Abstract
The invention provides a fatigue test stand for a gearbox of a passenger vehicle. A high-speed driving motor, a bearing support, a gear case, a left loading motor and a right loading motor are arranged on the testing stand, wherein the high-speed driving motor is connected with the bearing support through a high-speed transmission shaft; one side of the bearing support is provided with a mounting position of a gearbox to be detected; a first low-speed transmission shaft used for being connected with the right output of the gearbox to be detected is connected with the right loading motor; and a second low-speed transmission shaft used for being connected with the left output of the gearbox to be detected is connected with the left loading motor through the gear case and a third low-speed transmission shaft. The fatigue test stand not only can stagger the loading motor on one side of the high-speed driving motor with the high-speed driving motor, but also has the advantages of simple structure, high reliability, and high precision for rotational speed and torque control of the testing stand.
Description
Technical field
The present invention relates to a kind of fatigue test stand for gearbox of passenger vehicle.
Background technology
At present in fatigue test stand for gearbox of passenger vehicle, because the centre distance of wheel box horizontal direction is much smaller than the half of high-speed driving motor external diameter, in order to the loading motor of high-speed driving motor side and the position of high-speed driving motor are staggered, the mode that general employing high-speed driving motor is connected with high-speed belt is connected with an axle of wheel box, because belt often produces speed discrepancy in operational process, and the efficiency of belt is also lower, therefore the mode adopting high-speed driving motor to be connected with high-speed belt often causes testing table rotating speed, moment of torsion control accuracy is low, and high-speed belt reliability is also poor.
Summary of the invention
In order to overcome when prior art high speed drive motor is connected with high-speed belt that efficiency is low, reliability is poor and testing table rotating speed, moment of torsion control accuracy difference deficiency, the invention provides a kind of fatigue test stand for gearbox of passenger vehicle, the loading motor of high-speed driving motor side and high-speed driving motor position can not only stagger by it, and structure is simple, reliability is high, testing table rotating speed, moment of torsion control accuracy are high.
The technical solution adopted for the present invention to solve the technical problems 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 there is the installation position of wheel box to be detected bearing seat side; For being connected with right side loading motor with right the first low-speed shaft be connected that exports of wheel box to be detected, for being connected with left side loading motor with left the second low speed rotation beam warp gear case, the 3rd low-speed shaft that are connected of exporting of wheel box to be detected.
A pair gear is provided with in described gear case; Described two gear ratios are 1.
Described gear is double helical spurgear.
Because the input end of gear case and output terminal have certain distance in the horizontal direction, therefore the shortcoming of wheel box horizontal direction centre distance much smaller than high-speed driving motor external diameter half can be made up, thus make, when the loading motor of high-speed driving motor side is connected with wheel box to be detected, interference to be produced because of the centre distance of wheel box horizontal direction to be detected much smaller than the half of high-speed driving motor external diameter.
Because gear case speed ratio is 1, and gear case inside only has a pair gear, therefore when testing table carries out torture test, the velocity magnitude of two loading motors is all consistent with direction, for owing to adding the situation that gear case may cause wheel box two output terminal moments of torsion slightly different, can be finely tuned moment of torsion by testing table control system, thus can ensure that wheel box to be detected two output torques are equal.
Owing to fully taking into account lubrication and the heat dissipation problem of gear case when design gear case, therefore this gear case in actual use without any need for cooling and lubricating system, gearbox lubrication is bad and temperature is too high situation also can not be caused to occur.
Because gear box structure is compact, can ensure that the coaxiality error of high-speed driving electric machine main shaft and a wheel box to be detected axle controls within 0.02mm, and can also ensure that wheel box to be detected is less than 7.5 degree with the second low-speed shaft deflection angle be connected between gear case.
Structure of the present invention is simple, reliability is high and can greatly improve the efficiency of testing table, rotating speed and moment of torsion control accuracy.
