QM 7 E K4/figs United States Patent O 3,190,237 RAILWAY TRUCK Thomas A. Hurtner, Albany, N.Y., assignor to Adirondack Steel Casting Co., Watervliet, N.Y. Filed Feb. 12, 1962, Ser. No. 172,412 4 Claims. (Cl. 10S-182) This invention relates to animproved truck adapted to be associated with `railway cars. The truck of this in-y vention Vis particularly characterizedby its light weight, durability, economy of manufacture and smooth and silent operation.
A great deal of interest-presently exists with regard to the provision of economical and eiicient structures forrailway cars. As metropolitan areas expand, rapid transit systems are being developed, expanded and modernized and it is, of course, desirable to accomplish this with the greatest possible eiciency.
Apart from the expense, severe problems exist in railway transportation relating tothe smoothness of the ride and to the noise produced. The design of the trucks for the cars plays a large role in determining smoothness and quietncss. With many truck designs, it is necessary, in order to avoidV irritating noise, to resort to elaborate insulation or other modications in the car design.V
An additional objection to most truck designs resides in the massiveness of the components thereof and the necessity for various elements which add to the weight of the trucks. Obviously any weight saving in railroad cars is desirable, since a corresponding decrease in the energy necessary to start, stop and transport the cars will result. These energy considerations are particularly critical in rapid transit systems, since a great many stops are made for a given distance of operation;
Itis thus apparent that railway trucks which are economical from the standpoint of production costs and maintenance are of considerable importance to the industry. Trucks which combine with these characteristics smooth, quiet and efticient operation and which are also light in weight are particularly desirable.
It is, accordingly, an object of this invention to provide railway trucks which can be economically manufactured and maintained and which are characterized by light Weight as well as smooth, quiet operation.
`Otherobjects and advantages of this invention will appear hereinafter, and for purposes of illustration, but not of limitation, specific embodiments of this invention are shown in the accompanying drawings in which- FIGURE 1 is a side elevation, partly cut away, of a railway truck characterized by the features of this invention;
FIGURE 2 is a plan view of the railway truck shown in FIGURE l;
FIGURE 3 is a near elevation, partly cut away, of the `railway truck shown in FIGURE 1;
of FIGURE 2; and
FIGURE 5 is a detail view taken about the line 5-5 of FIGURE 1.
The railway truck of this invention comprises a frame portion having journal boxeslocated at the corners of the frame portion for supporting the axles and wheels for the truck. The journal boxes employed comprise an arm portion having means for pivotallyj connecting the boxes to the truck frame. Upstanding portions are also integrally formed in the boxes and resilient members are interposed between these upstanding portions and the truck frame. These resilient members are thus able to react to forces resulting from relative movement between the truck frame and the journal boxes.
3,190,237 Patented June 22, 1965 FPice The truck design of this invention also preferably includes a swivel connection located centrally of the frame for engagement with a railway car whereby Vthe truck swivels with respect to the car in a well known fashion. Spaced laterally of this swivel connection, there are provided support means for locating spring members. The springs are adapt-ed to engage the under side of the railway car and are designed to carry substantially all the weight of the car. Bearing means which are located between the car and the spring means are adapted to be linked to the truck frame in a manner such that improved stability of the car is provided. j
Brake means are adapted to be located on' thetruck frame at the sides of the frame between the wheels on each side and below the spring supporting means. Pistons extend from either end of the brake means and the brake shoes connected to the pistonsengage the wheels in a manner such that operation of the brake means results in opposing forces being transmitted to the respective wheels on a given side of the frame.
The accompanying drawings will provide a more detailed illustration of the subject matter of this invention. The railway truck, generally designated by the numeral 10, is shown in FIGURE 1 as it would appear relative to a car body, designated by the line 12, and a railway, designated by the line 14.
The truck includes a frame 16 having interconnecting transoms 1S. Pivotally secured to the frame 16 at the point 20 are the arms 22 which are integrally formed in journal boxes 24. The journal boxes are provided for supporting axles 26 carrying wheels 28. Y
A vertically extending lug 30 is formed in each journal box 24, and these lugs terminate in faces 32. Resilient inserts 34, which maybe bonded rubber sandwiches, are interposed between the faces 32 and faces 36 formed in the frame 16. By reason of the pivotal connection between the boxes 24 and the frame 16, and due to the resilient character of the inserts 34, the journal boxes and frame can bemoved relative to each other and the inserts will take up therstresses resulting from this movement.
A pair yof supporting seats 38 extends laterally from the Y frame d6 and is provide-d for supporting bellows-ty=pe alr springs 40. The air springs are each connected to an upper member 42 having a bearing surface 44 thereon. These bearing surfaces 44 are adapted to contact the underside tof the car body and serve to support substantial- 16. Lifting lugs 50 secured to the car body are adapted to tit over projections 52 formed in the link brackets 48 'to permit interengagement of the truck and car body.
