The invention relates to parts of an automobile, and provides a mechanical push-pull type air brake control master valve. The mechanical push-pull type air brake control master valve comprises a sleeve type casing, wherein a spigot is arranged at one end of the casing. The mechanical push-pull type air brake control master valve is characterized in that a tapered sliding seat is mounted in the casing; a catch spring step and an arm drawing shaft are arranged at the small end of the tapered sliding seat; the arm drawing shaft extends out of the casing and is connected with a control stay rope; a return spring is mounted between the catch spring step and the spigot; two or more radial through holes are formed in a tapered section, corresponding to the tapered sliding seat, of the casing; an ejection rod is assembled in each through hole, and the inner end of the ejection rod is in pushing connection with the tapered surface of the tapered sliding seat; suction and exhaust valves corresponding to the ejection rods respectively are arranged on the outer wall of the casing, and lower ends of valve rods of the suction and exhaust valves are distributed by directly facing the ejection rods. The mechanical push-pull type air brake control master valve realizes multivariable control, is convenient to operate, reliable and accurate in work, good in synchronous property, compact in structure and convenient to mount and maintain and is mainly applied to air brake devices of passenger and goods motor vehicles.
Description
technical field [0001] The invention relates to auto parts, in particular to a mechanical push-pull air brake control master valve used in an air brake device of a motor vehicle. Background technique [0002] The existing air brake control main valve is mainly installed inside and outside the driver's cab. It adopts the push rod type working method, and the two inlet and outlet valve bodies are stacked up and down. When working, the brake pedal push rod pushes the upper inlet and outlet valves, and then Push down the inlet and outlet valves. The existing main valve has the following disadvantages: 1. The installation is limited, there are many pipelines, and it is not easy to install and maintain; 2. The brake push rod and the valve air pressure are in a relative working mode, there is resistance, and the operation is laborious; 3. Separate control The valves are opened sequentially, and the brake outlet pipeline is long, causing the brakes to be untimely and inaccurate; 4....
