Distributed damping supporting device of automobile range extender and control method of distributed damping supporting device

Abstract

The invention provides a distributed damping supporting device of an automobile range extender. The distributed damping supporting device comprises a damping supporting device body and a control system, wherein the damping supporting device body comprises a shell and a piston device, an oil chamber and a jacking pillar cavity which communicate with each other are formed in the shell, the piston device is coaxially matched with the oil chamber, a twisting device enabling the piston device to move up and down in the oil chamber is arranged on the shell, a jacking pillar which is in clearance fitwith the jacking pillar cavity is arranged in the jacking pillar cavity, the piston device is used for adjusting the position of the jacking pillar, and the control system is used for supplying oil and discharging oil for the damping supporting device body, and is used for controlling the twisting device to lift the jacking pillar. According to the distributed damping supporting device, the costfor automobile development is lowered, the control system of the damping device is designed, and the damping device achieves a good damping effect while having high universality.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicle equipment, and in particular relates to a distributed damping support device of a vehicle range extender and a control method thereof. Background technique [0002] While improving human life, automobiles have caused a significant increase in traffic energy consumption and aggravated urban smog. Series hybrid electric vehicles, as a stable and transitional model of pure electric vehicles, have become more and more popular due to their advantages such as high efficiency and long cruising range. Having attention. The range extender is a key component of a series hybrid electric vehicle, mainly including an engine, a generator, a drive motor, a fuel tank, an engine controller and a generator controller. [0003] Series electric vehicles have particularly high requirements for the assembly line manufacturing process of the whole vehicle. Compared with pure electric vehicles, the bigg...

AI Technical Summary

Problems solved by technology

[0005] 1. The research and development cost of series hybrid electric vehicles is high, and the traditional fuel vehicle platform cannot be reasonably compatible with the layout of various components, so a new platform development is required;

[0006] 2. The shock absorbing device is a purely mechanical or hydraulic device, without a control system, and has poor self-adjustment performance;

[0007] 3. The versatility of the shock absorber is poor;

[0008] 4. The shock absorption effect is not good
