Abstract
The utility model relates to an enhanced balanced suspension, which comprises a cover board, a spring which is fixed on a spring base by a central bolt. The utility model is characterized in that: the cover is detachable, one side of each cover board is provided with two U-type bolts; a bearing hub spring base is lengthened relatively. The carrying capacity of the enhanced balanced suspension is improved; and the utility model can conquer the problem of the common balanced suspension that the leaf spring is ruptured from the center always; the maintenance for the central bolt is convenient, and the phenomenon of the hidden trouble from which the central bolt, the U-shaped bolt are broken can be avoided.
Description
Technical field: the utility model relates to a kind of heavier-duty balance suspension that is used for heavy goods vehicles.
Background technology: balance suspension is mainly used in two back axle heavy goods vehicles, and east wind company, First Auto Group balance suspension version are: the steel spring upper cover plate is an integral type, cover plate about every cover suspension, and each cover plate is fastening with two U-bolts.Integral type cover plate and steel spring area of contact are big, when fastening, limited by U-bolt to steel spring by U-bolt, and thrust is little, and the steel spring interlayer slip is big, easily center bolt is cut off.Center bolt fracture, in will directly causing, the back axle dislocation, hidden danger is very big, but because the integral type cover plate covers center bolt, the user can't in time find.
Summary of the invention: weak strength and easy problem that the utility model exists in order to solve existing balance suspension from the leaf spring center burst, a kind of heavier-duty balance suspension is proposed, comprise cover plate, be fastened on the leaf spring of spring block by center bolt, it is characterized in that: described cover plate is split type, each cover plate is one-sided two U-bolts, the corresponding lengthening of described bearing hub spring block.
The monolateral U-bolt of this heavier-duty balance suspension is four, the corresponding reinforcement of equalizer bearing hub, and suspension intensity obtains bigger raising, longer service life.The U-bolt span strengthens, and steel spring is increased by the moment of flexure scope, has disperseed stress, has overcome the problem of the normal steel spring that occurs of coventional type balance suspension from center burst; Adopt split type cover plate, solved integral type cover plate degree of freedom difference easy fracture phenomenon, and make things convenient for the maintenance of center bolt, avoid in time to find that hidden danger appears in the center bolt fracture; Because bearing hub spring block lengthening, dislocation has good restriction, avoided being back-outed existing center bolt and U-bolt phenomenon of rupture to the leaf spring interlayer.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: as shown in Figure 1, this heavier-duty balance suspension comprises cover plate 1,4, steel spring 5, and steel spring 5 is fastened on the spring block 6 by center bolt 3; Cover plate is split type, and the one-sided of cover plate 1,4 all is fastening by two U-bolts 2, adapts with it, is used for the bearing hub spring block 6 corresponding lengthenings of fastening U-bolt 2.
