Carbon fiber winding paving variable cross-section adhesive transmission shaft and combined type mould thereof

Abstract

The invention relates to a carbon fiber winding paving variable cross-section adhesive transmission shaft and a combined type mould thereof. The carbon fiber transmission shaft comprises a carbon fiber tube 1, an integrated joint 2 and the combined type mould. The two ends of the carbon fiber tube 1 are bonded on the integrated joint 2, a three-ball pin column at the other end of the integrated joint 2 is matched with a needle bearing 3 and a ball ring 4 to form constant-speed universal connection, and the needle bearing is limited by a clamp spring. A clamp 5 is in a cylindrical shape, and the mold and machining equipment are connected by the clamp 5. The combined type mould comprises a mould body 6 with the two ends being hexagon-like cross sections (including a transition section) and amould body 7 with the middle being circular cross section, and the combined type mould is positioned and matched by a groove and a boss on the mould and then connected with the cylindrical clamp 5. Acenter hole of a square block 8 is used for assisting demoulding. According to the carbon fiber winding paving variable cross-section adhesive transmission shaft and the combined type mould thereof,the design is reasonable, assembly and disassembly of the mould are convenient, the paving scheme is flexible, the problem that demoulding is difficult is solved, the material performance is sufficiently utilized, the transmission shaft and the combined type mould can adapt to different machining equipment and working conditions, the feasibility and operability are high, the weight is lowered by about 53% compared with steel, the inertia is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of design, manufacture and processing of carbon fiber transmission shafts for vehicles, in particular to carbon fiber composite layup scheme design and winding process, different transmission working conditions, mold design, joint design, lightweight design, bonding and demoulding processes. Background technique [0002] The use of carbon fiber composite materials instead of traditional steel to manufacture the chassis parts and body of the car can reduce the weight of the car and use it for the transmission shaft to reduce the moment of inertia, thereby reducing gasoline consumption and environmental pollution. The transmission shaft made of carbon fiber composite material is light in weight, has good fatigue resistance and corrosion resistance, and has low noise, good vibration attenuation and good safety, and is especially suitable for large and heavy-duty transmission shafts. Carbon fiber composite trans...
