects the rotation state of the motor. The vehicle drive device includes a motor housing that accommodates the motor, the temperature sensor, and the resolver, a cover member that covers the motor housing from one side in the motor rotational axis direction, a temperature sensor harness connected to the temperature sensor, and a resolver harness connected to the resolver. The temperature sensor harness and the resolver harness are integrated inside the motor housing. The motor housing has a window through which an aggregate harness that aggregates the temperature sensor harness and the resolver harness passes. An external connector configured to allow connection of an external harness is attached to the cover member so as to pass through the cover member. A tip end of the aggregate harness is connected to the external connector.

[0008] According to this configuration, the temperature sensor harness connected to the temperature sensor and the resolver harness connected to the resolver are integrated inside the motor housing, allowing the temperature sensor harness and the resolver harness to be bundled together. The combined harness then passes through a window in the motor housing and is connected to an external connector attached to the cover member. Because the external harness is connected to the external connector, detection signals from the temperature sensor and the resolver can be input to, for example, a vehicle control unit via the temperature sensor harness, resolver harness, collective harness, and external harness.

[0009] By providing an external connector on the cover member in this way, it is possible to input detection signals from the temperature sensor and resolver to the control unit without employing a hollow shaft structure as in conventional examples. Furthermore, by combining the temperature sensor harness and resolver harness inside the motor housing, only the combined harness can be passed through the window, and the combined harness can also be connected to the connector. Therefore, when a temperature sensor harness and resolver harness are provided, the harness layout is simplified.

[0010] The motor housing may have a housing-side peripheral wall portion, and an opening that is opened and closed by a cover member may be formed in the housing-side peripheral wall portion. A connecting portion for integrating the temperature sensor harness and the resolver harness may be provided inside the motor housing.

[0011] That is, at a manufacturing site for a vehicle drive device, it is conceivable that the motor housing and the cover member are joined first before the temperature sensor harness and the resolver harness are integrated. In this case, the temperature sensor harness and the resolver harness must be integrated after the motor housing and the cover member are joined. In this aspect, an opening is formed in the housing side peripheral wall, so that the temperature sensor harness and the resolver harness can be easily integrated using the connecting portion through the opening. By closing the opening with a cover member after the temperature sensor harness and the resolver harness are integrated, it is possible to prevent water and dust from entering the motor housing.

[0012] The motor housing may have a housing-side vertical wall portion extending radially of the motor rotary shaft, and a housing-side peripheral wall portion protruding from a peripheral edge of the housing-side vertical wall portion in the motor rotary shaft direction and extending circumferentially of the motor rotary shaft. In this case, the window portion may be formed in the housing-side vertical wall portion.

[0013] The resolver may be housed inside the motor housing on the cover member side. The temperature sensor may be housed inside the motor housing on the opposite side from the cover member. The connecting portion may be provided midway through the temperature sensor harness. That is, the resolver and the temperature sensor can be housed in the motor housing spaced apart from each other. In this case, providing a connecting portion midway through the temperature sensor harness allows the temperature sensor harness and the resolver harness to be integrated between the resolver and the temperature sensor. [Effects of the Invention]

[0014] As described above, the detection signals of the temperature sensor and the resolver can be output to the outside of the housing without employing a hollow shaft structure and while facilitating the layout of multiple harnesses. [Brief explanation of the drawings]

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0017] 1 and 2 show a vehicle drive system 1 according to an embodiment of the present invention. The vehicle drive system 1 is mounted on an automobile (not shown) and is a device for driving the drive wheels of the automobile. The automobile may be an electric automobile that runs solely on the power of a motor, or a hybrid automobile that runs using the power of both an internal combustion engine (engine) and a motor. The motor that generates the power to drive the drive wheels is a drive motor. The hybrid automobile may also be a plug-in hybrid that can be charged from an external power source. In this embodiment, a hybrid automobile will be described as the automobile equipped with the vehicle drive system 1. Therefore, as shown in FIG. 3, the automobile equipped with the vehicle drive system 1 also includes a drive battery 100 for supplying power to the motor 2, a control unit 200 for controlling the motor 2, and the like. However, these are well known and therefore will not be described in detail. The control unit 200 includes an inverter circuit and the like.

