Description
Technical Field
The invention relates to the technical field of power-concentrated motor train units, in particular to a power-concentrated motor train unit and a separable linkage joint-control power carriage.
Background
At present, the power-concentrated motor train unit has mass production and successful application cases in China and the world, and has the advantages of low cost, flexible grouping, variable maximum power, accordance with existing line conditions and overhaul resources and the like under the condition of meeting the speed grade requirement of a carrying task.
Taking a power concentrated electric vehicle with 160 km/h as an example, the group grouping type is as follows:
short grouping: 1Mc +7T +1 Tc;
long grouping: 1Mc +16T +1 Mc;
flexible grouping: 1Mc + 9-16T +1 Mc.
Wherein: mc is the power car with cab, T is the trailer, Tc is the trailer with cab, i.e. the control car.
The axle weight of the power vehicle is not more than 21t, and the axle weight of the trailer and the control vehicle is not more than 16.5 t.
The motor train unit needs to have interconnection requirements, namely, the motor vehicles and the motor vehicles of different manufacturers, and the control vehicle and the motor vehicles need to be matched and applied. In order to realize interconnection and intercommunication of the motor train unit, the motor train unit network control system needs to be unified in the aspects of network initial operation, train level data transmission protocols, main control functions, human-computer interface display screens, fault code rules and the like, and needs to meet unified technical specifications.
According to the transportation requirements, as shown in fig. 1 and fig. 2, two rows of short-marshalling motor train units can be operated in a manner of reconnection at the end of a control train and the end of a control train and a power train, and the reconnection end coupler buffer device adopts a tight-lock coupler buffer device with an electric coupler. The end cars at two ends of the motor train unit are provided with the drivers 'cabs, the motor train unit is controlled by the front driver cab during normal operation, and other drivers' cabs are all automatically locked and cannot simultaneously occupy. And the power vehicle and the trailer are subjected to information interaction and control through a network and a hard-wire interface. The information of the trailer is transmitted to a driver cab of the power vehicle/control vehicle for display through a LonWorks/MVB gateway. The head and tail power vehicles or the control vehicles communicate with each other through a WTB bus. Train-level control hard lines which are required to be arranged on the motor train unit comprise a safety loop, a vehicle door control, an electro-pneumatic brake, an external illumination, an emergency traction and the like.
However, since the power units of the conventional power-concentrated motor train unit are concentrated on the power cars, the axle weight of a single power car is limited, the adhesion effect of the power axle is directly influenced, and when the traction or braking force is large, the situation of runaway sliding is easily caused, so that the acceleration and deceleration performance of the power-concentrated motor train unit is lower than that of the power-dispersed motor train unit, and the operation speed and the like are severely limited. At present, domestic power-concentrated motor train units mostly run on road sections with the speed of less than 200 kilometers per hour, and therefore power-dispersed motor train units are mainly used for high-speed railways.
In conclusion, the power-concentrated motor train unit has weaker acceleration and deceleration control capability, the axle weight is reduced, and the improvement of the operation speed becomes the development bottleneck of the power-concentrated motor train unit.
Based on this, the prior art still remains to be improved.
