Description

 . lt

Iaofetenae refers to the most advanced Nvu, namely E test equipment. And can be used for ESvffiTasfHH with high accuracy of workloads times 1H1X mechanical transmissions, transmissions and drives.

Most importantly, according to the technical essence and the achieved efficiency, the equipment is: Mechanical transmission test 1.

However, the control system of the known load device does not allow with the required accuracy to extrude the errors made by the load device when reproduced in the driver action.

The purpose of the invention is to improve the accuracy of reproduction of load modes.

Claims (1)

The stand contains engine 1, connected through 2 clutches with a gearbox of 3 gears, connected with two gears with gears 4 with power transmission; The transmission 5, which is connected to an increase in 5 gear reducers with the help of the "Trash 6". At one end of the output shaft of the reuctor 7, a replaceable flywheel weight 8 is installed, and the second one is. Through the special coupling 9, the output shaft is connected to an executing unit with a ROYSTOB 10, for example, an electromagnetic powder brake, which is electrically connected to the output of an ijaiiffij torque load moment (one) or more) consisting of a pulsed power amplifier 11 controlled by latitude by a pulse-type modulator 12, which receives a control. a signal from the adder 13. The elements 14 of the comparison of the feedback circuit are electrically connected with the li. 5 and 16 are the inputs of the peryjmpoBamasi block at the moment of load. Ushshtel 15 is electrically connected to the converter 17 of the moment of the transmission element under study, of which several can be installed, and the amplifier 16 is electrically connected to the converter of moment 18, one shh more, installed at the output of the actuator Y. The adder 13 is electrically connected to the switch 19, 6 the latter, in turn, with an analog computational 2S3 computer, a tape recorder 21, a reader 22 with a paper chart and a handheld unit 23. The tacho generator 24 is mechanically connected to the driving drive shaft 1, and Ctrically, with an analog computer 20. The load device works as follows. The transmission under test is driven by engine 1 through the splicing clutch 2 and gear box 3. Next, the torque is transmitted through the cardan gears 4 to the test gear 5 and through clutch 6, the gearbox 7 to the speed reducer 9 to the loaded gear. using the foot-fixer of the device 10, controlled by a direct control channel - an IS adder, an air-impedance modulator 12 and a pulse voltage amplifier 11. The adder 13 algebraically generates a feedback signal (OS) from the master signals (ES), which is accessed via a switch, 19 from one of the sources of the analog computer 2O, tape recorder 21, reader 22c paper or handheld sensor 23,. A feedback signal is generated;. a comparison element 14, which, from the amplified signal of the torque converter 18 of the actuating device 10. You receive an amplified signal from the load converter 17 of the transmission element under study. Signals lead prices to the same scale. Thus, the controlled signal, which is supplied from the adder 13 to the switchgear-modulator 12, the switching power amplifier 11, and the actuator 10, is always proportional to the driver. signal and the signal of the detected error, which leads to its elimination from the error, due to the sensitivity threshold of the linear amplifiers 15 and 16, the signal about the angular speed of rotation of the shaft of the engine 1 generates a tachogenerator 24 into the system. This signal is used during the simulation process the traction from the place of the machine-tractor unit, For the same price is the flywheel mass 8 and the special MyxjjTa 9. The introduction of an additional circuit that connects the torque converter installed on the actuator with the input of the control unit Oment loading, will allow with necessary and. Accuracy of detecting errors created by the load device when reproducing the deer and specifying the action. Claims of the invention A load device for dynamic testing of mechanical transmissions, comprising an initial device with a load torque control unit, connected to the input of the latter converter, designed to be mounted on the test mechanical transmission, which is With a purpose of precision reproducing the HarpyaoHHbix modes, it is equipped with an additional torque converter located on the recovery device connected to the input of the moment-to-torque unit and the load.
