Description

Technical Field

[0001] This utility model relates to the field of rear axle stabilizer bar technology, and in particular to the left and right suspension tube assembly of the rear axle stabilizer bar. Background Technology

[0002] The rear stabilizer bar, also known as an anti-roll bar or balance bar, is an important component of a car's suspension system, primarily mounted on the rear axle. Its working principle is based on leverage. When a vehicle performs maneuvers such as cornering, the body rolls. At this time, the rear stabilizer bar comes into play. Due to the body roll causing different travel on the left and right suspension sides, one end of the stabilizer bar twists relative to the other. This torsional force creates a balancing force between the left and right suspensions, limiting excessive compression on one side and preventing excessive extension on the other, thus effectively reducing the degree of body roll. A search revealed Chinese Patent Publication No. CN200988409Y, which discloses a rear axle stabilizer bar assembly for automobiles. The assembly includes a stabilizer bar link, stabilizer bar connecting sleeves fixedly connected to both ends of the stabilizer bar link, and a stabilizer bar mounting sleeve perpendicularly fixed to the stabilizer bar connecting sleeve. The main advantages of this rear axle stabilizer bar assembly are that it is manufactured using machining and separate welding, simplifying the production process, increasing production efficiency, and minimizing changes in material properties. The welded stabilizer bar mounting sleeve and stabilizer bar connecting sleeve employ a semi-circular arc contact welding shape to ensure connection strength and improve structural force distribution. However, the locking structure of this device is not flexible enough, resulting in insufficient stability under complex road conditions. Furthermore, disassembly is inconvenient during inspection and maintenance, affecting maintenance efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a rear axle stabilizer bar left and right hanger assembly, which solves the problems of insufficient flexibility and inconvenient disassembly of the locking mechanism of ordinary rear axle stabilizer bars in the prior art.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-4 The present invention relates to a rear axle stabilizer bar left and right suspension tube assembly, which includes: a stabilizer bar 1, with multi-stage bushings 2 fixedly connected to the lower left and right ends of the stabilizer bar 1. The multi-stage bushings 2 can provide multi-layered buffering for the connecting tube 102, effectively dispersing impact force and extending service life; a connecting tube 102 is fixedly connected to the lower bottom of the multi-stage bushings 2, and a locking mechanism 3 is fixedly connected to the other end of the connecting tube 102. The locking mechanism 3 helps to make the connection between the suspension tube 4 and the connecting tube 102 more secure and reliable, ensuring that the suspension tube 4 is not easy to loosen during aggressive driving; and fixed side plates 301 are fixedly connected to the left and right ends of the locking mechanism 3. A fixed shaft 302 is fixedly connected to the inner center of the fixed side plate 301. A first ratchet 303 is fixedly connected to the other end of the fixed shaft 302. A hole is opened in the center of the other end of the fixed side plate 301, and a rotating handle 304 is provided in the hole. A pressing block is provided at the end of the rotating handle 304 facing the inner side of the fixed side plate 301. The locking mechanism 3 also includes an elastic pressing block 305 and a second ratchet 306. The elastic pressing block 305 is disposed between the pressing block and the second ratchet 306, and the second ratchet 306 is disposed opposite to the first ratchet 303. When the operator rotates the rotating handle 304, the pressing block on the rotating handle 304 rotates and acts on the elastic pressing block 305. The elastic compression block 305 deforms under the action of the compression block (its internal spring post 305a is compressed), driving the second ratchet 306 to move towards the first ratchet 303, so that the first ratchet 303 and the second ratchet 306 are interlocked to form a tight engagement, ensuring that the locking mechanism 3 is stable and reliable. When the handle 304 is loosened or rotated in the opposite direction, the spring post inside the elastic compression block 305 releases its elastic force, pushing the elastic compression block 305 to reset, thereby driving the second ratchet 306 to separate from the first ratchet 303, achieving quick unlocking; reliable, the elastic compression block 305 is equipped with a spring inside to assist its rebound reset, enhance the locking force, and improve the stability and safety of the overall structure; The multi-stage bushing 2 has an internal slot 201, and a through-hole screw stabilizer 202 is installed in the internal slot 201. The screw stabilizer 202 axially positions and fixes the internal components of the multi-stage bushing 2 to prevent displacement during use; A first rubber washer 203, an aluminum spacer 204, and a second rubber washer 206 are sequentially fitted onto the screw stabilizer 202. Both the first rubber washer 203 and the second rubber washer 206 have holes whose dimensions match the dimensions of the screw stabilizer 202. This ensures that the rubber washers can effectively buffer external forces, reduce wear, and extend service life. The aluminum spacer 204 further disperses pressure, improving the overall durability and stability of the structure. The aluminum partition 204 is filled with honeycomb material 205, which can effectively absorb vibration and enhance the buffering effect. One end of the screw stabilizer 202 is provided with a fixing nut 207, which is used to press the second rubber washer 206 and its internal components such as the aluminum partition 204, honeycomb material 205 and the first rubber washer 203, to ensure that the components are tightly connected and prevent loosening, thereby further improving the reliability and safety of the overall structure. The fixed shaft 302 is connected to the suspension tube 4. The left and right ends of the suspension tube 4 are fixedly connected to the first suspension tube joint 401 and the second suspension tube joint 402. The first suspension tube joint 401 and the second suspension tube joint 402 can connect the stabilizer 1 and other components to form a flexible and stable support system, ensuring that the stabilizer 1 and the suspension tube 4 work together under complex working conditions. A lifting tube 4 is connected to the fixed shaft 302. Specifically, a first lifting tube joint 401 and a second lifting tube joint 402 are fixedly connected to the left and right ends of the lifting tube 4, respectively. A connecting hole 403 is provided in the middle of the first lifting tube joint 401 and the second lifting tube joint 402. During installation, the connecting hole 403 is fitted onto the fixed shaft 302, so that the lifting tube 4 is rotatably connected to the fixed shaft 302 of the locking mechanism 3 through the first lifting tube joint 401 and the second lifting tube joint 402. The first lifting tube joint 401 and the second lifting tube joint 402 can connect to the stabilizing rod 1 to form a flexible and stable support system, ensuring that the stabilizing rod 1 and the lifting tube 4 work together under complex working conditions. The elastic compression block 305 has a spring post 305a inside, which provides a restoring force to separate the second ratchet 306 from the first ratchet 303. The end of the rotating handle 304 facing the inside of the fixed side plate 301 is provided with a compression block for pushing the elastic compression block 305.

[0016] Working principle: When using this device, the multi-stage bushing 2 is first installed on the left and right ends of the stabilizer 1. The connecting pipe 102 is fixedly connected to the bottom of the multi-stage bushing 2. The internal slot 201 of the multi-stage bushing 2 is provided with a screw stabilizing column 202. The screw stabilizing column 202 tightly fixes the first rubber washer 203, the second rubber washer 206 and the aluminum spacer 204 to ensure that there is no relative displacement between the components. The locking mechanism 3 at the other end of the connecting pipe 102 has a locking function. When the operator rotates the rotary handle 304, the squeezing block on the other side of the rotary handle 304 rotates to the protrusion of the elastic squeezing block 305. Under the action of the protrusion, the elastic squeezing block 305 drives the second ratchet 306 to extend towards the first ratchet 303. After the first ratchet 303 and the second ratchet 306 are engaged, a tight meshing relationship is formed to ensure that the locking mechanism 3 is stable and reliable.

[0017] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
