Description
Technical field
The present invention relates to a kind of mekydro composite transmission, more particularly to it is a kind of for the engineering with implement
The mekydro composite transmission of vehicle.
Background technology
Currently, many engineering trucks need at least two mode of operations：First, vehicle can run at high speed, and realization is quick to be turned
；Second, vehicle can be while run at a low speed, while driving implement to carry out operation.To meet the purpose, these engineering trucks
Generally realize the demand using two electromotors.That is, on the truck chassis of a routine, it is provided with first and starts
Machine, referred to herein as traveling electromotor, there be the parts such as change speed gear box, drive axle, vehicle frame, tire on chassis, driver can with open
The common the same mode of truck drives the high vehicle speeds or runs at a low speed；In addition, being also equipped with second on chassis
Electromotor, referred to herein as operation electromotor, by second driven by engine implement operation, usual implement work(is carried out
Rate is all than larger.That is this engineering truck be two sets of completely self-contained dynamical systems are simply superimposed it is integrated,
A set of dynamical system is responsible for vehicle traveling, and another set of dynamical system is responsible for operation.
Prior art has the disadvantage that：
1. engine consumption is big, discharge is big, noise is big, loss is big；
The operation travel speed of some vehicles is very low, such as speed per hour is 5 to 8km/h；Realize the operating speed, it is necessary to
Chassis traveling electromotor is placed in idling speed (800-1000rpm), and the change speed gear box of vehicle will also be placed in low gear
Upper (the usually starting gear of large speed ratio), could realize the low speed operating speed.However, engine in situ long-term work is idle
On the non-economy rotating speed of fast 800-1000rpm (economic speed is usually 1500-2400rpm, depending on concrete vehicle), not only
Oil consumption is big, and it is poor to discharge, and the loss of electromotor itself is also big；In addition, in order to drive powerful implement to work, operation is started
Machine generally needs to be arranged on high-power and high-speed state（Usually 2000-3000rpm, depending on specific model）, two are started
Machine works simultaneously, and not only oil consumption is high, noise is big, waste gas discharge is also big, and the theory of environmental protection and energy saving is not met completely.
2. vehicle operation efficiency is seriously reduced, and energy consumption wastes serious；
For engineering truck, ideally, the space on vehicle chassis top should all leave implement for and use.But
It is that, because operation electromotor needs to be arranged on truck chassis top, operation electromotor occupies in itself very big volume and weight,
Also need to the auxiliary device such as supporting fuel tank, air inlet, aerofluxuss, vent gas treatment, radiating, noise reduction for installing correlation for it, these equipment
Presence heavy compression should leave the space of implement for, one way activity duration for directly resulting in vehicle greatly shortens, car
Continuous working period is not long, and energy consumption wastes serious.
3. vehicle maintenance upkeep cost is high：
One this engineering truck has two electromotors, related machine oil, machine filter, air filter, fuel filter, anti-icing fluid, row
Put the consumptive materials such as additive to be required for regularly replacing or add, maintenance cost is multiplied than an electromotor.
Therefore, a kind of drive system how is provided, for significantly improving the work of these engineering vehicle engines and car load
Efficiency, this is those skilled in the art's technical problem urgently to be resolved hurrily.
