Process for producing suspension member for vehicle

摘要

A process for producing a suspension member for a vehicle, which member comprises a first mounting portion relatively swingably connected to either one of a vehicle body and an axle, through a connecting member, an a second mounting portion integrally connected to the first mounting portion and connected to the other of the vehicle body and the axle. The first mounting portion is provided at an outer surface thereof with a pair of parallel cam guides of readjusting the relative mounting position between the first mounting portion and a connection member by cooperation with eccentric cams connected to the connecting member. The process comprises steps of forming a base material for the suspension member by an extrusion, and cutting the base material along planes spaced at an equal distance form onto another in an extruding direction to provide a plurality of the suspension members. The extruding direction is set along the cam guides such that the cam guides of each of the suspension members are formed by the extrusion. Thus, the cam guides for adjusting the alignment can be easily formed at given locations on the suspension member with good accuracy.
