The utility model is through above-mentioned improvement, and its effect and effect are:
1. provide preferably axle housing of a kind of stiffness: adopt to change the axle housing cross section and change the stiffness that the poor mode that subtracts the big R size between the maximum cylindrical of assembly place tooth bag and the axle housing square-section increases axle housing. Originally be (158) about the square-section * (about) 158 * (thickness) 13 changed over about (160) * (about) 150 * (thickness) 13 to 16, the big R size that difference subtracts between the maximum cylindrical (seeing shown in Fig. 3) of assembly place tooth bag and the axle housing square-section was R200 originally, be R250 after changing), improve the stiffness of axle housing, thereby effectively prevent in the transportation because the axle housing degree of disturbing that overload causes increase and the phenomenon that fractures. Reach simultaneously and make axle housing as the key safety part, the purpose that axle tube takes second place makes axle tube give full play to service life.
2. provide a kind of and subtracted the axle housing structure that assembly is complementary with 457 type differences: the axle housing middle part is provided with installs inner stopper, the male half coupling that 457 type differences subtract assembly, Chinese lute hole, the breach of dodging driven gear, the 457 type differences that distribute by respective angles and distribution circle subtract assembly and axle housing installed surface to the center height of the distance at axle housing center, consist of standard 457 speed reducer assembly interfaces, thereby 457 type differences have been subtracted assembly and axle housing is complementary. Break original 153 axle housings and can not subtract the design limitation that assembly is complementary with 457 type differences, can improve the vehicle climbing capacity, satisfied the instructions for use of vehicle under various operating modes.
3. provide a kind of connect with axle housing be complementary, with the axle tube of former 153 type axle assembly same-interfaces: be axle tube at the two ends of described axle case assy, the size that comprise the screw thread specification, axle-shaft oil seal gear, inner bearing gear, outer bearing gear, oil seal washer mounting block of locking nut, is complementary with the brake installation is, and the weld size system that is complementary of body etc. Wherein inner bearing gear and outer bearing gear cooperate the hub assembly assembling to use together; Oil seal washer mounting block between inner bearing gear and axle tube cooperates oil seal washer, axle tube, hub assembly assembling to use; The axle-shaft oil seal gear cooperates axle tube, semiaxis assembling to use; With brake the size system that is complementary being installed cooperates brake interface size to connect use; Cooperate body, grommet welding requirements to use with the weld size system that body is complementary. Thereby other parts of the two ends of 153 enhanced type axle case assys and 153 organically are combined and installed together, avoided since the variation of axle tube that bring with not generalizations other parts, most importantly solved the interface that is complementary with this axle housing. Also broken simultaneously original 153 axle tubes can not with the cross section design limitation of axle housing welding coupling of back axle that changes, and make from now on more flexibleization of design.
4. passage, the excellent position dimension of purge cock Kongzui are provided: the design size of this passage, the excellent position of purge cock Kongzui is to get the scheme that draws after verifying through bench test, preventing test again by aerodynamics, hydrodynamics design. Thereby the axle case assy that the random design in the position that has effectively solved former pore causes oil leakage phenomenon inner and inner and that the outside pressure skewness causes; The position randomness that has effectively solved former purge cock designs the leakage of oil that the plug screw that causes comes off, becomes flexible and causes, finally burn the part phenomenons such as principal and subordinate, moving gear, can be the effectively discharges such as iron rust of the abrasive dust of the driving and driven gear movement generation of axle case assy inside, decelerator generation.
5. provide the design reference that welds between a kind of axle housing and axle tube, grommet criterion: the form of welding design between axle housing, axle tube, the grommet with formula showed, design criteria is provided for later design.
