摘要： The power transmission mechanism reliably starts an internal combustion engine that is stopped during travel of a vehicle. While the internal combustion engine is stopped and the internal combustion engine and the transmission are disengaged by the main clutch, it is determined whether the mode is the EV travel mode, corresponding to the driving mode by the electric motor. In the case of the motor driving mode, and if the vehicle speed is less than a predetermined value, the engine is started in a neutral mode. If the vehicle speed is higher than a predetermined value, the engine is started in a standby mode. When starting in the standby mode, a gear set is selected based on the vehicle speed, and the input shaft and the output shaft are engaged.

摘要： A laser-emitting head (12) is placed in a cavity (6) of an aluminum hollow and profile material (3), the material being of a desired shape in cross section and having an inner peripheral wall. A laser beam of an energy level capable of cutting the material is irradiated from the cavity onto the inner peripheral wall while the head is being rotated along the wall in a circular direction. The hollow and profile material (3) can be sliced in this manner to produce knuckles (1) as one of automobile parts, even if it is of a comparatively large size adapted for production of larger knuckles.

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 driving force distributing device is provided for distributing a driving force of an engine to the left and right wheels of a vehicle by bringing a pair of hydraulic clutches into and out of their engaged states. The distributing device includes a hydraulic pump mounted within a casing thereof and driven through gears by a half shaft connected to one of the wheels. An oil passage interconnects the hydraulic pump and the hydraulic clutches, the oil passage being defined in a casing. A valve block is coupled to an upper surface of the casing. Thus, the oil passages interconnecting the hydraulic pump and the hydraulic clutches of the driving force distributing device can be compactly formed.

摘要： A feed-forward control section controls, in a feed-forward manner, left and right hydraulic clutches C.sub.L and C.sub.R of a driving force distributing device by presuming such a driving force distribution amount .DELTA.T that a yaw rate corresponding to a turning state of a vehicle is obtained, based on an engine torque, an engine revolution-number, a vehicle speed, a steering angle and a lateral acceleration. On the other hand, a feedback control section calculates a deviation between a reference yaw rate calculated from the vehicle speed and the lateral acceleration and an actual yaw rate detected by a yaw rate sensor, and corrects the driving force distribution amount .DELTA.T calculating in the driving force distributing device in order to converge the deviation into zero. Therefore, even if the driving force distribution amount becomes excessive due to the feed-forward control to produce an over-steering tendency in the vehicle, this over-steering tendency can be eliminated by the feedback control to stabilize the behavior of the vehicle.

摘要： A power transmitting system of a four-wheel drive vehicle having primary driven wheels driven directly by a prime mover, and subsidiary driven wheels driven through a hydraulic clutch. The power transmitting system comprises a first hydraulic pump driven in operative association with the primary driven wheels and a second hydraulic pump driven in operative association with the subsidiary driven wheels. Each hydraulic pump has a pair of ports which serve as an intake and a discharge with the functions of such ports being reversed between forward and backward movement of the vehicle. A first oil passage connects the intake port of one pump with the discharge of the other pump and a second oil passage connects the discharge of the one pump with the intake of the other pump. Third and fourth oil passages connect the first and second oil passages, respectively, with a working hydraulic pressure chamber in the hydraulic clutch. A one-way valve is provided in each of the third and fourth oil passages for permitting only a flow of oil toward the working hydraulic pressure chamber. The reversal of vehicle movement and direction of oil discharged from each of the hydraulic pumps provided in the power transmitting system of the four-wheel drive vehicle is compensated for by a simple structure of oil passages and one-way valves.
