Dual-oil-feed mechanism of brake master cylinder

Abstract

The invention discloses a dual-oil-feed mechanism of a brake master cylinder. The mechanism comprises a cylinder body, wherein the cylinder body is internally provided with an oil chamber; the outer wall of the cylinder body is provided with a concave cavity and is equipped with a valve cover; a cavity is formed between the valve cover and the peripheral wall of the concave cavity; the inner side of the valve cover is provided with an axial blind hole; the cavity is internally provided with a valve core; the upper end of the valve core is installed in the blind hole in a sliding fit mode; two sides of the middle part and the bottom part of the valve core are respectively provided with an upper valve seat and a lower valve seat; the outer walls of the middle part and the bottom part of the valve core are respectively provided with an upper valve clack and a lower valve clack which respectively press the upper valve seat and the lower valve seat; the valve clack and the upper valve seat separate the cavity into an upper chamber and a lower chamber; the upper chamber is communicated with the oil chamber; a spring is connected between the upper valve clack and the lower valve clack; and the parts of the cylinder body, under the upper valve clack and the lower valve clack, are respectively provided with an upper oil-feed port and a lower oil-feed port which are communicated with the lower chamber. The mechanism provided by the invention is reasonable in structure, can feed oil into the oil chamber synchronously, and the oil-feed speed is improved effectively, thus the working efficiency of the brake master cylinder is improved, and the oil return phenomenon can not happen.

Description

technical field [0001] The invention relates to the field of automobile brakes, in particular to a double oil inlet mechanism of a brake master cylinder. Background technique [0002] The brake master cylinder generally relies on compressed air or oil to enter the brake cylinder, and pushes a set of basic devices such as the piston to perform the braking function. It is a part of the automobile brake and is used to generate the force that hinders the movement or movement trend of the vehicle, that is, the braking force. . [0003] Most of the existing brake master cylinders are provided with only one oil inlet, and the oil inlet speed is relatively slow, thereby greatly affecting the working efficiency of the brake master cylinder. Contents of the invention [0004] The purpose of the present invention is to provide a double oil inlet mechanism of the brake master cylinder, which improves the oil inlet speed, thereby improving the working efficiency of the brake master c...
