车辆工程专业毕业论文外文翻译---履带车辆转向机构的研究现状及发展趋势(编辑修改稿)内容摘要：

machine type change direction the organization to will be eliminated on the big power tractor, bulldozer...etc. engineering vehicle in the l ast additional liquid in system in machine the liquid of — that pump the motor presses the machine — liquid drives to press to change direction the system will get the application machine liquid press type a power flows to change direction the organization[5,6] from launch the machine and change the deal pump, control valve, fixed amount motor, many files bee soon box and empress bridges change direction to differ to move the organization 5 will spread to flow from the machine that launch the machine power in many files became soon the importation stalk of the box last cent flow, all the way flow through was pressed by liquid pump liquid press motor constitute of change direction adjust soon system。 another all the way flow thr ough many files became soon box, finally experienced star row top confluence, then was lined up by pla of some a the parts( such as pla) spread to the vehicle to spread to move the stalk top the liquid presses to pump to press with the liquid the motor can have no the class controls, therefore using the this type of changing direction the organization since can acquire the car An a lot of weakness for twoth lateral speeds differing realizing having no class controling, again overing machine type changing direction the liquid presses the motor do not work, only ing from central spread the dynamic power flow, the vehicle makes the straight line drives。 if only have the liquid that e from the power press the motor flows, the vehicle can realize to change direction radius as the zero changing direction originally。 if input at the same time two road powers flow, because the liquid presses the motor can realize to have no the class controls, for this reason vehicle two side tracks drive the rotation to have soon and will barely do much more endless, can get the much more endless changes direction the radius, can immediately realize to have no the class changes direction, pilot as long as manipulate to change directio n the dish turns to move the liquid presses the device, can make vehicle driven along the certain arc kind of changes direction the organization not only have the construction good, have no the friction a piece, life span is long, the efficiency is high and work dependable, arrange simple, maintain the adjustment little and lower to can consume to wait the characteristics the outside, but also it is not a motive to pass the part or cut off all a side track in working function to the system move a the side drives a the round realizes to change direction of, but two side tracks deliver the motive always, can realizes nicely like this the motive change direction, basic ascend a safety for slippery phenomenon, being applicable to proceeding being partial to carrying pushing soil with cutting off root homework。 at sloping fields changing direction can39。 t appearing conversing 6 direction phenomenon, increases vehicle that dissolves the track。 because of changing direction do not cut off the motive, the average car of the for this reason vehicle does not lower soon。 the track do not stop driving, breaking to the soil little, in loosenning soft soil of pass the sex good。 change direction the size of the radius can control arbitrarily, increasing the flexi bility of the track vehicle, change direction steady。 change direction vehicle can develop with drive the high work in same function straightly。 realizes easily a the root manipulates the pole to control in to back with change direction. 2 change direction the pure liquid in trend (1)in development in organization press to have no the class changes direction the organization wants to realize the track vehicle changes direction the radius can control and continue to have no the class changes of chan ge direction the function, the adoption capacity type liquid presses to pump to press with the liquid motor etc. has no the class bee soon a piece is a more realistic viable pure liquid presses to change direction the organization[7 9] of ～ ss pas。
