SURELY TRANSMITTING CLUTCH FOR DRIVING POWER DISTRIBUTOR AND DIFFERENTIAL GEAR OF AUTOMOBILE, DRIVING POWER DISTRIBUTOR DEVICE AND DIFFERENTIAL GEAR HAVING SAID CLUTCH AND METHOD FOR OPERATING IT

摘要

PURPOSE: To make a clutch operable at proper timing by connecting a control apparatus to two clutch parts or revolving speed sensors installed in the power transmission system relevant to the clutch parts in the input sides and to a single operation member in the output side and acting on the operation member at the time of passing a prescribed slip limit value. CONSTITUTION: A signal processing part 80 receives, from sensors 22, 23, pulses corresponding to teeth or marks of a transmission gear part to be scanned. The sensor 22 is engaged in the teeth 58 of a spline 12 or a mobile sleeve 53 and the sensor 23 is engaged in the teeth of a driving gear or the teeth of a pinion 47. Those pulses are converted into revolving speed signals by converters 85, 86. Both revolving speed signals are supplied to an adder 91 for generating difference through conductive wires 88, 89, so that slip signals are generated in a conductive wire 92. In this case, the slip means the revolving speed difference between both clutch parts 16, 17 and the revolving speed difference is therefore obtained independently of the arrangement of the sensors owing to a signal processing part 80.
