Abstract

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.

Dependent claims

A drive power connecting/disconnecting device comprising:

a differential housing which accommodates therein a differential mechanism;
a first shaft supported on a boss portion of the differential mechanism and rotating a first rotational body which transmits a drive power distributed at the differential mechanism;
a second shaft provided coaxially with the first shaft and transmitting the drive power to a wheel axle transmitted from the first rotational body by a second rotational body which is positioned opposing to the first rotational body;
a connecting/disconnecting member provided axially movably on an outer periphery of the second shaft and moving the second rotational body in an axial direction relative to the first rotational body to thereby connect or disconnect the first shaft and the second shaft,
a supporting member provided on the outer periphery of the second shaft and supporting the connecting/disconnecting member to be movable along in the axial direction;
a stationary element provided on the outer periphery of the second shaft such that the stationary element is arranged opposed to the outer periphery of the connecting/disconnecting member in a radial direction and moving the connecting/disconnecting member along in the axial direction by energization of a coil;
a shaft cover covering at least an outer periphery of the second rotational body and connected to the differential housing;
a first pivotally supporting portion provided between the first shaft and the second shaft and pivotally supporting one end of the second shaft;
and
a second pivotally supporting portion provided inside of the shaft cover and pivotally supporting another end of the second shaft, wherein
the stationary element is supported by an inner wall of the shaft cover and a clearance between the stationary element and the connecting/disconnecting member in the radial direction is provided.
