Abstract

The invention relates to garage equipment. The purpose of the invention is to improve measurement accuracy, reduce labor intensity and expand technological capabilities. The device consists of a pivot arm 1 rigidly fixed on the axis 2, which rotates in the bearing. The second end of axis 2 is connected via a sleeve to the axis of the primary converter of the angle of rotation of the lever 1, made in the form of a potentiometer, the casing of which is rigidly fixed in the carriage 6 mounted on the guides 7 and 8 of the rotary plate 9 installed with the possibility of rotation in the horizontal plane at an angle equal to 90 ° relative to the base plate 14 with the fixation of these positions with a clamp with a spring. The support plate 14 is rigidly fixed to the rod 18 of the drive for the vertical movement 19 of the device, made in the form of a hydraulic cylinder. The vertical movement actuator is fixed on the beam 20 inside the inspection ditch. A carriage 6 with a pivoting lever 1 is guided along the guides 7, 8 of the pivot plate 9 to the beam of the vehicle being inspected. In this case, both ends of the V-shaped lever 1 are in contact with the bridge beam. Then the carriage 6 is guided along the guides to the frame spar until both ends of the V-shaped pivot arm 1 are in contact with two points of the spar. The difference in the input voltages obtained is proportional to the angular displacement of the tested bridge of the automobile relative to its frame. 6 Il.

The vehicle axles and inspection axles are not necessary. A carriage 6 with a pivoting arm 1 is guided along the guides 7 and 8 of the pivot plate 9 to the beam of the vehicle to be inspected. In this case, both ends of the U-shaped lever 1 are in contact with the bridge beam and the voltage from the potentiometer 5 is fed through the key 25 to the storage capacitor 21 and the repeater 23. Then the carriage is discharged from the bridge bridge along the guides, the rotary plate 9 is released by removing the pin 15 from the hole in the plate 9 and it rotates at a 90 ° angle. This position is locked with a lock. The carriage is guided along guide rails to the frame spar until both ends of the U-shaped pivot arm 1 are in contact with the two points of the spar. At the same time, the voltage from the potentiometer 5 through the switch 26 is fed to the storage capacitor 22 and the repeater 24.
