Description
Technical field
The utility model relates to a kind of vehicle manual brake activation valve, belongs to field of automobile.
Background technology
Car brake is meant the parts that produce the power that hinders vehicle movement or movement tendency; Wherein also comprise the retarding device in the auxiliary braking system; At present, the used drg of automobile nearly all is a friction-type, can be divided into two big types of drum-type and disc types; Rotating element in the drum type brake friction pair is a brake wheel, and its running surface is the face of cylinder; The rotating element of plate disc brake for the brake disc of rotation, is a running surface with the end face then.
Be used for letting tire and ground strengthen the equipment of friction coefficient, mainly be divided into drum-type and dish formula, also be used for Parking to use, fast braking of drum-type great efforts, but heating afterwards braking force descend soon; Dish formula braking technology property is big; Fast the not enough drum-type of braking force big, but still can keep fruit of comparatively good braking after the heating, and premium-quality dish formula is killed car 6 brake pumps is arranged; Can carry out fruit of good braking, so modern dolly all is to adopt disc brake.
Generally all be provided with foot brake and hand braking two on the automobile and overlap independently stop mechanism.The purpose of using braking is to force automobile to slow down until parking rapidly, or when descending, keeps certain speed of a motor vehicle, and in addition, it is not slippery also to can be used to make the automobile that rests to remain on the original place reliably.In driving, the correct use braked, and not only helps guaranteeing traffic safety, and helps saving fuel, reduces wear on tyres, prevents that parts from damaging.
The utility model content
For deficiency and the defective that solves prior art, the purpose of the utility model is to provide a kind of vehicle manual brake activation valve, and the utility model structure design is simple, and is easy to operate, and cost is low, and applicability is strong.
The utility model adopts following technical scheme to achieve these goals:
The vehicle manual brake activation valve comprises valve body, it is characterized in that: described valve body laterally has air extractor vent; The bottom of valve body also has vertical admission port, has valve pocket in the described valve body, and described valve pocket is provided with a valve core rod; Be provided with pull back spring between described valve core rod and the valve body, described vertical admission port top is placed with spring, and the top of spring is provided with valve plates; The bottom of valve core rod is pressed and is put on the valve plates; Described valve core rod top is rotated and is provided with cam, and described cam lower edge is fitted and is contacted with the top of valve core rod, is rotatably connected to dead man through the dead man set pin on the described cam.
Described vehicle manual brake activation valve is characterized in that: said vertical admission port place is provided with circular seal ring.
The advantage of the utility model:
The utility model structure relates to simply, and easy to operate, cost is low, and applicability is strong, can carry out automobile brake fast and effectively through dead man, and work efficiency is good.
Description of drawings
The structural representation of Fig. 1 the utility model.
