Abstract
The utility model discloses an easy-to-install brake master cylinder, comprising a cylinder body, wherein an inner cavity of the cylinder body is internally provided with two opposite pistons in a sliding manner; the front end surfaces of the pistons are provided with sinking grooves; and a spring is padded between the sinking grooves. The easy-to-install brake master cylinder is characterized in that the outer wall of the end part of the cylinder body is provided with a round clamping groove; dustproof covers are clamped on the round clamping groove; the edge positions of the dustproof covers are provided with V-shaped bending grooves; and the central positions of the dustproof covers are sheathed at the end parts of the pistons. The easy-to-install brake master cylinder adopts dual-layer sealing of leather bowls and auxiliary leather rings; and since the structure characteristics are adopted, the purpose of removing gas from the brake wheel cylinder by one-person operation is realized. Simultaneously, the easy-to-install brake master cylinder has the advantages that the structure is simple, and the cost of the original brake wheel cylinder is not increased basically.
Description
Technical field
The utility model relates to the automobile brake field, specifically belongs to the easy mounting brake master cylinder.
Background technique
The easy mounting brake master cylinder is made up of brake cylinder head, piston, piston rod, leather cup and release spring etc., through the effect of three-way valve, when making pressurized air get into master cylinder, promotes piston and plays braking action through a cover base apparatus.The structural design of present easy mounting brake master cylinder is reasonable inadequately, and volume is heavy, and braking effect is poor.
The model utility content
The purpose of the utility model provides a kind of easy mounting brake master cylinder; Reasonable in design; Adopt leather cup, secondary apron double-layer seal, owing to adopt the said structure characteristic, thereby realized that one man operation can get rid of the purpose of Brake drum gas in the jar; The utility model is simple in structure simultaneously, does not increase the cost of original wheel cylinder basically.
The technological scheme of the utility model is following:
The easy mounting brake master cylinder includes cylinder body, is slidingly fitted with two relative pistons in the inner chamber of cylinder body; The front-end face of piston has deep gouge; Be equipped with spring between the deep gouge, it is characterized in that: the end outer wall of cylinder body has circular draw-in groove, clamps dust-proof cover on the circular draw-in groove; Dust-proof cover edge has the curved groove of V-arrangement, and the dust cover centers place is set in the end of piston.
Have annular groove on the outer wall of described piston, be set with apron on the annular groove.
The inlet hole of the utility model feeds pressurized gas, and promotes the piston slip, thereby promotes the Driving force size of piston through the elastic force control of dust cover; Reasonable in design; Adopt leather cup, secondary apron double-layer seal, owing to adopt the said structure characteristic, thereby realized that one man operation can get rid of the purpose of Brake drum gas in the jar; The utility model is simple in structure simultaneously, does not increase the cost of original wheel cylinder basically.