[0018] The vehicle drive device 1 is mounted, for example, in the engine compartment of an automobile. The engine compartment may be located in the front or rear of the automobile. As shown in each drawing, the front-rear direction and the left-right direction are defined. That is, based on the state in which the device is mounted in the engine compartment of the automobile, the side that is the front of the vehicle will be simply referred to as the front, the side that is the rear of the vehicle will be simply referred to as the rear, the side that is the left side of the vehicle will be simply referred to as the left, and the side that is the right side of the vehicle will be simply referred to as the right. The left-right direction is the vehicle width direction. These definitions of directions are provided merely for the convenience of explaining the embodiments and do not limit the present invention.

[0019] As shown partially in phantom lines in FIG. 2, an engine E is disposed to the right of the vehicle drive device 1 in the engine room. The crankshaft (not shown) of the engine E extends in the left-right direction, and the engine E is a so-called transversely mounted engine. The engine E and the vehicle drive device 1 are aligned side by side in the left-right direction, with the vehicle drive device 1 disposed on the left side of the engine E, and the left portion of the engine E and the right portion of the vehicle drive device 1 connected by a fastening member (not shown). Power output from the crankshaft of the engine E is input to the vehicle drive device 1. Note that the left-right positions may be reversed, and the direction in which the engine E and the vehicle drive device 1 are aligned is not particularly limited. In the case of an electric vehicle, the engine E is not mounted, so the engine room is called a motor room.

[0020] FIG. 3 is a diagram showing a schematic cross section of the vehicle drive device 1. As shown in FIG. 3, the vehicle drive device 1 includes a motor 2, a temperature sensor 3 that detects the temperature state of the motor 2, and a resolver 4 that detects the rotation state of the motor 2. As shown in FIG. 4, the motor 2 has a stator 2a and a rotor 2b (only part of the outer periphery is shown by a virtual line). The axis of the rotation shaft of the motor 2 (motor rotation shaft) is indicated by the symbol B in FIG. 2. The vehicle drive device 1 is mounted on the automobile so that the direction of the motor rotation shaft is the left-right direction. Therefore, the axis of the crankshaft of the engine E and the direction of the motor rotation shaft coincide with each other.

[0021] The temperature sensor 3 is configured with, for example, a thermistor and is disposed in a location close to, for example, the stator 2a of the motor 2 so that it can immediately detect temperature changes in the stator 2a. The temperature sensor 3 constantly outputs a detection signal. The resolver 4 is a rotation angle detection sensor that detects the rotation angle of the rotor 2b. The temperature sensor 3 and the resolver 4 may be conventionally known.

[0022] The vehicle drive device 1 further includes a motor housing 10, a right cover member 20, and a left cover member 30. The motor housing 10, the right cover member 20, and the left cover member 30 are each made of a light alloy such as an aluminum alloy, and are highly rigid members. In this embodiment, the right cover member 20 and the left cover member 30 are located on the right and left sides, respectively, and are therefore named as such, but this is not limiting, and the right cover member 20 may also be called a front cover member, and the left cover member 30 may also be called a rear cover member. The right cover member 20 is a first cover member, and the left cover member 30 is a second cover member.

[0023] The motor housing 10, the right cover member 20, and the left cover member 30 constitute a single case A. The right cover member 20 is located on the right side of the case A and constitutes the right portion of the case A, so the right cover member 20 can also be called the right-side component member. The left cover member 30 is located on the left side of the case A and constitutes the left portion of the case A, so the left cover member 30 can also be called the left-side component member. The motor housing 10 is located between the right cover member 20 and the left cover member 30 and constitutes the left-right intermediate portion of the case A, so the motor housing 10 can also be called the intermediate component member. The motor housing 10 is sandwiched between the right cover member 20 and the left cover member 30 in the left-right direction. The structure of the case A is not limited to the above-described structure and may include additional components.

