Description

Technical Field

[0001] This utility model relates to the field of vehicle axle technology, and in particular to a rigid torsion damping vehicle axle that is easy to install. Background Technology

[0002] The axle is a key component of the vehicle chassis. Essentially, it is a "bridge" that "connects the wheels and transmits force and motion." It connects the left and right wheels on one side and is connected to the frame / body through the suspension on the other side. It is the basic carrier for realizing vehicle driving, load-bearing, steering and braking.

[0003] For example, Chinese patent CN221090377U discloses an axle with shock absorption function, including an axle body and two mounting seats. A connecting block is provided between the mounting seats and the axle body. The bottom surface of the connecting block is fixedly connected to the upper end of the axle body. A storage groove is provided on the front of the connecting block. A slide plate that can move up and down is provided in the storage groove. A connecting post is provided in the middle of the upper end surface of the slide plate. The upper end of the connecting post slides through the connecting block and connects to the bottom surface of the mounting seat. Damping shock absorbers are symmetrically provided at the bottom of the slide plate. A shock-absorbing spring is provided on the outer sleeve of the damping shock absorber. Support plates are provided at both the upper and lower ends of the damping shock absorber. The bottom surface of the slide plate and the inner bottom of the storage groove are provided with embedded grooves corresponding to the support plates. The support plates slide in the embedded grooves.

[0004] In the aforementioned patent, although the problem of difficulty in maintaining the shock absorption mechanism is solved by using pull rings and cover plates, the support plate and the embedded groove are in sliding fit. Although a first rubber pad is provided for buffering, the rubber parts will gradually age and wear due to long-term high-frequency vibration and compression, which will increase the gap between the support plate and the embedded groove and cause abnormal noise. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the support plate and the embedded groove are in a sliding fit. Although a first rubber pad is provided for buffering, the rubber parts will gradually age and wear due to long-term high-frequency vibration and compression, which will increase the gap between the support plate and the embedded groove and cause abnormal noise. Therefore, this invention proposes a rigid torsion damping axle that is easy to install.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rigid torsion damping axle that is easy to install, comprising an axle body, a buffer mechanism provided on one side of the axle body, the buffer mechanism comprising an auxiliary box, a mounting component and a guide plate, a damping rod hinged to the inner wall of the auxiliary box, one end of the damping rod being hinged to the guide plate, guide wheels being rotatably connected to both sides of the guide plate, an inner rod being fixedly connected to one side of the guide plate, a buffer pad being fixedly connected to the outer ring surface of the inner rod, a sleeve rod being slidably connected to one end of the inner rod, and one end of the sleeve rod being fixedly connected to the inner wall of the auxiliary box.

[0007] Preferably, the sleeve rod and the inner rod are externally fitted with springs, and the two ends of the springs are respectively connected to the guide plate and the auxiliary box.

[0008] Preferably, a second connector is fixedly connected to one side of the auxiliary box, and an arc-shaped component is inserted into one side of the second connector. The inner wall of the arc-shaped component is fixedly connected to the axle body.

[0009] Preferably, one end of the arc-shaped component is fixedly connected to a connector, one side of the connector is inserted into the auxiliary box, and a bolt is installed between the auxiliary box and the connector.

[0010] Preferably, a first mounting block is fixedly connected to one side of the guide plate, and a second mounting block overlaps one side of the first mounting block. The second mounting block and the first mounting block are connected by a limit bolt through a threaded connection.

[0011] Preferably, a reinforcing plate is fixedly connected to one side of the second mounting block, and a buffer spring is fixedly connected to one side of the reinforcing plate. The buffer spring is arc-shaped.

[0012] Preferably, a mounting component is fixedly connected to one side of the buffer spring, and a mounting hole is provided on one side of the mounting component.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the two ends of the damping rod are hinged to the auxiliary box and the guide plate respectively, and the inner rod and the sleeve rod are slidably connected. After the guide plate is subjected to force, it moves along the inner wall of the auxiliary box. The inner rod moves with the guide plate, and the sleeve rod is compressed. The damping rod and the sleeve rod buffer one side of the guide plate. The rolling of the guide wheel can reduce the friction on the inner wall of the auxiliary box, reduce the wear and aging of the buffer pad, and thus reduce the probability of abnormal noise inside the buffer mechanism.

