Embodiment Construction

[0017] Below by embodiment, in conjunction with accompanying drawing, the present invention is described in further detail:

[0018] Such as figure 1 Shown is a cantilever mounting structure for an automobile sub-frame, the main body of which is the sub-frame 1, which is a left-right symmetrical piece welded by a plurality of steel plates.

[0019] Such as figure 2 As shown, cavities are symmetrically arranged on the left and right sides of the sub-frame 1 , and the cavities are surrounded by steel plates constituting the sub-frame 1 . A mounting plate 2 is arranged longitudinally in the cavity, and the mounting plate 2 divides the cavity into a front cavity 1a and a rear cavity 1b. A rectangular cover 3 is welded on the mounting plate 2, and the rectangular cover 3 is located in the rear cavity 1b, that is, the rectangular cover 3 is welded on the plane of the mounting plate 2 located in the rear cavity 1b. A movable nut 4 is housed in the rectangular cover 3 , and the a...

Abstract

The invention discloses a cantilever installation structure of an automotive auxiliary frame. The left and right sides of the auxiliary frame (1) are symmetrically provided with cavities, mounting plates (2) are longitudinally arranged in the cavities, a rectangular cover (3) is welded on the mounting plates (2), movable nuts (4) are arranged in the rectangular cover (3), the axes of the movable nuts (4) are vertical to the mounting plates (2), and the movable nuts (4) can move in the radial direction in the rectangular cover (3). The structure is simple, an automotive cantilever can be installed on the auxiliary frame easily and quickly at one step, and the assembly defect of regulation incapability in the conventional projection welding nut connection modes is not caused.

Description

technical field [0001] The invention relates to an automobile auxiliary frame, in particular to an automobile auxiliary frame structure for installing a cantilever. Background technique [0002] The sub-frame of the car is equivalent to the skeleton of the front and rear axles and is an integral part of the front and rear axles. In the traditional load-bearing body without subframe, its cantilever is directly connected with the steel plate of the body. After the birth of the sub-frame, the front and rear cantilevers can be assembled on the sub-frame first to form an axle assembly, and then this assembly is installed on the body together to make the car chassis more comfortable and controllable. [0003] Such as Figure 4 As shown, the automobile subframe 1 is welded by a plurality of steel plates, a mounting plate 2 is welded in the cavity of the subframe 1, and a projection welding nut 5 is arranged on the mounting plate 2, and the mounting plate 2 and the subframe 1 are ...
