Description
Technical Field
The utility model relates to a technical field of automobile design and manufacturing, more specifically says, the utility model relates to a leaf spring and FRP leaf spring composite construction.
Background
As shown in the following figure 1, in the prior art, in order to reduce the weight of a plate spring assembly, existing automobile manufacturers use GFRP or CFRP plate springs, aluminum alloy lugs or vulcanized rubber pads are required to be added at the end parts under the influence of the characteristics of the plate spring materials, and if the plate springs play a role in guiding, connection hidden troubles exist at the lug lugs, so that the plate springs are generally only used as springs in a transverse mode, such as Walvor new models XC90 and XC60, and the application range is limited to a certain extent. As shown in fig. 2, the multi-leaf spring is a widely used spring type, and adopts a gradually-changing stiffness leaf spring structure to improve the comfort under light load conditions, but because of the influence of materials and the number of leaves, the weight is larger, the unsprung weight is obviously increased, and the use of light vehicles is not facilitated.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned technical problem that exists among the prior art, the utility model aims to provide a leaf spring and FRP leaf spring composite construction.
The utility model discloses a leaf spring and FRP leaf spring composite construction, its characterized in that: the FRP plate spring is arranged between the upper pressing plate and the plate spring and is fixed through the central bolt and the central nut which penetrate through the plate spring, the FRP plate spring and the upper pressing plate, the FRP plate spring is arranged above the plate spring, two sides of the FRP plate spring bend upwards, and two sides of the plate spring bend downwards.
The upper pressure plate is a steel plate stamping part, and flanges clamped on two sides of the FRP plate spring are arranged on two sides of the upper pressure plate.
And two ends of the steel plate spring are provided with a lug or a mounting hole.
The steel plate spring and the FRP plate spring are fixed on a lower pressing plate on the installation shaft tube through two U-shaped bolts and nuts.
Compared with the prior art, the utility model discloses a leaf spring and FRP leaf spring composite construction have following beneficial effect:
The utility model discloses a composite construction has combined the advantage of leaf spring and FRP leaf spring, has enlarged the range of application, has reduced the FRP structure and has made and use the degree of difficulty.

Detailed Description
It is right to combine specific embodiment below the utility model discloses a leaf spring and FRP leaf spring composite construction do further explanation to help technical staff in this field to be right the utility model discloses a utility model design, technical scheme have more complete, accurate and deep understanding.
Example 1
As shown in fig. 3 to 4, the composite structure of the plate spring and the FRP plate spring of the present embodiment includes an upper plate 40, a center bolt nut 70, an FRP plate spring 10, and a plate spring 20, the FRP plate spring 10 being disposed between the upper plate 40 and the plate spring 20 and being fixed by the center bolt nut 70 passing through the plate spring 20, the FRP plate spring 10, and the upper plate 40, the FRP plate spring 10 being disposed above the plate spring 20. Both sides of the FRP plate spring 10 are bent upward, and both sides of the plate spring 20 are bent downward. The upper pressure plate 40 is a steel plate stamping part, and flanges punched on two sides of the upper pressure plate can be clamped on two sides of the FRP plate spring to prevent the FRP plate spring from rotating. The two ends of the leaf spring 20 are provided with a lug or a mounting hole (shown in the figure as a lug scheme) to complete connection with a suspension component or a frame, and the leaf spring can be used as a spring only or has a guide function. The leaf spring 20 and the FRP leaf spring 10 are fixed on the lower pressing plate 50 on the installation shaft tube 30 by two U-shaped bolts and nuts 60.
The composite construction of this embodiment combines together and constitutes a rigidity gradual change formula leaf spring assembly with FRP leaf spring traditional leaf spring promptly, and first leaf spring has around the eye structure can hold its guide effect concurrently, and the monolithic FRP leaf spring plays the vice spring effect, and the two advantage of full play remedies respectively not enough, and traditional multi-disc leaf spring can be showing weight reduction is compared to this assembly. The structure of the present embodiment can be used for all integral bridge dependent suspensions or a plurality of independent suspensions.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited to the above-mentioned embodiments, and various insubstantial modifications can be made without modification to the method concept and technical solution of the present invention, and the present invention is also within the scope of the present invention.
