Abstract
The invention provides a road surface finishing machine including a frame (1) and multiple wheels (2). Multiple wheels (2) include two steering front wheels (9) and one or two driving wheels (10) provided on both sides, the driven and undriven steering front wheels (9) are supported on the frame (1), and they are suspended by pneumatic or hydraulic elements (11,12) communicated and connected together to unify the pressure.
Description
Technical field
The present invention relates to a kind of road-finishing machine that is fitted with wheel.
Background technology
The road-finishing machine that is fitted with wheel usually removes to have also to have one or two the driving wheel that is in afterbody (every side one or two) and is in anterior every side, and is in the deflecting roller that loads below the hopper that desire lays material.
In order to obtain good self-leveling performance (this performance is necessary to laying horizontal surface and load being uniformly distributed on the deflecting roller), be well known that: under situation with the road-finishing machine of four deflecting rollers, be under the situation of two deflecting rollers of every side, each deflecting roller that is in a side respectively is installed on one in the connection rocking arm that vertically works with respect to travel direction.
When following when sailing the direction pavement roughness, utilize and also can produce gratifying level compensation at the rocking arm that travel direction works.On being transverse to travel direction, exist when having the out-of-flatness of certain-length, two deflecting rollers that this out-of-flatness can allow to be contained in this rocking arm one side are positioned on the horizontal plane of this out-of-flatness place, and the driving wheel of two deflecting rollers of opposite side and afterbody is positioned on the standard water plane, therefore, (this rocking arm can bring the problem that takes up space there not being a horizontal rocking arm, and make complex structure, cost increases) time, not too satisfied transverse horizontal compensation only had.The deflecting roller that is in the recess can be to a certain extent more or less by off-load according to the torsional strength of this machine for trimming frame, up to this deflecting roller and ground no longer exist any contact this limit situation till.When these deflecting rollers during by off-load, the deflecting roller that is in opposite side but is subjected to same degree the effect of bigger load.
If this deflecting roller oneself is fitted with drive unit from now on, this will cause the deflecting roller of this off-load to skid inevitably, and this not only produces traction problems but also can form pace inhomogeneous (reason is that the road pavement compacting is inhomogeneous).In addition, the skid ground of deflecting roller under this is taken turns of (wheel fast idle) can make this rubber wheel of taking turns produce huge wearing and tearing when firm, and when the ground under this is taken turns is soft,, this deflecting roller make the road surface produce extra out-of-flatness in the process of moving because of making the road surface in this excircle district of taking turns be subjected to the high pressure effect.These out-of-flatnesses just make the driving process instability.
Even also there is similar problem when having horizontal rocking arm, reason is that this deflecting roller bears powerful lateral pressure during this rocking arm rotation.
Summary of the invention
The objective of the invention is for a kind of road-finishing machine is provided, this machine is fitted with a plurality of wheels, also has identical load even if wherein can guarantee all driven deflecting rollers on the ground of injustice.
The objective of the invention is to realize by a kind of like this road-finishing machine, it has a chassis and wheel dynamic formula running gear, this is taken turns the dynamic formula running gear and comprises at least two steering front wheels and one or two driving wheel in each side, wherein at least some deflecting rollers are driven, it is characterized in that, all driven deflecting rollers separately by be bearing on the chassis pneumatic-or hydrodynamic unit suspended, these are pneumatic-or hydrodynamic unit connect for connecting ground mutually for the purpose of the pressure balance.
Description of drawings
The present invention is described in further detail by the accompanying drawing illustrated embodiment below, in the accompanying drawing:
Fig. 1 is the lateral view of a road-finishing machine;
Fig. 2 and 3 is depicted as the single deflecting roller suspension arrangement of road-finishing machine shown in Figure 1.
The specific embodiment
Illustrated road-finishing machine comprises a chassis 1 that has wheel dynamic formula running gear 2, the front portion on this chassis 1 has a hopper 3, and have a screw spreader 4 at afterbody, a mixed material that is used for remaining to be laid is transported to the zone of this screw spreader 4 by a haul vertical shaft by hopper 3 conveyer belt (can't see among the figure) is set between this hopper 3 and screw spreader 4.The superstructure that above this haul vertical shaft, has road-finishing machine.
Be used for floating laying and wait that the laying plate 5 of laying mixed material is hinged on this chassis 1 by pull bar 6.This laying plate 5 is in the back of this screw spreader 4 along laying direction, and comprises a substrate 7 and drawing plate 8.But the described relatively substrate side direction of these drawing plates 8 is also stretched independently of each other.This substrate 7 separates in the centre usually, and the two halves of this substrate can tilt each other so that laterally form a ridge shape shape with respect to this laying direction.This laying plate 5 comprises that worthily one is combined with the combiner of ramming and flatter, and this combiner mixed material that remains to be laid in its front that screw spreader 4 can be paved is compacted into one deck and carries out smooth to its aspect.
Wheel dynamic formula running gear 2 comprises at least two steering front wheels 9 and one or two driving wheel 10 in each side.Have at least part to be driven in these deflecting rollers 9, these deflecting rollers 9 (preferably also comprise can not driven deflecting roller 9) suspend by the pneumatic or hydrodynamic unit that is bearing on the chassis separately, these pneumatic or element connection formula mutually connections of surging are to realize pressure balance.Pressure cylinder, accumulator, rubber bellows or like all can be considered as pneumatic or hydrodynamic unit.
In such a way, can guarantee that all are driven with not driven deflecting roller 9 and have identical used load,, can not produce traction problems like this thereby pace is inhomogeneous even also be so at Uneven road.
As from can finding out Fig. 2 and 3, (compressed air or fluid power) pressure cylinder 11 this deflecting roller 9 that is used for suspending individually is set, these pressure cylinder 11 vertical fixing are on this chassis 1 and accommodate a piston rod 12; One horizontally disposed U-shaped yoke 13 is fixedly attached on the end of this piston rod 12 that stretches out pressure cylinder 11 downwards.Be welded on this yoke 13 is a bifurcated drag-link-arm 14 that is used to turn to.One hydraulic drive motor 15 centrally is arranged in this yoke 13, and the blue in accordance with the law connected mode of deflecting roller 9 is connected on this motor.One pressure-equalizing pipe 17 links with the inner chamber 16 of pressure cylinder 11, and this pressure-equalizing pipe 17 is interconnected with other pressure-equalizing pipe 17 of other pressure cylinder 11 of other deflecting roller 9 usefulness.
