Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] see figure 1 A crankshaft torsional damper assembly shown includes a pulley 1 and a hub 3 that is mated with the crankshaft, and is characterized in that: it also includes a pulley located between the inner circle of the pulley 1 and the outer circle of the hub 3 The damping rubber ring 2.
[0022] see figure 2 , the inner circle of the pulley 1 is equidistantly provided with a plurality of large grooves 4 of the same size, and the outer circle is provided with belt grooves.
[0023] see image 3 , the outer circle of the vibration-damping rubber ring 2 is equidistantly provided with a plurality of large bosses 5 of the same size, and the inner circle is equidistantly provided with a plurality of small grooves 6 of the same size, and each of the large bosses 5 Number is equal to the number of the large groove 4;
[0024] see Figure 4 , the outer circle of the...
