Description

Technical Field

[0001] The utility model relates to the technical field of bushings, in particular to a bushing for an automobile control arm. Background Art

[0002] The automobile control arm (also known as the swing arm) is a key component in the suspension system. It transmits various forces acting on the wheels to the body, while ensuring that the wheels move along a certain trajectory. The connection method of the control arm is generally achieved through a bushing. The automobile control arm bushing is an important component of the automobile suspension system. It connects the wheels and the body of the car and plays an important guiding and force transmission role. The automobile control arm bushing has a rubber sleeve between the outer sleeve and the inner sleeve. The ends of the rubber sleeve are exposed to the outside for a long time, which accelerates the aging of the rubber sleeve and reduces the service life of the rubber sleeve.

[0003] China Utility Model Announcement No.: CN220500424U includes an outer sleeve and a mounting mechanism, the outer side of the outer sleeve is fixedly connected to a limiting ring, the upper end of the outer sleeve contacts a sealing gasket, the sealing gasket is fixedly connected to a pad, the pad is in contact with the limiting ring, the limiting ring is provided with a mounting mechanism, the upper end of the sealing gasket is provided with an inner sleeve, and the outer side of the outer sleeve is connected to a connecting threaded sleeve through a threaded connection. This utility model designs components such as a latch, a bayonet, a spring, and a sleeve, and moves the bayonet by pulling the pull block, and then slides the latch into the limiting ring, and then releases the pull block. Under the elastic action of the spring, the bayonet moves, and then the bayonet slides into the latch, and the installation of the sealing gasket is completed at this time. This installation method does not require the use of a screw rotating tool, and the installation of the sealing gasket can be completed by only pulling the pull block.

[0004] The applicant found that this patent had some shortcomings in use: the pin was inserted into the latch through the restoring deformation force of the spring to fix the gasket. Although no tools were required to turn the screws, the spring might be deformed due to the large bumps and vibrations during driving, causing the pin to separate from the latch, which could easily cause the gasket to fall off and be unstable.

[0005] Therefore, the utility model designs an automobile control arm bushing to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the utility model is to provide a vehicle control arm bushing to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle control arm bushing, comprising: an outer sleeve, the inner wall and the inner middle of the outer sleeve are respectively provided with a rubber sleeve and an inner sleeve, a limiting ring is installed above the outer wall of the outer sleeve, a slot is provided at the top of the limiting ring, an internal thread is provided on the inner wall of the slot, a fixing ring is provided in the slot, an external thread is provided on the outer wall of the fixing ring, a sealing gasket is fixedly installed on the inner wall of the fixing ring, the sealing gasket is slidably connected to the inner sleeve, and a rotating rod is installed on the top of the fixing ring.

[0008] Preferably, an external thread 2 is provided in the middle of the outer wall of the outer sleeve, a fastening ring is provided on the outer side of the outer sleeve, and an internal thread 2 is provided on the inner wall of the fastening ring. When installing the outer sleeve, the outer sleeve is first embedded in the sleeve hole of the control arm, and the fastening ring 12 is turned in from the bottom of the outer sleeve. The fastening ring is fixed by the external thread 2 and the internal thread 2, and the fastening ring is pressed against the bottom of the sleeve hole of the control arm to achieve reinforcement of the outer sleeve 1.

[0009] Preferably, a latch is installed on the outer side wall of the fastening ring. When the fastening ring is screwed to the end, it becomes difficult to screw after contacting the bottom of the control arm. You can pinch the latch and continue to screw it to improve the reinforcement effect of the fastening ring.

[0010] Preferably, the surfaces of the latch and the rotating rod are both provided with a rubber layer, and the rubber layer is made of rubber, which can improve the grip of the rotating rod by the staff.

[0011] Preferably, the surface of the fastening ring is provided with a cotton layer, and the cotton layer is sponge, which can improve the comfort of the staff when rotating the fastening ring.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model uses a rotating rod, which is pinched and rotated by the staff. The fixing ring and the sealing gasket can be rotated and installed in the slot of the limit ring through the external thread 1 and the internal thread 1, so that the sealing gasket can cover the rubber sleeve, which can increase the service life of the rubber sleeve. The threaded installation method is more stable, and the sealing gasket is not likely to fall off due to the bumps and vibrations of the vehicle. Moreover, through the rotating rod, the staff does not need to use tools to turn the screws. BRIEF DESCRIPTION OF THE DRAWINGS
