Automobile rear axle assembly with adjusting arm convenient to disassemble, assemble and adjust

Abstract

The invention discloses an automobile rear axle assembly with an adjusting arm convenient to disassemble, assemble and adjust, which relates to an automobile rear axle assembly. The automobile rear axle assembly comprises a rear axle shell assembly, a main reducing assembly, a brake assembly, a hub assembly, a brake air chamber, the adjusting arm and a half-moon-shaped adjusting support. An arc-shaped adjusting groove is formed in the half-moon-shaped adjusting support, and the half-moon-shaped adjusting support is directly fixed to the air chamber support through the arc-shaped adjusting groove by means of a fastener. A stop pin is further installed on the half-moon-shaped adjusting support and penetrates into a pin hole of the control arm control support of the adjusting arm. The installation clearance angle of the adjusting arm can be adjusted at different positions of the arc groove through the fastener, and the assembly can be suitable for installation clearance angles of variousadjusting arms; the half-moon-shaped adjusting support is directly fixed on the air chamber support, so that a bracket fixing seat does not need to be additionally arranged; and the stop pin directlypenetrates into the pin hole of the control arm control bracket of the adjusting arm, so that the installation is simple, the disassembly is easy, the operation process and the production cost can bereduced, the after-sales maintenance cost is reduced, and the popularization and the use are easy.
