Abstract
A four-wheel or three-wheel motorbike used chain drive back crosspiece mechanism relates to a drive mechanism of the four-wheel or three-wheel motorbike, belonging to the vehicle manufacturing technological art, mainly comprising a back crosspiece gear unit, a drive gear, an output gear, a drive chain wheel and a support shaft, wherein the drive gear is equipped on the drive shaft end of a forward and a backward crosspiece gear unit and is engaged with an output gear, the output gear is equipped on the support shaft and can be positioned on the left or the right of a back crosspiece box, the whole outer portion is embraced by the box body, and the drive chain wheel is equipped outside the output gear. According to the design of a couple of engaged drive gear and the output gear and one support shaft and the drive chain wheel on the end of the back crosspiece gear unit, the utility model realizes the purpose of chain drive typed back crosspiece, and has the advantages of reasonable structure, reliable performance, safe usage, easy manufacturing and the like.
Description
(1) technical field
The utility model relates to the transmission device of a kind of four-wheel or motor-tricycle, belongs to self-propelled vehicle manufacturing technology field.
(2) background technology
Existing four-wheel or the motor-tricycle that uses chain gear, great majority do not have reverse gear apparatus, therefore can't move backward, and this causes inconvenience to the driver.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, and a kind of rational in infrastructure, dependable performance, four-wheel or motor tricycle chain transmission type reverse gear mechanism safe in utilization are provided.
The utility model is finished by following technical measures.
This chain transmission type reverse gear mechanism mainly is made up of reverse gearwheel combination, transmission gear, output gear, driving chain wheel and pivot shaft, wherein, at the terminal transmission gear of installing of the transmission shaft that advances the reverse gearwheel combination, and mesh with output gear, output gear is installed on the pivot shaft, can place the left side or the right side of reverse gear case, whole outside has casing to contain, and driving chain wheel is installed in the outside of output gear.
The combination of described reverse gearwheel by input gear, advance a grade gear, reverse gearwheel, clutch ratchet, transmission shaft, shift fork and form.
The utility model is realized the purpose of chain transmission type reverse gear by at a pair of intermeshing transmission gear of tip designs of existing reverse gearwheel combination and output gear and pivot shaft, driving chain wheel.During use, driving chain wheel is equipped with chain and drives trailing wheel and rotates, and reverse gearwheel combination input gear is connected with the output shaft of spark ignition engine, and the clutch ratchet is connected with spline with transmission shaft, transmits the power of spark ignition engine.Like this, when shift fork was stirred the clutch ratchet and advanced a grade gear and combine, driving chain wheel just changeed, and car advances, otherwise, when shift fork is stirred the clutch ratchet and is combined with reverse gearwheel, the driving chain wheel counter-rotating, car then retreats.The utlity model has rational in infrastructure, dependable performance, safe in utilization, make advantages such as simple.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, 1, the reverse gear box body, 2, input gear, 3, transmission shaft, 4, advance a grade gear, 5, the clutch ratchet, 6, reverse gearwheel, 7, shift fork, 8, transmission gear, 9, output gear, 10, pivot shaft, 11, driving chain wheel, 12, spark ignition engine.
(5) specific embodiment
Embodiment: structure as shown in drawings, form by reverse gearwheel combination, transmission gear 8, output gear 9, driving chain wheel 11 and pivot shaft 10, reverse gearwheel combination by input gear 2, advance grade gear 4, reverse gearwheel 6, clutch ratchet 5, transmission shaft 3, shift fork 7 and form reverse gearwheel and make up.End at transmission shaft 3 is meshed by dress transmission gear 8 and with output gear 9, passes pivot shaft 9 in the middle of output gear 8, at an end of pivot shaft 10 driving chain wheel 11 is installed, and whole outside is contained by casing 1.During use, the output shaft of spark ignition engine 12 and input gear 2 link together, input gear 2 again with advance grade gear 4 and reverse gearwheel 6 meshes together, transmission shaft 3 passes wherein, have spline on the clutch ratchet 5, with the transmission shaft 3 that the has spline transfer torque that is connected as a single entity.Advance on grade gear 4 and the reverse gearwheel 6 and all have the ratchet groove, be meshed with the ratchet of projection on the clutch ratchet 5, when chaufeur is stirred shift fork 7, by clutch ratchet 5 and the mutual action that advances grade gear 4 or reverse gearwheel 6, and then drive transmission gear 8 and output gear 9 and driving chain wheel 10, realize advancing or retreating.
Claims (2)
1, a kind of four-wheel or motor tricycle chain transmission type reverse gear mechanism, it is characterized in that, mainly form by reverse gearwheel combination, transmission gear, output gear, driving chain wheel and pivot shaft, wherein, mesh at the transmission shaft terminal installation transmission gear of reverse gearwheel combination and with output gear, output gear is installed on the pivot shaft, can place the left side or the right side of reverse gear case, whole outside has casing to contain, and driving chain wheel is installed in the outside of output gear.
2, four-wheel according to claim 1 or motor tricycle chain transmission type reverse gear mechanism is characterized in that, reverse gearwheel combination by reverse gear case, input gear, advance a grade gear, reverse gearwheel, clutch ratchet, transmission shaft, shift fork and form.
