Definitions

  • the invention relates to transport engineering, in particular, to shock-absorbing suspension devices and can be used in front and rear shock absorbers with gas back-up for automobiles and in other equipment.
  • the objective of the invention is to increase the operational reliability and durability of the shock absorber due to the preservation of gas pressure inside the shock absorber and to increase the service life of the cuff by eliminating dry friction of the cuff during long-term operation of the shock absorber with a high vibration frequency and low amplitude of the rod’s movement, which occurs when the vehicle moves on high speed.
  • the problem is achieved in that in the method of sealing the shock absorber rod, including sealing the cuff rod according to the invention, liquid baths are created in the shock absorber in which the working edges of the cuff are located, and the outer part of the edges is angled.
  • the technical result is achieved due to the fact that the viscosity and the density of the working fluid is significantly higher than that of the gas and when gas enters or the dissolved gas is released from the liquid, it rises to the upper part of the cavity, which leads to a significant reduction in leakage to a suspension of gas, especially when working in extreme operating conditions.
  • this manufacture of the lower working edge of the cuff its elasticity increases, which prevents the loss of working fluid even with significant wear on the shock absorber.
  • FIG. 1 shows a General view of the sealing assembly of the shock absorber, allowing the implementation of the inventive method.
  • the working edge 1 of the cuff 2 is located in the created bath 3 containing the working fluid, and the outer part 4 of the edge of the cuff 2 is located at an angle that excludes the accumulation of gas bubbles near the working edges and is in the bath with liquid 5 - this creates a hydraulic plug and eliminates the loss of gas pressure even with significant wear on the shock absorber.
  • liquid baths 1 and 2 allow to spread the working edges of the cuff and concentrated gas, which leads to the impossibility of gas loss and the absence of dry friction of the cuff.
  • the application of the proposed method significantly reduces gas leakage from the shock absorber, especially when operating in extreme conditions, which leads to an increase in the stability of its parameters, reliability and durability.
