A wheel assembly is disclosed. The wheel assembly may have a hub with a first spline, a second spline, and a slot separating the first spline and the second spline. The first spline, the second spline, and the slot may extend from a front end to a rear end. The wheel assembly may also have an outer rim configured to mount a tire. The wheel assembly may further have an inner rim extending from a rim front end to a rim rear end. The inner rim may have a notch disposed at the rim front end and a tab disposed at the rim rear end. The tab may slidingly engage with the slot. The wheel assembly may have a locking block, which may slidingly engage with the notch and the slot at the front end. Further, the wheel assembly may have a bolt connecting the mounting block to the hub.

A wheel for a vehicle is disclosed. The wheel comprises a central portion attachable to a vehicle hub and a rim arranged radially outside the central portion for supporting a wheel tire. The central portion has a series of cavities configured to receive a corresponding adapter. A cavity of the series of cavities has a through hole. The through hole is aligned in an alignment direction for alignment with a through hole of a corresponding adapter for traversal by a mounting element to attach the central portion to the vehicle hub. The cavity is configured to receive the corresponding adapter in a unique rotational position with respect to the alignment direction. The cavity includes first and second cylindrically shaped and axially aligned volumes. The first volume is bounded by a first receiving wall portion that extends substantially parallel to a front side surface of the central portion. The second volume extends from the first volume towards a back side surface of the central portion. The second volume is located radially within a radial outer periphery of the first volume.

A roller unit having an integrated fastening portion includes a supporting shaft fastened to a containing body or a containing main body that can slide and having first and second flanges formed in multi steps with different outer diameters, a rotating body rotatably fixed to a side of the supporting shaft, and a washer coupled to a side of the rotating body to surround and fix the second flange, thereby preventing separation of the supporting shaft and the rotating body. Therefore, it is possible to more conveniently combine the supporting shaft and the rotating body and to prevent separation of the supporting shaft and the rotating body, whereby is possible to improve various functions.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.

The invention relates to a Wheel Hex Hub Assembly designed for remote-controlled cars, offering adjustable features for convenient customization. The assembly comprises a Threaded Hex Hub, a Hub Face, and a Hub Spacer. The Threaded Hex Hub connects the wheel to the axle with a hex shape cutout and threaded holes for secure fastening. The Hub Face provides a flat surface with a machined cylindrical step for wheel centering and a central hole for axle shaft attachment. The Hub Spacer allows for length adjustment in the assembly.

Methods and systems are provided for coupling mechanism of a wheel. The coupling mechanism of a wheel includes a screw with a threaded portion, a block with an internal threaded portion, and a coupler mechanically coupled to the screw. The coupler has a radially inner surface configured to couple with a drive shaft and a radially outer surface configured to couple with a spindle, where the screw is configured to engage the coupler with the drive shaft when actuated in a first direction and disengage the coupler from the drive shaft when actuated in a second direction, opposite the first.

The invention provides a wheel fastening system for a vehicle. An embodiment consistent with the invention includes a hub on which a wheel is mountable, the hub comprising a threaded surface, and a nut which is engageable with the threaded surface to fasten the wheel to the hub. The embodiment further includes a tool including a socket that is engageable with the nut; a reaction element that is engageable with a reaction surface on the hub or the wheel, wherein, when the wheel is mounted on the hub and the nut is engaged with the threaded surface, the socket and the reaction element are simultaneously engageable with the nut and the reaction surface, respectively; and a gearbox configured to simultaneously apply opposing torques to the socket and the reaction element. In this manner, the tool can be used to simultaneously apply opposing torques to the nut and the reaction surface.
