The invention relates to an execution
system for driving an automobile gearbox to shift gears. The execution
system comprises a shell, a direct-current motor is arranged on one side of an inner cavityof the shell, the direct-current motor is in driving connection with a worm through an output shaft, the worm is positioned on the other side of the shell, a
turbine is arranged in the shell througha rotating shaft, the
turbine is positioned above the worm, and the worm meshes with the
turbine; the rotating shaft is provided with a gear, the gear is further embedded in the center of the turbineand synchronously rotates along with the turbine, a rotating output shaft is arranged in the shell, the rotating output shaft is provided with a fan-shaped gear which synchronously rotates, the fan-shaped gear meshes with the gear, a
control circuit board is arranged in the shell, and a sensor is arranged on the front face of the
control circuit board; and the fan-shaped gear is provided with a
magnet, the
magnet is located above the sensor, when the fan-shaped gear rotates, the
magnet is driven to rotate synchronously, and the magnet and the sensor are arranged in a matched mode. The performance of low cost,
miniaturization,
low noise and the like of the execution
system is realized.
