The invention provides a novel damping adjusting unit. The novel damping adjusting unit comprises a valve seat, an adjusting screw connected through the valve seat and a spring sleeving the adjustingscrew as well as a stop nut and a locking nut suitable for a stop spring, wherein one end of the valve seat of the novel damping adjusting unit is connected to a valve block sealed to the screw and the end surface of the valve seat; the valve block divides the inner and outer sides of the valve seat into inner and outer cavities; a compensating valve sleeve connected and fixed to the inner wall ofthe valve seat is arranged in the inner cavity and is suitable for controlling throttling according to a circulating area thereof so as to change the adjusting range of the damping force. According to the scheme, the damping force can be adjusted, the adjusting range can be changed, and a modular design can be formed. The invention also provides an oil pressure shock absorber based on the novel damping adjusting unit.
Description
technical field [0001] The invention relates to a novel damping adjustment unit, in particular to a damping adjustment unit suitable for oil pressure shock absorbers of various vehicles such as locomotives, urban rails, subways, EMUs, automobiles and engineering. Background technique [0002] Oil shock absorber is an important part of various vehicles, and its damping characteristics directly affect the safety, stability and comfort of vehicle operation. As the adjustment structure of the damping force of the hydraulic shock absorber, the damping adjustment unit is directly related to whether the shock absorber can meet the damping characteristics required by the performance. [0003] In the prior art, the damping adjustment unit can only control the damping force only by changing the stiffness of the spring and the preload of the spring, and its adjustment range is limited and cannot be designed in a modular manner. In order to solve the above problems, it is necessary to ...
