Embodiment

[0032] see figure 1 As shown, the embodiment of the present invention provides a hydraulic braking system, including a pedal mechanism, a servo mechanism and a braking force distribution system; the pedal mechanism includes an input rod 102 and a brake pedal 101, the servo mechanism includes a core tube 103, and the braking force distribution system The system includes a brake master cylinder; the brake pedal 101 is hinged to one end of the input rod 102, and the other end of the input rod 102 is used to push the master cylinder piston 105 of the brake master cylinder to move; the core tube 103 is sleeved on the input rod 102, Used to assist the input rod 102 to move the master cylinder piston 105 of the brake master cylinder.

[0033] Specifically, when the driver steps on the brake pedal 101, the brake pedal 101 can make the input rod 102 move along the axial direction of the input rod 102 itself, so as to push the master cylinder piston 105 to move; The movement of the mas...

Abstract

The invention relates to the technical field of automobile braking, in particular to a hydraulic braking system. The hydraulic braking system comprises a pedal mechanism, a servo mechanism and a braking force distribution system. The pedal mechanism comprises an input rod and a brake pedal. The servo mechanism comprises a core pipe. The braking force distribution system comprises a brake master cylinder. The brake pedal is hinged to one end of the input rod. The other end of the input rod is used for pushing a master cylinder piston of the brake master cylinder to move. The input rod is sleeved with the core pipe used for assisting the input rod in pushing the master cylinder piston of the brake master cylinder to move. Through the hydraulic braking system, precise control over assistance can be achieved, the pedal feeling of a driver is ensured, and the driver can select an appropriate pedal mode according to different driving conditions. In addition, the hydraulic braking system abandons a traditional vacuum assistance mode, and thus during braking, the core pipe can also push the master cylinder piston of the brake master cylinder to move while the brake pedal pushes the master cylinder piston of the brake master cylinder to move.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a hydraulic braking system. Background technique [0002] At present, the brake booster used on most automobiles is still a vacuum booster, which is the core component of the vacuum booster servo braking system, which mainly uses the pressure difference between the vacuum and the atmosphere to generate boost. It is provided by the engine of the conventional vehicle. The vacuum booster is generally located between the brake pedal and the brake master cylinder. For ease of installation, it is usually combined with the master cylinder as a component, and a part of the brake master cylinder goes deep into the vacuum booster housing. The thrust generated by the vacuum booster acts on the piston of the master cylinder of the brake master cylinder, and the electronic control unit (ECU) controls the on-off of each solenoid valve in the brake circuit to control the flow direct...
