Abstract

The invention discloses a three-dimensionally-woven composite automotive transmission shaft and a manufacturing method of the three-dimensionally-woven composite automotive transmission shaft. A three-dimensionally-woven composite transmission shaft pipe and a universal joint are designed and the sleeve connection and combination manner of the three-dimensionally-woven composite transmission shaft pipe and the universal joint is designed according to the stress characteristic of the transmission process of the automotive transmission shaft. Three-dimensional multi-axial fabric structure combination is conducted through a hybrid fiber multi-direction weaving manner, the structural performance of the specific portion of the transmission shaft is strengthened, and finally integrated weaving of the three-dimensional prefabricated body structure is achieved. After a related three-dimensional fabric prefabricated body workpiece is manufactured, the specific fiber is selected to be subjected to thickness-direction seam laying secondary strengthening treatment so that the strength and rigidity in the thickness direction can be improved; and finally, a thermosetting resin glue solution serves as a base material, resin impregnation recombination and resin curing are conducted on the three-dimensionally-woven prefabricated body fabric by the adoption of continuous forming with vacuum infusion and quick thermocuring combined, and finally a three-dimensionally-woven composite automotive transmission shaft assembly made of the hybrid fiber fabric is formed.

Description

technical field [0001] The invention relates to the technical field of preparation of automobile transmission shafts, in particular to a composite automobile transmission shaft with a three-dimensional braided fiber fabric structure applied to different vehicle models and a preparation method thereof. Background technique [0002] As an important power transmission component in the automobile transmission system, the transmission shaft is mainly used together with the gearbox and the drive axle to effectively transmit the power generated during the operation of the engine to the wheels so that the car can generate driving force. Research has shown that 17-22% of the engine energy will be consumed due to its own weight during the operation of the transmission system itself, and the currently used metal transmission shaft will reduce the energy utilization efficiency of the engine due to the large body density of the metal itself. greater burden. In addition, during the opera...
