Referring to Fig. 1-Fig. 4, a kind of single-wheel hauling ability proving installation, comprise stand 1, parallel four connection rod set 3, outside framework 4, double-act-ing hydraulic J-Horner 5, inner frame 6, longitudinal sensor 7, survey torque sensor 8, side direction sensor 9, vertical sensor 11, side direction preloading spring 10, vertical preloading spring 12, detected tyre 13, bearing seat 14, oil motor 15, minor sprocket 16, chain 17, hinge wheel 18, transmission shaft 19.Setting detected tyre 13 working direction is X-axis, and axial direction is Y-axis, is the coordinate system of Z axis straight up, and the geometric center that the O point is detected tyre 13 is set up XOY, XOZ, tri-planes of YOZ thus.
A kind of single-wheel hauling ability proving installation, the stand 1 be welded by square steel is arranged on soil box 2, and can do constant speed along soil box 2 orbital directions and move under the drive of soil box 2 drive motor.Parallel four connection rod set 3 one ends are connected with stand 1 one side girders by two pin joints, and the other end passes through two pin joints and is connected with outside framework 4, and four pin joints are in the XOZ face, and the hinging pin shaft center line is vertical with this face; Double-act-ing hydraulic J-Horner 5 one ends are articulated on stand 1 crossbeam, and the other end and outside framework 4 tops are hinged, and double-act-ing hydraulic J-Horner 5 central axis are on the XOZ face, and two hinging pin shaft center lines are vertical with this face.Outside framework 4 and inner frame 6 are connected with a pair of vertical preloading spring 12 by a pair of longitudinal sensor 7, survey torque sensor 8, a pair of side direction sensor 9, a pair of side direction preloading spring 10, an a pair of vertical sensor 11.Detected tyre 13, bearing seat 14, oil motor 15 are installed, minor sprocket 16, chain 17, hinge wheel 18, transmission shaft 19 on inner frame 6.
Referring to Fig. 2, a pair of longitudinal sensor 7 is symmetrically arranged in XOZ face both sides, and the center line of longitudinal sensor 7 is all on the XOY face; A pair of side direction sensor 9 is symmetrically arranged in YOZ face both sides, and the center line of side direction sensor 9 is all on the XOY face, the position of the corresponding side direction sensor 9 of opposite side that a pair of side direction preloading spring 10 is arranged in respectively detected tyre 13; Survey torque sensor 8 and vertically be arranged on the XOZ face, and survey torque sensor 8 lower end ball pivot contacts on the XOY face; A pair of vertical sensor 11 is symmetrically arranged in XOZ face both sides, and the center line of vertical sensor 11 is all on the YOZ face, and a pair of vertical preloading spring 12 is arranged in respectively under vertical sensor 11 accordingly.
In longitudinal sensor 7, survey torque sensor 8, side direction sensor 9, vertical sensor 11, each ball pivot of each sensor two ends connects a hook, and a side hook is installed on inner frame 6, and the opposite side hook is installed on outside framework 4; Each preloading spring two ends in side direction preloading spring 10, vertical preloading spring 12 respectively articulate a hook screw rod, and two ends hook screw flight rotation direction is contrary, on each hook screw rod, coordinates nut seat is installed.Equally, a side nut seat is installed on inner frame 6, and opposite side is installed on outside framework 4.
Referring to Fig. 3, oil motor 15 is installed on inner frame 6 side steel plates, and the motor output shaft of oil motor 15 is equipped with minor sprocket 16, under crossbeam installation shaft bearing 14, transmission shaft 19 is installed on bearing seat 14 inner bearings; Transmission shaft 19 1 ends are installed hinge wheel 18, and the other end connects detected tyre 13 wheel hubs; Chain 17 connects minor sprocket 16, hinge wheel 18.
On transmission shaft 19, speed probe is installed, and the upper all the sensors of device all connects computing machine by data collecting card; Computing machine can change the on-load pressure of double-act-ing hydraulic J-Horner 5 and the rotating speed of oil motor 15 in real time by controlling peripheral hydraulic circuit.
Computing machine is opened and each road sensing data of Real-time Collection.Control double-act-ing hydraulic J-Horner 5 piston rod indentations to promote outside framework 4, inner frame 6 and to be installed on the assembly on inner frame 6, make detected tyre 13 break away from soil in soil box 2.Control double-act-ing hydraulic J-Horner 5 piston rods static, turn respectively that preloading spring is vertical to regulate, the side direction pretightning force, making a pair of vertical sensor feedback data is zero, and the feedback data of a pair of side direction sensor reaches half of range.
