[0003] The design of this structural assembly is too complex. There are as many as 12 kinds of various components with different structures, different designs, and different materials, which increases the difficulty of production and manufacturing and the difficulty of ensuring production consistency. At the same time, it increases the production, manufacturing, and procurement costs of the whole vehicle and does not meet the design requirements of the whole vehicle for lightweight; in addition, the reinforcing R-piece 1, the reinforcing R-piece 2, the right-side connecting piece, and the left-side connecting piece in this assembly structure are structural parts formed by die stamping, which exacerbates the cost of vehicle model design and development and also requires bearing the costs such as developing dies. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a fixing seat for a transverse thrust rod of a front suspension based on an 11-meter full-load-bearing bus.

[0005] The technical solution adopted by the utility model is that for the fixing seat of the transverse thrust rod of the front suspension based on an 11-meter full-load-bearing bus, it includes a base with an n-shaped groove structure. A rectangular tube crossbeam is welded along the length direction at the center of the top end surface of the base. The transverse thrust rod fixing seat body is welded inside the front end of the base, and the right fixing seat of the front suspension transverse thrust rod is welded at the rear end of the base. Installation hole positions corresponding to the front suspension transverse thrust rod are opened on both the transverse thrust rod fixing seat body and the right fixing seat of the front suspension transverse thrust rod.

[0006] Preferably, reinforcing R-pieces are welded on both the left and right sides at both ends of the above-mentioned rectangular tube crossbeam.

[0007] Preferably, reinforcing plates I and II are symmetrically welded to the inner and outer sides of the above-mentioned thrust rod fixing seat near both ends respectively. The reinforcing plates I and II are triangular, and the right-angled sides at the top are welded to the base.

[0008] Preferably, the main body part of the fixing seat on the right side of the above-mentioned front suspension lateral thrust rod is arc-shaped, and a table surface for installing the front suspension lateral thrust rod is provided on the back surface. The top and the top end are round tables provided with mounting holes.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1) For the front suspension lateral thrust rod fixing seat provided by the present utility model, there are only 6 parts, and the reinforcing R part among them is a borrowed part that has been developed and designed for the previous models. Therefore, there are only 5 newly designed parts, which improves the production and manufacturing efficiency and the guarantee ability of production consistency. At the same time, it reduces the production, manufacturing and procurement costs of the whole vehicle, meeting the design goal of vehicle lightweighting.

[0011] 2) The structural parts formed without die stamping further reduce the cost of vehicle model design and development. At the same time, there is no need to bear the costs such as developing dies.

[0012] 3) The structural design is simple and reliable. The body of the lateral thrust rod fixing seat is wrapped inside the base, and reinforcing plates are designed on both its left and right sides, so that there are no force-bearing defects in its overall structure, effectively ensuring the reliability of this new structure in use.
