Abstract
The utility model discloses a device for quickly replacing pistons and dust covers in a brake wheel cylinder, and the device includes a cylinder body, wherein an air nozzle or an oil nozzle is arranged on the cylinder body, a radial through hole is arranged inside the cylinder body, a left piston and a right piston are arranged in the radial through hole respectively, the left and right pistons are matched with the hole wall of the radial through hole in a sliding manner, and a spring is connected between the left piston and the right piston; and further, annual grooves are arranged on the outer walls at both ends of the cylinder body, a plurality of screw holes arranged in a row are formed in the groove bottom of each annual groove, one of the screw holes in each groove bottom is screwed with a bolt, and the dust covers are clamped and mounted between the bolts and the inner walls of the annual grooves. The device has a simple structure, and can fix the dust covers through bolts screwed in the screw holes in the grooves; when the pistons and the dust covers in the cylinder are required to be replaced, the dust covers can be quickly demounted as long as the bolts are taken down, so that the purpose of quickly replacing the pistons and the dust covers is realized; and further, the device is convenient and quick to use, and saves time and labor.
Description
Technical field
The utility model relates to the automotive brake field, is specifically related to the device of a kind of quick replacing wheel cylinder inner carrier and dust-proof cover.
Background technique
Wheel cylinder generally relies on pressurized air or oil to get into master cylinder, and promotion piston etc. overlap base apparatus and play braking action, are parts of automotive brake, are used to produce the power that hinders vehicle movement or movement tendency, i.e. braking force.
Wheel cylinder is in long-term using process, and its inner piston can wear and tear, and need regularly change and safeguard, the frequent friction between dust-proof cover and the piston simultaneously also causes the dust-proof cover needs regularly to remove replacing.
The model utility content
The purpose of the utility model provides the device of a kind of quick replacing wheel cylinder inner carrier and dust-proof cover, realizes changing fast the purpose of piston and dust-proof cover.
The technological scheme of the utility model is following:
The device of a kind of quick replacing wheel cylinder inner carrier and dust-proof cover; Include cylinder body; Described cylinder body is provided with valve or oil nozzle, it is characterized in that: be provided with radial direction through hole in the said cylinder body, be provided with left and right piston in the described radial direction through hole; The hole wall of described left and right piston and radial direction through hole is slidingly matched, and is connected with spring between the left and right piston; Be respectively equipped with annular groove on the two ends outer wall of said cylinder body, the bottom land of annular groove is provided with a plurality of screws that are arranged in a row, and has screwed togather bolt in one of them screw, is installed with dust-proof cover between the inwall of described bolt and annular groove.
The device of described quick replacing wheel cylinder inner carrier and dust-proof cover is characterized in that: be respectively equipped with seal ring between the hole wall of described left and right piston and radial direction through hole.
The beneficial effect of the utility model:
The utility model is simple in structure, lives dust-proof cover through the bolt that is screwed on the groove inner bolt hole, when needs are changed cylinder interior piston and dust-proof cover; Only need take off bolt can pull down dust-proof cover fast; Thereby realize changing fast the purpose of piston and dust-proof cover, convenient and swift, time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; The device of a kind of quick replacing wheel cylinder inner carrier and dust-proof cover includes cylinder body 1, and cylinder body 1 is provided with valve or oil nozzle; Be provided with radial direction through hole 6 in the cylinder body 1; Be provided with left and right piston 7,4 in the radial direction through hole 6, the hole wall of left and right piston 7,4 and radial direction through hole 6 is slidingly matched, and left and right piston 7, is connected with spring 2 between 4; Be respectively equipped with annular groove 8 on the two ends outer wall of cylinder body 1, the bottom land of annular groove 8 is provided with a plurality of screws that are arranged in a row, and has screwed togather bolt 9 in one of them screw; Be installed with dust-proof cover 5 between the inwall of bolt 9 and annular groove 8, when needs were changed cylinder interior piston and dust-proof cover, only need take off bolt can pull down dust-proof cover 5 fast; Extract impaired piston and dust-proof cover then out; After changing, refill dust-proof cover, and tight a bolt and get final product; In the utility model, select in a row the screw certain screw on demand and twist and to close bolt, just the fixing big or small dust-proof cover of different size.
Further, be respectively equipped with seal ring 3 between the hole wall of left and right piston and radial direction through hole.
