    Abstract: An improved seal (10) for use in a universal joint (11) having an elastic seal ring (23) compressed between a pair of right circularly cylindrical sleeves (24, 25). The seal ring is bonded to the sleeves. The sleeves are adapted to have press-fitted relationship with association portions of the universal joint, such as the journal trunnion (12) and the bearing retainer (14). In one form, the elongated extent of the sleeves is parallel to the axis (15) of the journal trunnion (12) and in a modified form, the sleeves (124, 125) extend perpendicularly thereto. In each form, a portion of one of the sleeves is disposed adjacent the inner end of the needle bearings (22, 122) so as to limit axial movement thereof. The sleeves are bonded to the seal ring so as to preclude sliding movement therebetween while yet permitting limited axial play in the universal joint thereby to provide long troublefree life of the seal.

    Abstract: In many designs, a tire (14) of a wheel (10) is inadequately restrained with respect to a tire supporting rim assembly (12) of the wheel. Movement of the tire (14) with respect to the rim assembly (12) results in a wastage of energy. In the present invention a wheel assembly (10) has a rim assembly (12) and a tire (14) mounted on the rim assembly (12). The rim assembly (12) has an annular elastic element (22) affixed thereto for increasing the coefficient of friction between the rim assembly (12) and the tire (14).

    Abstract: A tire cooling system (10) for a vehicle having a wheel (12) with a tire (14) mounted on a rim (16). A heat transfer device (22) is positioned in a central cavity (18) defined by said rim (16) and tire (14). A first fluid (20) is contained in said central cavity (18) while a second fluid (25) is circulated through said heat transfer device (22), said second fluid (25) being in fluid isolation from said first fluid (20). Said second fluid (25) is circulated through a rotating wheel seal (28) to a heat exchanger (38) and back to said heat transfer device (22). Use of an intermediate heat exchanger, such as said heat transfer device (22), permits use of oil as said second fluid (25) permitting leakage from said rotating wheel seals (28) to be contained by and made up from said final drive sump (42). Oil has, of course, a deleterious affect on rubber. Through use of oil in an isolated cooling loop, relatively simple liquid cooling with an external heat exchanger (38) is achieved.

    Abstract: Appareil d'etancheite (16) en materiau elastomere qui comprend une partie interne annulaire terminale (36) qui peut etre attachee a un premier organe (12), une partie (38) annulaire terminale qui peut etre attachee a un second organe (14), et une partie annulaire flexible (40) pourvue de spires qui est disposee entre les parties internes (36) et externes (38) terminales et presente un bord interne (46) et un bord externe (48) qui sont respectivement lies a ces parties. L'epaisseur de la partie flexible en spirale (40) decroit depuis le bord interne (46) relativement epais vers le bord externe (48) relativement fin proportionnellement a une distance radiale (H) depuis le bord interne (46) vers la partie flexible (40). Une spire interne (42) et une spire externe (44) concentriques constituent la partie flexible (40) et presentent respectivement un rayon de courbure relativement petit R1 et relativement grand R2. Lorsque les parties terminales internes (36) et externes (38) sont animees mouvement de va-et-vient par rapport au premier organe (12) et au second organe (14) le long d'un axe longitudinal (16a), la structure conique, et spiralee de l'appareil d'etancheite (16) presente une duree de vie prolongee en raison de l'egalisation des deformations maximum qui y sont produites.

    Abstract: Un dispositif de detente de galets tendeurs (10) est utilise pour des vehicules du type a chenilles. Le dispositif de detente de galets tendeurs (10) protege un systeme a chenilles de roulement (11) contre les degats provoques par des corps etrangers, tels qu'une roche ou pierre emprisonnee entre un assemblage a maillons de chaine sans fin (28) et un element de support de chaine (20, 22, 24, 26) du systeme a chenilles de roulement (11). Un maillon de galets tendeurs (30) est connecte de maniere pivotante a une structure de chenille (12) du systeme de chenilles a roulement (11) et un galet tendeur arriere detendable (24) est positionne en rotation sur un moyeu de galets tendeurs (54) lui-meme relie de maniere pivotante a ce maillon de galets tendeurs (30). Une augmentation de la tension de cet assemblage a maillons de chaine sans fin (28) fait tourner ce moyeu de galets tendeurs (54) en l'eloignant de l'assemblage a maillon de chaine sans fin (28) diminuant ainsi la longueur de la course de la chenille et, par consequent, la tension. A cette rotation resiste elastiquement un patin de detente (66) monte entre le moyeu de galets tendeurs (54) et le maillon de galets tendeurs (30). Un maillon de traction (68) empeche toute detente jusqu'a une tension preselectionnee de l'assemblage a maillon de chaine sans fin (28).

    Abstract: Les liaisons de l'art anterieur servant a transmettre des signaux au travers d'un axe (21) entre un premier organe ou cylindre (20) et un deuxieme organe ou cadre (11) ont ete relativement difficiles a regler et ont tendance a coller. Dans la presente realisation, un rouleau (44) est monte de maniere pivotante sur une premiere structure de liaison (36) qui est elle meme montee de maniere pivotante par rapport au cylindre (20). Le rouleau (44) definit une surface (42) de came generalement circulaire. Une deuxieme structure de liaison (52) est montee sur le cadre (11) et une des jambes (100) d'un organe (98) generalement en forme de U est montee sur la deuxieme structure (52) de liaison tandis que l'autre jambe (102) est positionnee de maniere a definir une surface (106) agissant de concert contre le rouleau (44). Un dispositif de reglage (122) sert a regler l'autre jambe (102) de l'organe (98) generalement en forme de U tangentiellement et radialement par rapport au rouleau (44). Un reglage relativement facile et aisement accessible est ainsi possible. En outre, les problemes de collage sont reduits.

    Abstract: The flux dams used to form mounds of granular flux in submerged arc welding deteriorate rapidly because they are subjected to elevated temperatures and high heat. These flux dams also twist and distort creating gaps. Granular flux bleeds through these gaps. Flux is wasted and the welding arc may be exposed to the atmosphere. Flux dams are also awkward to move and slow production down. The apparatus and method disclosed herein overcome these problems by utilizing an elongate flux dam (19) that is stationary during welding and which extends for the length of the weld. The flux dam (19) is mounted on a heat exchanger (24) by a mounting plate (21) that minimizes thermal distortion of the flux dam (19). The heat exchanger (24), the mounting plate (21), and the flux dam (19) are pivotally connected to a support arm (26) that is mounted for motion about the platform (6) on a pivot point (32).

    Abstract: A slip control system for vehicles having spaced apart differentially driven wheels (200, 202) including means (220) for calculating wheel slip according to the ratio of wheel speeds, means (242, 230, 232) for entering a slip control mode wherein a braking force is applied to the slipping wheel and incrementally varied on a periodic review basis according to recalculated slip values. If slip increases or holds steady, the brake force is incrementally increased. As slip becomes less, the brake force is incrementally reduced, the particular increments of force reduction being selected in accordance with successive measurements of slip. A drive shaft signal (226) is compared to the high wheel speed signal to identify a wheel speed transducer failure.
