This moment, the kinetic current of first and second motor 1M1,1M2 all compiled via the first transmission shaft 1S1, the power output gear 1C3 of the one-level driving gear set 1C transmission gear 1C1 through rotating counterclockwise → clockwise rotate again, and wheels 1W advances.
Therefore, if the load of electric carrier immobilizes, start first and second motor 1M1,1M2, on average share on first and second motor 1M1,1M2 with the load that low reduction ratio fast driving electric carrier advances, the load that acts on first and second motor 1M1, the 1M2 is reduced by half, the characteristic of mat DC machine, load reduces under identical voltage, and speed then improves.
From the above mentioned, the embodiment of the invention three with first and second motor of simple circuit control 1M1,1M2 respectively the forward, reverse or stop mode of ending one of them motor drive and be engaged in transmission gear 1C1, small transmission gear 1D1, another transmission gear 1C2, big transmission gear 1D2 on first and second transmission shaft 1S1, the 1S2 with four groups of unilateral bearing 1C11,1D11,1C21,1D21, just can reach the effect that five sections speed changes and power merge, identical with the embodiment of the invention two functions, much simpler than speed reduction gearing complicated in traditional change speed gear box.
When electric carrier placed on the acclivity, motor is quiescence and do not have brake, carrier still had the function that can not glide by self-locking action of the present invention.Its self-lock mechanism is; When wheel 1W produces the application force that slides backward because of terrestrial attraction, when desiring traction power output gear 1C3 anticlockwise motion, drive one-level driving gear set 1 liang of transmission gear 1C1,1C2 and be the clockwise direction rotation, at this moment, because of two transmission gear 1C1, the 1C2 of one-level driving gear set 1C are that unilateral bearing 1C11, the 1C21 of cw transmission is engaged in respectively on first and second transmission shaft 1S1, the 1S2 with wheel to axle all, one, two transmission shaft 1S1,1S2 are rotated all in a clockwise direction; Because of little, big transmission gear 1D1, the 1D2 of secondary driving gear set 1D are that unilateral bearing 1D11, the 1D21 of cw transmission is engaged on first and second transmission shaft 1S1, the 1S2 with axle to wheel all, little, big transmission gear 1D1,1D2 that secondary driving gear set 1D is meshed rotate in a clockwise direction, thereby make secondary driving gear set 1D produce locking phenomenon and can't rotate, so when electric carrier places slope and motor static, can prevent the effect that electric carrier is sliding backward.
Though the auto-lock function of above-mentioned secondary driving gear set and having prevents the effect that electric carrier is sliding backward, when move electric carrier with the manpower desire wheel 1W is retreated when obtaining preferable mobile effect, can make wheel 1W can't retreat because of self-locking.At this moment, between the left half axle 1S31 of power take-off shaft 1S3 of the present invention or right axle shaft 1S32 and wheel 1W, engage with simple clutch structure 1E, break away from and be free rotation state so that wheel 1W and left half axle 1S31 or right axle shaft 1S32 are temporary transient, to separate the problem that must not retreat.
