Embodiment Construction

[0030] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, in order to realize the purpose of structural optimization and lightweight design, the present invention provides a kind of automobile front sub-frame, comprises the front sub-frame upper board 10 and the front sub-frame lower board 20 that are mated with each other, wherein the front sub-frame Both sides of the upper plate 10 of the frame are respectively provided with a stabilizer bar mounting plate 30, and each stabilizer bar mounting plate 30 is provided with a mounting hole 31 for installing the stabilizer bar 50 (such as figure 2 and Figure 4 shown), and the space between each stabilizer bar mounting plate 30 and the front sub-frame lower plate 20 is suitable for placing one end of the swing arm 60, so that one end of the swing arm 60 and the stabilizer bar 50 pass through a common fastener S (such as a bolt ) through the mounting hole 31 for installation.

[0031] In this embodiment, the stabi...

Abstract

The invention provides an automobile front auxiliary frame and a corresponding automobile. The automobile front auxiliary frame comprises a front auxiliary frame upper plate and a front auxiliary frame lower plate which are in matched connection with each other. Stabilizing rod mounting plates are arranged on two sides of the front auxiliary frame upper plate respectively, every stabilizing rod mounting plate is provided with a mounting hole for installing a stabilizing rod, a space between every stabilizing rod mounting plate and the front auxiliary frame lower plate is suitable for placing one end of a swing arm, and the end of the swing arm and the stabilizing rods are installed by utilizing a shared fastener to penetrate the mounting holes. The automobile front auxiliary frame is suitable for a Macpherson suspension; compared with other auxiliary frames, the number of installed and welded sheet metal parts is reduced, the stabilizing rods and the swing arm share assembling bolts, use of welding fasteners is reduced, assembling fasteners of a whole front suspension are reduced, the structure is lightened, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile front auxiliary frame and a corresponding automobile. Background technique [0002] The front sub-frame is an important part of the car chassis and is used in the front suspension system of the car. The front sub-frame in the traditional McPherson suspension is connected with the body at four points, and its shape is mostly π-shaped, as a stable Rods, steering gear, engine mounts, swing arms and other components provide important support structures for the installation location. Since the subframe is a key force-bearing component, its force is complex, and it is usually designed as a hollow section of different shapes and sizes, which is assembled and welded by stamping parts of different thicknesses. In order to ensure sufficient strength and rigidity, many reinforced welding components are often used, resulting in more welding processes for the entire subfram...
