The present invention provides an auxiliary machinery belt system comprising a pair of a left arc spring (7-1) and a right arc spring (7-2) and a torque filter (100, 100-1). The left arc spring (7-1) and the right arc spring (7-2) have a spring constant value set as rotation torque of a crank shaft (300-1) transferring power of an engine (300) to rotation torque and are arranged symmetrically in left and right directions. The torque filter (100, 100-1) has a spring constant value set as threshold torque by irregularity of the crank shaft (300-1) and comprises an impact spring (10) positioned in the section where the left arc spring (7-1) and the right arc spring (7-2) face each other. Impact noise of an end stop (8) and a hub (1) in threshold torque, which is a preset value or less, can be alleviated. |
