Embodiment

[0071] Embodiment: A thin-plate stamping-welding forming manufacturing method of a clutch spline hub assembly

[0072] In order to describe the present invention better, the structure of the splined hub assembly is explained first. The splined hub assembly to be manufactured in this embodiment is the main force transmission component in the multi-plate wet clutch module. See attached figure 2 and image 3 As shown, the spline hub assembly is a spline groove convex type spline hub assembly, which is composed of spline hub A and piston cylinder block B. Wherein, the spline hub A is cylindrical, and there are more than two spline grooves C uniformly distributed in the circumferential direction and protruding radially on the outer surface thereof. The spline groove C is provided with more than one transparent oil hole D, and the oil hole D can be a round hole or a waist hole. On the inner circle of the spline groove C, and near the end of one side of the spline groove C, a sna...

Abstract

The invention relates to a manufacturing method for stamping and welding forming of a sheet of a clutch spline hub assembly. The manufacturing method is characterized in that the clutch spline hub assembly is structurally regarded as two parts of a spline hub and a piston oil cylinder body, firstly, the spline hub and the piston oil cylinder body are manufactured separately; then the spline hub and the piston oil cylinder body are welded into a semi-finished product of the spline hub assembly; and finally a finished product is obtained through finishing. The manufacturing processes of the spline hub comprise board blanking, spline groove stamping, oil hole stamping, clamp spring groove forming, spline hub winded welding and spline hub cutting and parting in sequence. The manufacturing processes of the piston oil cylinder body comprise board blanking, piston oil cylinder body stamping forming, central via hole stamping, rivet hole stamping and edge cutting in sequence. The manufacturing method has the characteristics that the spline hubs are manufactured through group processing in two-by-two mode by utilizing boards, then cutting is conducted to form two independent spline hub blanks, next one spline hub blank and the piston oil cylinder body are welded and formed, and finishing is conducted to obtain the spline hub assembly product. The manufacturing method has the advantages of high machining efficiency, material saving, easily-controlled size precision and low cost.

Description

technical field [0001] The invention relates to a method for manufacturing important components of a multi-plate wet clutch in the field of power transmission, in particular to a method for manufacturing a clutch spline hub assembly by punching and welding thin plates. Background technique [0002] The clutch is a key module for power transmission coupling and disengagement control. Among friction clutches, multi-plate wet clutches are widely used in power transmission systems in various fields such as vehicles, industrial equipment, mines, and military affairs. In the multi-disc wet clutch module, the spline hub assembly is the main power transmission part, which is structurally composed of spline hub A and piston cylinder B (see figure 2 and image 3 shown), its manufacturing process directly affects clutch performance and cost. Since the spline hub A of the spline hub assembly is a thin-walled part with a spline groove on the outer circle, the shape is relatively speci...
