Description
Technical field
The invention belongs to track traffic check implement technical field, relate to a kind of framework dolly that is used for passenger vehicle concretely.
Background technology
Main body framework for passenger vehicle all need detect correlated performance; Because framework is as large-scale framing member; Move to relevant detection equipment place during framework maintenance for ease, need framework is positioned on the dolly, make framework move to another position from a platform position quickly and easily.And for saving space, the framework space for maintenance is in a rectangular place, and the framework dolly just need move a circle along track, and the inner track radius has only about 3 meters.No matter existing dolly is to move in orbit or on the road surface, move, and its turning principle generally is that front axle (axle that connects the front two-wheel) rotates with cartridge, perhaps front axle, rear axle (axle that connects the back two-wheel) is coupled together and rotates with cartridge.Also have the light-duty dolly that moves on a kind of road surface, though four wheels all are independently, also can before and after rotate and horizontally rotate, do not have contact between wheel, turn and dumb.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, turning is used for the framework dolly of passenger vehicle flexibly.
Technical scheme of the present invention is following:
A kind of framework dolly; Comprise vehicle frame body, first wheel, second wheel, the 3rd wheel and the 4th wheel; Said first wheel, second wheel, the 3rd wheel and the 4th wheel all mainly are made up of wheel body, vehicle wheel frame and link span; Can relatively rotate between wherein said vehicle wheel frame and the said link span, be connected with longitudinal tie on the said vehicle wheel frame, be hinged with first lateral connecting rod between the longitudinal tie of said first wheel and the 3rd wheel; Be hinged with second lateral connecting rod between said second wheel and the 4th wheel, said vehicle wheel frame is fixed on the said vehicle frame body.
Adopt said structure, four wheels are connected on the trolley frame.First wheel and two wheels of the 3rd wheel are drawn with longitudinal tie respectively, be connected with the longitudinal tie hinge with lateral connecting rod, three pull bars form a leverage, and two-wheeled can only rotate simultaneously like this.Also adopt in the same way between second wheel and the 4th wheel.Turn flexibly and the conformability when having guaranteed that four wheels are turned.
Be rotationally connected through second bearing between said vehicle wheel frame and the said link span, also be provided with between wherein said vehicle wheel frame and the said link span and be connected locating dowel pin.
Said vehicle wheel frame is provided with wheel shaft, and said wheel body is sleeved on the said wheel shaft through clutch shaft bearing.
The dolly wheel is four independently wheels, and each wheel is except that can rotating along axis horizontal separately the rotation of front and back.The front and back of wheel are rotated through the clutch shaft bearing that is installed in each wheel and are realized; The rotational of wheel realizes through second bearing that is installed on the wheel top.
Said link span is provided with connecting bore, is fixed on the said vehicle frame body through this connecting bore.
The turning center line of said first wheel and the 3rd wheel steering line of centres and second wheel and the 4th wheel intersects at same Turning radius center.
The wheelbase of inboard wheel and the wheelbase of outboard wheels are inequality.Two wheel center lines of front axle and two wheel center lines of rear axle are in stability and the conformability of guaranteeing to turn on the track turn radius.
Said clutch shaft bearing is selected single direction thrust ball bearing for use.
Said second bearing is selected deep groove ball bearing for use.
Beneficial effect: the present invention is simple in structure, practical, improved the stability and the conformability of turning greatly.
