Problems solved by technology

However, under such transmission conditions, the speed range of the motor is proportional to the vehicle speed. At low speeds, the starting current is large, the acceleration time is long, and the overall efficiency is low; Accelerated working conditions, less overall mileage

Abstract

An electromobile dual-power continuously-invariable transmission comprises a box, a planet gear set, a planet gear ring, an output shaft rotatably arranged on the box, a first input shaft and a secondinput shaft. Planet gears are meshed with the planet gear ring, a sun gear is fixed on the output shaft, the sun gear and the output shaft can be arranged to be of an integral structure, the sun gearis meshed with each planet gear, a transmission frame gear is coincident with a central line of the sun gear, a first gear is connected on the first output shaft in a sleeved manner and meshed with the transmission frame gear, a second gear is connected on the second output shaft in a sleeved manner and meshed with the planet gear ring, and an anti-reversing gear meshed with the planet gear ringis arranged inside the box. The continuously-invariable transmission realizes dual-power input and rotating-speed stepless output, service life is prolonged, electromobile driving mileage is prolongedgreatly, and the transmission can be widely applied in various high-speed electromobiles and electric logistics vehicles.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a dual-power continuously variable transmission for electric vehicles. Background technique [0002] The driving mode of current electric vehicles is mostly direct drive, and there are not many special gearboxes for electric vehicles on the market. Most of the only gearboxes are manual gearboxes remanufactured from automobile gearboxes. Automatic transmissions are rarely used because of cost. Due to the low noise of the motor of the electric vehicle, the manual gearbox has high technical requirements for the driver, and at the same time, there are misoperations when shifting gears on slopes, and the burning of friction plates occurs from time to time; [0003] However, in the automatic transmissions for electric vehicles on the market, the shift mechanism uses a micro-motor to complete the action of the shift fork, which causes relatively large damage to t...
