Description

Technical Field

[0001] The invention relates to a motor vehicle, in particular a motorcycle, according to the preamble of patent claim 1. Background Art

[0002] From DE 20 2016 004 869 U1 a motorcycle is known which has a motor and an electronic sound generating system which comprises at least one loudspeaker for influencing and / or supporting the sound of the motor and / or external noise. Summary of the invention

[0003] The object of the present invention is to provide a motor vehicle, in particular a motorcycle, which allows particularly low-emission operation and at the same time particularly advantageous aerodynamics of the motor vehicle.

[0004] According to the invention, this object is achieved by a locomotive having the features of patent claim 1. Advantageous embodiments of the invention are the subject matter of the dependent claims.

[0005] The present invention relates to a locomotive. The locomotive is preferably configured as a motorcycle. The locomotive, also referred to as a vehicle, is, for example, a monorail motor vehicle, in particular a monorail motorcycle, which has exactly two wheels, also referred to as wheels, arranged in a row and thus in a row in the longitudinal direction of the vehicle of the locomotive. The locomotive according to the present invention can also be understood as a locomotive, in particular a motorcycle, having a sidecar and therefore having exactly three wheels, also referred to as wheels. It is therefore conceivable that the locomotive has exactly three wheels. The respective wheels are ground contact elements, via which the locomotive can be supported or supported downwardly at the ground in the vehicle height direction of the locomotive. If the locomotive travels along the ground, while the locomotive is supported downwardly at the ground in the vehicle height direction of the locomotive via the ground contact elements, the wheels roll directly at the ground in particular. One of the wheels of the locomotive is the rear wheel of the locomotive, and the other of the wheels is the front wheel of the locomotive, wherein the rear wheel is arranged behind the front wheel in the longitudinal direction of the vehicle of the locomotive. Thus, if the motor vehicle has, for example, exactly two wheels, then exactly one of the two wheels is the mentioned front wheel, and the other of the exactly two wheels is the mentioned rear wheel. If the motor vehicle has, for example, exactly three wheels, then it is conceivable that exactly one of the three wheels is the front wheel, and exactly two of the three wheels are rear wheels, which are arranged in the longitudinal direction of the vehicle behind exactly one front wheel. Thus, for example, the motor vehicle is a three-wheeled vehicle, in particular a two-track vehicle, in particular a three-wheeled motorcycle. If the motor vehicle has, for example, exactly three wheels, then it is further conceivable that exactly one of the three wheels is the rear wheel, and exactly two of the three wheels are the front wheels, which are arranged in the longitudinal direction of the vehicle in front of exactly one rear wheel. Thus, for example, the motor vehicle is a three-wheeled vehicle, in particular a two-track vehicle. The motor vehicle has an internal combustion engine, also referred to as a combustion motor or motor, by means of which the motor vehicle can be driven. For example, the internal combustion engine can drive at least one or exactly one of the wheels, in particular the rear wheel, so that the motor vehicle can be driven and thus travel along the ground. It is further conceivable that the internal combustion engine can drive exactly two of the wheels, in particular exactly two rear wheels. The locomotive also has an exhaust duct, also referred to as an exhaust system, through which the exhaust gas of the internal combustion engine can flow. A particle filter is arranged in the exhaust duct through which the exhaust gas can flow, with the aid of which particles that may be contained in the exhaust gas can be filtered out of the exhaust gas. In particular, the internal combustion engine is designed as a gasoline engine, so that the particle filter can be designed as a gasoline particle filter (OPF). By using a particle filter, a particularly low-emission operation of the locomotive can be achieved, because particles that may be contained in the exhaust gas, in particular soot particles, can be filtered out of the exhaust gas with the help of the particle filter.

