Problems solved by technology

[0003] Of course, compared with the traditional suspension, due to the complex structure of the air-type adjustable suspension, the probability and frequency of its failure will be higher than that of the coil spring suspension system. Sealing is also a problem. In addition, if the height of the chassis is adjusted frequently, it may cause local overheating of the air pump system, which will greatly shorten the service life of the air pump.

Abstract

The invention discloses a self-recovery rubber air spring. The self-recovery rubber air spring comprises a column-shaped main body. At least one end of the column-shaped main body is provided with a bent bladder part. Each bent bladder part comprises two or more bent bladder units. The two ends of the inner wall of each bent bladder part are provided with a left protrusion and a right protrusion which are towards the axial center position of the column-shaped main body respectively, and a spring is arranged between the left protrusion and the right protrusion in each bent bladder part. In addition, the springs are in a free state when the rubber air spring works. According to the self-recovery rubber air spring, the structural features are improved, so that the self-recovery capability of the rubber air spring during work is improved; the strength and self-adjusting capability of the rubber air spring is enhanced; the service life is prolonged, and the quality is improved.

Description

technical field [0001] The invention relates to the technical field of rubber air springs, in particular to self-restoring rubber air springs used for anti-swing and shock absorption of 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...
