Abstract
The utility model provides a kind of motorcycle brake wheel cylinder, including the interior pump housing provided with oil pocket, and the pump housing is provided with oil inlet, and the pump housing has a convex section built with piston, the head of piston, and the convex section extends the oil pocket of the pump housing, and the afterbody of piston is provided with shoe plate；Also include propulsion plant, rotation pushing body and adjusting screw rod that propulsion plant includes rocking arm, can moved axially along piston; rocking arm promotes body phase to fix with rotation; there is internal thread perforation in the middle part of rotation pushing body; adjusting screw rod is arranged in the internal thread perforation of rotation pushing body, and the end face and the convex section end contact of piston of adjusting screw rod.The utility model rotation pushing body drives gentle mobile forward again so that adjusting screw rod propelling piston works, so as to realize gentle parking braking.The depth that rotation pushing body rotates is installed to by adjusting adjusting screw rod simultaneously, reaches that adjustment piston is conditioned the process that screw rod can be promoted, the dynamics adjustment of brake is realized.
Description
Technical field
The utility model is related to motorcycle accessories, more particularly to motorcycle brake wheel cylinder.
Background technology
It, with the device for making vehicle deceleration, stopping or keep the functions such as halted state, is to make machine that rear brake of motorcycle, which is,
The machine components that movement parts in tool stop or slowed down.At present, motorcycle brake wheel cylinder generally promotes piston to realize using oil pressure
Service brake, promotes piston to realize parking braking, but can not realize gentle braking during parking by push rod.
Utility model content
The utility model solve technical problem be：A kind of motorcycle brake wheel cylinder is provided, can cross and realize gentle parking
Braking.
The technical solution of the utility model is：
A kind of motorcycle brake wheel cylinder, including the interior pump housing provided with oil pocket, the pump housing are provided with oil inlet, and the pump housing is built with work
Plug, the head of the piston has a convex section, and the convex section extends the oil pocket of the pump housing, and the afterbody of piston is provided with shoe plate；
Also include propulsion plant, rotation pushing body and adjusting screw rod that the propulsion plant includes rocking arm, can moved axially along piston, institute
State rocking arm promotes body phase to fix with the rotation, has internal thread perforation, the adjusting screw rod peace in the middle part of the rotation pushing body
In the internal thread perforation of the rotation pushing body, and the convex section end face of the end face of the adjusting screw rod and the piston connects
Touch.
The rotation promotes external according to there is dust cover.
The outer surface of the rotation pushing body is provided with screw thread, and rotation pushing body is rotatably arranged on described by screw thread
In the pump housing.
The rotation pushing body is provided with guide sleeve, and the provided circumferentially about of the guide sleeve has roller.
The beneficial effects of the utility model are：The utility model adjusting screw rod is arranged on the internal thread of the rotation pushing body
In perforation, and the convex section end contact of the end face of the adjusting screw rod and the piston, made during parking by the rotation of rocking arm
Obtain adjusting screw rod and drive rotation pushing body rotation, rotation pushing body drives gently mobile forward again so that adjusting screw rod, which is promoted, lives
Work is filled in, so as to realize gentle parking braking.The depth that rotation pushing body rotates is installed to by adjusting adjusting screw rod simultaneously,
Reach that adjustment piston is conditioned the process that screw rod can be promoted, realize the dynamics adjustment of brake.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
Referring to a kind of motorcycle brake wheel cylinders of Fig. 1, including the interior pump housing 1 provided with oil pocket, the pump housing 1 is provided with oil inlet, pump
Body 1 has a convex section 21 built with piston 2, the head of piston 2, and the convex section 21 extends the oil pocket of the pump housing 1, piston 2
Afterbody is provided with shoe plate 3；Also include propulsion plant, propulsion plant includes Rocker arm 4, can promoted along the rotation that piston 2 is moved axially
Body 5 and adjusting screw rod 6, Rocker arm 4 are mutually fixed with rotation pushing body 5, and the middle part of rotation pushing body 5 has internal thread perforation, adjusts spiral shell
Bar 6 is arranged in the internal thread perforation of rotation pushing body 5, and the end face of adjusting screw rod 6 connects with the end face of convex section 21 of piston 2
Touch.
Rotation pushing body 5 is outer according to there is dust cover 7.The outer surface of rotation pushing body 5 is provided with screw thread, rotates pushing body 5
Rotatably it is arranged on by screw thread in the pump housing 1.Rotation pushing body 5 be provided with guide sleeve 8, the guide sleeve 8 it is provided circumferentially about
There is roller 9.Adjusting screw rod 6 is arranged in the internal thread perforation of the rotation pushing body 5, and end face and the institute of the adjusting screw rod
The convex section end contact of piston is stated, causes adjusting screw rod to drive rotation pushing body to rotate by the rotation of rocking arm during parking, rotation
Turn pushing body and drive gentle movement forward again so that adjusting screw rod propelling piston works, so as to realize gentle parking braking.Together
When be installed to the depth that rotation pushing body rotates by adjusting adjusting screw rod, reach that what adjustment piston was conditioned that screw rod can promote enters
Journey, realizes the dynamics adjustment of brake.
