In a vehicle in-wheel motor drive device, an in-wheel motor unit is supported by a supporting member in a posture in which a direction from a first axis to a center-of-gravity position of the in-wheel motor unit has a horizontal direction component in an axially perpendicular plane perpendicular to the first axis, and the supporting member is provided with a stopper brought into contact with the in-wheel motor unit to regulate vibrations having a component in a vertical direction around the first axis of the in-wheel motor unit before an elastic member reaches an elastic limit.

The present invention is aimed to provide a carrier assembly which can be made small in size while securing a sufficient fixing strength between a first carrier plate and a second carrier plate. The second carrier plate () has a plurality of connection elements () bent toward the first carrier plate () to weld and fix the outwardly projected end portions () of the connection elements with the outwardly projected end portion of the first carrier plate () by electron beam welding. The connection elements each have a base portions () formed with a notch (). The notch () thus formed makes a gap S between the base portion of the connection element and the corner portion () of the pinion gear.

A hybrid transaxlethat is a transmission is provided with a junction surfacethat contacts a junction surface of an internal combustion engine. A bolt span portionof the junction surfaceis provided with a protrusion portionthat elastically deforms so that the internal combustion engine-side junction surface and the hybrid transaxle-side junction surfaceclosely contact each other.

Fastening structure of power unit

A torque limiter mounted on a hybrid vehicle includes an output plate, an input plate including a first region facing a first main surface of the output plate and a second region facing a second main surface of the output plate, a friction member provided on the first main surface of the output plate and disposed between the first main surface and the first region, and a biasing member being in contact with the second main surface of the input plate, for biasing the output plate toward the first region.

Torque limiter and power transmission device

A hybrid vehicle power transmission device provided with a power distribution mechanism composed of a planetary gear device for distributing motive power of a drive source to a motor and an output shaft is further provided with a damper device in a power transmission path between the power distribution mechanism and a first motor. Consequently, the damper device receives only reaction torque dealt by the first motor through the power distribution mechanism with respect to drive torque of an engine. Thus, since the torque transmitted to the damper device is smaller than the drive torque of the engine, the torque capacity of the damper device can be decreased and the size of the damper device can be reduced. As a result, the overall size of the power transmission device can be similarly reduced.

A planetary gearset provided with a sun gear, a ring gear, and a carrier that rotatably retains a plurality of pinion gears arranged between the sun gear and the ring gear as elements, in which one of the elements is made a fixed element and one of the other elements is made a rotating element, and which transmits torque between that rotating element and an external member provided in a location eccentric with respect to that rotating member. The planetary gearset is constructed such that the fixed element is movably retained in the direction of a load from the transmission of torque between the rotating element and the external member, and the load from the transmission of torque between the rotating element and the external member is received by a fixed portion that rotatably retains that rotating element.

Planetary gearset

A drive system for an electric vehicle, which can make the number of parts as small as possible and minimize the space for arranging the parts in a direction perpendicular to the axis. Between a motor acting as a prime mover and left and right output shafts, there are interposed toroidal type continuously variable transmissions which can individually control their gear ratios and their forces for thrusting power rollers. The RPMs and torques of left and right wheels can be individually controlled, and the differential rotation between the left and right wheels can be smoothly established by the continuously variable transmissions.

Toroidal drive system for electric vehicles

An apparatus for controlling a mechanical parking lock device of an electric vehicle including an electric motor, the mechanical parking lock device including a parking lock gear rotated with a wheel of the vehicle, a parking lock pawl having a lock position for engagement of the lock pawl with the lock gear to lock the wheel, and an unlock position for releasing the lock pawl from the lock gear, and an engaging member mechanically linked with a shift lever, for engagement of the engaging member with the lock pawl to bring the pawl into the lock position upon operation of the shift lever to a parking position, and for permitting the lock pawl to be moved to the unlock position upon operation of the shift lever from the parking position to another position, the apparatus including a parking release intention determining device for determining an intention of a vehicle operator of operating the shift lever from the parking position to another position, and a parking release motor control device, which is operable upon determination of the operator's intention by the parking release intention determining device, for activating the electric motor so as to reduce a load of engagement between the lock gear and the lock pawl.

A tool holder device including a first and a second member having respectively a projection and a bore which are engageable with each other. The second member has an annular groove which partially defines the bore and is coaxial with the bore. The projection has a through-hole in which are received two engaging members having respective inclined surfaces which are abuttable against with an inclined surface of the annular groove when the two engaging members are moved away from each other upon rotation of a threaded member which engages at least one of the two engaging members. The inclined surfaces of the engaging members and annular groove permit a tight fit between the projection and bore, for removable connection of the first and second members.
