Description
Technical field
The invention belongs to vehicles transmission field, more particularly, to a kind of transmission device and the card with the transmission device
Fourth car.
Background technology
Perambulator be it is one main kind of among toy for children, including child's bicycle, children trolley, baby walker,
Child's tricycle, the major class of children's kart five.The range of age that kart is applicable children is 4~8 years old, with reference to children's when choosing
Age and stature height, select suitably sized.
The kind of drive of general kart is driving-chain or belt, because child is active and curiosity is strong, once handle
It is hardly imaginable to put in consequence in the wheel disc of rotation, so the transmission device of driving-chain or belt should all add protective cover to make it can not
Touch, while will be in the case of without using instrument, the protective cover of driving-chain or belt can not be removed so that child is not
It can take or remove easily protective cover, while clockwork spring driving, battery power, inertial drive or other power-driven machines of kart apart
Structure should be closed, should not expose accessible sharpened edge, pointed tip or other weigh finger or other positions of body wounded
Hazardous components, and the child's bicycle for not meeting this requirement completely is usually seen in some small commodity markets.
Foot-operated machinery, which rides kart, needs a brake apparatus, typically when carrying out braking test, starts system
The distance of dynamic device toy movement not should be greater than 5 centimetres；Rider toy more than or equal to 30 kilograms, it should have braking and locking dress
Put, brake apparatus is mainly the parking brake that is adapted with drive, and parking brake is due to needing larger power just to hold with a firm grip, due to children
Strength it is smaller, the situation for stopping and not living car or can not braking in time may be produced during brake, simultaneously because parking brake is using brake
Piece is held tightly to rotating wheel to brake, and after certain usage time was entered, brake block subtracts with increasing for Rubbing number
Few coefficient of friction, so that brake block needs the longer time to be held tightly to rotating wheel so that braking time is elongated,
Certain potential safety hazard easily be present, harm is brought to children.
Foot-operated kart is to be rubbed by the fierceness between brake block and rotating wheel in completion in the prior art, and when card
Steam be present on wheel so that one layer of water between brake block and rotating wheel be present when moisture is larger or rainy day travels in fourth car
Film, just as having smeared lubricating oil so that the frictional force between brake block and rotating wheel reduces, and uncontrollable kart stops
Only, simultaneously because there is the presence of protective cover so that the steam in protective cover is also not easy to shed, and potential safety hazard be present.
In the prior art also there is extremely winged theory is utilized, without unidirectional freewheel so that wheel is eternal with pedal
In linkage status, that is to say, that rear flywheel is fixed on colored hub and can not rotated freely, and rear flywheel passes through chain and chain wheel phase
Connection, acting on pedal power can be by tooth than acting on trailing wheel after amplification so that pedal can not slide shape under remains stationary
State, when this mode of braking is present on kart, it is necessary to step on pedal all the time, this is for children, due to children's
Muscle power is limited, is not suitable for children.
The content of the invention
The present invention be in order to overcome it is above-mentioned in the prior art the defects of, there is provided a kind of simple in construction, brake is convenient, safely may be used
The transmission device leaned on and the kart with the transmission device.
In order to reach object above, the technical solution adopted in the present invention is：A kind of transmission device and with the transmission dress
The kart put, including screw rod, rotation input component and rotary output member；It is defeated that rotation can be transferred to rotation by the rotation input component
Go out part, and rotate and freewheel clutch is provided between input component and rotary output member, rotary output member is fixed with freewheel clutch to be connected
Connect, the freewheel clutch and rotation input component are connected with screw rod, wherein rotation input component is located at freewheel clutch
One end.
