摘要： A coupling structure includes a shaft, a tube, and a connection assembly. An end of the shaft is formed with a plurality of axial insertion troughs extended in an axial direction and arranged in an alternate manner. The tube includes a penetration-axle hole formed in a center thereof and corresponding to the penetration-axle section of the shaft. A plurality of radial insertion troughs, in the form of a recessed surface, are formed in an inner circumferential surface of the penetration-axle hole of the tube. The connection assembly includes a coupling block that has an outer circumference formed with a plurality of radial insertion blocks corresponding to the radial insertion troughs of the tube and a plurality of axial insertion blocks corresponding to the axial insertion troughs of the shaft, so that a fastening member may be used to selectively fasten the coupling block between the shaft and the tube.

摘要： A compact transmission, in particular for use within a single-wheel drive unit, includes a gear carrier fixed to the frame, which has a continuous central recess, and a main transmission having an internally toothed ring gear rotatably mounted on the outside of the gear carrier, externally toothed gears arranged in front of the one of the end faces of the gear carrier and meshing with the ring gear, and an input sun shaft. The compact transmission further includes a transmission pre-stage arranged within the central recess, and a pre-stage input shaft having an externally toothed pre-stage sun wheel, a pre-stage ring gear, and at least one pre-stage intermediate gear meshing with both the pre-stage sun wheel and with the pre-stage ring gear. An additional carrier is fastened to the transmission carrier, via which the pre-stage intermediate gears are held captively in the central recess.

摘要： A carrier includes a first carrier portion and a second carrier portion. The first carrier portion includes a gear housing space that houses a planetary gear, an opening that opens the gear housing space toward the second carrier portion and allows the planetary gear to fit into the gear housing space, and a first support hole that supports a first end portion of the planetary support shaft. The second carrier portion includes a cover portion that covers the opening, a second support hole that supports a second end portion of the planetary support shaft, and a joining portion that detachably joins the second carrier portion to the first carrier portion. The joining portion is joined to the first carrier portion by being tightened in a direction aligned with a direction of an axial core of a sun gear.

摘要： Separate structural units for an inner gear and a housing of a planetary gear device include an inner gear with a first raised portion formed on the outer peripheral surface of the inner gear, where the first raised portion extends towards in a direction that is inclined with respect to the axial direction of the inner gear. A housing includes a second raised portion formed on an inner peripheral surface, where the second raised portion extends in a direction that is inclined in respect to the axial direction. The housing contains the inner gear such that there is a gap formed between the inner peripheral surface of the housing and the outer peripheral surface of the inner gear. Movement of the inner gear within the interior of the housing is limited through linear contact of the first raised portion and the second raised portion.

摘要： Provided is a dual clutch transmission. First and second input shafts are mounted concentrically. First and second output shafts are mounted in parallel to the first input shaft and respectively include output gears engaged with a ring gear of a differential. The rotations of first and second gears are restrained by the first input shaft. The rotations of third and fourth gears are restrained by the second input shaft. The rotations of fifth and sixth gears engaged with the second and third gears, respectively, are restrained by the first output shaft. The rotation of a seventh gear engaged with the first gear is restrained by the second output shaft. An eighth gear is engaged with the second gear to be rotatable about the second output shaft. The rotation of a ninth gear engaged with the fourth gear and restrained by the eighth gear is restrained by the second output shaft.
