Abstract
The utility model discloses a hydraulic slave pump, including having the cast aluminium cylinder body of inner chamber, the open end fixed mounting of cast aluminium cylinder body has the dust cover, and slidable mounting has the piston in the cast aluminium cylinder body, and the one end of piston is equipped with the push rod, and the free end of push rod stretches out the dust cover, in the cast aluminium cylinder body intracavity be equipped with with piston fixed connection's return spring, be equipped with the leather cup on the lateral wall of piston, it has a plurality of guidance raised to distribute on the outer peripheral face of leather cup, be equipped with on the internal surface of cast aluminium cylinder body with guidance raised complex spout, because the interior intracavity of cast aluminium cylinder body is equipped with the return spring with piston fixed connection, can carry out automatic replenishment to reducing impact and noise, because the cylinder body is made for the cast aluminium material, reduced the whole weight of hydraulic slave pump like this, reduced the pollution, guidance raised cooperates with the spout, has both strengthened the sealing performance of leather cup, has reduced the wearing and tearing and the dead phenomenon of piston card of leather cup again, has improved properties of product to the life of wheel cylinder has been prolonged.
Description
Technical field
The utility model relates to Clutch Technology field, particularly relates to a kind of hydraulic shunt pump.
Background technique
At present, clutch is arranged between motor and speed changer, is the total member be directly associated with motor in automotive transmission.Usual clutch and engine crankshaft flywheel group are installed together.And in car control mechanism clutch uses is all conventional hydraulic shunt pump, decide the reaction velocity of clutch.In the linkage structure of existing piston and push rod, behind the gap that clutch plate wearing and tearing are produced, can not automatically supplement, and easily produce noise and impact, the cylinder body manufactured by it gets rusty easily at the corrosion lower inner cavity of its environment, cause wearing and tearing and the seizure of piston phenomenon of leather cup, test its operating life lower than 200,000 times, thus affect the working life of wheel cylinder.
Model utility content
Technical problem to be solved in the utility model is to provide one can reduce overall weight, decreasing pollution, can enhance product performance, and the hydraulic shunt pump increased the service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: hydraulic shunt pump, comprise the cast aluminium cylinder block with inner chamber, the opening end of described cast aluminium cylinder block is installed with dust-proof cover, piston is slidably fitted with in described cast aluminium cylinder block, one end of described piston is provided with push rod, the free end of described push rod stretches out described dust-proof cover, the return spring be fixedly connected with described piston is provided with in described cast aluminium cylinder block inner chamber, the sidewall of described piston is provided with leather cup, the outer circumferential face of described leather cup is distributed with some guide protrusions, the internal surface of described cast aluminium cylinder block is provided with the chute coordinated with described guide protrusions.
As the improvement to technique scheme, described guide protrusions is evenly distributed on the outer circumferential face of described leather cup.
As the improvement to technique scheme, the outer surface of described cast aluminium cylinder block is provided with hard anodize layer.
Owing to have employed technique scheme, hydraulic shunt pump, comprise the cast aluminium cylinder block with inner chamber, the opening end of described cast aluminium cylinder block is installed with dust-proof cover, piston is slidably fitted with in described cast aluminium cylinder block, one end of described piston is provided with push rod, the free end of described push rod stretches out described dust-proof cover, the return spring be fixedly connected with described piston is provided with in described cast aluminium cylinder block inner chamber, the sidewall of described piston is provided with leather cup, the outer circumferential face of described leather cup is distributed with some guide protrusions, the internal surface of described cast aluminium cylinder block is provided with the chute coordinated with described guide protrusions, owing to being provided with the return spring be fixedly connected with piston in cast aluminium cylinder block inner chamber, automatically can supplement, thus reduce impact and noise, because cylinder body is that casting aluminium material is made, which decrease hydraulic shunt pump overall weight, decrease pollution, guide protrusions coordinates with chute, both the sealability of leather cup had been enhanced, again reduce wearing and tearing and the seizure of piston phenomenon of leather cup, improve product performance, and extend the working life of wheel cylinder.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1-cast aluminium cylinder block; 2-dust-proof cover; 4-piston; 5-push rod; 6-return spring; 7-leather cup; 81-guide protrusions; 82-chute.
Embodiment
In order to there be understanding clearly to technical characteristics of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.
As shown in Figure 1, hydraulic shunt pump, comprise the cast aluminium cylinder block 1 with inner chamber, the opening end of described cast aluminium cylinder block 1 is installed with dust-proof cover 2, piston 4 is slidably fitted with in described cast aluminium cylinder block 1, one end of described piston 4 is provided with push rod 5, the free end of described push rod 5 stretches out described dust-proof cover 2, the return spring 6 be fixedly connected with described piston 4 is provided with in described cast aluminium cylinder block 1 inner chamber, the sidewall of described piston 4 is provided with leather cup 7, the outer circumferential face of described leather cup 7 is distributed with some guide protrusions 81, and described guide protrusions 81 is evenly distributed on the outer circumferential face of described leather cup 7; The internal surface of described cast aluminium cylinder block 1 is provided with the chute 82 coordinated with described guide protrusions 81.
When oil-feed, the leather cup 7 on piston 4 can be made to open, effectively can prevent dust by dust-proof cover 2, in cast aluminium cylinder block 1 active chamber, produce pressure, promote piston 4 and push rod 5 outwards movement, then promote disengaging yoke by push rod 5, release bearing, separation platen.Clutch play can be reached from conditioning function by return spring 6, thus reduce impact and noise.
Described cast aluminium cylinder block 1 is made for casting aluminium material, which decreases hydraulic shunt pump overall weight, decreasing pollution; Guide protrusions 81 coordinates with chute 82, has both enhanced the sealability of leather cup 7, again reduces wearing and tearing and piston 4 stuck phenomenon of leather cup 7, improves product performance, and extend the working life of wheel cylinder.
The outer surface of described cast aluminium cylinder block 1 is provided with hard anodize layer.Cast aluminium cylinder block 1, after hard anodize, has that quality is good, rub resistance, corrosion resistant advantage, can extend the working life of cast aluminium cylinder block 1 like this.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
