Abstract
The utility model discloses a kind ofly for the improvement type cylinder on clutch booster, comprise the cylinder block of tubular, form mounting hole at the end face middle part of cylinder block, outer ledge place form 2 identical with mounting hole towards vent slot; Bottom surface in cylinder block forms evagination outlet end, forms the tapped locating column of convex on bottom surface; On the outer side wall of cylinder block, form two gas guide grooves; The utility model installation concentricity high efficiency is high, has good positioning and is not shifted simultaneously between piston and spring, improves usability.
Description
Technical field
The utility model is mainly concerned with the clutch operation of vehicle transmission, especially relates to a kind of for the improvement type cylinder on clutch booster.
Background technique
At present, in the clutch operating system of heavy-duty car, motor bus and engineering machinery, because controlled clutch pedal is firmly heavy, can not cut off easily power in good time, easily gearshift, generally between clutch and clutch master cylinder, clutch booster is installed, is used the compressed gas source of vehicle to provide power-assisted for clutch.
And clutch booster on market is due to when mounted, Pneumatic cylinder structure Shortcomings, in use, installation is not easy can be offset not on same axis with oil hydraulic cylinder, cause the seal ring on seal ring and the piston on oil hydraulic cylinder, pneumatic cylinder piston also to wear and tear, occur the phenomenon of leakage of oil or gas leakage.In addition, when internal piston is installed,, built on the sand, cause piston long-term motion behind efficiency to decline when spring the location, have much room for improvement.
Model utility content
It is a kind of for the improvement type cylinder on clutch booster that the purpose of this utility model is to provide, and installation concentricity high efficiency is high, has good positioning and is not shifted simultaneously between piston and spring, improves usability.
For the improvement type cylinder on clutch booster, comprise the cylinder block of tubular, it is characterized in that: the end face middle part in cylinder block forms mounting hole, outer ledge place form 2 identical with mounting hole towards vent slot; Bottom surface in cylinder block forms evagination outlet end, forms the tapped locating column of convex on bottom surface; On the outer side wall of cylinder block, form two gas guide grooves.
The utility model is done further preferably, and described cylinder block is made with aluminum alloy material.
The utility model is done further preferably, and described cylinder block is one-step die casting.
The utility model is done further preferably, and described gas guide groove is welded on the outer wall of cylinder block.
The utility model is done further preferably, and described gas guide groove and cylinder block are formed in one.
The utility model is done further preferably to connecting hose between vent slot and gas guide groove.
Compared with prior art, the utility model has the advantage of:
1, the utility model forms evagination outlet end in the bottom surface of cylinder block, when evagination outlet end is installed with oil hydraulic cylinder like this, be easy to aim on same axis, there will not be deviation, life-span and performance improve greatly, be not easy to occur the phenomenon of leakage of oil or gas leakage, greatly increase the service life and improve usability, and adopting aluminum alloy material to make, being not easy corrosion.And when mounted, carry out snaps into position and add bolt fixing by locating column, be not easy skew displacement, so compared with prior art, install very conveniently, efficiency is high.
2, in the utility model, locating column is convex, and the spring on piston is carried out to buckle, prevents that spring from ejecting, and spring there will not be skew, even under long piston movement, also there will not be skew, improves the utilization efficiency of booster.
3, the utility model forms mounting hole at the end face middle part of cylinder block; outer ledge place form 2 identical with mounting hole towards vent slot; vent slot be arranged on that gas guide groove on the outer side wall of cylinder block is identical carries out exhaust; change vent has been set on existing booster on dust cap; so this structure can effectively reduce the Dust Capacity entering in cylinder; and be conducive to improve the inner dust of discharge, protect cylinder block and Sealing and inner element.
As from the foregoing, the utility model installation concentricity high efficiency is high, has good positioning and is not shifted simultaneously between piston and spring, improves usability.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model relates to a kind of for the improvement type cylinder on clutch booster, the cylinder block 1 that comprises tubular, is characterized in that: cylinder block 1 end face 2 middle parts form mounting holes 3, outer ledge place form 2 identical with mounting hole 3 towards vent slot 4; Bottom surface in cylinder block 1 forms evagination outlet end 5, forms the tapped locating column 6 of convex on bottom surface; On the outer side wall of cylinder block 1, form two gas guide grooves 7, described cylinder block 1 use aluminum alloy material is made, described cylinder block 1 is one-step die casting, described gas guide groove 7 is welded on the outer wall of cylinder block 1, described gas guide groove 7 is formed in one with cylinder block 1, connecting hose between vent slot 4 and gas guide groove 7.
More than that the technological scheme that the utility model embodiment is provided is described in detail, having applied principle and the mode of execution of specific case to the utility model embodiment herein sets forth, above embodiment's explanation, is only applicable to help to understand the utility model embodiment's principle; , for one of ordinary skill in the art, according to the utility model embodiment, in embodiment and application area, all can change to some extent, in sum, this description should not be construed as restriction of the present utility model meanwhile.
