Abstract
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 syste…
