Embodiment 1

[0021] An electric power-assisted braking system, the system includes a pedal 1, a push rod 7 whose tail end is connected to the middle of the pedal 1 through a rotating shaft 2, and a brake pad connected to the front end of the push rod 7. The system includes a push rod 7 along the An electric drive unit whose axis moves back and forth. Driven by the electric drive unit, the booster push rod 7 moves back and forth, realizing the advantages of light and sensitive braking at low speeds and high braking efficiency and quick response at high speeds.

[0022] Electric drive unit servo motor 4, worm gear and worm pair 3 meshing with the shaft of servo motor 4, worm gear and worm pair 3 is T-shaped, including the worm gear arranged horizontally on the top and the worm integrally arranged in the center of the bottom of the worm wheel, the worm gear and the shaft of servo motor 4 meshing, the bottom of the worm is provided with a gear 6 and meshes with the push rod 7.

Abstract

The invention relates to an electric power-assisted brake system. The system comprises a foot pedal, a push rod of which the tail end is connected to the middle of the foot pedal through a rotating shaft, and a brake pad which is connected to the front end of the push rod; the system comprises an electric driving unit which drives the push rod to move front and back along the axis of the push rod.Compared with the prior art, the electric power-assisted brake system combines the meshing of gears and power-assisted racks to realize power-assisted load transmission; the power-assisted racks arekey components of the power-assisted transmission, and a unique structure is designed; the design has the advantages of handiness and sensitivity of brake at a low speed and high braking efficiency and fast response at a high speed.

Description

technical field [0001] The invention relates to the technical field of automobile machinery, in particular to an electric power-assisted braking system. Background technique [0002] Brake boosters are brake boosting devices widely used in light-duty vehicles to medium-sized vehicles, and can be roughly divided into vacuum boosters, hydraulic boosters, and pneumatic boosters. [0003] The traditional vacuum booster brakes rely entirely on the engine running to inhale air to form a vacuum to achieve brake boosting. The typical feature is that if the engine is turned off, the vacuum boost will soon fail. At this time, the braking ability is greatly reduced. Therefore, after the car is turned off, the brakes can only be stepped on three times normally, and then the power will be lost after stepping on it. The brake pedal cannot be stepped down, and the natural braking effect is difficult to guarantee. At the same time, the hydraulic power booster also has defects such as oil...
