<p>PURPOSE:To control driving force on the start of a vehicle easily by mounting a disk consisting of a magnetic substance turned together with an output shaft and an armature, to which the disk is loosely fitted and which is fixed to a car body. CONSTITUTION:A disk 1 made of a magnetic substance is fastened to the left and right output shafts of a wheel so that the peripheral section of the disk 1 is loosely fitted to an opening section in a U-shaped armature 3 fixed to a car body. A coil 3 is wound on the armature 3, and exciting currents are controlled by a transistor Tr in a coil 4. A mean-value arithmetic circuit 7 arithmetically operates the mean value of the speed omega3, omega4 of left and right coupled driving wheels, and an arithmetic circuit 8 arithmetically operates reference speed VR2 on the basis of the mean value. A comparator 9 turns the transistor Tr ON when driving-wheel speed omega1 or omega2 selected by a selecting circuit 6 exceeds reference speed VR, and works braking force to a shaft.</p> |
