This disclosure details electrified vehicles that are equipped with removable generators for increasing the electric range of the vehicles. An exemplary electrified vehicle includes a cargo space, such as a truck bed, and a generator removably positioned within the cargo space. The generator is adapted to selectively supply power for either charging a battery pack of the electrified vehicle or for propelling one or more vehicle drive wheels. In some embodiments, the generator is shaped like, and therefore disguised as, a toolbox.

Systems and methods for locally softening high strength steel are disclosed. One method may include heat treating one or more local regions of a steel component having a hardness of at least 450 HV to soften the local region(s) to a hardness of at most 250 HV. The heat treating may include heating only the local region(s) to a target temperature above an AC1 temperature of the component and below an AC3 temperature of the component. In another method, the heat treating may include heating only the local region(s) to a first target temperature above an AC3 temperature of the component, cooling the local region(s) to below an AC1 temperature of the component, and isothermally holding the local region(s) at a second target temperature below the AC1 temperature. The locally softened region(s) may allow for improved joining and/or trimming of the component.

A furnace assembly for hot-stamping vehicle components includes a support structure, a movable visor, a heat element, and a set of blocks. The support structure defines a cavity and an opening sized to receive a blank. The movable visor is mounted to the support structure and defines a first zone partially open to the cavity via the opening. The heat element is disposed within the cavity. Each of the blocks of the set of blocks is disposed on one side of the heat element to define a second zone and aligned with the opening to receive a vehicle component blank upon the blocks. The set of blocks and visor are arranged with one another such that portions of the blank are heated at different temperatures in the first zone and the second zone.

A value stream process or method for forming vehicle rails from extruded aluminum tubes includes the steps of extruding an aluminum tube and hydroforming the extruded aluminum tube into a vehicle rail. More specifically, the method includes extruding the aluminum tube, bending the aluminum tube, preforming the aluminum tube, hydroforming the aluminum tube into a vehicle rail, trimming the vehicle rail to length and then artificially aging the rail followed by batch chemical pretreatment. In an alternative embodiment the artificial aging and batch chemical pretreatment processes are performed in reverse order. In either of the embodiments, localized induction annealing to recover formability may be performed between bending and preforming, between preforming and hydroforming or both.
摘要:
A system and method of verifying that a part is heat treated to strengthen the part. The part is marked with a thermo-chromatic composition before heat treating. The part is then heat treated to strengthen the part and change the color of the thermo-chromatic composition to indicate successful completion of the heat treating process. A detector may act to prevent the inclusion of a non-heat treated part in an assembly by disabling an assembly tool. A controller may also provide data related to the completion of the heat treating process to be recorded in a database.

A vehicle tailgate includes a frame, pair of hinges, inner tailgate panel, and outer tailgate panel. The frame has a first outer side-member and a second outer side-member. Each of the outer side-members is secured to ends of a lower outer cross-member. The outer side-members each have an internal surface and an external surface. The internal surfaces define T-slots. One of the pair of hinges is secured to each external surface of the outer side-members. The inner and outer tailgate panels are secured to opposing outer sides of the frame such that the external surfaces of the outer side-members remain exposed.
