Abstract
The utility model changes the screw spring structure of the traditional two prop booster, which provides a twisting rod type two prop booster of novel structure. The basic component of the booster is a steel rod. The assisted power of the two prop is realized through a twisting rod matching with a fixed block and a loaded connecting shaft sleeve. The twisting rod type two prop booster has the advantages of simple structure, easy use, saving raw material and man hours, which can be widely used on the traction frames of the motor cars and the tractor-trailers.
Description
The utility model has related to the attached device that helps of trailer, a kind of specifically work-saving device that is applicable to that automobile, trac. independent trailer drawbar frame use.Existing automobile, tractor trailer drawbar frame work-saving device are two garden post coil springs, the pulling force that relies on spring with the pull-up of drawbar frame power-assisted so that laborsaving loading and unloading trailer of saving trouble.But existing spring assist apparatus structure more complicated (forming) by nine other parts such as spring, pipe link, adjust bar, accent knot mother, adapter plates, it is time-consuming that manufacturing processing is got up, and cost is higher, and is transferring knot bar junction to rupture easily.
The utility model proposes a kind of simple, thereby practical torsion bar type drawbar frame work-saving device make work-saving device from processing and manufacturing to installing and using the labor and material saving that becomes, simple, and can guarantee that failure-free uses.
The utility model is that an application force with the shearing force opposite sign but equal magnitude that is produced when utilizing a steel pole to be subjected to external torque within elastic limit is unconsummated.
Specific tasks of the present utility model are by a torsion bar, and a fixed block and a loading connecting bushing are realized.Fixed block has a mounting hole above being fixed on the turntable mounting of auto trailer or tractor trailer, loading connecting bushing is fixed on the drawbar frame, torsion bar is the main body of this work-saving device, be steel pole always, the one end is bent into the elbows that become 90 degree with the body of rod, claims fixedly elbow, the other end is bent into one 90 degree elbows round about, but with fixedly elbow is not in same plane, but upwards angled, title loads elbow.Two elbows of torsion bar couple together with fixed block and loading coupling bush respectively, promptly constitute a complete torsion bar work-saving device.Fixedly elbow with work-saving device during installation inserts in the mounting hole of fixed block, then drawbar frame upwards is raised on the angle position at loading elbow place of steel pole, to load in the elbow insertion loading connecting bushing and get final product, at this moment the torsion bar work-saving device just is added to an application force that makes progress on the drawbar frame, makes drawbar frame remain on (as level attitude) on the certain position.
Work-saving device realizes that by length that changes steel pole and the angle that loads elbow steel pole length is short more, the big more then application force of angle of bend is also big more to the big I of drawbar frame application force, otherwise application force is more little.
The utility model is easy to realize because simple in structure, thereby the processing and manufacturing saving of work and time that gets up, and greatly reduces the cost of product, saved raw MAT'L.
Specific embodiment of the utility model is provided by following accompanying drawing.
Fig. 1 is the erection plan of torsion bar work-saving device on the trailer towing frame
Fig. 2 is the structural representation of torsion bar work-saving device torsion bar
Fig. 3 is the constructional drawing of torsion bar work-saving device fixed block
Fig. 4 loads the front view (analysing and observe) of connecting bushing for the torsion bar work-saving device
Below in conjunction with accompanying drawing this utility model is described further.
As scheme this work-saving device by torsion bar (2), fixed block (1) and loading connecting bushing (3) are formed, the body of rod of torsion bar (2) is made with the 60Si2Mn spring steel of ∮ 16mm, it loads elbow (6) and is upturned and becomes 40～70 to spend angles with fixing elbow (4), one location pin-and-hole (5) is arranged on the fixedly elbow of torsion bar, in order to strengthen the rigidity of torsion bar, avoid stress concentration, can with the two ends of torsion bar slightly honest thick after bending forming again.Fixed block (1) is a square bloom, is welded on the turntable mounting of auto trailer, and the installation slotted hole (7) of a ∮ 18mm is arranged above.Load connecting bushing (3) and be one and have the steel bushing of stepped hole, be welded on the back rest of drawbar frame, with the diameter of the equipped mutually aperture (8) of axostylus axostyle is 18mm, during installation, the fixedly elbow (4) of torsion bar is inserted in the mounting hole of fixed block (1), pin with pin, the loading elbow (6) of torsion bar inserts and loads in the connecting bushing (3), should guarantee to make the axis of the torsion bar body of rod to overlap with the suspension axis of drawbar frame in order to guarantee that torsion bar only bears when the moment of torsion that is brought by drawbar frame is installed.
Easy to use, durable in use, respond well according to the torsion bar work-saving device that present embodiment is manufactured through this work-saving device of probationary certificate on two 5 tons of trailers.
Claims (3)
1, a kind of drawbar frame work-saving device, it is characterized in that this work-saving device is to realize power-assisted by a torsion bar (2), work-saving device includes torsion bar (2), fixed block (1), with loading connecting bushing (3) three parts, one end of torsion bar is fixed on by fixed block on the turntable mounting of auto trailer, and the other end connects together by loading connecting bushing and drawbar frame.
2, work-saving device as claimed in claim 1 is characterized in that said torsion bar is steel pole always, its two ends be bent into both direction on the contrary, in a plane and two elbows become 90 degree with the steel pole body.
3, work-saving device as claimed in claim 1 is characterized in that said fixed block is one to have the square iron block of mounting hole, is fixed on the Automobile turntable frame, and said loading connecting bushing is the steel axle sleeve of a band stepped hole, is fixed on the drawbar frame.
