Description
Technical field
Dynamic power shift gear box is the utility model is related to, fixed axle gearbox is kept off more specifically to one kind two.
Background technology
Existing common locomotive traction is gearbox with transmission device, is broadly divided into two classes：Fluid power is shifted gears and mechanical changeover.
Fluid power is shifted gears, and mainly uses multi-cycle circular knitting machine structure, is shifted gears by being realized in good time " oil-filled " of different elements and " oil extraction "；Machinery
Gearshift, after main clutch separation, power flow, which disconnects, to be transmitted, and in this case, each gear clutch selects according to ratio demand
Selecting property engages, and so as to realize gearshift function, shifting element has the mechanisms such as synchronizer, cat's paw's jaw clutch.
Using fluid power shift transmission mechanism, there is following problem；(1) transmission efficiency of hydrodynamic unit is low, in order to obtain phase
Ad eundem transmits moment of torsion, and engine power and driving torque demand are into positive correlation, and the power of engine needs to increase under some operating modes
More than 50% is added to can be only achieved equal transmission moment of torsion；(2) because fluid power is shifted gears using " oil-filled " and " oil extraction " to realize gear
Position switches, and the fluid in fluid torque-converter circulation circle is oil-filled and oil extraction is required for the time, generally requires the time of more than 10 seconds, leads
Gearshift is caused to be grown with commutating period, priming speed is slow.(3) due to the engine of Same Efficieney, using multi-cycle circle hydraulic power dress

With high costs, economy is poor.Hydraulic transmission system is justified using multi-cycle on high powered diesel locomotive at present, its maximum
Superiority is reliability height.
Small-power diesel locomotive is generally used for mechanical gear, the less application in high-power locomotive.Machine driving
There are the following problems for case：(1) need car to stop commutation when shifting gears or commutate, power flow be present and cut off situation；(2) machine driving
Form is hard axis connection, and when running into abnormal conditions or high pulling torque loads, engine easily stops working；(3) hard axis connection transmission punching
Hit larger, be directly delivered to engine, cause the unconventional damage of internal combustion engine, reliability is poor.Mechanical gear has damage simultaneously
Potential risk, therefore the reliability of mechanical gear is poor, in the case where loco-hauled bogie is higher to reliability requirement, machine
Tool passes case using fewer and fewer.
