Abstract
A lubricating structure of a transmission is capable of supplying a lubricating oil with respect to a clutch promptly and stably. The lubricating structure of the transmission includes a first oil passage 53 which extends in a second input shaft 18 from one end side thereof to a first position, and the lubricating oil is supplied from the one end side, a second oil passage 54 which connects to the first oil passage 53 at the first position and extends in the second input shaft 18 to a second position, a first lubrication hole 55 which distributes the lubricating oil to the second clutch 20 at the first position, and a second lubrication hole 56 which distributes the lubricating oil to a transmission mechanism 40 at the second position.
Claims3
A lubricating structure of a transmission, comprising:
- an input shaft which is input with a motive power from a prime mover;
- a transmission mechanism provided rotatably and concentric to the input shaft;
- a clutch which is capable of freely switching between an engagement mode in which the motive power input to the input shaft to the transmission mechanism is transmitted, and to a disengagement mode in which the transmission is shut off;
- a first oil passage extending in the input shaft from one end thereof to a first position corresponding to a position of the clutch, and which is supplied with lubricating oil;
- a second oil passage extending in the input shaft from the first position to a second position corresponding to a position of the transmission mechanism;
- and
- a connecting oil passage which connects the first oil passage and the second oil passage at the first position,
- wherein the input shaft is provided with a first lubrication hole which pierces an inner circumferential surface of the first oil passage to an outer peripheral surface of the input shaft for distributing the lubricating oil to the clutch at the first position, and a second lubrication hole which pierces an inner circumferential surface of the second oil passage to an outer peripheral surface of the input shaft for distributing the lubricating oil to the transmission mechanism at the second position,
- and the one end of the first oil passage is configured to connect to a lubricating oil source.
