VEHICLE HYDROPNEUMATIC SUSPENSION

摘要

FIELD: transport engineering; truck hydropneumatic suspensions. ^ SUBSTANCE: proposed truck hydropneumatic suspension contains hydraulic cylinder with damper connected with pneumatic member provided with pneumatic and hydraulic spaces. Pneumatic member is made in form of pneumatic cylinder with fitted-in piston forming pneumatic space and hydraulic space connected with overpiston space of hydraulic cylinder by flexible pipelines. Pneumatic cylinder has cooling jacket formed by casing. Overpiston and underpistons spaces of hydraulic cylinder are connected with bypass channel in which damper is installed. ^ EFFECT: simple design and compact suspension featuring high elastic characteristics and enlarged operating capabilities. ^ 4 dwg
