Description

Wheel limit wet brake
Technical field
The utility model belongs to the break technical field in engineering machinery, particularly one wheel limit wet brake.
Background technique
As shown in Figure 1, existing one wheel limit wet brake, comprises hub 1, back shaft 2, semiaxis 3, ring gear 4, gear ring support 5, friction plate group 6 and fixed support 7, back shaft 2, semiaxis 3, ring gear 4, gear ring support 5, friction plate group 6 and fixed support 7 are arranged in hub inner chamber, friction plate group 6 needs lubricant oil to lubricate it, take turns back shaft 2 in the wet brake of limit offer the first oil inlet hole 21 at this, the oil inlet passage 8 be communicated with the first oil inlet hole 21 is formed between back shaft 2 with fixed support 7, fixed support 7 is offered the second oil inlet hole 71, the oil inlet end of friction plate group 6 is communicated with oil inlet passage 8 by the second oil inlet hole 71, the first drainback passage 9 is formed between ring gear 4 and gear ring support 5, the second drainback passage 10 is formed between semiaxis and back shaft, friction plate group 6 oil outlet end is communicated with hub inner chamber 11 by the first drainback passage 9, second oil discharge passage 10 by hub inner chamber 11 and Driving axle housing inner space, the first oil inlet hole 21, oil inlet passage 8, second oil inlet hole 71, first drainback passage 9, hub inner chamber 11 and the second drainback passage 10 are communicated with the lubrication oil circulation loop forming wheel limit wet brake successively, and lubricating oil flow distance is: lubricant oil enters wheel limit wet brake, through oil inlet passage 8 from the first oil inlet hole 21, second oil-feed 71 hole engaging friction sheet group 6 is lubricated, from friction plate group 6 lubricant oil out through the first drainback passage 9, hub inner chamber 11 and the second drainback passage 10 are back in the inner chamber of Driving axle housing.
Also there is following defect in above-mentioned limit wet brake of taking turns: because the gap (i.e. the first oil return oil passage 9) between gear ring support 5 and ring gear 4 is less, oil circuit is easily blocked, again because the gap (i.e. the second oil return oil path 10) between semiaxis 3 and back shaft 2 is also smaller, cause lubricant oil in hub inner chamber can not quick backflow in the inner chamber of Driving axle housing, cause friction plate group 6 to lubricate smooth, high oil temperature, easily make the Sealing in rim brake impaired, even cause the series of problems such as lubricant oil mixes with brake fluid, deterioration of lubricant.
In view of this, the present inventor improves wheel limit wet brake, and especial manufacture goes out a kind of wheel limit wet brake with excellent oil circuit structure, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of wheel limit wet brake, which solves the circulation of lubrication oil circulation loop and does not freely even block the series of problems caused, improve the continuous firing ability of break, reduce the generation of fault.
To achieve these goals, the technical solution of the utility model is as follows:
Wheel limit wet brake, comprise hub, back shaft, semiaxis, ring gear, gear ring support, friction plate group and fixed support, back shaft, semiaxis, ring gear, gear ring support, friction plate group and fixed support are installed in hub inner chamber, back shaft offers the first oil inlet hole, first oil inlet hole is communicated with the inner chamber of Driving axle housing, form oil inlet passage between back shaft and fixed support, fixed support offers the second oil inlet hole; Described ring gear and hub all offer multiple spill port, back shaft is at least offered a spill port, hub inner chamber forms circular groove, back shaft spill port is also communicated with the inner chamber of Driving axle housing, described first oil inlet hole, oil inlet passage, the second oil inlet hole, ring gear spill port, circular groove, hub spill port be communicated with successively with back shaft spill port and in conjunction with Driving axle housing inner chamber form lubrication oil circulation loop.
Further, described ring gear spill port to offer direction consistent with friction plate group.
Further, described hub spill port, between the bearing and outside framework oil seal of back shaft, forms oil discharge passage between bearing and outside framework oil seal, and hub spill port is communicated with back shaft spill port by oil discharge passage.
Further, the width of described circular groove is 8-15mm.
After adopting such scheme, the beneficial effects of the utility model are: the utility model changes original lubrication oil circulation loop, by at ring gear, hub and back shaft offer spill port, passage too small susceptible to plugging problem when solving oil return, lubricant oil refluxes from friction plate group oil outlet end, successively through ring gear spill port, circular groove, hub spill port and back shaft spill port are back in driving axle housing intracoelomic cavity, make oil circuit more smooth and easy, avoid high oil temperature, easily make the Sealing in rim brake impaired, even lubricant oil mixes with brake fluid, the series of problems such as deterioration of lubricant, reduce the generation of brake troubles.
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