[0024] The motor housing 10 defines a single accommodation space R (shown in FIG. 3). The motor 2, temperature sensor 3, and resolver 4 are accommodated in this single accommodation space R. The motor housing 10 has a housing-side vertical wall portion 11 and a housing-side peripheral wall portion 12, which are integrally molded. The housing-side vertical wall portion 11 is located at the left end of the motor housing 10 and is an end wall portion extending in the radial direction (up-down and front-rear directions) of the motor rotary shaft. The housing-side peripheral wall portion 12 is an annular wall portion that protrudes rightward along the motor rotary shaft direction from the peripheral edge of the housing-side vertical wall portion 11 and extends continuously in the circumferential direction of the motor rotary shaft. A housing-side fastening portion 12a that protrudes radially outward is formed at the tip (right end) of the housing-side peripheral wall portion 12. The housing-side fastening portion 12a is connected to the right cover member 20 by a fastening member (not shown).

[0025] The motor 2 is located inside the housing-side peripheral wall portion 12. An output combining mechanism (not shown) for combining the output of the engine E and the output of the motor 2 (the rotational force of the rotor 2b) is provided inside the rotor 2b (shown by an imaginary line in FIG. 4). The output combining mechanism is configured so that it can input only the output of the engine E to the subsequent transmission 50 (shown in FIG. 3), input only the output of the motor 2 to the transmission 50, or combine the output of the engine E and the output of the motor 2 in any ratio and input the combined output to the transmission 50. The structure of the output combining mechanism is not particularly limited, and a mechanism used in conventionally known hybrid vehicles can be applied. Conventionally known methods can also be used to control the output combining mechanism.

[0026] A housing-side vertical wall 11, which serves as an end wall, is located at the left end of the motor housing 10, but no end wall is formed at the right end of the motor housing 10, so the motor housing 10 has a structure with an open portion that is open to the right (one side in the direction of the motor rotation axis). Because the accommodation space R is open to the right of the motor housing 10, this open portion of the motor housing 10 is covered from the right by a right cover member 20.

[0027] The right cover member 20 has a right cover-side vertical wall portion 21 and a right cover-side peripheral wall portion 22. The right cover-side vertical wall portion 21 and the right cover-side peripheral wall portion 22 are integrally molded. The right cover-side vertical wall portion 21 is located at the left end of the right cover member 20 and is an end wall portion that extends in the radial direction (up-down and front-rear directions) of the motor rotary shaft so as to cover the open portion of the motor housing 10. The housing-side fastening portion 12a is coupled to the right cover-side vertical wall portion 21 to close the open portion of the motor housing 10.

[0028] The right cover-side peripheral wall portion 22 is an annular wall portion that protrudes in the motor rotation shaft direction from the peripheral edge portion of the right cover-side vertical wall portion 21 and extends continuously in the circumferential direction of the motor rotation shaft. A right cover-side fastening portion 22a that protrudes radially outward is formed at the tip end (right end) of the right cover-side peripheral wall portion 22. The right cover-side fastening portion 22a is connected to the engine E by a fastening member (not shown).

[0029] The left cover member 30 is attached to the side opposite the open portion (left side) of the motor housing 10, and has a left cover-side vertical wall portion 31 and a left cover-side peripheral wall portion 32. The left cover-side vertical wall portion 31 and the left cover-side peripheral wall portion 32 are integrally molded. The left cover-side vertical wall portion 31 is located at the left end of the left cover member 30, and is an end wall portion that extends in the radial direction (up-down and front-rear directions) of the motor rotary shaft.

[0030] The left cover-side peripheral wall 32 is an annular wall that protrudes in the direction of the motor rotation shaft from the peripheral edge of the left cover-side vertical wall 31 and extends continuously in the circumferential direction of the motor rotation shaft. A left cover-side fastening portion 32a that protrudes radially outward is formed at the tip (right end) of the left cover-side peripheral wall 32. The left cover-side fastening portion 32a is connected to the housing-side vertical wall 11 of the motor housing 10 by a fastening member (not shown).

