Description
Technical Field
The invention relates to the field of automobile brakes, in particular to a reinforcement type line control brake.
Background
The brake-by-wire technology is a novel brake technology appearing in recent years, a brake and a brake pedal do not depend on mechanical or hydraulic connection, a part of or all brake pipelines are replaced by electric wires, and an electric control element is operated by a controller to control the magnitude of braking force, so that the stable and reliable brake control of an automobile is realized. At present, the brake-by-wire system mainly comprises an electronic hydraulic brake system (EHB) and an electronic mechanical brake system (EMB). The brake-by-wire system is beneficial to optimizing the braking performance of the whole vehicle, and can be conveniently integrated with other electronic control systems such as ABS, ASR, ESP and the like, so that the system has wide development space. Especially as a brake system for an unmanned vehicle, is considered to be better by those skilled in the art.
The electronic hydraulic brake system (EHB) is formed by transforming the traditional hydraulic brake system, the braking process is quicker and more stable, the braking safety and the comfort of an automobile are improved, but the electronic hydraulic brake system does not have all the advantages of a complete brake-by-wire system because a hydraulic component is reserved, and is generally regarded as an advanced product of an electronic mechanical brake system (EMB). The original hydraulic pipeline is reserved, and the technical problem of slow brake response caused by long hydraulic pipeline is still not solved. Meanwhile, the brake pipeline can be elastically deformed under the action of high-pressure brake oil, so that the pressure fluctuation of the brake oil in the brake pipeline is caused, and the accurate control of the vehicle brake is greatly influenced.
The technical scheme of the prior electronic mechanical brake system (EMB) is that a motor drives a mechanical mechanism to realize a braking process, so that the structure of the brake system is greatly simplified, and the brake is easier to arrange, assemble and overhaul. The existing electronic mechanical brake system mostly adopts a brake motor and a speed reducing mechanism or a force increasing mechanism as power sources, so that the overall structure size is larger. In the braking process, the braking motor is always in a locked-rotor state, so that the requirement on the performance of the braking motor is high. In order to ensure enough braking torque, the main technical scheme adopted at present is a motor acceleration and deceleration mechanism, but the deceleration mechanism can cause slow braking response and increase the braking distance of a vehicle.
Along with the popularization of new energy vehicles and intelligent vehicles, an electronic mechanical brake system is inevitably widely applied, the problems of high performance indexes and high price of a motor caused by the fact that an EMB installation space and a brake motor are in a locked-rotor state for a long time are solved, and the problem that a deceleration mechanism causes slow brake response is solved urgently.
