IPC: F16H15/38
Filed: 2011-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission which prevents hunting or settles the hunting in an early stage when starting a prime mover.SOLUTION: A trunnion 15 is tilted to change the speed change ratio of an input side disk to an output side disk by displacing the trunnion 15 along the axial direction of a pivot 14 from the neutral position at which the trunnion 15 is not tilted by a driving device 32. There are provided coned disk springs 38, 39 keeping a state in which the position of the trunnion 15 along the axial direction of the pivot 14 is substantially matched with the neutral position where the trunnion 15 is not tilted when the driving device 32 is in a non-operational state. Thus, during the time in which the hydraulic pressure in a hydraulic pressure chamber is not sufficiently increased, the reciprocating motion of the driving device can be stopped, and consequently the hunting can be prevented or can be settled in an early stage when starting a prime mover. In other words, when the hydraulic pressure in the hydraulic pressure chamber is low, the reciprocating motion of the driving device is fixed, and when the hydraulic pressure is increased, the operation of the driving device similar to that of the conventional one can be achieved.
