The embodiment of the utility model provides a wheel tread variable diameter variable wheel hub and use wheel tread variable diameter variable wheel hub's vehicle is related to. As shown in fig. 1 to 4, a wheel hub 100 includes a center stator 101 for mounting on a brake disc (not shown) of a vehicle, a track adjusting moving portion 103 movable in a track adjusting direction a with respect to the center stator 101 to adjust a track, a plurality of rim blocks 105 combinable together to form a rim, and a plurality of radially expandable spokes 107 connecting the plurality of rim blocks 105 and the track adjusting moving portion 103, respectively. Each of the radially expandable spokes 107 includes a radially fixed portion 109 fixed to the track adjusting moving portion 103, and a radially sliding portion 111 fixed to the corresponding rim block 105 and capable of driving the corresponding rim block 105 to slide radially relative to the radially fixed portion 109.
The wheel hub 100 may further be provided with a track adjustment driving means for driving the track adjustment moving part 103 to move in the track adjustment direction a with respect to the center stator 101. In some embodiments, the track-adjusting driving means may include a moving motor 113 disposed between the center stator 101 and the track-adjusting moving portion 103. The center stator 101 is provided with a first groove 115 with threads at a position corresponding to the moving motor 113, the track adjusting moving portion 103 is provided with a second groove 117 with threads, and the moving motor 113 moves the track adjusting moving portion 103 relative to the center stator 101 in the track adjusting direction a by engaging with the threads in the first groove 115 and the second groove 117. In some embodiments, the mating of the translation motor 113 with the threads in the first and second grooves 115, 117 is similar to the mating of a rack and pinion.
The track adjusting moving portion 103 includes or is itself an annular structure that is movably fitted over the center stator 101 along the track adjusting direction a. Typically, the track adjustment direction a is a direction perpendicular to the radial direction of the hub 100. The radially fixed portions 109 of the plurality of radially expandable spokes 107 are uniformly distributed on the outer periphery of the track adjusting movable portion 103 in the circumferential direction of the track adjusting movable portion 103, and extend from the outer periphery of the track adjusting movable portion 103 toward the corresponding rim block 105. The radial sliding portion 111 extends from the corresponding rim block 105 toward the track adjusting movement portion 103. In some embodiments, radial slide 111 nests on radial fixed portion 109 and surrounds at least three surfaces of radial fixed portion 109. For example, in the illustrated embodiment, the radial sliding portion 111 is nested in the radial fixing portion 109, and surrounds three surfaces of the radial fixing portion 109, so that the sliding guiding function of the radial sliding portion 111 can be realized by such a nested design. In some embodiments, other guiding structures may be further provided, for example, at least one guiding groove may be provided on the radial fixing portion 109, and a corresponding sliding block may be provided on the radial sliding portion 111, and the sliding block and the guiding groove cooperate to achieve further guiding function.
The hub 100 may further be provided with a radial sliding driving means for driving the radial sliding portion 111 to slide radially with respect to the radial fixing portion 109. The radial slide driving means may include a piston device 119 disposed between the track adjusting moving portion 103 or the radial fixing portion 109 and the corresponding radial slide portion 111 or the rim block 105. The piston device 119 may be configured to be coupled to the track adjusting moving portion 103 or the radial fixing portion 109 at one end and to be coupled to the corresponding radial sliding portion 111 or the rim block 105 at the other end. In the illustrated embodiment, the piston device 119 is connected to the track adjusting movement portion 103 at one end and the corresponding rim block 105 at the other end.
By the described structural design, the track width and diameter of the wheel hub 100 are adjustable, such that at least one of the track width and diameter can be adjusted according to specific requirements. The change of the track is realized by driving a track adjusting driving device (such as a moving motor 113) to drive the track adjusting moving part 103 to move along the track adjusting direction a through an external electric signal, and the final position can be locked after the target position is reached. The hub diameter is changed by driving a radial slide driving device (e.g., a piston device 119) by an electric signal to push the slide radial slide portion 111 to slide radially relative to the radial fixing portion 109, so as to extend and contract the retractable spoke 106 in length in the radial direction. By the telescopic movement of the telescopic spokes 106 connecting the rim blocks 111 and the tread adjusting movement portion 103, the plurality of rim blocks 111 can be folded or unfolded, and combined together to form a rim surrounding the tread adjusting movement portion 103 and for supporting the tire. In fig. 1-4, a plurality of rim segments 111 are shown in a closed position, wherein adjacent rim segments 111 are in contact with each other, with substantially no gaps therebetween, and the rim and, thus, the entire hub 100, are in a state of minimum diameter. As the radial sliding portion 111 slides in a radial direction toward a direction away from the radial fixing portion 109, the plurality of rim blocks 111 are gradually opened to a state (not shown) spaced apart from each other, and the gap between the adjacent rim blocks 111 is gradually increased, so that the diameter (size) of the rim and to the entire hub is gradually increased, adjustment of the diameter is achieved, and locking of the final position can be performed after the target size is reached.
The embodiment of the utility model provides an in wheel hub and use this wheel hub's vehicle can realize wheel track and wheel hub variation in size to can satisfy the engine compartment part arrangement demand under the different wheel tracks, satisfy the ground clearance design under the different wheel hub size circumstances, satisfy the molding demand under various wheel tracks and the big or small prerequisite of wheel hub, make the wheel hub design more flexible.
The foregoing specific embodiments are provided so that this disclosure will be thorough and complete, and will not be limited to these specific embodiments. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit of the invention.
