The present invention proposes a kind of carbon-free trolley shift fork synchronizer shift speed change mechanism.
Fig. 1 to Fig. 2, carbon-free trolley shift fork synchronizer shift speed change mechanism of the invention are referred to, including is installed on carbon-free
Dolly rear portion and be parallel to each other front axle 6 and rear axle 4, be fixedly connected on carbon-free trolley rear portion and with control circuit electrically connect after
Steering wheel 10 is taken turns, and the front axle 6 of the present embodiment can be moved axially along its center axis, the middle part of rear axle 4 is fixedly connected with
Slope backgear 2 and level road little gear 3, the middle part of front axle 6 are fixedly connected with upward slope front gear that can be with the engaged transmission of upward slope backgear 2
9 and the level road gear wheel 7 with the engaged transmission of level road little gear 3.The top of trailing wheel steering wheel 10 of the present invention rotates output end and water
The flat middle part of first connecting rod 11 set is fixedly linked, and one end of first connecting rod 11 is connected to form rotation with one end of second connecting rod 12
Pair, the other end of second connecting rod 12 is connected to form revolute pair with one end of third connecting rod 13 parallel to front axle 6, third connecting rod 13
The other end is fixedly connected with the groove 81 of the outer peripheral face of shift fork 8 between the insertion upward slope of push pedal 14 front gear 9 and level road gear wheel 7
It is interior.The shift fork 8 of the present invention is placed on the outer peripheral face of front axle 6 and axially moved along front axle 6, and shift fork 8 is toward upward slope front gear 9
The shift fork tooth 82 of pluggable upward slope front gear 9 and the internal axial hole of level road gear wheel 7 is equipped with the side of level road gear wheel 7.
Specifically, in the embodiment of the present invention, the gearratio between upward slope front gear 9 and upward slope backgear 2 is 1:1, level road
Gearratio between gear wheel 7 and level road little gear 3 is 3:1, the present embodiment controls the circuit to be single chip circuit, and in this hair
In bright other embodiment, it is PLC circuit to control circuit.
In the embodiment of the present invention, carbon-free trolley is declined by weight, and the fixed pulley group of carbon-free trolley passes through drag wire opposing connection
Spool 5 is pulled and so that reel 5 is rotated.Because reel 5 is closed with front axle 6 to be fixed in the embodiment of the present invention
System, thus reel 5 be pulled line pull rotated after, front axle 6 also by reel drive and rotated.
When carbon-free trolley needs to move ahead in level road, the single chip circuit of circuit is controlled to export PWM ripples to trailing wheel steering wheel 10,
So that trailing wheel steering wheel 10 rotates a certain angle, so that the first connecting rod 11 at the top of trailing wheel steering wheel 10 rotates,
And first connecting rod 11 affects second connecting rod 12 to be swung accordingly, and second connecting rod 12 pulls third connecting rod 13 along front axle 6
Axially it is moved forward or rearward, and finally make it that the push rod 14 in insertion shift fork 8 is moved forward or rearward, so that
Obtain in the insertion upward slope of shift fork tooth 82 front gear 9 or the internal axial hole of level road gear wheel 7 of shift fork 8, so as to promote front axle 6 to carry out phase
The movement answered, and finally cause only upward slope front gear 9 and the intermeshing transmission of upward slope backgear 2, the wherein He of upward slope front gear 9
Engaged transmission ratio between upward slope backgear 2 is 1:1.Because carbon-free trolley is when level road is travelled, it is not necessary to by producing
Larger torque is climbed, and 1:1 engaged transmission than can be achieved it is effective be driven and cause carbon-free trolley wheeled farther away from
From.
When carbon-free trolley needs in uphill way move ahead, control the single chip circuit of circuit defeated to trailing wheel steering wheel 10
Go out PWM ripples, so that trailing wheel steering wheel 10 rotates a certain angle, so that the first connecting rod 11 at the top of trailing wheel steering wheel 10 is sent out
It is raw to rotate, and first connecting rod 11 affects second connecting rod 12 to be swung accordingly, and the drawing third connecting rod 13 of second connecting rod 12 edge
Front axle 6 to be axially moved forward or rearward, and finally make it that the push rod 14 in insertion shift fork 8 is moved forward or backward
It is dynamic, so that in the insertion upward slope of shift fork tooth 82 front gear 9 or the internal axial hole of level road gear wheel 7 of shift fork 8, so that before promoting
Axle 6 is moved accordingly, and finally to be intermeshed transmission only between level road gear wheel 7 and level road little gear 3, wherein
Engaged transmission ratio between level road gear wheel 7 and level road little gear 3 is 3:1.Because carbon-free trolley is needed in uphill way traveling
When, it is necessary to climbed by producing larger torque, 3:1 engaged transmission than effective transmission can be achieved so that
Carbon-free trolley is smoothly climbed.
When carbon-free trolley needs in descending section move ahead, control the single chip circuit of circuit defeated to trailing wheel steering wheel 10
Go out PWM ripples, so that trailing wheel steering wheel 10 rotates a certain angle, so that the first connecting rod 11 at the top of trailing wheel steering wheel 10 is sent out
It is raw to rotate, and first connecting rod 11 affects second connecting rod 12 to be swung accordingly, and the drawing third connecting rod 13 of second connecting rod 12 edge
Front axle 6 to be axially moved forward or rearward, and finally make it that the push rod 14 in insertion shift fork 8 is moved forward or backward
It is dynamic, so that in the insertion upward slope of shift fork tooth 82 front gear 9 or the internal axial hole of level road gear wheel 7 of shift fork 8, so that before promoting
Axle 6 is moved accordingly, and finally to be intermeshed between upward slope front gear 9 and upward slope backgear 2, while level road canine tooth
Also it is intermeshing between wheel 7 and level road little gear 3.Because upward slope backgear 2 and level road little gear 3 are both secured to rear axle 4, and
Upward slope front gear 9 and level road gear wheel 7 are both secured on front axle 6, when engagement between upward slope front gear 9 and upward slope backgear 2, and
And after level road gear wheel 7 and level road little gear 3 are intermeshed, are fixed and can not be rotated between front axle 6 and rear axle 4, because
For carbon-free trolley by trailing wheel and it is domatic between friction cause carbon-free trolley along domatic slide downward pass through to
Under slope.
Relative to prior art, the carbon-free trolley of the embodiment of the present invention passes through between upward slope front gear 9 and upward slope backgear 2
Engagement walks in level road section, or is engaged by level road gear wheel 7 with level road little gear 3 and walk in uphill way, or by upper
Engaged between slope front gear 9 and upward slope backgear 2 and level road gear wheel 7 engage with level road little gear 3 and walks in descending section,
So that the carbon-free trolley of the present embodiment is adaptable to different sections of road so that carbon-free trolley has more extensive answer
Use scope.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this
Under the design of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/it is used in indirectly
He is included in the scope of patent protection of the present invention related technical field.
