Abstract
The invention discloses a double-rear driving axle hub and a hub assembly thereof. The double-rear driving axle hub comprises a hub body provided with an axle hole; two axial ends along the axle hole are provided with an inner bearing hole and an outer bearing hole; the radial periphery of the hub body is provided with wheel flanges and brake drum flanges at intervals along the axial direction; and strengthening ribs are connected between the wheel flanges and the brake drum flanges. An axle tube is arranged in the axle hole; an inner bearing and an outer bearing are arranged in the inner bearing hole and the outer bearing hole between the hub body and the axle tube; the other end of the axle tube is connected with an axle case; an axle shaft driving the hub body to rotate is arranged in the axle tube; the wheel flanges are provided with wheels through bolts; and the brake drum flanges are provided with brake drums through bolts. The double-rear driving axle hub can solve the problems of unreasonable stress of bearings and no universality of the wheels of a whole vehicle when a single wheel is assembled in the prior driving axle hub.
Description
Technical field
The present invention relates to a kind of double-rear driving axle wheel hub and Hub assembly thereof that assembles single wheel.
Background technology
Traditional two drive axle wheel hub assembling dual wheels, be 4 wheels of assembling on a vehicle bridge, 2 at every end, (vehicle bridge is assembled 2 wheels when the full car general-duty single wheel of assembling, 1 at every end), only be provided with a flange on the wheel hub, wheel by bolts assemblies in the flange outside, brake wheel then by bolts assemblies in the flange inboard.The subject matter that the wheel hub of this pattern structurally exists is: during the assembling single wheel, between the tire axial centre plane impassabitity two wheel hub bearings, shaft strength is unreasonable, and line of action of force is near inboard bearing, and the inboard bearing life-span is low; Full car wheel is not general, and front and back bridge wheel can not exchange; Hub end exceeds the tire outer face, and crossing ability is poor, and the unloading hub end of the time easily damaging.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of double-rear driving axle wheel hub, has problems such as the unreasonable and full car wheel of shaft strength is not general to overcome existing drive axle dress wheel hub when joining single wheel.
Another technical matters that the present invention will solve provides a kind of double-rear driving axle Hub assembly.
For solving first technical matters of the present invention, the present invention includes hub body, described hub body has axis hole, be provided with neck bearing hole, outer bearing hole along the axial two ends of axis hole, its constructional feature is to be provided with wheel flange, brake wheel flange at hub body outer radial periphery face upper edge axially spaced-apart.
As improvement of the present invention, between wheel flange and brake wheel flange, be connected with reinforced rib; Described reinforced rib is provided with on the outer peripheral face of the hub body between wheel flange and the brake wheel flange at interval.
For solving second technical matters of the present invention, in described axis hole, axle tube is installed, in neck bearing hole between hub body and axle tube and the outer bearing hole neck bearing, outer bearing are installed, the other end of described axle tube is connected to axle housing, and the semiaxis that the drive hub body rotates is installed in the axle tube; On the wheel flange, wheel is installed, on the brake wheel flange, brake wheel is installed by bolt by bolt.
After adopting said structure, owing on wheel hub, be provided with two independently flanges (wheel flange, brake wheel flange), when the assembling single wheel, can guarantee that the tire axial centre plane is between two hub bearings, line of action of force is between inside and outside two bearings, to guarantee the stressed reasonable distribution of bearing, bearing life improves; Can guarantee that full car wheel is general, front and back bridge wheel exchanges; Wheel hub is in the tire outer face, and crossing ability is good, safety.Between wheel flange and brake wheel flange, be connected with reinforced rib, can increase the intensity of two flanges.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Fig. 1 is a mounting structure scheme drawing of the present invention;
Fig. 2 is the axial arrangement scheme drawing of wheel hub among Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
With reference to Fig. 2, Fig. 3, this double-rear driving axle wheel hub comprises hub body 1, hub body 1 has axis hole 13, is provided with neck bearing hole 14, outer bearing hole 15 along axis hole 13 axial two ends, is provided with wheel flange 8, brake wheel flange 9 at hub body 1 outer radial periphery face upper edge axially spaced-apart.On the outer radial periphery face of the hub body 1 between wheel flange 8 and the brake wheel flange 9, be connected with reinforced rib 16 at interval, this reinforced rib 16 can be made as many according to designing requirement or operating needs, the reinforced rib 16 of many interval settings is along the radially scattering and the rectangular distribution of hub body 1, link together with wheel flange 8 and brake wheel flange 9 relative inner end surfaces at axial two ends, to increase the intensity of two flanges.
Double-rear driving axle Hub assembly shown in Figure 1, be that axle tube 4 is installed in axis hole 13, in neck bearing hole 14 between hub body 1 and axle tube 4 and the outer bearing hole 15 neck bearing 2, outer bearing 3 are installed, the other end of axle tube 4 is connected to axle housing 5 by interference fit, the semiaxis 6 that drive hub body 1 rotates is installed in the axle tube 4, and semiaxis links to each other with wheel hub by bolt.On wheel flange 8, wheel 10 is installed, on brake wheel flange 9, brake wheel 11 is installed by bolt 12 by bolt 7.
