Detailed description of the invention
Provide specific embodiment below in conjunction with the accompanying drawings.
One embodiment of the present of invention is each to arrange a set of pair of roller under the driving force of each test base plate
Rotating mechanism, takes turns lower pair of roller rotating mechanism for explanation object, this pair of roller rotating machine with test base plate left drive
The structure reversing frame by double rollers of bearing chassis driving wheel, rotary middle spindle with around revolution central axis is constituted,
Bearing test chassis driving wheel 4 above double rollers 6, two ends are connected with reversing frame 5 by roller axle bearing 7；Return
The double roller 6 of pivoted frame 5 upper support, lower section is connected with trunnion axis by trunnion axis bearing block 12, and outside arranges row
Travelling wheel 11, inner side is connected with center steering axle 22 by central shaft bearing 17；Center steering axle 17 passes through the end
Portion's bearing 16 is fixing, and belt pulley 21 is installed on top with in frame 18, and bevel gear wheel 15 is installed in bottom, greatly
Installing on the left of bevel gear 15 and turn to bevel pinion 14, association bevel gear 19 is installed on right side；Double rollers 6 pass through roller
Sub-axle 8, small Spur gear 9, large straight gear 10 and trunnion axis 13 are connected with bevel pinion 14, complete power
Transmission；The center of center steering axle 22 and the centres of chassis steering spindle 3；Bevel pinion 14 is the most permissible
In original place rotation, it is also possible to drive reversing frame 5 to revolve round the sun around rotary middle spindle 22；Belt pulley 21 can be by front
After double roller rotating mechanisms center steering axle 22 linkage get up, it is ensured that the rotating speed of front-rear center gyroaxis 22
Identical；The bevel gear wheel 15 of double roller rotating mechanisms of left and right is linked by linkage bevel gear 19 by universal driving shaft 20
Get up, it is ensured that the rotating speed of left and right bevel gear wheel 15 is identical；Link permissible between bevel gear 19 and universal driving shaft 20
Dismounting easily, it is to avoid turn to due to left and right linkage bevel gear 19 when test base plate pivot stud condition test
The problem that difference is brought, it is ensured that being smoothed out of pivot stud test.
As it can be seen, be placed in by test base plate driving wheel 4 on double roller 6, pin friction lock 2, firing test
Chassis driving wheel 4, the most double rollers 6 meeting concomitant rotation, and then drive small Spur gear 9, large straight gear 10 to rotate,
Thus by trunnion axis 13 drive rotate bevel pinion 14 rotate, bevel gear wheel 15 will concomitant rotation, in
Heart gyroaxis 22 rotates together with bevel gear wheel 15, and belt pulley 21 ensures two pairs of rollers of before and after by V belt translation
Center steering axle 22 rotating speed of rotating mechanism is equal, and linkage bevel gear 19 is by about universal driving shaft 20 guarantee two
Bevel gear wheel 15 rotating speed of double roller rotating mechanisms is equal, the auger tooth of lower pair of roller rotating mechanism of the most each driving wheel
Take turns 15 rotating speeds the most equal, now can carry out the test of test base plate craspedodrome performance；Before changing, left and right drives
The rotating speed of wheel 4, releases the locking of friction lock, then by pinion rotation, bevel pinion 14 speed will occur
Change, and bevel gear wheel 15 is owing to by belt wheel 21 and the effect associating bevel gear 20, speed will keep
Constant, then bevel pinion 14 will drive reversing frame 5 to be rotated around center steering axle 22 by road wheel 11,
Meanwhile driving wheel also can turn round around its steering spindle 3, and velocity of rotation is identical with reversing frame 5 velocity of rotation,
Again because center steering axle 22 is concentric with the steering spindle 3 of chassis driving wheel, the most now can carry out test base plate and turn
To performance test.
An alternative embodiment of the invention is to change belt pulley 21 into sprocket wheel, changes belt into chain.Meanwhile,
Sprocket wheel can also be arranged under bevel gear wheel 15 by embodiments of the invention.And so on, at base of the present invention
On the premise of present principles is constant, on structure is arranged, the various changes made in structure, all will regard as
Inventive embodiment is demonstrate,proved.
