    • A method of controlling the mode of driving an electric vehicle so that the electric vehicle is accelerated at a maximum acceleration and is decelerated at a maximum deceleration. The mode of variation of the running speed of the electric vehicle is estimated on the basis of the variation of the running speed of the electric vehicle calculated from the revolving speeds of the axles of the electric vehicle detected by revolving speed detectors associated with the axles, respectively. The axles are controlled for minute idle rotation or minute slip on the basis of the estimated mode of variation of the running speed of the electric vehicle to produce a maximum effective adhesion between the wheels attached to the axles and the rail so that the acceleration of the electric vehicle at a maximum acceleration and the deceleration of the same at a maximum deceleration are achieved. The torque of the axle carrying the greatest axle load among the driving axles of the electric vehicle is reduced intermittently or continuously so that the wheel attached to this axle is brought into steady rolling contact with the rail to calculate the estimated mode of variation of the running speed on the basis of a time interval between two successive torque reducing operations by means of a microprocessor or the like. Thus, the mode of driving an electric vehicle can be accurately controlled to produce a maximum effective adhesion through calculation based on the revolving speed of the axle.

    • The tooth shape at around the pitch circle of the outer tooth gear of the pinion to be connected to the prime mover or driven shaft has a tooth surface which is in axial direction at around the central portion of the tooth width and which contacts at around the tooth width end at the allowable displacement angle and the backlash is made small and the outer tooth gear of the pinion is crowned in to an exponential function curve. The precession vibration and the torsional vibration at a high speed rotation can be suppressed because of the small backlash. The crowning curve is exponential function which causes the contacting point to move toward the tooth width end as the displacement increases and the radius of curvature becomes larger as the point on the curve approaches to the tooth width end, so that even when the contacting gear number decreases when displaced, the increase in the contacting stress is suppressed and a larger power can be transmitted as compared to the conventional design.
