Semi-active suspension damping adjusting device for electric automobile

Abstract

The invention relates to the technical field of vehicle energy saving and emission reduction, in particular to a semi-active suspension damping adjusting device for an electric automobile. The semi-active suspension damping adjusting device for the electric automobile comprises a spiral lead screw mechanism connected with an automobile body; a CVT input shaft is connected under the spiral lead screw mechanism; the spiral lead screw mechanism is used for converting up-and-down vibration of the automobile body into rotation of the CVT input shaft; the semi-active suspension damping adjusting device for the electric automobile further comprises a power generator; the power generator is connected with a CVT output shaft; and the CVT input shaft is connected with the CVT output shaft through a stepless speed change device. According to the semi-active suspension damping adjusting device for the electric automobile, by combining a direct current power generator and the belt type stepless speed change device and adjusting the speed ratio of the belt type stepless speed change device, the damping of a suspension system is adjusted; therefore, the damping can be continuously adjusted to improve automobile running smoothness.

Description

technical field [0001] The invention relates to the technical field of vehicle energy saving and emission reduction, in particular to a semi-active suspension damping adjustment device for an electric vehicle. Background technique [0002] With the continuous increase of the number of automobiles and the improvement of national requirements for energy conservation and environmental protection, automobile energy conservation and emission reduction has become the primary issue facing the development of the automobile industry. Electric vehicles have become a national key development target due to their advantages of zero emissions, but the long charging time and relatively short mileage of vehicles limit their development and application. If the vibration energy of the car body can be recycled during the driving process of the car, it will effectively increase its mileage and improve the economy of the car. [0003] At present, automobile suspension systems often use traditio...
