Description
Technical Field
The invention belongs to the technical field of vehicle transmission parts, and particularly relates to a double-gear-shifting motor actuating mechanism for a mechanical automatic gearbox.
Background
With the popularization of electric vehicles, the power combination of simply using a speed reducing mechanism with a fixed speed ratio to match with a motor gradually shows its own disadvantages. By selecting the automatic gearbox to match with the motor, on one hand, the dynamic property of the vehicle at low speed can be further improved while the highest running speed of the vehicle is ensured, so that the purpose of reducing the size of the motor is achieved; on the other hand, the electric motor can be ensured to work in a high-efficiency operation range to the maximum extent by reasonably selecting the speed ratio, so that the aim of reducing the capacity of a power battery is fulfilled, and finally the overall cost of the power system of the electric automobile can be obviously reduced. Therefore, it is necessary to add a multi-speed mechanical automatic transmission to an electric vehicle. For a shift actuator, an electric motor is the best choice for an automatic transmission of an electric vehicle. Different from the use condition of an internal combustion engine vehicle, the electric vehicle has low requirements on the number of gears, and the automatic gearbox with four different speed ratios can completely meet the use requirements of the electric vehicle. The structure that the gear selecting motor matched with the gear shifting motor adopted by the gear shifting actuating mechanism of the mechanical automatic gearbox is too complex, and the cost is additionally increased. In addition, the gear selecting motor and the gear shifting motor can not act simultaneously, and the power interruption time of gear shifting of the mechanical automatic gearbox is prolonged.
Therefore, a gear shifting actuating mechanism serving as a mechanical automatic gearbox for an electric vehicle is urgently needed, and the gear shifting actuating mechanism comprises two sets of same mechanisms which can improve the utilization rate of parts and reduce the cost to the maximum extent, can output two paths of gear shifting force independently and reduces the gear shifting time.

the gear transmission device is connected with one end of a planetary gear reducer through a straight gear, and the other end of the planetary gear reducer is connected with a coaxial gear shifting motor;
the gear shifting driving force of the gear shifting motor in each independent actuating mechanism is independently transmitted to the finger shifting base of the independent actuating mechanism.
And the axes of the two gear shifting rotating shafts in the two independent actuating mechanisms are collinear.
A gear shifting finger is fixedly connected outside the finger shifting base.
The gear shifting finger penetrates through the movable space on the corresponding side in the safety lock of the double-gear shifting motor executing mechanism; the double-gear-shifting motor actuating mechanism safety lock is used for ensuring that only one of two gear shifting fingers can rotate at the same time.
