Second mouth and 5 coaxial connections of coupling spindle, perhaps coupling spindle 5 directly is set to second mouth of bevel differential, because the bogie truck that this programme is used, be unified design with the disclosed manifold type actuating device of this programme, in the position of coupling spindle 5, traction electric machine 1 and bevel differential, height etc. all has perfect design, so can make the mouth and the coupling spindle 5 coaxial settings of bevel differential, and guarantee the concordant of coupling spindle 5 with the bogie truck bottom, do not influence the effect of low floor.
The wheel shaft of driven independent wheel 7 is provided with the 3rd gear, be provided with the 4th gear at coupling spindle 5 and driven tooth roller box 4 bonded assemblys one end, the 3rd gear is connected with the 4th gear mesh, makes coupling spindle 5 and driven independent wheel 7 interlocks, and the 3rd gear and the 4th gear are arranged in the driven tooth roller box 4.
For guaranteeing that initiatively independent wheel 6 is identical rotating speed with driven independent wheel 7, first gear on the wheel shaft of initiatively independent wheel 6 and driven independent wheel 7 is identical with the 3rd radius; Coupling spindle 5 is positioned at the 4th gear of driven tooth roller box 4 one ends, and is identical with second tooth radius on first mouth of bevel differential.Make so independently take turns in the active at axle Biodge device 8 two ends 6 identical with driven independent wheel 7 rotating speeds.
The propulsive effort that traction electric machine 1 provides is delivered on the bevel differential input end in the drive gear carrier 3 by plunging joint 2, first mouth of bevel differential, by first gear on the independent wheel of active 6 wheel shafts and the second gear mesh transmission on the mouth, propulsive effort is passed to active independently take turns 6.Another mouth is delivered to propulsive effort in the driven tooth roller box 4 by coupling spindle 5, and by the 3rd gear and the 4th gear meshing propulsive effort is passed to driven independent wheel 7, makes initiatively independent wheel 6 and driven independent wheel 7 co-rotation.
When vehicle operating, friction between wheel and the track can drive by institute's bonded assembly and produce moment of torsion stress, when vehicle during by the less little curve of radius, friction force between the wheel track is big, the moment of torsion stress that is produced is big, be provided with disc spring and power-transfer clutch in bevel differential, disc spring and clutch engagement are used, and power-transfer clutch is a multidisk clutch.Be connected by clutch transmits between the finishing bevel gear cuter of each mouth of bevel differential and the input end finishing bevel gear cuter, and be outside equipped with disc spring at power-transfer clutch, disc spring and power-transfer clutch are installed between the input end finishing bevel gear cuter of two mouth finishing bevel gear cuters and diff.On the moment of torsion stress stress set greater than disc spring in limited time, disc spring can make power-transfer clutch that the finishing bevel gear cuter of input end gear with the curve inner side mouth separated, make both sides independently take turns 13 and produce different speed, the rotating speed of the independent wheel 13 in the outside is faster than the inboard, when vehicle passed through bend smoothly, friction force reduced, the power-transfer clutch return, make the finishing bevel gear cuter of mouth obtain power again, return to both sides and independently take turns 13 same rotating speeds.
The low-floor light rail vehicle of using this actuating device is when different rail running, and it is as follows specifically to drive situation:
When vehicle moves on straight track, traction electric machine 1 output torque passes to drive gear carrier 3 by plunging joint 2, this moment, box of tricks 19 was failure to actuate, the power of two mouths still is provided, box of tricks 19 in the drive gear carrier 3 passes to driven tooth roller box 4 by coupling spindle 5 with identical rotating speed, and pass to driven independent wheel 7 in the driven tooth roller box 4, and making that independent wheel 13 rotating speeds of same axle Biodge device 8 both sides are identical, type of drive is identical with the conventional rigid car wheel structure.
Vehicle is during by the bigger big curve of radius, friction force that produces and moment of torsion stress make box of tricks 19 actions inadequately, make drive gear carrier 3 pass to the both sides wheel with identical rotating speed by coupling spindle 5 with driven tooth roller box 4, because both sides wheel and track contact surface, be that tread is a tapered configuration, the outboard wheels rotating diameter is bigger, interior outboard wheels cireular frequency difference, can pass through curve smoothly, identical with the conventional rigid wheel to the curve negotiating form.
At vehicle during by the little little curve of radial angle, the vehicle rotating diameter that the vehicle tread conicity is produced changes, can not effectively pass through curve, when wheel-rail friction power increases, the moment of torsion stress that produces increases in limited time last that box of tricks 19 sets, box of tricks 19 makes and inboard independent wheel 13 bonded assembly bevel differential mouths, separate with the input end of bevel differential, make inboard independent wheel 13 run out of steam, independent wheel 13 rotations in the outside, produce different speed, smoothly by little curve.When by behind the little curve, along with the minimizing of friction force, independently take turns 13 bonded assembly bevel differential mouths with the inboard and be connected with input unit again, guarantee that both sides vehicle rotating speed is identical.
As mentioned above, given in conjunction with the accompanying drawings scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
