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] With reference to the accompanying drawings, the parallel power differential differential has two same-speed differentials 1 and reverse-speed differentials 2 with identical structures, the same-speed differential 1, reverse-speed differential 2 and constant-speed differentials. The reverse drive idler 18 is arranged in the casing 21 to form the whole differential. The co-speed differential 1 and the counter-speed differential 2 are arranged symmetrically on the upper and lower sides in parallel; the co-speed differential gear frame 3 and the co-speed differential driving gear 19 are integrated; the co-speed differential planetary gear 5 is installed vertically On the same-speed differential gear carrier 3, the same-speed differential planetary gear 5 meshes with the same-speed differential left half-shaft bevel gear 7 and the same-speed differential right half-shaft bevel gear 13 on both sides to ensure The same speed differential left side bevel gear 7 and the same sp...

The invention relates to a parallel type dynamic speed difference adjustment differential. The differential is characterized by comprising a same-speed differential and an inverse-speed differential which have identical or similar structures, wherein the same-speed differential, the inverse-speed differential and a constant-speed reversing transmission idle wheel are arranged inside a shell so as to form a differential whole body; and the same-speed differential and the inverse-speed differential are parallelly and symmetrically arranged on an upper side and a lower side so as to effectively control the speed difference of two turning wheels, realize complete constant speed and precisely controllable revolution speed difference, and subsequently realize stable linear motion and precise steering. By using the speed difference adjustment differential, constant-speed driving rotation is subjected to constant-speed decomposition, and differential-speed driving rotation is subjected to constant-speed and reverse decomposition at the same time; constant-speed transmission and differential-speed transmission inside the differential are independent and superposable; and two driving moments and revolution speeds are not influenced each other nor interfered with each other, so that controllable constant-speed rotational distribution and differential-speed rotational distribution can be precisely realized, and the disadvantages that the conventional differential can freely decompose output driving rotation but cannot decompose a given revolution speed difference are overcome.
