Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of automobiles, in particular to a double-motor driving mechanism suitable for manual transmission vehicle. BACKGROUND
[0002] Manual transmission vehicles are more complex to operate than automatic transmission vehicles, especially for drivers who are not familiar with the technology. In an emergency, they often cannot control the clutch pedal, brake pedal and accelerator pedal in time and accurately, resulting in delayed braking or engine stall. For example, if the clutch is not fully depressed, the connection between the engine and the transmission may be unstable, which can easily cause the engine to stall when braking. Or if the brake is directly pressed to the bottom without simultaneously pressing the clutch, the engine load will suddenly increase, causing the engine to stall. Or when the gear is too high and the vehicle speed is too slow, the brake will cause the engine speed to drop rapidly, and if the gear is not reduced or the clutch is not pressed in time, it will also cause the engine to stall. Especially for students learning to drive manual vehicles, they often cannot master the essentials when they first operate, and the clutch control is unstable, which frequently causes the engine to stall. Sudden engine stall or delayed braking while driving is very dangerous, and traffic accidents are likely to occur in such situations. In addition, frequent engine stall of manual transmission vehicles also affects the service life of the vehicle.

[0019] The present application provides a dual-motor driving mechanism suitable for a manual transmission vehicle, as shown in the accompanying drawings, comprising: Figure 1
[0020] a transmission mechanism 100, comprising a clutch transmission rod 110 and a brake transmission rod 120, one end of the clutch transmission rod 110 being connected with a clutch pedal, and one end of the brake transmission rod 120 being connected with a brake pedal;
[0021] a dual-motor driving mechanism 200, comprising a clutch driving motor 210 connected with a crankshaft of the clutch transmission rod 100 and a brake driving motor 220 connected with a crankshaft of the brake transmission rod 120;
[0022] a linkage mechanism 300 for connecting the transmission mechanism 100 and the dual-motor driving mechanism 200, comprising a clutch linkage mechanism 310 connecting the clutch transmission rod 110 and the clutch driving motor 210 and a brake linkage mechanism 320 connecting the brake transmission rod 120 and the brake driving motor 220;
[0023] The dual-motor driving mechanism 200 and the linkage mechanism 300 are located in the co-driver cabin, and the two motors are arranged in close proximity, so that the structure layout is more compact, the limited space in the driver cabin cannot accommodate the motors is avoided, and the running state of the two motors can be conveniently checked and viewed at the same time. The dual-motor driving mechanism 200 is connected with a vehicle control system, and the transmission mechanism 100 is driven to step on the clutch pedal and the brake pedal by the dual-motor driving mechanism 200, so as to realize automatic braking.
[0024] The application can realize automatic brake function by pressing clutch pedal and brake pedal at the same time when some limiting conditions such as obstacle or high speed are detected by automobile radar, so as to avoid emergency brake delay, prevent driver from forgetting to press clutch pedal and causing automobile engine to stop, improve driving safety factor of manual transmission vehicle and reduce wear and tear of manual transmission vehicle.
[0025] For example, in the double-motor driving mechanism suitable for manual transmission vehicle provided in an embodiment, as shown in Figure 1 The clutch transmission rod 110 and the brake transmission rod 120 each include a straight rod 111 and a bent rod 112 connected perpendicularly to one end of the straight rod 111, one end of the straight rod 111 away from the bent rod 112 is fixedly arranged in the co-pilot cabin, the bent rod 112 is located in the driver cabin, the bent rod 112 of the clutch transmission rod 110 is connected with the clutch pedal, and the bent rod 112 of the brake transmission rod 120 is connected with the brake pedal.
[0026] For example, in the double-motor driving mechanism suitable for manual transmission vehicle provided in an embodiment, as shown in Figure 1 The clutch linkage mechanism 310 and the brake linkage mechanism 320 each include a pull rod 311, a swing arm 312 and a guide rod 313, one end of the pull rod 311 of the clutch linkage mechanism 310 is connected with the output end of the clutch driving motor 210, one end of the pull rod 311 of the brake linkage mechanism 320 is connected with the output end of the brake driving motor 220; one end of the swing arm 312 of the clutch linkage mechanism 310 is fixedly connected with the straight rod 111 of the clutch transmission rod 110, one end of the swing arm 312 of the brake linkage mechanism 320 is fixedly connected with the straight rod 111 of the brake transmission rod 120; one end of the guide rod 313 of the clutch linkage mechanism 310 is sleeved on the pull rod 311, and the other end is movably connected with the free end of the swing arm 312 through a pin shaft 314; one end of the guide rod 313 of the brake linkage mechanism 320 is sleeved on the pull rod 311, and the other end is movably connected with the free end of the swing arm 312 through a pin shaft 314.
[0027] The clutch driving motor 210 and the brake driving motor 220 pull the pull rod 311 and drive the swing arm 312 to swing, and then drive the bent rod 112 to pull the clutch pedal / brake pedal, so as to realize double-motor joint driving, press the clutch pedal and the brake pedal at the same time, and realize automatic brake.
