  • Patent number: 10400826
    Abstract: A method for forming a propshaft assembly that includes: providing a propshaft tube having a wall member that defines an inner tubular surface; providing a yoke with a yoke body and a pair of yoke arms that extend from the yoke body, the yoke body defining first and second locating portions and an adhesive groove that is disposed between the first and second locating portions; assembling the yoke to the propshaft tube such that the first locating portion engages the inner tubular surface in a slip-fit manner and the second locating portion engages the inner tubular surface in an interference-fit manner; heating the propshaft tube and the yoke; and injecting an adhesive through the propshaft tube into the adhesive groove when the propshaft tube and the yoke are at a temperature that is greater than or equal to a predetermined minimum adhesive injection temperature. A propshaft assembly is also provided.

  • Patent number: 8715127
    Abstract: An axle assembly having a heat sink coupled to an axle housing assembly for ejecting heat from the axle assembly. The heat sink includes an air channel having a body coupled to the carrier housing assembly such that heat is conducted from the carrier housing assembly to the body of the air channel and an air passage formed in the body and having an open leading end and an open trailing end, the leading end being positioned relative to the carrier housing assembly to permit air flowing over the axle assembly when the axle assembly is in use to be received into the air passage such that heat is conducted from the body to the air flowing through the air passage, and the trailing end being positioned relative to the carrier housing assembly to permit air received in the air passage to be expelled through the trailing end.

  • Patent number: 5105674
    Abstract: A multiple-shaft transmission having multiple gear ratios, at least one ro having a gearset with gear elements (58, 144, 204) that are journalled on their respective shafts (44, 112, 206) and that are continuously in mesh, each shaft carrying a clutch assembly (178, 188) that may be selectively engaged and disengaged to complete and to interrupt a torque flow path through the gearset whereby the gear elements are isolated from the input and output driven and do not contribute to the total inertia mass of the driven rotating components of the transmission when they do not form a part of the torque flow path, thus reducing gear rattle and reducing shift efforts required to effect gear ratio changes.

  • Patent number: 4811615
    Abstract: A mechanism arranged in combination with a multiple ratio transmission for eliminating gear rattle in the various gear ratios and neutral position of the transmission. Such mechanism includes a gear network that is preloaded with a spring arrangement which imparts a spring torque to each gear mesh in the transmission. The spring torque provided by the spring arrangement has a magnitude greater than the inertia torque of the gear meshes arranged in the transmission and is capable of overcoming torsional acceleration imparted to those gear meshes.
