Abstract
A kind of automobile chassis vehicle frame of lightweight stringer, middle cross beam (3) is weldingly fixed between left stringer (1) and right vertical beam (2), left stringer (1) and right vertical beam (2) are parallel to each other, left side beam (4) is arranged in the left side of left stringer (1), the right beam (5) is arranged on the right side of right vertical beam (2), left side beam (4), middle cross beam (3) and the right beam (5) are point-blank, the structural reinforcement member (6) is the U-shaped structure that Open Side Down, segmented welding is fixed on inside the U-shaped structure of left stringer (1) and right vertical beam (2), it is local to form hollow structure with left stringer (1) and right vertical beam (2).The present invention, effectively stringer and intermediate crossbeam and side bar effectively can be together in series by increasing structural reinforcement member in stringer, increase overall structural strength, and the place that other do not stress then reduces unnecessary sheet metal component, while guaranteeing chassis frame intensity, body lightening is realized.
Description
Technical field
The present invention relates to auto Body Technology fields, more particularly to a kind of chassis frame of lightweight automobile longitudinal girder.
Background technique
Automobile chassis vehicle frame generally uses bolt, nut cooperation to be fastenedly connected with car body, and specific structure is worn for fastening bolt
The mounting hole crossed on automobile chassis vehicle frame is fastenedly connected with the nut of welding on the car body.But often go out in assembling process
The nut misalignment of the mounting hole and welding of existing automobile chassis vehicle frame on the car body, the fastening bolt of belt washer are being screwed into nut
When there is the phenomenon that screw thread sliding teeth, cause assembly efficiency low.In addition, nut-welding is in the inside of car body, once there is screw thread
Sliding teeth, it is difficult to which directly replacement nut, rehabilitation cost are high.Therefore, it is necessary to the connection knots to existing automobile chassis vehicle frame and car body
Structure is improved.
Summary of the invention
According to the above problem, the purpose of the present invention is to provide a kind of automobile chassis vehicle frames of lightweight stringer, it is positioned
Accurately, connection is reliable, and assembly efficiency is high, easy to repair, produces low with rehabilitation cost.
The technical scheme is that be accomplished by the following way: a kind of automobile chassis vehicle frame of lightweight stringer, packet
The welded nut for including the mounting hole being located on frame assembly, being located on bodywork assembly, middle cross beam are weldingly fixed on left stringer and the right side
Between stringer, left stringer and right vertical beam are parallel to each other, and the left side of left stringer is arranged in left side beam, and right vertical beam is arranged in the right beam
Right side, point-blank, structural reinforcement member is arranged inside left stringer and right vertical beam for left side beam, middle cross beam and the right beam,
Be characterized in that: the structural reinforcement member is the U-shaped structure that Open Side Down, and segmented welding is fixed on the U of left stringer and right vertical beam
Type inside configuration, part form hollow structure with left stringer and right vertical beam.
The structural reinforcement member bending angle part is provided with anti-deformation abnormity arc opening.
The present invention, by stringer increase structural reinforcement member can effectively by stringer with centre crossbeam and side bar it is effective
It is together in series, increases overall structural strength, and the place that other do not stress then reduces unnecessary sheet metal component, is guaranteeing chassis
While frame strength, body lightening is realized.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is that Fig. 1 is top view.
Specific embodiment
Known by Fig. 1, Fig. 2, a kind of automobile chassis vehicle frame schematic diagram of lightweight stringer of the present invention, by left stringer 1, right vertical beam
2, middle cross beam 3, left side beam 4, the right beam 5, structural reinforcement member 6 form, middle cross beam 3 be weldingly fixed on left stringer 1 and right vertical beam 2 it
Between, left stringer 1 and right vertical beam 2 are parallel to each other, and the left side of left stringer 1 is arranged in left side beam 4, and right vertical beam 2 is arranged in the right beam 5
Right side, point-blank, structural reinforcement member 6 is arranged in left stringer 1 and right vertical beam 2 for left side beam 4, middle cross beam 3 and the right beam 5
Portion, the left stringer 1 and right vertical beam 2 are the U-shaped Sheet Metal Part of upward opening, and the end of U-shaped structure part, which has, to extend outwardly
Short planar structure, the structural reinforcement member 6 is the U-shaped structure that Open Side Down, and segmented welding is fixed on left stringer 1 and the right side is vertical
Inside the U-shaped structure of beam 2, part forms hollow structure, the structural reinforcement member 6U type knot with left stringer 1 and right vertical beam 2
The top and side of structure are provided with round lightening hole 6-1, and the 6 bending angle part of structural reinforcement member is provided with anti-deformation abnormity circle
Nock 6-2.
