Problems solved by technology
[0002] At present, sports equipment with dual-wheel drive and steering, similar to wheelchairs, generally use dual power to drive the two runners respectively, and realize forward and backward movement and steering by controlling the speed of the two runners, but based on the open-loop control characteristics of the dual-power system , the two runners cannot well achieve constant speed rotation or precise steering, and often appear serpentine forward and unstable turning radius steering, and the motion control of wheelchair-type equipment is poor. It can effectively control the speed difference between the two runners, and can realize completely constant speed and precise controllable speed difference, and then realize smooth linear motion and precise steering

Embodiment Construction
[0008] Referring to the accompanying drawings, the dynamic differential differential is composed of two sets of ordinary differentials connected in series or in parallel, through the combination of transmission gear sets and their shafts, the rotation degrees of freedom of the left and right half shafts of the two sets of ordinary differentials are interlocked, so that A set of ordinary differentials only output the same direction and constant speed to the half shaft, and the rotational speed difference is locked and controlled by another set of ordinary differentials, and the other set of ordinary differentials only output the reverse constant speed to the half shaft rotation, while the constant rotational component is locked and controlled by a set of common differentials. The specific structure of the dynamic differential differential is: including the same speed differential, the reverse speed differential, the same speed drive worm, the reverse drive worm, the constant spe...

The invention relates to a power difference-adjusting differential, which is characterized by comprising two groups of common differentials connected in series or in parallel; through the combination of a transmission gear set and a shaft thereof, the rotating freedom degree interlocking of left half shafts and right half shafts of the two groups of common differentials is realized so that one group of common differentials only outputs homodromous uniform speed rotation to the half shafts; a rotating speed difference component is locked and controlled by the other group of common differentials which only outputs reverse uniform speed rotation to the half shafts; and a uniform speed rotating component is locked and controlled by the one group of common differentials. A specific structure of the power difference-adjusting differential comprises a circumferential speed differential, a reverse speed differential, a circumferential speed driving worm, a reverse speed driving worm, a uniform speed reverse transmission gear and a transmission shaft which are arranged in a differential shell. In the invention, controllable uniform speed rotation distribution and differential speed rotation distribution are precisely realized, the differential is suitable for a mechanism which is in uniform speed driving and simultaneously adjusts a rotating speed difference or a phase difference at any time; and the problems that two individual driving powers cannot work equivalently and a difference value is difficultly controlled are avoided.
