Hybrid arm and method for its manufacture

Abstract

The mixing arm according to the embodiment of the present invention includes: a first body, which is made of metal material and formed with multiple ends; a second body, which is inserted into the first body by insert injection molding, so that the The inner side of the first body is filled; the ball joint is integrated with the first end of the plurality of ends of the first body. The ball joint includes: a reinforcing material combined with the first end; a bearing member having a space formed therein; and a ball stud consisting of two parts, that is, rotatably inserted into A ball in the space of the bearing member, a link extending above the ball, and a cover sandwiched between the reinforcing material and the bearing member are integrally formed with the second body.

Description

technical field [0001] The invention relates to a hybrid arm (Hybrid Arm) and a manufacturing method thereof. Specifically, it relates to a mixing arm integrally formed with a ball joint and a manufacturing method thereof. Background technique [0002] Generally speaking, the suspension system of a vehicle, as a device that connects the wheels to the vehicle body, consists of a spring that absorbs the impact from the road surface; a shock absorber that adjusts the action of the spring; The control arm or connection mechanism; the stabilizer to prevent the car from fluctuating, etc. [0003] The vehicle suspension is an important device for improving ride quality and running stability, and its main function is to stably support the vehicle body from the wheels and suppress or quickly reduce the vibration provided by the wheels. [0004] This type of suspension is equipped with a lower swing arm, the function of which is to connect the wheel to the vehicle body and provide s...

Problems solved by technology

[0016] However, as mentioned above, the existing ball joints use castings to make metal covers, and the surface can only be used after grinding.

Also, in order to assemble the ball joint, it is necessary to use additional parts, thus increasing the weight of the ball joint

Therefore, the weight of a vehicle that typically uses several to tens of ball joints increases, not only resulting in a decrease in fuel economy of the vehicle, but also the existing ball joints must go through an additional assembly process of press-fitting them to the lower swing arm, This will prolong the manufacturing time and increase the manufacturing cost
