Abstract: Described herein is an axle system wherein the attachment locations of trumpet arms are isolated from the side cover side walls and gearbox housing side walls. In one embodiment, the axle system comprises a gearbox housing comprising lateral ribs/webs, compression tubes extending from one side to an opposite side of the gearbox housing, and couple holes positioned around a perimeter of the gearbox housing, a first side cover coupled to the gearbox housing via bolts and fasteners, a first trumpet arm coupled to the first side cover and the gearbox housing via fasteners, an attachment location of the first trumpet arm being isolated from the side walls of the gearbox housing and the side walls of the first side cover, and a second trumpet arm coupled to the gearbox housing via fasteners, the attachment location of the second trumpet arm being isolated from the side walls of the gearbox housing.

Abstract: Methods and systems for operating a tandem axle that includes two electric machine propulsion sources are described. In one example, a controller determines a presence or absence of a beat signal that may be generated via rotating components of the tandem axle. Operation of the tandem axle may be adjusted in response to detection of the beat signal.

Abstract: A system for an electric drive unit. The electric drive unit includes, in one example, a first shaft with a through shaft opening and a second shaft axially aligned with the first shaft. The electric drive unit further includes a through shaft that axially extends through the through shaft opening and removably attaches to the first shaft and the second shaft.

Abstract: In one example, a line of transmissions is provided comprising, a first transmission and a second transmission. Each transmission includes an input shaft with a first pair of gears arranged thereon and a first clutch positioned therebetween designed to selectively rotationally couple at least one of a first gear and a second gear of the first pair of gears to the input shaft. Each transmission includes a layshaft with a second pair of gears fixedly coupled thereto. Each transmission includes an output shaft with a third pair of gears arranged thereon and a second clutch positioned therebetween designed to selectively rotationally couple at least one of a third gear and a fourth gear in the third pair of gears to the output shaft. The first transmission has the second gear fixed to the input shaft. The second transmission has the fourth gear fixed to the output shaft.

Abstract: Systems and methods for an axle shaft system of an electric vehicle are provided. A reversible axle shaft flange is optionally couplable to the axle shaft such that in a first orientation, the reversible axle shaft flange is coupled to the axle shaft and in a second reverse orientation, the reversible axle shaft flange is decoupled from the axle shaft. The reversible axle shaft flange is detachable in order to reverse an orientation and reinstall in the other orientation. The reversible axle shaft flange couples to a wheel hub via a plurality of fasteners such that torque is transferred from the axle shaft to a wheel via the reversible axle shaft flange in the first orientation. With the axle shaft in a decoupled state, rotation is not transferred from the wheel to an electric machine such that a towing operation with wheels in contact with ground is possible.

Abstract: A wide mouth container or jar suitable for storage of viscous jells, such as hair dressings in which the closure includes provision for preventing unauthorized removal by children. To open the closure, it must be rotated to a predetermined location relative to the container to align a small radially extending tab opposite a corresponding gap in a radially extending flange on the outer surface of the container, following which the tab is pushed in a direction away from the flange to free to closure.
