Description
Affiliated technical field
The present invention relates to a kind of in rotating speed of setting and torque range, can be continuously and change torque ratio and rotating ratio between power input shaft and the pto arbitrarily, can also change the buncher of pto sense of rotation arbitrarily.
Background technique
The buncher of known this class function is to carry out speed change by the contact radius that changes driving wheel and follower and driving belt, or carries out speed change by the contact radius that changes driving wheel and follower at present.Its buncher is to rely on the friction between driving wheel and follower or driving wheel and follower and driving belt to realize transmission of power, described driving wheel is meant the power input wheel that is connected on the power input shaft, and described follower is meant the power output wheel that is connected on the pto.The stepless speed variator of mature and reliable has (Continuously Variable Transmission) speed changer (hereinafter referred to as the CVT speed changer) and continues to use improved other buncher of CVT speed changer principle at present, the principle of CVT speed changer is to carry out speed change by the contact radius that changes driving wheel and follower and driving belt, realizes transmission of power by the friction between driving wheel and follower and driving belt.Though it is more progressive to some extent than CVT speed changer to continue to use improved other buncher of CVT speed changer principle, it relies on, and friction comes the power delivery mode of transferring power still not change between driving wheel and follower and driving belt.A lot of locomotives all need the speed changer of high pulling torque bearing capacity and high pulling torque transmittability, and high pulling torque as herein described is meant the moment of torsion that 1500 (NM) are above.The stepless speed variator of power delivery mode with the friction transferring power, high pulling torque bearing capacity and high pulling torque transmittability are arranged, high to technology, technology, the material requirements of producing parts, so far people also can't produce the stepless speed variator of the high pulling torque bearing capacity and the high pulling torque transmittability of reliable maturation, with the stepless speed variator of power delivery mode of friction transferring power, its parts that participate in friction occur skidding and because of the damage easily of skidding easily.From the above as seen, existing buncher has the friction adopted to come the shortcoming of transferring power, and because of adopting this power delivery mode to cause the little and transfer of torque minor defect of its bearing torque, also has the easy shortcoming of damaging of friction means.
Summary of the invention
Adopt the friction between driving wheel and follower and these three parts of driving belt to come the deficiency of transferring power in order to overcome existing buncher, and therefore cause the deficiency that its bearing torque is little and transfer of torque is little and friction means damages easily.The invention provides a kind of stepless speed variator, this stepless speed variator adopts fluid to come transferring power, and bearing torque is big, transfer of torque is big, life-span is long, the technical solution adopted for the present invention to solve the technical problems is: adopt impeller to come power between transferring power input shaft and the pto in conjunction with fluid, angle and direction by change and control impeller blade is realized rotating ratio, the function of the forward or reverse of torque ratio and pto, it is mainly constructed, by shell, power input shaft, the impeller of variable-vane angle, blade angle control system, fluid,
