A method for forming a rotor hub that includes a sheet metal cylinder including spline teeth including angularly spaced crests and valleys, a tube surrounding the cylinder, secured to the crests and supporting a rotor thereon, a hub secured to the cylinder and supported for rotation, a torque converter, and a flex plate secured to the hub and the torque converter.

A front module housing an electric motor/generator and an engine disconnect clutch for a modular hybrid transmission includes a valve body that houses a hydraulic valve which operates the engine disconnect clutch. The valve body is located at an angle relative to the bottom of the front module, providing fastener clearance for mounting the front module to an internal combustion engine.

Embodiments disclosed herein describe systems and methods for a universal electric engine mount for vehicles, wherein the universal engine mount may be configured to be installed into at least any front wheel drive vehicle.

An electrical machine comprising: at least one stator, at least one module, the at least one module comprising at least one electromagnetic coil and at least one switch, the at least one module being attached to the at least one stator; at least one rotor with a plurality of magnets attached to the at least one rotor, an integrated electrical differential coupled to at least one of the rotors, the at least one integrated electrical differential permitting the at least one rotor to output at least two rotational outputs to corresponding shafts, wherein the at least two rotational outputs are able to move the shafts at different rotational velocities to one another. The electrical machine is configured to fit into a housing, and that can be retrofitted into a conventional vehicle by replacing the mechanical differential.

A system for venting a hybrid electric powertrain includes a module defining a first volume containing a clutch and an electric machine, a housing defining a second volume containing an automatic transmission, and lines producing mutual pneumatic connections among the first volume, the second volume and ambient atmosphere.

A modular kit system (14) for converting a traction drive (40) of a motor vehicle (10) from a drive having an internal combustion engine (11) to an electric traction drive (40). The kit (14) includes a mechanical support structure (15) having a mechanical connection interface (33) for fastening the support structure (15) in an engine compartment (12) of the motor vehicle (10) in place of the internal combustion engine (11), and electrical equipping components (16) for equipping the support structure (15), wherein the support structure (15) has equipment places (28) each for fastening one of the equipping components (16) in and/or on the support structure (15), and each equipment place corresponds, with respect to a form and/or a fastening device, with a form and/or a fastening device of a fastening region of the associated equipping component (16) for which the equipment place is provided.

A powertrain module includes an input, first bulkhead supporting the input for rotation, a hub, an electric machine including a stator connected to the first bulkhead and a rotor connected to the hub, a clutch for alternately opening and closing a drive connection between the input and the rotor, and a second bulkhead supporting the input for rotation.

A rotor hub includes a sheet metal cylinder including spline teeth including angularly spaced crests and valleys, a tube surrounding the cylinder, secured to the crests and supporting a rotor thereon, a hub secured to the cylinder and supported for rotation, a torque converter, and a flex plate secured to the hub and the torque converter.

An electric vehicle traction drive assembly includes a variable-speed electric motor for providing the torque. A multi-speed transaxle multiplies the torque of the electric motor through the vehicle operator's selection between more than one gear ratio. An adapter mechanically couples the motor and the transaxle to integrate the motor with the transaxle keeping an output shaft of the motor center-aligned with an input shaft of the transaxle.

A baffle for use in a fuel tank has a sidewall and an interior space. The sidewall is formed of a flexible material so as to be radially compressible. The compressibility of the sidewall allows the baffle to be inserted through a hole which is smaller in diameter than the uncompressed diameter of the baffle. The baffle is preferably also longitudinally compressible so that it can be mounted in fuel tanks of varying depths.
