Especially, if at least one in each wheel driver has parallel connected hydraulic axial piston motor, can obtain very simple proposal so, the conditioning equipment of the tractive force that is used for relevant wheel is provided, by this conditioning equipment, in the process of rolling, the mode of carrying out around the moment of equipment vertical axis effect with local equalize at least influences the distribution of tractive force.
But, also might use the transmission mechanism that has speed changer by at least one wheel driver on equipment one side, this speed changer is different with the speed changer of the transmission mechanism of at least two wheel drivers of the wheel of the opposite side of vehicle, in the process of rolling, the moment around the vertical axis effect of device is proceeded to the compensation of small part, perhaps at least one wheel diameter on equipment one side is different from the wheel diameter of the wheel on the opposite side of equipment, the moment around the vertical axis effect of device is proceeded to the compensation of small part in the process of rolling.But, in these cases, the different tractive force of wheel are held in the transportation of equipment, thereby can make straightaway be subjected to influencing unfriendly under the kind situation of back.Yet because the process of equipment transportation is shorter, this influence is less.
Can obtain more purposes, advantage and the embodiment of the embodiment of the invention in the explanation hereinafter.
Description of drawings
Embodiment among the present invention with reference to the accompanying drawings describes.
Fig. 1 schematically shows the plan view of the self-propelling instrument that is used for rolling road surface.
Fig. 2 schematically shows the drive system of equipment shown in Figure 1.
The specific embodiment
The self-propelling instrument that is used for rolling road surface shown in the drawings comprises vertical adjustable chassis 1, that this chassis has is exercisable, have before to the back to the walking mechanism of wheel 2 and hold driver element 3, Diesel engine for example, this motor driven is used for the pump 4 of hydraulic oil, for example axial poiston pump.What be connected in driver element 3 equally is to roll unit 5, this rolls the unit and comprises milling roller 7, this milling roller is horizontal expansion with respect to direct of travel, this milling roller also is provided with and rolls cutter 6, the width of this milling roller is off-centered less than the width of equipment and with respect to equipment, and milling roller is mutually concordant with the right side of equipment in this case.
Apparatus shown comprises the off hind wheel 2 of outside swing, thereby when trailing wheel 2 was outwards swung, the axle of trailing wheel 2 and the axle of milling roller 7 were positioned at vertical plane in fact.In transportation, and roll in the process concordant, for example along the edge or the analogue of curb, off hind wheel 2 is inwardly swung, this be since when latter event off hind wheel otherwise can can't on the road surface, travel.
In grinding operation, equipment moves on the road surface, applies all tractive force by wheel 2 ,-along the direction of arrow 8, the rotation of milling roller 7 is opposite with direct of travel.Because milling roller 7 departs from center arrangement, so equipment is applied with the power of corresponding off-centre along arrow 9 directions, thereby obtain around the moment (perpendicular to the paper plane of Fig. 1) of equipment vertical axis 10-along between the sagittal plane, center 13 of the central longitudinal plane 12 of the direction of arrow 11-correspond essentially to equipment and milling roller 7 apart from d (quality of the equipment that less is evenly distributed bring usually influence less), this moment tends to make the equipment can't be by straightaway.
