Abstract
A method for manufacturing a rear axle includes: a brake flange press-fitting step of press-fitting a brake flange to an outer peripheral surface of a rear axle housing; a brake flange welding step of welding the rear axle housing and the brake flange; an axle end press-fitting step of press-fitting an axle end to an inner peripheral surface of an end portion of the rear axle housing; and an axle end welding step of welding the rear axle housing and the axle end.
Claims7
A method for manufacturing a rear axle comprising:
- press-fitting a brake flange to an outer peripheral surface of a rear axle housing;
- welding the rear axle housing and the brake flange;
- press-fitting an axle end to an inner peripheral surface of an end portion of the rear axle housing;
- and
- welding the rear axle housing and the axle end,
- wherein, in the welding of the rear axle housing and the brake flange, a melt zone is formed in a gap between the rear axle housing and the brake flange by an arc generated by energizing an electrode, and before the melt zone is cured, a first subsequent wire is supplied to the melt zone without being energized, and
- wherein, in the welding of the rear axle housing and the axle end, a melt zone is formed in a gap between the rear axle housing and the axle end by an arc generated by energizing an electrode, and before the melt zone is cured, a second subsequent wire is supplied to the melt zone without being energized.
A method for manufacturing a rear axle comprising:
- forming a reduced-diameter portion having an outer circumference of a reduced diameter at the end portion of a rear axle housing;
- press-fitting a brake flange to an outer peripheral surface of a rear axle housing after forming the reduced-diameter portion;
- welding the rear axle housing and the brake flange;
- press-fitting an axle end to an inner peripheral surface of an end portion of the rear axle housing;
- and
- welding the rear axle housing and the axle end such that the axle end is peripherally enclosed by the welding.
