Problems solved by technology

[0004] The purpose of the present invention is to overcome and solve the disadvantages of the limited high-efficiency working range of the existing electric vehicle motor, the existing two-speed automatic transmission or the interruption of shifting power, the phenomenon of slipping when going uphill, or the clutch is easy to wear and has poor reliability. The problem is to provide a two-speed automatic transmission with a brake ring gear so that the electric motor can work in a high-efficiency working area

Abstract

The invention provides an automatic two-gear transmission with a brake gear ring and relates to an automobile power transmission device. The automatic two-gear transmission comprises a planet carrierconnecting shaft 1, a planet carrier 2, a planet gear 3, a sun gear 4, the gear ring 5, a sun gear connecting shaft 6, a one-way clutch 7, a brake 8, a reduction gear A9, a reduction gear B10, a reduction gear connecting shaft 11 and a clutch 12. By the adoption of the automatic two-gear transmission, continuous power during gear shifting can be achieved, the phenomenon of sliding on a slop duringthe uphill can be prevented, the wear to the clutch is reduced, and the reliability is improved.

Description

Technical field [0001] The invention relates to an electric vehicle power transmission device, in particular to a two-speed automatic transmission with a brake ring gear. Background technique [0002] Due to the different driving conditions of electric vehicles, the speed difference is relatively large. If there is no transmission, the motor needs to be able to output a wide range of speed. The performance requirements of the motor are very high, and the efficient working range of the motor is limited. If the motor works in a low power consumption area, Higher energy consumption reduces the endurance of electric vehicles. Although the performance of the electric motor is better than that of the engine, there is no need to configure a multi-speed transmission like the engine, but at least a two-speed transmission that can achieve high and low gears is required. The operation of ordinary manual transmission is troublesome. The power and economy depend on the driving experience of ...
