FSC (Formula Student China) formula car carbon fiber suspension and adhesion technology thereof

Abstract

The invention discloses a carbon fiber suspension for an FSC formula racing car and its bonding process. It includes a column for connecting tires. The inner side of the column is connected to the vehicle frame through a guide mechanism. The guide mechanism includes an upper cross arm, a lower cross arm, and a push rod. , rocker arm and stabilizer bar connecting rods and other rods; the above rods are all composed of carbon fiber tubes and metal connectors at their ends; the bonding process includes: grinding and cleaning the bonding surface of carbon fiber tubes and metal joints; Apply to the bonding surface of one end of the carbon fiber tube, then insert the metal joint, and put the bonding end down, let it rest until the glue solidifies; then bond the metal joint at the other end. The invention greatly reduces the unsprung mass of the racing car, improves the acceleration and fuel economy of the racing car, reduces operating costs and carbon dioxide emissions; improves the stiffness and safety of the suspension system; reduces repair time and cost, and improves The handling stability of the car.

Description

technical field [0001] The invention relates to the technical field of suspensions for Formula Student racing cars, in particular to a carbon fiber suspension for FSC formula racing cars and a bonding process thereof. Background technique [0002] The FSC (Formula Student China) competition stipulates that all wheels of the racing car must be equipped with a fully functional suspension with a shock absorber. With a rider on, the tires have a run-out travel of at least 50.8mm2 inches, of which 25.4mm1 inches up and 25.4mm1 inches down. During the technical inspection, all mounting points of the suspension must be presented to the judges, either directly visible or by removing covers. [0003] Nowadays, among the participating teams in the FSC Formula Car Competition, the suspension structure is mainly steel pipe suspension, and very few teams use half carbon fiber half steel pipe suspension. The steel pipe suspension is welded by steel pipes and steel hinges. The suspension...

AI Technical Summary

Problems solved by technology

The steel pipe suspension is welded by steel pipes and steel hinges. The suspension system is too heavy and the response speed is slow, which has a great impact on the fuel economy and power of the car; metal materials are prone to rust and fatigue during long-term use , the safety of the racing car is not high; the maintainability of the steel pipe suspension is poor, once the suspension rod is damaged, it can only be repaired by replacing parts or welding

[0004] The carbon fiber tube has the characteristics of shock absorption and energy absorption, light weight, corrosion resistance, high modulus, low density, and small linear expansion coefficient. It is used in Formula 1 racing cars, but Formula 1 racing cars use integrated carbon fiber rods. That is, the overall demoulding of the carbon fiber cross arm is not only high in manufacturing cost, difficult in the manufacturing process, but also inconvenient in maintenance.