[0031] A transmission 50 is housed inside the left cover side peripheral wall portion 32. The rotational force output from the output combining mechanism housed in the motor housing 10 is input to the transmission 50, where it is slowed down or accelerated before being output. The output of the transmission 50 is transmitted to the drive wheels via a final gear, a drive shaft, etc., which are not shown.

[0032] The temperature sensor 3 and the resolver 4 are disposed at a distance from each other in the direction of the motor rotation axis. The temperature sensor 3 is housed inside the motor housing 10 on the side closer to the right cover vertical wall portion 21, and in this embodiment, is fastened and fixed to the right cover vertical wall portion 21. The resolver 4 is housed inside the motor housing 10 on the side opposite the right cover vertical wall portion 21, and in this embodiment, is fastened and fixed to the housing vertical wall portion 11. As a result, the temperature sensor 3 is housed on the right side of the accommodation space R, and the resolver 4 is housed on the left side of the accommodation space R.

[0033] The vehicle drive system 1 further includes a temperature sensor harness 3a having a base end (one end) connected to the temperature sensor 3, and a resolver harness 4a having a base end (one end) connected to the resolver 4. The temperature sensor harness 3a includes a signal line for transmitting a detection signal of the temperature sensor 3 to a control unit 200 disposed outside the case A. The resolver harness 4a includes a signal line for transmitting a detection signal of the resolver 4 to the control unit 200 disposed outside the case A.

[0034] The temperature sensor harness 3a and the resolver harness 4a are integrated inside the motor housing 10. Specifically, a connecting portion 60 for integrating the temperature sensor harness 3a and the resolver harness 4a is provided inside the motor housing 10. The connecting portion 60 is provided in the middle of the temperature sensor harness 3a. The temperature sensor harness 3a is divided into a base-end harness 3b that is closer to the temperature sensor 3 than the connecting portion 60, and a tip-end harness 3c that is closer to the tip than the connecting portion 60, and the connecting portion 60 is provided between the base-end harness 3b and the tip-end harness 3c.

[0035] The connecting portion 60 has a base-end connector 60a connected to the tip end of the base-end harness 3b and a tip-end connector 60b connected to the base end of the tip-end harness 3c. One of the base-end connector 60a and the tip-end connector 60b is a female connector, and the other is a male connector. By coupling the tip-end connector 60b to the tip-end connector 60b, the base-end harness 3b and the tip-end harness 3c are electrically connected.

[0036] The vehicle drive device 1 further includes a collective harness 61 in which the temperature sensor harness 3a and the resolver harness 4a are gathered together. The collective harness 61 is a harness formed by gathering together the tip-end harness 3c of the temperature sensor harness 3a and the resolver harness 4a.

[0037] A window 11a through which the collective harness 61 passes is formed on the side of the left cover member 30 in the motor housing 10. Specifically, the window 11a is located in the front portion of the housing-side vertical wall portion 11, and is formed so as to penetrate the housing-side vertical wall portion 11 in the thickness direction (left-right direction). The formation of the window 11a makes it possible to route the collective harness 61 (the tip-end side harness 3c and the resolver harness 4a) from the inside of the motor housing 10 to the inside of the left cover member 30. The gap between the inner surface of the window 11a and the collective harness 61 can be sealed with a sealant.

[0038] An external connector 62 configured to be connectable to an external harness 303 is attached to the left cover member 30 so as to penetrate the left cover member 30. That is, a connector mounting hole 32b is formed in the left cover side peripheral wall portion 32, penetrating the left cover side peripheral wall portion 32 in the thickness direction (radial direction). The external connector 62 is fixed to the left cover side peripheral wall portion 32 in a state where it is inserted into the connector mounting hole 32b.

[0039] The tip end (other end) of the collective harness 61 is connected to the external connector 62. The external connector 62 is configured to allow connection of the external harness 303. The side of the external connector 62 to which the external harness 303 is connected faces forward. The side of the external connector 62 to which the external harness 303 is connected may face upward, downward, or rearward.

