A damping automobile suspension based on double wishbone arms

Abstract

A damping automobile suspension based on double wishbone arms is disclosed and includes an upper connecting plate, an installing axle, a frame, a first swing arm, a second swing arm, a connecting axle, wheels, a hydraulic shock absorber, a damping spring, upper and lower wishbone arms. The inner side of the upper connecting plate is provided with the frame, the right side of the frame is connectedwith the first swing arm and the second swing arm through the connecting axle. The right parts of the first swing arm and the second swing arm are connected with the installing axle, and the exteriorof the installing axle is provided with wheels. The hydraulic shock absorber and the damping spring are connected and distributed between the upper connecting plate and the installing axle. A pressure sensor is electrically connected between the hydraulic shock absorber and the damping spring. The suspension has high-efficient and stable support, and tires do not tilt, thus improving shock absorbing performance of automobile support, making an automobile stabler, reducing vibration feeling of automobile efficiently, achieving good effect, and intelligently monitoring real-time change of vibration pressure. The suspension is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to an automobile suspension based on double-wishbone shock absorption. Background technique [0002] Double-wishbone suspension is also called double-A-arm independent suspension. The double-wishbone suspension has two upper and lower wishbone. The lateral force is absorbed by the two wishbone at the same time. The pillar only bears the weight of the body, so the lateral stiffness is large. The upper and lower A-shaped wishbones of the double-wishbone suspension can precisely position various parameters of the front wheels. Lateral stiffness is greater, so there is less roll in corners. The double-wishbone suspension usually adopts wishbones of unequal length up and down (upper short and lower long), so that the camber angle can be automatically changed when the wheel moves up and down, and the wheelbase change can be reduced to reduce tire wear, and it can adapt to t...

AI Technical Summary

Problems solved by technology

[0003] The stability performance of the existing double-wishbone car suspension is still low. Long-term driving will cause tire wear, the connection and installation will not be fastened, and the shock absorption performance will be low. The bumpy road may cause damage to the suspension and greater vibration of the vehicle body. The service life is shortened, and the vibration pressure is high, it cannot be monitored intelligently, and the safety factor is low, so it is difficult to meet the needs of the existing double-wishbone shock-absorbing automobile suspension
