FIELD: transport engineering.
SUBSTANCE: invention relates to hydraulic shock absorber struts of vehicle suspensions, particularly, to devices providing their adjustment, stabilizing of characteristics of suspension shock absorber struts at ambient temperature fluctuations within +40°C and -40°C. Proposed hydraulic shock absorber contains hydraulic cylinder with working medium, piston and rod. Piston and rod spaces are connected by channels made in piston and additional channel made in rod. Capacity of additional channel is made adjustable depending on temperature of working medium by means of rotary bushing with hole and spring made of bimetal or material with memorized shape effect and rigidly connected by one end with rod and by other end with adjusting bushing.
EFFECT: provision of hydraulic strut of front suspension of VAZ car with constant characteristics at any temperature of ambient air which is important in winter.