[0040] The external harness 303 includes signal lines for transmitting the detection signals of the temperature sensor 3 and the resolver 4 to the control unit 200. A connector 304 that is connected to the external connector 62 is provided at an end of the external harness 303. The front portion of the external connector 62 is the portion to which the connector 304 is connected, and therefore the rear portion of the connector 304 is the portion to which the external connector 62 is connected. Either the external connector 62 or the connector 304 may be a female connector or a male connector.

[0041] For example, a socket may be formed in one of the external connector 62 and the connector 304 to make it a female connector, and a plug portion to be inserted into the socket may be formed in the other to make it a male connector. For example, if the socket is formed in the external connector 62, the orientation of the external connector 62 can be determined so that the plug portion faces forward. In this case, the plug portion formed in the connector 304 can be inserted into the socket of the external connector 62 from the front, thereby connecting the connector 304 to the external connector 62. Conversely, if the plug portion is formed in the external connector 62, the orientation of the external connector 62 can be determined so that the plug portion protrudes forward.

[0042] An opening 12c that is opened and closed by a cover member 70 is formed in the housing-side peripheral wall 12 of the motor housing 10. The opening 12c is a through-hole that penetrates the front portion of the housing-side peripheral wall 12 in the thickness direction (front-rear direction). The cover member 70 is disposed on the outside of the housing-side peripheral wall 12 so that the opening 12c can be closed from outside the housing-side peripheral wall 12. The cover member 70 is fastened and fixed to the outer surface of the housing-side peripheral wall 12 by fastening members 72 (shown in FIG. 2, etc.).

[0043] 4 and 6, before the right-side cover member 20 is attached to the motor housing 10, the lid member 70 is not attached to the housing-side peripheral wall portion 12, and the opening 12c is open. In addition, the base-end connector 60a and the tip-end connector 60b are separated, and the tip-end connector 60b is held on the periphery of the opening 12c in the motor housing 10 with the tip-end connector 60b protruding from the opening 12c to the outside of the motor housing 10.

[0044] After the tip connector 60b is held on the periphery of the opening 12c in the motor housing 10, the right cover member 20 is attached to the motor housing 10. The worker can then couple the tip connectors 60b together inside the opening 12c. After coupling the tip connectors 60b together, the connecting portion 60 is inserted into the motor housing 10, and the cover member 70 is fastened and fixed to the outer surface of the housing-side peripheral wall portion 12 with fastening members 72. By providing an opening 12c that can be opened and closed in this manner, the tip connectors 60b can be easily coupled together.

[0045] (Effects of the embodiment) As described above, according to this embodiment, the temperature sensor 3 that detects the temperature state of the motor 2 is provided inside the motor housing 10, so that the temperature state of the motor 2 can be accurately detected. The temperature sensor harness 3a connected to the temperature sensor 3 and the resolver harness 4a connected to the resolver 4 are integrated inside the motor housing 10 by the connecting portion 60, so that the temperature sensor harness 3a and the resolver harness 4a can be bundled together. The combined harness 61 is then passed through the window portion 11a of the motor housing 10 and connected to the external connector 62 attached to the left cover member 30. Because the external connector 62 is connected to the external harness 303, detection signals from the temperature sensor 3 and the resolver 4 can be input to the vehicle control unit 200 via the temperature sensor harness 3a, the resolver harness 4a, the collecting harness 61, and the external harness 303.

[0046] In this way, by providing the external connector 62 on the left cover member 30, it becomes possible to input detection signals from the temperature sensor 3 and the resolver 4 to the control unit 200 without employing a hollow shaft structure as in the conventional example. Furthermore, by gathering the temperature sensor harness 3a and the resolver harness 4a together inside the motor housing 10, it becomes possible for the collective harness 61 to be the only harness that passes through the window portion 11a, and it also becomes possible for the collective harness 61 to be the only harness that connects to the external connector 62. Therefore, when the temperature sensor harness 3a and the resolver harness 4a are provided, the harness layout becomes easier.

[0047] The above-described embodiments are merely examples in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Industrial Applicability]

[0048] As described above, the vehicle drive device according to the present invention can be used in, for example, hybrid vehicles and electric vehicles. [Explanation of symbols]
