Abstract
The utility model discloses a semi-trailing transport vehicle with a reversely placed plate spring, and relates to the technical field of production of various types of semi-trailing transport vehicles with reversely placed plate springs. The semi-trailing transport vehicle comprises a vehicle frame assembly, suspension assemblies and a plurality of wheel axle assemblies, wherein the lower end of a longitudinal beam of the vehicle frame assembly is fixedly connected with the suspension assembly; a U-shaped bolt is hung on the axle of each axle assembly; each U-shaped bolt is provided with the reversely placed plate spring; the front end and the rear end of the reversely placed plate spring are disposed on the corresponding suspension assemblies respectively; and a hard block is fixedly connected between the right upside of the axle of the axle assembly and the lower end of the longitudinal beam of the vehicle frame assembly. The hard block can well limit re-deformation of the plate spring, so that the plate spring and the U-shaped bolt do not need to bear greater gravity, in this way the plate spring and the U-shaped bolt are protected effectively, and the purpose of safe driving is achieved.
Description
Technical field
The utility model relates to the conveying semi-trailer production technical field that all kinds of leaf springs are inverted.
Background technology
Continuous development along with the communications and transportation industry; The user is that the low more of more is good to the carrying surface requirement of superimposed trailer; So with superimposed trailer and adorn diaxon and adorn three leaf spring and be inverted by just putting instead of routine; Its defective also displays day by day: reversible deformation appears in leaf spring, and " U " type bolt easy fracture etc. have brought hidden danger to traffic safety.
Summary of the invention
The utility model purpose is to design a kind of leaf spring of avoiding and the leaf spring semitrailer that is inverted that phenomenons such as reversible deformation, " U " type bolt easy fracture take place occurs.
The utility model comprises the leaf spring semitrailer that is inverted; Comprise frame assembly, suspension assembly and some axle aggregates; The captive joint suspension assembly in the longeron lower end of frame assembly is hung " U " type bolt on the vehicle bridge of each axle aggregate, the leaf spring that is inverted is set on each " U " type bolt; The be inverted forward and backward two ends of leaf spring are shelved on respectively on the corresponding suspension assembly, it is characterized in that captiveing joint hard block directly over the vehicle bridge of axle aggregate with between the longeron lower end of frame assembly.
When the superimposed trailer lade, corresponding distortion takes place in the leaf spring that is inverted, and " U " type bolt load also increases gradually; After increasing to a certain degree; The lower plane of this hard block engages with the last plane of vehicle bridge, and this device will be had an effect, and unnecessary bearing capacity directly is passed on the vehicle bridge.Hard block can limit the deformation again of leaf spring well, and this moment, leaf spring and " U " type bolt no longer bore more gravity, thereby had protected leaf spring and " U " type bolt effectively, reached the purpose of safe driving.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The utility model comprises the axle aggregate 2 of frame assembly 1 and horizontally set; The captive joint suspension assembly 3 in the longeron lower end of frame assembly 1; On the vehicle bridge of each axle aggregate 2, hang " U " type bolt 4, the leaf spring 5 that is inverted is set on " U " type bolt 4, the forward and backward two ends of the leaf spring 5 that is inverted are shelved on respectively on the corresponding suspension assembly 3.
The longeron lower wing plate 1-1 welding hard block 6 of the frame assembly 1 directly over the vehicle bridge of axle aggregate 2.
