An inflatable hydraulic electric energy-feeding suspension

Abstract

The invention provides an inflatable hydraulic-electrical energy regeneration suspension. The inflatable hydraulic-electrical energy regeneration suspension comprises a first spring and an energy regeneration damper. The energy regeneration damper comprises a damping mechanism, a first elastic film, an oil and gas chamber, a second elastic film and an energy regeneration circuit. The damping mechanism and the first spring are connected in parallel to a frame and an axle, and the first elastic film is disposed in a rodless cavity of the damping mechanism to divide the rodless cavity into an upper half zone and a lower half zone. The second elastic film is disposed in the oil and gas chamber and divides a cavity of the oil and gas chamber into an oil cavity and a gas cavity. Oil is arrangedin a rod cavity, the upper half zone of the rodless cavity and the oil cavity, inert gas is arranged in the rodless cavity and the gas cavity, the oil cavity communicates with the rod cavity, the gascavity communicates with the lower half zone of the rodless cavity, and the energy regeneration circuit communicates with the oil cavity to form a circuit. The inflatable hydraulic-electrical energy regeneration suspension can overcome the defects of a traditional hydraulic-electrical energy regeneration suspension in energy regeneration efficiency, suspension damping and wheel ground adhesion, further reduces abnormal suspension noise and prevents cavitation in the suspension hydraulic circuit.

Description

technical field [0001] The invention relates to the field of vehicle energy recovery, in particular to an inflatable hydraulic-electric energy-feeding suspension. Background technique [0002] As the most convenient personal means of transportation, automobiles have been popularized all over the world, and the production and sales volume is increasing every year. However, while it brings convenience to people, it also produces a series of problems, among which the energy problem is one of the main problems. By the end of 2017, the number of cars in the world has reached one billion, and behind such a huge number of cars is the consumption of countless fossil energy. In recent years, with the increasing energy shortage, low-energy-consumption and renewable energy vehicles have gradually entered the public's field of vision. Various countries and regions have attached great importance to the research and development of automotive energy-saving core technologies. How to seize ...

Problems solved by technology

However, the traditional hydraulic-electric energy-feed suspension is completely composed of oil, which has a high density and a slow flow rate. When the vehicle is subjected to large vibrations, the energy-feed circuit cannot provide sufficient damping force in real time, which will affect the vehicle. smoothness

In addition, under high-frequency vibration conditions, traditional hydraulic-electric energy-fed suspensions will have a certain probability of cavitation in the hydraulic circuit, thereby reducing the grounding performance of the tires.
