An active suspension using rubber springs

Abstract

The invention discloses an active suspension using a rubber spring in the field of vehicle suspension. The lower end of the inner cylinder of the active force actuator protrudes downwards out of the outer cylinder and is fixedly connected with a rubber spring coaxially. The uppermost part of the rubber spring is a rigid upper Bottom plate, the bottom is the rigid bottom plate, between the rigid upper bottom plate and the rigid bottom plate, there are rubber main springs and rigid partitions, the lower surface of the rubber main spring is close to the upper surface of the rigid lower bottom plate, and the upper surface supports the rigid partition, the rigidity There is a gap between the partition plate and the rigid upper bottom plate; there is an arc-shaped groove in the middle of the upper surface of the rubber main spring, and the rigid inner tubes arranged at the front and rear pass through the arc-shaped groove, and the front and rear ends are fixedly connected to the upper end of the inner tube mounting seat , the lower end of the inner tube mounting seat is rigidly connected to the lower wishbone, and the lower wishbone is connected between the body and the wheel; the suspension not only has the first-level vibration damping function formed by the active force actuator and the coil spring, but also has a rubber spring. The second level of vibration reduction function.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension, in particular to an active suspension using rubber springs. Background technique [0002] Suspension is the general term for the force transmission connection device between the frame (or load-bearing body) and the axle (or wheel) of the vehicle. Its function is to transmit the force and moment acting between the wheel and the frame, and the buffer The impact force transmitted to the frame or body by the uneven road surface, and attenuates the vibration caused by it, so as to ensure the smooth running of the car. [0003] The active force actuator is a key component of the vehicle's active suspension. The active force actuator has the ability to provide active control force to the suspension and has the potential to make the car obtain a good ride comfort. At present, active power actuators include hydrostatic type, pneumatic type, linear motor type, ball screw-rotary motor type, hydr...

AI Technical Summary

Problems solved by technology

[0004] The invention aims at the problem that the ideal control force of the suspension is amplified due to the large equivalent inertial mass of the existing suspension using a rotating motor type active force actuator, and proposes an active suspension with a rubber spring. The active force actuator is fixed and connected in series with a rubber spring with vibration-damping function concentrically, which effectively eliminates the influence of equivalent inertial mass on the ideal control force
