Preferably, the brake boosting system comprises a boosting oil cylinder, a pull rod is fixedly connected to the boosting oil cylinder, a first support arm is hinged to the free end of the pull rod, the first support arm is fixedly connected to one end of a sleeve, a second support arm is fixedly connected to the other end of the sleeve, the free end of the second support arm is hinged to one end of the active brake oil cylinder, and the other end of the active brake oil cylinder is hinged to the brake pedal; the sleeve is rotationally sleeved on the supporting shaft, the supporting shaft is arranged through a fixed support, and an angular displacement sensor is arranged at one end of the supporting shaft. The brake boosting system pulls the first support arm to rotate through the pull rod, the second support arm and the first support arm form synchronous rotation through the sleeve, then the brake pedal is pulled to act through the active brake oil cylinder to form brake boosting, at the moment, the active brake oil cylinder can not act, and only a rigid connecting rod component is formed; when the control system receives an active braking signal, the active braking oil cylinder pulls a brake pedal to act; at the moment, if the power-assisted oil cylinder keeps not to act, the active braking is implemented only by the active braking oil cylinder; if the power-assisted cylinder performs power-assisted braking, the braking strokes of the power-assisted cylinder and the power-assisted cylinder are overlapped, so that an accelerating braking effect is formed.
Further preferably, a linear displacement sensor is arranged between the brake pedal and the support. When a driver steps on a brake pedal, a brake signal is sent out, so that a power-assisted system is started to achieve the purpose of brake power assistance; at this time, it is better to avoid starting the active brake cylinder to avoid the vehicle braking; if the pressure detection element detects that the trampling force of a driver is large, when the emergency braking intention is reflected, the active braking oil cylinder can be started by the control system at the same time, and therefore the purpose of rapid braking and stopping is achieved.
Further preferably, the support is bent into a U shape from a plate, and reinforcing ribs are formed at root parts of two sides of the U shape; the sleeve is confined within the U-shaped slot of the holder. The rigidity and the strength of the support are improved, and the reliability of braking assistance and active braking is ensured.
Further preferably, the two sides of the support are formed with reinforcing flanges, and the flanges on the two sides extend along the back of the U-shaped groove. Further enhancing the rigidity and strength of the support.
Further preferably, the first arm and the second arm are circumferentially offset by 90 degrees. To form a compact layout structure, facilitating saving of vehicle space.
The beneficial effects of the utility model are that, the original braking helping hand system of make full use of to simplify the structure, make things convenient for the overall arrangement, and have braking helping hand, initiative braking and quick braking effect.
