Abstract
The utility model relates to a light truck plate spring. The light truck plate spring comprises a main spring, a subsidiary spring and a bolt, wherein the main spring and the subsidiary spring are connected together through the bolt, the main spring is composed of two long reeds superimposed up and down, two ends of an upper long reed of the main spring are curved into lifting lugs, a lower subsidiary spring is arranged on the lower portion of the main spring, the lower subsidiary spring is arc-shaped, two end heads of the lower subsidiary spring bend downward, reed hoops are arranged at two ends of the lower subsidiary spring and connect the lower subsidiary spring with the main spring, an upper subsidiary spring is arranged on the upper portion of the main spring, two spacers which are superimposed up and down are arranged between the upper subsidiary spring and the main spring, the upper subsidiary spring is composed of three reeds superimposed up and down, and lengths of the three reeds decrease progressively from top to bottom. The light truck plate spring is reasonable in design, simple in structure, novel, east to manufacture, low in cost, and reliable in performance, enables a truck to be consistent in smoothness under unloaded, full-loaded and overloaded conditions, and improves service life of the truck.
Description
Technical field
The utility model relates to the automobile shock technical field, specifically a kind of light card leaf springs of car.
Background technology
At present, leaf spring is widely used in the shock absorption device of automobile, the primary member of leaf spring is plate spring sheet, leaf spring clip and bolt, the length of plate spring sheet is stepped successively decreases, the annexes such as bolt and leaf spring clip are assembled into plate spring assembly, the plate spring sheet length of the superiors is maximum, bends out hanger at its two ends, is used for leaf springs of car is installed on the car body below.When leaf springs of car is stressed, utilize the elastic force of leaf spring self, reach the effect of compensator or trimmer pressure.The rigidity leaf springs such as most of employings of existing leaf springs of car, because its load-deflection curve is linear, unloaded, fully loaded when automobile, when overloading, the leaf spring natural frequency of vibration differs greatly, easily produce friction in the process of moving and between the leaf spring reed, reduced life of plate spring, affect car load service life.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of rational in infrastructure, function admirable, and service-strong gently blocks leaf springs of car.
The technical scheme that the utility model adopts is: a kind of light card leaf springs of car, comprise main spring, auxiliary spring, bolt, bolt is with main spring, auxiliary spring links together, it is characterized in that main spring is comprised of two long reeds of up and down stack, the upper long reed bending two ends of main spring becomes hanger, be provided with lower auxiliary spring in main spring bottom, the curved two ends of lower auxiliary spring reed is bent downwardly, be provided with the reed clip at the two ends of lower auxiliary spring, lower auxiliary spring is connected with main spring, is provided with auxiliary spring on main spring top, be provided with up and down two pads of stack between upper auxiliary spring and the main spring, upper auxiliary spring is comprised of three reeds of up and down stack, and three length of spring leaf are successively decreased from top to bottom.
Because the curved two ends of lower auxiliary spring reed is bent downwardly, when unloaded, only main spring bears unloaded load, and lower auxiliary spring and upper auxiliary spring are in no load state; Work as at full load, main spring bears fully loaded load with lower auxiliary spring; When overload, main spring bears overload load with upper auxiliary spring.The utility model is reasonable in design, and simple in structure, novel, easy to manufacture, cost is low, dependable performance, make automobile empty, full, the overload ride comfort is consistent, the service life of having improved automobile.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark among the figure: 1, hanger, 2, main spring, 3, lower auxiliary spring, 4, upper auxiliary spring, 5, bolt, 6, clip.
The specific embodiment
By shown in Figure 1, a kind of light card leaf springs of car, comprise main spring 2, auxiliary spring 3,4, bolt 5, bolt 5 is with main spring 2, auxiliary spring 3,4 link together, main spring 2 is comprised of two long reeds of up and down stack, the upper long reed bending two ends of main spring 2 becomes hanger 1, be provided with lower auxiliary spring 3 in main spring 2 bottoms, the curved two ends of lower auxiliary spring 3 reeds is bent downwardly, and is provided with reed clip 6 at the two ends of lower auxiliary spring, and lower auxiliary spring 3 is connected with main spring 2, be provided with auxiliary spring 4 on main spring 2 tops, be provided with up and down two pads of stack between upper auxiliary spring 4 and the main spring 2, upper auxiliary spring 4 is comprised of three reeds of up and down stack, and three length of spring leaf are successively decreased from top to bottom.
The utility model adopts 60Si2Mn to make, cost is low, the upper long reed bending two ends of main spring becomes hanger, be installed in the car body bottom, because the curved two ends of lower auxiliary spring are bent downwardly, lower auxiliary spring is not contacted with main spring tailpiece end, and the acute angle that can effectively reduce auxiliary spring sheet end scratches main spring tailpiece, improves the main spring tailpiece life-span.When unloaded, main spring bears unloaded load, and lower auxiliary spring and upper auxiliary spring are in no load state, and at full load master spring bears fully loaded load with lower auxiliary spring, and master's spring bears overload load with upper auxiliary spring during overload.Compare with the uniform thickness leaf spring, it is too high to solve when unloaded frequency, and at full load is on the low side, and the leaf spring phenomenon of difficulty of travelling during overload improves leaf spring service life, make automobile empty, full, the overload ride comfort is consistent.
