Problems solved by technology

The manufacturing cost of the linear motor energy-feeding suspension is high, and the efficiency of the linear motor is very low compared with the rotary motor; the rack-and-pinion and ball screw type energy-feeding suspensions are low in cost, but the frequent positive and negative commutation of the rotary motor cannot be avoided , the recovered energy is less; the structure of the hydraulic electric energy-feeding suspension is reliable, and the cost is low. Good guarantee of the dynamic characteristics of the vehicle itself

Abstract

The invention relates to an energy-regenerative suspension for a car and a control method thereof, pertaining to the research field of car suspensions. The suspension comprises a hydraulic mechanism, a driving device, a rotary motor and a battery storage mechanism. The driving device helps simplify the system structure. Power of two motors of the hydraulic mechanism is integrated to a same output end. Only one motor is used so that cost is lowered. An energy-regenerative hydraulic pipeline is used for interconnecting upper and lower cavities of two hydraulic cylinders reversely so that operation stability is improved without affecting smoothness of car driving. Energy of reciprocating oil liquid can be recovered and converted to be electric energy for electric equipment. The energy-regenerative suspension for the car and the control method thereof have following beneficial effects: the car is easily operated; vibration energy of the suspension is recovered; and the suspension has a broad usage prospect.

Description

technical field [0001] The invention belongs to the field of vehicle suspension research, and in particular relates to a vehicle energy-feeding suspension and a control method thereof. Background technique [0002] Environmental pollution and energy crisis pose severe challenges to the development of the automobile industry. How to improve the performance of automobiles while reducing energy consumption has become the focus of research in the automobile industry in recent years. [0003] The vibration energy of the traditional suspension is usually dissipated in the form of heat through the damper, resulting in a great waste, and the energy-feeding suspension can recycle this part, which is energy-saving and environmentally friendly. The common energy-feeding suspension forms are: linear motor type, rack and pinion type, ball screw type and hydraulic type. The manufacturing cost of the linear motor type energy-feed suspension is high, and the efficiency of the linear motor ...
