Abstract
A fatigue test bench for a passenger car gearbox is provided with a high-speed driving motor, a bearing block, a gear case, a left loading motor and a right loading motor. The high-speed driving motor is connected with the bearing block through a high-speed transmission shaft, a mounting position of the gearbox to be tested is arranged on one side of the bearing block, a first low-speed transmission shaft connected with right output of the gearbox to be tested is connected with the right loading motor, and a second low-speed transmission shaft connected with left output of the gearbox to be tested is connected with the left loading motor through the gear case and a third low-speed transmission shaft. The loading motor on one side of the high-speed driving motor can be staggered from the high-speed driving motor, and the fatigue test bench is simple in structure, high in reliability and high in rotation speed and torque control precision.
Description
Technical field
The utility model relates to a kind of passenger-car gear box fatigue test board.
Background technology
At present on the passenger-car gear box fatigue test board, because the centre distance of wheel box horizontal direction is much smaller than half of high-speed driving motor external diameter, for the loading motor of high-speed driving motor one side and the position of high-speed driving motor are staggered, the general mode that adopts the high-speed driving motor to link to each other with high-speed belt links to each other with an axle of wheel box, because belt tends to produce speed discrepancy in operational process, and the efficient of belt is also lower, therefore the mode that adopts the high-speed driving motor to be connected with high-speed belt often causes the testing table rotating speed, the moment of torsion control accuracy is low, and the high-speed belt reliability is also relatively poor.
Summary of the invention
Efficient is low when linking to each other with high-speed belt in order to overcome prior art high speed drive motor, reliability is relatively poor and testing table rotating speed, the poor deficiency of moment of torsion control accuracy, the utility model provides a kind of passenger-car gear box fatigue test board, it not only can stagger loading motor and the high-speed driving motor position of high-speed driving motor one side, and simple in structure, reliability is high, testing table rotating speed, moment of torsion control accuracy are high.
The technical scheme that its technical matters that solves the utility model adopts is: testing table is provided with high-speed driving motor, bearing seat, gear case, left side loading motor, right side loading motor; Described high-speed driving motor is connected with bearing seat through high-speed drive shaft, and bearing seat one side has the installation position of wheel box to be detected; The first low-speed shaft that is used for being connected with the right output of wheel box to be detected links to each other with the right side loading motor, and the second low speed rotation beam warp gear case, the 3rd low-speed shaft that are used for being connected with the left output of wheel box to be detected link to each other with the left side loading motor.
Be provided with a pair of gear in the described gear case; Described two gear ratios are 1.
Described gear is double helical spurgear.
Because input end and the output terminal of gear case have certain distance in the horizontal direction, therefore can remedy wheel box horizontal direction centre distance much smaller than half shortcoming of high-speed driving motor external diameter, thereby make near the loading motor of high-speed driving motor side be connected wheel box when connecting, not can because of the centre distance of wheel box horizontal direction to be detected much smaller than high-speed driving motor external diameter half and produce interference.
Because the gear case speed ratio is 1, and gear case inside only has a pair of gear, therefore when testing table carries out torture test, the velocity magnitude of two loading motors is all consistent with direction, for causing two slightly different situations of output terminal moment of torsion of wheel box owing to increased gear case, can come moment of torsion is finely tuned by the testing table control system, thereby can guarantee that two output torques of wheel box to be detected equate.
Owing to when the design gear case, fully take into account the lubricated and heat dissipation problem of gear case, thus this gear case in actual use without any need for cooling and lubricating system, also can not cause the situation of gear case insufficient lubrication and excess Temperature to occur.
Because gear box structure is compact, the coaxiality error that can guarantee high-speed driving electric machine main shaft and wheel box to be detected one axle is controlled in the 0.02mm, and the second low-speed shaft deflection angle that can also guarantee to link to each other between wheel box to be detected and the gear case is less than 7.5 degree.
The utility model is simple in structure, reliability is high and can greatly improve efficient, rotating speed and the moment of torsion control accuracy of testing table.
