Description
Technical field
Wheel steering, multi-axle steering.
Background technology
Tie rod linkage, steering deviation be present to top crank mechanism, deflection wheel formula multi-axle steering mechanism is used between bridge
The way that all steeraxles connect is introduced more multi-steering deviation by connecting rod.
The content of the invention
The present invention keeps the angle relation between the wheel of each steeraxle or so two using mechanical component, is linked with rack-and-pinion
All steeraxles simultaneously keep the steering geometry relation between each steeraxle.The present invention makes each wheel axis be turned in ideal in plane
Projection is met at a bit.
Brief description of the drawings
The schematic diagram of mechanism example 1 of the single steeraxles of Fig. 1(Spherical hinge letter is depicted as common hinge)
The schematic diagram of mechanism example 2 of the single steeraxles of Fig. 2(Spherical hinge letter is depicted as common hinge)
The schematic diagram of mechanism example 3 of the single steeraxles of Fig. 3(Spherical hinge letter is depicted as common hinge)
The schematic diagram of mechanism example 4 of the single steeraxles of Fig. 4(Spherical hinge letter is depicted as common hinge)
Specific implementation method
It is required that it is that the corner of steering wheel is converted into bar through transmission device when mechanically connecting between steering gear and deflecting roller(1)Lead on edge
The linear motion of rail;When being connected between steering gear and deflecting roller for on-mechanical, Hydraulic Elements or motor control bar(1)It is straight along guide rail
Line moves.Bar(1)Can be connected damper, servomechanism, back-moving spring.Bar(1)On be mounted with a pair of swinging blocks(2、3), swinging block
Pivot is with bar(1)Motion, and swinging block has certain space moved up and down, there is hole in center, can turn to plane significantly
Swing and can swing up and down(Similar to the motion of Tank Gun Barrel).Rocking arm(4、5)One can be in swinging block(2、3)In interior hole
Slided along the direction in hole, rocking arm can be directly as knuckle arm, i.e. the rotation axis of rocking arm is main pin axis;Or preferable
Turn in plane, bearing pin rotation of the rocking arm in frame, the pivot of rocking arm and the spherical hinge of one head(Or common hinge)
The line of pivot, the line at pivot and stub center of rocking arm, knuckle arm spherical hinge pivot with
Line, the drag link at stub center(6、7)The line of two hinge forms transmission parallelogram, makes corner and the steering of rocking arm
The corner of joint arm is consistent.Can not be too small in view of the minimum transmission angle of linkage, vehicle limit on the left corner and limit on the right-right-hand limit
Corner is unequal, and when it is 0 that vehicle straight trip, which turns to wheel angle, transmission parallelogram is designed to certain adjacent side angle,
Preferably make wheel be located at limit on the left corner and parallel four-bar linkage during limit on the right-right-hand limit corner drive line angle it is roughly equal.Preferable
Turn in plane, when it is 0 that vehicle straight trip, which turns to wheel angle, the rocking arm of vehicle side(4)Pivot B and swinging block
(2)Pivot E line and bar(1)Acute angle ∠ AEB folded by axis AE, there is tan ∠ AEB=2L/M, in formula:In M-stub
Heart distance, the distance of the straight line parallel to steeraxle axis where L-steeraxle axis to turning center;The rocking arm of opposite side
(5)Pivot C, sliding block(3)Pivot F and rocking arm(4)Pivot B, swinging block(2)Pivot E along hang down
Directly in bar(1)The straight line OD of axis arranges into axial symmetry.If movement interference planar occurs for two connecting rods, they can be designed
Moved in two adjacent parallel planes.During actual arrangement, plane where steering mechanism can the hypsokinesis with reverse caster, rocking arm
The bearing pin of pivot can the introversion with Kingpin inclination.The projection for wanting to turn in plane when all deflecting roller axis are resonable is handed over
When some, the bar of all steeraxles(1)Between displacement it is proportional, can be in bar(1)Upper arrangement height can not wait
Linkage rack, with the bar of gear not of uniform size and corresponding steeraxle(1)On linkage rack correct engagement to ensure each turn
To the bar of bridge(1)The correct proportions relation of displacement, foregoing all gears can be fixed in one or more rotating shafts(Rotating shaft is with turning
Between centers gear or Chain conveyer etc. maintain the correct proportions relation of corner), shaft axis need to avoid semiaxis wobble area and difference
The parts such as fast device.
