Abstract
The utility model relates to a full gear wheel transmission device for a bicycle without a chain, which is mainly composed of a drive gear wheel, a big auxiliary gear wheel, a small auxiliary gear wheel, a free wheel, and an additional gear wheel of the free wheel. Because of two-stage variable speed and the omission of a chain of an existing bicycle, the utility model has the characteristics of simple structure, safe running, labor saving, etc. The full gear wheel transmission device for a bicycle without a chain can be used on bicycles, tricycles, and various manpower mechanical transmission devices.
Description
The utility model is a kind of Chainless bicycle all-gear system, is used for existing two-wheeled cycle with the transmission of chain biography fluted disc, tricycle, and the repacking of other manual machines.
Existing transmission mechanism of bicycle mainly is that manpower steps the toe clip active toothed disk, the fluted disc driving chain, and chain drives flywheel, to drive wheel, the main deficiency of this kind transmission device is that chain elongates easily in use, disconnected button and fall chain, results in hand cramps to the rider.
The purpose of this utility model provides a kind of Chainless bicycle all-gear system to overcome the existing in prior technology deficiency.
The utility model realizes that by following approach the bicycle all-gear system is made up of pedal, driving gear, equipment gear, flywheel, flywheel additional gear and vehicle frame; Pedal, driving gear and flywheel are all installed on the same axletree, flywheel is that existing standard is flown after axle removes external tooth, and an additional gear is fixed with screw thread between the two, flywheel itself is installed in the brake hub of existing bicycle quick, between wheel hub and the axletree bearing is housed.Equipment gear is made up of a big gear wheel and a miniature gears, fixedly on the vehicle frame, between gear and the minor axis bearing is housed with nut by a minor axis.
Figure (1) is the cutaway view of bicycle all-gear system.
Figure (2) is the lateral plan of bicycle all-gear system.
(1), (2) elaborate to embodiment of the present utility model in conjunction with the accompanying drawings.
The transmission of this device is finished like this, manpower steps pedal (1) and then drives axletree (10) and driving gear (13) rotation, driving gear (13) again with auxiliary miniature gears (15) interlock mutually, because auxiliary miniature gears (15) and auxiliary big gear wheel (4) are associated in together, so driving auxiliary big gear wheel (4) again rotates, auxiliary big gear wheel (4) again with flywheel additional gear (7) interlock mutually, drive flywheel (8) again, because flywheel (8) is fixed on the wheel hub (11), between flywheel (8) and the wheel hub is one-way movement, so can drive wheel.This driving device is process two-stage speed change in operational process, to improve its revolution ratio.First order speed change is to drive auxiliary miniature gears (15) by driving gear (13) to finish.Second stage speed change is to drive flywheel additional gear (7) again by auxiliary big gear wheel (4) to finish.Because this device is al-gear drive, the energy loss ratio chain gear is little, so ride laborsavingly, and can not fall chain again, and the accident of threading off and so on has improved the safety and the reliability that use.Outside the technical characterictic described in the utility model, be those skilled in the art's known technology.This device can be installed in existing bicycle, on the three-wheel vehicle, also can be used for the transmission of other manual machines.
Claims (4)
1, a kind of Chainless bicycle all-gear system, it comprises driving gear, equipment gear and flywheel additional gear, it is characterized in that: the mutual interlock transmission of driving gear, equipment gear and flywheel additional gear.
2, bicycle all-gear system according to claim 1, it is characterized in that: gear and flywheel are installed on the same axletree.
3, driving device according to claim 1 is characterized in that: additional gear on the standard flywheel, to fix with screw thread between the two, and flywheel is installed in the bicycle brake wheel hub.
4, driving device according to claim 1 is characterized in that equipment gear is made up of a big gear wheel and a miniature gears, is fixed on the vehicle frame with nut by minor axis.
