The invention provides a combined type shockproof inner piston. The combined type shockproof inner piston comprises a piston body. The piston body is divided into an upper surface and a lower surface. The combined type shockproof inner piston is characterized in that the piston body is provided with a center hole, compressing flow guide holes and stretching flow guide holes, the center hole is arranged at the center of the piston body, the compressing flow guide holes are arranged in the upper surface, the stretching flow guide holes are formed in the lower surface, the center hole, the compressing flow guide holes and the stretching flow guide holes all penetrate through the piston body, and the compressing flow guide holes and the stretching flow guide holes are annularly distributed with the center hole as the center. The combined type shockproof inner piston has the beneficial effects that the damping effect can be thoroughly improved, the universality is improved, different kinds of damping are formed, the flow direction and flow of hydraulic oil are regulated, shockproof inner pressure is relieved, and the service life of a seal piece is prolonged; and the combined type shockproof inner piston has the advantages of being simple in structure, low in machining cost and the like.
Description
technical field [0001] The invention belongs to a piston device, in particular to a combined shock-absorbing inner piston. Background technique [0002] At present, the known shock-absorbing inner piston structure is manufactured in batches by simple casting, stamping and mould. It is relatively cost-effective, but in terms of performance, due to the single and small number of oil holes, the distinction between compression and rebound damping is not in place, so that the internal temperature of the shock absorber continues to increase, and the pressure on the seals increases sharply, making the shock absorber prone to oil and air leakage , lose the shock absorbing effect. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a combined shock absorber inner piston, which can improve the damping effect, increase versatility, shape different dampers, relieve the internal pressure of the shock abso...
