[0012] Figure numerals: inner bearing mounting position 1, rim bolt mounting seat 2, brake drum mounting position 3, reinforcing rib 4, rim mounting spoke 5, T-shaped protrusion 6, U-shaped weight-reducing groove 7, threaded hole 8, outer bearing mounting position 9. DETAILED DESCRIPTION

[0013] The specific implementation manner of the loader optimized drive axle wheel hub of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] Figure 1-Figure 2 As shown, the utility model is a loader optimized drive axle wheel hub comprising an inner bearing mounting position 1, a rim bolt mounting seat 2, a brake drum mounting position 3, a reinforcing rib 4, a rim mounting spoke 5, a T-shaped protrusion 6, a U-shaped weight-reducing groove 7, a threaded hole 8 and an outer bearing mounting position 9; the outer circumferential wall thickness of the inner bearing mounting position 1 of the wheel hub is thinned from the original 10mm to 7mm, and the thickness of the brake drum mounting position 3 is thinned from the original 10mm to 5mm; a U-shaped weight-reducing groove 7 is provided on the outer circle of the outer bearing mounting position 9 of the wheel hub, and there are a total of 10 U-shaped weight-reducing grooves 7, which are evenly distributed, and the depth of each U-shaped weight-reducing groove 7 is 60mm; 4 T-shaped protrusions 6 are evenly provided on the brake drum mounting position 3 along the circumferential direction, and 12 reinforcing ribs 4 are evenly provided along the circumferential direction at the connection transition between the outer circle of the inner bearing mounting position 1 of the wheel hub and the brake drum mounting position 3, and 4 of the reinforcing ribs 4 are on the same axis as the 4 T-shaped protrusions 6.

[0015] The loader optimized drive axle wheel hub of the above structure reduces the weight of the wheel hub by reducing the outer circumferential wall thickness of the inner bearing mounting position 1 of the wheel hub from 10 mm to 7 mm, and reducing the thickness of the brake drum mounting position 3 from 10 mm to 5 mm; 12 reinforcing ribs 4 are provided at the transition between the outer circumference of the inner bearing mounting position 1 of the wheel hub and the brake drum mounting position 3 to ensure the strength of the outer circumference of the inner bearing mounting position 1 of the wheel hub after thinning; 4 T-shaped protrusions 6 are added to the brake drum mounting position 3 to ensure that the installation of the brake drum is not affected and the strength of the brake drum when working; 10 threaded holes 8 are provided on the outer circumferential side of the outer bearing mounting position 9 of the wheel hub for connecting the half-axles, so the whole part is relatively thick. By adding a U-shaped weight-reducing groove 7 between each two adjacent threaded holes 8, the weight of the wheel hub can be further reduced, material consumption can be reduced, and economic benefits can be improved.
