Upper swing arm being simple in structure

Abstract

The invention discloses an upper swing arm with a simple structure, which comprises a U-shaped upper swing arm body, a mounting shaft hole for installing a ball stud provided at the center of the upper swing arm body, and a mounting shaft hole welded to the upper swing arm body. The first connection shaft hole and the second connection shaft hole at the two ends of the upper swing arm body, the upper swing arm body at both ends of the first connection shaft hole and the second connection shaft hole Anti-collision flanges are all provided, and a plurality of bolt holes are opened on the two vertical arms of the upper swing arm, and the width of the two vertical arms of the upper swing arm is smaller than that of the cross arm of the upper swing arm. width. The upper swing arm with simple structure of the present invention is not only simple in structure and convenient for production and processing, but also reduces the width of the cross arm because the width of the two vertical arms of the upper swing arm is smaller than the width of the cross arm The impact of the concentrated stress at the place on the strength of the product has a greater structural strength.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an upper swing arm with a simple structure. Background technique [0002] The suspension system on the car is installed between the body and the wheels to reduce the vibration transmitted from the wheels to the body during driving and improve the stability and comfort of driving. Suspension swing arm The connecting and guiding parts of the suspension system on the swing arm mainly include the swing arm body and the ball seat and bushing on the swing arm body, which are connected to the frame assembly through the bushing and passed through the ball. The headstock is connected with the steering mechanism. The shape of the swing arm assembly of ordinary cars is relatively simple, and the processing accuracy requirements are low. In order to ensure the stability and durability of the suspension system and meet the requirements of safety and reliability, the strength of the suspension swing...

AI Technical Summary

Problems solved by technology

The shape of the swing arm assembly of ordinary cars is relatively simple, and the processing accuracy requirements are low. In order to ensure the stability and durability of the suspension system and meet the requirements of safety and reliability, the strength of the suspension swing arm should be as high as possible, but the higher The strength needs to be provided by a thicker swing arm body, which means higher cost, which makes the suspension swing arm unable to balance high strength and low cost; while the shape of the swing arm assembly of mid-to-high-end cars is complex, The structure is fine and the weight is light, but it requires high processing precision, making it difficult to manufacture, and it is difficult to guarantee safety and reliability.
