摘要： This invention is concerning a driving torque distribution method for front-and-rear-wheel-independent-drive-type electric vehicles (FRID EVs) in which it is possible to get stable steering on a low friction coefficient road surface. This method is characterized by distributing driving torque to the left and right wheels of the front and rear wheels, considering not only load movement of the longitudinal direction but also load movement of the lateral direction which is generated at cornering. The load movements are estimated by detecting components of the 3-axis directions, i.e., longitudinal and lateral accelerations and yaw rate, and the steering angle and friction coefficient of the road surface. The effectiveness of the proposed driving torque distribution method was verified using simulators equivalent to the prototype FRID EV simulated with Matlab/Simulink and CarSim software. This method is expected to be indispensable to improving running performance of FRID EVs.

摘要： In the state where a tire valve cap body has been fixedly screwed onto a valve mouthpiece, a top cover is pushed to open a tire valve, allowing introduction of a tire air pressure. A piston is slidably incorporated in a cylinder chamber defined within the top cover and is urged by a return spring. Upon the introduction of the tire air pressure, the piston is displaced to a position at which the biasing force of the return spring balances with the force of the introduced air pressure. An indication mechanism is provided to indicate, through an indication window formed in a cylinder member, a position of the piston member displaced by the tire air pressure introduced, thereby indicating a measurement value of the tire air pressure.

摘要： An electromagnetic actuator is provided at the outer periphery of and out of contact with a casing of a transmission joint for transmitting torque between two shafts. The electromagnetic actuator produces an electromagnetic field within the joint main body when an exciting current is supplied to a solenoid coil of the actuator. A movable magnetic ring is provided in the casing so as to be movable in the axial direction. The ring is moved in the axial direction by receiving an electromagnetic force induced by the field produced by the electromagnetic actuator. A relief valve connected to the ring is moved over an orifice of a pump, and a spring biasing the relief valve is compressed due to such movement, thereby establishing a relief pressure. When a rotational difference, created by the tires of the vehicle, occurs between the shafts of the joint, and an oil pressure of the pump rises while the joint is in a locked state in which the relief valve closes the orifice, the relief valve is opened, thereby limiting torque transmission to a predetermined value based on the relief pressure. Further, by opening a free valve also associated with the pump, the torque transmitting function of the pump rendered inoperative and a free state (2WD) occurs in which there is no torque transmission. A detecting coil is provided in parallel with the solenoid coil. After the solenoid coil is driven, the current value is changed. A change in magnetic flux according to a magnetic resistance in association with the movement of the movable magnetic ring occurs in the detecting coil. The position of the movable magnetic ring is discriminated from a voltage which is generated in the detecting coil in this instance.

摘要： Provided is a transmission which eliminates torque loss during gear shift and with which the processing of components can be simplified. An axial force is generated in a protrusion by means of a first portion during gear shift from a low gear to a high gear, and when a low-speed transmission gear and a clutch ring separate from each other, a high speed transmission gear and the clutch ring interlock. Since relative movement of the protrusion in a neutral direction is suppressed by means of a first retaining portion during coasting, gear disengagement whereby the transmission gears and the clutch ring separate from each other can be suppressed. Since the first retaining portion can be formed in a first wall when providing a groove portion, an increase in the component processing workload can be suppressed.

摘要： A power transmitting device makes a motor in a hybrid vehicle be smaller and lighter, prevents internal resistance and inertia of the generator motor from becoming driving resistance, and can effectively utilize energy. Via a first clutch, power is transmitted from an input shaft to a transmission shaft but power transmission vice versa is blocked, and power transmission from the input shaft to the transmission shaft can be blocked. Via a second clutch, power is transmitted from the transmission shaft to the input shaft, while power transmission vice versa is blocked. Thus, when driving using only the power of the engine, power transmission from the input shaft to the transmission shaft is blocked, thereby preventing transmission of power to the generator motor. Consequently, the generator motor can be made smaller and lighter, and energy losses can be prevented.
