Abstract

The utility model discloses an improved folding automobile chassis maintenance vehicle, which is characterized in that a cartwheel steering mechanism composed of rotating wheel frames, a pushing and pulling transmission rod, a transmitting and swinging rod, and a steering handle is arranged on the base of the vehicle frame. The transmitting and swinging rod rotate clockwise or counterclockwise by rotating the steering handle, and four rotating wheel frames driven by the pushing and pulling transmission rod cause a small wheel to turn left or turn right synchronously. In addition, an angle regulating mechanism for the working platform is composed of a screw rod, a nut rocking handle and a shaft sleeve and is arranged on a sliding frame of the working platform. The utility model has the advantages that the steering is convenient, the working platform can be adjusted, and the operation of the automobile chassis assembling and disassembling is very laborsaving, accurate, convenient and quick.

Description

A kind of improved foldable vehicle maintenance chassis car

The utility model relates to the maintenance car that a kind of chassis assembly that services a car is used, particularly a kind of improved maneuverable foldable vehicle maintenance chassis car, can be used for the support chassis gearbox, assemblies such as power transmission shaft and backteeth bag can be used as conveniently assemble and disassemble and support the usefulness of the self-powered platform of these parts.

When the auto repair personnel service a car assemblies such as chassis in mounting or dismounting, three above jack of normal employing withstand a workbench, several jack adjustable heights are difficult to be consistent, be difficult to the control parts of installing and removing stability and accuracy, also handy hand is pickaback lifted sometimes, very hard, make maintenance operation time-consuming, dangerous and inefficiency.For a change this situation, I once designed a kind of maintenance chassis car with folder function, the technical characterstic of this maintenance car is to include to be provided with one between workbench and the vehicle frame base that universal wheel is housed and to constitute a spiral lifting mechanism by positive and negative tooth screw mandrel, the up and down nut that cooperates with this screw mandrel, two upper and lower movable branching rods and two batter posts that play the main backstop effect, wherein positive and negative tooth screw mandrel hold the middle position that is fixedly mounted on above-mentioned two batter posts by top chock and step end to end; Wherein two last its lower ends of movable branching rod are hinged with following traveling nut respectively, its upper end is hinged with the long sheath axle that is contained in the workbench frame skeleton respectively, two its upper ends of following movable branching rod are hinged with last traveling nut respectively in addition, its lower end is hinged with base respectively, wherein two its upper ends of support batter post are hinged with workbench respectively, and its lower end is hinged with the vehicle frame base respectively.Above-mentioned maintenance car has laborsaving effect easily when parts such as dismounting chassis assembly, but discovery on probation, vehicle frame base dress is universal wheel, when being installed to the chassis gearbox on the automobile, make clutch spindle aim at clutch disc keyway ditch, universal wheel is difficult to control accuracy, and left and right sides error is big; Adding between the not gentle workbench of upper ground surface and the last movable branching rod is being movably hinged of a certain fixed position, and makes workbench inconvenience be adjusted to the required dismounting angle angle of level (tilt or).Below all had a strong impact on the mounting or dismounting efficient of chassis assembly.

The purpose of this utility model is on the basis of prior art, design a kind of improved foldable vehicle maintenance chassis car, make it when dismounting services a car chassis assembly, have laborsaving, quick, turn to conveniently, the workbench angle adjustable is installed the effect that control is easily grasped in the degree of accuracy.

The utility model is to adopt following technical scheme to realize: it still is made of the parts of above-mentioned existing collapsible maintenance chassis car, it is characterized in that: a, between the front and back trundle under the vehicle frame base, be provided with one successively by four runner supports, four push-and-pull drive links, the base wheel steering mechanism that the steering tiller of transmission fork and the swing of control transmission fork constitutes, wherein be movably hinged with the vehicle frame base respectively with an end of four runner supports of trundle interlock separately, the other end is movably hinged with an end of four push-and-pull dwangs respectively, the other end of push-and-pull drive link is movably hinged with the two ends of transmission fork respectively again, wherein steering tiller is fixedlyed connected with the middle part of transmission fork, and the middle part centre of transmission fork is connected into the hank fulcrum with vehicle frame base moveable hinge, with hand left-right rotation steering tiller, can make the transmission fork clockwise or rotate counterclockwise around hinged point, from and do swing by driving four runner supports respectively with the hinged four push-and-pull drive links in its two ends, four trundles turn to respectively synchronously to the left or to the right before and after finally making, thereby reach the purpose that allows maintenance car turn to according to the mounting or dismounting needs easily.B, on the frame skeleton of workbench, be provided with one by screw mandrel, the workbench hue angle mechanism that nut rocking handle and axle sleeve constitute, wherein be positioned the lateral margin of workbench frame skeleton with this screw mandrel tail end nut engaged rocking handle, the axle sleeve of fixedlying connected with the other end of screw mandrel is to be actively socketed on the long sheath axle that connects with last movable branching rod, and the two ends of long sheath axle are to be movably arranged in the long slot bore of workbench two frame skeletons, when platform is increased to working depth, the nut rocking handle is shaken in rotating, can make screw mandrel and axle sleeve front and back mobile a little, from and can drive hinged with it two by long sheath axle and go up the movable branching rod front and back and swing a little, its support angle is changed a little, make workbench also tilt up or down, reach and adjust workbench, realize fast installing and removing exactly treating Awaiting Parts to required setting angle.

Compared with prior art, it is good that its base wheel steering mechanism of the utility model maintenance car handles directed travelling performance with steering tiller, and front and back wheel all participates in turning to, and steering angle is big, maintenance car can be travelled by horizontal 45 degree, make when the installation chassis gearbox more convenient, accurate, quick.This be former universal wheel can't be obtained.And workbench is furnished with hue angle mechanism, makes maintenance work more seem convenient easily quick.

Following accompanying drawing is a kind of embodiment of the present utility model, wherein:

Fig. 1 is the side structure schematic diagram (workbench has risen to working depth) of this chassis maintenance car.

Fig. 2 is mounted in the structural representation of the wheel steering mechanism under the vehicle frame base.