[0006] Furthermore, in order to achieve particularly advantageous aerodynamics and thus particularly efficient operation of the locomotive, it is provided according to the invention that the particle filter is arranged at least partially, in particular at least predominantly and therefore at least more than half or completely between the internal combustion engine and the rear wheel, as viewed in the longitudinal direction of the vehicle of the locomotive. This can be understood in particular as follows: the internal combustion engine has a motor body, by which at least one or more combustion chambers of the internal combustion engine are at least partially, in particular directly, limited. For example, the internal combustion engine is configured as a reciprocating piston motor, so that the motor body is preferably a cylinder block. The cylinder block has at least one or more cylinders, wherein the corresponding cylinder at least partially, in particular directly, limits the corresponding combustion chamber. For example, the internal combustion engine has at least one cylinder head, which is configured separately from the motor body and is connected to the motor body. In this case, for example, the cylinder head for at least one combustion chamber forms a combustion chamber top, by which at least one combustion chamber is partially, in particular directly limited. In this case, the particle filter is arranged at least partially, in particular at least mainly and therefore at least more than half or completely, between the motor body and the rear wheel in the longitudinal direction of the vehicle, so that the particle filter is connected to the internal combustion engine, in particular the motor body, in the longitudinal direction of the vehicle, and so that the rear wheel is connected to the particle filter in the longitudinal direction of the vehicle. In particular, it is provided that the entire motor body, in particular the entire internal combustion engine, is connected to the particle filter forward in the longitudinal direction of the vehicle. In addition, it is conceivable that the entire rear wheel is connected to the particle filter in the longitudinal direction of the vehicle. The present invention is based in particular on the following recognition: On the one hand, the use of a particle filter enables particularly low-emission operation of a power locomotive. On the other hand, the positioning of the particle filter in or at the power locomotive is problematic because the particle filter has a large volume and therefore high installation space requirements, especially due to its function. It is desirable here that the particle filter is arranged in such a way that a power locomotive equipped with a particle filter has particularly good aerodynamics and can therefore be driven particularly efficiently and therefore with low fuel consumption. It has been found that an arrangement of the particle filter between the internal combustion engine, in particular the motor body, and the rear wheels, viewed in the longitudinal direction of the vehicle, enables particularly advantageous aerodynamics of the motor vehicle.

[0007] In order to be able to achieve particularly advantageous aerodynamics for the locomotive, it is provided in one embodiment of the present invention that the particle filter is arranged between the internal combustion engine, in particular the motor body, and the rear wheel at least partially, in particular at least mainly, and therefore at least more than half or completely, as viewed in the longitudinal direction of the vehicle, so that the particle filter is at least partially, in particular at least mainly, and therefore at least more than half or completely overlapped by the internal combustion engine, in particular by the motor body, in the longitudinal direction of the vehicle forward and at least partially, in particular at least mainly, and therefore at least more than half or completely overlapped by the rear wheel in the longitudinal direction of the vehicle rearward.

[0008] In another embodiment of the invention, the motor vehicle has a frame, on which a rear wheel swing arm is pivotably supported and thus held, in particular in such a way that the rear wheel swing arm, also referred to as swing arm or rear wheel fork, can be pivoted relative to the frame about a pivot axis extending in the vehicle transverse direction of the motor vehicle. For example, a seat is held on the frame, on which a person, such as a male or female driver of the motor vehicle, can sit. In this case, the rear wheel is held rotatable at the rear wheel swing arm, in particular rotatable relative to the rear wheel swing arm about a rear wheel rotation axis. If the motor vehicle is driven along the ground while the motor vehicle is supported downwardly on the ground by ground contact elements in the vehicle height direction of the motor vehicle, the rear wheel rotates relative to the rear wheel swing arm and relative to the frame about the rear wheel rotation axis.

