Problems solved by technology
Therefore, at present, the measurement of the transmission clearance of the differential and the main reduction gear can only be carried out before the assembly of the final reduction gear, which affects the assembly efficiency of the final reduction gear, and cannot accurately measure the transmission clearance of the differential and the main reduction gear in the assembled state. Transmission clearance of reduction gear

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with embodiment.
[0020] During specific implementation: if figure 1 and figure 2 As shown, a transmission gap measuring device includes a base 17, a tested main reducer 5 and a drive motor 1 installed on the base 17; An angular displacement sensor 4 is coaxially connected with the output shaft of the drive motor 1; a second angular displacement sensor 6 is installed on the second semi-axis of the measured final drive 5; a second angular displacement sensor 6 is installed on the base 17 There is a locking device 8 capable of blocking the second half-shaft, and the second half-shaft is releasably connected to the locking device 8; Triangular displacement sensor 9.
[0021] With the above structure, when measuring, the second half shaft can be disengaged from the locking device first, and then the drive motor can be used to drive the first half shaft to rotate in the opposite direction. T...

The invention discloses a transmission clearance measurement method comprises the steps of: locking a second half shaft of a measured main gear box, and rotating a first half shaft until an input shaft of the measured main gear box rotates; unlock the second half shaft, and reversely rotating the first half shaft until the second half shaft is driven to rotate; determining the transmission clearance of a differential gear according to a rotational angle difference between the first half shaft and the second half shaft; locking the second half shaft of the measured main gear box again, and rotating the first half shaft until the input shaft of the measured main gear box rotates; under the locking state of the second half shaft, reversely rotating the first half shaft until the input shaft of the measured main gear box rotates; determining the overall transmission clearance of the main gear box according to the rotational angle difference between the first half shaft and the input shaft;and performing subtraction on the overall transmission clearance of the main gear box and the transmission clearance of the differential gear to obtain the transmission clearance of a main reductiongear. According to the transmission clearance measurement method, the invention has the advantages that the transmission clearances of the differential gear and the main reduction gear can be measuredseparately for the assembled main gear box.
Description
technical field [0001] The invention relates to the technical field of automobile testing, in particular to a transmission gap measurement method. Background technique [0002] As the power transmission device between the automobile engine and the driving wheel, the automobile power transmission system includes the main components such as the gearbox, the transmission shaft and the main differential. Since its components include many gears or splines and universal joint structures, There must be a certain backlash if there are gears, and the structure of the transmission shaft is often relatively long, so there will be a certain transmission backlash after the force is applied. If the backlash of the gears is too large, it will cause impact between the teeth, generate meshing noise and affect Transmission stability, and excessive transmission clearance will cause automobile NVH problems. The transmission clearance of the universal joint or spline will affect the performance...
