Description

Technical Field

[0001] The utility model relates to the technical field of reverse tricycles, in particular to a reverse tricycle rear power suspension device. Background Art

[0002] A reverse tricycle is a type of tricycle, generally with two wheels in the front and one wheel in the rear. When viewed from the front, it resembles the front of a sedan, having two wheels, while the rear has only one wide and thick wheel. This vehicle is divided into two types: automatic transmission and manual transmission. It is convenient to operate during use and not easy to fall.

[0003] Existing reverse tricycles usually have the power in the front. When encountering poor ground conditions, the vibration amplitude of the vehicle is relatively large, affecting the driving and riding comfort of the people inside the vehicle.

[0004] Therefore, the present application provides a reverse tricycle rear power suspension device to overcome the defects of the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that when the existing front-powered reverse tricycle encounters poor ground conditions, the vibration amplitude of the vehicle is relatively large, affecting the driving and riding comfort of the people inside the vehicle.

[0006] The technical solution of the utility model provides a reverse tricycle rear power suspension device, including a motor. One side of the motor is fixedly connected with a gearbox. The output shaft of the motor is in transmission connection with the gear in the gearbox. One side of the gearbox is fixedly connected with a hollow single cantilever. The end of the single cantilever far from the gearbox is rotatably connected with a wheel. The transmission shaft in the gearbox penetrates through the single cantilever and is in transmission connection with the wheel. A connecting beam is fixed on the left side of the single cantilever. A first support arm is hinged on the top wall of the connecting beam. A composite shock-absorbing spring is sleeved on the first support arm. One end of the connecting beam is fixedly connected with the first support arm, and the other end is fixedly connected with a support arm mechanism. The support arm mechanism can be regarded as a connecting arm. A balance beam is fixed on the left side of the support arm mechanism. The balance beam and the connecting beam are arranged on both sides of the wheel. A second support arm is hinged on the balance beam. A balance shock-absorbing spring is sleeved on the second support arm. The tops of the first support arm and the second support arm are connected to the vehicle frame.

[0007] As a preferred technical solution, a brake disc is installed on the wheel, and a buffer rubber sleeve is installed on the side of the support arm mechanism far from the connecting beam.

[0008] The beneficial effects of the reverse tricycle rear power suspension device provided by the utility model are as follows:

[0009] The utility model is driven by a rear power. The wheels are only connected to the connecting beam through a single cantilever at the front side, and are not connected to the balance beam at the rear side. Instead, they are connected to the balance beam through a support arm mechanism. When encountering poor ground conditions, the vehicle is first shock-absorbed by a composite shock-absorbing spring and then by a balance shock-absorbing spring, which can reduce the vibration amplitude of the vehicle, reduce the impact of poor ground conditions on the passengers in the vehicle, and improve the driving and riding comfort.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the technical means, technical features, utility model purpose and technical effects achieved by the utility model easy to understand, the following further elaborates the utility model in conjunction with specific drawings; obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0016] Embodiment

[0017] As Figures 1 to 4As shown: An inverted three-wheeled rear-mounted power suspension device includes a motor 1. One side of the motor 1 is fixedly connected to a gearbox 2. The output shaft of the motor 1 is in gear transmission connection with the gears in the gearbox 2. One side of the gearbox 2 is fixedly connected to a hollow single cantilever 3. The end of the single cantilever 3 far from the gearbox 2 is rotatably connected to a wheel 4. The transmission shaft in the gearbox 2 passes through the single cantilever 3 and is in transmission connection with the wheel 4. A connecting beam 5 is fixed on the left side of the single cantilever 3. A first support arm 6 is hinged on the top wall of the connecting beam 5. A composite shock-absorbing spring 7 is sleeved on the first support arm 6. One end of the connecting beam 5 is fixedly connected to the first support arm 6, and the other end is fixedly connected to a support arm mechanism 8. The support arm mechanism 8 can be regarded as a connecting arm. A balance beam 9 is fixed on the left side of the support arm mechanism 8. The balance beam 9 and the connecting beam 5 are arranged on both sides of the wheel 4. A second support arm 10 is hinged on the balance beam 9. A balance shock-absorbing spring 11 is sleeved on the second support arm 10. The tops of the first support arm 6 and the second support arm 10 are connected to the vehicle frame.

[0018] A brake disc 12 is installed on the wheel 4. A buffer rubber sleeve 13 is installed on the side of the support arm mechanism 8 far from the connecting beam 5.

[0019] Working mode: The output shaft of the motor transmits power to the gears in the gearbox. The gears in the gearbox transmit power to the transmission shaft. The transmission shaft drives the wheel to rotate, thereby driving the vehicle to move. During driving, when the wheel encounters stones or the ground is uneven, the wheel feeds back the ground conditions to the composite shock-absorbing spring on the first support arm through the single cantilever and the connecting beam to shock-absorb the vehicle. Then, through the support arm mechanism and the balance beam, the ground conditions are fed back to the balance shock-absorbing spring on the second support arm to shock-absorb the vehicle. This mechanism can reduce the vibration amplitude of the vehicle, reduce the impact of poor ground conditions on the passengers in the vehicle, and improve the driving and riding comfort.

[0020] In summary, the above is only a preferred embodiment of the present invention and is not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the scope of the patent application of the present invention shall fall within the technical scope of the present invention.
