2, technical background

Gearbox is that the important structure of vehicle transmissions is formed, gearbox develop into today its structure and form also all of all kinds, but all in various degree have a defective, picture is more advanced hydraulic automatic transmission at present, its manufacturing process complexity, the price height, lock-up clutch has been pinned the power of motor 60%, cause than general speed changer excessive fuel consumption more than 20%, and can only be used on the petrol engine, diesel engine can't use, because its manufacturing process complexity, in a single day speed changer goes wrong and often is difficult to repair, and some advanced speed changers also are because price height etc. are former thereby can't promote the use of.

3, summary of the invention

The purpose of this utility model provides a kind of reasonable in design, simple in structure, low cost of manufacture, the saving energy, easy to operate stepless speed-changing gear box.

The purpose of this utility model realizes in the following manner, in gearbox casing, be provided with output shaft system according to diamond structure, high speed shaft system, reverse gear shaft system, lower velocity shaft system and tooth shaft coupling, output shaft system and high speed shaft system join, high speed shaft system and reverse gear shaft system join, reverse gear shaft system and lower velocity shaft system join, high speed shaft system, reverse gear shaft system and lower velocity shaft system join with the tooth shaft coupling respectively, an organic gear and two stepless gears of utilizing output shaft to fasten have level thereby formed three, (1+2) * (2+1) transmission mode of six stepless (six forward gear and three reverse gear).

Accompanying drawing 1 is the structural representation of stepless speed-changing gear box;

Accompanying drawing 2 is the layout structure schematic representation of each system of stepless speed-changing gear box;

4, description of drawings

Explain below with reference to Figure of description Stageless gear mission of the present utility model being done.

Stageless gear mission of the present utility model, its structure be by main shaft 1, driving gear 2, freewheel clutch 3, initiatively Gear 4, bearing 5, driving gear 6, automatic clutch 7, bearing 8, high speed shaft 9, driven gear 10, power clutch 11, power clutch 12, freewheel clutch 13, driven gear 14, driven gear 15, power clutch 16, driven tooth Wheel 17, reverse gear shaft 18, power clutch 19, driven gear 20, driven gear 21, slow-speed shaft 22, driven gear 23, Power clutch 24 and driven gear 25, tooth shaft coupling 26 and gearbox body 27 consist of the two ends of main shaft 1 and gearbox body 27 phases Connect, driving gear 2, freewheel clutch 3, driving gear 4, bearing 5, driving gear 6, automatic clutch 7 and bearing 8 are pressed Order from left to right is successively set on the main shaft 1, and the two ends of high speed shaft 9 and gearbox body 27 join, driven gear 10, Power clutch 11, power clutch 12, freewheel clutch 13, driven gear 14, driven gear 15, power clutch 16, driven gear 17 is successively set on the high speed shaft 9 two ends of reverse gear shaft 18 and gearbox body 27 by from left to right order Join, power clutch 19, driven gear 20, driven gear 21 are successively set on reverse gear shaft 18 by order from left to right On, the two ends of slow-speed shaft 22 and gearbox body 27 join, driven gear 23, power clutch 24 and driven gear 25 by from Left-to-right order is successively set on the slow-speed shaft 22.

5, mode of execution

Its processing and fabricating of stepless speed-changing gear box of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.All axles and gear are made the also available machine-tooled method manufacturing of bearing and various clutch with casting process and machine-tooled method.

Operate the mode that spreads that limit speed case power is described below by gear:

Driving gear 2 all meshes together with driven gear 23 with driven gear 20, driven gear 20 with driven gear 14, driven gear 15 with driven gear 14, driving gear 6 with driven gear 10, driving gear 4 at any time, but not necessarily through-put power is controlled their work by clutch and controller as required.

For example, when starting, deceleration descending or Emergency braking, manipulator dynamic clutch 11, power on the main shaft 1 is passed to high speed shaft 9 through driving gear 2, driven gear 10, if high speed shaft 9 rotating speeds meet the requirements, then power sends tooth shaft coupling 26 to by driven gear 17 under the control of power clutch 16, and tooth shaft coupling 26 drives each mechanism's work for power delivery each mechanism again.If rotating speed is undesirable, power is passed to lower velocity shaft 22 through driven gear 15, driven gear 20, driven gear 23 under the effect of each clutch, and power is passed to tooth shaft coupling 26 through driven gear 25 again.

When reversing gear, power is passed to reverse gear shaft 18 by high speed shaft through driven gear 15 and driven gear 20, and under the effect of controller, power sends tooth shaft coupling 26 to through driven gear 21.

The characteristics that stepless speed-changing gear box of the present utility model adopts organic speed change and stepless change to combine, utilize organic speed change to replace lock-up clutch, more than the fuel-efficient 40%-50% of original automatic transmission, more fuel-efficient more than 25% than organic speed change, the power that the organic transmission of gear spreads out of all is organic, the power that the inorganic transmission of gear spreads out of also all is inorganic, because output shaft is provided with an organic gear and two stepless gears, with high speed shaft, reverse gear shaft and lower velocity shaft engagement driving, thereby three organic and six stepless power transfer modes have been formed.Also driving gear can be manufactured helical gear as required.

Stepless speed-changing gear box of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, low cost of manufacture, applied range, easy to operate, energy saving, thereby, have good value for applications.

Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
