Description
Technical field
The utility model relates to vehicle arrangement vehicle frame technical field, relates in particular to a kind of vehicle frame that assembles Leaf Spring Suspension and hangs pin.
Background technology
At present, it is by Plate Welding moulding that the suspension of goods carrying vehicle hangs pin, then welds or is riveted on vehicle frame.Be exactly specifically, steel spring is by being connected with the pin that hangs arranging on vehicle frame, thereby load that steel spring accepts is realized and the transmission of vehicle frame by hanging pin.
In prior art, hanging pin is plurality of steel plates welding fabrication, by welding or being riveted on vehicle frame.Weldment has following deficiency:
High temperature when 1 welding has destroyed localised crystal's structure, makes strength of material variation;
After 2 welding, produce stress and concentrate, in the place of stressed variation poor reliability;
3 homogeneity of product are poor with respect to Casting Parts, are unfavorable for mass production.
And steel spring this as elasticity original paper, in work, often in vibrational state, the suffered stress of the each parts of assembly is just in range of alternating stresses herein.For these reasons, the pin poor reliability of hanging of the prior art.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of
vehicle frame hangs pin, solve the easily stressed defect that deforms and lost efficacy of pin of hanging of the prior art, realize and improving
vehicle frame hangs pinreliability; Solve the part conformability of batch manufacturing, accomplish scale production.
The utility model comprises mainboard and support ear, and the sidewall of described mainboard stretches out a width support ear; Described mainboard top is triangle, and three summits offer respectively fixed orifice; Described support ear is П type structure, comprises symmetrical two blocks of side plates and the top board that is connected two blocks of side plates, and side plate is triangular structure, and drift angle place is down provided with mounting hole; The rear wall of described mainboard is also provided with the reinforced rib of M type, is also provided with the rectangle set pin of an insertion vehicle frame between reinforced rib and mounting hole.M type reinforced rib intensity is high, hangs pin good stability, not yielding.
The both sides of described top board are also provided with auxiliary mounting hole.Steel spring is installed between mounting hole and auxiliary mounting hole by bearing pin and bolt, has improved stability and tightness.
Described mainboard also comprises the bar shaped enhancement Layer that is coated on both sides, top board top.Improve the intensity of top board.
Described auxiliary mounting hole is arranged on bar shaped enhancement Layer.Improve the intensity of top board.
Described bar shaped enhancement Layer also comprises the assistant reinforcement muscle extending on the side plate of outside.Therefore improved the intensity of outside side plate.
Because the utility model has improved bearing capacity transfer mode, thereby the internal stress of vehicle frame is changed, lateral shear stress conversion is forward compression effort, thereby has improved load-carrying capacity and reliability.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing 1 to 2 in the following describes is embodiment of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The utility model comprises mainboard 1 and support ear 2, and the sidewall of described mainboard 1 stretches out a width support ear 2; Described mainboard 1 top is triangle, and three summits offer respectively fixed orifice 11; Described support ear 2 is П type structure, comprises symmetrical two blocks of side plates 21 and the top board 22 that is connected two blocks of side plates 21, and side plate 21 is triangular structure, and drift angle place is down provided with mounting hole 21; The rear wall of described mainboard 1 is also provided with the reinforced rib 11 of M type, is also provided with the rectangle set pin 13 of an insertion vehicle frame between reinforced rib 11 and mounting hole 21.M type reinforced rib 11 intensity are high, hang pin good stability, not yielding.
The both sides of described top board 22 are also provided with auxiliary mounting hole 221.Steel spring is installed between mounting hole 21 and auxiliary mounting hole 221 by bearing pin and bolt, has improved stability and tightness.
Described mainboard 1 also comprises the bar shaped enhancement Layer 14 that is coated on top board 22 both sides, top.Improve the intensity of top board 22.
Described auxiliary mounting hole 221 is arranged on bar shaped enhancement Layer 14.Improve the intensity of top board 22.
Described bar shaped enhancement Layer 14 also comprises the assistant reinforcement muscle 15 extending on the side plate 21 of outside.Therefore improved the intensity of outside side plate 21.
Structure as above and mounting means, suspension is stressed to be changed, and suffered automobile leaf spring is converted into thrust and the tangential force perpendicular to frame web plane perpendicular to ground bearing pressure.
Structure as above and mounting means, thereby make to hang, pin is stressed changes, and shearing force major part is converted into the positive pressure of pointing to frame web.Due to the shearing force of rivet is converted into positive pressure, thereby steel spring bearing capacity is converted into the friction force that riveted joint predetermincd tension produces, has improved the reliability of whole mechanism.
The stressed of vehicle frame changes as mentioned above, and tangential force is changed to friction force by riveted joint precompressed.
The internal stress that hangs as mentioned above pin changes, and lateral shear stress conversion is forward compression effort, thereby has improved the reliability that hangs pin.
As mentioned above, the internal stress of vehicle frame changes, and lateral shear stress conversion is forward compression effort, thereby has improved the reliability that hangs pin.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong to the protection domain of technical solutions of the utility model.
