FIELD: machine building.SUBSTANCE: shock absorber consists of a working cylinder, inside which a piston is installed, and a compensation chamber. The piston is made of two plates having ring-shaped slots to pass damping fluid with a gasket in-between. The slots in the plates are arranged so that the holes can be partially or completely closed at turning of the plates in respect to each other. A rebound valve and a compression valve with springs and weights fixed at the valve heads are installed in the piston. The upper piston plate can be turned in respect to the lower plate. The turn is carried out by the spring rigidly connected to a rod and a bush. In case of ambient air temperature changes, the spring changes its length and turns the upper plate in respect to the lower one. The compensation chamber is fitted by two pistons inside, one of them has a valve, the other one separates the working fluid and inert gas.EFFECT: invention ensures good shock absorbing properties of a car suspension in the wide range of working temperatures and parts of mass fluctuations thus allowing for the decrease of impact loads on the units and load-bearing elements when riding on bumpy roads.2 dwg |
