Description
Technical field
The present invention relates to a kind of double dynamical input type three and keep off endless-track vehicle variator.
Background technology
China is Rice Production maximum in the world and country of consumption, Annual planting area about 28,600,000 hectares, accounts for whole world rice seed
Plant the 1/5 of area, produce 1.85 hundred million tons of rice per year, account for the 1/3 of Gross World Product, paddy fields in south china region mainly comprise Hunan,
Ten provinces such as Jiangxi, Guangdong, Guangxi, rice yield accounts for the whole nation more than 60%, is the main producing region of China Oryza sativa L..The Rice in Southern China owner of farmland
Want rice cultivation and cole crop, paddy fields in south china almost long-term hydrops, moisten without frost, soil winter, bearing capacity of soil
Difference, after wheel-type working machine tool enters rice field, sinkage is big, and the minimum earth point of wheel exceedes plough sole, and the gear teeth destroy plough sole
Structure, causes plough sole soft.After the operation repeatedly of wheel-type working machine tool, the plough sole degree of depth is constantly deepened, every farming once,
Cultivating plough sediment layer is just made to deepen once, after plough sole is deepened, it is necessary to larger diameter wheel and more high-power and the work of weight
Industry machinery, in turn result in vicious cycle, make paddy field become deep mud feet fields, time the most to a certain extent, can cause plough facility,
The machinery such as rice transplanter, united reaper cannot be gone to the field operation.And submerged weir flow can improve crop yield, reduce heavy metal
Pollute, reduce fertilizer amount and the water and soil that protects the fields.But, near the rice harvesting phase, continuously submerging can make rice field more
Soft, skidding and sunken car easily occurs in Conventional drum agricultural machinery, it is impossible to complete elemental operation.
Caterpillar for agricultural operation mainly has caterpillar tractor, crawler-type harvester and crawler type farmland transfer car(buggy)
Deng.The variable ratio drive system of these endless-track vehicles generally uses two types, and one is to use Purely mechanical power drive system
Transmission power, it has simple in construction, an efficiency advantages of higher, but Purely mechanical power drive mechanism, gear shift operation is complicated,
Drive a car or the technical ability of tractor simultaneously because agricultural machinery operator does not the most possess, to clutch, throttle, the cooperation of gearshift
It is difficult to control, and then limits the development of tractor.Another kind be use hydraulic pump-motor integrated device endless-track vehicle without
Pole variable speed drive system, the endless-track vehicle driving convenience of electrodeless variable-speed drive system is improved, and agricultural machinery operator need not
Participate in the technical training of specialty, it is only necessary to simple exercise can grasp driving efficiency, thus is liked by users, but add
After hydraulic system, drive system efficiency reduces, and thermic load increases.The particularly crawler type during daily production and application is dragged
Machine drawing agricultural machinery and implement to be mounted, and agricultural machinery and implement are when farm work, electromotor is typically in large throttle state, close to sending out
Motivation declared working condition, travel speed change is little, and the output of power and moment of torsion is bigger, cause system energy consumption height, caloric value greatly,
Poor high temperature stability, seriously limits the range of application of caterpillar.
Simultaneously because the operation principle of endless-track vehicle driving system is similar with the travel operation principle of two-wheeled agricultural machinery, speed change
Device be generally integrated turn to, differential, main deceleration, one or more functions such as braking, and at least want integrated turning function.?
Integrated steering device aspect: caterpillar in the market generally uses steering linkage operation jaw clutch and polydisc
Formula brake turn to scheme, it realizes process and is: when caterpillar tractor vehicle turns to the left, and operator turns left
Left side jaw clutch is made to separate and the braking of left side output shaft, due in crawler tractor vehicle left side transfer motion power to pull bar
Breaking and brake and stop the rotation, now under the driving of tractor right side power, facility realize turning to the left；In like manner can realize
Right hand steering, but this steering mechanism uses and separates and combine jaw clutch and brake realization, it turns to precision low,
Steering manipulation is poor.In terms of integrated braking, the endless-track vehicle of part farmland operation such as caterpillar tractor, crawler type gather in
Machine is slow due to travel speed, and after cutting off power, machinery stops fast, does not the most install brake.But in order to improve endless-track vehicle
Travel safety, some endless-track vehicles are mounted with brake unit, and these brake units are typically mounted near driving wheel, due to
Being arranged on drive system end, brake unit is frequently with dry type friction disk type brake, and brake structure is big, left and right wheels symmetry cloth
Putting, quantity is many, and braking concordance is poor.
Simultaneously because the stepless speed change device of hydraulic pump-motor integrated, although nothing can be realized by changing hydraulic pump swash plate angle
Level transmission, but in the stepless change procedure of rotating speed, when this device works near amount rotating speed, efficiency is high, moment of torsion output is steady
Fixed, but when tick-over, hydraulicdriven efficiency reduces, and the output moment of torsion of hydraulic motor is little, limits endless-track vehicle high
Effect job area.
