SINGLE-TUBE SHOCK ABSORBER Russian patent published in 2005 - IPC

FIELD: transport engineering; suspensions of vehicles.

SUBSTANCE: proposed single-tube shock absorber contains housing with hydraulic space filled with working fluid, guide bushing, rod and piston stationary installed on rod and dividing hydraulic space into upper and lower parts. Hollow compensator made of elastic material is installed in lower part of hydraulic space. Constant head of compensator is realized owing to elasticity of compensator, or its constant force action onto working fluid in hydraulic space are preset in process of assembling of shock absorber. Volume of compensator is reduced by value equal to increase of volume of part of rod located in hydraulic space of shock absorber.

EFFECT: improved reliability and sensitivity of shock absorber.
