Abstract
The utility model relates to an impulsive torque test device. A drive motor of the device is transmission-connected with a flywheel system by a transmission device; the flywheel system is connected with a sample driving axle by a transmission shaft; the tire nut of the driving axle is connected with a middle support; one end of a force arm is connected with the driving axle, and the other end is connected with a tension and pressure sensor. The device overcomes the shortcomings of fragileness and high cost when testing the impulsive torque of the impulsive torque sensor in the prior art. The reaction torque of the impulsive torque acts on the force arm due to the interaction of force when the sample driving axle is imposed to the torque. The driving axle is connected with the force arm, thus the force can be transmitted to a tension and pressure sensor by the force arm, and then the tension and pressure sensor tests the force; the impulsive torque borne by the driving axle can be easily tested through calculation. The impact resistance performance of the tension and pressure sensor is excellent and the cost is far lower than that of a torque sensor.
Description
Affiliated technical field
The utility model relates to a kind of impulsive torque proving installation, especially can test the suffered impulsive torque of drive axle on the drive axle shock table.
Background technology
When on the drive axle shock table, carrying out torsion-testing at present, often adopt torque sensor to test the input impulsive torque of drive axle, because general torque sensor shock resistance is poor, when therefore torque sensor being used on this kind testing table, its life-span is shorter, and because torque sensor is relatively more accurate testing tool, its cost is also higher.
Summary of the invention
In order to overcome torque sensor in test fragile and shortcoming that cost is high during impulsive torque, the utility model provides a kind of new impulsive torque proving installation, and this proving installation not only can be tested the suffered impulsive torque of drive axle accurately, and simple in structure, reliability height, cost are also low.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of impulsive torque proving installation, comprise control system, control system controlling and driving motor, belt gear and clutch apparatus, detent carry out impulse test, adjust according to the big or small impact cycle and the impulsive torque of impulsive torque simultaneously; Drive motor is connected with fly wheel system by gearing, fly wheel system is connected with testing sample (drive axle) through transmission shaft, testing sample (drive axle) assembly links to each other with intermediate support by the tire bolt at two ends, one end of the arm of force is connected with testing sample, and an other end links to each other with pull pressure sensor.
Under the acting in conjunction of the arm of force and intermediate support, the testing sample drive axle " floats " aloft, and this limits the degree of freedom of drive axle axle housing along the rotation of semiaxis axis direction by this connected mode.
The center line of pull pressure sensor of the present utility model is vertical with the arm of force, and its upper end links to each other with the arm of force, and the lower end links to each other with ground by connecting rod.Guard system is housed on the arm of force, prevents damage equipment and injury staff under the situation of danger.
The utility model is at testing sample (drive axle) when being subjected to impulsive torque, because the interaction of power, the reaction torque of impulsive torque acts on the arm of force, so, power will be delivered on the pull pressure sensor by the arm of force, and pull pressure sensor is tested suffered power, and according to formula: the arm of force * pulling force=moment of torsion as can be known, the pulling force and the arm of force surveyed are multiplied each other, can measure the suffered impulsive torque of drive axle easily.Because the shock resistance of pull pressure sensor is fine, so, little to its life-span influence when being subjected to impulsive torque, and its cost is far below the torque sensor cost.
The beneficial effects of the utility model are, can reduce testing cost, can greatly improve the life-span of the use of testing table in the test impulsive torque, and this proving installation are simple in structure, reliable.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
Fig. 1 is the utility model structure and uses synoptic diagram; Fig. 2 is the A-A view of Fig. 1.
1. drive motor among the figure, 2. belt gear and arrangement of clutch, 3. fly wheel system, 4. transmission shaft, the 5. arm of force, 6. intermediate support, 7. brake system, 8. drive axle, 9. guard system, 10. high dynamically pull pressure sensor, 11. axle housings.
Embodiment
Among Fig. 1, the arm of force of the present utility model (5) links to each other with drive axle (8), and fly wheel system (3) is connected with drive axle (8) input flange through transmission shaft (4), and drive axle (8) assembly links to each other with intermediate support (6) by the tire bolt at two ends.When carrying out impulse test, the whole test system is under the drive of drive motor (1) and belt gear and arrangement of clutch (2), fly wheel system (3), transmission shaft (4), intermediate support (6), drive axle (8) begins to rotate, when the rotating speed of flywheel reaches the rotating speed that testing table sets, the brake system (7) of the control system controlling and driving bridge of testing table is carried out emergency brake, the energy conversion of fly wheel system this moment (3) is that impulsive torque acts on the drive axle (8), after drive axle (8) is subjected to impulsive torque, because the interaction of power, drive axle (8) impulsive torque that it is suffered is delivered on the arm of force (5), the arm of force (5) is delivered to power again on the high dynamically pull pressure sensor, by the moment of torsion formula: the arm of force * pulling force=moment of torsion as can be known, the pulling force and the arm of force surveyed are multiplied each other, can measure the suffered impulsive torque of drive axle easily.
Among Fig. 2, an end of the arm of force (5) is fixedlyed connected with the axle housing (11) of drive axle, and the other end is connected with high dynamically pull pressure sensor (10).In addition, when carrying out impulse test, impulsive force is often bigger; relatively more dangerous during test, for the safety of protection equipment and testing crew, installed guard system (9) on the arm of force (5) additional; guard system (9) is a protective jacket, and the arm of force (5) is inserted in the protective jacket upper end, and protective jacket is fixed in ground.
