Description

Front stabilizer bar mounting structure and vehicle having same

technical field

The utility model relates to the technical field of vehicle frame structures, in particular to a front transverse stabilizer bar installation structure and a vehicle with the same.

Background technique

The role of the stabilizer bar is to prevent the body of the vehicle from excessive lateral roll when turning, with the purpose of preventing the vehicle from rolling over and improving ride comfort. There are two main installation structures for the front stabilizer bar in existing vehicles. The first is to install the front stabilizer bar on the upper plate of the front subframe. This structure requires the upper plate of the subframe to provide a mounting position for the stabilizer bar and to The flatness of the installation surface at the installation position is relatively high. The front stabilizer bar is usually directly installed to the upper plate of the front subframe by using a clip set and other matching bolts and nuts. Usually, the bolts need to be welded to the front subframe in advance. On the bottom surface of the upper plate, then weld the upper plate and the lower plate of the front subframe, and then use the bolts and nuts to connect the clip set to the upper plate of the front subframe, so as to complete the front stabilizer bar. Installation, during the installation process, the coaxiality of the nuts is highly required, and a separate process is required to install the front stabilizer bar, which will increase the man-hours and cost of the line body, and this front stabilizer bar installation structure still exists The nuts located between the upper plate and the lower plate of the front subframe cannot be repaired after falling off, and the front suspension system needs to be disassembled during maintenance, making maintenance difficult; the second is to weld the bracket on the front subframe separately. For the installation of the front stabilizer bar, the separate welded bracket provides the installation position for the front stabilizer bar, and the front stabilizer bar is installed on the separate welded bracket through matching mounting bolts and nuts, which also exists during the installation process. There is a high requirement on the coaxiality of the nuts, and a separate process is required for the installation of the front stabilizer bar, such as the installation of separate welding brackets and nuts and bolts, which will increase the man-hours and costs of the line body, and this The front stabilizer bar installation structure also has the problem that the separate welded bracket will increase the weight of the sub-frame, which is not conducive to the lightweight of the frame.
