Abstract
A brake electromagnetic booster for a new energy automobile comprises a brake pedal, a brake bar, a brake master cylinder, a control chip, a power supply, a detector and an electromagnetic booster. One end of the brake bar is connected with the brake pedal. A piston of the brake master cylinder is connected with other end of the brake bar. The power supply is connected with the control chip so as to have the control chip powered. The detector is arranged on the brake pedal and connected with the control chip through a signal line so as to collect brake information of a driver and feed back the brake information to the control chip. The electromagnetic booster comprises a shell, coils, a magnetic body and a control circuit, wherein the shell is sleeved on the brake bar which can slide along the shell, the coils are fixedly arranged in the shell and connected with the control circuit, the control circuit is connected with the control chip through the signal line, and the magnetic body is fixedly connected on the brake bar and housed in the cavity of the coils. Auxiliary force can be exerted on the brake bar when the driver brakes so as to reduce brake force and improve brake flexibility.
Description
Technical field
The present invention relates to a kind of brake booster, particularly a kind of new-energy automobile brake electromagnetic booster.
Background technology
In the world today, the contradiction of developing the economy with environmental pollution, energy resources are day by day exhausted, environmental pollution is day by day seriously the problem of whole world facing, also be the major issue of Chinese society economic development, seek the alternative energy resources of the conventional energy resourcess such as coal, oil and natural gas, develop the important topic that new forms of energy become society.Automobile is important oil consumption rich and influential family, and the heat efficiency of combustion engine is lower at present, the heat energy that fuel combustion produces approximately only has 35%-40% for actual running car, therefore countries in the world are devoted to develop clean energy-saving automobile one after another, new-energy automobile is constantly developing and with the energy source and power device by new, replaces traditional combustion engine and drive automobile, and therefore traditional vacuum producing in induction maniflod during by engine operation assists the brake booster of brake no longer applicable for new-energy automobile.
For above-mentioned technological deficiency, be still necessary to invent a kind of new-energy automobile brake electromagnetic booster especially.
