In the brake system of automobile, brake facing is the breaking piece of most critical, and the quality of all braking effects is all that brake facing plays a decisive role, so the brake facing of agreeing is the patron saint of people and automobile.
Existing brake facing mainly divides following a few class: asbestos brake lining, semi-metallic brake pad, micro-metal brake pad, NAO formula brake facing, ceramic brake, NAO ceramic brake.The principle of work of existing brake facing is mainly carried out self-friction, utilizes the friction of brake facing and brake disc (drum), and the kinetic energy that vehicle is advanced converts the heat energy after friction to, and car is stopped.
The method of traditional friction brake, causes the wearing and tearing of corresponding component, reduction of service life.
Summary of the invention
The present invention proposes a kind of brake system, solved friction brake in prior art and cause the problem of component wear.
Technical scheme of the present invention is achieved in that
A kind of brake system, comprising: the brake pedal sensor being connected with brake pedal, export proportional electric signal according to navigating mate braking strength;
AD converter, is connected to described brake pedal sensor, and analog electrical signal is converted to digital signal;
Controller, receives the digital signal that described AD converter is exported, and exports corresponding control signal by the data sheet prestoring;
Power transformation circuit, its input end is connected to storage battery, its mouth is connected to the first electromagnetism winding and the second electromagnetism winding, arrive described the first electromagnetism winding and the second electromagnetism winding, current opposite in direction in the first electromagnetism winding and the second electromagnetism winding according to the electric current of the control signal control output respective magnitudes of described controller;
Described the first electromagnetism winding is arranged in vehicle drive shaft, forms power generating system with the second electromagnetism winding, and the first electromagnetism winding is rotor-end, and the second electromagnetism winding is stator terminal;
Described power transformation circuit is bi-directional path.
Alternatively, described controller is dsp processor.
Alternatively, described controller is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
By being arranged on the generator system on axle drive shaft, realize magnetic resistance braking, avoid the component wear of traditional brake facing.
Brief description of the drawings
