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 differential-type single-clutch two-speed transmission so that the electric motor can work in a high-efficiency working area

Abstract

The invention discloses a differential mechanism type single-clutch two-gear transmission, and relates to an automobile power transmission device. The single-clutch two-gear transmission comprises a power input part, a power output part, a speed change part and a transmission shell; the power input part is connected with external power; the power output part is connected with a drive axle to drivewheels to rotate; and the speed change part is composed of a differential mechanism, a clutch and at least two one-way clutches. According to the transmission, gear shifting can be carried out without power interrupted, the problems of gear shifting impact and the like caused by power interruption can be solved, the clutch abrasion can be reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to an automobile power transmission device, in particular to a differential type single-clutch two-speed transmission. 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 speed range. The performance requirements of the motor are very high, and the high-efficiency working range of the motor is limited. If the motor works in a low power consumption area, Large energy consumption reduces the battery life 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-gear transmission like the engine, but at least a second-speed automatic transmission that can realize high and low gear work is also required. Existing two-speed transmissions either have power interruption when shifting gears, or need two...
