Fig. 2.37. Automatic mechanism of a tension: 1 – lever; 2 – tension mechanism; 3 – tension pulley
The automatic mechanism of a tension consists of a tension pulley, the lever and a natyazhitel. The tension pulley supports a belt tension under the influence of force of a spring which settles down in a natyazhitel. Owing to need of work with various suppliers of accessories on the car the mechanism of a tension of one of two types can be used though their principles of work are identical and they are interchanged.
