Abstract
The utility model discloses a sealing structure of a vehicle drive axle. The sealing structure comprises a first framework oil seal and a second framework oil seal, wherein the first framework oil seal, a first gasket, a first tapered roller bearing, a second tapered roller bearing, the second framework oil seal and a second gasket are arranged between an axle sleeve and a hub from the end to the middle in sequence, the first framework oil seal and the first gasket are located at the outer end of the first tapered roller bearing, the first gasket is sleeved on the axle sleeve, the first framework oil seal is sleeved on the first gasket, an O-shaped seal ring is also arranged in the first gasket, the second framework oil seal and the second gasket are located at the inner end of the second tapered roller bearing, the second gasket is sleeved on the axle sleeve, and the second framework oil seal is sleeved on the second gasket. The structure of the utility model is simple, and a first barrier consists of the first framework oil seal and the O-shaped seal ring, so that the gear oil is separated in time, the problem that the gear oil leaks is solved, and the sealing performance is improved.
Description
Technical field
The utility model relates to the technical field of vehicle drive axle, special relevant with a kind of vehicle drive axle sealing configuration.
Background technique
Vehicle drive axle is generally made up of main reducing gear, differential mechanism, wheel drive and driving axle housing etc.The end of ransaxle in Power Train, its effect is that the engine torque that universal driving device is transmitted passes to driving wheel by main reducing gear, differential mechanism, semiaxis etc., realizes reduction of speed and increases torque; And by the direction of transfer of main reducing gear taper gear pair change torque; Also realize both sides wheel differential action by differential mechanism, ensure that medial and lateral wheel turns to different rotating speeds; Realize carrying and intermal force by axle housing body and wheel simultaneously.
In prior art, ransaxle as shown in Figure 1, on semiaxis 10, cover has axle sleeve 70, at the two ends of axle sleeve 70, cover has wheel hub 80, wheel hub 80 is also fixedly mounted on the two ends of semiaxis 10, between axle sleeve 70 and wheel hub 80, be provided with successively seal ring 30 to centre by end, the first tapered roller bearing 20, the second tapered roller bearing 40, outside framework oil seal 50 and packing ring 60, seal ring 30 and outside framework oil seal 50 form ransaxle sealing configuration, seal ring 30 is positioned at the outer end of the first tapered roller bearing 20, outside framework oil seal 50 and packing ring 60 are positioned at the inner of the second tapered roller bearing 40, packing ring 60 is enclosed within on axle sleeve 70, outside framework oil seal 50 is enclosed within on packing ring 60.Because the sealing of seal ring 30 is not good enough, this makes existing ransaxle sealability entirety unsatisfactory, causes gear oil very easily to leak to break, makes braking failure.
In view of this, the inventor improves ransaxle sealing configuration specially, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of vehicle drive axle sealing configuration, with lift-off seal performance.
To achieve these goals, the technical solution of the utility model is as follows:
Vehicle drive axle sealing configuration, comprise the first outside framework oil seal and the second outside framework oil seal, between axle sleeve and wheel hub, be provided with successively the first outside framework oil seal to centre by end, the first packing ring, the first tapered roller bearing, the second tapered roller bearing, the second outside framework oil seal and the second packing ring, the first outside framework oil seal and the first packing ring are positioned at the outer end of the first tapered roller bearing, the first gasket sleeve is on axle sleeve, the first outside framework oil seal is enclosed within on the first packing ring, in the first packing ring, be also provided with O RunddichtringO, the second outside framework oil seal and the second packing ring are positioned at the inner of the second tapered roller bearing, the second gasket sleeve is on axle sleeve, the second outside framework oil seal is enclosed within on the second packing ring.
The surface of contact of described the first packing ring and axle sleeve forms groove, and O RunddichtringO is arranged in groove.
Adopt after such scheme, the utility model is simple in structure, change the seal ring of the first tapered roller bearing outer end into first outside framework oil seal, and increase is positioned at the O RunddichtringO of the first packing ring, form the first barrier by the first outside framework oil seal and O RunddichtringO, gear oil is kept apart in time, solve the leakage problem of gear oil, lift-off seal performance.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.
Brief description of the drawings
Fig. 1 is the structural representation of prior art ransaxle;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is partial enlarged drawing of the present utility model.
Drawing reference numeral explanation

Embodiment
As shown in Figures 2 and 3, be preferred embodiment of the present utility model.
A kind of vehicle drive axle sealing configuration that the utility model discloses, comprises the first outside framework oil seal 1 and the second outside framework oil seal 2.
Between axle sleeve 70 and wheel hub 80, be provided with successively the first outside framework oil seal 1, the first packing ring 3, the first tapered roller bearing 20, the second tapered roller bearing 40, the second outside framework oil seal 2 and the second packing ring 4 to centre by end.
The first outside framework oil seal 1 and the first packing ring 3 are positioned at the outer end of the first tapered roller bearing 20, the first packing ring 3 is enclosed within on axle sleeve 70, the first outside framework oil seal 1 is enclosed within on the first packing ring 3, in the first packing ring 3, be also provided with O RunddichtringO 5, stablize for ease of assembly O RunddichtringO 5 and after making assembling, this embodiment forms groove 31 at the first packing ring 3 and the surface of contact of axle sleeve 70, and O RunddichtringO 5 is arranged in groove 31.
The second outside framework oil seal 2 and the second packing ring 4 are positioned at the inner of the second tapered roller bearing 40, and the second packing ring 4 is enclosed within on axle sleeve 70, and the second outside framework oil seal 2 is enclosed within on the second packing ring 4.
The utility model forms the first barrier by the first outside framework oil seal 1 and O RunddichtringO 5, and gear oil is kept apart as early as possible, avoids the leakage problem of gear oil, lift-off seal performance.
