Description
Technical field
The utility model provides a kind of transmission of vehicle, especially a kind of unpowered vehicle transmission system.
Background technology
At present, the unpowered vehicle especially transmission system kind of bicycle is a lot, but all there are some shortcomings in it, and short as speed change difficulty, life-span, maintenance capacity is big, does not use light etc.Unpowered vehicle is the vehicle of a kind of safety, economy, body-building and environmental protection, and improving its gearshift performance in traveling process is a significant thing of benefiting the nation and the people.
Summary of the invention
The purpose of this utility model is to improve deficiency of the prior art, a kind of compact conformation is provided, is easy to variable speed operation, comformability is strong, sturdy and durable and unpowered vehicle transmission system that maintenance capacity is little.
The purpose of this utility model is achieved in that
The unpowered vehicle transmission system that the utility model provides comprises a casing, in this casing, be provided with a main shaft rotationally, on this main shaft, set firmly at least two diameters gear different with the number of teeth, in addition, side on this main shaft is arranged with a sleeve, on this sleeve, set firmly Jie's gear, be provided with bearing arrangement between an end of described main shaft and an end of this casing and described sleeve and this casing, between described main shaft and sleeve, also preferably be provided with bearing arrangement; In this casing, also be provided with a countershaft rotationally, be meshed being installed with Jie's gear that sets firmly on the sleeve of Jie's gear and described main shaft on this countershaft, on this countershaft, also be provided with slide teeth wheels, this gear cluster has at least two gears to form, its can by sliding on this countershaft with set firmly with this main shaft on gear mesh; Be installed with a hinge wheel stretching out on the end outside this casing of this sleeve that is sheathed on described main shaft; Be provided with the slip shift fork on the slide teeth wheels that are provided with on the described countershaft, be provided with the sliding tray that slides for this slip shift fork on described casing, described slip shift fork is by stretching out outside this casing in this sliding tray.
In use, this transmission system is fixed on the front-wheel and the vehicle frame in the middle of the trailing wheel of unpowered vehicle, set firmly the pedal thigh in two ends of stretching out the main shaft outside this casing, the hinge wheel that is set on this sleeve links together by messenger chain and the minor sprocket of being located on the rear vehicle shaft, a fixed gear wheel engagement on gear in the slide teeth wheels and the main shaft, scrunch pedal, main shaft is rotated, countershaft also rotates with a kind of speed with main shaft, Jie's gear on the countershaft is passed to power on this sleeve, hinge wheel is rotated, car is advanced thereby drive the rear vehicle shaft rotation.When handling described slip shift fork, make when the another one diameter fixed gear wheel different with the number of teeth meshes on slide teeth wheels and the main shaft on the countershaft, this hinge wheel will obtain another kind of rotating speed.This transmission system can be realized the multiple change of the gait of march of car easily.
In order to make this transmission system have better effect, more laborsaving, the length of the pedal thigh that matches in use is preferably 180～200mm, length than existing thigh 170mm approximately increases by 10～20%, thus, the needs that can adapt to the high, medium and low speed that this transmission system provides better, make device this transmission system car ride not painstaking.
The unpowered vehicle transmission system that the utility model provides is the drive mechanism of straight gear between parallel shafts by mechanically very common drive mechanism, overlapping axle construction cleverly by design makes this transmission system structure very simple and compact, use also easily, can provide multiple speed ratio to car.In addition, because it is simple in structure, make its comformability stronger, service life is also long, and for ease of maintenaince, maintenance load is also smaller.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
The structural representation of the transmission system that Fig. 1 provides for the utility model;
The main axle structure scheme drawing of the transmission system that Fig. 2 provides for the utility model.
The specific embodiment
As shown in Figure 1, the unpowered vehicle transmission system 2 that the utility model provides comprises a casing 1, is provided with a main shaft 3 in casing 1, sets firmly three gears that diameter is different with the number of teeth on main shaft 3: gear 6, gear 7 and gear 8.
Also be provided with a countershaft 4 rotationally in casing 1, be provided with slide teeth wheels on countershaft 4, this gear cluster is made up of three gears: gear 11, gear 12 and gear 13, it can be by sliding on countershaft 4 and the gear mesh that is fixedly arranged on the main shaft 3.
In addition, the side on main shaft 3 is arranged with a sleeve 31, sets firmly Jie's gear 9 on sleeve 31, is meshed being installed with Jie's gear 9 that sets firmly on the sleeve 31 of Jie's gear 10 and main shaft 3 on the countershaft 4.Be provided with bearing arrangement between one end of main shaft 3 and the casing 1 and between an end of sleeve 31 and the casing 1, between main shaft and sleeve, also preferably be provided with bearing arrangement.It is standard form that described bearing preferably changes existing bulk type, uses the antifriction-bearing box of standard, can provide the durability of this device effectively like this, and maintenance capacity is further reduced.
In order to make the more compact structure of this speed reduction gearing, volume is little, and it is 1.5～2 gear that employed gear is preferably modulus.
Be installed with a hinge wheel 5 stretching out on the end outside the casing 1 of the sleeve 31 that is sheathed on main shaft 3; Be provided with slip shift fork (not shown) on the slide teeth wheels that are provided with on the countershaft 4, be provided with the sliding tray 16 that slides for this slip shift fork on casing 1, this slip shift fork is by stretching out outside casing 1 in the sliding tray 16.
