Abstract:
A clutch operating apparatus comprising:a control valve for controlling pressure oil to connect and disconnect a clutch; a clutch pedal supported to be pivotable from a home position thereof; a bracket pivotable with said clutch pedal; an interlocking mechanism including an interlocking member for operatively interconnecting said bracket and said control valve to operate said control valve with a pivotal movement of said clutch pedal; a coupling mechanism for coupling said bracket to one end of said interlocking member, said coupling mechanism having a lost motion mechanism which includes a connecting pin disposed on one of said bracket and said interlocking member, and receiving bores defined in the other of said bracket and said interlocking member in the form of slots for receiving said connecting pin, wherein said lost motion mechanism does not allow said clutch pedal to transmit its pivotal displacement to said control valve during an initial pivotal displacement of said clutch pedal, and allows said clutch pedal to transmit the pivotal displacement to said control valve in response to completion of said initial pivotal displacement; a first spring operatively connected to said clutch pedal for applying a resisting force to said clutch pedal toward said home position in response to said initial pivotal displacement; and a second spring operatively connected to said interlocking member for applying a second resisting force to said clutch pedal toward said home position in response to completion of said initial pivotal displacement.
