Abstract
The utility model discloses an unloaded moment of torsion loss measuring rack device of gearbox, which comprises a base. Be provided with inverter motor on the base, inverter motor's motor shaft is connected with speed sensor through right shaft coupling, the speed sensor left side is connected with the jackshaft through left -wing federation's axial organ, the axle sleeve of jackshaft is connected with the base of arranging in on the base the base left side is provided with and tests the gearbox connecting plate that the gearbox is connected, the jackshaft left end is connected with the input shaft of test gearbox. The utility model has the advantage of simple structure, convenient to use, it is effectual. Speed sensor measures the rotational speed of the input shaft of test gearbox and the damping torque that receives, calculates the no load losses moment of torsion, the gearbox will be tested and height control by temperature change system incasement will be arranged in, through the temperature in the control box, working condition such as the cold machine of simulation gearbox, heat engine.
Description
Technical field
The utility model relates to automotive field, especially relates to the bench frame apparatus that the unloaded loss of machine of torque of a kind of wheel box is measured.
Background technology
In diesel vehicle clutch coupling matching process, clutch coupling parameter choose is improper often can cause variator idling abnormal sound.Find when studying this problem, the damping torque that when variator is unloaded, input shaft is subject to is most important to choosing of clutch coupling idling level parameter, because the damping torque that input shaft is subject to mainly comes from the viscosity resistance of wheel box fluid to gear, and at different rotating speeds and temperature (showing as cold car and Re Che) viscosity coefficient of fluid great changes have taken place, the damping torque that input shaft is subject to changes thereupon changing.Want Proper Match clutch coupling parameter, make it not cause idling abnormal sound when Re Che or cold car, the damping torque that must be subject to the transmission input shaft under different rotating speeds and different temperatures is measured.At present, domestic automobile designer is when studying idling abnormal sound, usually the damping torque be subject to transmission input shaft carries out static measurement under room temperature, namely the staring torque of input shaft is measured, in this, as the foundation of clutch coupling parameter designing, although this method is simple, but as clutch coupling parameter designing according to having little significance, reason one is the moment that transmission input shaft staring torque is subject to when can not represent idling, and two is the differences not considering the viscosity coefficient of wheel box fluid under cold car, hot turner condition.
Summary of the invention
The utility model object is the bench frame apparatus providing a kind of unloaded loss of machine of torque of wheel box accurately can measuring the various parameter of wheel box to measure.
For achieving the above object, the utility model can take following technical proposals:
The bench frame apparatus that the unloaded loss of machine of torque of wheel box described in the utility model is measured, comprises pedestal; Described pedestal is provided with variable-frequency motor, the motor shaft of described variable-frequency motor is connected with speed probe by right shaft coupling, described speed probe passes on left Left-wing Federation's axial organ and is connected with intermediate shaft, the axle sleeve of described intermediate shaft is connected with the base be placed on pedestal, be provided with and the wheel box web joint tested wheel box and be connected in described chassis left side, described intermediate shaft left end is connected with the input shaft of test wheel box.
Described test wheel box is placed in high/low temperature control box.
The utility model advantage is that structure is simple, easy to use, effective.Speed probe measures the rotating speed of the input shaft of test wheel box and suffered damping torque, calculates no-load loss moment of torsion; Test wheel box is placed in high/low temperature control box, by the temperature in control box, the working conditions such as simulation wheel box cold, heat engine.
