Abstract
The utility model discloses a clutch main pump assembly with an inclined oil inlet joint at the top. The clutch main pump assembly comprises a cylinder body, wherein the middle of the cylinder body is provided with an oil chamber, a piston is arranged at the right end in the oil chamber, a protection cover is arranged at the right end part of the cylinder body, a main leather ring and an oil return sheet are sheathed outside the left end of the piston, a fixing seat is arranged at the left end of the main leather ring, the left end of the fixing seat is provided with a spring, the upper end of the cylinder body is provided with an oil inlet joint, an oil inlet sealing ring is also arranged between the oil inlet joint and the cylinder body, a dustproof cap is arranged at the upper end of the oil inlet joint, the lower end of the cylinder body is provided with a pipe joint, a dustproof plug is arranged outside the pipe joint, and the oil inlet joint and the horizontal plane have a certain included angle in a range being 70 degrees to 80 degrees. The clutch main pump assembly has the advantages that the oil inlet joint is changed into the oil inlet joint in the inclined arrangement near the vertical state, in addition, the oil inlet sealing ring and the dustproof cap are arranged on the clutch main pump assembly, and dust and moisture in the air can be effectively prevented from entering the oil chamber, so an oil path cannot be easily blocked, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to the auto parts and components field, relates in particular to the clutch main cylinder assembly that a kind of top has the inclination fuel inlet fitting.
Background technique
Clutch master cylinder is the part that is connected clutch foot plate and is connected with clutch booster through oil pipe.Effect is to gather the effect of pedal travel information through booster to make clutch realize separating; Clutch master cylinder structure in the past, it goes into oily joint is parallel cylinder body design, makes dust and airborne moisture get into the grease chamber easily, and causes oil circuit to stop up easily.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content
The purpose of the utility model just provides the clutch main cylinder assembly that a kind of top has the inclination fuel inlet fitting; Solve clutch master cylinder structure in the past; It goes into oily joint is parallel cylinder body design, makes dust and airborne moisture get into the grease chamber easily, and causes the oil circuit blocking problem easily.
The technological scheme that the utility model adopts is:
A kind of top has the clutch main cylinder assembly of inclination fuel inlet fitting, comprises cylinder body: the cylinder body middle part has the grease chamber, and right-hand member is equipped with piston in the grease chamber; The piston right part is near the cylinder body right part, and the cylinder body right part is equipped with guard shield, ring washer is installed between piston and the guard shield and ends pad; The piston right-hand member is set with secondary apron outward, and the piston left end is set with main apron and oil return sheet outward, and main apron left end is equipped with fixed base; The fixed base left end is equipped with spring, and spring leans at the cylinder body left end; The cylinder body upper end is provided with into oily joint, goes into the oil-feed seal ring also is installed between oily joint and the cylinder body, goes into oily upper end of joint dust cap is installed; The cylinder body lower end is provided with pipe joint, and pipe joint is equipped with dust plug outward.
Saidly go between oily joint and the horizontal plane to have certain angle, angular range is 70 °-85 °.
Compared with prior art, the beneficial effect of the utility model is:
The utility model will be through changing subvertical being obliquely installed into will going into oily joint, and be installed into oil seal circle and dust cap, can prevent effectively that dust and airborne moisture from getting into the grease chamber, make oil circuit be difficult for stopping up the working life of having improved product.
