Abstract
The utility model discloses a back steel plate spring for an environmental sanitation vehicle, and the back steel plate spring comprises main steel plate springs and auxiliary steel plate springs. A liner plate is arranged between the main steel plate springs and the auxiliary steel plate springs; further, the middle parts of the main steel plate springs and the auxiliary steel plate springs are connected through a center bolt; two ends of a first main steel plate spring are bent into spring eyes; the spring eyes are internally provided with a lining respectively; two ends of a second main steel plate spring are bent into spring eyes covering the outsides of the spring eyes of the first main steel plate spring; two sides of each of the first main steel plate spring, the second main steel plate spring and a third main steel plate spring are connected through a spring clip; and two sides of each of a first auxiliary steel plate spring, a second auxiliary steel plate spring and a third auxiliary steel plate spring are connected through a clamping band. The back steel plate spring has the advantages of simple, firm and reliable structure, flexibility in arrangement, and strong bearing capacity.
Description
Technical field
The utility model relates to rear overhang rack and uses rear spring, especially relates to a kind of environmental sanitation car rear spring.
Background technique
At present, China's cargo vehicle suspension uses leaf spring as elastic element mostly.The elastic beam that its leaf spring all is made up of some alloy spring sheets, the automobile of big bearing capacity uses the combined type rear spring more.But two ends grasswort root fracture in use appears in a lot of rear springs, and there are phenomenons such as noise rear spring and vehicle frame joint.In addition because the ratio of rigidity unreasonable distribution of major-minor leaf spring causes the stressed yield limit that surpasses material of partial spring sheet when heavy duty.
Summary of the invention
The utility model purpose is to provide a kind of good rigidly, environmental sanitation car rear spring that bearing capacity is strong.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described environmental sanitation car of the utility model rear spring comprises main steel plate spring and auxiliary spring, be provided with backing plate between said main steel plate spring and the auxiliary spring, and the middle part is connected through centre bolt; Said first main steel plate both ends of the spring curves grasswort, is respectively arranged with lining in the said grasswort; Curve the grasswort outside that grasswort is coated on said first main steel plate spring at second main steel plate both ends of the spring; Said first, second and third sheet main steel plate spring both sides are connected through spring clip, and first, second and third sheet auxiliary spring both sides are connected through clip.
The utility model advantage is simple in structure, solid and reliable, flexible arrangement, and bearing capacity is strong.The good rigidly of spring, the grasswort place is easy-rupturing not, and leaf spring and vehicle frame joint are difficult for producing frictional noise.When bearing load, the main steel plate spring is bearing load at first, and after load reached predetermined design objective, auxiliary spring also began stressed simultaneously.Main steel plate spring and auxiliary spring support automobile load simultaneously, effectively improve the bearing capacity of automobile hind axle.
