A tire hoist system mounted beneath a vehicle body and supporting a spare tire for raising and lowering. The tire hoist system comprises a take-up reel rotatable about a reel axis; a flexible support member; and a tire support for a spare tire. The flexible support member is coupled to the take-up reel. A reduction gear system includes a plurality of meshed gears, including a reduction input gear. An input gear system has (a) an output gear coupled to the reduction input gear of the reduction gear system such that rotation of the output gear drives the reduction input gear, (b) a driving input gear meshed with the output gear, and (c) an input element fixed with the driving input gear and engageable by a drive tool. The output gear is rotated about an output axis parallel or coincident with the reel axis and the input element and the driving input gear is rotatable about an input axis oriented at an angle to the reel axis. The input gear system is an adapter input gear system comprising an input gear system housing, and is assembled separately from the reduction gear system and mounted by the input gear system housing being mounted to an exterior surface of the reduction gear system housing. A method for adapting a tire hoist system is also disclosed.

In various embodiments, a generative design application generates and evaluates automotive designs. In operation, the generative design application computes a first set of metric values based on a set of metrics associated with design goal(s) and a first set of parameter values for a parameterized automobile model. The generative design application then performs optimization operation(s) on the first set of parameter values based on the first set of metric values to generate a second set of parameter values. Subsequently, the generative design application generates at least one design based on the second set of parameter values that is more convergent with respect to at least one of the design goals than a previously generated design. Advantageously, less time and effort are required to generate and evaluate multiple designs and then optimize those designs relative to more manual prior art approaches.

A vehicular exterior rearview mirror assembly includes a base portion configured for attachment at an exterior portion of a vehicle, a mirror head having a mirror reflective element, and an actuator within the mirror head. When the mirror actuator is electrically operated, the mirror actuator moves the mirror head and the mirror reflective element together and in tandem relative to the base portion. The mirror reflective element is adhesively attached at a mirror back plate. The mirror back plate is attached at a head mounting plate, which is attached at the mirror actuator. A service recess is at and between the mirror back plate and the head mounting plate and is accessible from exterior the mirror head. The service recess is configured to enable detachment of the mirror back plate, with the mirror reflective element adhesively attached thereto, from the head mounting plate.

A vehicle disassembly system for disassembling a vehicle by moving the vehicle through a plurality of discrete workstations specifically adapted for select de-pollution and dismantling procedures encountered during the end-of-life vehicle recycling process. A vehicle disassembly system exemplifying the principles of the present invention may comprise a primary de-pollution and disassembly line and an engine disassembly line. The primary de-pollution and disassembly line may include one or more de-pollution stations, one or more intermediate, part removal stations, and a conveyor apparatus for transmitting the end-of-life vehicle from the de-pollution stations to the part removal stations. The engine disassembly line may include an overhead track support frame, a trolley assembly, one or more height adjustable loading tables, one or more height adjustable work tables, and one or more height adjustable un-loading tables.
