Abstract: Disclosed is a cardan shaft sliding assembly suitable for both a gearbox-differential arrangement, which provides the cardan shaft freedom of motion in the axial direction, and for an undercarriage arrangement between two axles. The cardan shaft sliding assembly has multiple mounting diameters of different dimensions positioned on a yoke shaft in order to provide housing and assembly of the protective cover in both the gearbox-differential arrangement and the undercarriage arrangement between two axles. The yoke shaft with the mounting diameters provides the cardan shaft with freedom of motion in the axial direction and is one of the parts forming the sliding assembly.

Abstract: A propeller shaft includes a rotational shaft and a constant-velocity joint. The constant-velocity joint includes an inner race member connected to the rotational shaft, a rolling member disposed on an outer periphery of the inner race member in a radial direction relative to a direction of a rotational axis of the rotational shaft, and a tubular outer race member provided on an outer periphery of the rolling member in the radial direction and configured so that a rotational force of the rotational shaft is transmitted thereto via the rolling member. The outer race member has first and second end portions of the outer race member in the direction of the rotational axis. The outer race member includes a centering portion provided at the first end portion and formed so as to be smaller than a maximum diameter of the outer race member in the radial direction.

Abstract: A boot for a constant velocity universal joint includes large- and small-diameter mounting portions to be mounted to an outer joint member and a shaft, respectively, with boot clamps, a bellows portion integrally coupling the large- and small-diameter mounting portions to each other, and a cylindrical shoulder portion formed at a bellows portion-side end of the large-diameter-side mounting portion, and connected to the bellows portion through two auxiliary crest portions and one auxiliary trough portion between the auxiliary crest portions. A radial distance between each of the auxiliary crest portions and the auxiliary trough portion is shorter than a radial distance between a crest portion and a trough portion. A diameter passing through a center of the radial distance between each of the auxiliary crest portions and the auxiliary trough portion is larger than a diameter of the cylindrical shoulder portion.

Abstract: An implement plug device for plugging an implement yoke so as to keep the yoke clean and free of any debris such as dirt, mud, rust, insects, and the like when not in use. The implement plug device generally includes a main body and a handle portion which is wider than the main body. The main body of the implement plug device generally includes splines extending across at least a portion of the main body for engaging within grooves defined between corresponding splines within the opening of a yoke to prevent rotation of the implement plug device within the yoke. One or more of the splines of the implement plug device may include one or more spline cutouts to engage with corresponding locking members within the yoke. The handle portion will generally include one or more cutouts to aid in removing the implement plug device from the yoke.
