Abstract

The invention relates to a hydraulic braking force adjusting device for an electric-driven vehicle. The hydraulic braking force adjusting device comprises an oil storage chamber, a pressure adjusting device, a brake master cylinder, a left front wheel cylinder, a right rear wheel cylinder, a left rear wheel cylinder, a right front wheel cylinder, a vacuum booster and a brake pedal, wherein the oil storage chamber comprises a first oil port, a second oil port, a third oil port and a fourth oil port; the first oil port and the second oil port are connected with the pressure adjusting device, respectively; the third oil port and the fourth oil port are connected with a first brake fluid inlet and a second brake fluid inlet of the brake master cylinder, respectively; a first brake fluid outlet and a second brake fluid outlet of the brake master cylinder are connected with the pressure adjusting device, respectively; the pressure adjusting device is connected with the left front wheel cylinder, the right rear wheel cylinder, the left rear wheel cylinder and the right front wheel cylinder, respectively; and the brake master cylinder is also connected with the brake pedal through the vacuum booster. The hydraulic braking force adjusting device for the electric-driven vehicle, provided by the invention, has the advantages of simplicity in making, convenience in mounting and low cost.

Description

technical field [0001] The invention relates to a braking force regulating device, in particular to a hydraulic braking force regulating device for an electric drive vehicle. Background technique [0002] When the electric drive vehicle is braking, the drive motor can work in the generator mode to convert the mechanical energy in the braking process into electric energy, so that the energy economy of the whole vehicle is effectively improved, which is one of the differences from traditional internal combustion engine drive vehicles. . However, due to the intervention of the feedback braking force of the driving motor, it is necessary to adjust the hydraulic braking force in real time during the braking process, so that the sum of the hydraulic braking force and the feedback braking force of the driving motor meets the driver's braking demand, which will affect the braking force. In order to improve the comfort of the brake pedal and ensure the safety of the braking process,...
