<p>PURPOSE:To switch several vehicle operation status only by driving the rotation of a uniaxial motor cam shaft performing changeover operation. CONSTITUTION:When vehicles advance forward and perform power running in the tooth track section, breakers 14 and 15 make contact and a cam shaft is switched into (3) RF F position. Contactors F, P, Q, T, and M including other ones close. Both moters 1 and 3 operate as a direct winding motor. For the power running at the adhesion section, the cam shaft is switched into (4) AD F position and the contactors F, P, M, N, and S close. A tooth track motor armature 3 is connected in parallel to an adhesion motor armature 1 through an internal resistance drop compensating resistor 12. The magnetic field windings 2 and 4 of both the motors are in series by a contactor S and connected to the armature, thereby constituting a synchronous circuit. A generated braking circuit is formed by switching the cam shaft into (5) DB F position while closing the contactors D, F, M, and S and letting a breaker 13 to make contact.</p> |
