Embodiment Construction
[0029] In some embodiments, the respective two outer surfaces of the two wishbone skeletons refer to two surfaces parallel to the V-shaped cross section. The inner side of the two wishbone frames and the outer side opposite to the inner side refer to the V-shaped inner side and the V-shaped outer surface opposite to the inner side.
[0030] like Figure 1~4 Shown are respectively a perspective view, a front view, a side view and a top view of a yoke in a preferred embodiment of the present invention. The wishbone includes two wishbone frames 5 , a vehicle frame connecting hole 2 and a steering knuckle connecting hole 3 . Two wishbone skeletons 5 form a V-shaped structure. The vehicle frame connection holes 2 are located on the tops of the end faces of the V-shaped openings of the two wishbone frames 5 extending outward. There are two vehicle frame connecting holes 2. The frame connecting hole 2 is used to connect the wishbone and the frame through the rod end bearing. Aft...

The invention discloses a fork arm for a vehicle and a processing method thereof. The processing method comprises the following steps of: milling the surface of a first plate to obtain two fork arm skeletons forming a V-shaped structure; drilling the top of outwards-extending end faces of an opening of the V-shaped structure formed by the two fork arm skeletons to obtain two rack connecting holes; drilling the top of end faces of a connecting end of a connecting part of the V-shaped structure formed by the two fork arm skeletons to obtain two steering node connecting holes; tapping the steering node connecting holes and the rack connecting holes to obtain steering node connecting holes with internal threads and rack connecting holes with internal threads, and finishing processing of the fork arm, wherein the rack connecting holes are used for connecting fork arm and a rack, and the steering node connecting holes are used for connecting the fork arm and a steering node. The form arm is formed by integrated numerical control milling, a processing technology is simple, workload of previous preparation is low, unnecessary risk caused by a sand hole in a material can be controlled on the premise of ensuring the intensity of all parts, and the fork arm is excellent in material integration and high in intensity.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a yoke for vehicles and a processing method thereof. Background technique [0002] The wishbone is one of the main parts in the car suspension system. The suspension system composed of wishbones, springs and shock absorbers is the only bridge connecting the wheels and the body. All gravity and other external forces on the body are borne by the suspension system and finally transmitted to the wheels and the ground. On the contrary, all the resistance and other forces that the car receives on the ground are also transmitted to the body through the suspension system. It can be seen that all the interaction forces between the body and the ground are realized through the wishbone, which is the main load-bearing structure of the car. Usually, the suspension system of a vehicle adopts a double-wishbone structure. Through the interaction between the upper and lower wishbone, most of the force...
