摘要： Since a speed reducer includes: a brake disk that is fixed to a rotationl shaft of a vehicle; permanent magnets that are disposed not only oppositely relative to a principal surface of the brake disk but also circumferentially in such a manner that each magnet is magnetized in reverse polarity to adjacent ones; a rotational member that retains the permanent magnets, has a switch brake disk, and is rotatably supported by the rotational shaft; a switch brake caliper that has brake pads sandwiching the switch brake disk therebetween, and is fixed to an irrotaional portion of the vehicle; and an electric linear actuator of a planetary roller mechanism that causes the brake pads to be linearly driven by converting rotational motion of the electric motor into linear motion, the speed reducer can realize a reduction in size, and thus can be installed even in a small- to mid-size vehicle not especially equipped with a compressed air tank or the like.

The electric vehicle includes the motor units; a torque command unit (23) that outputs torque command values to the motor units; a torque difference occurrence determiner (31) that determines that a difference has occurred between actual driving forces TL, TR of the respective drive wheels (2) even when the torque command unit applies the same torque command values TL*, TR* to the motor units; and a driving force difference reducer (32) that, if the determiner determines that a driving force difference not less than a set value has occurred between the drive wheels, causes control of reducing the driving force difference to be performed during travelling.

摘要： An object is to make it possible to stably transmit torque of the rotary shaft to the respective planetary rollers without applying a preload to the planetary rollers with a negative gap between the radially outer surface of the rotary shaft and the radially inner surface of the outer ring member.
Planetary rollers 7 rotatably supported on their radially inner surfaces by respective support pins 6b are radially inwardly biased by radially compressible ring springs 18 enveloping the support pins 6b, thereby biasing and pressing the respective planetary rollers 7 against the radially outer surface of a rotary shaft 4. Thus, it is possible to stably transmit torque of the rotary shaft 4 to the respective planetary rollers 7 without applying a preload to the planetary rollers 7 with a negative gap between the radially outer surface of the rotary shaft 4 and the radially inner surface of the outer ring member 5.
