Abstract
The utility model relates to the technical field of vehicle equipment frames, in particular to a rear suspension lifting lug for assembly of a plate spring suspension. The side walls of a main plate protrude to form a pair of supporting lugs, and the bottom of the main plate protrudes to form a bottom plate which is bent towards a frame. The main plate is hexagonal, and the four corners of the upper portion of the main plate are provided with fixing holes respectively. Each supporting lug is of an inverted U-shaped structure and comprises two symmetrical side plates and a top plate connecting the two side plates. Each side plate is of a triangular structure, a fixing hole is formed in the downward top corner of each side plate, and the portions, located on the two sides of each main reinforcing rib, of each top plate are symmetrically provided with auxiliary installing holes. The two top corners of the bottom plate are provided with auxiliary fixing holes. The main plate further comprises a main reinforcing rib covering the top plates and a connecting layer stretching to cover the side plate close to the outside. Due to the fact that a bearing force transfer mode is improved, internal stress of the frame changes, lateral shear stress is converted to forward pressure stress, and therefore bearing capacity and reliability are improved.
Description
Technical field
The utility model relates to vehicle arrangement vehicle frame technical field, relates in particular to a kind of rear suspension hanger that assembles Leaf Spring Suspension.
Background technology
At present, the suspension shackle of goods carrying vehicle is by Plate Welding moulding, then welds or is riveted on vehicle frame.Be exactly specifically, steel spring is by being connected with the hanger arranging on vehicle frame, thereby load that steel spring accepts is realized and the transmission of vehicle frame by hanger.
In prior art, hanger 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, hanger poor reliability of the prior art.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of rear suspension hanger is provided, solves the easily stressed defect that deforms and lost efficacy of hanger of the prior art, realize the reliability that improves rear suspension hanger; 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, and the bottom of mainboard stretches out a base plate to vehicle frame bending;
Described mainboard is hexagon, on four angles of top, offers 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, on top board, be positioned at main reinforced rib bilateral symmetry be provided with auxiliary mounting hole;
Two drift angle places of described base plate are provided with auxiliary fixed orifice;
Described mainboard also comprises the main reinforced rib that is coated on top board top, and extends to the articulamentum being coated on side plate in the outer part.
The bottom of described top board also has additional T-shaped reinforcement structural slab.
Described auxiliary mounting hole is opened in to be strengthened on structural slab.
Described base plate is isosceles trapezoid.
Between described base plate and inner side side plate, auxiliary reinforced rib is set.
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.

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 5 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, and the bottom of mainboard 1 stretches out a base plate 3 to vehicle frame bending;
Described mainboard 1 is hexagon, on four angles of top, offers respectively fixed orifice 11; The utility model is connected on vehicle frame by fixed orifice 11 and auxiliary fixed orifice 31, is connected firmly, and is difficult for getting loose.
Described support ear 2 is П type structure, comprise symmetrical two blocks of side plates 21 and the top board 22 that is connected two blocks of side plates 21, side plate 21 is triangular structure, and drift angle place is down provided with mounting hole 21, on top board 22, be positioned at main reinforced rib 11 bilateral symmetry be provided with auxiliary mounting hole 221; Steel spring is installed on respectively among fixed orifice 21 and auxiliary mounting hole 221 by bearing pin and screw.
Two drift angle places of described base plate 3 are provided with auxiliary fixed orifice 31;
Described mainboard 1 also comprises the main reinforced rib 12 that is coated on top board 22 tops, and extends to the articulamentum 13 being coated on side plate 21 in the outer part.
The bottom of described top board 22 also has additional T-shaped reinforcement structural slab 22.
Described auxiliary mounting hole 221 is opened in to be strengthened on structural slab 22.
Described base plate 3 is isosceles trapezoid.
Auxiliary reinforced rib 23 is set between described base plate 3 and inner side 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, thus make that hanger is stressed to change, 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 of hanger changes as mentioned above, and lateral shear stress conversion is forward compression effort, thereby has improved the reliability of hanger.
As mentioned above, the internal stress of vehicle frame changes, and lateral shear stress conversion is forward compression effort, thereby has improved the reliability of hanger.
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.
