Longitudinal supporting frame of automobile transverse stabilizing bar

Abstract

The invention discloses a longitudinal supporting frame of an automobile transverse stabilizing bar. The longitudinal supporting frame comprises a longitudinal supporting frame body with the U-shaped cross section, an omega-shaped clamping hoop is connected to the front end of the longitudinal supporting frame body, the clamping hoop is formed in the mode that the bottom face of the longitudinal supporting frame body forwards extends, and an outward turning edge is arranged at the back end of the longitudinal supporting frame body. A strengthening piece provided with the U-shaped cross section and formed by sheet metal parts in a whole stamping mode is arranged in the longitudinal supporting frame body, the front end of the strengthening piece is welded with the arc face of the clamping hoop, and the two sides of the strengthening piece are welded with the two sides of the longitudinal supporting frame body. The longitudinal supporting frame is high in strength and good in bearing capacity, and can solve the problems of deformation and weld failures in the using process.

Description

technical field [0001] The invention relates to auto parts, in particular to a longitudinal support frame of an automobile lateral stabilizer bar. Background technique [0002] The longitudinal support frame of the automobile stabilizer bar is generally used in ordinary economical cars to fix the stabilizer bar and form an installation support between the lower beam of the water tank and the rear of the engine room, which is a crucial part of the car. When the vehicle rolls and brakes, the longitudinal support frame will bear a large load impact, so it needs to have sufficient fatigue durability. [0003] The longitudinal support frame of the existing automobile stabilizer bar mainly has two structures: one is a bracket (equivalent to the longitudinal support frame) under the engine compartment of the automobile disclosed by the patent with the publication number CN101722992B, which consists of the bracket body ( Equivalent to the body of the longitudinal support frame) and...

Problems solved by technology

[0003] The longitudinal support frame of the existing automobile stabilizer bar mainly has two structures: one is a bracket (equivalent to the longitudinal support frame) under the engine compartment of the automobile disclosed by the patent with the publication number CN101722992B, which consists of the bracket body ( Equivalent to the body of the longitudinal support frame) and the mounting plate of the horizontal stabilizer bar (equivalent to the Ω-shaped clamp), the bracket body is made of seamless steel pipe, its two ends are flattened and equipped with assembly holes, and the mounting plate of the horizontal stabilizer bar is welded At the front end of the bracket body, the structural integrity is poor, and the strength of the bracket body is weakened after being flattened, and the connection strength with the stabilizer bar mounting plate is poor, and there is welding stress between the stabilizer bar mounting plate and the front end of the bracket body. It will also affect the fatigue durability of the lower bracket

The other is made of two stamping plates, buckled and welded up and down. This structure has complex process, high material and manufacturing costs, and the welding length is long, the welding quality is not easy to control, and the weld is easy to crack. Through CAE analysis It is found that there are many high stress concentration areas in the weld seam, and deformation and cracking of welding parts often occur in the later use process, thus affecting the fatigue durability of the whole vehicle
