The electric motor with a reverse input cutoff clutch has an output shaft. The output shaft is configured by connecting a first shaft and a second shaft that are coaxially arranged with each other via the reverse input cutoff clutch. The second shaft is rotatably supported to a housing by one radial bearing. The reverse input cutoff clutch has a function that, when rotational torque is inputted to the first shaft, transmits the rotational torque inputted to the first shaft to the second shaft, and when rotational torque is reversely inputted to the second shaft, completely cuts off the rotational torque reversely inputted to the second shaft, and does not transmit the rotational torque to the first shaft, or transmits a part of the rotational torque to the first shaft, and cuts off the remaining part.

Electric motor with reverse input cutoff clutch

A reverse input blocking clutch includes an input member, an output member, a pressed member, and an engaging member. When a rotational torque is inputted to the input member, the engaging member moves in a direction away from a pressed surface of the pressed member due to engagement with the input member, and transmits the rotational torque inputted to the input member to the output member due to engagement with the output member; and when rotational torque is reversely inputted to the output member, moves in the direction closer to the pressed surface based on engagement with the output member, and by being pressed against the pressed surface does not transmit the rotational torque reversely inputted to the output member to the input member, or transmits only part thereof to the input member due to engagement with the input member.

Reverse input blocking clutch and actuator

The reverse input shutoff clutch includes: an input member, an output member coaxially arranged with the input member, a pressed member having a pressed surface, and an engaging element. The engaging element, when rotational torque is inputted to the input member, moves in a direction away from the pressed surface due to engagement with the input member and transmits the rotational torque to the output member, and when rotational torque is reversely inputted to the output member, moves in a direction toward the pressed surface due to engagement with the output member, and prevents or suppresses relative rotation between the output member and the pressed member.

Reverse input shutoff clutch, electric valve timing adjustment device, variable compression ratio device, and electric power steering device

An electric vehicle driving device includes a first motor, a second motor, a transmission device to which power of at least one of the first motor and the second motor is transmitted, and an output member that rotates with power output from the transmission device. A rotation axis of the first motor, a rotation axis of the second motor, and a rotation axis of the transmission device are arranged in parallel to a rotation axis of the output member. When seen from an axial direction parallel to the rotation axis of the output member, the rotation axis of the first motor is located on one side of a straight line passing through the rotation axis of the output member and the rotation axis of the transmission device and the rotation axis of the second motor is located on the other side of the straight line.

Fletching wear caused by elastic deformation in the axial direction of an input-side diskdue to thrust force of a pressure device is prevented. A female-spline sectionformed around the middle section in the axial direction of the inner-circumferential surface of a center holein the input-side diskand a male-spline sectionformed around the outer-circumferential surface of one end section in the axial direction of an input rotating shaftengage with a spline engagement. A disk-side fitting surface sectionformed around a portion of the inner-circumferential surface of the center holein the input-side diskthat is adjacent to the other end side of the female-spline sectionand a shaft-side fitting surface sectionformed around a portion of the outer-circumferential surface of the input rotating shaftthat is adjacent to the other end side of the male spline sectionare fitted together with an interference fit.

Toroidal continuously variable transmission

Construction of a toroidal continuously-variable transmission is achieved that simplifies the manufacture of parts, management of parts and assembly work, is able to easily reduce costs, stabilizes speed change operations, and is processed easily. An outer ringof a thrust rolling bearing is supported so as to be able to pivotally displace by engaging a concave sectionthat is provided on the outside surface of the outer ringwith a cylindrical convex surfaceof a support beamof a trunnion. Displacement of the outer ringin the axial direction of the support beamis limited by engaging a concave groovethat is formed around the inside surface of the concave sectionin the circumferential direction around the support beamwith a protrusionthat is formed around the outer-circumferential surface of the support beam

Toroidal continuously-variable transmission

A continuously variable transmission apparatus includes a toroidal continuously variable transmission, a planetary gear transmission and a clutch apparatus that connects the toroidal continuously variable transmission and the planetary gear transmission. The clutch apparatus includes: a low speed clutch a high speed clutch and a controller. The controller controls the transmission ratio of the toroidal continuously variable transmission so that rotational speeds of members connected via the clutch apparatus equals with each other, and then disengages the one of the low speed clutch and the high speed clutch after engaging the other, whereby an instance of simultaneously transmitting the power by the two clutches is set during a time period until disconnecting the other clutch after starting to transmit the power by the one clutch.

Continuously variable transmission apparatus

A continuously variable transmission apparatus coupled to a drive source has an input shaft, an output shaft, a toroidal-type continuously variable transmission having a pair of input side disks an output side disk, a trunnion, a support shaft and a power roller, and the planetary gear mechanism having a sun gear, a ring gear, a carrier and a planetary gear, wherein a plurality of projections are projected from the one input side disk and provided at positions closer to the outside diameter than to the diameter of a pitch circle of a traction section being close to the outermost diameter of the input side disk, a plurality of engagement sections formed in the carrier, and transmission of power between the carrier and the one input side disk is carried out by coupling the plurality of projections with the plurality of engagement sections.
