The present disclosure includes a carrier supported on the vehicle body. a ring gear installed such that a rotation axis thereof is concentric with a central axis of the carrier, a wheel hub splined to the ring gear, a sun gear having a rotation axis parallel to the rotation axis of the ring gear and installed to have a variable inter-axis distance, the sun gear being configured to receive power from outside, a final gear supported on the carrier to be meshed with the ring gear, a link mechanism interconnecting the sun gear and the final gear such that a connection angle changes depending on a change in the inter-axis distance between the sun gear and the ring gear, and a gear train to continuously establish a power transmission state between the sun gear and the ring gear regardless of the change in the inter-axis distance.

Driving device for vehicle

The present disclosure includes a ring gear, a final gear meshed with the ring gear, a carrier rotatably supporting the final gear, a sun gear having a rotation axis parallel to the rotation axis of the ring gear and installed to have a variable inter-axis distance, the sun gear being configured to receive power from outside, a link mechanism interconnecting the sun gear and the final gear so a connection angle changes depending on a change in the inter-axis distance between the sun gear and the ring gear, a gear train provided in the link mechanism to continuously establish a power transmission state between the sun gear and the ring gear regardless of the change in the inter-axis distance between the sun gear and the ring gear, and a carrier housing integrally coupled to the carrier and encasing the sun gear, the carrier, the ring gear, and the link mechanism.

A universal driving device includes a ring gear, a sun gear having a variable inter-axis distance with respect to a rotation shaft of the ring gear, a gear train including a series of gears configured to connect the sun gear and the ring gear, link mechanisms configured to accommodate a change in an inter-axis distance between the sun gear and the ring gear and rotatably connected with respect to each other to continuously maintain a power transmission state between the sun gear and the ring gear, a carrier configured to support a rotation shaft of a final gear engaged with the ring gear, among the gears constituting the gear train, a sun gear bearing positioned between the rotation shaft of the sun gear and each of the link mechanisms, and a sleeve positioned between the sun gear bearing and each of the link mechanisms.

Universal driving device

A universal drive including a ring gear, a sun gear in which a sun gear axis is moveable relative to a ring gear axis of the ring gear, a gear train constituted by a series of gears configured to connect the sun gear and the ring gear to each other, a link mechanism connected to the sun gear and the ring gear in the state in which relative rotation therebetween is allowed such that a power transmission state between the sun gear and the ring gear is continuously maintained while accommodating a change in the inter-axis distance between the sun gear and the ring gear, a carrier installed so as to support a rotating shaft of a final gear engaged with the ring gear, and a sliding member located between at least one of the gears and the carrier.

Universal drive

A gear train includes at least four gears sequentially engaged, multiple links configured to support the rotation shafts of the gears, and pins configured to fix the rotation shafts of the gears to the link, wherein the pins are installed such that, among the rotation shafts of the gears, two non-adjacent rotation shafts have both ends fixed to the link and one of adjacent rotation shafts has only one end fixed to the link.

Linkage structure and universal driving device using same

A universal driving device includes a ring gear, a sun gear installed such that the shaft distance between a rotation shaft of the sun gear and a rotation shaft of the ring gear is changeable, and a split gear disposed between the sun gear and the ring gear, and configured to split power, received from the sun gear through one path, into multiple paths and transmit the power to the ring gear.
