Abstract

The invention provides a two-gear speed changing box and electric automobiles and relates to the technical field of automobiles. The two-gear speed changing box comprises a shell, an input device, a gear shifting device and a shifting fork device, wherein the input device comprises a power input shaft pivotally connected with the shell, a driving large gear and a driving small gear fixedly connected with the power input shaft; the gear shifting device comprises a middle shaft, a synchronizer component connected with the middle shaft, and a driven large gear and a driven small gear pivotally connected with the middle shaft; the driving large gear is meshed with the driven small gear; the driving small gear is meshed with the driven large gear; the synchronizer component is capable of connecting the driven large gear or the driven small gear with the middle shaft; the shifting fork device comprises a shifting fork for driving the synchronizer component to move, a driving part for drivingthe shifting fork to move and an angle sensor electrically connected with the driving part and used for adjusting the rotating angle of the driving part. The two-gear speed changing box has the characteristics of high practicability and high power.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a two-speed gearbox and an electric vehicle. Background technique [0002] Electric vehicle is a new type of vehicle driven by vehicle-mounted power battery. Because electric vehicle has the characteristics of energy saving, environmental protection and light weight, and the use cost is low, it has become more and more popular among manufacturers and car owners in recent years. Pay attention to. Electric vehicles generally include power supply, motor, gearbox, walking assembly and control system. Due to the operating characteristics of the motor, the gearbox of an electric vehicle generally does not use gear shifting. It directly controls the speed of the motor to control the speed of the vehicle, and then achieves electric power. The car is running normally, among which, the front gearbox can improve the overall balance and operability of the car. [0003] Although t...
