Problems solved by technology

Among them, the production of the fixed-length winding process is discontinuous, and the production efficiency is not high; while the pultrusion process is very suitable for the production of fiber-reinforced composite materials in the 0° direction, but it is difficult to achieve accurate laying of non-0° fibers. Conducive to the manufacture of composite automotive drive shafts with high requirements for lateral performance and other properties

Abstract

The invention belongs to the field of a composite material, and relates to a composite-material automobile transmission shaft formed by pulling, squeezing and winding and a preparation method thereof. The composite-material automobile transmission shaft comprises a shaft pipe (1), metal connection pieces (2) and a glue layer (3), wherein the shaft pipe (1) sequentially comprises a pipe body (4), a lug boss (5) and a fabric reinforcing layer (6) from outside to inside; and the both ends of the shaft pipe (1) are connected with the metal connection pieces (2) through the glue layer (3) and the lug boss (5) in a spline connection and glued connection combined manner. The reasonable composite-material automobile transmission shaft is implemented according to a pulling, squeezing and winding process, the lug boss made of a composite material formed by pulling and squeezing is arranged on the inner side of the automobile transmission shaft along the axial direction of the entire shaft pipe, and at the connection part, the shaft pipe and each metal connection piece are connected with each other in the spline connection and glued connection combined manner, so that the connection strength is enhanced, and the automobile transmission shaft can be reliable for a long time.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a pultrusion winding composite automobile drive shaft and a preparation method thereof. Background technique [0002] The car drive shaft is the transmission that connects the transmission and drive axle. Generally, when the length of the traditional metal transmission shaft exceeds 1 meter, in order to avoid the resonance phenomenon caused by the low critical speed, it is often necessary to divide the transmission shaft into two sections. The use of composite materials to manufacture such transmission shafts can simplify the two-section transmission shaft into a single piece, which not only reduces the shaft weight, but also subtracts the intermediate support and corresponding connection and sealing elements, effectively reducing the total weight of the transmission system. [0003] At present, composite automobile transmission shafts are mainly fiber-reinforced resin-based com...
