[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Among Fig. 1 to Fig. 5: axle housing 10, axle housing stage casing 11, welding connecting hole 111, shaft orientation reinforcing rib 112, circumference reinforced rib 113, first tapped blind hole 114, second tapped blind hole 115, axle tube 12, flange 13, main reduction gear 20, axle housing bonnet 30, drg 40, bolt 50.
As Fig. 1, Fig. 3, shown in Figure 5, a kind of minicar back axle, comprise axle housing 10 and main reduction gear 20, described axle housing 10 is provided with first tapped blind hole 114, described main reduction gear 20 is provided with and described first tapped blind hole, 114 corresponding through hole (not shown)s, and described axle housing 10 links to each other by bolt 50 with described main reduction gear 20.Axle housing 10 and main reduction gear were arranged in 20 minutes, no matter be that axle housing 10 or main reduction gear 20 damage, can change cost saving separately; First tapped blind hole 114 of axle housing 10 can avoid back axle in axle housing 10 leakage of oils, makes bolt 50 be difficult for getting rusty, increasing the life-span again.
As Fig. 1, Fig. 3, shown in Figure 5, also be provided with axle housing bonnet 30, described axle housing 10 is provided with second tapped blind hole 115, described axle housing bonnet 30 is provided with and described second tapped blind hole, 115 corresponding through hole (not shown)s, and described axle housing 10 links to each other by bolt 50 with described axle housing bonnet 30.Axle housing bonnet 30 makes axle housing 10 sealing, and axle housing bonnet 30 can disassemble, and the state in the back axle is checked maintenance.Second tapped blind hole 115 of axle housing 10 can avoid back axle in axle housing 10 leakage of oils, makes bolt 50 be difficult for getting rusty, increasing the life-span again.
As shown in Figure 2, described axle housing 10 comprises axle housing stage casing 11, axle tube 12 and flange 13, described axle housing stage casing 11 is the integral type casting, described axle tube 12 1 ends are pressed into described axle housing stage casing 11, be interference fit between described axle housing stage casing 11 and the described axle tube 12, described axle tube 12 other ends and 13 welding of described flange, flange 13 links to each other with drg 40, described axle housing stage casing 11 is provided with welding connecting hole 111, described axle housing stage casing 11 and described axle tube 12 are fixed by welding connecting hole 111 top plug solid weldings, this makes described axle housing stage casing 11 and described axle tube 12 fixing-stables, and with low cost.
