Abstract
The utility model discloses a car rear longeron device, including a plurality of roots vertical fine strain of millet, a plurality of root stand and a plurality of roots bracing different in size different in size, fine strain of millet is intersected with the stand and is the cross setting from north to south, the bracing sets up is indulging played a supporting role between fine strain of millet and the stand, and part the one side of indulging fine strain of millet becomes the bent angle setting. This automobile rear is indulged the fine strain of millet device and except rational in infrastructure, indulged fine strain of millet in addition and adopt the bending machine to do processings of bending, and hot worked modes such as welding are adopted to the vertical fine strain of millet that has changed prior art, has also avoided taking place the vehicle bottom dish because of the welding is firm and the situation of splitting and perhaps ftractureing has appeared, has improved reliability of an item and security, simultaneously, has also improved the production efficiency of product.
Description
Technical field
The utility model relates to a kind of automobile rear longitudinal beam device.
Background technology
The rear longeron of existing car chassis is all adopt assembled welding in assembled process, and exactly square tube is cut angle welding, this welding manner belongs to hot working.But hot worked defect is exactly, due between square tube by the mode of welding, can there is weld seam, when fracture or cracking appear in car, being all substantially from the place of welding, is a very large potential safety hazard for car chassis.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of Stability Analysis of Structures and the automobile rear longitudinal beam device of safety.
In order to achieve the above object, the technical solution of the utility model is as follows: a kind of automobile rear longitudinal beam device, comprise some vertical fine strains of millet different in size, some columns different in size and some diagonal braces different in size, described vertical fine strain of millet and column decussate are arranged, and described diagonal brace is arranged between vertical fine strain of millet and column and plays a supporting role; And the side of the described vertical fine strain of millet of part becomes bent angle to arrange.
As preferably, the described vertical fine strain of millet part crossing with the left side second root post all does bending process; Vertical fine strain of millet has the six roots of sensation in this patent, column has five, and the four piece vertical fine strains of millet crossing with the left side second root post are all cooked bending process, and adopt pipe bending machine to carry out clod wash processing, pipe bending machine is adopted to process, substantially do not change the performance of material, and directly carry out bending and solve existing welding processing yet, decrease the potential safety hazard that car chassis indulges fine strain of millet device.
As preferably, described bent angle is θ, and θ is 164 °, and this angle can be arranged according to actual needs.
The beneficial effects of the utility model: this automobile rear indulges fine strain of millet device except rational in infrastructure, and vertical fine strain of millet adopts pipe bending machine to do bending process, the vertical fine strain of millet changing prior art adopts the hot worked modes such as welding, it also avoid the situation because welding chassis appearance fracture occurs built on the sand or ftractures, improve reliability and the safety of product, meanwhile, the production efficiency of product is also improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
Wherein: 1. vertical fine strain of millet, 2. column, 3. diagonal brace.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of automobile rear longitudinal beam device, comprise some vertical fine strains of millet 1 different in size, some columns 2 different in size and some diagonal braces 3 different in size, described vertical fine strain of millet 1 is arranged with column 2 decussate, and described diagonal brace 3 is arranged between vertical fine strain of millet 1 and column 2 and plays a supporting role; And the side of the described vertical fine strain of millet 1 of part becomes bent angle to arrange.
Described vertical fine strain of millet 1 part crossing with the left side second root post 2 all does bending process; Vertical fine strain of millet 1 has the six roots of sensation in this patent, column 2 has five, and four crossing with the left side second root post 2 vertical fine strains of millet 1 are all cooked bending process, and adopt pipe bending machine to carry out clod wash processing, pipe bending machine is adopted to process, substantially do not change the performance of material, and directly carry out bending and solve existing welding processing yet, decrease the potential safety hazard that car chassis indulges fine strain of millet device.
Described bent angle is θ, and θ is 164 °, and this angle can be arranged according to actual needs.
This automobile rear indulges fine strain of millet device except rational in infrastructure, and vertical fine strain of millet adopts pipe bending machine to do bending process, the vertical fine strain of millet changing prior art adopts the hot worked modes such as welding, it also avoid the situation because welding chassis appearance fracture occurs built on the sand or ftractures, improve reliability and the safety of product, meanwhile, the production efficiency of product is also improved.
