Embodiment
Please refer to Fig. 1 to shown in Figure 3, the utility model provides a kind of power differential design 1, and it comprises that one group of stand 11, a motor 12, a driving gear 13, a differential assembly 14 and two transmission shafts 15 form.
At first, the group stand 11 the shape that is shaped as hollow cube, yet the group stand 11 shape do not limited, in the group stand 11 inside be provided with group-connecting groove 111, and in the group stand 11 both sides be provided with the perforation 112 that runs through, again in the group stand 11 the bottom side form a through hole 113.
The below of group stand 11 then is a motor 12, and motor 12 can provide the power resources of power differential design 1.One end of motor 12 arranges a power gear 121, and power gear 121 wore through hole 113 and was arranged in group-connecting groove 111.Side in group-connecting groove 111 arranges a driving gear 13, and the central authorities of driving gear 13 axis hole 131 that is shaped, and with the perforation 112 corresponding to group stand 11, and power gear 121 and driving gear 13 are for being meshing with each other.Therefore, when motor 12 turns round, can make this power gear 121 rotate, and power gear 121 can drive the rotation of driving gear 13 when rotating, to reach the effect of input power.
In more detail, driving gear 13 is in arranging an end gear 142 near a side of planetary pinion 141, and end gear 142 is meshing with each other with the planetary pinion 141 of both sides up and down.Wherein a transmission shaft 15 wore the group perforation 112 of stand 11 and the axis hole 131 of driving gear 13, and then was connected on this end gear 142, and pad 151 can be set with as spacing function on transmission shaft 15.Because transmission shaft 15 is connected on the driving gear 13 mutually, so transmission shaft 15 can rotate with the running of driving gear 13.
Opposite side in group-connecting groove 111 arranges an end gear 142, and this end gear 142 is the end gear 142 that correspond on the driving gear 13.The central authorities of this end gear 142 are worn and mistake by a transmission shaft 15, and this transmission shaft 15 also wore the perforation 112 of organizing stand 11 opposite sides, extended outside the group stand 11.On the transmission shaft 15 and pad 151 can be set, pad 151 is in order to as spacing function.
Two planetary pinions 141 are positioned at the both sides up and down of group-connecting groove 111, and present in correspondence with each other kenel, wear connection with an axostylus axostyle 1411 again between two planetary pinions 141, axostylus axostyle 1411 is perpendicular to transmission shaft 15, and then allow two planetary pinions 141 be able between two end gear 142, and two planetary pinions 141 are meshing with each other with the end gear 142 of both sides respectively.Therefore, when the end gear 142 of an end is rotated, can make two planetary pinions 141 do corresponding rotation, and then the end gear 142 of the drive the other end is rotated.
In addition, in a peripheral sheathed goblet 143 of two end gear 142 and two planetary pinions 141, goblet 143 also is socketed on the driving gear 13, and goblet 143 can be the shape of hollow circular cylinder.Both sides in goblet 143 are offered perforate 1431 respectively, can extend from the perforate 1431 of goblet 143 so that wear the axostylus axostyle 1411 of planetary pinion 141.
Therefore, when motor 12 runnings, by power gear 121 power is transferred on the driving gear 13, to drive the rotation of driving gear 13.This moment is identical as the suffered rotational impedance power of the transmission shaft 15 of both sides, and then the end gear 142 of both sides presents synchronous rotation, and the rotating speed of transmission shaft 15 is identical.When the suffered rotational impedance power of the transmission shaft 15 of both sides not simultaneously, the planetary pinion 141 of both sides can cooperate the end gear 142 of both sides to present relative to engagement to rotate up and down, so that the rotating speed difference of transmission shaft 15.
Please refer to Fig. 1, Fig. 3 and shown in Figure 4, the utility model provides a kind of electrically driven truck that uses the power differential design in addition, and it comprises a go-cart 2, a power differential design 1 and a power supply unit 3.
In this embodiment power differential design 1 of the present utility model is installed in the go-cart 2, and install power supply unit 3 additional, power supply unit 3 provides the electric power of the motor 12 of power differential design 1, so that go-cart 2 is advanced and is turned, power differential design 1 is same as the previously described embodiments, repeats no more in this.
Go-cart 2 of the present utility model as shown in Figure 4, has a wheel unit 21 and grips unit 22.Wheel unit 21 is located at the bottom of go-cart 2, wheel unit 21 has first wheels 211 and second wheels 212, the quantity of set wheel is all two in first wheels 211 and second wheels 212, the wheel 2111 of first wheels 211 can be directional wheel, and the wheel 2121 of second wheels 212 can be movable wheel.Described gripping unit 22 is arranged at a side of go-cart 2, specifically, grips the top position that unit 22 is positioned at first wheels 211.Yet the gripping unit 22 of present embodiment can be according to the demand of practical application and the mode of variation configuration, and in other words, the utility model is not restricted to this.In addition, more comprise in the go-cart 2 braking device 23 is set, so that go-cart 2 has the function of brake.
Wherein, power differential design 1 is installed in first wheels 211, also is that power supply unit 3 is arranged in the go-cart 2 between two wheels 2111 of first wheels 211, and power supply unit 3 provides the power source of power differential design 1, makes motor 12 to turn round.Two transmission shafts 15 of power differential design 1 are coupling respectively on two wheels 2111 of first wheels 211, by the running of motor 12, so that go-cart 2 can have the function of advancing and turning.
Generally, the electrically driven truck that uses the power differential design is in straight ahead or retreat when advancing, because speed is not poor between the transmission shaft 15 of both sides, for power differential design 1, the end gear 142 of both sides presents synchronous revolution, make this up and down the planetary pinion 141 of both sides can not produce spinning motion or the rotation that is meshing with each other.Also namely two planetary pinions 141 and two transmission shafts 15, driving gear 13, two end gear 142 and goblet 143 etc. present common rotation, so differential assembly 14 can't produce any effect.
Yet, when the electrically driven truck that uses the power differential design turned to when curved, for power differential design 1, because the rotation distance difference that the wheel 2111 of and arranged on left and right sides is required, cause the both sides wheel shaft rotating speed on the wheel 2111 of and arranged on left and right sides inconsistent, and produce speed discrepancy, this moment of the planetary pinion 141 of the both sides rotation that can produce different rotating speeds up and down, the planetary pinion 141 of both sides and cooperate the end gear 142 of both sides to be relative to engagement to rotate up and down.And this power can transfer on the little transmission shaft of rotational impedance power 15, makes the wheel 2111 of its linking can be assigned to bigger torsion and wheel speed, thus can reach differential action, so that the electrically driven truck of this use power differential design can turn to smoothly.
In sum, the electrically driven truck of use power differential design of the present utility model can allow convenient promotion of user advance, and owing to have power differential design 1, can make go-cart have the function of turning.Therefore operate the electrically driven truck of use power differential design of the present utility model, not only have the labour-saving effect, and unheavy flexibly in the operation.
Just the above only is preferred embodiment of the present utility model; non-ly be intended to limit to scope of patent protection of the present utility model; so the equivalence of using the utility model specification and graphic content to do such as changes; all in like manner all be contained in claims protection domain of the present utility model, close and give Chen Ming.
