Description
Affiliated technical field
The present invention relates to a kind of automotive transmission, relate to a kind of comprehensive fluid torque converter and one group of differential planet gear specifically, realize the hydraulic planetary automatic stepless speed variator of automative stepless speed-variation transmission.
Background technique
Stepless speed variator is the highest goal of vehicle transmission, and the stepless speed variator that is applied in now on the automobile has only " metal band type stepless speed variator ", its complex structure, and transfer motion power is limited, and application area is also wideless at present.Other all is that a grade automatic transmission is arranged.Realize also not the having of present application of stepless change transmission by gear.
Summary of the invention
The invention provides a kind of hydraulic planetary automatic stepless speed variator, this speed changer is the direct transmission of differential planetary speed changer, comprehensive fluid torque converter control speed governing, driving torque is big, the transmission efficiency height, gear range is big, the stepless variation of velocity ratio has really realized stepless change, and simple in structure, stepless change is adjusted automatically, and speed change is fast.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of hydraulic planetary automatic stepless speed variator, comprise selector, converter clutch and comprehensive fluid torque converter, its structure outline is: input shaft connects said converter clutch by selector, this converter clutch connects said comprehensive fluid torque converter, the output shaft of this comprehensive fluid torque converter connects the driving gear of the differential planetary gear train of being made up of gear, input shaft connects said sun gear by said selector, the output shaft of said comprehensive fluid torque converter connects driving gear, this driving gear engagement driven gear, the coaxial connection synchromesh gear of this driven gear, this synchromesh gear engagement external toothing, said external toothing and sun gear drive planet wheel, said planet wheel drives planet carrier, and this planet carrier connects output shaft.
The coaxial connection overdrive gear of said driven gear, this overdrive gear connects said external toothing.
The overgear clutch is installed between said synchromesh gear and the overdrive gear, and this overgear clutch can connect synchromesh gear or overdrive gear.
Said differential planetary gear train outside is provided with shell, is provided with overrunning clutch in this shell, and the outer ring of this overrunning clutch is fixed on the shell, and the inner ring and the driving gear of this overrunning clutch are fixedly connected.
Between said shell and external toothing, break is installed.
Said input shaft directly connects with sun gear by selector, input shaft connects said converter clutch by selector simultaneously, this converter clutch connects said comprehensive fluid torque converter, the output shaft of this comprehensive fluid torque converter connects driving gear, this driving gear engagement driven gear, this driven gear connects with synchromesh gear or overdrive gear by gear shaft and overgear clutch, synchromesh gear or overdrive gear connect external toothing, it between this external toothing and the sun gear planet wheel, planet carrier connects output shaft, said differential planetary gear train outside is provided with shell, be provided with overrunning clutch in this shell, the outer ring of this overrunning clutch is fixed on the shell, and the inner ring and the driving gear of this overrunning clutch are fixedly connected, and break locking external toothing is installed between said shell and external toothing.
Working procedure of the present invention is: under the normal condition, by control system converter clutch is often connected, the overgear clutch often connects with synchromesh gear, break does not lock external toothing, here the gear train assembly with comprehensive fluid torque converter back is called differential planetary gear train, input shaft has the input of slow-speed of revolution moment of torsion when starting, the converter clutch that input shaft drives is because rotating speed is low, the torque converter output shaft output torque is little, can not drive external toothing rotates, this moment, input shaft directly drove the output shaft rotation with maximum transmission ratio, this moment the starting torque maximum, along with input shaft reaches certain rotating speed, input shaft drives torque-converters, torque converter output shaft drives external toothing and rotates, reduce the velocity ratio of differential planetary change gear train, quickening along with input shaft speed, the external toothing that torque-converters drives differential planetary gear train speeds up, the velocity ratio of differential gear train is dwindled gradually, the speed of output shaft is also more and more faster, because the characteristic of comprehensive fluid torque converter makes that the velocity ratio of differential planetary gear train can be from maximum stepless change to 1: 1, really realize large-scale stepless change.The effect that is fixed on the overrunning clutch on the shell is to prevent the external toothing counter-rotating.Range of transmission ratio can be formulated by the design of differential planetary gear train, and optional scope is big.When the needs overdrive, make the overgear clutch disconnect synchromesh gear by control system and connect overdrive gear, make the external toothing rotating speed be a bit larger tham the rotating speed of torque-converters output, can realize overdrive.When climbing the output of high pulling torque such as steep gradient when needs, converter clutch is separated, engine power is directly exported by planetary reducer.Separating torque-converters is in order to protect torque-converters not burnt by high temperature.Selector is variable to be changed to forward gear, neutral, reverse gear.To lock external toothing by break when reversing gear.Because between output shaft and the input shaft is that rigidity is connected all the time, so can the macro-energy transmission.Control of the present invention can be adopted the full hydraulic control system, also can adopt the electrolyte type control system.Can also design the more advanced control system of application controls.The said selector of the present invention, comprehensive fluid torque converter, break adopt the general selector in related domain, comprehensive fluid torque converter and break, and said converter clutch, overgear clutch adopt general clutch as the case may be.
The invention has the beneficial effects as follows that it is simple and direct that the present invention has principle, simple in structure, control easily, slewing range is big, real stepless change, the power of transmission is big, the transmission efficiency height, applied range, part is few, easily makes, and cost is low, uses easy to maintenance.If be applied on the automobile, no matter Light-duty Vehicle, heavy goods vehicles can both guaranteed performance.Further improve design if use this design proposal, then have more extensive industry to promote.
