Description
Technical Field
The invention relates to the technical field of automobile leaf springs, in particular to a leaf spring.
Background
The suspension is one of the main components of modern automobiles, can elastically connect a frame with an axle, and has the main tasks of transmitting all forces and moments acting between the frame and wheels, relieving impact load transmitted to the frame due to uneven road surfaces, attenuating vibration of a bearing system caused by the impact load and ensuring normal running of the automobile.
The suspension is generally composed of an elastic element, a guide mechanism and a damping device. The elastic element mainly comprises: leaf springs, coil springs, rubber springs, air springs, hydro-pneumatic springs, and the like. In the long-term development process, the steel plate spring has the characteristics of simple structure, lower manufacturing cost, small occupied space, convenience in maintenance and the like, and becomes an elastic element which is widely adopted in various countries in the world.
The steel plate spring is an elastic element which is most widely applied in the automobile suspension, the stress condition of the steel plate spring can directly influence the automobile suspension, the steel plate springs in the current market have poor bearing capacity and short fatigue life, after the service life of the steel plate spring is prolonged, the plates can mutually slide and rub to generate noise, and the relative friction between the steel plates can also cause the spring to deform to cause unsmooth running.
Disclosure of Invention
The invention aims to provide a multifunctional fire fighting device to solve the problems in the background technology.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
a steel plate spring comprises a steel plate and a main bolt for connecting the steel plate; the steel plates comprise a first main steel plate, a second main steel plate, a third main steel plate, a fourth main steel plate, a fifth main steel plate, a sixth main steel plate, a seventh main steel plate, an eighth main steel plate and an auxiliary main steel plate which are sequentially stacked; the two ends of the first main body steel plate are provided with flat rolling lugs, the two ends of the second main body steel plate are provided with flat wrapping lugs, and the two ends of the fifth main body steel plate and the seventh main body steel plate are provided with frame-shaped clamping pieces; frame-shaped clamps are arranged at two ends of the auxiliary main body steel plate; the distance between the main bolt and the center of the two flat rolling lugs is equal, and the main bolt is fixed through a main nut.
Furthermore, a friction plate is arranged between the spring pieces.
Furthermore, a protection pad is arranged between the eighth main body steel plate and the auxiliary main body steel plate.
Furthermore, a bolt is arranged in a flat rolling lug hole of the flat rolling lug.
Furthermore, the frame-shaped hoop is connected with a corresponding nut through a screw rod.
Further, the bottom of the frame-shaped clamping piece is riveted with a fifth main steel plate, a seventh main steel plate and a ninth main steel plate through rivets.
The invention has the beneficial effects that: according to the steel plate spring provided by the invention, when the automobile suspension is impacted by external force, the first main steel plate is broken, the second main steel plate provides protection, the bearing capacity of the steel plate spring is enhanced, the fatigue life and the economic benefit are improved, the limited space is utilized to the maximum extent, and the smoothness of an automobile is improved. Be equipped with the friction disc between main part steel sheet and the main part steel sheet, be equipped with the protection pad on the supplementary main part steel sheet, effectively reduce each reed center department operating stress, improve leaf spring life, noise pollution abatement.

FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view of the leaf spring a-a shown in fig. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, a leaf spring includes a leaf plate and a main bolt connecting the leaf plate; the steel plates comprise a first main steel plate 3, a second main steel plate 4, a third main steel plate 5, a fourth main steel plate 6, a fifth main steel plate 7, a sixth main steel plate 8, a seventh main steel plate 9, an eighth main steel plate 10 and an auxiliary main steel plate 11 which are sequentially overlapped; the both ends of first main part steel sheet 3 are equipped with flat book ear 1, and second main part steel sheet both ends are equipped with flat package ear 2, fifth main part steel sheet 7 and seventh main part steel sheet 9 both ends all are equipped with frame shape card 14, 11 both ends of auxiliary main part steel sheet all are equipped with frame shape clamp 12, main screw 16 equals apart from two flat book ear central distance, and is fixed through main nut 17.
Further, a friction plate 141 is arranged between the main body steel plate and the main body steel plate.
Further, a protection pad 13 is arranged between the eighth main body steel plate 8 and the auxiliary main body steel plate 11.
Further, a bolt 15 is arranged in a flat rolling lug hole of the flat rolling lug.
Further, the frame-shaped clamp is connected by a screw 19 and a corresponding nut 18.
Further, the bottom of the frame-shaped card 14 is riveted with the fifth main body steel plate 7, the seventh main body steel plate 9 and the auxiliary main body steel plate 11 by rivets 142.
When the steel plate spring deforms under the action of load, friction is generated between the plates due to relative sliding, and the damping of the vibration of the vehicle frame can be promoted.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
