Abstract

The invention belongs to the technical field of automobile accessories, and particularly relates to a novel rear lower spring arm. The novel rear lower spring arm comprises a left arm, a right arm anda back board, wherein the bottom of the left arm is welded to the back board; the top of the back board is welded to the right arm; the top of the left arm is connected with a left arm inclination board through integral forming; the left side wall of the left arm inclination board is provided with a left arm hole; and the top of the right arm is connected with a right arm inclination board through integral forming. By use of the novel rear lower spring arm, through the combined utilization of accessories, an amount of parts can be effectively reduced, integral weight is lowered, a bushing pressurization technology is omitted, and cost can be effectively lowered after steps are reduced. On a basis that the left arm and the right arm are fixed through the back board, a main inclination frame and an auxiliary inclination frame are added, after a main axle block and an auxiliary axle block are installed with the main inclination frame and the auxiliary inclination frame, the spring is used for elastically connecting the main axle block and the auxiliary axle block, a pressure relief and buffering capability can be effectively improved, the own strain force of the rear lower spring armis improved, and stability is improved.

Description

Technical field

[0001] The invention relates to the technical field of vehicle accessories, in particular to a new type of rear lower spring arm. Background technique

[0002] Cars are powered by power and have 4 or more wheels on off-track vehicles. They are mainly used for: carrying people and goods; traction and carrying people and goods; special purposes.

[0003] In the current automotive suspension field, the chassis structural parts play a key role in the performance of the car. Among the rear suspension structural parts, the rear lower spring arm is the most important in addition to the rear subframe. At this stage, the rear When the lower spring arm and the rear sub-frame frame are assembled, the bushing suit is often used. The structure often used is that the bushing is fitted to one end of the rear lower spring arm and then assembled to the rear sub-frame.

[0004] At present, for the traditional lower spring arm structure, the number of parts is large and the overall wei...

Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0016] The present invention provides a new rear lower spring arm. Through the combined use of accessories, the processing steps are reduced and the resistance is increased. Please refer to Figure 1-3 , Including left arm 100, right arm 200 and back plate 300;

[0017] See again figure 1 , The top of the left arm 100 has a left arm sloping plate 110, specifically, the top of the left arm 100 is integrally formed with the left arm sloping p...
