Abstract

The invention relates to the technical field of automobile tubular shafts and joints, discloses a carbon fiber composite transmission shaft joint structure, and solves the problems that the service life of a transmission shaft body is short and the transmission shaft body is inconvenient to replace due to poor pressure resistance of the transmission shaft body. The carbon fiber composite transmission shaft joint structure comprises a transmission shaft body, wherein transmission shaft connecting bodies are symmetrically arranged at the two ends of the transmission shaft body; universal joint connectors are connected to the two ends of each transmission shaft connecting body; first cavity grooves are formed in the transmission shaft body; reinforcing assemblies are arranged in the first cavity grooves at equal intervals; second cavity grooves are formed in the universal joint connectors; and first reinforcing rods are arranged in the second cavity grooves. By arranging the first cavitygrooves, the weight of the transmission shaft body is effectively reduced, and convenience is brought to use of the transmission shaft body; and through the design of the reinforcing assemblies and reinforcing toothed plates, the strength of the transmission shaft body is effectively improved, and then the compression resistance of the transmission shaft body is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile pipe shafts and joints, in particular to a carbon fiber composite transmission shaft pipe joint structure. Background technique [0002] The transmission shaft is an essential component in the power transmission system of the front-engine rear-drive vehicle. During the power transmission process, the transmission shaft must bear the required torsional load. Bending load, therefore, the stiffness, strength and fatigue life of the transmission shaft have an important impact on the performance of the vehicle. [0003] At present, the transmission shaft of automobiles is welded by steel pipes with a certain diameter and wall thickness and universal joints with equal diameters at both ends. Due to the high density of steel, the mass of the transmission shaft is large, and the pressure resistance of the transmission shaft is poor. At the same time, fuel consumption and emissions The increase will al...
