Abstract

PURPOSE: To make a desired torque loadable during the driving by connecting a rotary cylinder to the power circulating rotary shaft system of a gear speed changer.
CONSTITUTION: A rotary cylinder 11 is connected between the rotary shaft 2a of a pinion 2 of a gear speed changer 3 and the rotary shaft 5a of a pinion 5 of a gear speed changer 6, and is connected further to a control circuit 21 through a fixed joint 20. As a result, a desired torque signal A from an input signal emitter 22 and a detecting torque signal B from a torque detector 27 are compared in a comparator 23. The deviation C is supplied as input to a servo valve 26 through an amplifier 24, and a hydraulic fluid from a hydraulic oil source 25 is supplied through the fixed joint 20 to a hydraulic fluid chamber 14 or 15 of the rotary cylinder 11, and the rotary shafts 2a and 5a are twisted towards the torque increasing or decreasing direction, thus a desired torque is continuously afforded between the rotary shafts 2a and 5a.
