Abstract
The utility model discloses a variable cross-section leaf spring for vehicles. The variable cross-section leaf spring comprises a leaf spring body, the leaf spring body is of a variable cross-section structure with a thick middle and two thin sides, a front rolled lug and a rear rolled lug are arranged at two ends of the leaf spring body respectively, a bush is arranged in the rolled lug at one end of the leaf spring body, a pad is arranged in the rear rolled lug, and a fixing plate is arranged in the middle of the leaf spring body. The variable cross-section leaf spring has the advantages that comfort and environment-friendly properties of the vehicles can be improved; and compared with traditional multi-plate identical cross-section leaf springs, on the premise that same functions and qualities are achieved, the single-plate variable cross-section leaf spring has the advantages that weight can be reduced by 30-40%, so that steel materials are greatly saved, weight of the whole vehicles are reduced, simultaneously, oil consumption is reduced, and environment protection is facilitated.
Description
Technical field
The utility model relates to automotive plate spring, especially relates to a kind of automobile-used variable-section steel sheet spring.
Background technique
The development level of automotive industry is to embody the important symbol of a national Industry Development Level and comprehensive manufacturing capacity.At present, the leaf spring that most of rear overhang rack is used all is made of the identical leaf spring of 1-4 sheet sectional dimension, many and weight is large with material, along with to automobile MPV(multipurpose passenger car particularly) improving constantly of requiring of the travelling comfort of vehicle and the feature of environmental protection, under the prerequisite that satisfies vehicle usage requirement and quality requirement, saving steel, reduction oil consumption just become the research direction of industry.
Summary of the invention
The purpose of this utility model is to provide a kind of can improve vehicle riding comfort and the feature of environmental protection, again can economical with materials, reduce the automobile-used variable-section steel sheet spring of oil consumption.
For achieving the above object, the utility model can be taked following technical proposals:
Automobile-used variable-section steel sheet spring described in the utility model comprises the leaf spring body, and described leaf spring body is the thin variable section structures in thick both sides, middle part, is respectively arranged with forward and backward grasswort at described leaf spring body two ends.
In the grasswort of described leaf spring body one end, be provided with lining, be provided with liner in the rear grasswort.
Middle part at described leaf spring body is provided with fixed plate.
The utility model has the advantage of travelling comfort and the feature of environmental protection that can improve vehicle.Under the prerequisite that reaches identical function and quality, with the section steel leaf spring, weight can alleviate 30-40% to the variable cross section single-leaf spring with respect to traditional multi-disc, has greatly saved steel, has reduced complete vehicle weight, also so that oil consumption descends, is more conducive to environmental protection simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, automobile-used variable-section steel sheet spring described in the utility model comprises the thin variable-section steel sheet spring body 1 in thick both sides, middle part, grasswort 2 and rear grasswort 3 before leaf spring body 1 two ends are respectively arranged with, in front grasswort 2, be provided with lining 4, be provided with liner 5 in the rear grasswort 3; Middle part at leaf spring body 1 is provided with fixed plate 6 by screw bolt and nut.
Monolithic variable-section steel sheet spring body 1(of the present utility model is called for short leaf spring 1) comparatively suitable MPV vehicle usefulness, the front grasswort 2 of monolithic changeable section plate spring 1 and lining 4 are bolted on the front fixed support place of car body, rear grasswort 3 and liner 5 are connected to car body rear suspension fixed support place by rear hanger assembly, after leaf spring 1 pressurized or tension, grasswort 3 can rotate by hanger behind the leaf spring, thereby regulate the length of leaf spring 1, reach the spring equilibrium of forces; Be connected to the wire harness that fixed plate 6 on the leaf spring 1 is used for the anti-skidding sensor of fixed vehicle by screw bolt and nut.
