Casting type guide arm for air suspension

Abstract

The casting type guide arm comprises a guide arm body, an upper supporting plate, a lower supporting plate and an air bag mounting support, the upper supporting plate is located at the bottom end of the guide arm body and integrally cast with the guide arm body, and the lower supporting plate is located on one side of the air bag mounting support and integrally cast with the air bag mounting support. The upper supporting plate and the lower supporting plate are connected through a connecting assembly. The structure is of a casting type and is different from a traditional integral forging type, and the weight of a single guide arm is greatly reduced while the integral strength is guaranteed; the upper supporting plate and the guide arm body are cast into a whole, and the lower supporting plate and the guide arm support are cast into a whole, so that the coordination of the air suspension assembly is effectively ensured; the air bag mounting support has a deviation angle, so that when the air bag is mounted, the air bag is always in the center of the lower supporting plate, the air bag is uniformly stressed, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of guide elements for air suspension, in particular to a cast guide arm for air suspension. Background technique [0002] Due to its unique advantages, air suspension is more and more widely used in lightweight commercial vehicles, and the air suspension system is also developing in the direction of light weight. The guide arm, as the guide element in the air suspension system, plays a role Bearing and guiding functions, the traditional guide arm mostly adopts an integral forged structure, and the integrated guide arm made of spring steel has the problems of bulky body and poor coordination. Contents of the invention [0003] The object of the present invention is to provide a cast guide arm for an air suspension to solve the above problems. [0004] The present invention solves technical problem and adopts following technical scheme: [0005] A cast guide arm for an air suspension, comprising: a guide a...
