Description of the drawings
Fig. 1 is a kind of plug-in mine car dynamical system configuration of heavy type.
Specific implementation mode
The utility model is described in more detail below in conjunction with the accompanying drawings.
The plug-in mine car dynamical system configuration of a kind of heavy type as shown in Figure 1, including driving motor 1, diesel engine 2, Two grades of AMT speed changers 3, gear ring 31, sun gear 33, planet carrier 32, the first transmission shaft 61, second driving shaft 62, power takeoff bar 41, power takeoff driving gear 42, power takeoff driven gear 43, power takeoff output shaft 44, gearbox shifting mechanism 5.Diesel engine Machine 2 is connected by the first transmission shaft 61 with 3 input shaft of speed changer, and 3 output shaft of speed changer is connected with 1 main shaft of driving motor, driving Electric machine main shaft also exports power to the downstream power system including differential mechanism, driving wheel by second driving shaft 62.Power taking Device obtains power from connection driving motor system to the first transmission shaft 61 of speed changer.
Two grades of AMT speed changers 3 include one group of planetary gear, and planetary gear includes gear ring 31, sun gear 33, planet carrier 32, Transmission input shaft is connected with the sun gear in planetary gear, and output shaft is connected with planet carrier 32.Shift mechanism 5 includes speed changer Shell position 52, gear ring position 51, planet carrier position 53, shift mechanism 5 lock gearbox case and gear ring position 51, realize speed changer one Shelves output;Shift mechanism 5 locks gear ring position 51 and planet carrier 32, realizes (direct) output of two grades of speed changer;Shift mechanism 5 is single Solely be placed on a certain position is then neutral gear.
Power takeoff system includes that power takeoff bar 4, power takeoff driving gear 41, power takeoff driven gear 42, power takeoff are defeated Shaft 43.Power takeoff driving gear 41 is set on the first transmission shaft 61, and ratcheting with power takeoff driven gear 42, and power takeoff is driven Gear 42 is connected by the clutch controlled by power takeoff bar 4 with power takeoff output shaft 43.Power takeoff output shaft 43 is for driving Hydrodynamic pressure system realizes that mine car lifts the function that big case is unloaded.
Diesel engine connects two grades of AMT speed changers in this programme, is then connected with driving motor, two grades of AMT speed changers Using uniline star system configuration, wherein sun gear is as input, and planet carrier is as output, while drawing a pair on input shaft can The gear for hanging shelves does and rises big case power takeoff use.
This programme stretches out a gear on shell, stretches out a gear on gear ring, and planet carrier is connected stretching with output shaft One gear.When gearshift puts in first gear, gear ring is formed with shell and is connected, and is equivalent to gear ring and is fixed, plays deceleration torque Effect;When gear is suspended to intermediate neutral gear, there are two degree of freedom for entire planetary mechanism, and it is all not defeated in idle running to be equivalent to whole system Go out power;When gear is suspended to two grades, gear ring is formed with planet carrier and is connected, power 1:1 output, is equivalent to two grades of speed changer.
When gearshift is linked into neutral gear, and power takeoff gearshift is linked into gear, power is exported from power takeoff delivery outlet, real Now stop offloading functions.
When gearshift is linked into other gears, and power takeoff gearshift is linked into gear, power output shaft and power takeoff mouth It exports simultaneously, realizes driving offloading functions.
The heavy mine car of this programme can realize following functions:
1. when starting, directly driven by driving motor, is started to walk using pure electrician's condition.
2. when vehicle is when climbing etc. needs large torque, speed changer puts in first gear, and engine input torque is increased by speed change It turns round, while driving motor power-assisted.
3. when vehicle operates in steady operating mode, speed changer is linked into two grades, is driven by engine direct, when braking, driving motor Carry out energy regenerating.
4. when vehicle stops, when the big case of vehicle needs to unload thing, speed changer is suspended to neutral gear, and power takeoff is linked into gear, by Engine driving, power takeoff push big case to rise, and unload mineral aggregate.
5. when vehicle needs to lift big case operation, power takeoff is linked into neutral gear, and by big case supporting rod pressurize, vehicle is linked into one Shelves are realized that drive-through dumping carries, are driven by driving motor;
6. rise big case when needing driving, speed changer and power takeoff are linked into gear simultaneously, are directly driven by engine, It achieves that and rises big case offloading functions in driving.
This programme uses the scheme that engine adds driving motor after two grades of planet AMT speed changers cooperation gearboxes, can Realize that pure electrician's condition traveling, engine direct drive the cooperation functions such as motor power-assisted and energy regenerating.
This programme additionally uses the two grades of AMT gearboxes of planet row type for being provided with neutral gear, can greatly reduce speed changer cloth Between emptying, and parking offloading functions may be implemented.
This programme designs the power takeoff with gear in transmission input shaft side, can be risen in walking according to actual conditions Big case is played, realizes offloading functions.
