Description
Technical field
The present invention relates to trailer components, more particularly to a kind of accurate display axial load rack wheel.
Background technology
Trailer is applied to highway, the operation of removing obstacles of urban road.By chassis, hoisting apparatus, lift draw-gear, liquid
Pressure system, electric-control system, car body and tool box etc. constitute, with lift by crane, pull and lift traction etc. multiple function.Precision display
Axial load rack wheel is one important component of trailer, and existing rack wheel often occurs that adjustable shelf is come off or support wheel load is shown
There is deviation, make the shortcomings of carrying is too high to produce damage.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of novel accurate display axial load simple in construction
Rack wheel.
In order to achieve the above object, a kind of accurate display axial load rack wheel of the present invention, mainly by fixed outer tube, activity
Truck parts, screw mandrel, spring, protective case, load value cup, stage clip, load indicate dome, spring catch, handle portions point, wheel,
Thrust bearing, pad composition,
It is characterized in that：Each part is connected together by bearing with the spring catch, is installed successively above the screw mandrel
The thrust bearing, the spring, the protective case, the pad, the fixed outer tube, load value cup, the pressure
Spring, the load indicate dome, the handle portions point, and the screw mandrel is connected to the handle portions point by the spring catch
Together.
The movable truck parts are mainly made up of screw, inner sleeve, left support plate, right support plate, and the screw passes through
Riveting is fixed on the inner sleeve, and the left support plate, the right support plate weld together with the inner sleeve, the silk
It is female to be together by a threaded connection with the screw mandrel.
Its course of work is：Precision is shown that axial load rack wheel is fixed on trailer by connector, works as motor vehicle
Before the motion of drive trailer, handle portions point should be rotated first, is connected by screw mandrel with screw, movable truck parts is received completely
Hold together, during gathering, in fixed outer tube lower ending opening insertion activity wheel carrier left-and-right supporting plate, play fixed locking effect, prevent
Only truck parts are rotated with fixed outer tube；When motor vehicles parking need to unload trailer, should rotate hand handle makes adjustable shelf in screw mandrel
Moved down with nut effect, after wheel contacts to earth firmly, be rotated further hand making wheel carry trailer weight completely, at this moment pass through wheel
Under bear external force effect, spring is transferred the force to by screw mandrel, stage clip is compressed therewith, while load value cup and load
Dome relative distance increase under stage clip effect is indicated, incrementss are equal to amount of spring compression.The coefficient of elasticity designed according to spring
With load value cup axle to indicating that numerical value is consistent, rack wheel now born axial load situation is accurately reflected.
The advantage of the invention is that：By spring properties, realize that load is accurately shown on rack wheel product, this structure structure
Think ingenious, simple novelty.Fixed outer tube lower end slot-type openings, after rack wheel gathering in insertion adjustable shelf left-and-right supporting plate, rise
Rack wheel movable wheel carrier partial exfoliation is prevented during to movement of vehicle, the structure uses self-locking mechanism, solid and reliable, structure letter
It is single novel.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As illustrated, a kind of accurate show axial load rack wheel, mainly by fixed outer tube 1, movable truck parts 2, screw mandrel 4,
Spring 5, protective case 6, load value cup 7, stage clip 8, load indicate that dome 9, spring catch 10, handle portions divide 11, wheel 12, thrust
Bearing 16, pad 17 are constituted,
It is characterized in that：Each part is connected together by bearing with the spring catch 10, is installed successively in the top of screw mandrel 4
The upper thrust bearing 16, the spring 5, the protective case 6, the pad 17, the fixed outer tube 1, the load value
Cup 7, the stage clip 8, the load indicate dome 9, the handle portions points 11, by the spring catch 10 the screw mandrel 4 and
The handle portions point 11 link together.
The movable truck parts 2 are mainly made up of screw 3, inner sleeve 13, left support plate 14, right support plate 15, described
Screw 3 is fixed on the inner sleeve 13 by riveting, the left support plate 14, the right support plate 15 and the inner sleeve 13
Weld together, the screw 3 is together by a threaded connection with the screw mandrel 4.
Its course of work is：Precision is shown that axial load rack wheel is fixed on trailer by connector, works as motor vehicle
Before the motion of drive trailer, handle portions point 11 should be rotated first, is connected by screw mandrel 4 with screw 3, makes movable truck parts 2 complete
Complete to draw in, during gathering, the fixed lower ending opening insertion activity wheel carrier left support plate 14 of outer tube 1 is with right support plate 15, rising
To fixed locking effect, prevent truck parts from being rotated with fixed outer tube 1；When motor vehicles parking need to unload trailer, it should rotate
Hand handle makes adjustable shelf be moved down in screw mandrel 4 with nut effect, after wheel 12 contacts to earth firmly, and being rotated further hand handle makes wheel 12 hold completely
Trailer weight is carried, under at this moment being acted on by the bear external force of wheel 12, spring 5 is transferred the force to by screw mandrel 4, makes stage clip 8
Compress therewith, while load value cup 7 indicates the relative distance increase under the effect of stage clip 8 of dome 9 with load, incrementss are equal to bullet
The decrement of spring 5.The coefficient of elasticity designed according to spring 5 axially indicates that numerical value is consistent, accurately reflects support with load value cup 7
Take turns now born axial load situation.
