Abstract
The utility model provides a hydraulic brake wheel cylinder for an automobile, belongs to the technical field of automobiles, and solves the technical problem that self clearance cannot be adjusted in the prior art. The hydraulic brake wheel cylinder comprises a cylinder body, wherein a hydraulic cylinder is arranged in the cylinder body; a piston is arranged in the hydraulic cylinder; a ring channel I is formed at the front end of the piston; a U-shaped seal ring is arranged in the ring channel I; a ring channel II is formed at the rear end of the piston; an O-shaped ring is arranged in the ring channel II; one end of the piston extends out of the hydraulic cylinder and is connected with a brake shift fork of the automobile; the brake shift fork is fixedly arranged on a ratchet wheel; the ratchet wheel is arranged in the cylinder body and at the front end of the piston; a screw pair I and a screw pair II, which are meshed with each other, are sleeved on the outer side surface of the piston; the screw pair I is connected with the piston; the screw pair II is fixedly connected with the ratchet wheel; and an adjusting nut is fixedly arranged at the outer end of the screw pair II. The hydraulic brake wheel cylinder has the advantages that the structure is simple, compact and reasonable; and self clearance can be adjusted.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of hydraulic vehicle braking wheel cylinder.
Background technique
The hydraulic vehicle braking wheel cylinder is a common components in the automobile, and usually the hydraulic braking wheel cylinder generally can not be adjusted its gap.
The model utility content
The purpose of the utility model is the problems referred to above that exist to existing technology, a kind of simple in structure, compact and reasonable is provided, can adjusts the hydraulic vehicle braking wheel cylinder in self gap.
The purpose of the utility model can realize through following technical proposal: a kind of hydraulic vehicle braking wheel cylinder, comprise the pump housing, and be provided with oil hydraulic cylinder in the pump housing; It is characterized in that be provided with piston in the described oil hydraulic cylinder, the front end of described piston offers circular groove one; Be provided with the U-shaped seal ring in the described circular groove one; The rear end of described piston offers circular groove two, is provided with O type circle in the described circular groove two, and an end of described piston extends to outside the oil hydraulic cylinder and with the braking shiifter of automobile and is connected; Described braking shiifter is installed on the ratchet; Described ratchet is arranged in the pump housing and is positioned at the front end of piston, and the outer side surface of described piston is arranged with the screw pair one and screw pair two that is meshed, and described screw pair one is connected with piston; Described screw pair two is connected with ratchet mutually, and the outer end of described screw pair two is installed with an adjustment nut.
The working principle of this device is following: drive braking shiifter through seesawing of piston and move; Again because braking shiifter is connected with ratchet; Braking shiifter can be unaffected when piston reverses direction moves; Make when there is the gap in brake cylinder, can adjust the gap of screw pair one and screw pair two through the adjustment nut.
Compared with prior art, simple in structure, the compact and reasonable of this hydraulic vehicle braking wheel cylinder, can adjust self gap.
Description of drawings