[0009] In order to achieve particularly favorable aerodynamics of the power locomotive here, in another design of the present invention, it is arranged that at least a part of the area of ​​the particle filter is arranged lower than at least a part of the area of ​​the rear wheel swing arm when viewed in the vehicle height direction. In other words, it is preferably arranged that the particle filter is at least partially, especially at least mainly and therefore at least more than half or completely arranged below the rear wheel swing arm in the vehicle height direction. This can avoid excessive air resistance of the power locomotive. In addition, a particularly favorable, especially neutral weight distribution of the power locomotive can be achieved, especially when viewed in the longitudinal direction of the vehicle. In addition, a particularly favorable weight distribution in the transverse direction of the vehicle of the power locomotive can be achieved, so that particularly favorable driving characteristics or particularly favorable driving performance of the power locomotive can be shown. The arrangement of the particle filter according to the present invention between the internal combustion engine and the rear wheel in the longitudinal direction of the vehicle can also achieve a favorable short response time of the particle filter, so that, for example, the particle filter can filter out particles that may be contained in the exhaust gas from the exhaust gas in a particularly short time after the start of the internal combustion engine, especially after a cold start. This can achieve particularly low-emission operation of the power locomotive.

[0010] In an advantageous embodiment of the invention, the locomotive has a transmission, by means of which the locomotive, in particular the rear wheel, can be driven by the internal combustion engine. For example, the transmission has a plurality of gears, in particular switchable gears, which in particular have transmission ratios that are different from one another, by means of which the locomotive, in particular the rear wheel, can be driven by the internal combustion engine. For example, the internal combustion engine has an output shaft, by means of which the internal combustion engine can provide a torque for driving the locomotive. In particular, when the internal combustion engine is designed as a reciprocating piston motor, the output shaft is designed as a crankshaft. The output shaft is, for example, connected or connectable to a transmission input shaft of the transmission in a torque-transmitting manner, in particular in a rotationally fixed manner, so that the corresponding torque provided or can be provided by the internal combustion engine via the output shaft can be transmitted from the output shaft to the transmission input shaft and can thus be introduced into the transmission. Via the transmission, the corresponding torque can, for example, be transmitted to the rear wheel, in order to thereby drive the rear wheel and thus the locomotive.

[0011] It has proven to be particularly advantageous if the particle filter is arranged at least partially between the transmission and the rear wheels, and thus between the internal combustion engine and the rear wheels, as viewed in the longitudinal direction of the vehicle, thereby enabling particularly advantageous aerodynamics and thus particularly efficient operation of the locomotive.

[0012] Another embodiment is characterized in that the particle filter is arranged at least partially, in particular at least predominantly and therefore at least more than half or completely, viewed in the longitudinal direction of the vehicle, between the transmission and the rear wheel so that the particle filter is at least partially, in particular at least predominantly and therefore at least more than half or completely, viewed in the longitudinal direction of the vehicle, between the transmission and the rear wheel so that the particle filter is at least partially, in particular at least predominantly and therefore at least more than half or completely, overlapped by the transmission in the longitudinal direction of the vehicle and at least partially, in particular at least predominantly and therefore at least more than half or completely, overlapped by the rear wheel in the longitudinal direction of the vehicle. This makes it possible, for example, to prevent the particle filter from being excessively flowed upon by the travel wind, for example when the motor vehicle is traveling forward, so that the air resistance of the motor vehicle can be kept particularly low.

[0013] In order to achieve a particularly quiet operation of the locomotive, in one embodiment of the invention, the muffler is arranged in the exhaust duct. In order to achieve a particularly short response time of the particle filter and particularly favorable aerodynamics of the locomotive, it can be provided that the particle filter is arranged in the muffler or upstream of the muffler. In particular, a particularly favorable position of the center of gravity of the particle filter can be achieved thereby. In other words, a favorable low position of the particle filter viewed in the vehicle height direction can be presented thereby, so that a particularly low position of the center of gravity of the locomotive can be achieved when viewed in the vehicle height direction.

[0014] Furthermore, it is conceivable that the particle filter can at least partially take over or support the acoustic function of a silencer, also referred to as an exhaust silencer, so that the weight of the locomotive can be kept particularly low. This ensures particularly efficient operation.

