Abstract: A constant velocity joint includes an outer part having an opening and a plurality of axially extending race grooves in the opening, an inner part at least partially located in the opening and having an outer surface with a plurality of axially extending race grooves, and a plurality of balls located between in inner and outer parts in the grooves. A first subset of the race grooves in the outer part and/or a first subset the race grooves in the inner part includes a section that follows a curved path in the axial direction.

Abstract: A method for connecting a constant velocity joint having a bell and a shaft to a wheel bearing having an opening, the shaft being oversized relative to the opening, includes applying an adhesive to the shaft and/or the opening, the adhesive in an uncured state being configured to reduce a coefficient of friction between the shaft and the opening, pressing the shaft into the opening to form a press connection between the shaft and the wheel bearing, and curing the adhesive or allowing the adhesive to cure. Also a subassembly formed by the method.

Abstract: A tripod joint includes a multi-part pot having an interior and a plurality of raceways for supporting a plurality of rollers in the interior. The pot includes a housing having an open end and a base at the end of the housing opposite the open end, and the base may be formed separately from the housing or one-piece therewith. The raceways may be formed by inserts mounted in the interior which inserts may have a hardness greater than a hardness of the material of the housing.

Abstract: A subassembly includes a wheel hub and a constant velocity joint. The constant velocity joint includes a bell and the wheel hub is connected to the bell by high-pressure internal forming. Preferably, the wheel hub includes an axial projection disposed radially inside a connecting section of the bell, the projection interacting with the connecting section during the high-pressure internal forming process in order to connect the wheel hub to the bell. The projection is preferably configured to deform plastically and is connected to the bell in an interference-fit manner. Further, the wheel hub preferably provides an inner ring of a bearing unit and either the bell of the constant velocity joint provides another inner ring or a separate inner ring is disposed between the wheel hub and the bell.

Abstract: A constant velocity joint includes an outer part having a connecting portion and an opening portion and a plurality of axial grooves forming outer raceways, and an inner part having a plurality of axial grooves forming inner raceways. Each outer raceway and inner raceway form a raceway pair, a ball being disposed in each raceway pair. Each raceway pair defines a region in axial cross-section with respect to a groove longitudinal axis conceptually divided into four quadrants. The outer raceway is in the first and second quadrants and the inner raceway is in the third and fourth quadrants. With torque transmission in a first direction, the ball has two contact points in the first quadrant and/or two contact points in the third quadrant, and with torque transmission in a second direction, the ball has two contact points in the second quadrant and/or two contact points in the fourth quadrant.

Abstract: A subassembly includes a wheel hub and a constant velocity joint having a bell in which the wheel hub is connected to the bell by friction welding. A first one of the wheel hub and the bell may include an axial projection and the other one of the wheel hub and the bell may include a recess in which the axial projection is received. Also a method of connecting a wheel hub to a constant velocity joint by friction welding.

Abstract: A rolling-element bearing unit for use in a motor vehicle wheel or in a motorbike rocker arm includes outer and inner raceway elements and a set of rolling elements between the inner and outer raceway elements such that the inner and outer raceway elements are pivotable or rotatable relative to each other and also a lubricant reservoir body in the bearing interior for storing and dispensing a lubricant, the body including bridge elements extending between adjacent pairs of the rolling elements and a side ring connecting the bridge elements.

Abstract: A multi-row bearing assembly includes first and second rolling-element bearings having first and second bearing rings and first and second rows of rolling elements therebetween, respectively, each ring having exactly one guide flange. An intermediate space exists between the first and second rows of rolling elements, and a first side of each row of rolling elements faces the intermediate space and a second side of each row of the rolling elements is remote from the intermediate space. The guide flanges of the first and third bearing rings guide the first sides of the rolling elements, and the guide flanges of the second and fourth bearing rings guide the second sides of the rolling elements.

Abstract: A method of forming a flexible elastomer polymer fluid jacket for a plastic processing mold, and a novel elastomer polymer fluid jacket. The method comprises attaching channel formers to the rear surface of the metal shells of the mold sections to define a desired flow configuration, securing a support casting to the rear surface of the metal shells spaced from the channel formers to define a designed cavity, feeding a curable elastomer polymer typified by silicone elastomers into the cavity, curing the elastomer polymer, and removing the channel formers whereby the cured elastomer polymer forms a fluid jacket. A mold having mold components with flexible polymer fluid jackets between the mold shells, preferably nickel shells, and support castings permit enhanced heat transfer to the mold cavity while providing improved thermal insulation to the mold. The elastomer polymer also enables multiple modular configurations of the heating and/or cooling function of the mold.
