Vehicle body suspension system based on pressure principle

Abstract

The invention provides a vehicle body suspension system based on a pressure principle and belongs to the technical field of automobiles. According to the vehicle body suspension system based on the pressure principle, during mounting, telescopic rods of gas springs are connected with hinged supports mounted on wheel rims; bases of the gas springs are mounted on linking discs; connecting lines frommounting points of hinging seats on the wheel rims in an initial state to the centers of wheel axles and connecting lines from mounting points of the gas springs on the linking discs to the centers of the wheel axles have included angles of 45 degrees; in the wheel rotating process, high pressure chambers of the three gas springs intermittently communicate with an upper gas chamber of a sliding ring; when a control system of a vehicle body receives a vehicle body heightening command, a gas chamber under the sliding ring is pressurized by using an air compressor; and therefore, when each spring rotates to a low position of a wheel, a gas chamber valve core of the high pressure gas chamber can be opened, and the high pressure air enters the gas spring so that the gas spring is extended; andmeanwhile, the other two gas springs release pressures during passing through the low pressure gas chamber in a high position of the sliding ring; and the gas springs retract to integrally heighten the vehicle body to help to maintain the stability of the vehicle body.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a car body suspension system based on the air pressure principle. Background technique [0002] At present, oil-pneumatic suspension systems are commonly used in heavy-duty vehicles and construction machinery. The rod chambers and rodless chambers of the oil cylinders suspended on both sides are cross-connected through pipelines to obtain limited suspension anti-roll performance. However, a complete oil-air suspension system is bulky and heavy, and it is difficult to popularize it on family cars. Family cars can only use mechanical springs for shock absorption. In today's pursuit of speed and comfort, the chassis of vehicles is becoming more and more sophisticated. Low, vehicles without oil-air suspension have difficulty off-road. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art and provide a car b...