[0015] In order to be able to keep the weight, costs and installation space requirements of the exhaust duct particularly low and thus enable particularly efficient operation of the locomotive, in another embodiment of the invention it is provided that the particle filter has a catalytic coating. For example, the catalytic coating is configured as a three-way catalytic converter, i.e., it has a catalytic effect like a three-way catalytic converter, so that, for example, the catalytic coating is configured like a three-way catalytic converter to support or cause the carbon monoxide that may be contained in the exhaust gas to react chemically with oxygen to form carbon dioxide, the unburned hydrocarbons to react chemically with oxygen to form carbon dioxide and water, and the nitrogen monoxide to react chemically with carbon monoxide to form nitrogen and carbon dioxide. This makes it possible, for example, to omit a separate additional three-way catalytic converter in the exhaust duct, or the volume, weight and cost of such a three-way catalytic converter that is additionally provided if necessary can be advantageously kept low.

[0016] In another particularly advantageous embodiment of the invention, the exhaust duct has at least two exhaust flow channels (also referred to as flow channels for short), through which corresponding parts of the exhaust gas of the internal combustion engine can flow and which are separated from one another at least in corresponding subregions upstream of the particle filter. In this case, the particle filter is a common particle filter for the exhaust flow channels, through which parts of the exhaust gas that flow through the exhaust flow channels can flow. This makes it possible to avoid the use of a separate particle filter for each exhaust flow channel, so that the costs, weight and installation space requirements of the exhaust duct can be kept particularly low. As a result, particularly efficient operation of the locomotive can be achieved.

[0017] Finally, it has proven to be particularly advantageous if the particle filter has precisely one inlet or a plurality of inlets separated from one another, via which the exhaust gas can be introduced into the particle filter. In other words, the particle filter can be fed with an inflow of exhaust gas in a single-channel or multi-channel manner, for example via a manifold system, so that a particularly flow-favorable and thus low-loss supply of the particle filter with the exhaust gas can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Further details of the invention emerge from the following description of preferred embodiments and from the accompanying drawings.

[0019] in:

[0020] Figure 1 A schematic top view showing a first embodiment of a power locomotive; and

[0021] Figure 2A schematic top view of a second embodiment of a power locomotive is shown. DETAILED DESCRIPTION

[0022] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0023] Figure 1 A first embodiment of a motor vehicle 1 designed as a motorcycle is shown in a schematic top view, which in a first embodiment is designed as a single-track motor vehicle with exactly two wheels 2 and 3. Figure 1 It can be seen that the wheels 2 and 3 are arranged one behind the other in the longitudinal direction of the locomotive 1, also referred to as the vehicle, wherein Figure 1 The longitudinal direction of the vehicle is indicated by a double arrow 4. Wheel 2 is the front wheel, wherein wheel 3 is the rear wheel of the power locomotive 1. The power locomotive 1 has Figure 1 An unrecognizable frame in the example, for a male or female driver of the power locomotive 1 Figure 1 At least one seat which is also not identifiable remains at the frame. Figure 1 The front wheel fork, not shown in the figure, is pivotably held on the frame so that the front wheel fork can be pivoted relative to the frame about a steering axis. For example, the steering axis extends parallel to a plane spanned by the vehicle longitudinal direction and the vehicle height direction of the locomotive 1, wherein the vehicle height direction is indicated by a double arrow 5 and extends perpendicularly to the vehicle longitudinal direction. For example, the steering axis is inclined to or perpendicular to a second plane spanned by the vehicle longitudinal direction and the vehicle transverse direction of the locomotive 1, wherein Figure 1 The transverse direction of the vehicle in is indicated by a double arrow 6. The wheel 2 is held at the front wheel fork so as to be rotatable relative to the front wheel fork about a first wheel rotation axis 7 and can therefore be rotated relative to the front wheel fork and relative to the frame about the wheel rotation axis 7. Therefore, the wheel 2 and the wheel rotation axis 7 can be pivoted together with the front wheel fork about the steering axis relative to the frame and can therefore be steered together. If the front wheel fork and therefore the wheel 2 are pivoted relative to the frame about the steering axis, in particular during the driving of the locomotive 1 along the ground and in particular during the downward support of the locomotive 1 at the ground in the vehicle height direction via its wheels 2 and 3, which are also called ground contact elements or are configured as ground contact elements, this can cause the locomotive 1 to turn, change the driving direction and change lanes, so that the locomotive 1 is turned.

