Abstract

The invention discloses a piston type rubber air suspension assembly for vibration reduction of a vehicle cab. The assembly comprises a bag type body, an end cover, a piston, a vibration reducer and a support rod, wherein the end cover and the piston are respectively connected to the two ends of the bag type body; the vibration reducer coats the internal part of the piston; the support rod coats the internal part of the vibration reducer to slide, and extends to the top position of the end cover; a connecting head is arranged at the outer side, in the top position of the end cover, of the support rod; the piston comprises an insertion end and a free end; the insertion end is inserted in the bag type body; and a connecting head is arranged at the tail end of the free end. The assembly is simple in structure, convenient for manufacturing and easy to realize a process, and improves the phenomenon of shorter service life and local heating of a rubber airbag caused by excessive deformation and strain due to frequent use of a rubber air spring in the use process, so that the service life of the rubber air spring is prolonged, and the quality of the rubber air spring is enhanced.

Description

technical field [0001] The invention relates to the technical field of air suspension, in particular to a piston-type rubber air suspension assembly for vehicle cab shock absorption. Background technique [0002] Now with the development of vehicles, rubber air springs are widely used in trucks, off-road vehicles and SUV off-road vehicles, buses, high-speed rail, etc., for air suspension systems, air shock absorption systems, and heavy trucks. The rate exceeds 80%, and it has been 100% used in high-speed buses and luxury city buses, and some cars have also installed this system. Air rubber spring suspension models will have ground clearance sensors near the front and rear wheels. According to the output signal of the ground clearance sensor, the trip computer will judge the height change of the vehicle body, and then control the air compressor and exhaust valve. The spring is automatically compressed or extended to reduce or increase the ground clearance of the chassis to i...
