Problems solved by technology

At the same time, general formula cars generally only have two damping suspensions, and the springs used are mostly single-stiffness springs to resist roll, but they cannot produce damping of different sizes, and the damping effect is poor; Anti-pitching and sudden braking will directly affect the performance of the car, the driver's handling stability and personal safety.

Abstract

The invention discloses a variable-rigidity third damping suspension for a formula car. The variable-rigidity third damping suspension comprises a vehicle body main frame, front independent suspensionassemblies are arranged at the two sides of the front portion of the vehicle body main frame, and a third damping suspension is arranged at the front portion of the vehicle body main frame and comprises connecting blocks hinged to the two sides of the vehicle body main frame respectively. A connecting frame is connected between the two connecting blocks through a connecting rod, and a third spring is arranged between the vehicle body main frame and the connecting frame. A first spring cushion block is arranged on a positioning rod, a first rigidity spring is arranged between a second spring cushion block and the first spring cushion block, a second rigidity spring is arranged between a third spring cushion block and the second spring cushion block, and a third rigidity spring is arrangedbetween a lower spring washer and an upper spring washer. According to the present invention, under the impact action of different degrees, different damping magnitudes can be generated, and a betterdamping effect is achieved; and in addition, a very good inhibition effect is achieved for the acceleration backward bending and sudden braking forward bending.

Description

technical field [0001] The invention relates to the technical field of racing cars, in particular to a third damping suspension with variable stiffness for formula racing cars. Background technique [0002] As a challenging sport, formula racing has different performance requirements for vehicles than ordinary vehicles. The double-wishbone independent suspension plays an important role in formula racing cars. The general suspension system is composed of springs and shock absorbers. The shock absorbers are not used to support the weight of the car body, but to restrain the spring from absorbing vibration. Oscillation during rear rebound and absorption of road impact energy. The spring plays the role of easing the impact, changing "one impact with high energy" into "multiple impacts with small energy", and the shock absorber is to gradually reduce "multiple impacts with small energy". At the same time, general formula cars generally only have two damping suspensions, and the...
