Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment one
One kind as shown in Fig. 1,2,3,4,5 is based on the prolongable rear torsion beam suspension frame structure of platform, including crossbeam 100 and symmetrical
Two trailing arm assemblies 200 at 100 both ends of crossbeam are welded in, wherein trailing arm assembly 200 primarily serves the effect of carrying longitudinal force, horizontal
Beam 100 primarily serves the effect of carrying twisting resistance, resists inclination, steering etc. in vehicle driving.Crossbeam 100 includes middle section 110
With the adjusting section 120 for being integrally connected to 110 two sides of middle section, adjust 120 section of section is in closed fillet trapezoid shape, by this
Shape can have the ability of effectively supporting top car body weight, by closed crossbeam 100, be effectively reduced rear suspension weight
Under the premise of, bigger adjustment and load bandwidth are provided, meet the needs of vehicle performance and carrying.Its end is total to fit in trailing arm
At 200 surfaces and the connecting pin 130 that is welded and fixed with it.
In the present embodiment, 130 two sides of connecting pin be equipped be cut by laser to be formed from its edge to Inner arc indent
Recessed portion 131.I.e. in preliminary production, the end for adjusting section 120 is neat shape, after the blank output of crossbeam 100, root
It is cut by laser and to be formed according to the wheel spacing for the vehicle being currently adapted to and the structure of trailing arm assembly 200, i.e., in the retrotorsion
In beam suspension frame structure, middle section 110 is designed to mechanical property as the part of main load and meets all vehicle need in the platform
The fixed universal architecture of the size shape asked adjusts section 120 and is designed as in blank output as certain length such as without adjusting
30-60cm, and it is cut to suitable length in the subsequent cutting for adapting to vehicle, so that each vehicle in a platform
Independent design and checking computations in type without progress suspension respectively, can pass through torsion beam under the premise of not changing main body of cross-beam structure
To realize, different wheelspan extensions, reduction design the complexity and work of production procedure to the cutting characteristic of beam-end between platform vehicle type
It measures, improves production efficiency.Connecting pin 130 includes the upper interconnecting piece 132 for being located at 131 top of recessed portion formed after cutting, and
Lower interconnecting piece 133 positioned at the lower section of recessed portion 131, the upper interconnecting piece 132 in the present embodiment is rounded triangle shape, lower interconnecting piece
133 be fillet trapezoid shape, then recessed portion 131 is cooperated to form down big up small nozzle type structure, is that trailing arm assembly 200 connects
When state that be in nozzle type be fitted into the corresponding part part of trailing arm assembly 200, to have good company after the completion of welding
Intensity and supportive are connect, overall structure is also more simple.
In the present embodiment, the inverted V-shaped that 110 section of middle section is enclosed in closing is good so as to have by inverted V-shaped shape
The structure of bearing vehicle body, parameter designing are to be adapted in platform the use demand of whole vehicles, while downwardly open knot
Structure to be suspended in the operating condition (reversing between the wheel as caused by the more complicated road conditions such as unilateral bridge, intersecting axle) in face of torsion
When, it carries out opening with can be convenient shrinks simultaneously elastic torsion deformation, and then fatigue, bending equal loss can be reduced, improve and use
Service life.
In the present embodiment, the both ends of the inverted V-shaped in 110 section of middle section are in inside protrusion, and then are formed for its opening
The reinforcement structure for locating both ends avoids its thickness is excessively thin from leading to problems such as to tear in the work of carrying torsion.
In the present embodiment, the inverted V-shaped opening angle in 110 section of middle section is acute angle, to have lesser volume and have
Good bearing capacity.
In the present embodiment, middle section 110 and adjust between section 120 in gradually big by one from middle section 110 to 120 area of section of section is adjusted
Body connection can be made because adjusting section 120 is different from the cross-sectional structure in middle section 110 by gradually big continuously coupled mode
The two intersection transitions smooth, mechanical structure is good, so that will not become the weak spot in monocoque structure at this, improves peace
Full performance.
In the present embodiment, crossbeam 100 is that seamless steel pipe or other raw material are preliminary by the progress cold stamping of corresponding mold
Molding is followed by the production method of heat-treating profiled process the final shaping, and relatively existing common hydro-forming mode has more smart
The production procedure of letter, and can greatly increase torsion beam bearing capacity.
In the present embodiment, trailing arm assembly 200 includes trailing arm frame 210, bracket 220, bushing bracket 230, spring holder 240 and subtracts
Shake device bracket 250, and bushing bracket 230 is embedded at the front end of trailing arm frame 210, and bracket 220 and damper bracket 250 are fixed in trailing arm
The rear end of frame 210, the connecting pin 130 of crossbeam 100 are fixed in 210 middle part of trailing arm frame, and trailing arm frame 210 is trailing arm assembly 200
Main body, spring holder 240 is for installing the spring of vertical direction bearing vehicle body in suspension frame structure and transmitting spring force, damper bracket
250, for supporting mounting dampers lower end, transmit the active force of damper.Bushing bracket 230 and bracket 200 are used for and vehicle body connects
It connects.These components can with trailing arm frame 210 carry out pre-welding composition trailing arm assembly 210 after as an integral module with crossbeam
100 connections, further increase modularization for the adaptability of single platform multi-vehicle-type.
In the present embodiment, 240 two sides of spring holder are separately connected 210 rear end of trailing arm frame and connecting pin 130 and trailing arm frame 210 connects
Place is met, the spring of spring holder 210 needs the weight of bearing vehicle body, belongs to the biggish structure of service load, distinguishes by its two sides
Connection 210 rear end of trailing arm frame and connecting pin 130 and 210 junction of trailing arm frame cry to form subtriangular connection bearing structure,
So as to effectively improve its bearing capacity and job stability in the case where not increasing reinforcer.
