Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an internal protection monotube shock absorber for a modified vehicle. Background Art

[0002] Shock absorbers are common accessories on vehicles. When a vehicle is driving, the tires will vibrate up and down due to the unevenness of the ground. Therefore, shock absorbers are installed to absorb the vibration caused by the wheels encountering uneven roads and improve riding comfort.

[0003] However, the shock absorber is under long-term stress and needs regular adjustment and maintenance to ensure the best shock absorption effect. The existing shock absorber is generally an integral spring seat, which needs to be completely removed for adjustment, which is very troublesome. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide an internal protection monotube shock absorber for a modified vehicle, which is easy to adjust, disassemble, assemble and maintain.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a modified vehicle interior protection single-tube shock absorber, comprising a cylinder, a piston mechanism is installed in the cylinder, a main seat is provided at one end of the cylinder, and an end cover is provided at the other end of the cylinder, one end of the piston rod of the piston mechanism passes through the end cover and is installed on the spring seat, a piston is installed on the piston rod, and a buffer assembly is provided on the spring tray of the spring seat, the buffer assembly includes spring washers and buffer blocks arranged on both sides of the spring tray, the piston rod passes through the spring washers and buffer blocks on both sides of the spring tray and is fixed by locking nuts, and the suspension spring is installed between the spring washers and the spring frame outside the cylinder.

[0006] In the above technical solution, a piston gasket is installed between the main seat and the cylinder body. The piston gasket extends toward the axis of the cylinder body and can abut against the piston when the piston is at its extreme position.

[0007] In the above technical solution, the piston gasket is made of polytetrafluoroethylene.

[0008] In the above technical solution, a one-way valve is provided on the main seat, and the one-way valve is communicated with the inner cavity of the cylinder.

[0009] In the above technical solution, a sleeve is provided on the outer side of the piston rod, and the spring washer and the buffer block are sleeved on the sleeve.

[0010] In the above technical solution, the piston rod is provided with a guide, and the guide and the piston can move along the inner wall of the cylinder.

[0011] In summary, the technical solution of the utility model has the following beneficial effects compared with the traditional technical means: the utility model optimizes the monotube shock absorber, adjusts the spring seat structure, adds a buffer component, and can adjust the tightness of the suspension spring through the locking nut, which is more convenient for disassembly on the one hand, and also convenient for adjustment when needed on the other hand.

[0012] A gasket is installed between the main seat and the cylinder body, which can effectively protect the piston when the piston reaches the limit position and prevent the piston from hitting the main seat and causing damage. BRIEF DESCRIPTION OF THE DRAWINGS
