With reference to Fig. 2, owing to being threaded engagement between the studdle 12 of adjustable supporting and the base pole of base for supporting 13, studdle 12 can be driven to rotate by the setting nut 12-1 on rotary support screw rod 12, to make studdle 12 flexible in the base pole of base for supporting 13, thus to realize the adjustment of adjustable supporting bearing height.Simultaneously owing to being the structure that is connected between studdle 12 and support bar 11-2, so during rotary support screw rod 12, supporting 11 can not rotate, and therefore can carry out the adjustment of bracing or strutting arrangement height when automobile is placed on adjustable supporting.
The adjustment of the longitudinal bracing position of universal body mode experiment supporting device:
With reference to Fig. 7, by controlling the rotating forward of longitudinal mobile motor 5, drive the rotating forward vertically moving screw rod 6, owing to vertically moving screw rod 6 and No. 1 longitudinal carrier 16-1, No. 2 longitudinal carrier 16-2 are threaded, and vertically move No. 1 longitudinal carrier 16-1 that screw rod 6 passes, the hand of spiral of the screw thread on No. 2 longitudinal carrier 16-2 is contrary, so when vertically moving screw rod 6 and rotating forward, vertically move screw rod 6 and can allow No. 1 cross slide way 2-1 and No. 2 cross slide way 2-2 move toward one another, realize the distance between adjustment No. 1 cross slide way 2-1 and No. 2 cross slide way 2-2, keep the center of gravity of universal body mode experiment supporting device between No. 1 base 1-1 and No. 2 base 1-2 simultaneously.In like manner, control longitudinal mobile motor 5 to reverse, vertically move No. 1 cross slide way 2-1 and No. 2 cross slide way 2-2 of screw rod 6 control by oppositely movement, realize the distance between adjustment No. 1 cross slide way 2-1 and No. 2 cross slide way 2-2, keep the center of gravity of universal body mode experiment supporting device simultaneously between No. 1 base 1-1 and No. 2 base 1-2.
The adjustment of the cross-brace position of universal body mode experiment supporting device:
With reference to Fig. 9, by controlling the rotating forward of transverse mobile motor 9, drive the rotating forward of transverse shifting screw rod 7, due to transverse shifting screw rod 7 and No. 1 horizontal support 14-1 be fixed on No. 1 base for supporting 13-1, No. 2 horizontal support 14-2 be fixed on No. 2 base for supporting 13-2 are threaded, and the hand of spiral of screw thread on No. 1 horizontal support 14-1 and No. 2 horizontal support 14-2 passing of transverse shifting screw rod 7 is contrary, so when transverse shifting screw rod 7 rotates forward, transverse shifting screw rod 7 drives No. 3 adjustable supportings and No. 4 adjustable supporting move toward one another, realize the distance between adjustment No. 3 adjustable supportings and No. 4 adjustable supportings, keep the center of gravity of universal body mode experiment supporting device to be positioned at the middle part of No. 2 cross slide way 2-2 simultaneously.In like manner, control transverse mobile motor 9 to reverse, drive the reversion of transverse shifting screw rod 7, transverse shifting screw rod 7 drives No. 3 adjustable supportings and No. 4 adjustable supporting oppositely movements, realize the distance between adjustment No. 3 adjustable supportings and No. 4 adjustable supportings, keep the center of gravity of universal body mode experiment supporting device to be positioned at the middle part of No. 2 cross slide way 2-2 simultaneously.
Threaded hole is had owing to supporting on 11, so when vehicle body is higher, any one in one side of vehicle body and four bracing or strutting arrangements can be connected by bolt nut structure, and support can be taken over a business 11 with studdle 12 by trip bolt 15 and be connected, ensure the stability of vehicle body in process of the test with this.Meanwhile, the top end face of other tripartite's adjustable supportings places air spring 10, to ensure the air supporting of vehicle body.
