Abstract
The utility model relates to a diagonal brace U-shaped bolt balanced suspension system, which comprises a cover plate, a U-shaped bolt, a steel plate spring and a balanced suspension; the steel plate spring is arranged on the balanced suspension; the integrated cover plate is arranged in the center of the steel plate spring; the utility model is characterized by 4 U-shaped bolts; every two U-shaped bolts are made into one group; the two groups of the U-shaped bolts takes on a symmetrical form, so that an integrated type cover plate and a steel plate spring are tightened on the spring support of the balanced suspension through a diagonal brace mode. The utility model has the advantages that, at the same time of not changing the stiffness of prior suspension systems, the balanced suspension system can improve driving smoothness, increase compression force of the U-shaped bolt, compress the plate spring and prevent run-out of the plate spring plate, and resolve the problems of bottom crack of the steel plate spring central bolt and fissure of the steel plate spring; the system is characterized by simple structure, light weight, high strength and perfect smoothness etc.
Description
Technical field:
The utility model relates to a kind of cable-stayed type U-bolt equalizing suspension system, belongs to the rear linkage of two back axle highways of large-tonnage and the dual-purpose bogie in cross-country road.
Background technology:
Equalizing suspension system is applicable to two back axle heavy goods vehicles, the equalizing suspension system of present domestic employing has two kinds: one, every cover suspension system adopts 2 U-bolt Straight pull structures: cover plate is installed on the steel spring, every side suspension system is installed 2 U-bolts, and U-bolt is vertically installed.The thrust of this kind structure U-bolt is little, between each sheet of leaf spring slippage big, the center bolt of steel spring is easily cut off, and influences leaf spring and uses; Two, every cover suspension system adopts 4 U-bolt Straight pull structures: cover plate is installed on the steel spring, every side suspension system is installed 4 U-bolts, U-bolt is vertically installed, this kind structure is the heavier-duty of first kind of structure, the thrust of U-bolt is improved, fracture of spring centre bolt root and steel spring middle part breakage problem have been solved, but because the spring perch of balance suspension lengthening, or else the action length that changes the prerequisite lower steel plate spring of wheelbase reduces, rigidity of plate spring increases, and influences the ride comfort of car load.
Summary of the invention:
The purpose of this utility model is: in rigidity that does not change original suspension system and leaf spring work area, improve whole bearing capability, solve fracture of spring centre bolt root and steel spring breakage problem, a kind of cable-stayed type U-bolt equalizing suspension system is provided.
The purpose of this utility model is realized by following mode:
The utility model comprises cover plate, U-bolt, steel spring, balance suspension, steel spring places on the balance suspension, the integral type cover plate places the center on the steel spring, it is characterized in that: adopt 4 U-bolts, per two U-bolts are one group, be symmetric form with integral type cover plate, steel spring between two groups of U-bolts, be fastened on by the mode of tiltedly drawing on the spring perch of balance suspension.
Installation angle between every group of U-bolt and vertical direction is 11 °～15 °.
The utility model effect:
In the rigidity that does not change original suspension system, improved travelling comfort, improved the thrust of U-bolt, both compress leaf spring, prevented the plate spring sheet play again, solved fracture of spring centre bolt root and steel spring breakage problem, this system has simple in structure, in light weight, intensity height, characteristics such as ride comfort is good.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model comprises cover plate 1, U-bolt 2, steel spring 3, balance suspension 4, and steel spring 3 places on the balance suspension 4, and integral type cover plate 1 places the center on the steel spring 3.Adopt 4 U-bolts 2, per two U-bolts are one group, are symmetric form between two groups of U-bolts with integral type cover plate 1, steel spring 3, are fastened on by the mode of tiltedly drawing on the spring perch of balance suspension 4.Every group of U-bolt setting angle determines that according to the structure of equalizing suspension system and the parameter of steel spring in design process, we determine that the installation angle between every group of U-bolt and vertical direction is 11 °～15 °.
Car load in the process of moving, slippage trend before and after steel spring can produce, because U-bolt fastening makes between the spring perch of steel spring and balance suspension and each sheet of steel spring and produce friction drag, the conicity force of while cable-stayed type U-bolt has suppressed the slippage of steel spring.
Claims (2)
1. cable-stayed type U-bolt equalizing suspension system, comprise cover plate, U-bolt, steel spring, balance suspension, steel spring places on the balance suspension, the integral type cover plate places the center on the steel spring, it is characterized in that: adopt 4 U-bolts, per two U-bolts are one group, are symmetric form with integral type cover plate, steel spring between two groups of U-bolts, are fastened on by the mode of tiltedly drawing on the spring perch of balance suspension.
2. cable-stayed type U-bolt equalizing suspension system according to claim 1 is characterized in that: the installation angle between every group of U-bolt and vertical direction is 11 °～15 °.