Secured to the sides of the frame beneath the supporting seats V38 is a pair of airbrake units 54. These units include pistons 56 which terminate in brake shoes 58. Links 59 are pivotally secured at one end to the frame 16 and at the other end to the brake shoes 58, and these links provide vertical support for the pistons and brake shoes. A snubber 6l) is located between members 42 and supporting seats 38. i
The car body is adapted to be provided with a swivel connection withV the truck at the point 62. Therdescribed apparatus may also be provided with a drive means such as may be employed in self-powered rapid transit units. The drive means illustrated includes a drive shaft 64 connected to a power unit (not shown).
forceto a similar gear drive unit 70. The specic ar-V f rangement of the shaft 72 and transorns 1S is shown in detail in FIGURE 4.
The driving mechanism Yillustrated is also providedA with conventional torque arms76'which are connected at one end to the gear boxes and.l at the otherl'end to'brackets 78 it will be apparent that the specific drive" means employed is not critical. It will also be apparent that a drive means can be excluded, as is the case in many truck applications.
FIGURE illustrates in detail the pivotal connection between the arm 22 of a journal housing 24 and the frame 16. This connection includes-a pin 8l)V extending through Yformed in the frame 16. In considering the truck design, Y

openings in the arm 22. g `Arresilient bushing'82 is located within an opening in frame 16 and the pin'St) is located within the bushing. Since the uique design of this truck `Yprovides for pivotal movement between the journalrbox 24 and the frame 16, theconnection between these members is vof critical importance.` It is necessary, in addition to insuring against fracture in pthis joint, to provide for a smooth, silent operation. yA Clevite Silentbloc bushingis particularly suitable for this arrangement. Y A resilient*Y bushing of this design permits silent pivotal movement between the members, while at the same time providing allowance for torsional stresses tending 4tebend the arm 2,4 transversely VVof the frame 16K. v f Y In the described railway truck design, the vertical loads are carried by the air coil spring combination supportedV by the one piece frame 16. By locating the springsroutwardly of the truck in the manner shown, maximum lateral -stability `can be achieved, and a substantially con-V stant car body height, independent of passenger load, -wili result.
the provision'vof the links 46 has also been'found to enhance the stability of the system; The locationY of these links establishes the desired vertical position ot the spring The journal housings 24 are preferably provided with self-aligning spherical roller bearings.fThe provision of these bearings in the one piece journal housings aidsV in providing a smooth operation for the trucks. Y
The vdirect springing action aiorded by ythe provision of the resilient inserts 34` provides greater rigidity in the railway cars. Bondedirubber sandwiches are particularly suitable for use as the inserts, since .they will Vstand up under shear and compression Yforces.V The four pivoted `journal housing assemblies allow for the desired'lateral and vertical misalignment Iof* ythe axle assemblies which is required `for equalization ofthe system.4 This arrangement eliminates the usual pedestal legs required Yforr'guidance of Y journal boxes, and fortransmitting aeleration, deceleration and lateral forces occurringfbetween the axle assenti-- bly'and the truclf;V frame. VThe usual wear and noise en-V countered between the pedestals and journal box wear 'plates are accordingly eliminated andvlateral cushioning of the axle assemblies also reduces wear in the wheel flanges. l f
Furthermore, the journal and equalizer springs are elimi- Y nated` with this design yand a bolster is not required, since vthe center pin does not carry vertical loads. i
Various drive arrangements caribe employed with the described trucksI includingthe use of one gear drive lper axle, with car body. mounted traction motorsV or torque converters.
Parallel `mounted traction motors with gear drives mounted to the truck frame, or right angle mounted k"traction motors with gear drives mounted to theV truck,` Vframe are also conter'nplated.` As previously indicated,
however, the inventive aspects described are not dependent upon Va particular drive andare equallyvaluable the provision of any drive means. I
The particular brake design illustrated provides distinct without advantages in the railyway truck. Since the brake shoes l are each directed to the inside of the wheels, operation of the brake results in the production of equal but opposite forces', These forces ofsetgeach other and minimize transl mission of stress to the truck frame. r Y
It will be apparent that Athere has been described a railway truck characterized by relatively simple construction whereby equipment cost can 4be substantially reduced.
isfoffparticular importance from a cost and maintenance standpoint. Furthermore,f-the` design described enables eliminationrof various equipment conventionally employed i. Y and, therefore, the weight as well as the cost of the equip-` t ment is reduced.'Y The design also-is characterizedby smooth operation and a resulting decrease in the `transl mission of vibrations. Steel-to-steel contactbetween moving parts is also substantially eliminated'and, therefore, al J major source of noise is absent in the design of this inven;y
tion.
ous other applications are contemplated. Y
It will be .understood'thatvarious, modications may. tbe made inthe above described railway truck which pro`-` l vide the characteristics of this inventionwithout departing .i fromV the'spirit thereof, particularly as defined. in the folbk t lowing claims.
