This creation is a kind of device of wheelchair transmission of related what,It is connected with the wheel body for setting what wheelchair two sides respectively simultaneously,And wheel chair transmission device include one with those wheel bodys connection actuation differential mould group,One is arranged the steering module at what wheelchair side with the power-equipment of differential mould group connection actuation and one,And steering module system has an at least deflecting roller; And when original place convolution to be carried out,System's operation steering module swings deflecting roller towards one side,And driving power-equipment averagely transmit power to those wheel bodys through differential mould group,And the wheel system ipsilateral with deflecting roller swaying direction and floor generate a resistance,And most of power are transferred to the other side wheel body due to experiencing the resistance by differential mould system,This creation is thereby enabled to reach the practical improvement for being able to carry out original place or so convolution in the minimum space of what.本創作為有關於一種輪椅傳動之裝置,其同時與分別設於輪椅兩側之輪體相連結,且輪椅傳動裝置包括有一與該些輪體連結作動之差速模組、一與差速模組連結作動之動力設備及一設置於輪椅一側處之轉向模組,且轉向模組係具有至少一轉向輪;而當欲進行原地迴旋時,係操作轉向模組使轉向輪朝一邊擺動,且驅動動力設備經差速模組平均傳遞動力給該些輪體,而與轉向輪擺動方向同側之輪體係與地板產生一阻力,且差速模組係因感受該阻力而將大多數動力傳遞至另一側輪體,藉此令本創作達到得以於極小的空間內進行原地左右迴旋之實用進步性。
