Technical field
The utility model relates to transport facility field more particularly to the power battery power transmission cables of tractor.
Technical background
With more serious municipal pollution and energy shortages phenomenon, new-energy automobile, especially pure electric automobile enter
The fast traffic lane of development.Various regions government launches respectively relevant policies, is helped encouragement, it is expected that pure electric vehicle industry is allowed more to be grounded whereby
Gas is received by users.
It is compared with general car, the time that tractor travels daily is longer, and the energy and cost of consumption are more, therefore pure electricity
The development of dynamic tractor is more meaningful for implementing for national energy conservation and emission reduction target.But it is various by charging time, course continuation mileage
Limitation, is mainly used in point-to-point short-distance transport at present, can't really replace diesel tractor, reach wanting for long-distance transport
It asks.
In order to make tractor that there is enough course continuation mileages, and guarantee the explosive force of vehicle, it is contemplated that tractor drags
Vehicle space is sufficiently large, is capable of providing bigger installation space for configuring the tractor power battery of bigger power reservoir capacity, therefore
Power battery can be placed in trailer, but this configuration mode, it can power battery and the preposition height in headstock is voltage-controlled
Cabinet processed separates, and needs to be transmitted electricity with special high voltage cable.
In turning, trailer can turn left and right tractor relative to headstock, and the two is made no longer to keep substantially coaxial, but
Have angle, thus the distance between power battery and high voltage control cabinet can be made to become larger, be accordingly used in connection power battery and
The high voltage cable of high voltage control cabinet needs enough length surpluses to adapt to this variation, and high voltage cable can quilt when negative is turned
It pulls apart.
High voltage cable is not appropriate for being processed into spring coil to adapt to above-mentioned distance change, this is because high voltage cable is defeated
For power transmission pressure usually in 600V or more, line footpath is thicker, and the structure of spring coil can make heavy current form ring, causes electromagnetic interference,
Influence vehicle operation；But the high voltage cable of straight line again can be too long and loose sagging when vehicle body is ajusted, the vehicle body in traveling can
Cable can be worn, cause to leak electricity, generate bigger harm.
