Abstract
The utility model relates to a composite type multi-gear derailleur which is used for the technical fields of vehicles, agricultural machines, engineering machines and machine tools, comprising a main gear shifting mechanism and an auxiliary gear shifting mechanism. The main gear shifting mechanism is the prior technology. The output end of a main intermediate shaft and the input end of the auxiliary gear shifting mechanism are connected by a box coupling to form the technology. The auxiliary gear shifting mechanism(two) essentially consists of an auxiliary shifting handle and a drawing fork positioning interlocking mechanism assembly which connects with the auxiliary shifting handle; the middle is provided with three parallel axles of an auxiliary gear shifting mechanism, a transition wheel arbor, a power output axis and a driving gear at every wheel. The utility model has the advantages of simple structure, low cost, high reliability, easy maintenance, energy saving, multi gears and adaptability of different road conditions and road surfaces.
Description
The utility model relates to a kind of speed change gearing that is used for vehicle, agricultural machinery, construction machinery and equipment and lathe, especially a kind of compound type multi-speed gear box.
Existing change-speed box, complex structure, gear is few, repairs and keep in repair extremely inconvenience, as is used in the occasion of vehicle, and road conditions, the road surface that can not adapt under the various conditions are exercised requirement, and are not met energy-conservation requirement.
For overcoming the deficiencies in the prior art, the utility model provides a kind of compound type multi-speed gear box, the gear of change-speed box is increased, to adapt to various different road conditions, the road surface speed of a motor vehicle.Structure of the present utility model as shown in Figure 1, it is made of main speed-changing mechanism (I) and secondary speed-changing mechanism (II); (I) part is existing four-speed gear shift box technology, comprise that driving fork by gear shifting handle (5) through the fork axle carries out different speed ratio gears and nibble and join, and the mechanism that realizes fork shaft location and gear interlocking, mainly by secondary gear change hand lever (1) and connected fork location mutual interlocking gear assembly (17); Below it three axles parallel to each other, be secondary tween drive shaft (2), transition wheel axle (19), power output shaft (8), can be along the cliding gear (11) of secondary tween drive shaft (2) slip, (13), reverse gear cliding gear (8), can and set reverse gearwheel (10) on power output shaft (18) around the transition wheel (9) of axle (19) rotation, expand shelves big gear wheel (12) at a high speed, low speed expansion shelves big gear wheel (14), above-mentioned (2) and (18) two axle two ends all are bearing in respectively on the bearing (16) of casing (6) sidewall, transition wheel axle (19) one ends are fixed on the casing (6), power is by power input shaft (7) input main speed-changing mechanism (I), and the mouth by the main tween drive shaft (15) in (I) links by the input end of thimble coupling (4) with secondary speed-changing mechanism (II) again.The utility model has following beneficial effect compared with the prior art.1. the shelves number is many, can adapt to different road conditions, road surface and need of work; 2. simple in structure, from heavy and light, cost is low; 3. reliability height, maintenance easily; 4. save the energy, the efficient height.Can be applied to the change speed gear box of vehicle, agricultural machinery, construction machinery and equipment, lathe.
Description of drawings:
Fig. 1 is a structural principle scheme drawing of the present utility model, expression the utility model is made of main speed-changing mechanism (I) and secondary speed-changing mechanism (II) among the figure, and two parts are linked with thimble coupling (4) by the mouth of the main tween drive shaft (15) of main speed-changing mechanism (1) and the input end of secondary speed-changing mechanism (II).
Embodiment:
Main transformer of the present utility model speed part, converter speed ratio can be with 1～4 grades, i.e. R
Main=4 secondary speed-change and gearshift handles (1) are by being clamped in fork (3) and fork shaft alignment mutual interlocking gear assembly (17) on the axle sleeve that links cliding gear (11) and (13), make sliding wheel (11) or (13) slide and gear (11) is meshed with (14) with (12) or gear (13) to the right and realize height two grades of speed ratios, i.e. R along secondary tween drive shaft (2)
Secondary=2; The attainable speed shelves R that always advances of major-minor two parts speed-changing mechanism
Advance=R
Main* R
Secondary=4 * 2=8 D Drive; In like manner, the utility model makes reverse gear cliding gear (8) and transition gear (9) engagement by handling secondary gear shifting handle (1) driving gear shift fork, thereby make the reversing of reverse gearwheel (10) and output shaft (18), combine with 4 grades of input speeds and can realize that 4 reverse gears are R from main speed-changing mechanism part (I) tween drive shaft (15)
Fall=4, therefore, the utility model can be realized total gear shift number: R
Always=R
Advance+ R
Fall=12.
Claims (1)
