Abstract
The present invention provides a kind of two-axis locomotive transmission systems, including a frequency-variable module, two traction electric machines, two universal shafts and two axle gear boxs, the frequency-variable module input terminal is connect with power accumulator or contact net, the output end of frequency-variable module is separately connected two traction electric machines, and the output end of two traction electric machines is backwards to the axle gear box for being arranged and transmitting power to respectively by universal shaft axle both ends.The beneficial effects of the present invention are: being driven respectively using two traction electric machines to two axle gear boxs, even if one of traction electric machine breaks down, another traction electric machine still can normally draw work, embody the theory of Redundancy Design；The novel transmission system can both have been guaranteed the utilization demand under different working conditions, and be also beneficial to realize environmentally protective using a variety of different dynamic sources such as power accumulator, power grids.
Description
Technical field
The present invention relates to a kind of two-axis locomotive transmission systems, belong to technical field of rail traffic.
Background technique
Mainly based on hydraulic power, internal combustion engine and hydraulic transmission gear box are mounted on vehicle frame current two-axis rail locomotive,
Internal combustion engine provides power and drives hydraulic transmission gear box output torque, passes through universal shaft and axle gear box driving wheel pair.Such as Fig. 1 institute
Show.
The power source of hydraulic drive system is often internal combustion engine, and the power of internal combustion engine is passed to axle tooth by hydraulic transmission gear box
Roller box and driving wheel pair.Due to not high using hydraulic transmission gear box transmission efficiency, combustion engine powered source is difficult to adapt to existing green
Environmental requirement.
Summary of the invention
Goal of the invention of the invention is: in view of the above problems, providing a kind of two-axis locomotive transmission system.
The present invention provides a kind of two-axis locomotive transmission systems, including a frequency-variable module, two traction electric machines, two
Universal shaft and two axle gear boxs, the frequency-variable module input terminal are connect with power accumulator or contact net, frequency-variable module
Output end is separately connected two traction electric machines, and the output end of two traction electric machines is arranged backwards and passes through universal shaft respectively for power
It is transferred to the axle gear box at axle both ends.
The present invention also provides a kind of two-axis locomotive transmission systems, including two frequency-variable modules, two traction electric machines, two
Root universal shaft and two axle gear boxs, two frequency-variable module input terminals are connect with power accumulator or contact net, often
The output end of a frequency-variable module connects a traction electric machine, and the output end of two traction electric machines is backwards to setting and respectively by universal
Axis transmits power to the axle gear box at axle both ends.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, two axle gear boxs are driven respectively using two traction electric machines, even if one of traction electric machine goes out
Existing failure, another traction electric machine still can normally draw work, embody the theory of Redundancy Design；
2, the novel transmission system can both have been guaranteed not using a variety of different dynamic sources such as power accumulator, power grids
With the utilization demand under working condition, it is also beneficial to realize environmentally protective.
