Definitions

  • My invention relates to locomotive or car trucks and particularly to trucks for electrically propelled locomotives or cars and has for its object to provide a novel and improved mounting for the motors of such trucks which will reduce the dead load on the axles.
  • it is customary to mount one side of the m0- tors directly upon the axles and resiliently support the other side of the motor from a transom or truck frame. This reduces to some extent the dead weight caused by the mot-or on the transom or truck frame but leaves a portion of the ⁇ weight of the motor asl dead weight on they axles.
  • invention consists in providing improved resilient means between the axles and the motors to reduce to a minimum the dead weight upon the axles.
  • Vinvention further consists in using the electric motors as a part of the mechanicalV portion of the truck, .supporting them between theV axles and transom, the transom being supported by equalizer-s which in turn are supported by the motor frames so that the whole truck structure including the motors is carried by the lresilient means 'interposed between the motors and the axles.
  • the supports of the motors on the axles are used as the main journals, so that no outside journal boxes or any frame are required and at the lsame time by reason of my improvement t-he dead weight upon the axles will be reduced to a minimum.
  • FIG. 1 is a side elevation of a truck embodying my invention
  • Fig. 2 is a plan view of the truck shown in Fig. 1
  • F ig. 3 is an end elevation, partly in section, of a truck embodying my serial no. 664,970.
  • the motors 7 have a nose 16 somewhat similar to the ordinary nose on a railway motor, only larger, which fits intoy a recess 17 in the transom 8 so as to prevent up and down or sidewise movement of the motor 7 with respect tothe/transom. Part of the weight of each motor is thus carried by the transom 8.' The balance of the weight ofthe motor is carried by the axle 5. Mounted upon the axles 5 are the journal boxes 18 having bearings 19. Projecting from the framelof motor7 ⁇ are overhanging jaws 2() whichengage the journal box 18 to secure thc-motor to the axle 5.
  • journal box 18 Interposed between the journal box 18 and the motor frameare a plurality of sets lof leaf springs 21 aligned with each otherand with the axle and having their ends supported in pockets Von the top ofthe journal box 18 and supporting part of the weight ofthe motor 7 at their centers.
  • This arrangement by reason of the resiliency of the leaf springs 21 will reduce to a considerable extent the dead load upon theaxles 5.
  • I provide an oil well 22 above the j ournal boxes 18 having outlets 23 which discharge oil over the springs 21 and into the journalbox 18. I thereby secure proper lubrication of the springs 21 and the bearings 19 from a common source.
  • the outer ends of the transom 8 form a support for the brake rigging and .air cylinders 28, the brake levers 29 being pivotally connected to the ends of the transom and inline with the. wheels G.
  • the transom has a cavity extending from thecenter plate lopening 30 to outlets 3l formed in the side of the transom. lThese out-lets 3l areprovided with 'sliding sleeves 32 which are biased in an .extended position and engage the frame of the motors 7.
  • 4The. motors 7 have openings or air inlets adjacent the sliding sleeves 32 to permit air to bev forced into the motors through the center plate opening 30 and the transom 8 for the purpose of .cooling them.
  • the sliding sleeves 32f have alinished surface which engages a similar finished surface surrounding the air inlet of the motors 7 and this in conjunctionewith the biasing means provides a tight joint be tween the transom and the motor frame for the circulation of the cooling'air and at the same time yper-mits relative displacement of the openings.
  • An axle mounting for railway motors comprising a motor,'an axle, wheels on said axle, a journal box on said axle, and a plurality ofsets of leaf springs interposed between said motor andsaid journal box for supporting said motor, said sets of springs being aligned with each other and with said axle.
  • An axle mounting for railway motors comprising a motor, an axle, wheels on said axle, a journal box on said ⁇ axle between said wheels, jaws formed on said motor engaging said journal box, and resilient means interposed between said journal box and said motor for supporting said motor comprising a plurality of sets of leaf springs having their ends supported on -said journal box and supporting said motor at. their centers, saidfsets of springs being ⁇ aligned with each other and with said axle.
