1、 1 The Track Vehicle Changes Direction Research Present Condition and DevelopmentTrends of The Organization 1 change direction the research present condition of the organization Different classification in basis method, the track vehicle changes direction organization can according to vehicle is in
2、change direction process the power flows of deliver the way is divided into the single power flows to change direction the organization to flow to change direction the organization with a power, and also can according to in change direction process two the sport of side trackses have no the contact
3、but is divided into the independent type change direction the organization with bad soon the type changes direction the organization. 1.1 single powers establish a certain changing direction the organization after flowing change direction the single power in organization flow to change direction the
4、 general structure in organization method is at became soon the organization, is the most simple method to constitute track vehicle change direction to spread to move.The single power flows to change direction the organization to change direction the organization most in brief, among them most in co
5、mmon usely change direction the clutch, single bad soon the machine, double is bad soon the machine, planet changes direction organization etc.Change direction the clutch1,2 is all a friction that several types rub the clutch, depending the friction surface to deliver to turn the , being the separat
6、ion some on changing direction the clutch laterally, can reduce or cut off that side drive a round delivers of turn the make vehicle changed direction.Change direction the size of the radius from drive a decrease for spreads to turn the measures namely the degree that clutch separate decides.Change
7、direction the clutch is simple because of the construction, manufacturing convenience, got the extensive application on the small scaled track in inside in earlier period type tractor, bulldozer.But because its manipulate 2 the sex bad, produce the efficiency low, can consume bigger, enlarge continu
8、ously along with the track vehicle power, change direction the application of the clutch will suffer certainly of restrict.Single Bad soon the machine changes direction the organization2,3 can make vehicle several why the speed of the center position still keeps in change direction process the origi
9、nal driving the car straightly is soon, being a When the complete system in side move, change direction the radius over small, but another side track speed over high, change direction the Cape speed over big, for this reason a power for needing changing direction power very bigly, would outrunning g
10、enerally launching machine restrict, if the pilot keep on changing direction, have a little bit the immodesty and then will make launch the machine fire, as a result can depend to slip to whet, using than the greater half path changes direction, or pole is not fair and softly break to change directi
11、on continuously with the lesser half path.Therefore this kind of is single bad soon the machine change direction the organization to no longer adopt almost now.The speed that a speed for differing soon machine changing direction organization3,4 can making track vehicle at changing direction slowly s
12、oon side track lowering is equal to the fast side track the increment, the for this reason vehicle changes direction of average speed and straightly the speed that drive same alike.But because a variety for badly soon machine cant completely system moving first side track, vehicle cant originally ch
13、anging direction, and changing direction radius scope has no usage to change direction the clutch big, changing direction the going smoothly worse.While changing direction, the fast side track accelerates, therefore launching the affixture of the machine carry the ratio adoption change direction the
14、 clutch big.The double is bad soon the machine be constituted by wheel gear of change direction the organization, with change direction the clutch compare the spare parts number little, bear to whet the sex good, the life span is longer.The planet changes direction the organization4,5 moves with the
15、 system from a planet a department the machine constitutes.The operation planet the system on the organization moves the machine can change two sides drives the round drives the dint size make vehicle changed 3 direction.It is that type of to change direction the organization opposite in change dire
16、ction the clutch change direction the organization can deliver the bigger changing direction the dint , can realize an athletic and fixed stalk wheel gear organization fall through of two free a planet for of flat-out decomposition with synthesizing, planet organization a three dollar as have the ba
17、d relating to soon； change direction the organization to much order to deliver the motive, and the internal path in organization faces the dint mutually equilibrium.But is complicated because of its construction, only industry in big power tractor, bulldozer and other heavy type vehicle last applica
18、tion.Single weakness that power change direction is obvious, vehicle only contain several fix of change direction the radius, press to rule not of change direction When the radius change direction, want to is slipped by friction a piece to whet to realize, and is hard to get the stability change dir
19、ection the radius accurately； the next in order in change direction process rub a dollar piece of violent slip to whet to will bring to have fever with wear away, make spread to move the efficiency lower, especially in the big power change direction work appearance next, would exsit the bigger power
20、 lose, with the result that often need to be declined to change direction soon； moreover, the violent friction also make easy damage in organization, cause the work dependable bad, the life span lower. 1.2 pairs of powerses flow to change direction the organization after launching machine, will laun
21、ch the machine power be divided in to become soon with change direction two roads be juxtaposed to deliver, ising a double of powers to flow to change direction the organization.A power flows to change direction the organization will used for keeping the pushes forward of become soon the organizatio
22、n is different from result in leftly, the right side track speed differs of change direction the organization to be juxtaposed in spread move department, change direction the organization when the vehicle keeps the did not result in twoth the speed of side trackses are bad, while changing direction, became to flow each file of offering soon to drive the speed straightly with change direction the organization results in of two the speed of side trackses differ to remit to flow, realizing the vehicle change direction.