[0024] The power locomotive 1 also has Figure 1The rear wheel swing arm, which cannot be identified in the figure, is pivotally held on the frame, in particular so that the rear wheel swing arm can be pivoted relative to the frame around a pivot axis extending in the transverse direction of the vehicle. Here, the wheel 3 is rotatably held on the rear wheel swing arm around a second wheel rotation axis 8 relative to the rear wheel swing arm, so that the wheel rotation axis 8 and the wheel 3 can be pivoted together with the rear wheel swing arm around the pivot axis relative to the frame. During the driving of the above-mentioned locomotive 1 along the ground, the wheels 2 and 3 roll directly on the ground, and the wheel 2 rotates around the wheel rotation axis 7 relative to the frame, the rear wheel swing arm and the front wheel fork, and the wheel 3 rotates around the wheel rotation axis 8 relative to the rear wheel swing arm and relative to the frame and relative to the front wheel fork. For example, a steering handle, which is particularly configured as a steering gear, is arranged at the front wheel fork, and the male or female driver can grasp or grip the handle, so that the male or female driver can pivot the front wheel fork around the steering axis relative to the frame through the steering handle, and thus the locomotive 1 can be steered.

[0025] The locomotive 1 has an internal combustion engine 9, also referred to as a combustion engine or motor. The internal combustion engine 9 can be a component of a frame, so that, for example, the frame can include the internal combustion engine 9 as a first frame part. Furthermore, for example, the frame can include a second frame part that is constructed separately from the combustion engine and is connected to the internal combustion engine 9. With the help of the internal combustion engine 9, the wheels 3 (rear wheels) and thus the locomotive 1 as a whole can be driven. For this purpose, the internal combustion engine 9 has Figure 1 An output shaft which cannot be identified in the figure, through which the internal combustion engine 9 can provide a torque for driving the rear wheels. In particular, during the ignition operation of the internal combustion engine 9, the internal combustion engine 9 provides exhaust gas. In this case, the locomotive 1 has an exhaust duct 10 which is in particular constructed separately from the internal combustion engine 9 and through which the exhaust gas of the internal combustion engine 9 can flow. A particle filter 11 is arranged in the exhaust duct 10, with the help of which particles, in particular soot particles, can be filtered out of the exhaust gas. In a first embodiment, the internal combustion engine 9 is constructed as a gasoline engine, so that the particle filter 11 is constructed as a gasoline particle filter (OPF).

[0026] In order to achieve particularly favorable aerodynamics and thus particularly efficient operation of the locomotive 1, the particle filter 11 is arranged at least partially, in particular at least mainly and therefore at least more than half or completely, between the combustion engine 9 and the rear wheel (wheel 3) in the longitudinal direction of the vehicle (double arrow 4). In a first embodiment, the internal combustion engine 9 is configured as a reciprocating piston engine, for example. In this case, the internal combustion engine 9 has a motor body configured as a cylinder housing 12, which has or in particular directly delimits a plurality of cylinders and therefore at least or exactly two cylinders. The respective cylinder partially delimits the respective combustion chamber, in which the combustion process (exhaust gas generated by it) takes place during the ignition operation of the internal combustion engine 9. In this case, the particle filter 11 is arranged at least partially between the cylinder housing 12 and the rear wheel in the longitudinal direction of the vehicle, in particular so that the particle filter 11 is at least partially, in particular at least mainly and therefore at least more than half or completely overlapped by the cylinder housing 12 in the longitudinal direction of the vehicle, and at least partially overlapped by the rear wheel in the longitudinal direction of the vehicle. In order to be able to achieve a particularly advantageous position of the center of gravity of the locomotive 1, it is also preferably provided that the particulate filter 11 is arranged at least partially, in particular at least predominantly and therefore at least more than half or completely, lower than at least a portion of the rear wheel swing arm, in particular lower than the entire rear wheel swing arm, as viewed in the height direction of the vehicle.