[0028] For example, in the double-motor driving mechanism suitable for manual transmission vehicle provided in an embodiment, as shown in Figure 1As shown in the drawings, the end of the swing arm 312 away from the clutch transmission rod 110 / brake transmission rod 120 is provided with a plurality of axially arranged pin holes 3121, and the guide rod 313 is provided with a guide groove 3131 through which the pin shaft 314 passes.
[0029] According to the above embodiment, by providing a plurality of pin holes 3121 on the swing arm 312 and a guide groove 3131 on the guide rod 313, the distance and connection angle between the swing arm 312 and the guide rod 313 can be adjusted to adapt to the installation requirements of different vehicle models.
[0030] Since the clutch pedal in a manual transmission vehicle is located on the left side of the vehicle body compared to the brake pedal, the displacement of the clutch pedal is longer, and when the driver independently steps on the clutch pedal in the non-starting state of the dual-motor driving mechanism 200, in order to ensure that the clutch transmission rod 110 rotates synchronously with the fluctuation of the clutch pedal, for example, in an embodiment of the dual-motor driving mechanism suitable for manual transmission vehicles, as shown in Figure 1 , the clutch linkage mechanism 310 further includes a reset mechanism, and the reset mechanism includes a reset spring 315, one end of the reset spring 315 is fixedly connected with the pull rod 311, and the other end is fixedly connected with the swing arm 312.
[0031] According to the above embodiment, by connecting a reset spring 315 between the pull rod 311 and the swing arm 312 of the clutch linkage mechanism 310, when the driver independently steps on the clutch pedal, the clutch transmission rod 110 rotates synchronously with the fluctuation of the clutch pedal, and at the same time the reset spring 315 is stretched, and when the driver releases the clutch pedal, the clutch transmission rod 110 is reset under the restoring force of the reset spring 315, thereby ensuring that the clutch transmission rod 110 moves synchronously with the clutch pedal, and avoiding the situation that the clutch pedal cannot be stepped on or cannot be reset due to excessive travel and movement resistance of the clutch transmission rod 110.
[0032] For example, in an embodiment of the dual-motor driving mechanism suitable for manual transmission vehicles, as shown in Figure 1 , the reset mechanism further includes a fixed block 316 sleeved on the pull rod 311, a first bolt 317 is arranged on the fixed block 316, one end of the reset spring 315 is sleeved on the first bolt 317, a second bolt 318 is inserted in the pin hole 3121 of the swing arm 312, the other end of the reset spring 315 is sleeved on the second bolt 318, and the maximum stretching length of the reset spring 315 is less than or equal to the maximum swing distance of the swing arm 312, thereby ensuring that the reset spring 315 generates sufficient restoring force to reset the clutch transmission rod 110 after stretching.
[0033] For example, in an embodiment of the dual-motor driving mechanism suitable for manual transmission vehicles, as shown inFigure 1 As shown in the figure, an adapter shaft 113 is provided at the end of the bent rod 112 away from the straight rod 111, and a clamping plate 114 is provided on the adapter shaft 113 for connecting with the clutch pedal / brake pedal.
[0034] The same design purpose as the reset spring 315 is to ensure that the clutch transmission rod 110 rotates synchronously with the clutch pedal when the driver steps on the clutch pedal, for example, in an embodiment of the double-motor drive mechanism suitable for manual transmission vehicles, as shown in the figure, Figure 1 As shown in the figure, a limiting frame 115 is provided on the adapter shaft 113, the two ends of the limiting frame 115 are connected with the two ends of the adapter shaft 113 and form a limiting space, the bent rod 112 is provided in the limiting space, and when the driver steps on the clutch pedal, the limiting frame 115 can suppress the synchronous rotation of the clutch transmission rod 110, avoiding the situation that the clutch transmission rod 110 cannot rotate synchronously with the clutch pedal due to excessive stroke and movement friction.
[0035] For example, in an embodiment of the double-motor drive mechanism suitable for manual transmission vehicles, as shown in the figure, Figure 1 As shown in the figure, a transmission mechanism mounting seat 130 is provided in the passenger compartment, and the straight rod 111 of the clutch transmission rod 110 and the brake transmission rod 120 away from the bent rod 112 is fixedly connected with the transmission mechanism mounting seat 130 through a bearing 116.
[0036] For example, in an embodiment of the double-motor drive mechanism suitable for manual transmission vehicles, as shown in the figure, Figure 1 As shown in the figure, a clamp 117 is provided on both sides of the bearing 116 on the straight rod 111 to limit the axial offset of the straight rod 111.
[0037] According to the above embodiment, by providing a clamp 117 on the fixed end of the straight rod 111, the clutch transmission rod 110 and the brake transmission rod 120 can be prevented from being laterally offset along the axial direction of the straight rod under the action of lateral force during long-term use, ensuring that the straight rod 111 is axially fixed.
[0038] Although the embodiments of the present application have been disclosed as above, they are not limited to the application and implementation listed in the specification and embodiments, and can be fully applied to various fields suitable for the present application, and additional modifications can be easily realized by those skilled in the art, therefore the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and equivalent scope.
