Double-power transmission

Abstract

The invention discloses a double-power transmission. The double-power transmission comprises a first power input part, a second power input assembly, a power input shaft and a power output shaft which is in gear transmission fit with the power input shaft through a gear transmission chain. The first power input part is arranged on the power input shaft in a transmission mode and inputs first power in a mode that power can be transcended. The second power input assembly at least comprises a second power input gear I as a driving gear in the gear transmission chain. The second power input gear I is in transmission fit with the power input shaft and inputs second power. The condition that a motor in hybrid double power needs a reduction gear and a transition gear is avoided, the compact structure is ensured, the installation occupied space is small, the material cost of parts is reduced, self weight is reduced, and the double-power transmission is especially suitable for a motor tricycle. Meanwhile, the second power in a double-power output assembly is input by a driven gear of the transmission, large outwards output torque can be ensured, the motor power input efficiency is high, the power output performance is good, and the adaptation is good.

Description

technical field [0001] The invention relates to a transmission, in particular to a dual power transmission. Background technique [0002] Motor vehicles are divided into electric vehicles (two-wheel, three-wheel and electric vehicles) and vehicles powered by fuel engines. Electric vehicles are powered by on-board power batteries to drive electric vehicles. Because electric vehicles are energy-saving, environmentally friendly and portable, And the cost of use is low, and more and more people pay attention to it. However, electric power has poor sustaining ability, limited driving speed, and poor climbing ability. To solve this problem, more small cars are driven by dual-power switching. Before reaching a certain speed, they are only driven by the electric motor. The engine works to achieve the purpose of good working condition, good power and low emission. In the prior art, the structure of the hybrid dual-power reducer is relatively complicated, especially the installation...

Problems solved by technology

However, electric power has poor sustaining ability, limited driving speed, and poor climbing ability. To solve this problem, more small cars are driven by dual-power switching. Before reaching a certain speed, they are only driven by the electric motor. The engine works to achieve the purpose of good working condition, good power and low emission

In the prior art, the structure of the hybrid dual-power reducer is relatively complicated, especially the installation of the drive motor usually needs to cooperate with the input of the reduction gear and the transition gear, so that the installation takes up too much space and the overall weight is heavy, which is not suitable for driving on road conditions. Poor rural and mountainous roads are also not suitable for small motor vehicles that need to be lightweight, and the stability of the motor power input is poor, which is easy to cause other losses in the transmission process of power, and there are many transmission parts, which is not conducive to cost control, can not be well adapted to the compact and economical requirements of small motor vehicles
