Embodiment Construction

[0037]Before the detailed structure and operation process of this tool is described in detail, it is necessary to introduce the structure and parameters related to the wheel installation of the vehicle. The wheels on the vehicle are usually fixed to the wheel mounting base such as the outer flange of the hub bearing unit or similar parts by a plurality of threaded fasteners (hereinafter referred to as wheel fasteners or fasteners). The wheel is referred to as a first base member, and the above-mentioned wheel mounting base is referred to as a second base member or wheel mounting member. Wherein, the wheel fastener is composed of a first component and a second component that can form a thread pair. A first member of the fastener, such as a nut, is screwed into a second member of the fastener, such as a screw, secured to the wheel mounting base. The wheel is placed between the first member of the fastener and the wheel installation base, so that the wheel can be firmly pressed ...

Abstract

An apparatus and method for attaching / detaching a circular array of threaded fasteners are suitable for mounting a fastener of a wheel to a vehicle or removing a fastener of the wheel from the vehicle. The apparatus has a bracket and a set of parallel rotating shafts mounted on the bracket, the axes of the rotating shafts being distributed in a circular array, or equivalently described as that,the axes of the rotating shafts being equidistantly distributed on a cylindrical surface. These shafts can be rotated about respective axes, and one end of these shafts can be used to hold and rotatesome type of threaded fastener. The threaded fastener is configured to form a thread pair with another type of threaded fastener on the wheel mounting member for securing the wheel to the wheel mounting member. The apparatus has an adjustment mechanism capable of synchronously adjusting the positions of all the rotating shafts such that the diameter of the cylindrical surface of the axis of all the above-mentioned rotating shafts varies between the first diameter and the second diameter, thereby adjusting the size of the rotating shaft spacing.
