Stress point avoids the weak part of the first leaf spring pin to end-transfer, and the scheme compared with prior art is compared, and reduces the first plate
The failure risk of spring pin, meanwhile, the dispersible internal stress of shackle plate of curved profile reduces stress concentration, so as to improve hanger
Plate resistance to deformation or the ability of destruction, its mechanical property are higher, improve the reliability of the connecting assembly.
Front suspension stopping means provided by the utility model includes the limitting casing of L-shaped steel plate, and it passes through punch forming, limit
Position frame is bolted on the lateral surface of vehicle frame.Limited block is the tabular base for including the convex portion of semicylinder He being attached thereto
Portion, convex portion and base portion are molded using polyurethane.Then the base portion of limited block is placed on the leaf spring of main spring group, passed through
Limited block and lead spring assembly are fixed on front axle by U-bolts.So when in vehicle travel process wheel run into barrier
When, when wheel hop is to certain altitude, limited block hits with limitting casing realizes that front suspension system is spacing.
The beneficial effects of the utility model：Multiple leaf springs are included by the main spring of design, auxiliary spring includes multiple steel plates
Spring, so can enable lead spring assembly bear bigger load；Pass through the stopper slot designed on auxiliary spring, main spring and auxiliary spring
And be not directly contacted with, therefore the abrasion of main spring and auxiliary spring can be not only greatly reduced, and can greatly reduce because of main spring
Collision with auxiliary spring and the noise produced；By the hanger of design, evade the weak part of leaf spring pin, reduce the mistake of leaf spring pin
Risk is imitated, security is improved；The automotive suspension of the utility model tool has good, easy to maintenance shock-absorbing capacity, service life length, made an uproar
The advantages of sound is small and safe.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
