Description
Technical field
The present invention relates to a kind of tooth rail car driving device.
Background technology
Tooth rail car has the unique advantage that conventional vehicles is incomparable in snow removing, mountain region rescue etc., has the advantages such as climbing capacity is strong, abrupt slope driving power is powerful, is particularly well-suited to mountain region and speedily carries out rescue work.
At present, domestic tooth rail car is applied to mining machinery mostly, adopts electric power-Hydraulic Double power source to drive: to be driven tooth rail car both sides wheel by motor, and by Driven by Hydraulic Cylinder and rack rails meshed gears, car load overlaps power source by two and realizes wheel rail drive and rack drives.
Summary of the invention
The technical problem to be solved is, drives the deficiency needing two set power sources for existing tooth rail car, it is provided that a kind of tooth rail car driving device being achieved that rack drives and wheel rail drive by a set of drive system.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of tooth rail car driving device, including a motor, gear drive, one axle drive gear is arranged on the axletree of wheel through bearing shell, fixedly mounting clutch on the axletree of axle drive gear side, this clutch unclamps with axle drive gear/compresses and is connected; One hollow axle is fixed on axletree by bearing, and fixedly mounts idler gear and rack rails meshing gear on this hollow axle; This gear drive engages with axle drive gear and idler gear simultaneously; When clutch unclamps, motor power passes to hollow axle by gear drive and engaging of idler gear, is having rack rails section, and hollow axle transmits power through rack rails meshing gear and realizes rack drives, and axletree maintains former kinestate; When clutch compresses, clutch, axle drive gear, bearing shell and axletree are fixed as one, and motor power is passed to axletree by gear drive realize wheel rail drive with engaging of axle drive gear.
Further, described gear drive includes fixing the first gear connecting this motor output shaft, the second gear engaged with the first gear, the 3rd gear engaged with the second gear, fourth gear coaxially connected with the 3rd gear, the 5th gear.
Further, described axletree installs described axle drive gear through ring parts, bearing shell.
Further, described clutch and ring parts interference fit joint are on described axletree.
Further, described idler gear and rack rails meshing gear interference fit joint are on described hollow axle.
The present invention is provided power by a motor, unclamping or compressing bearing shell decision power conduction pattern by clutch, it is achieved wheel and the self-movement with rack rails meshing gear, it is to avoid linear velocity is different because wheel moves from rack rails meshing gear simultaneously interferes.
Compared with prior art, the present invention is had the beneficial effect that
A) present invention achieves that tooth rail car conversion between wheel rail drive and rack drives by a set of drive system (motor), namely the mode mixed by power is achieved that the conversion between wheel rail drive and rack drives.
B) because the mixing of present system power, rack drives and wheel rail drive can pass through system switching and realize, so decreasing the bogie kind needed for a joint car, further, since bogie kind reduces, manual maintenance cost is reduced.
C) present invention determines power conducting path by the unclamping compression bearing shell of clutch, makes the switching of drive system power delivery mode relatively reliable.
Accompanying drawing explanation
Fig. 1 is the systematic schematic diagram of tooth rail car driving device of the present invention.
Detailed description of the invention
As it is shown in figure 1, tooth rail car driving device of the present invention includes a motor 1, gear drive 2. Gear drive 2 includes the first gear 21 of the fixing output shaft connecting this motor 1, the second gear 22 engaged with the first gear 21, the 3rd gear 23 engaged with the second gear 22, fourth gear 24, fiveth gear 25 coaxially connected with the 3rd gear 23. One axle drive gear 3 is arranged on the axletree 9 of wheel 11 through bearing shell 4, and the axletree 9 of the side of axle drive gear 3 fixedly mounts clutch 10, and this clutch 10 unclamps with axle drive gear 3/compresses and is connected. One hollow axle 8 is fixed on axletree 9 by bearing, and fixedly mounts idler gear 6 and rack rails meshing gear 7 on this hollow axle 8. 4th gear the 24, the 5th gear 25 of this gear drive 2 engages with axle drive gear (3) and idler gear (6) respectively.
The specific works process of the present invention is:
(1) when clutch 10 unclamps, the power of motor 1 passes through first, two gears 21, 22 pass to the 3rd gear 23, the axle at the 3rd gear 23 place drives the 4th gear 24 and the 5th gear 25, with engaging of idler gear 6, motor power is passed to hollow axle 8 then through the 5th gear 25, there iing rack rails section, hollow axle 8 transmits power through rack rails meshing gear 7 and realizes rack drives, to dally with hollow axle 8 at the section motor 1 not having rack rails, simultaneously, with engaging of axle drive gear 3, motor power is passed to axle drive gear 3 through the 4th gear 24, rotate around bearing shell 4 owing to bearing shell exists axle drive gear 3, power can not be transmitted, axletree 9 maintains former kinestate.
(2) when clutch 10 compresses, clutch 10, axle drive gear 3, bearing shell 4, ring parts 5 being fastened as a whole with axletree 9, motion and power are passed to axletree 9 by pressing of clutch 10 by such axle drive gear 3. In the section not having rack rails, axletree 9 band motor car wheel 11 moves, and rack rails meshing gear 7 is suspended on axletree 9 because not having rack rails. In the section having rack rails, axletree 9 band motor car wheel 11 moves, rack rails meshing gear 7 engages with rack rails simultaneously, but so have a problem that, rack rails meshing gear 7 moves it is difficult to ensure that the linear velocity of gear and the linear velocity of wheel are consistent with wheel 11 simultaneously, and axletree 9 so can be caused in motor process stuck for axletree 9.Therefore, need to loosen the clutch to allow motor 1 drive rack rails meshing gear 7 in the section having rack rails, rack rails meshing gear 7 transmit power and drive bogie motion. Compress clutch 10 in the section not having rack rails and ensure that axletree 9 transmits power, drive bogie motion, will not be so motor idle running.
