FIELD: transport engineering. SUBSTANCE: invention relates to pneumohydraulic suspensions of vehicles. Proposed suspension contains pneumohydraulic spring with main cylinder 1 accommodating piston 3 with hollow rod 4 forming pneumatic space 2 and hydraulic space 7 in main cylinder 1, accumulator with additional cylinder 9 mounted on main cylinder 1 and connected with spring pneumatic 2 through valve element. Value element is made in form of spring-loaded plunger 13 installed in axial hole 14 of housing 12 mounted in additional cylinder 9. spring-loaded plunger forms, together with housing 12, underplunger space 15 communicating with pneumatic space 2 of spring and overplunger space 16 communicating with underplunger space 15 through axial throttling hole 17 in plunger 13. Throttling channel 18 made in housing 12 of valve element connected space 10 of additional cylinder 9 with pneumatic space 2 of spring, and radial channel 19 also made in housing 12 and closed by plunger 13 connects pneumatic space 2 of spring with space 10 of additional cylinder 9 through axial hole 14 if final pressure in pneumatic space of spring at end of compression stroke caused by temperature rise exceeds designed value. EFFECT: improved smoothness of running, provision of simple, compact and reliable design. 1 dwg
