The utility model manufacturing is simple, and is easy to maintenance, and cost is not high, and can overcome and make land used claim whole shortcomings that the measured automobiles load carrying ability is brought.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present utility model.
Fig. 2 is skate part figure in addition.
Fig. 3 is the A-A view.
Fig. 4 is the castellated shaft front view.
Fig. 5 is schematic circuit diagram of the present utility model.
With reference to Fig. 1, the outside that hitch (1) is installed in automotive frame is positioned at the top of automobile leaf spring first half near the middle part, and the carload measuring device is contained on the hitch (1).Behind the lorry loading, under the effect of load, automobile leaf spring generation deformation, produce longitudinal travel between automobile leaf spring and the automotive frame, when needs measured automobiles load carrying ability, earlier with automobile parking in more smooth place, a place, energized switch (27) then, at this moment, the two ends of the coil on the electromagnet (17) are connected with positive source and power cathode respectively.The end face of electromagnet (17) generates an electromagnetic field.Under the effect of electromagnetic force, wedge type iron block (15) drives the resistance that castellated shaft (7) overcomes spring (10), connection ear (25) with the castellated shaft guide frame is that rotate to electromagnet (17) direction in the axle center, make and skate (18) that castellated shaft (7) connects firmly together contacts with resistance (19), the rotatable steamboat (13) of castellated shaft (7) lower end with contact at automobile leaf spring, castellated shaft (7) is done with automobile leaf spring together with rotatable steamboat (13) on its lower end and is vertically moved, the skate (18) that the vertically moving of castellated shaft (7) makes and castellated shaft (7) connects firmly resistance is together also done and is vertically moved, and the resistance in the circuit changes thereupon.This variation of resistance is directed at that electric current changes in the circuit, and the variation of the electric current of this reaction load carrying ability shows by load test indicator (28).Because behind the lorry loading, also can produce displacement between detection position on the automobile leaf spring and the automotive frame along the auto body fore-and-aft direction, so, in castellated shaft (7) lower end a rotatable steamboat (13) is housed, when between detection position on the automobile leaf spring and the automotive frame when the auto body fore-and-aft direction produces displacement, steamboat (13) rolls, and is in plumbness at any time to guarantee castellated shaft (7), to guarantee survey precision.Because the contact (23) on the spiral shell nurse (6) joins with positive source, spring leaf (4) links to each other by the end of lead with overload indicator lamp (29), and the other end of overload indicator lamp (29) links to each other with power cathode, when the lorry loading amount is overweight, longitudinal travel increases between automobile leaf spring and the automotive frame, the spiral shell nurse of installing on castellated shaft (7) upper end (6) contacts with spring leaf (4), the circuit of overload indicator lamp (29) connects system, overload indicator lamp (29) is bright, reminds chaufeur to note.In addition, according to different vehicles, can be by adjusting the load carrying ability that spiral shell nurse (6) limits automobile.
When not needing the measured automobiles load carrying ability, source switch (27) is opened, electromagnet (17) is gone up power supply and is cut off, the disappearance of the electromagnetic force of the end face of electromagnet (17), under the effect of the pulling force of spring (10), castellated shaft guide frame (8) drives castellated shaft (7) to being the rotations of spring (10) one sides, the skate (18) that feasible and castellated shaft (7) connects firmly together disengages with resistance (19), like this, in the time of can preventing that automobile is in operation the top ripple, automobile leaf spring fluctuates up and down and drives skate (18) and move around on resistance (19), increases the wearing and tearing of skate (18) between resistance (19).At this moment, the effect of spring (10) is the position that limits castellated shaft guide frame (8), and the end face of electromagnet (17) and the distance between the wedge type iron block (15) are remained in certain scope.
In order to prevent that muddy water from entering into the carload measuring device, influence survey precision, be that there is a groove shell (2) port inboard, the interior sheet rubber (12) of groove that antifouling board (14) is contained in resistance (19) lower end one side is contained in the opposite side groove, and the sheet rubber middle part has a kerf.Castellated shaft (7) passes the opening at sheet rubber middle part and free movable.The available common current table transformation of the way of automobile load test indicator (28) according to different automobile types, designs different ranges and overload warning area.
