Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0025] As shown in the figure, a carbon fiber half shaft for a formula racing car with high torque capacity includes a carbon fiber half shaft main body 1 and a half shaft joint 2. The carbon fiber half shaft main body 1 is in the shape of a hollow sleeve, and the half shaft joint 2 is made of metal. The two ends of the carbon fiber half-axis main body 1 are bonded and fixed with oxygen resin structural glue.

[0026] Wherein, the half-shaft joint 2 can be divided into a glue joint section 3 and a spline section 4 of a three-ball joint. The bonding section 3 includes a bonding area 3.1 and several centering bosses 3.2 with the same radius as the inner diameter of the carbon fiber half shaft main body 1. Axiality, the bonding area 3.1 and the centering boss 3.2 are alternately arranged, and the bonding area 3.1 needs to be roughened before ...

Abstract

The invention discloses a formula car carbon fiber half shaft bearing large torque and a preparation method thereof. The carbon fiber half shaft comprises a carbon fiber half shaft body and a half shaft connector. The carbon fiber half shaft body is in a hollow sleeve shape. The half shaft connector is made of metal and comprises a spline section and a glue joint section connected with the carbon fiber half shaft body. The glue joint section comprises a glue joint groove and centering bosses of which the inner diameter is the same as that of the carbon fiber half shaft body. The carbon fiber half shaft is low in weight, less in rotating inertia, good in corrosion resistance, high in fatigue resistance and long in life.

Description

technical field [0001] The invention relates to a carbon fiber half shaft for a formula racing car, in particular to a carbon fiber half shaft for a formula racing car carrying high torque and a preparation method thereof. [0002] technical background [0003] As the shaft for transmitting torque between the differential of the racing car and the driving wheels, the half shaft of the racing car bears a relatively large torque and must work stably under the conditions of great changes in torque and speed. For this reason, the half shaft of the racing car should have sufficient torsional strength, stiffness and fatigue strength to maintain stable and efficient performance during the start and acceleration of the car, and to maintain sufficient reliability and life under high-strength working conditions. At present, the half shafts of formula racing cars mostly use metal half shafts, which have a large moment of inertia, which affects the smoothness of transmission to a certain...
