Abstract

The invention discloses an electric power-assisted brake system with a large transmission ratio. The system comprises a motor, a first transmission pair, a second transmission pair, a third transmission pair and a power coupling mechanism, wherein the motor is connected with the first transmission pair and drives the first transmission pair to work, after the second transmission pair and the thirdtransmission pair are sequentially connected to the first transmission pair, the first transmission pair, the second transmission pair and the third transmission pair are driven by the motor to achieve linkage, and the power coupling mechanism is connected with the third transmission pair. The system has the advantages that the problems that due to the fact that the transmission ratio of an existing electric power-assisted brake system is low, maximum brake force is not large enough, and the current of the motor is excessively large are solved, and an effective solution is provided for intelligentization of a heavy vehicle brake system.

Description

technical field [0001] The invention relates to an electric power-assisted braking system, in particular to an electric power-assisted braking system with a large transmission ratio. Background technique [0002] At present, with the rapid development of electric vehicles and smart vehicles, the electric power-assisted braking system will gradually replace the vacuum-assisted system commonly used in traditional vehicles because it does not require a vacuum source and can realize braking energy recovery. The current electric power-assisted braking system mostly adopts one-stage or two-stage deceleration schemes, and the transmission ratio is generally small, which requires high motor power. Therefore, the motor drive unit is often damaged due to overheating due to excessive current during actual testing or use. Case. It is only suitable for small cars that do not require high maximum braking force, and is not practical for commercial vehicles and other heavy vehicles. Cont...
