The invention discloses a mechanical double-overrunning
clutch main shaft outputting adaptive
automatic transmission high speed motor wheel chair hub. A reverse gear mechanism has a transmission ratioI which transmits a reverse gear power from an auxiliary shaft to a main shaft, a low
gear transmission mechanism has a transmission ration II which transmits a low gear power from the auxiliary shaft to the main shaft, and the
transmission ratio I is greater than or equal to the
transmission ratio II. According to the mechanical double-overrunning
clutch main shaft outputting adaptive automatictransmission high speed motor wheel chair hub, reasonable cooperation of two overrunning clutches is utilized, reasonable set of the transmission ratios are realized on the reverse gear structure andthe low gear mechanism, so that the overall structure is simple and compact, a
transmission line is shared by reverse
gear transmission, low
gear transmission and fast gear transmission, and no interference is produced, the overall performance of the mechanical adaptive
automatic transmission provided by the invention is ensured, the
adaptive capacity is relatively strong, the cooperation with theadaptive
automatic transmission mechanism is smooth and natural, the mechanical adaptive automatic transmission is applicable to the field of
electric cars, meanwhile, a reducing input structure is utilized, the mechanical adaptive automatic transmission is suitable for power input of the high speed motor, and the
overall efficiency is improved.
