Abstract

The invention relates to a gear speed transformation device which is mainly composed of a transmission gear, a rear crankset, a crankset shaft, a transmission shaft, a transmission shaft bracket, a reset spring, a hitch, a slideway, a transmission shaft shrinkage hole, an inserting shaft, a shift cable bracket, a shift cable hole and a front crankset, wherein the transmission gear is meshed with the front crankset and the rear crankset, and the front crankset drives the transmission shaft to transmit power to the rear crankset; and a shift cable controls the hitch at different positions of the slideway via the shift cable hole and the reset spring to control the transmission shaft so as to further control the transmission gear and different stages of drum-shaped gears of the front crankset and the rear crankset to be meshed, so that shaft driven speed transformation is realized. The gear speed transformation device has the advantages of simple structure, high convenience in operation and high economy and efficiency.

Description

A kind of speed change gear
Technical field
The invention belongs to speed change gear field, is related to a kind of speed change gear.
Background technology
Vehicle speed variation is inevitable problem in daily life, and existing speed change gear mainly utilizes planetary gear Speed change gear, by arranging the different gear of multiple sizes in speed change gear speed change is realized.For example:Chinese invention is special Profit, combined type gear ring planetary transmission, application number CN201620363519.0;Chinese invention patent, puts in bicycle Double motor small teeth number difference planet gear speed change gear, application number CN201510155890.8.This kind of speed change gear complex structure, Involve great expense, the not only running to device causes very big pressure, once and parts damages of device are difficult to work, Service life is short.
The application is engaged with front chain wheel, rear chain wheel using travelling gear, drives power transmission shaft to transmit power by labial teeth disk To rear chain wheel;Hitch is controlled the diverse location in slideway for shift cable Jing speed change string holes and back-moving spring, so as to control power transmission shaft And then the engagement of the different level tubbiness gears of control travelling gear and front chain wheel, rear chain wheel is realizing axle transmission gear shift.Therefore, originally Application simple structure, easy to operate, economical and efficient.
The content of the invention
It is an object of the invention to provide a kind of speed change gear.
A kind of speed change gear, including it is travelling gear 1, rear chain wheel 2, chain wheel axle 3, power transmission shaft 4, drive axle support 5, multiple Position spring 6, hitch 7, slideway 8, power transmission shaft shrinkage hole 9, insertion axle 10, speed change line bracket 11, speed change string holes 12 and front chain wheel 13; Travelling gear 1, chain wheel axle 3, drive axle support 5, hitch 7, power transmission shaft shrinkage hole 9 and insertion axle 10 are set gradually on power transmission shaft 4, Wherein travelling gear 1, chain wheel axle 3, drive axle support 5, hitch 7 and power transmission shaft shrinkage hole 9 are respectively two, with respect to insertion axle 10 Symmetrical laying;Travelling gear 1, chain wheel axle 3 and drive axle support 5 are fixed on power transmission shaft 4, and drive axle support 5 is gear The support section of speed change gear;The two ends of slideway 8 are opposing parallel with power transmission shaft 4 by being fixed on two drive axle supports 5;It is sliding The two ends of road 8 arrange back-moving spring 6, middle setting speed change line bracket 11;Pass through back-moving spring 6 between drive axle support 5 and hitch 7 It is connected, hitch 7 is moveable, and slides on slideway 8, back-moving spring 6 is used for pulling power transmission shaft 4 to reset;Power transmission shaft shrinks Hole 9 is connected with insertion axle 10, can only axially opposing movement, it is impossible to relatively rotate;Speed change string holes 12 is set on speed change line bracket 11, Hitch 7 is controlled the diverse location in slideway 8 for shift cable Jing speed change string holes 12 and back-moving spring 6;2 points of front chain wheel 13 and rear chain wheel It is not fixed on two chain wheel axles 3, and is connected with the engagement of the travelling gear 1 at power transmission shaft two ends respectively.
When using, travelling gear is engaged with front chain wheel, rear chain wheel, drives power transmission shaft to transfer power to backteeth by labial teeth disk Disk;Hitch is controlled the diverse location in slideway for shift cable Jing speed change string holes and back-moving spring, so as to controlling power transmission shaft and then controlling The engagement of the different level tubbiness gears of travelling gear processed and front chain wheel, rear chain wheel, realizes axle transmission gear shift.
Beneficial effects of the present invention:The advantages of simple structure of this speed change gear, easy to operate, economical and efficient.
