Cyclopedia of applied electricity : a general reference work on direct-current generators and motors, storage batteries, electrochemistry, welding, electric wiring, meters, electric lighting, electric railways, power stations, switchboards, power transmission, alternating-current machinery, telegraphy, etc. . traction truck the center of support is shifted from thecenter to a point as nearly over the motor axle as possible, as shownin .Fig. 15. The two pairs of wheels are of different diameters, 113 18 ELECTRIC RAILWAYS the driving wheels being of as large diameter as the room underthe body permits. The others are pony wheels which follow thecurvature of the track with great precision. The motor is outsidehung from the main axle as in the case of the short wheel-basetruck. In the type of truck shown in the figure, the bolster ismounted on leaf springs hung from the side bar by links, this beingnecessary in order to allow space for the brake rigging between thewheels. The essential features of the maximum traction truck arethe same as in those described earlier. In the side elevation of acar body in Fig. 8, the wheels of a maximum traction truck areshown.
