Abstract
A wheel and a motor vehicle. The wheel includes: a wheel hub; a wheel rim, connected to the wheel hub through a plurality of spokes, the plurality of spokes being spaced apart from each other to form a plurality of through spaces; and a plurality of baffles, movably installed to the wheel relative to the wheel hub and configured to move relative to the wheel hub in response to changes in a speed of a vehicle to provide different shielding degrees for corresponding through spaces among the plurality of through spaces.
Claims13
A wheel, comprising:
- a wheel hub;
- a wheel rim, connected to the wheel hub through a plurality of spokes, the plurality of spokes being spaced apart from each other to form a plurality of through spaces;
- a plurality of baffles, movably installed to the wheel relative to the wheel hub and configured to move relative to the wheel hub in response to changes in a speed of a vehicle to provide different shielding degrees for a corresponding through space among the plurality of through spaces;
- and
- a plurality of grooves arranged on the wheel hub, wherein the plurality of baffles are movably installed into corresponding grooves among the plurality of grooves through respective protrusions of the plurality of baffles, so as to be able to move relative to the wheel hub along a specific trajectory under a guidance of corresponding grooves;
- wherein a trajectory of any one of the plurality of grooves is in a form of a logarithmic spiral curve with a starting end and a terminating end, and the starting end is closer to an origin point and the terminating end is further away from the origin point relative to a spiral direction of the logarithmic spiral curve.
