The invention relates to the transport industry, mainly to the testing of tracked vehicles, and is an improvement of the invention according to the author. St. No. 1180732.

The purpose of the invention is to simplify and accelerate the processing of data, as well as the operational information of the operator on the amount of skidding.

FIG. 1 is a schematic diagram of the device; in fig. 2 shows the principle diagram of the mechanism for moving the frame with the photosensitive layer; in fig. 3 is a graph of the slippage coefficient versus the pull force on the hook.

The device consists of a driven sprocket 1, kinematically associated with the driving 15 sprocket 2 mounted on the driving wheel 3 of the vehicle. Gear 4 is attached to one shaft with a driven sprocket 1 and connected to the axial axial pin 5 through the semi-axle and pinion 6. Between the first semi-axle gear 6 and the second axle pinion 7 there is a satellite 8 rotating around the axis 9, which is connected fixedly to the carrier 10 mounted on gear 11 meshed with gear 12. Gear 12 25 is fixed on the shaft of the tacho generator 13, which is connected by wires 14 to the mechanism 15 for moving the frame 16 to the photosensitive layer installed in front of the oscilloscope 17. On the other hand s second side gear 7 via the axle shaft 30 is connected with a gear 18 which is kinematically linked with the gear 19 fixed to the shaft of the drum 20 coiled with cable 21 on it, which is fastened outside the vehicle.

The vehicle is equipped with a working body 22 (dump, ripper, etc.), which is connected via link 23 to the frame 24 of the vehicle. In the rupture of the link 23, a tensile link 25 is established, which is connected by wires 26 to another channel of the oscilloscope 17. For information of the investigator on the coefficient of slipping, the tacho generator 13 is additionally connected to the measuring device 27.

The movement mechanism 15 consists of a measuring bridge 28 formed by resistors 29-34, the vertex A of which is connected via wires 14 to a tachogenerator 13, and the vertex B is connected to an amplifier 35, the load of which is a reversible electric motor 36, the axis of which bore is kinematically connected with a slider - 50 resistor 33 and with the gear 37 of the frame 16. The frame 16 consists of a substrate 38 on which the photosensitive layer 39 and the rail 40, which is in engagement with the gear 37, are mounted,

through the crown 2 and the chain gear is transmitted to the driven sprocket 1, then through gears 4 and 6 and the half shaft to the semi-axial gear 5. On the other hand, the vehicle, moving forward, with a cable 21 fastened outside the vehicle, unwinds the drum 20. Rotation the drum 20 is transmitted through gears 18 and 19 to the second half-axle gear 7, which 1 is opposed to the gear 5.

In case of equality of theoretical and actual speeds, satellites 8 rotate around axis 9 and gear 11 is stationary.

When skidding, gear 7 has a rotational speed less than gear 5, as a result of which satellites 8 begin to run around gear 7, the carrier 10 and gear 11 are carried along. The rotation of which is transmitted to gear 12 located on the shaft of tacho generator 13. Tahoe-generator 13 produces a voltage that, through the wires 14, is supplied to the displacement mechanism 15 to the vertical A of the measuring bridge 28, which leads to the bridge being removed from the equilibrium state, as a result of which a potential arises at the top B, which enters the input of the amplifier 35, It is converted and fed to the control winding of the reversing electric motor 36. The signal on the control winding drives the measles of the reversing electric motor, the axis of which is kinematically connected with the resistor motor 33 and gear 37. The movement occurs until an equilibrium the state of the measuring bridge of the amplifier 29, which depends on the position of the slide motor 33. The rotational movement of the gear 37 is converted by means of the rail 40 into translational, therefore, the substrate 38 s is fixed The photosensitive layer 39 that is on it will move progressively depending on the signal applied to the top A of the measuring bridge 28, and if the input signal is proportional to the slipping factor, and the oscilloscope beam opens / falls depending on the force on the hook Rcr, on the photosensitive layer curve 5 is displayed directly (fig. 3) is proportional to the coefficient of slipping (Pk |,), where S.i is the path of the beam, the propionic Pcr, and S ,, is the path of the beam, the proportionality of the coefficient of slipping b.
