By adding the reinforcing plate, an original U-shaped cross section in a lapping region is changed into a closed quadrate cross section, a welding seam no longer bears alternating stress directly, the stress level in the lapping region can be reduced remarkably, and the twisting motion of the torsion beam can not be caused in the region. Therefore, product reliability is enabled to be improved.
Description
Technical field
The utility model relates to a kind of back bridge construction of vehicle, particularly relates to bridge construction after a kind of torsion beam.
Background technology
Back torsion beam device on the automobile is one of requisite parts of automobile.In the prior art, back bridge construction comprises the torsion beam and the rear axle following arm that is connected to its two ends in U type cross section; The rear axle following arm configuration has various ways, and it is the most general that wherein back axle drg mounting bracket employing steel plate strikes out rear axle following arm configuration application on present manned vehicle of welding after certain profile cooperation tube bending moulding or the steel plate punching press.By steel pipe clod wash, extruding or steel plate punching press welding, with the rear axle following arm according to the moulding of design-calculated shape in order to cooperate back axle drg mounting bracket.
Notification number is that the Chinese utility model patent of CN201132479Y discloses torsion beam device behind a kind of automobile, it comprise the back torsion beam and on rear stabilizer bar, this torsion beam end, back is connecting brake disc, described torsion beam afterwards connects brake disc by contiguous block.
Publication number is that the Chinese invention patent application of CN1348881A discloses a kind of rear suspension, in the rear suspension of vehicle, curve place K/UP in each right side and the zone line of left trailing arm between front end column part and rear end part is so trailing arm is the L type substantially.Each end with basic torsion beam for U type cross section is connected the district that is inclined upwardly of each trailing arm, and this trailing arm tilts to curve from rear end part.
Torsion beam type back axle has multiple version, wherein adopts towing arm and torsion beam directly to weld as the mode of agent structure comparatively general.Because torsion beam type back axle is in twisting states at work for a long time, torsion beam is born reverse stress, the weld seam product failure that causes easy to crack for a long time with the weld seam that pulls arm.In order to improve the structural strength in parts overlap joint zone, the structure more complicated of product and be subjected to the restriction of existing technological level.
Summary of the invention
The utility model main purpose is in order to solve under the twisting states of torsion beam type back axle in long-term work, and the weld seam of torsion beam and towing arm bears reverse stress for a long time and produces the problem that weld seam is easy to crack, cause product failure.A kind of torsion beam additional strengthening is provided, satisfies the reliability of products requirement.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of torsion beam additional strengthening comprises the torsion beam in U type cross section and is welded on the towing arm at described torsion beam two ends; Also be provided with a brace panel in described torsion beam and towing arm weld, a horizontal ends of described brace panel is welded to connect on described towing arm, and two ends are welded to connect the both sides at described torsion beam U type opening respectively up and down.By increasing brace panel, make the regional original U type of overlap joint cross section become the osed top square-section, weld seam no longer directly bears reverse stress, has significantly reduced the stress level in overlap joint zone, the twisting motion of torsion beam is not produced in this zone, thereby reliability of products is got a promotion.
As a kind of optimal technical scheme of the utility model, described brace panel roughly is the zigzag bending, is provided with first section, second section and the 3rd section, is provided with a U type notch in described the 3rd section end.By original structure, in order to reduce torsion beam and the regional stress level of towing arm overlap joint, all need on the towing arm, design a plane, make towing arm and torsion beam possess enough contact surfaces.Adopt this structure, can use a simple structure, satisfy the requirement of the stress level that reduces the overlap joint zone.
As a kind of optimal technical scheme of the utility model, described U type notch is provided with the lip limit, and described lip spring folding direction is towards described torsion beam.As a kind of further optimal technical scheme of the utility model, the width of described U type notch is about 1/3rd of described the 3rd section end width.Brace panel design by this structure can improve the distribution of stress in this overlap joint zone preferably, satisfies the stress level requirement in overlap joint zone better.
As a kind of optimal technical scheme of the utility model, also be provided with a rectangular aperture in the centre of described brace panel.By in the middle of brace panel, an opening being set, when the stress level that can make the brace panel structure satisfy the overlap joint zone requires, alleviate the overall weight of torsion beam type back axle, satisfy the requirement of vehicle weight-saving.
By the technical solution of the utility model, can produce following beneficial effect:
1, simplifies towing arm and torsion beam product design thinking;
2, use comparatively easy forming technology, can satisfy the requirement of product structure intensity;
3, compare with existing torsion beam type back axle structure: this brace panel structure can significantly be improved this regional distribution of stress situation, improves reliability of products.
