Abstract
The invention discloses a piston structure of a slave cylinder of a clutch, which comprises a piston. A center boss is arranged on the top of the piston, a cap-shaped boss top is arranged at the top end of the center boss, the bottom of the piston is provided with an inner groove, an annular groove is arranged on the side wall of the piston, limit protruded rings are arranged on the groove wall of the sides and the bottom of the annular groove respectively, a lower sealing ring is arranged in the annular groove of the piston, annular fastening grooves are arranged on the inner wall and the bottom ring wall of the lower sealing ring, the limit protruded rings can be fastened into the annular fastening grooves, other limit protruded rings are arranged on the side wall of the center boss of the piston and the side wall of the top of the piston respectively, an upper sealing ring is sleeved outside the center boss, and other annular fastening grooves are arranged on the inner wall and the bottom ring wall of the upper sealing ring respectively. The piston structure of the slave cylinder of the clutch is simple in structure and easy to realize. Dislocation of the sealing rings can be prevented effectively so that sealing effect of the piston is improved.
Description
Technical field
The present invention relates to clutch field, be specially a kind of piston structure of clutch slave cylinder.
Background technique
Clutch is installed between motor and the speed changer, be in the automotive transmission directly and total member of interrelating of motor.Usually clutch is installed together with the engine crankshaft flywheel set, is the parts of cut-out and transferring power between motor and the automotive transmission.Clutch slave cylinder is a vitals of clutch, and the piston in the clutch slave cylinder need be provided with seal ring outward and seal.When clutch slave cylinder piston service time was long in the existing technology, the outer seal ring of piston was prone to misplace, and causes the reduction of piston seal effect.
Summary of the invention
The object of the invention provides a kind of piston structure of clutch slave cylinder, is prone to the problem of dislocation with the seal ring that solves piston in the existing technology clutch slave cylinder.
In order to achieve the above object, the technological scheme that the present invention adopted is:
The piston structure of clutch slave cylinder; Comprise piston body; It is characterized in that: said piston body top center is provided with central boss; The central boss top is provided with the platform top of cap shape; Piston body bottom has the side in piston body be that the conical surface, end face are the inside groove of curved surface, and the inside groove notch opens in the piston body bottom, also is provided with annular groove on the said piston body sidewall; Annular groove sidepiece cell wall, bottom cell wall are respectively arranged with position limiting convex ring; Be provided with lower seal in the piston body annular groove, corresponding separately annular groove position limiting convex ring position is respectively arranged with the annular slot that supplies each self-corresponding position limiting convex ring to snap on said lower seal inwall, the bottom turns wall, and said piston body central boss sidewall, piston body top sidewall also are respectively arranged with position limiting convex ring; Said central boss is with the last seal ring that is pressed in the piston body top outward, and position limiting convex ring position, corresponding piston body top is respectively arranged with the annular slot that supplies each self-corresponding position limiting convex ring to snap on the corresponding central boss sidewall of last seal ring inwall position limiting convex ring position, the bottom turns wall.
The present invention is simple in structure; Be easy to realize that the piston body central boss is outer, be respectively arranged with seal ring in the annular groove, on piston body central boss outer side wall, piston body top sidewall, annular groove sidepiece cell wall, annular groove bottom cell wall, position limiting convex ring is being set respectively simultaneously; At seal ring inner ring wall, bottom turns wall annular slot is set respectively; When seal ring is installed on the piston body like this, utilize position limiting convex ring to cooperate, carry out spacing seal ring with annular slot on the seal ring; Can prevent effectively that seal ring from misplacing, and improved the sealing effect of piston.