[0027] For example, the power locomotive 1 has Figure 1 The transmission 13 shown schematically in particular in the figure, by means of which the rear wheels can be driven by the internal combustion engine 9, in particular by the output shaft. It is preferably provided that the particle filter 11 is arranged at least partially between the transmission 13 and the rear wheels as viewed in the longitudinal direction of the vehicle, in particular so that the particle filter 11 is at least partially overlapped by the transmission 13 in the longitudinal direction of the vehicle.

[0028] The exhaust passage 10 has at least or exactly two exhaust gas flow passages 14 and 15 through which corresponding parts of the exhaust gas can flow, which are at least partially separated from each other upstream of the particle filter 11 in the flow direction of the exhaust gas flowing through the exhaust passage 10. This can be understood, for example, that the exhaust gas from a first combustion chamber among the combustion chambers flows through the exhaust flow passage 14, while the exhaust gas from a second combustion chamber among the combustion chambers flows through the exhaust flow passage 15, while at the same time, for example, the exhaust gas from the second combustion chamber does not flow through the exhaust flow passage 14, while the exhaust gas from the first combustion chamber does not flow through the exhaust flow passage 15. Therefore, the exhaust gas flowing from the first combustion chamber through the exhaust flow passage 14 is the first part of the mentioned parts of the exhaust gas, and the exhaust gas flowing from the second combustion chamber through the exhaust flow passage 15 is the second part of the parts of the exhaust gas. For example, from Figure 1 It can be seen that the particle filter 11 is a common particle filter for the exhaust gas ducts 14 and 15 , through which the exhaust gas flowing through the exhaust gas duct 14 as well as the exhaust gas flowing through the exhaust gas duct 15 can flow.

[0029] A first catalytic converter 16 is arranged in the exhaust gas flow channel 14 and thus upstream of the particle filter 11, while a second catalytic converter 17 is arranged in the exhaust gas flow channel 15 and thus upstream of the particle filter 11, wherein the catalytic converters 16 and 17 are separate, separate components arranged outside of each other. In particular, the respective catalytic converters 16, 17 are designed as three-way catalytic converters. Preferably, the particle filter 11 has a catalytic coating, which is preferably designed as a three-way catalytic converter and thus has a catalytic effect like a three-way catalytic converter. The end pipe of the exhaust gas channel 10 is located at Figure 1 In the figure, the exhaust tract 10 is designated by 18, wherein the exhaust tract 10 opens into the surroundings 19 of the locomotive 1 via an end pipe 18. It is conceivable that the end pipe 18 is arranged downstream of the particle filter 11.

[0030] Furthermore, the silencer 20 is arranged in the exhaust duct 10. In order to achieve a particularly small installation space requirement for the exhaust duct 10 and thus achieve particularly favorable aerodynamics for the locomotive 1, in a first embodiment, it is provided that the particle filter 11 is arranged in the silencer 20, in particular in its housing. Furthermore, a particularly favorable position of the center of gravity of the locomotive 1 can be achieved thereby.

[0031] Figure 2 A second embodiment of the locomotive 1 is shown in a schematic top view. The second embodiment differs from the first embodiment in particular in that the particle filter 11 is arranged outside the muffler 20 in the second embodiment and is arranged upstream of the muffler 20. Also in the second embodiment, the particle filter 11 is a common particle filter for the exhaust gas flow channels 14 and 15.
