Description
Technical Field
The invention relates to the field of frame structures, in particular to a spring seat installation reinforcing structure of an automobile damping spring.
Background
The automobile can produce vibrations in the road surface operation process, and the speed of automobile is faster, and the road conditions is more complicated, and this kind of vibrations is big more, and on the contrary, this kind of vibrations are also great to the load of automobile body spring holder. In general, a design engineer may set a damping spring on the vehicle to absorb such vibrations, thereby ensuring that the vehicle can operate stably.
One end of the damping spring is connected with the wheel, the other end of the damping spring is connected with the vehicle body longitudinal beam, in the prior art, large dislocation is formed between the vehicle body longitudinal beam and the wheel in the vehicle width direction, and the spring seat of the damping spring arranged vertically and the vehicle body longitudinal beam are dislocated in the vehicle width direction, so that the spring seat mounting plate is required to be connected with the spring seat and the vehicle body longitudinal beam and can generate certain bending moment. However, for new energy vehicles, particularly hybrid vehicles, the vehicle body weight is heavy, so that impact force generated on the spring seat is large when the vehicle jolts, and bending moment generated on the spring seat mounting plate is also large, so that the safety problem that the spring seat mounting plate is deformed or even damaged to cause traffic accidents easily occurs in the driving process of the vehicle.
Disclosure of Invention
The invention aims to provide a spring seat installation reinforcing structure capable of bearing the impact load of a damping spring of a heavy vehicle during bumping.
In order to achieve the purpose, the scheme of the invention is as follows: the utility model provides a spring holder installation additional strengthening, includes the spring seat board that links to each other with the longeron lower surface of flat putting, the lower facial features of spring seat board is used for installing the spring holder, and the partial plate body suspension of spring seat board is connected with the side reinforcing plate between the lateral wall of the suspension part of spring seat board and longeron.
Can effectively transmit the load of spring holder for the longeron side through the side reinforcing plate in the above-mentioned scheme, avoid at the car in-process of traveling, the spring seat board bears great load, and the side reinforcing plate has also promoted the bending resistance of spring seat board simultaneously.

Detailed Description
The utility model provides a spring seat installation additional strengthening, includes the spring seat board 20 that the flat and continuous with longeron 10 lower surface that puts, the lower facial features of spring seat board 20 is used for installing the spring seat, and the partial plate body suspension of spring seat board 20 is connected with side reinforcing plate 30 between the lateral wall 11 of the suspension part of spring seat board 20 and longeron 10. In the above scheme, even if the stress point of the spring seat deviates from the position of the longitudinal beam 10, the load of the spring seat can be transmitted to the side face of the longitudinal beam through the side reinforcing plate, so that the situation that the spring seat plate bears large load in the driving process of an automobile is avoided, and meanwhile, the bending resistance of the spring seat plate is also improved through the side reinforcing plate.
The side reinforcing plate 30 is L-shaped, a transverse plate 31 of the side reinforcing plate 30 is connected with the upper surface of the spring seat plate 20, and a vertical plate 32 of the side reinforcing plate 30 is connected with the side wall 11 of the longitudinal beam 10. Since the plate surface of the spring seat plate 20 is perpendicular to the wall surface of the side wall 11 of the longitudinal beam 10, the L-shaped side reinforcing plate 30 is more easily welded with the spring seat plate 20 and the side wall 11 of the longitudinal beam 10.
And reinforcing ribs are arranged between the transverse plate 31 and the vertical plate 32. The arrangement of the reinforcing ribs further improves the structural strength of the transverse plate 31 and the vertical plate 32, and simultaneously improves the bending resistance of the spring seat plate 20 connected with the transverse plate 31.
The spring seat mounting reinforcement structure according to claim 3, characterized in that: the reinforcing rib is an arc plate 33 formed by stamping partial plate bodies of the transverse plate 31 and the vertical plate 32, and a curvature axis core of the arc plate 33 is obliquely arranged and is positioned below the arc plate 33. So that the arc-shaped plate 33 can effectively cancel the impact load on the spring seat.
The area of the arc-shaped plate 33 accounts for 20-50% of the total area of the side reinforcing plate 30. The larger area of the arcuate plate 33 is more resistant to impact loads.
The connecting parts of the transverse plate 31, the vertical plate 32 and the arc-shaped plate 33 are in round corner transition. Therefore, deformation cracking of a large break angle area caused by stress concentration after impact load is avoided.
The plate edge of the suspension part of the spring seat plate 20 is provided with a flanging 21. The provision of the turned-over edge 21 increases the bending resistance of the suspended part of the spring seat plate 20 itself.
The suspension part of the spring seat plate 20 is a trapezoidal plate with an upper suspension end. The area of the suspension end is reduced to avoid interfering other parts.
The connecting part of the spring seat plate 20 and the longitudinal beam 10 is provided with a positioning convex rib 22, and a positioning table 12 with the shape matched with the positioning convex rib 22 is arranged on the longitudinal beam 10 corresponding to the positioning convex rib 22. The accurate installation of spring seat board 20 on longeron 10 of being convenient for carries on spacingly to spring seat board 20's horizontal position simultaneously, reduces the horizontal load of welding position, avoids the solder joint fracture.
