Abstract
The utility model relates to a reversing double-H valve of a transmission case, which comprises an upper cover, a valve body, an end cover, a piston and a valve rod, wherein the piston is in clearance fit with the inner cavity of the upper cover, and a guide device is arranged between the piston and the inner cavity of the upper cover; and the piston is provided with a groove, the guide device is a guide ring, the guide ring is sleeved inside the groove of the piston, and the guide ring is matched with the inner cavity of the upper cover. Since the guide device is arranged between an air cylinder and the piston, the reversing performance is guaranteed to stay at a stable status, and the stability and the service life are improved.
Description
Technical field
The utility model relates to a kind of automobile accessory, especially relates to a kind of gearbox commutation double H valve.
Background technique
The employed double H valve of changement of conventional commercial car gearbox is because piston is to move reciprocatingly to realize the switching of gearbox at high and low retaining.Every work once, piston will follow by action once, piston and loam cake are Spielpassung, and piston is to move reciprocatingly, so piston and loam cake can produce local rigidity friction, piston and valve body all can have wearing and tearing to a certain degree behind the certain number of times of work like this, the roughness of endoporus that cooperates and axle also can be worse and worse, finally cause piston motion meeting hair fastener even stuck phenomenon, thereby cause high gear delivery outlet and low gear delivery outlet that output can not be arranged smoothly in turn, gearbox also just can not carry out normal high to low gear commutation.Because piston does not consider that it the time increases its guidance quality in motion and increases its life-span, and is higher because of frequency when regular meeting causes product in work, and causes commutation untimely, can hair fastener during piston motion, even the piston bad phenomenon such as can not commutate that is stuck.This traditional double H valve does not have the reliable guarantee of work, and working life is not long yet.
The model utility content
The utility model purpose is to overcome above-mentioned deficiency, is provided with guiding device on piston, keeps piston during to-and-fro motion, to avoid the rigidity friction between piston and the loam cake, to increase its reliability and working life in loam cake.
The technological scheme that technical problem adopted that the utility model solves is: a kind of gearbox commutation double H valve, comprise loam cake, valve body, end cap, piston, valve rod, piston and last cover cavity Spielpassung is characterized in that being provided with guiding device between piston and last cover cavity.
In concrete the enforcement, above-mentioned piston is provided with groove, and guiding device is a guide ring, and guide ring is set in the groove of piston, and guide ring and last cover cavity are suitable.
Be provided with a guiding device on piston, its advantage has been good guidance quality, has strengthened the stationary performance of piston motion, under frequent operation favourable raising the life-span of double H valve.Guiding device is a guide ring, and guiding device is to have designed a guide ring on piston, and guide ring is selected the good material of wear-resisting property for use.The utility model is loaded onto a guide ring on piston, piston is when carrying out axially reciprocating like this, the gap of piston and valve body can be directed to ring and support, avoided the rigidity friction between piston and the loam cake effectively, add that guide ring selects the good material of wear-resisting property for use, very wear-resisting, make commutation ability of the present utility model remain on very stable status like this, also improved the working life of used double H valve greatly.
The beneficial effects of the utility model are: the utility model guarantees that commutation ability remains on very stable status, has improved stability and working life owing to be provided with guiding device at cylinder and piston space.
Description of drawings
Below in conjunction with drawings and Examples model utility is further specified.
Fig. 1 is the utility model embodiment's a structural representation.
Among the figure: 1, loam cake 2, valve body 3, end cap 4, piston 5, valve rod 6, guide ring
Embodiment
Among Fig. 1, a kind of gearbox commutation double H valve, comprise loam cake 1, valve body 2, end cap 3, piston 4, valve rod 5, piston 4 and loam cake 1 inner chamber Spielpassung, be provided with guiding device between piston 4 and loam cake 1 inner chamber, piston 4 is provided with groove, and guiding device is a guide ring 6, guide ring 6 is set in the groove of piston 4, and guide ring 6 and loam cake 1 inner chamber are suitable.
The same prior art of working principle among Fig. 1 is not described herein at this.The utility model embodiment is by the ventilation of control mouth and the switching of dying, realized that gearbox switches between high gear and low gear, and this moment piston 4 in loam cake 1 inner chamber to-and-fro motion, there has been the effect of guide ring 6 just can avoid rigidity friction between piston 4 and loam cake 1 inner chamber, improve the commutation ability of double H valve effectively, also improved the working life of product greatly.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, and any structure after simple transformation on the utility model basis all belongs to protection domain of the present utility model.
Claims (2)
