The drive power connecting/disconnecting device includes a second shaft disposed coaxially to a first shaft so as to transmit drive power to a wheel axle, a connection/disconnection member which moves a second rotational body along an axial direction with respect to a first rotational body, and which is capable of moving in the axial direction so as to make or break engagement between the first shaft and the second shaft, a supporting member, a shaft cover which covers at least the periphery of the second rotational body, a first pivotally supporting portion which is disposed between the first shaft and the second shaft so as to axially support one end of the second shaft; and a second pivotally supporting portion which is disposed inside the shaft cover so as to axially support the other end of the second shaft.

Drive power connecting/disconnecting device

A driving force connecting/disconnecting device includes an externally toothed spline provided on an outer periphery of one of a first shaft member and a second shaft member, an internally toothed spline engageable with the externally toothed spline, a sleeve provided with the internally toothed spline which is engageable with the externally toothed spline by moving in an axis line direction and connecting the first shaft member and the second shaft member for transmitting the driving force, a moving mechanism which moves the sleeve in the axis line direction, a holder which holds the sleeve and the moving mechanism, and a positioning mechanism for positioning the holder in the axis line direction by bringing the holder into contact with the one of the first shaft member and the second shaft member thereby to mount the holder to the first shaft member.

Driving force connecting/disconnecting device

A lubricating structure for a speed reducer includes: a case; a first reduction gear pair provided inside the case; a second reduction gear pair provided inside the case; a first catch tank arranged inside the case; a second catch tank arranged inside the case; a partition member that includes a partition wall that partitions an inside of the case into a first accommodation space in which the first reduction gear pair is accommodated and a second accommodation space in which the second reduction gear pair is accommodated; a first oil passage communicating with the first accommodation space and configured to guide lubricating oil to the first catch tank; a second oil passage communicating with the second accommodation space and configured to guide lubricating oil to the second catch tank; and a communication port provided in the partition member and communicating the first oil passage with the second oil passage.

Lubricating structure for speed reducer

A lubricating structure for a speed reducer includes: a case; a reduction gear provided inside the case, the reduction gear being configured to rotate around a rotation axis; a catch tank configured to store part of lubricating oil scooped up by the reduction gear; an oil passage provided in the side wall, the oil passage being configured to guide the lubricating oil, scooped up by the reduction gear, to the catch tank; a rib formed on the side wall so as to radially extend, the rib being configured to guide the scooped-up lubricating oil toward a radially inner side; and a groove provided at an end edge of the rib of the side wall, the lubricating oil trapped by the rib being introduced into the groove, and the groove communicating with the lubricating oil supply object.

A lubricating structure for a reduction gear includes a catch tank for holding a part of lubricating oil which is held on the bottom part of a transaxle case and which is supplied, by being scooped up, to each portion to be lubricated, a first oil passage provided within the transaxle case and guiding lubricating oil, which has been scooped up by a first driven gear, to the catch tank and a second oil passage provided within the transaxle case so as to be displaced from the first oil passage in an axial direction relative to the case and guiding lubricating oil, which has been scooped up by a second driven gear, to the catch tank.

Lubrication structure for reduction gear

A rotary shaft and a seal mechanism are provided. The rotary shaft extends into outside air outside a case via a shaft hole provided in the case of a drive system. The seal mechanism prevents entry of foreign matter from the outside air into the shaft hole. The case includes a canopy portion and a recessed portion. The recessed portion is recessed coaxially with the canopy portion from an end face of the canopy portion in the direction of the axis. The seal mechanism includes a deflector and a seal member. The deflector is fixed to the rotary shaft in a liquid-tight manner, and extends into the recessed portion. The seal member is an elastic body. The seal member is fixed in the shaft hole in a liquid-tight manner, and is in sliding contact in a liquid-tight manner with the rotary shaft and the deflector.
