Problems solved by technology

[0005] After in-depth analysis, it is found that in many cases, the deceleration of the car body does not require a strong braking force. In these cases, the use of brake pads to participate in braking will undoubtedly increase the wear of the brake pads, and the recovery rate of kinetic energy during the deceleration stage of the car body is also low.

Embodiment Construction

[0018] This embodiment includes a brake pedal mechanism, a power generation brake device and a mechanical brake device, the brake pedal mechanism has a braking stroke section, and the brake pedal mechanism also has a free travel mechanism before the brake stroke section, in the free stroke mechanism There is a stroke sensor, the signal output end of the stroke sensor is connected to the control end of a switch circuit, and the switch circuit is connected in series between the generator stator coil of the generator braking device and the corresponding load, when only the free travel mechanism acts on the brake pedal , the generator braking device works and the mechanical brake device does not work; when the brake pedal is in the braking stroke section, the generator brake device and the mechanical brake device work simultaneously.

[0019] like figure 1 As shown, the generator braking device includes a generator 7, a rectification circuit 8, a power switch 9, a voltage stabiliz...

Abstract

The invention relates to a vehicle body braking electrical power generating system, comprising a brake paddle mechanism provided with a brake stroke segment, a power generation braking device and a mechanical braking device. The system is characterized in that the brake paddle mechanism is also provided with a free stroke mechanism in front of the brake stroke segment; a stroke sensor is arranged in the free stroke mechanism; the signal output end of the stroke sensor is connected to the control end of a switch circuit which is connected between the stator coil of a generator of the power generation braking device and a corresponding load in series, thereby further reducing abrasion on a brake sheet in the braking process and improving the kinetic energy use ratio at the decelerating process of the vehicle body.

Description

technical field [0001] The invention relates to a vehicle body braking system, in particular to a vehicle body braking power generation system. Background technique [0002] At present, motorcycles, automobiles, etc. have become people's daily means of transportation. The conventional braking device basically adopts the method of brake pad friction braking, which has strong braking force and good reliability. However, in many cases, such as when the vehicle goes downhill At this time, the driver must slow down and brake. If the slope is long, the brake will heat up violently due to being in a friction state for a long time. In addition, the brake is used for a long time, and the wear and tear is relatively large, which reduces the service life. [0003] With electric motorcycles, electric cars and other electric vehicles gradually entering people's lives, the battery life of electric vehicles has become an important factor restricting the popularity of electric vehicles. Th...
