Technical Field
The utility model relates to a brake master cylinder assembly in the technical field of automobile brake systems, in particular to a brake master cylinder with an improved structure of a second oil outlet of a master cylinder.
Background
The main function of the brake master cylinder assembly is to convert the force applied by a driver on a brake pedal into hydraulic pressure, and the brake fluid with certain pressure is sent to the brake wheel cylinders of all wheels through the brake pipelines connected with the oil outlets of the main cylinder body, and the brake wheel cylinders convert the hydraulic energy into mechanical energy so as to realize the braking of the vehicle.
The main cylinder body is one of main parts of the brake main cylinder assembly, the internal structure of the main cylinder body is mainly divided into a first cylinder body cavity and a second cylinder body cavity, the first cylinder body cavity is connected with a first oil inlet and a first oil outlet, the second cylinder body cavity is connected with a second oil inlet and a second oil outlet, the first oil outlet and the second oil outlet are respectively connected with a brake pipeline, and the main functions of the brake main cylinder are that when a vehicle brakes, brake fluid is guaranteed to flow from the oil outlets to the brake pipeline, and the hydraulic pressure is transmitted to brake cylinders of four wheels, so that hydraulic braking is finally realized.
According to the requirements of the loading space and the position of a brake pipeline, the direction of a second oil outlet of a main cylinder body needs to be downward, the diameter of a second cavity of the main cylinder body (shown in figure 4) is phi 25+/-0.2 mm, the outer diameter of the second cavity of the main cylinder body is phi 39+/-0.3 mm, the structure (shown in figure 2) of the main cylinder body is that the second cavity 1 of the main cylinder body is communicated with a horizontal second oil outlet channel 4, the second oil outlet channel 4 is sealed by steel balls 3, and the horizontal second oil outlet channel 4 is communicated with a vertical second oil outlet channel 2.
Disclosure of Invention
The utility model provides a braking main cylinder body with an improved second oil outlet structure of the main cylinder body, which aims to solve the problems that the sealing performance of a braking main cylinder assembly is invalid due to the rupture of a steel ball hole, braking liquid leaks, a vehicle cannot be braked, and the cylinder body structure is complex.
The technical scheme adopted is as follows: the second cavity of the main cylinder body is directly communicated with the second oil outlet channel in the vertical direction, and the inner diameter and the outer diameter of the second cavity of the main cylinder body are increased.
The inner diameter of the two cavities of the main cylinder body is increased to phi 35 plus or minus 0.2mm, and the outer diameter is increased to phi 47 plus or minus 0.3mm.
The distance between the axis of the two cavities of the main cylinder body and the axis of the second oil outlet channel in the vertical direction is 16+/-0.1 mm.
The utility model has the advantages of novel structure, improved structure of the second oil outlet channel of the original main cylinder body, elimination of the second oil outlet channel in the horizontal direction and steel balls at the position where the second oil outlet channel of the main cylinder body is communicated with the two cavities of the main cylinder body, good sealing performance, avoiding the risk of leakage caused by unstable sealing performance of the steel balls, ensuring the safety performance of the vehicle, reducing the processing amount, shortening the processing time, reducing the cost, improving the production efficiency and improving the reliability and the safety of the product.
