Embodiment 1

[0025] The invention discloses a vehicle composite material control arm which integrates metal inserts, thermoplastic carbon fiber composite materials and plastic materials. panel. The shape of control arm body 1, structure are identical with existing control arm body, comprise three ends, as figure 1 As shown, metal inserts are respectively embedded in the two ends, that is, the first bush 2 and the second bush 3. Specifically, the first bush 2 is placed horizontally, and the second bush 3 is vertically placed. Placed vertically, the third end of the control arm body 1 has three connection holes 11 for riveting or screwing the ball head 4, that is, the ball head 4 is installed after the control arm body 1 is formed. A plastic part 5 is also injection-molded on the control arm body 1 .

[0026] Specifically, the plastic part 5 includes an outer frame 51, a reinforcing mesh 52 and a bush connector 53; wherein, the outer frame 51 is located on the edge of the control arm body ...

Abstract

The invention discloses a vehicle composite material control arm and a forming process thereof, the vehicle composite material control arm comprises a control arm body, a first lining and a second lining are respectively embedded in two end parts of the control arm body, the control arm body is a thermoplastic carbon fiber composite material molded plate, and the control arm body is also provided with an injection-molded plastic part; the forming process comprises the following steps: (1) preparing a thermoplastic carbon fiber composite board; (2) cutting and putting into a mold; and (3) performing mold pressing and injection molding. According to the composite material control arm for the vehicle and the forming process thereof, a thermoplastic carbon fiber one-way belt and thermoplastic plastic particles are used as raw materials, the thermoplastic composite material control arm is rapidly prepared by adopting a forming mode of combining mold pressing and injection molding, the forming period is effectively shortened, and the production efficiency is improved; and the plastic parts are synchronously formed on the control arm body by adding the thermoplastic injection molding process, so that the structural strength and the deformation resistance of the control arm are improved, and the service life of the control arm is prolonged.

Description

technical field [0001] The invention relates to the field of vehicle accessories, in particular to a composite material control arm for vehicles and a forming method thereof. Background technique [0002] The automobile control arm is the guiding and force-transmitting element of the automobile suspension system. Its purpose is to elastically connect the wheel and the body through a ball joint or a bushing, and transmit various forces acting on the wheel to the body. At the same time, ensure that the wheels move according to a certain trajectory. In order to meet the above functions, the automotive control arm needs to have sufficient rigidity, strength and service life. [0003] Traditional automotive control arms are mostly made of metal, which is heavy and consumes a lot of energy, which does not meet the requirements of energy saving and emission reduction. With the development of carbon fiber composite materials and their application in the automotive field, the indus...
