Checking the shock absorber on the stand (VAZ-2101)

To check the performance of the shock absorber, its operating diagram is taken on a dynamometer stand. The operating diagrams should be taken according to the instructions after at least 5 operating cycles have been completed, at a shock absorber operating fluid temperature of (20±5)°C, a rotation speed of 60 rpm and a rod stroke length of 80 mm for the front and 100 mm for the rear shock absorbers.

The resistance of the recoil and compression strokes is determined by the largest ordinates of the corresponding diagrams. The curve of the diagram (Fig. 123) should be smooth, and at the transition points (from recoil stroke to compression stroke) without sections parallel to the zero line.



The highest point of the recoil stroke curve at a scale of 4.8 kgf per 1 mm should be located from the zero line at a distance A equal to 21-28 mm for front shock absorbers, 19-26 mm for rear ones. The highest point of the compression stroke curve at the same scale should be located from the zero line at a distance B equal to 3.5-6.5 mm for front shock absorbers, 4.5-7.5 mm for rear ones. After checking, remove the shock absorber from the stand and, if necessary, disassemble it and replace damaged or worn parts. To make sure that the shock absorber is in good working order, repeat the test.
