Here, therefore visible balancing device is only carried by friction element 2.
Balance rivet 11 locally increases quality to friction element, this allows more easily balance transmission equipment.
(amplification that the figure is Fig. 2) that can preferably see such as in Fig. 3, each balancing device is herein by being fixed on friction
The formation of solid rivet 11 on element 2.These balance rivets have two heads 21,22 of clamping friction element 2.One of them
Head 22 is heavier than another head 21.The rivet head 22 of more weight can be described as " balance head ".
In Fig. 3, it is noted that the axial length of balance rivet 11, especially its axial length for balancing head 22 are than plate 8
Axial width it is bigger.
In the Fig. 4 of torque transmission device for showing Fig. 3 without 50 ground of torque limiter, it is seen that 5 part of guidance washer
Ground has material removal portion.Here, the circular contour of washer 5 is in the form of plat part locally with jagged.
