摘要： A worm gear mechanism (44) comprises a worm (70) and a worm wheel (80) meshed with the worm. In the teeth of a hob (90) used for the gear cutting of the worm wheel, at least the addendum surfaces (91c) are formed into arcuate shapes. The radial centers (93) of the arcs of the addendum surfaces are positioned nearer to a center line (WL′) of the hob than a pitch line (94) of the hob. The worm wheel is cut into a gear by the hob. The worm is formed into the same shape as the hob. The recess meshing length (L) of the worm gear mechanism is designed to be greater than the recess meshing length (Llim) of a conventional worm gear mechanism.

摘要： A worm gear mechanism includes a worm connected to an electric motor, and a worm wheel engaged with the worm. In the worm wheel, a tooth flank is formed of a resin material. In the tooth flank, an engagement recess, which is based on a trajectory of a contact point being in contact with a tooth of the worm according to a rotation of the worm, is formed by injection molding, together with the tooth flank, using a mold. The engagement recess includes a plurality of points which are recessed in the direction of a tooth of the tooth flank correspondingly to the trajectory of the contact point with which the most convex portion of the tooth of the worm is in contact. A line connecting the plurality of points interconnects with respect to a tooth width center line of the tooth flank of the worm wheel.

摘要： A vehicle is equipped with a torque sensor configured to detect a torque, and which is disposed on a second transmission path connecting a first rotary electric machine and a first branch point on a first transmission path. When a first switching device is placed in a connected state and a vehicle wheel is driven by an internal combustion engine, a control device causes an inverted phase torque, which is opposite in phase to a detected torque detected by the torque sensor, to be generated in the first rotary electric machine.

摘要： A dual-pinion electric power steering device has: a rack shaft that causes a turnable member to turn; a first pinion shaft to which a steering force from a steering wheel is transmitted; a first rack teeth disposed on the rack shaft and capable of meshing with the first pinion shaft; a second pinion shaft to which a rotational driving force from an assist motor is transmitted; a second rack teeth disposed on the rack shaft and capable of meshing with the second pinion shaft; a first pressing member disposed across the rack shaft from the first pinion shaft and configured to press the rack shaft toward the first pinion shaft; and a second pressing member disposed across the rack shaft from the second pinion shaft and configured to press the rack shaft toward the second pinion shaft. The first pressing member has a lower rigidity than the second pressing member.

摘要： A vehicle is equipped with a torque sensor configured to detect a torque, and which is disposed between an internal combustion engine and a first switching device on a first transmission path. When the first switching device is switched from a disconnected state to a connected state, a control device calculates a torque difference between a target torque of the internal combustion engine corresponding to a specified point on the first transmission path, and a detected torque or the like detected by the torque sensor. Further, the control device generates in a first rotary electric machine or a second rotary electric machine a compensation torque that compensates for the torque difference.
