Description

Car body of a bridge bracing or strutting arrangement

Technical field

The utility model belongs to technical field of automobile components, relates in particular to a kind of car body of a bridge bracing or strutting arrangement.

Background technology

The crossbeam of the current car body of a bridge, trailing arm adopt the iron plate rolled-up stock more.Because iron plate rolled-up stock thinner thickness, its space hold area is big, and anti-seismic performance is relatively poor, and is yielding, and processed complex.

The utility model content

Problem to be solved in the utility model just provides that a kind of space hold area is little, and anti-seismic performance is strong, and is not yielding, easily the car body of a bridge bracing or strutting arrangement of processing.

For addressing the above problem, the technical solution adopted in the utility model is: comprise crossbeam, trailing arm, described crossbeam, trailing arm are tubulose.

Its additional technical feature is: described crossbeam, trailing arm are flat type tubulose; Have through hole on described tubular cross bearer, the trailing arm; The end face of described tubular cross bearer, trailing arm is provided with angle.

Car body of a bridge bracing or strutting arrangement provided by the utility model compared with prior art, crossbeam, trailing arm are tubulose, substitute thin plate with the high-quality solid drawn pipe, adopt advanced hydraulic pipe bending equipment to make tube bending, numerical control control angle of bend, the position degree is accurate, and processing technology is simple, and the tubular cross bearer after the moulding, trailing arm anti-seismic performance are strong, endurance, simplify airframe structure, not yielding, the space hold area is little.Crossbeam, trailing arm are flat type tubulose, and its stability is strong.And having through hole on the tubular cross bearer, trailing arm, the end face of tubular cross bearer, trailing arm is provided with angle, and is easy for installation.

Description of drawings

Fig. 1 is the structural representation of the crossbeam of the utility model car body of a bridge bracing or strutting arrangement;

Fig. 2 is the structural representation of the trailing arm of car body of a bridge bracing or strutting arrangement.

The specific embodiment

Be described in further details below in conjunction with the concrete structure and the use principle of accompanying drawing the utility model car body of a bridge bracing or strutting arrangement.

As shown in Figure 1, the crossbeam 1 of the utility model car body of a bridge bracing or strutting arrangement is a tubulose, and crossbeam 1 has through hole 2.As shown in Figure 2, trailing arm 3 is a tubulose, and trailing arm 3 has through hole 2, and the end face of trailing arm 3 is provided with angle 4.

The crossbeam 1 of car body of a bridge bracing or strutting arrangement provided by the utility model, trailing arm 3 are tubulose, substitute thin plate with the high-quality solid drawn pipe, adopt advanced hydraulic pipe bending equipment to make tube bending, numerical control control angle of bend, the position degree is accurate, processing technology is simple, tubular cross bearer 1, trailing arm 3 anti-seismic performances after the moulding are strong, and endurance is simplified airframe structure, not yielding, the space hold area is little.And having through hole 2 on the tubular cross bearer 1, trailing arm 3, end face is provided with angle 4, and is easy for installation.

When the crossbeam 1 of car body of a bridge bracing or strutting arrangement provided by the utility model, trailing arm 3 made, with raw MAT'L blanking through checking after, bend pipe, saw end face, flatten, drill through hole, saw end face angle, boring, polishing, flaw detection after check put in storage.Entire product is smooth smooth, defectives such as flawless, fold, and no sharp edge, burr, product 100% magnetic particle inspection detects, and demagnetization is handled.

Claims

1. car body of a bridge bracing or strutting arrangement comprises crossbeam, trailing arm, it is characterized in that: described crossbeam, trailing arm are tubulose.
