Problems solved by technology

However, the existing semi-active suspension mainly changes the damping coefficient of the suspension, and the semi-active suspension with variable stiffness is also limited to the application of air suspension or oil-pneumatic suspension.

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] In the variable stiffness electromagnetic energy-feed suspension of the embodiment of the present invention, the upper lifting lug 1 is welded on the motor cover 3 and connected with the sprung mass 300 , and the lower lifting lug 2 is welded on the stator base 5 and connected with the unsprung mass 400 . The motor fixing plate 4 is stepped in the axial direction, wherein the cross-section of the end with a larger diameter is cylindrical, and is threaded along the outer wall, and is connected with the inner wall of the motor cover 3 by threads, and the cross-section of the end with a smaller diameter is a square. To facilitate the installation of the motor fixing plate 4. At the same time, the motor fixing plate 4 is evenly distributed with four axial stepped light holes for fixing the stepping motor, and a th...

Abstract

The invention relates to a stiffness-variable electromagnetic energy feedback suspension, and belongs to the technical field of novel suspensions of vehicles. The stiffness-variable electromagnetic energy feedback suspension comprises an upper hanging lug, a lower hanging lug, a motor shield, a motor fixing plate, an upper bracket, a middle bracket, a lower bracket, a spring A, a spring B, a stator base, a damping-adjustable device and an energy feedback device. A piston rod is fixed with a sprung mass through the motor fixing plate, the motor shield and the upper hanging lug; a stator is fixed with an unsprung mass through the stator base and the lower hanging lug; the spring A is in parallel connection with the damping-adjustable device; the stiffness characteristics of a system can changed by adjusting the opening of a throttle hole in the damping-adjustable device; the energy feedback device comprises the stator, an armature winding and a permanent magnet; when the suspension vibrates, the energy feedback device is driven to generate electricity, vibration energy is converted to electrical energy, and energy recovery is achieved.

Description

technical field [0001] The invention relates to a variable stiffness electromagnetic energy feed suspension, which belongs to the technical field of new vehicle suspensions. 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 optimal only under specific 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] Semi-active suspension and active suspension can improve the performance of the car, but active suspension needs to consume a lot of energy, which limits its practical eng...
