A Single-tube Damping Adjustable Hybrid Suspension Actuator

Abstract

The invention relates to a single-tube-type damping-adjustable hybrid suspension actuator, and belongs to the technical field of novel vehicle suspensions. According to the single-tube-type damping-adjustable hybrid suspension actuator, an energy-feeding device and a damping adjustment device are integrated on a single-tube-type hydraulic damper, wherein the energy-feeding device comprises a stator, an armature winding and a permanent magnet, and can recover the vibration energy of a suspension or actively control the suspension, so that control requirements on a suspension system in complex conditions can be met; and the damping adjustment device can adjust the damping force of the actuator by changing the relative positions of a valve body and a valve core, so that the activation force of the energy-feeding device can be adjusted. Therefore, vibration energy is recovered to the most extent when the suspension is in a passive or semi-active state, and energy consumption is reduced to the most extent when the suspension is in an active state.

Description

technical field [0001] The invention belongs to the technical field of new vehicle suspensions, and in particular relates to a single-tube damping adjustable hybrid suspension actuator. Background technique [0002] Traditional passive suspension parameters are difficult to change once selected. Therefore, in the design process, we can only find an optimal compromise to determine the parameters. That is to say, the performance of the vehicle is the best only under certain working conditions. Once the driving conditions of the vehicle change (such as road conditions and changes in acceleration, braking, steering, etc.) will get worse. Therefore, the traditional passive suspension cannot meet the requirements of comfort and safety at the same time, which limits the further improvement of vehicle performance. [0003] Active suspension can meet the comfort and handling requirements of the car under different working conditions, but active suspension needs to consume a lot of...

Therefore, the traditional passive suspension cannot meet the requirements of comfort and safety at the same time, which limits the further improvement of vehicle performance

[0003] Active suspension can meet the comfort and handling requirements of the car under different working conditions, but active suspension needs to consume a lot of energy, which limits its engineering practicality

At the same time, the actuator of the active suspension is also an important factor limiting its commercial application. At present, the electromagnetic linear actuator has attracted the attention of scholars and researchers in the automotive industry due to its advantages of fast response, no intermediate motion conversion mechanism, and high efficiency. , but its small capacity and low peak thrust cannot meet the requirements of the vehicle for the vibration isolation force of the suspension system under all working conditions
