Energy-absorbing automobile engine suspension

Abstract

The invention discloses an energy-absorbing automobile engine suspension. One end of the energy-absorbing automobile engine suspension is fixedly connected to the engine damping block on an automobilechassis through a mounting buckle, and the other end of the energy-absorbing automobile engine suspension is fixedly connected to an automobile engine through a mounting buckle. The energy-absorbingautomobile engine suspension comprises the mounting buckles, a shell, a spiral steel wire rope damper, a hydraulic damper and a magneto-rheological damper, the magneto-rheological damper further comprises a piston, a high magnetizer, an exciter coil, an annular magnet and a resistive ring and the like, the hydraulic damper further comprises a hydraulic cylinder, an oil storage tank and a damping control valve and the like, and the spiral steel wire rope damper further comprises a limiting plate, a spiral steel wire rope and a guiding rod and the like. Compared with a traditional hydraulic suspension, the energy-absorbing automobile engine suspension further has the advantage of active suspension, and self damping and stiffness can be changed according to the engine vibration changes so asto meet damping and noise reduction requirements of an automobile under the multiple conditions of the wide broadband as the energy-absorbing automobile engine suspension ingeniously connects the spiral steel wire rope damper, the hydraulic damper and the magneto-rheological damper in parallel to form an active suspension system.

Description

technical field [0001] The invention relates to an automobile engine suspension assembly, which is used to prevent the vibration of the automobile engine from being transmitted to the vehicle frame, and belongs to the field of automobiles. Background technique [0002] With the development of the economy and the continuous improvement of the road traffic environment, as well as the increasingly prominent problems of energy and pollution, the design of the car is developing in the direction of high torque and light weight, which greatly deteriorates the vibration characteristics of the car and seriously affect the ride comfort of the vehicle. A large number of studies and experiments have shown that the vibration of the automobile engine is one of the important factors that affect the ride comfort and handling stability of the automobile, as well as the fatigue life of automobile parts. Excessive vibration will accelerate the fatigue damage of parts and reduce the working li...
