Embodiment 1
As Fig. 1, Fig. 2, shown in Figure 3 be a kind of mode of execution of the utility model ratchet differential electric car speed changer, described ratchet differential electric car speed changer comprises casing 1, is provided with main shaft 2, driven shaft 5 and differential mechanism 11 in the casing 1.
Shown in Fig. 1, Fig. 2, described driven shaft 5 is provided with at least two driven gears 4, and driven gear 4 can rotate on driven shaft 5, and the diameter of each driven gear 4 is different.The corresponding driving gear 3 that is fixed with driven gear 4 engagement driving on the described main shaft 2.The utility model is provided with two driven gears 4 on driven shaft 5, be installed on the driven shaft 5 through driven gear back-up ring 19, and the diameter of each driven gear 4 on the driven shaft 5 reduces from the inside to the outside gradually.
After motor 26 energisings were rotated, the motor shaft tooth 22 of motor shaft 21 ends drove elementary reduction gear 23 and rotates, and rotated thereby drive main shaft 2.Two driving gears 3 of main shaft 2 rotate thereupon, with the also rotation thereupon of driven gear 4 of driving gear 3 engagements.
Be connected with adjustable lever 31 on the described movable part 8, the outer end that adjustable lever 31 stretches out casing 1 is connected with electromagnet 14, and the electromagnet 14 of the utility model is the function of two-way twitch and two-way maintenance location.
When electromagnet 14 energisings; Electromagnet 14 is pulled outwardly adjustable lever 31 and slider 8; When this moment, slider 8 left the ratchet 7 on driven gear 4 those fragment position of top gear on the driven shaft 5, it stuck up end and sticks up in the axis hole 6 into, its perk end perk and also snap in the internal tooth 16 of driven gear 4 of correspondence ratchet 7 under the effect of torsion spring 15; The driven gear 4 of top gear drives driven shaft 5 and rotates, and it is two retainings that driven shaft 5 driving differential mechanisms 11 rotate this moment with semiaxis 27.Through driving gear and the driven gear that many group sizes have nothing in common with each other is set; Come adjustment slide 8 position of 6 in axis hole through electromagnet 14; The perk end of the ratchet 7 on driven shaft 5 each sections is snapped in or break away from the internal tooth 16 of corresponding driven gear 4; Can make driven gear 4 combine to realize speed governing with driven shaft 5, thereby realize the rotating speed of multi-change speed adjusting differential mechanism 11.
Described driven gear 4 is provided with internal tooth 16, on sheathed this section driven shaft 5 of driven gear 4, is arranged with a pair of ratchet loose slot 10, is provided with ratchet 7 in the ratchet loose slot 10; Ratchet 7 can be in ratchet loose slot 10 along driven shaft 5 tilting radially; For making ratchet 7 be convenient to install, described driven shaft 5 is provided with ratchet axis hole 17, in ratchet axis hole 17, is provided with pawl axis 9; Described ratchet 7 is through on the pawl axis 9 with torsion spring 15, and ratchet 7 can rotate around pawl axis 9.Ratchet 7 is provided with and acts on the torsion spring 15 that makes the perk of one of which end on the driven shaft 5, and described driven shaft 5 is provided with torsion spring hole 24, and torsion spring 15 is through on the pawl axis 9, and torsion spring 15 1 ends are located in the torsion spring hole 24, and the other end is pressed on the ratchet 7.Under the normality situation, torsion spring 15 makes ratchet 7 perks one end be in the outside of driven shaft 5, and the other end is in the axis hole 6.When ratchet loose slot 10 is stuck up in ratchet 7 outer ends, may be stuck in the internal tooth 16 and and engage with internal tooth 16, driven gear 4 and driven shaft 5 are rotated together.When ratchet 7 outer ends were stuck up into ratchet loose slot 10, ratchet 7 separated with internal tooth 16, and then driven gear 4 just rotates around driven shaft 5.Ratchet 7 forms a ratchet snap-in structure with driven gear 4 like this, has unidirectional drive property.Be provided with slider 8 in the axis hole of described driven shaft 5, but jack-up ratchet 7 sticks up into end when slider 8 endwisely slips in axis hole 6.
Hence one can see that, comes adjustment slide 8 to control the interlock between driven gear 4 and the driven shaft 5 through electromagnet 14, can realize the adjusting of two-stage speed change.The rest may be inferred, a plurality of driving gears 3 is set just can realizes the multi-change speed adjusting with driven gear 4.
The power of motor 26 is transferred to final stage gear 13 and directly drives differential mechanism 11 after speed change; Be delivered to angular wheel 37 again; Drive left and right half gear 38; Differential gear 38 drive left and right sides semiaxis 27 and then driving wheel, when the vehicle straight-line travelling, differential mechanism 11 shells, angular wheel 37, the identical differential mechanism with the driving wheel rotating speed of left and right half gear 38 are not worked this moment.Work as Ackermann steer angle, wheel interior at one time distance of being walked in both sides does not wait, and the distance that foreign steamer moves is bigger than interior wheel; Because the left and right wheels stressing conditions changes, feedback is on differential gear 38, and this moment, differential mechanism was in work; Angular wheel 37, differential gear 38 produce rotation in revolution; Automatically increased the rotating speed of outer wheel, outer wheel is accelerated, interior wheel is slack-off and play the effect of differential.
Described each gear of the utility model also can be belt pulley or sprocket wheel, and engagement driving each other becomes belt or chain transmission, also can reach the technique effect of transmission joint.
