Abstract

The invention discloses a double-gear-shifting motor executing mechanism for a mechanical automatic transmission in the field of vehicle transmission device components. The double-gear-shifting motorexecuting mechanism comprises two independent executing mechanisms which are rotationally connected through gear shifting rotation shafts in the independent executing mechanisms, and the axes of the two gear shifting rotation shafts are collinear. The outer end faces of the gear shifting rotation shafts are connected with angle sensors. The inner and outer half sides of the gear shifting rotationshafts are in rigidity connection with stirring finger bases and gear transmission devices correspondingly. The gear transmission devices are connected with one ends of planet gear speed reducers through straight gears, the other ends of the planet gear speed reducers are connected with coaxial gear shifting motors, and each stirring finger base is externally fixedly connected with a gear shiftingstirring finger. According to the double-gear-shifting motor executing mechanism, the component utilization rate is improved, and the cost is effectively controlled; and double-motor coordinated control is adopted, the power interruption time in the gear shifting process is further shortened, and the gear shifting quality is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmission components, in particular to a double-shift motor actuator for a mechanical automatic gearbox. Background technique [0002] With the popularization of electric vehicles, the power combination of simply using a fixed speed ratio reduction mechanism to match an electric motor gradually shows its own shortcomings. By selecting an automatic gearbox to match the electric motor, on the one hand, it can further improve the dynamic performance of the vehicle at low speed while ensuring the maximum driving speed of the vehicle, so as to achieve the purpose of reducing the size of the electric motor; on the other hand, by choosing a reasonable speed ratio, it can maximize Ensure that the motor works in the high-efficiency operating range, so as to achieve the purpose of reducing the capacity of the power battery, and ultimately can significantly reduce the overall cost of the electric vehicle ...
