Description

A kind of mining electric locomotive combination driving system
Technical field
The present invention relates to mining electric locomotive field, especially relate to a kind of mining electric locomotive combination driving system.
Background technology
Tradition diaxon mining electric locomotive type of drive adopts the two individual drive axle mode of double-motor mostly, and namely a motor drives an axle, does not link.Although which is easy and simple to handle, the normal run time behaviour of mechanism is reliable, but it is heavy not etc. at electric locomotive design axle, or when there is axle weight transfer in operational process, double-motor independence mode of traction then cannot balance motor output torque, cause the sticky heavy degree of utilization of electric locomotive to reduce, electric locomotive carrying capacity declines; If a motor breaks down, an axle is then only had to be moving axis, now, the sticky heavy degree of utilization of electric locomotive about reduces half, can not be fully loaded with and work as subtask, need load shedding to run or unload empty wagons to return storehouse repairing, like this, often cause transportation route to block, reduce production efficiency, also can bring potential safety hazard if process not in time, bring inconvenience to production.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the above-mentioned defect that prior art exists, and provides a kind of reliable operation, mining electric locomotive with low cost to combine driving system.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of mining electric locomotive combination driving system, comprise front haulage motor, rear haulage motor, front reduction gear, rear retarder, front coupler, rear coupler, power-transfer clutch, intermediate shaft coupling, front wheel spindle, hind axle, be connected by front coupler between front haulage motor output shaft with front reduction gear input shaft, rear reducer input shaft is connected by rear coupler with rear haulage motor output shaft, power-transfer clutch and intermediate shaft coupling is connected with between front reduction gear and rear retarder, the output shaft of front reduction gear is front wheel spindle, front wheel spindle and front vehicle wheel are connected, the output shaft of rear retarder is hind axle, hind axle and rear wheel are connected.
Further, described power-transfer clutch is friction clutch, and friction clutch two end axles is connected with friction lining.
The principle of work of the mining electric locomotive combination driving system of the present invention is: front haulage motor, rear haulage motor is all energized startup, front haulage motor output shaft and rear haulage motor output shaft rotate, front haulage motor drives the input shaft of front reduction gear to rotate by front coupler, after rear haulage motor is driven by rear coupler, the input shaft of retarder rotates, thus drive transmission shaft at different levels in front reduction gear to rotate by the gear pairs at different levels in front reduction gear, after being driven by the gear pairs at different levels in rear retarder, in retarder, transmission shaft at different levels rotates, front reduction gear output shaft and rear reducer output shaft drive locomotive two wheel to roll in orbit respectively, realize locomotive straight line moving, front reduction gear, rear retarder rotarily drives power-transfer clutch two end axles by the adapter shaft of power-transfer clutch and rotates, friction lining phase mutual friction in power-transfer clutch two end axles, the reasonable distribution of friction moment is realized by the friction between two friction linings.
When locomotive operation is on straight track, if the axle heavy phase etc. of front wheel spindle and hind axle, then without axle weight transfer, the output torque of front haulage motor and rear haulage motor is equal, zerofriction force between two friction linings now in power-transfer clutch two end axles, power-transfer clutch two end axles with friction lining separately with front reduction gear, rear retarder rotates together, under this working condition, power-transfer clutch can close or be separated (when power-transfer clutch closes, because front and back traction electric machine output torque is equal, now, the moment that power-transfer clutch two end axles is transmitted is equal, unable state is between two friction linings in power-transfer clutch two end axles, namely friction moment is not produced each other, on transmission without impact, during disengaging of clutch, two friction linings in power-transfer clutch two end axles do not contact, and do not produce friction moment each other, on transmission also without impact), front wheel spindle, hind axle self contained function.
If the axle of front wheel spindle and hind axle heavy unequal (as axle resets axle that meter do not wait or occur axle weight transfer to cause heavily not etc.), the heavy lighter wheel corresponding to wheel shaft of axle will have the trend of tyre skidding, at this moment, friction force is produced between two friction linings in power-transfer clutch two end axles, the traction electric machine output torque be connected with the heavy lighter wheel shaft of axle is realized to distribute a part on the heavy heavier wheel shaft of axle, can make full use of electric locomotive sticky heavy, improve electric locomotive carrying capacity, moment transfer computing formula is ( > time) or ( > time), in formula, -front wheel spindle axle weight, -hind axle axle weight, i-front and back retarder transmitting ratio, -adhesion factor, r-radius of wheel; In two traction electric machines in front and back, if wherein a traction electric machine breaks down, power-transfer clutch also can steadily reliably drive front wheel spindle and hind axle to rotate, and the output torque of a wherein traction electric machine is heavily carried out reasonable distribution according to axle, make full use of electric locomotive sticky heavy, realize the traction of single motor and be fully loaded with and work as subtask.
Compact conformation of the present invention, reliable operation, both can realize dual-motor combination running under power, gave full play to the towability of electric locomotive, improved electric locomotive carrying capacity; Can realize again single motor in short-term independently to draw, when a motor breaks down, single motor traction has been fully loaded with and has been worked as subtask, keeps transportation route unimpeded, is conducive to enhancing productivity, reduce potential safety hazard.
