Abstract
The utility model discloses a double axle series balance suspension device for lorries, which includes a spring block, a bracket, a connection shaft, a balance shaft, a bottom plate and a rod, etc. The spring block is installed on the balance shaft mounted on the bracket. The bottom plate and the bracket body are connected with multiple rods, and brackets are connected with a rotating shaft. The balance shaft adopts '2+1' independent type, i.e. two balance shafts are mounted on two brackets connected with a connection shaft respectively. Shaft diameter of the balance shaft is phi125mm, and the spring block 1 is of four-U bolt type. The utility model enables the balance shaft to generate no stress, increases tensile and tearing strength of shaft and fatigue resistance of the bracket, reduces the likeliness of cracks and substantially enhances stability of the spring block; bolts are not easy to break and the bottom plate is of good integrity and solidity to prevent occurrence of breaking or cracking.
Description
Technical field
The utility model relates to a kind of configuration of automotive suspension device, and more particularly, the utility model relates to a kind of goods carrying vehicle doube bridge series balance draft hitch.
Background technology
At present, goods carrying vehicle balance suspension axle is " Ω " type integral type, and balance shaft diameter of axle Φ 100mm easily produces stress concentration, fatiguability fracture, diameter of axle tension less than normal, folding undercapacity.Do not have the rib of adding with support frame body between each bolt hole of base plate, a little less than the fatigue resistance, easily produce brisement.Spring block is two " U " type bolt, and the steadiness of leaf spring is poor, and bolt is easily broken.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, solves balance shaft and easily produces stress concentration, fatiguability fracture, diameter of axle tension less than normal, folding undercapacity; Overcome support base plate weak strength, easily produce brisement; The steadiness of leaf spring is poor, and bolt is easily broken, the difficult problem that stress equalization is bad.
For achieving the above object, the utility model is taked following design plan:
The utility model balance shaft is " 2+1 " type stand alone type, and promptly two balance shafts are installed in respectively on two supports, and two supports adopt an adapter shaft to connect balance shaft diameter of axle Φ 125mm;
Establish rib with support frame body between each bolt hole of base plate;
Spring block adopts four " U " type screw bolt-type;
The utility model has the advantages that: the unstressed concentrated generation of (1) balance shaft, diameter of axle tension folding intensity increases.(2) the support fatigue resistance strengthens greatly, is difficult for cracking.(3) strengthened the steadiness of leaf spring greatly, bolt is not easily broken.(4) the bracket bottom slab integral good, lead admittedly, can not produce the brisement phenomenon.
Description of drawings
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is birds-eye vieies of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1, the utility model will be further described for accompanying drawing 2.
In the drawings, this goods carrying vehicle doube bridge series balance draft hitch is to be made of spring block 1, support 2, adapter shaft 3, balance shaft 4, base plate 5, rib 6 or the like.
Described spring block 1 is installed on the balance shaft 4, and balance shaft 4 is installed on the support 2, and base plate 5 is connected with a plurality of ribs 6 with support frame body, is connected with adapter shaft 3 between support and the support.
Described balance shaft 4 adopts " 2+1 " type stand alone type, and promptly two balance shafts are installed in respectively on two supports, and two supports adopt an adapter shaft to connect, balance shaft diameter of axle Φ 125mm, and spring block 1 adopts four " U " type screw bolt-type.
