Abstract
The utility model discloses a novel asymmetrically-parabolic leaf spring assembly. The novel asymmetrically-parabolic leaf spring assembly comprises a plurality of stacked leaf springs, spacers are arranged between every two adjacent leaf springs and on the outsides of the top leaf spring and the bottom leaf spring, each leaf spring and the spacers are fastened by fasteners, and two ends of each leaf spring are fixedly connected through leaf spring clamps. The two ends of the leaf springs are fixedly connected by bolts and nuts of the leaf spring clamps, and open composite bushes are pressed into spring eyes at two ends of the main leaf spring to be fixedly connected with the outer sides of the leaf spring clamps. The novel asymmetrically-parabolic leaf spring assembly only comprising four leaf springs is lighter as compared with a trapezoidal leaf spring assembly so as to totally meet the automotive lightweight design principle. By the aid of the open composite bushes for connection, original rigid pin shaft connection among the leaf springs, a leaf spring support and lifting lugs is changed to elastic connection. When an automobile is started or braked, rigid shock among the leaf springs and the support is weakened by the aid of the open composite bushes for connection, comfortableness of the whole automobile is improved, and the service lives of the leaf springs and the connecting support are effectively prolonged.
Description
Technical field
The utility model relates to a kind of novel asymmetric parabola steel plate spring assembly, belongs to mechanical field.
Background technique
Leaf spring is the main load-carrying unit of heavy-duty car, and mostly traditional leaf spring is the trapezoidal leaf spring of multi-disc of each sheet uniform thickness, length symmetry, and trapezoidal Multi-Leaf Springs rigidity is bigger, and weight is heavier.Trapezoidal Multi-Leaf Springs relies on bearing pin to be connected with flat spring bracket and hanger more, need be lubricated bearing pin simultaneously.This Placement is more loaded down with trivial details, and needs periodic maintenance, brings a lot of inconvenience to the user.
The model utility content
To above-mentioned deficiency, the utility model provides a kind of novel asymmetric parabola steel plate spring assembly.
The utility model is realized through following organization plan:
A kind of novel asymmetric parabola steel plate spring assembly, it comprises a plurality of range upon range of sheet springs, and the said adjacent sheet spring and the superiors and undermost spring outside are equipped with pad, and each sheet spring and pad are fastening through fastening piece; The two ends of sheet spring are fixedly connected with the leaf spring clamp.
Said leaf spring clamp is fixedly connected each sheet spring two through leaf spring clamp bolt and nut, the opening composite bush is pressed into main leaf spring two ends grasswort, is fixedly connected with the outside of leaf spring clamp.
Be provided with rubber in the said opening composite bush.
A kind of novel asymmetric parabola steel plate spring assembly mainly is made up of a plurality of springs, center nut, centre bolt, pad, leaf spring clamp, clamp bolt and nut and opening composite bush; Wherein, Pad is fixedly connected with centre bolt through being connected center nut with the main leaf spring; Be provided with spacers between main leaf spring and second spring and be connected, be provided with spacers between second spring and the 3rd spring and be connected, be provided with spacers between the 3rd spring and the 4th spring and be connected; Described all sheet springs and pad all have center hole at the middle part, and are fixedly connected with centre bolt through center nut; Above-mentioned all sheet spring two are provided with the leaf spring clamp, and the leaf spring clamp is fixedly connected sheet spring two through leaf spring clamp bolt and nut, and the opening composite bush is pressed into main leaf spring two ends grasswort, is fixedly connected with the outside of leaf spring clamp.
Working principle: main leaf spring, second spring, the 3rd spring, the 4th spring are installed by mode from top to bottom successively, and between every pad is installed all, use centre bolt, center nut that four leaf springs are fastening again.Two ends clamp with leaf spring clamp, clamp screw bolt and nut, avoid the plate spring sheet dislocation.At last the opening composite bush is pressed into main leaf spring two ends grasswort, and guarantees oblique following 45 ° of composite bush opening, guarantee to meet the frock requirement.
The beneficial effect of the utility model: the utility model sheet spring assembly has only four, and trapezoidal relatively steel plate spring assembly weight is lighter, satisfies the light-weight design principle of automobile fully.Leaf spring adopts the opening composite bush to connect, and makes that becoming elasticity by original rigidity bearing pin connection between leaf spring and flat spring bracket and the hanger connects.When automobile is starting and during braking, the Placement of opening composite bush has reduced the rigid impulse between leaf spring and the support, has improved the travelling comfort of car load, effectively raise leaf spring simultaneously and connect working life of support.The distortion of rubber can be satisfied reversing of leaf spring and deflection in the composite bush, without any need for lubricated and maintenance, has made things convenient for the user greatly.Have rational in infrastructure, characteristics such as system is accurate, long service life, product are stable, good in economic efficiency, safe and reliable to operation.
