Abstract
The utility model relates to a hydraulic brake, in particular to a wheel cylinder double-lip packing cup of the hydraulic brake. The wheel cylinder double-lip packing cup comprises a cylinder body, a piston assembly is disposed in the cylinder body, and the upper portion and the lower portion of the piston assembly are respectively sealed through the double-lip packing cup. The wheel cylinder double-lip packing cup is simple in structure and strong in sealing, prolongs service life and improves product quality.
Description
Technical field
The utility model is a kind of hydraulic brake, particularly a kind of wheel cylinder lips mouth leather cup of hydraulic brake.
Background technique
Car hydraulic brake wheel cylinder of the prior art is to adopt single lip leather cup structure, because this structure cup packing property is poor, the life-span is short, so this structure wheel cylinder will often keep in repair and change.
Chinese patent CN200920151485.9; A kind of leather cup seal structure is disclosed; The utility model is made up of mount inlet, the running shaft of equipment and the leather cup of obturaging, and leather cup is installed on the mount inlet of equipment, and running shaft is installed on the leather cup; The mount inlet of equipment is provided with a circle cone tank in the position that leather cup is installed, described cone tank is near the angle of the bus of leather cup installation direction and the installation direction angle greater than opposite side bus and installation direction.This cup packing property is relatively poor, and working life is relatively poor relatively, and using effect is general simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, and is simple in structure, and Safety performance is high, the wheel cylinder lips mouth leather cup of the hydraulic brake of long service life.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of wheel cylinder lips mouth leather cup of hydraulic brake comprises cylinder body, is provided with piston assembly in the described cylinder body, and the upper and lower of described piston assembly seals through the lip leather cup respectively mutually.
The lip leather cup has better sealing, improves the working life of product.
As preferably, the outer ring of described lip leather cup is provided with outward extending outer lip, and the contacting point of described lip leather cup and cylinder body is provided with groove.
Outer lip has the introduced contaminants of preventing and gets into, and influences lip seal, is provided with groove; Can store a certain amount of grease at groove; Long-term lubrication is played in cylinder hole and lip leather cup, prevent that cylinder hole sealing position from getting rusty, guarantee sealability, prolong lip leather cup working life.
As preferably, described groove is circular-arc.
Therefore, the wheel cylinder lips mouth leather cup of the hydraulic brake that the utility model provides, simple in structure, sealing is strong, improves working life, promotes product quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
