Abstract

The invention discloses a built-in driving system with a two-gear mechanism, and relates to the technical field of electric vehicle power systems. The built-in driving system with the two-gear mechanism comprises a motor and a speed reducer, and further comprises a controller which is used for controlling the motor to rotate forwards or backwards; the speed reducer comprises a driving shaft, a speed reducing shaft and an output shaft, wherein the driving shaft is used for being connected to the motor, the speed reducing shaft is connected to the driving shaft and the output shaft is connectedto the speed reducing shaft; a high-speed gear speed reducing gear and a high-torque speed reducing gear are arranged on the speed reducing shaft in a rotating mode, and gear shifting teeth are arranged between the high-speed gear speed reducing gear and the high-torque speed reducing gear; the gear shifting teeth are fixed on the speed reducing shaft, a shifting fork is arranged on the gear shifting teeth in a sleeve mode, the shifting fork moves relative to the gear shifting teeth when the shifting fork rotates forwards or backwards along with the gear shifting teeth, and the shifting fork is connected to the high-torque speed reducing gear or the high-speed gear speed reducing gear; and a high-speed gear output gear which is meshed with the high-speed gear speed reducing gear and a high-torque output gear which is meshed with the high-torque speed reducing gear are arranged on the output shaft. According to the scheme, the requirement for the speed of the electric vehicle can be met, and the requirement for the torque of the electric vehicle can be met.

Description

technical field [0001] The invention relates to a power system of an electric vehicle, in particular to a mid-mounted drive system with a two-speed mechanism. Background technique [0002] At present, electric vehicles are mainly driven by hub motors, and motorcycles are mainly driven by engines. The hub motors and engines are the power drive systems, which are finally converted into mechanical energy, thereby driving the wheels to rotate and driving the vehicle forward. [0003] When an electric vehicle needs to climb a slope, it needs to output a large torque. When the high torque output is satisfied, it cannot meet the speed requirement of the electric vehicle. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mid-mounted drive system with a two-speed mechanism, which can not only meet the speed requirements of electric vehicles, but also meet the torque requireme...
