Abstract
The utility model provides an automobile brake system is with rousing piston of stopping, includes piston only (1), piston only (1) on offer mounting groove (2) that are used for suit sealing rubber circle, the width of mounting groove (2) widen gradually from the notch to the tank bottom, the diapire of mounting groove (2) on be provided with adhesive layer (3) that are used for sticking the sealing rubber circle, the lateral wall of notch department of mounting groove (2) on be provided with the opening and expand pawl (4) in order to bite into the sealing rubber circle towards tank bottom and prong to mounting groove (2) center directions. This automobile brake system is with rousing piston of stopping can firm suit sealing rubber circle.
Description
Technical field
The utility model relates to a kind of component for brake system of car, particularly relates to a kind of brake system of car and rouses piston of stopping.
Background technique
Drum is stopped as the one in brake system of car, and because having, cost is lower, the advantage of absolute brake Li Genggao, is more used on the trailing wheel of pony car.At present, comparatively common drum is stopped and is generally made up of relevant connecting rod, spring, pin, brake drums such as shoe sole, wheel cylinder, brake shoes.Piston wherein in wheel cylinder is one of critical component of drum braking.For making piston form good sealed environment in running, this piston is generally provided with the mounting groove for being set with sealing rubber ring.
And can mounting groove realize the firm installation of sealing rubber ring, making the sealing rubber ring after installation there will not be the project organization of the phenomenon that gets loose, is the capable focus that those skilled in the art pay close attention to always.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of brake system of car that firmly can be set with sealing rubber ring to rouse piston of stopping.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: comprise piston only, described piston only offers the mounting groove for being set with sealing rubber ring, the width of described mounting groove broadens gradually from notch to bottom land, the diapire of described mounting groove is provided with the adhesives layer for adhering and sealing rubber ring, the sidewall at the notch place of described mounting groove is provided with opening towards bottom land and crown to mounting groove central direction launch with the pawl biting sealing rubber ring.
Angle between the sidewall of described mounting groove and bottom land is 82 ° ~ 85 °, as preferably, angle between the sidewall of described mounting groove and bottom land is 84 °, these 84 ° is preferred value, can ensure that sealing rubber ring can be pressed in mounting groove easily, at utmost make again solid and reliable being sleeved in mounting groove of sealing rubber ring energy simultaneously.
Be provided with intermediate incline between described pawl and the sidewall of piston only, carry out connection pawl and piston only sidewall by intermediate incline, sealing rubber ring can easily be pressed in mounting groove.
After adopting above structure, the utility model tool has the following advantages: brake system of car of the present utility model drum piston of stopping broadens gradually because of the width of mounting groove from notch to bottom land, such mounting groove just defines taper mounting groove, and the width of mounting groove broadens gradually from notch to bottom land, wide and notch is narrow bottom the mounting groove of such formation, rubber ring to be sealed is pressed into after in mounting groove, sealing rubber ring just can tightly be stuck in mounting groove, add the pawl at adhesives layer on mounting groove diapire and notch place, make sealing rubber ring very firmly and reliably can realize suit.
Accompanying drawing explanation
Accompanying drawing is the sectional structure schematic diagram that brake system of car of the present utility model rouses piston of stopping.
As shown in the figure: 1 piston only, 2 mounting grooves, 3 adhesives layers, 4 pawls, 5 intermediate incline.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, brake system of car of the present utility model rouses piston of stopping, and comprising piston only 1, described piston only 1 offering the mounting groove 2 for being set with sealing rubber ring.
Unlike the prior art, the width of described mounting groove 2 broadens gradually from notch to bottom land, so just, define the taper mounting groove that bottom land is wide and notch is narrow, the mounting groove of the type structure can make the sealing rubber ring be pressed in groove be clamped by narrower notch.The diapire adding described mounting groove 2 is provided with the adhesives layer 3 for adhering and sealing rubber ring, and the sidewall at the notch place of described mounting groove 2 is provided with opening towards bottom land and crown to mounting groove 2 central direction launch with the pawl 4 biting sealing rubber ring, like this under the further effect of adhesives layer and pawl, sealing rubber ring is made very firmly to achieve suit.
As improvement, can be pressed in mounting groove for making sealing rubber ring, angle between the sidewall of described mounting groove 2 and bottom land can be 82 ° ~ 85 °, as preferably, in the present embodiment, angle between the sidewall of described mounting groove 2 and bottom land is set to 84 °, and this numerical value both can at utmost make sealing rubber ring realize firmly installing, and sealing rubber ring can be made again to be pressed in mounting groove.
As improvement, for making sealing rubber ring be pressed in mounting groove more easily, between described pawl 4 and the sidewall of piston only 1, be provided with intermediate incline 5.
Brake system of car of the present utility model rouses piston of stopping, by triple settings of taper cell body, pawl, adhesives layer, the realization that the sealing rubber ring be pressed in mounting groove can be very solid and reliable is installed, in the During Process of Long-term Operation of piston, the phenomenon that gets loose can not be there is easily, effectively improve the braking ability of brake system of car.
Claims (4)
