Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 6, a kind of wheel chair motor, comprise the mounting portion 1 for installing with wheel, described mounting portion 1 is fixed on motor casing 6 one end, described motor casing 6 loads in the inner core 21 of wheel hub 2, in described inner core 21, bearing 3 is installed, described bearing 3 inner ring is fixed on electricity and stops on the erecting bed 41 of 4, described electricity is stopped and is connected with the tail end output shaft 51 of motor 5 in 4, described motor 5 loads in motor casing 6 and front end output shaft 52 passes the driving hole 62 of motor casing 6, electricity to be stopped in 4 loading motor casings 6 and is closed the openend of motor casing 6, described motor casing 6 loads in inner core 21, described front end output shaft 52 has the tooth post engaged with the primary transmission tooth 71 connecting tooth 7,
Primary transmission tooth 71 one end of described company's tooth 7 loads in the mounting groove 61 of motor casing 6, the platform shaft portion 73 of the other end assembles with the company hole 81 of connecting plate 8, described connecting plate 8 is also provided with cover body 82, described cover body 82 covers on front end take-off lever 52 and blind end is provided with connection bearing 821, described connection bearing 821 loads in the installing hole 103 switching shell 10, in described switching shell 10, ring gear 9 is installed, described ring gear 9 medial surface is provided with toothed ring section 92, lateral surface is provided with draw-in groove 91, secondary transmission tooth 72 and toothed ring section 92 engaged transmission, a circle chute 101 is had outside described switching shell 10, a hole clipping 102 is also at least had bottom described chute 101, the dop 1101 of operating rocker 11 loads in hole clipping 102 and coordinates with draw-in groove 91, described operating rocker 11 is side walls hinged by hinge 15 and chute 101, and operating rocker 11 is provided with switching protruding 1102 away from dop 1101 one end, spring fitting groove 1103 is had in described switching projection 1102, in described spring fitting groove 1103, spring 12 is installed,
Switch post 14 switching circle 13 to be arranged on switching shell 10 side through the pilot hole switching circle 13, and the small end 1401 switching post 14 coordinates with chute 101;
