摘要： A torque cam mechanism comprises first and second cam members disposed relatively rotatably around a common axis and cam balls adapted to fit in first and second cam grooves formed, respectively, in confronting surfaces of the first and second cam members. The depth of the first cam grooves is made larger than the radius of the cam balls, whereas the depth of the second cam grooves is made smaller than the radius of the cam balls, whereby even though a centrifugal force is applied to the cam balls which rotate together with the first and second cam members, the generation of thrust forces for separating the confronting surfaces of the first and second cam members can be suppressed by receiving the centrifugal force so applied to the cam balls by the first cam grooves which are deeper.
摘要翻译：扭矩凸轮机构包括围绕公共轴线相对可旋转地设置的第一和第二凸轮构件，以及适于装配在分别形成在第一和第二凸轮构件的相对表面中的第一和第二凸轮槽中的凸轮球。第一凸轮槽的深度大于凸轮球的半径，而第二凸轮槽的深度小于凸轮球的半径，由此即使将离心力施加到凸轮球，与第一和第二凸轮构件一起旋转，通过接收通过更深的第一凸轮槽施加到凸轮球的离心力，可以抑制用于分离第一和第二凸轮构件的相对表面的推力的产生。

摘要： A four-wheel drive vehicle having a first hydraulic pump operated in operative association with the rotation of front wheels, and a second hydraulic pump operated in operative association with the rotation of rear wheels, such that a difference in rotational speed is produced between the front and rear wheels, a multi-plate clutch is brought into its engaged state by a hydraulic pressure generated by the hydraulic pumps, whereby the mode of the vehicle is shifted into a four-wheel drive mode. A torque cam mechanism is disposed between a clutch piston and clutch plates, so that when the difference in rotational speed is produced between the front and rear wheels, the torque cam mechanism produces an axial thrust force immediately to promptly bring the multi-plate clutch into its engaged state. The engagement of the multi-plate clutch is achieved with a sufficient engagement force by the hydraulic pressure thereafter produced by the hydraulic pump.

摘要： An electromagnetic clutch having a solenoid coil (80), a coil housing (81) disposed surrounding the solenoid coil (80), an armature plate (82) disposed facing the side of the coil housing, and a clutch mechanism. The current flowing to the solenoid coil (80) is controlled so as to control the clamping of the armature plate (82) to the coil housing (81), and the clamping force acting on the armature plate is used to control the engagement of the clutch mechanism. There is also a lubricating oil supply channel (63) for supplying lubricating oil from the inside in the radial direction into a gap between the coil housing and the armature plate, and oil reservoir holding lubricating oil to be supplied into the gap is formed around the inner periphery of the portion where the coil housing faces the armature plate.

摘要： Provided is a driving force control device for a four-wheel-drive vehicle that can evade an occurrence of excessive understeer and oversteer in situations unintended by the driver, by appropriately controlling driving forces to be distributed to sub-drive wheels. The driving force distribution device of the four-wheeled vehicle controls driving force to be distributed to the rear wheels (Wr, Wr) by the clutch (10) for front-and-rear torque distribution so that the wheels (Wf, Wf) are main drive wheels and the rear wheels (Wr, Wr) are sub-drive wheels. The driving force distribution device is adapted to perform control to restrict the upper limit of the four-wheel drive torque based upon an estimated driving force and steering angle of the vehicle, when calculating four-wheel drive torque to be distributed to the rear wheels (Wr, Wr) by the driving force distribution device (10).

摘要： Backward movement of a heavy motorcycle is assisted by a starter motor for cranking an engine of the motorcycle. A backward drive control system includes a pulse width modulation circuit for supplying operating current to the starter motor in a controlled manner and a device for estimating operating temperature of the starter motor based on the current supplied to the starter motor. When the estimated temperature reaches a predetermined maximum temperature, the operation of the starter motor is compulsorily stopped and prohibited for a certain period or until the starter motor is cooled down to a certain temperature level. Overheating of the starter motor is effectively prevented without using a temperature sensor for measuring the operating temperature.Moreover, chattering of the starter motor does not occur because its operation is prohibited for a certain period after the starter motor is once compulsorily stopped.
