Abstract

The invention provides an automobile transmission torsion testing machine and a testing method thereof. The automobile transmission torsion testing machine has the advantages of large measurement range, convenient use and accurate gear judgment, and comprises a tailstock, a transmission bracket and a speed reducer which are coaxially arranged on a working platform, wherein the lower part of the tailstock is arranged on the working platform in a sliding manner, and the tailstock is connected with an output end of a measured transmission through a second torquemeter; an output end of the transmission bracket is connected with an input end of the measured transmission, and an input end is connected with an output end of the speed reducer through a first torquemeter; power input is provided for the speed reducer by a driving motor, and an output shaft of the speed reducer is provided with an angle encoder; the measuring range of the first torquemeter is smaller than the measuring range of the second torquemeter; and output ends of the first torquemeter, the second torquemeter and the angle encoder are connected to an input end of an upper computer. Through arranging the torquemeters with different measuring ranges at the front and rear ends, the same static torsion testing machine can be compatible with both small-torque transmission and large-torque transmission, and is wide in coverage.

Description

technical field [0001] The invention relates to a torsion testing machine, in particular to an automobile transmission torsion testing machine and a testing method thereof. Background technique [0002] As the torque section of automobile transmission products continues to extend upwards and downwards, traditional torsion test equipment and methods can no longer meet the needs of development. Considering that there are different gears in automobile transmissions, the input and output torques differ greatly, and the test accuracy requirements are high. . The current problems of the torsion testing machine are as follows: a) The testing machine is generally equipped with a torque sensor at the front end, and the rear end is a fixed end or a moving fixture. The torque sensor has a limited range. b) The tail connection of the testing machine is generally fixed or single-slide connection, the coaxiality is poor, and there is an additional bending moment on the tested piece duri...
