Abstract
The utility model provides a universal wheel with a toothed brake, which is a single row of rims of the universal wheel consisting of a plurality of arc-shaped cone rollers, a plurality of bearings, a plurality of spindles, a roller bracket and a hub. The side face of the hub is fixedly provided with an inner gear ring, the bearings, a shaft sleeve and a flat central shaft are arranged in inner holes of the hub, the shaft sleeve is fixed on a vehicle frame, the center of the inner gear ring is provided with a sliding plate seat, a sliding plate with teeth and the flat central shaft, the sliding plate with the teeth can move up and down between the sliding plate seat and the flat central shaft, a spring is arranged between the sliding plate with the teeth and the sliding plate seat, and the sliding plate with the teeth can be ejected by the spring. When the top part of the sliding plate with the teeth is pressed by a pressing plate, the spring is compressed, and the sliding plate with the teeth slides down to be embedded in the toothed slot of the inner gear ring. A roller pressing plate is arranged under the sliding plate with the teeth, the arc-shaped cone rollers on the lower part of the wheel can be pressed by the roller pressing plate, and then the wheel cannot rotate. When the pressing plate is lifted, the spring bounces back, the sliding plate with the teeth and the roller pressing plate rise, and then the wheel can rotate. The pressing and lifting of the pressing plate are completed through a connecting rod mechanism. A vehicle with the wheel can run in any direction with no change of the direction of the wheel, and the wheel is convenient to use and has a wide scope of application.
