Abstract
The utility model discloses a floating seal ring leak-proof structure of a wet brake. The floating seal ring leak-proof structure of the wet brake comprises a hub, an inner gear ring, a piston, a connecting disc and a braking device. The floating seal ring leak-proof structure of the wet brake is characterized in that a movable sealing socket is arranged between the hub and the inner gear ring, oil sealing grooves are formed in the inner sides of the movable sealing socket and the inner gear ring, and adjusting shims are arranged between the movable sealing socket and the hub. Compared with the prior art, the floating seal ring leak-proof structure of the wet brake has the advantages that due to the arrangement of the movable sealing socket between the hub and the inner gear ring and the arrangement of the set of adjusting shims between the movable sealing socket and the hub, machining processes of other relevant parts are simplified, efficiency is improved, cost is reduced, rejection rates of relevant parts are reduced, and the sealing effect of a floating oil seal is guaranteed.
Description
Technical field
The utility model relates to wet brake, relates in particular to a kind of wet brake floating sealing ring sealing configuration, belongs to mechanical field.
Background technique
Break seals by floating sealing ring with the sealing on wheel limit in the ransaxle wet brake, this sealing has strict demand to pretightening force, too greatly then accelerated wear test of pretightening force, pretightening force is too little then seal unreliable, the meeting leakage of oil, the pretightening force detection is converted to a measurement size and is: 3 ± 0.5, original technology is that the machining accuracy by the dimensional chain correlated parts guarantees, this mode one improves correlated parts axial dimension precision, cost rises, in addition, as truly having overproof part also can not remedy adjustment, can only scrap.
The model utility content
The utility model provides a kind of wet brake floating sealing ring sealing configuration in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of wet brake floating sealing ring sealing configuration, comprise wheel hub, ring gear, piston, tie-plate and braking device, it is characterized in that: be provided with the motive sealing seat between described wheel hub and the ring gear, described motive sealing seat and ring gear inboard are provided with oil seal groove, are provided with the adjustment pad between described motive sealing seat and the wheel hub.
The utility model advantage compared with prior art is: be provided with the motive sealing seat between wheel hub and ring gear, between motive sealing seat and wheel hub, increase by one group again and adjust pad, simplified other correlated parts processing technology, promoted efficient, reduced cost, reduce the reject rate of correlated parts, also guaranteed the sealing effect of float grease seal simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of wet brake floating sealing ring sealing configuration, comprise wheel hub 1, ring gear 2, piston 3, tie-plate 4 and braking device 5, it is characterized in that: be provided with motive sealing seat 6 between described wheel hub 1 and the ring gear 2, described motive sealing seat 6 and ring gear 2 inboards are provided with oil seal groove 7, are provided with between described motive sealing seat 6 and the wheel hub 1 to adjust pad 8.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
