Embodiment

Below in conjunction with accompanying drawing 1-6, the utility model is further described:

As shown in Figure 1,2 and 3, hand clutch comprises shell 11, support 15, driven wheel of differential 12, drive bevel gear 13, hollow shaft 22, bearing pin 23, geared sleeve 24, return unit 25, push rod 26 and handle with sleeve 27.

Shell 11 is tubular, bottom end opening and by edge one circle screw be fixed on support 15, top offer several heat radiation hole.Shell 11 sidewall is provided with opening, allows the tail end of hollow shaft 22 laterally pass.As shown in Figure 4, support 15 bottom is round structure, and center has groove 153, allows the tailing axle 3 of motor 1 pass perpendicularly through.Support 15 tip portion has two symmetrical engaging lugs 151, and engaging lug 151 top is provided with installs through hole 152, installs in through hole 152 and is provided with sliding sleeve.

As shown in Figures 2 and 3, driven wheel of differential 12 is removably connected with tailing axle 3 by key, thus is fixedly mounted on tailing axle 3.Drive bevel gear 13 relatively driven wheel of differential 12 is vertically arranged, and comes optionally to engage or drop out of gear with driven wheel of differential 12 by transverse shifting.

As shown in Figure 5, hollow shaft 22 is divided into head section 223 and rear 224.The two ends of head section 223 are arranged in two sliding sleeves respectively, thus can rotate by opposite brackets 15.The both sides of sliding sleeve have back-up ring, prevent hollow shaft 22 from transverse shifting occurring.Head section 223 is symmetrically arranged with the bar hole 221 that two run through outer wall.Rear 224 stretches out support 15 and shell 11, and its outer surface is configured to first fitting surface 222 matched with handle with sleeve 27.

Geared sleeve 24 is slidably located on hollow shaft 22, and its end is symmetrically arranged with the pin-and-hole that two run through outer wall.Drive bevel gear 13 is fixed on the other end of geared sleeve 24.Return unit 25 is stage clip, is set in hollow shaft 22 outside.One end of return unit 25 is resisted against on the inner side surface of engaging lug 151, and an end of the other end and geared sleeve 24 abuts against, and can apply Driving force when it resets to geared sleeve 24 and drive bevel gear 13.

It is inner that push rod 26 is partly contained in hollow shaft 22, and its tail end stretches out certain length from hollow shaft 22.The head end of push rod 26 has the cotter way vertically running through it.Bearing pin 23 is elastic cylindrical pin, and it, through cotter way and bar hole 221, is connected with pin-and-hole close-fitting at end.Bearing pin 23, under the promotion of push rod 26 or return unit 25, can slide along bar hole 221 between the ends.

As shown in Figure 6, handle with sleeve 27 comprises sleeve part 271 and handle part 272.Sleeve part 271 internal surface is configured to the second fitting surface 273 matched with the first fitting surface, thus together with handle with sleeve 27 is connected with hollow shaft 22.In mating process, the tail end of push rod 26 can be pushed hollow shaft 22 inside by the interior edge face of sleeve part 271, and push rod 26 promotes bearing pin 23, and bearing pin 23 driven gear cover 24 promotes drive bevel gear 13 and moves, and drive bevel gear 13 is engaged with driven wheel of differential 12.

Handle part 272 and the machine shaping of sleeve part 271 one.After sleeve part 271 and hollow shaft 22 connect, handle part 272 drives hollow shaft 22 to rotate, and drives drive bevel gear 13 to rotate by bearing pin 23 and geared sleeve 24.

Working principle:

When not having power failure or fault, handle with sleeve 27 is not assembled on hollow shaft 22; The tail end of push rod 26 stretches out certain length from hollow shaft 22, bearing pin 23 is positioned at one end of bar hole 221, in the raw, drive bevel gear 13 and driven wheel of differential 12 are in drop out of gear state to return unit 25, and the rotating shaft of motor 1 exports the electric driving force of internal stator rotor structure generation.

When there is power failure or electrical failure, handle with sleeve 27 is coupled on hollow shaft 22, and the tail end promoting push rod 26 enters hollow shaft 22 inside, makes bearing pin 23 slide into the other end of bar hole 221, geared sleeve 24 compresses return unit 25, and drive bevel gear 13 moves to and engages with driven wheel of differential 12.After connecting, handle part 272 drives drive bevel gear 13 to rotate, and then drives driven wheel of differential 12 and tailing axle 3 to rotate, and makes motor 1 export manual drives power.

When after energising or fault restoration, handle with sleeve 27 unloads from hollow shaft 22, and push rod 26 tail end loses the impetus of handle with sleeve 27, under the reset response of return unit 25, again exit hollow shaft 22, drive bevel gear 13 returns initial position, thus closes with driven wheel of differential 12 drop out of gear.

Below be only preferred embodiment of the present utility model, not any pro forma restriction done to the utility model.Other had not only engaged firmly but also docked mode for convenience detach can also to adopt between sleeve part 271 with hollow shaft 22 that internal and external threads coordinates, elasticity engages etc.Push rod 26 can not also arrange cotter way, and its head end abuts with bearing pin 23, can play the effect promoting bearing pin 23 equally.
