Elastic mechanism used for suspension

Abstract

The invention discloses an elastic mechanism used for a suspension. The elastic mechanism is characterized in that peripheral-distribution power springs and a gear drive mechanism are used, the torqueof the power springs is increased to meet the demand of vehicle suspension elastic elements for torque, the size and the weight of the suspension elastic elements are reduced, and the elastic mechanism is structurally composed of the power springs 1, an installing base plate 4, a planetary gear 10, an inner tooth ring 12 and a motor 20, is suitable for suspensions of passenger vehicles, railway vehicles and engineering vehicles, and is particularly suitable for suspensions of electric automobiles.

Description

technical field [0001] The invention relates to an elastic mechanism for suspension, which has the function of amplifying the torque of a clockwork spring to meet the torque requirements required by the elastic components of the vehicle suspension, and is suitable for the suspension of passenger cars, rail vehicles and engineering vehicles, especially Suitable for suspension use of electric vehicles. Background technique [0002] At present, the car mainly uses coil springs and torsion bar springs as the elastic components of the suspension. The coil springs are large in size and low in energy density, while the torsion bar springs increase the energy density and can be arranged horizontally and vertically along the frame. Due to their small size, they are more affected. However, the length of the torsion bar is relatively large, which still affects the structure of the frame and the space of the compartment. Especially when the rear axle of a car is independently suspended,...

Problems solved by technology

[0002] At present, the car mainly uses coil springs and torsion bar springs as the elastic components of the suspension. The coil springs are large in size and low in energy density, while the torsion bar springs increase the energy density and can be arranged horizontally and vertically along the frame. Due to their small size, they are more affected. However, the length of the torsion bar is relatively large, which still affects the structure of the frame and the space of the compartment. Especially when the rear axle of a car is independently suspended, it often results in a reduction in the space of the rear seats and the trunk space, and the energy of the clockwork spring The density is high, but the torque provided by the single body is small, and the inner hole of the clockwork spring is small, and the inner shaft is difficult to meet the strength requirements of the vehicle suspension. Therefore, a new type of vehicle suspension is designed by combining the gear mechanism and the clockwork spring. The elastic mechanism can meet the requirements of the suspension elastic elements of passenger cars and rail vehicles, and has the advantages of compact structure, small volume and easy arrangement