[0015] 2. In this utility model, the arc-shaped part is inserted into the connector two, and the mounting block one and the mounting block two are connected by a limiting bolt. The connector two is inserted into the arc-shaped part, and the connector one is inserted into the auxiliary box, which facilitates the installation and removal of the auxiliary box on the axle body. The mounting block one and the mounting block two are connected by the limiting bolt, which facilitates the installation of the reinforcing plate on one side of the guide plate. The mounting parts facilitate the installation of the entire axle. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Refer to Figures 1-5 As shown: A rigid torsion damping axle that is easy to install includes an axle body 1. A buffer mechanism is provided on one side of the axle body 1. The buffer mechanism includes an auxiliary box 2, a mounting component 3, and a guide plate 14. A damping rod 12 is hinged to the inner wall of the auxiliary box 2. One end of the damping rod 12 is hinged to the guide plate 14. Guide wheels 13 are rotatably connected to both sides of the guide plate 14. An inner rod 16 is fixedly connected to one side of the guide plate 14. A buffer pad 17 is fixedly connected to the outer ring surface of the inner rod 16. A sleeve rod 15 is slidably connected to one end of the inner rod 16. One end of the sleeve rod 15 is fixedly connected to the inner wall of the auxiliary box 2. A spring 18 is sleeved on the outside of the sleeve rod 15 and the inner rod 16. The two ends of the spring 18 are respectively connected to the guide plate 14 and the auxiliary box 2.

[0025] When the guide wheel 13 moves with the guide plate 14, it rolls along the inner wall of the auxiliary box 2, reducing the friction between the guide plate 14 and the inner wall of the auxiliary box 2. At the same time, the inner rod 16 slides in the sleeve rod 15 to guide the guide plate 14, which can prevent the guide plate 14 from deviating and ensure the stability of the buffer movement direction. The spring 18 is compressed and absorbs most of the vibration energy through elastic potential energy conversion. The damping rod 12 suppresses the reciprocating vibration of the spring 18 through "damping force", further optimizing the shock absorption effect. Finally, a balance between rigid torque transmission and flexible vibration absorption is achieved. The shock absorption effect of the axle can be improved through the buffer pad 17, spring 18 and damping rod 12.

[0026] Example 2: Figures 1-3 As shown, a second connector 10 is fixedly connected to one side of the auxiliary box 2, and an arc-shaped component 11 is inserted into one side of the second connector 10. The inner wall of the arc-shaped component 11 is fixedly connected to the axle body 1. A first connector 5 is fixedly connected to one end of the arc-shaped component 11. One side of the first connector 5 is inserted into the auxiliary box 2, and a bolt is installed between the auxiliary box 2 and the first connector 5. An installation block 7 is fixedly connected to one side of the guide plate 14. An second installation block 9 overlaps one side of the first installation block 7. A limit bolt 8 is threadedly connected between the second installation block 9 and the first installation block 7. A reinforcing plate 6 is fixedly connected to one side of the second installation block 9. A buffer spring 4 is fixedly connected to one side of the reinforcing plate 6. The buffer spring 4 is arc-shaped. An installation component 3 is fixedly connected to one side of the buffer spring 4. An installation hole is opened on one side of the installation component 3.

[0027] The arc-shaped component 11 increases the contact area with the axle body 1 through a "fitting design". Combined with the "double plug-in positioning" of the first plug-in component 5 and the second plug-in component 10, plus the "rigid locking" of the bolt, it ensures that the auxiliary box 2 and the axle body 1 form a stable overall support structure, which facilitates the quick installation of the auxiliary box 2 on the axle body 1. When the vehicle generates torque or vibration during driving, the vibration of the frame is first transmitted to the mounting component 3. The arc-shaped buffer spring 4 uses its own elastic deformation to initially absorb low-frequency vibration. The reinforcing plate 6 plays a "force dispersion" role, avoiding stress concentration of the buffer spring 4. The mounting hole design of the mounting component 3 facilitates quick docking with the frame. The first mounting block 7 and the second mounting block 9 are detachably connected by the limit bolt 8, which facilitates the disassembly and replacement of the mounting component 3.

[0028] The usage method and working principle of this device are as follows: First, overlap one side of mounting block 2 9 with mounting block 1 7. Insert a limiting bolt 8 inside mounting block 1 7 and mounting block 2 9. Then, install a nut at the end of the limiting bolt 8 for fixation, thus connecting the guide plate 14 and the mounting part 3. Attach the auxiliary box 2 to one side of the axle body 1, and attach the arc-shaped part 11 to the other side of the axle body 1. Insert the arc-shaped part 11 into the connector 2 10, and the connector 1 5 into the auxiliary box 2. Then, attach the connector 11 into the auxiliary box 2. The auxiliary box 2 is fixed at the connection point by bolts, which can realize the installation of the auxiliary box 2 on the axle body 1. When the mounting part 3 is subjected to external force, the buffer spring 4 provides initial buffering, the reinforcing plate 6 applies force to the guide plate 14, the guide wheel 13 travels along the inner wall of the auxiliary box 2 and applies force to the damping rod 12, the spring 18 is compressed, and the inner rod 16 slides inside the sleeve rod 15 until the buffer pad 17 of hydrogenated nitrile rubber overlaps with the sleeve rod 15, thereby achieving buffering and shock absorption on one side of the guide plate 14.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
