Compression hydraulic buffer structure

Abstract

The invention discloses a compression hydraulic buffer structure, and belongs to the technical field of shock absorbers, a plurality of groups of compression holes with different depths are formed in a hydraulic buffer assembly, so that compression buffer can be performed when impact force is encountered, and oil can pass through different combinations of holes to be changed into single holes from original multi-holes, so that the impact force is reduced, and the service life of the hydraulic buffer assembly is prolonged. Different from an existing shock absorber adopting an external buffer block structure, the shock absorber can provide a larger supporting force value interval and smoother force value transition, meanwhile, the mode that a supporting ring is embedded in a compression hole is adopted, when the oil temperature rises, an internal thermal expansion rod can be heated to expand, so that an external expansion section is jacked open to expand, and the shock absorption effect is improved. Compared with an existing shock absorber, the large-impact shock absorber has the advantage that the shock absorption and buffering effect under the large-impact working condition can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a compression hydraulic buffer structure. Background technique [0002] The shock absorber is used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. It is widely used in automobiles to accelerate the attenuation of frame and body vibrations and improve the ride comfort of automobiles. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. [0003] Existing shock absorbers usually adopt a single-piston structure. The main problem with this type of structure is that after the configuration of the piston valve system is determined, the damping coefficient cannot be changed. When the road conditions change, the performance of the shock absorber cannot be adjusted ...

Problems solved by technology

[0003] Existing shock absorbers usually adopt a single-piston structure. The main problem with this type of structure is that after the configuration of the piston valve system is determined, the damping coefficient cannot be changed. When the road conditions change, the performance of the shock absorber cannot be adjusted accordingly. To deal with it, provide the necessary damping force demand, and the job of the shock absorber is to convert kinetic energy into heat energy, so after high-intensity work, the temperature of the oil will rise. As we all know, the viscosity of the oil will increase with the temperature The same is true for the oil in the shock absorber, so when the temperature rises, the damping will actually become smaller, which will seriously reduce the shock absorption performance.
