Description

Technical Field

[0001] This utility model belongs to the field of tricycle suspension technology, and in particular relates to an independent suspension system for tricycles. Background Technology

[0002] Three-wheeled electric vehicles are three-wheeled transportation tools powered by batteries and driven by motors. They are mainly used for carrying goods or people and are classified into household, freight, and factory types according to their uses. They are equipped with large-capacity batteries and traction motors, and their structure is adapted to narrow roads and has a reversing function. They are suitable for short-distance family transportation, urban and rural freight transportation, and sanitation in factories and mines.

[0003] However, in actual use, the rear wheel suspension of existing electric tricycles is a solid axle type, which keeps the drive wheels on both sides of the axis fixed. This causes the tricycle to tilt and bounce more when it moves on bumpy roads or when one side of the wheel is undulating, thus affecting the stability of the tricycle. Utility Model Content

[0004] The purpose of this utility model is to propose an independent suspension system for tricycles in order to solve the problem of poor anti-bumping effect of traditional solid axle suspensions for tricycles.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tricycle independent suspension system, comprising two mounting brackets, a second universal joint transmission mechanism mounted on one side of each mounting bracket, and a mounting plate head connected to the output end of the second universal joint transmission mechanism, and further comprising:

[0006] The gearbox has a first universal joint transmission mechanism connected to both output ends on both sides, and a drive motor is fixedly installed on one side of the gearbox, with the output shaft of the drive motor connected to one side of the transmission gear inside the gearbox.

[0007] A transmission rod, one end of which is connected to the input end of the second universal joint transmission mechanism, and the other end of which is connected to the output end of the first universal joint transmission mechanism.

[0008] As a further description of the above technical solution:

[0009] The mounting bracket is connected to a base frame at the top, and a hinge rod is hinged inside the base frame.

[0010] As a further description of the above technical solution:

[0011] The top of the hinge rod is connected to a shock absorber, and the outer wall of the shock absorber is fitted with a damping spring.

[0012] As a further description of the above technical solution:

[0013] The top of the shock absorber is connected to a mounting sleeve, and the mounting sleeve is a rubber sleeve.

[0014] As a further description of the above technical solution:

[0015] The mounting bracket has two mounting seats connected to its bottom, and the two mounting seats on the same side are arranged opposite each other.

[0016] As a further description of the above technical solution:

[0017] Furthermore, a stabilizing bar is installed between the mounting bases at the bottom of the two mounting brackets, and the stabilizing bar is centered.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting two mounting brackets and installing them on the tricycle frame respectively, the two rear drive wheels are directly disconnected from the axle connection. As a result, when one drive wheel of the tricycle encounters a bump, the movement of the drive wheel on that side will not be directly transmitted to the drive wheel on the other side, thereby greatly reducing vehicle vibration and impact and improving ride comfort.

[0020] 2. In this utility model, by setting a stabilizer bar and connecting the mounting brackets on both sides through the stabilizer bar, the stabilizer bar can improve the handling stability of the tricycle, precisely control the drive wheel positioning parameters, and reduce axle roll, thereby making the vehicle more stable and responsive when turning and changing lanes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a technical solution: an independent suspension system for a tricycle, including two mounting brackets 1. A second universal joint transmission mechanism 10 is mounted on one side of the mounting bracket 1, and the output end of the second universal joint transmission mechanism 10 is connected to a mounting disc head 11. It also includes a reduction gearbox 4 and a transmission rod 9. The output ends of both sides of the reduction gearbox 4 are connected to a first universal joint transmission mechanism 8, and a drive motor 5 is fixedly mounted on one side of the reduction gearbox 4. The output shaft of the drive motor 5 is connected to one side of the transmission gear inside the reduction gearbox 4. One end of the transmission rod 9 is connected to the input end of the second universal joint transmission mechanism 10, and the other end of the transmission rod 9 is connected to the output end of the first universal joint transmission mechanism 8. A base frame 13 is connected to the top of the mounting bracket 1, and a hinge rod 14 is hinged inside the base frame 13. A shock absorber 2 is connected to the top of the hinge rod 14, and a damping spring 3 is sleeved on the outer wall of the shock absorber 2. A mounting rubber sleeve 12 is connected to the top of the shock absorber 2, and the mounting rubber sleeve 12 is a rubber sleeve.

[0027] In a specific implementation, by setting two mounting brackets 1, which are respectively installed on the bottom of the tricycle frame, the two rear drive wheels have better tire contact with the ground. When on uneven roads or when turning, each wheel can adapt to the undulations of the road surface more independently, maintain the contact area between the tire and the ground, and improve grip, traction and braking performance. The independent suspension does not have a rigid axle running through the left and right sides, which provides more space for the arrangement of drive unit, battery, drive shaft, fuel tank, etc. The shock absorber 2 suppresses the reciprocating oscillation of the damping spring 3 and quickly attenuates the vibration of the vehicle body.

[0028] The bottom of the mounting bracket 1 is connected to two mounting seats 7, and the two mounting seats 7 on the same side are arranged opposite each other. A stabilizing rod 6 is installed between the mounting seats 7 at the bottom of the two mounting brackets 1, and the stabilizing rod 6 is arranged in the center.

[0029] In a specific implementation, by setting a stabilizer bar 6, the tricycle generates centrifugal force when turning, causing the vehicle body to tilt, the outer suspension to be compressed, the inner suspension to be stretched, and the stabilizer bar 6 to twist. Its stiffness is used to resist the tilt of the vehicle body, so that the two suspensions are linked to each other, improving the cornering stability. Furthermore, the reduction gearbox 4 and the drive motor 5 are both installed through hanging points. This technology is existing technology and does not need to be described in detail.

[0030] Working principle: When in use, the mounting brackets 1 on both sides are installed on the bottom sides of the tricycle frame, so that the drive wheels on both sides are separated. This avoids the two drive wheels being rigidly connected by a single axle, which makes the traditional suspension structure have poor handling. When one drive wheel bounces, it will force the other drive wheel to move in tandem, resulting in large body sway and affecting tire contact with the ground.

[0031] In this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
