Abstract
The utility model discloses a double-piston type clutch master cylinder assembly with an oil cup provided with a dustproof device. The double-piston type clutch master cylinder assembly comprises a cylinder body, wherein the middle part of the cylinder body is provided with an oil chamber; the right end part of the oil chamber is provided with a hole baffle; the left end of the hole baffle is provided with a rear piston; the left end of a rear fixed seat is provided with a rear spring; the left end of the rear piston is provided with a stroke screw; the left end of the stroke screw is provided with a spring seat; the left side of the spring seat is provided with a front piston; the left end of a front fixed seat is provided with a front spring; the upper end of the middle part of the cylinder body is provided with a pair of oil inlet joints; the upper ends of the oil inlet joints are provided with the oil cups; the top parts of the oil cups are provided with oil cup covers; and the side edge of the cylinder body is provided with a plurality of pipe joints. The double-piston type clutch master cylinder assembly has the advantages that by adopting the structure that dustproof covers are arranged at the top parts of the oil cups and sealing rings are arranged under cover bodies, the dust and the humid air can be effectively prevented from entering the oil cups and further entering the cylinder body, the condition that the phenomenon of locking or oil leakage can not occur after the cylinder body is used for a long time is ensured, and the service life of a product is prolonged.
Description
Technical field
The utility model relates to the auto parts and components field, relates in particular to the double piston type clutch master cylinder assembly that a kind of lubricating cup has dust guard.
Background technique
Clutch master cylinder is used for the manipulation of automobile clutch, and the oil pressure that in master cylinder, is formed by outside pedal operation drives clutch operating through clutch working cylinder, thereby realizes the remote control of clutch and reduce pedal operation power; Clutch master cylinder structure in the past, its lubricating cup part is the structural design that the top directly has oiler mostly, and this kind structure does not have dust guard, and long-term use lets dust and moisture get into cylinder body easily, causes faults such as seizure of piston and leakage of oil.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content
The purpose of the utility model just provides the double piston type clutch master cylinder assembly that a kind of lubricating cup has dust guard; Solve clutch master cylinder structure in the past; Its lubricating cup part is the structural design that the top directly has oiler mostly; This kind structure does not have dust guard, and long-term use lets dust and moisture get into cylinder body easily, causes the problem of faults such as seizure of piston and leakage of oil.
The technological scheme that the utility model adopts is:
A kind of lubricating cup has the double piston type clutch master cylinder assembly of dust guard, comprises cylinder body: the cylinder body middle part has the grease chamber, and porose retaining is installed the right part by the grease chamber; Hole retaining left end is equipped with back piston, is set with the secondary apron in back on the back piston right-hand member outer wall, is set with the main apron in back on the back piston left end outer wall; The main apron left end in back is equipped with the back fixed base, and back fixed base left end is equipped with rear spring, and the back piston left end is equipped with the stroke screw; Stroke screw left end is equipped with spring seat; The spring seat left side is equipped with secondary piston, secondary apron before being set with on the secondary piston right-hand member outer wall, main apron before being set with on the secondary piston left end outer wall; Before main apron left end preceding fixed base is installed, preceding fixed base left end is equipped with front spring; Upper end, cylinder body middle part is provided with a pair of fuel inlet fitting, and the fuel inlet fitting upper end is equipped with lubricating cup, and the lubricating cup top is equipped with oil cup cap, and the oil cup cap upper end is equipped with fixing frame, and the oil cup cap lower end is equipped with seal ring; The cylinder body side has some pipe joints, and seal ring is installed in the pipe joint, and pipe joint is equipped with dust plug outward.
Said fuel inlet fitting is connected to the grease chamber through oil duct.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through installing dust cover at the lubricating cup top; And the structure that seal ring is installed under lid, can prevent effectively that dust and moisture from getting into lubricating cup, and then get into cylinder body; Guaranteed that long-term use of cylinder body also stuck or oil leakage phenomenon can not occur, improved the working life of product.
