Require according to the car load coupling: driving engine 1 is selected Cummins Engine for use, and version is: six-in-line, four stroke, turbo-charging, high-pressure common rail.Main technical details is: rating horsepower/rotating speed: 275KW/2100rpm; Engine swept volume: 8.9L; Idling: 700 rpm; Maximum no-load speed: 2450 rpm; Bore/stroke: 114 * 145mm; Speed at maximum torque: 1450Nm/1400 rpm; Satisfy state's IV emission request; Unit weight 1157Kg (weight in wet base).
Clutch bell is selected SAE 1# clutch bell for use, can directly dock with transmission gearbox 3 housings, and is fastening through double-screw bolt.Flywheel is selected the import flywheel for use, mainly is the flywheel of domestic nothing and import transmission gearbox coupling.Driving engine 1 directly adopts flexible wet type to be connected with transmission gearbox 3, technology maturation, and function-stable is reliable.
The former factory department of driving engine part is selected in driving engine 1 air inlet, cooling, exhaust etc. for use, calculates through coupling, satisfies the needs that driving engine is operated at full capacity, technology maturation, reliable in function.
Full power power takeoff 2 is loaded on driving engine 1 rear end of the cylinder block face, and power takeoff housing and flywheel shell of engine inblock cast form, and directly link to each other with starting bent axle, spread out of power through gear mesh.Main technical details: speed ratio: 1:1.154, constant-mesh, rotating speed 2300rpm, moment of torsion 2000 Nm, maximum output power reaches 90% of engine power, is positioned at 12 clock directions of clutch bell.Be connected with outer relay part through 4 hole flanges.
The hydraulic transmission gear box that transmission gearbox 3 selects for use the special engineering field to use is used for automotive field first, but its reasonable in design, reliable in function can satisfy the specific (special) requirements of user for the vehicle two way.Main technical details is: power: 450 horsepowers; Maximum input torque: 2900 Nm; Maximum input speed 2700 rpm/ branches; Speed ratio is (4 positive 4 fall): 5.81,2.42,1.38,0.78; Output rotation direction and driving engine rotation direction opposite (seeing) to the flywheel end.
As shown in Figure 2; Said transmission gearbox comprises that turbine transformer 6, pump drive section 7, pressure regulating valve 8, input shaft 9, direction power-transfer clutch 10, gear power-transfer clutch 11, output shaft 12 and speed change control valve 13; Said turbine transformer 6 links to each other with driving engine 1; Said pump drives section 7, input shaft 9 links to each other with turbine transformer 6 respectively, and said pressure regulating valve 8 drives section 7 with pump and links to each other, and said direction power-transfer clutch 10 links to each other with input shaft 9; Said gear power-transfer clutch 11 links to each other with direction power-transfer clutch 10, and said output shaft 12 links to each other with gear power-transfer clutch 11.
Accepting the next power of input shaft 9 transmission is to advance or reverse clutch (being direction power-transfer clutch 10).Direction power-transfer clutch 10 comprises a rotary drum and a cylinder sleeve that holds hydraulic drive piston with internal splines.These cylinder sleeve two ends are provided with seal ring, form an osed top hydraulic chamber, are full of fluid.Chamber interior is equipped with steel disk and the friction disc that has internal splines, is inserted into the friction disc inner ring by a castellated shaft, links to each other with gear power-transfer clutch 11.When not having pressure on the direction power-transfer clutch 10, steel disk and friction disc can move freely in chamber; When direction power-transfer clutch 10 is full of high-pressure and hydraulic oil, steel disk and friction disc will move to selected direction, realize the transmission of power.
In case 10 engagements of direction power-transfer clutch, power just is delivered to (the 1st, the 2nd, the 3rd or the 4th) on the gear power-transfer clutch 11.The principle of work of gear power-transfer clutch 11 and direction power-transfer clutch 10 are similar.
After gear power-transfer clutch 11 engagement, power just finally is delivered to output shaft 12, and it is opposite that the hand of rotation of output and driving engine revolve 1 veer.
Speed change control valve 13 is installed in the mechanism housing outside, is the fluid control valve with electromagnetic valve.Function is that pressure oil is directed on the direction power-transfer clutch 10 and gear power-transfer clutch 11 that needs,
Below one grade be example, set forth the transmission gearbox drive path.One grade of drive path is: engine flywheel through flexibly connect drive pump impeller rotation → pump impeller stir hydraulic oil drive turbine rotation → turbine rotation drive rigidly connected with it input rotation → input shaft with transmission of power give in direction power-transfer clutch (driver's operation is chosen in a P PARK Position P with the gear of speed change control valve simultaneously) → direction power-transfer clutch hydraulic oil with steel disk and friction lining be driven into a P PARK Position P → with 3 grades of power-transfer clutch work → 3 grade power-transfer clutchs of the rigidly connected castellated shaft drive of direction power-transfer clutch with transmission of power to 1 grade of power-transfer clutch work → 1 grade power-transfer clutch with transmission of power to output shaft, one keeps off takeoff output finishes.
The retaining operating path that falls is similar with it, and power is change of direction at direction power-transfer clutch place.When the chaufeur desire will be changed down a retaining, need earlier speed change control valve to be selected in neutral gear position, at this moment, hydraulic oil does not have pressure in the direction power-transfer clutch.Chaufeur changes gear to falling a gear and puts immediately; Direction clutch hydraulic pressure oil is driven into down a gear with steel disk and friction disc and puts → drives 3 grades of power-transfer clutch work → 3 grade power-transfer clutchs with the rigidly connected castellated shaft of direction power-transfer clutch to give output shaft with transmission of power for 1 grade of power-transfer clutch work → 1 grade power-transfer clutch transmission of power, and the retaining takeoff output that falls finishes.
So far, the change of power direction, promptly the two way function realizes.
Overhead power takeoff power is realized the output of power from input shaft through gear mesh.The power taking equipped at outlet port also is equipped with the power takeoff power-transfer clutch, through external hydraulic control, realizes the separation and the combination of power.
The utility model two way power transmission assembly changes process at power direction, can realize the vehicle two way, has broken through special vehicle and has received the restriction of work-yard, and the development of special vehicle is had impetus.This dynamic assembly is through the entrucking test, and its function realizes fully, satisfies customer requirements.Simultaneously, this dynamic assembly provides a full power power taking delivery port, and two overhead transmission gearbox power takeoff takeoff output mouths and a power takeoff clutch control satisfy the user to how power operated requirement, belong to brand-new power matching unit.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
