Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0015] Such as figure 1 As shown, the pressurized hydraulic brake master cylinder of the present invention includes an oil pot 2 and two double-chamber hydraulic cylinders 1, 3 with the same structure and specifications arranged side by side. The oil pot 2 and two double-chamber hydraulic cylinders 1 and 3 are conjoinedly arranged. There are also two sub-push rods 4 that are respectively connected to the pistons of the two parallel conjoined double-chamber hydraulic cylinders in parallel. , to realize the synchronous work of two hydraulic cylinders. The four oil inlet holes of the two double-cavity hydraulic cylinders connected in parallel communicate with the oil pot respectively. The four oil outlet holes of the two double-cavity hydraulic cylinders connected in parallel are used to communicate with the brake cylinders.

Abstract

The invention discloses a boosting hydraulic brake master cylinder, which comprises an oil can and two double-cavity hydraulic cylinders which are conjoined abreast and identical in structure and specification, and further comprises two abreast sub-push rods in contacted connection with pistons of the two double-cavity hydraulic cylinders. The oil tank and the two double-cavity hydraulic cylinders are conjoined, and the two sub-push rods are fixed onto a bridging plate which is connected with a main push rod to realize synchronous operation of the two hydraulic cylinders. A brake system comprising the boosting hydraulic brake master cylinder comprises a brake sub-pump and an integrated oil pipe, and four oil outlets of the two conjoined-abreast double-cavity hydraulic cylinders of the boosting hydraulic brake master cylinder are communicated with the brake sub-pump through the integrated oil pipe. Brake pressure and brake reliability of the brake system can be effectively improved, brake effect is enhanced, and driving safety is improved.

Description

technical field [0001] The invention relates to a supercharged hydraulic brake master cylinder, and also relates to a braking system comprising the supercharged hydraulic brake master cylinder. Background technique [0002] The current motor vehicle hydraulic brake system consists of a dual-cavity hydraulic master cylinder and four sub-pumps. One way is connected to two front wheel brake cylinders, and one way is connected to two rear wheel brake cylinders. This kind of brake system has a simple structure, but since the master cylinder has only one hydraulic cylinder, the pressure is insufficient, and the braking effect is not ideal; if the hydraulic cylinder breaks down, it will cause the brake to fail. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressurized hydraulic brake master cylinder with enhanced pressure, which will not immediately cause brake failure if a hydraulic cylinder fails. Also provided ...
