Problems solved by technology

At present, the energy-feeding suspension can be divided into mechanical type and electromagnetic type according to its principle. Because the mechanism structure of the energy conversion device of the two is too complicated, the energy recovery efficiency is low, and the cost is high, so the application is not very wide

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with specific examples

[0013] figure 1 The mechanism schematic diagram of the new-type less-freedom parallel mechanism energy-feeding suspension system mainly includes vehicle-use energy-feeding composed of a less-degree-of-freedom parallel mechanism, a rotating ultrasonic motor (9), a supercapacitor (8) and a storage battery (7). Suspension, the said few-degree-of-freedom parallel mechanism is made up of end effector platform (1), rotary moving platform (12) and three identical branch chains (4), (13), (15); end effector platform (1) and The rotating moving platforms (12) are all equilateral triangles, and the two platforms are parallel to each other, and their central axes are on a straight line; the three branch chains (4), (13), and (15) all pass through the spherical joint pair (3) and the spherical joint The pair (6) is hinged to the end effector platform (1) and the rotating moving platform...

Abstract

The invention belongs to the automobile conservation technology and the novel suspension field, and in particular relates to an automobile suspension vibration energy regeneration system. The novel energy reclaiming suspension system comprises a lower-mobility parallel mechanism, a rotary ultrasonic motor, a super capacitor and a storage battery. The novel energy reclaiming suspension system can convert vertical vibration of the automobile suspension into rotary movement of the rotary ultrasonic motor by the lower-mobility parallel mechanism, and the rotary movement makes the surface of a piezoelectric disk of the ultrasonic motor be deformed under the action of the friction to generate electrical energy. The system has simple structure, high rigidity, high sensitivity and high energy conversion efficiency, and can effectively achieve the suspension vibration energy recovery.

Description

technical field [0001] The invention belongs to the field of automobile energy-saving technology and novel suspension, and mainly relates to a vibration energy regeneration system of automobile suspension technical background [0002] Suspension is the general term for all force transmission connection devices between the car frame and the axle. The spring stiffness and damping coefficient of the shock absorber of the passive suspension commonly used in automobiles are not adjustable, and cannot be changed at any time with changes in external road conditions. The vibration effect is limited, and most of the vibration energy is dissipated in the form of heat energy. [0003] In order to effectively utilize the energy generated by the vibration of the automobile suspension, energy-feeding suspensions have been proposed. Energy-feeding suspension refers to a new type of suspension system that uses energy recovery devices instead of traditional shock absorbers to recycle the e...
