[0003] A light commercial vehicle with a 9AT automatic gearbox is required to automatically switch to P gear when the vehicle is powered off in the electrical design. However, when checking and adjusting the wheel hub and toe of the vehicle, the gear needs to be switched to N gear. In order to detect, the operator usually needs to stretch his arm at the bottom of the vehicle or in the front cabin, lie on the engine compartment parts, and use the shift arm to complete the operation from P gear to N gear, and needs to be maintained in N gear until the gear is automatically restored to P gear after the detection is completed. Due to the small operation space, the gear shifting operation is extremely inconvenient, time-consuming and affects the efficiency. When the product batch is not large, the production rhythm can be balanced by reasonable production arrangement.

[0004] With the increase of the product quantity of the 9AT automatic gearbox, the long-time gear shifting operation and maintaining process makes the man-machine engineering problem prominent, and gradually becomes the main bottleneck affecting the production line rhythm.

[0005] If the gear shifting method of operating at the bottom of the vehicle or in the front cabin is continued, it is difficult to meet the requirements of balanced production rhythm, and the man-machine engineering condition is poor, therefore, the time control of gear shifting operation and maintaining N gear needs to be reconsidered, and the man-machine environment needs to be improved.

[0008] Further, the device body comprises a positioning block and a fixed positioning block clamp for positioning and fixing the device and the transmission housing, a shaft sleeve for rotating the driving rod, and a support arm rotatably connected to the gear shifting push rod at one end, and the positioning block, the fixed positioning block clamp and the shaft sleeve are integrally welded into an integral component; the positioning block and the fixed positioning block clamp are fixed with the transmission housing.

[0009] Further, the driving rod comprises a handle, a rotating shaft and a crank, and the handle, the rotating shaft and the crank are integrally welded into an integral component, and the shaft sleeve is rotatably sleeved with the rotating shaft; the free end of the crank is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is provided with a baffle abutting against the gear shifting push rod.

[0010] The device body has a first working state that the handle is rotated, the rotating shaft is rotated around the shaft sleeve, the rotating shaft drives the crank to rotate, the crank drives the connecting rod to move, the connecting rod drives the gear shifting push rod to rotate around the support arm, and the gear shifting push rod drives the gear shifting arm of the automatic transmission to shift gears, so as to realize the quick switching from P gear to N gear.

[0011] Further, the handle, the crank and the connecting rod are rotated and located in the same vertical plane, the connecting rod pushes the gear shifting push rod and is pressed tightly, the gear shifting arm of the automatic transmission is acted on by the return spring, the mechanism is self-locked, the automatic transmission is maintained in the N gear state, and normal inspection and adjustment work is ensured.

[0012] Further, the slender shaft sleeve and the rotating shaft have no interference with the cabin, the handle is arranged outside the cabin space, so that the operator does not need to enter the cabin and only needs to rotate the handle outside to complete the gear shifting operation.

[0013] The device can be placed above the gear shifting arm of the automatic transmission and positioned and fixed with the transmission housing through the narrow space in the cabin, the handle outside the narrow space is rotated, and the gear shifting push rod inside the narrow space is driven to shift gears. The problem that the arm is prostrated on the cabin components in the vehicle bottom or the front cabin of the upper part of the vehicle to manually maintain the gear state for the automobile inspection and adjustment is solved. Experimental results show that the automatic transmission is switched from P gear to N gear and is stably maintained in the N gear state, the automobile inspection and adjustment work is smoothly ensured, the production requirements of the detection line are met, and the problems of the "bottleneck" process and the poor man-machine environment of the production line are completely solved.
