Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a damping cylinder rear shock absorber. Background Art

[0002] At present, motorcycle rear shock absorbers generally use steel cylinder damping cylinders, which are generally composed of steel pipes, bases, iron rings, locating keys or locating seat rings and other parts, and are welded into damping cylinder assemblies. Generally, steel cylinder damping cylinders need to be polished and then electroplated, galvanized or electrophoretically painted before assembly to achieve rust prevention and aesthetic requirements.

[0003] The buffer device of the existing automobile shock absorber is generally a single spring sleeved on the outer wall of the cylinder and the piston rod. The external spring is easy to be damaged. If the spring is damaged, continuing to drive without knowing it is likely to cause serious harm to the driver.

[0004] For this reason, we urgently need to provide a damping tube rear shock absorber. Utility Model Content

[0007] An external damping spring is fixedly connected to the outer wall of the aluminum spring seat, and a damping assembly is arranged on the outer wall of the aluminum spring seat.

[0008] As a preferred solution, the shock absorbing assembly includes a first connecting plate fixedly connected to the outer wall of the aluminum spring seat, and an internal shock absorbing spring is fixedly connected to one side of the first connecting plate.

[0009] As a preferred embodiment, one end of the internal shock-absorbing spring is fixedly connected to a second connecting disk, the outer wall of the second connecting disk is fixedly connected to a connecting rod, the outer wall of the connecting rod is slidably connected to a damping cylinder body, and one end of the damping cylinder body is fixedly connected to one end of the sleeve.

[0010] As a preferred solution, a thread groove is formed on the inner wall of the aluminum spring seat, a thread block is threadedly connected to the inner wall of the thread groove, and a top ear is fixedly connected to the outer wall of the thread block.

[0011] As a preferred solution, one end of the buffer rod is fixedly connected to a connecting plate, and the outer wall of the connecting plate is fixedly connected to a sliding block.

[0012] As a preferred solution, a sliding groove is provided on the inner wall of the sleeve, and the inner wall of the sliding groove is slidably connected to the outer wall of the sliding block.

[0013] Compared with the prior art, the utility model provides a damping cylinder rear shock absorber, which has the following beneficial effects:

[0014] 1. The utility model cooperates with the internal shock-absorbing spring, the second connecting plate, the connecting rod and the damping cylinder body. When vibration occurs, the aluminum spring seat will squeeze the external shock-absorbing spring, so that the external shock-absorbing spring drives the buffer rod to move, and the buffer rod drives the connecting plate and the slider to slide on the inner wall of the sleeve to achieve shock absorption. If the external shock-absorbing spring is damaged, the aluminum spring seat will also squeeze the internal shock-absorbing spring, and the internal shock-absorbing spring will drive the second connecting plate and the connecting rod to move, and the connecting rod will slide on the inner wall of the damping cylinder body to complete shock absorption. This achieves the purpose of secondary shock absorption and solves the problem of harm caused by external spring damage.

[0015] 2. The utility model cooperates with the thread groove, the thread block and the top ear. When installation and disassembly are required, the top ear can be grasped and rotated to make the thread block rotate in the thread groove for disassembly, which facilitates installation and disassembly and makes it easy to replace parts when they are damaged, thus meeting people's usage needs.
