Lorry stamping and welding balanced suspension

Abstract

The invention discloses a lorry stamping and welding balanced suspension. An original forging bent shaft is changed into the structure that the two sides of a support are each provided with a straight shaft, round steel is adopted for blanking, forging is not needed, and therefore heat treatment is easy and convenient, the hardening and tempering quality is high, the coaxiality is stable, and the original forging cost and input are greatly reduced; an original forging bent shaft connecting support is changed into a welding balance beam for connection, and therefore stress is not totally concentrated to the shaft and is decomposed to a welding balance beam on the upper face, a frame structure is formed after installation with an automotive frame, and several times of load bearing capacity is strengthened; and an original casting support is changed into the manner that a steal plate is used for completing stamping welding, the casting defects and the tradition problem of support tearing caused by uneven wall thickness are avoided, the original casting and machining cost is greatly reduced. According to the lorry stamping and welding balanced suspension, welding is achieved through steel plate stamping, the wall thickness is guaranteed, the light aim is achieved, the forging bent shaft is replaced with the balance beam to form the frame structure, the product achieves overall stress, and full load bearing can be achieved under any complex road condition.

Description

technical field [0001] The invention relates to the field of industrial manufacturing, in particular to a stamping and welding balance suspension for a truck. Background technique [0002] As the country attaches great importance to environmental protection, the pollution of foundries has brought huge harm to people. The grim reality tells us that since the implementation of the most stringent "New Environmental Protection Law" in history, the law enforcement has maintained a high-pressure situation. It's time for zero tolerance for breaking the law. In addition, with the development direction of automobile lightweight, the quality requirements for truck parts are getting higher and higher. [0003] The manufacturing methods of truck balance suspension manufacturers are different. Generally, the structural balance suspension is two components, the support and the forged bent axle to independently bear the force. This kind of structure is easy to cause forging bending due to...

AI Technical Summary

Problems solved by technology

[0003] Truck balance suspension manufacturers have different manufacturing methods. The general structure of the balance suspension is that the support and the forged bent shaft are two parts that independently bear the force. This structure is easy to cause the forged bend due to the separate force under severe road conditions. Shaft fracture, (a), the traditional balance shaft is a bent shaft connected with two supports, which requires large-scale forging equipment to complete, making the cost of forging a balanced bent shaft very high; (b), currently all manufacturers are The casting method is used to produce the support. Due to the casting defects and uneven wall thickness of the casting support, it is easy to cause the support to tear, which will bring various adverse consequences to the car. Under the strict suppression of environmental protection, the cost of the casting support will be reduced stay high
