Shock absorption rubber air spring used for vehicle

Abstract

The invention discloses a shock absorption rubber air spring used for a vehicle. The shock absorption rubber air spring comprises a bladder type main body, an upper shock absorption part and a lower shock absorption part. The upper shock absorption part and the lower shock absorption part are connected with the two ends of the bladder type main body respectively. In addition, the upper shock absorption part comprises an upper shock absorption pillar and a buffer part. The shock absorption pillar is fixedly connected with the top of the buffer part, and the buffer part is in the shape of a bottle without bottoms at the two ends. The upper end of the buffer part is connected with the bottom of the shock absorption pillar. The lower end of the buffer part is inserted into the bladder type main body. The upper shock absorption part is made of vulcanite. The buffer part of the upper shock absorption part further comprises a conical transition part, an annular connection part and an insertion part. The conical transition part is connected with the shock absorption pillar. The insertion part is inserted into the bladder type main body. The annular connection part is located between the conical transition part and the insertion part. According to the shock absorption rubber air spring, the phenomena of the short service life and partial heating of the rubber air spring caused by excessive deformation and overstrain of a rubber airbag due to frequent use in the using process are avoided, so that the service life of the rubber air spring is prolonged, and the quality of the rubber air spring is improved.

Description

technical field [0001] The invention relates to the technical field of rubber air springs, in particular to shock-absorbing rubber air springs for vehicles. 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 increase the stability of t...
