Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Examples
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a novel front longitudinal additional strengthening, includes front longitudinal 3, and front longitudinal 3's inside is equipped with stiffening beam 11, is equipped with mounting hole 6 behind mounting hole 6 and the second behind the second on the stiffening beam 11 respectively, and the internally mounted of stiffening beam 11 has two bolt sleeves 10, and two bolt sleeves 10 are corresponding with mounting hole 6 behind the second and the mounting hole 8 behind the second respectively.
As shown in fig. 1: first mounting and positioning holes 4 are symmetrically formed in two sides of the front longitudinal beam 3; with the above arrangement, it is easy to fit the second fitting positioning hole 9, and then the reinforcement beam 11 is fitted inside the front side member 3.
As shown in fig. 1 and 2: second mounting positioning holes 9 are symmetrically formed in two sides of the reinforcing beam 11, and the positions of the second mounting positioning holes 9 and the first mounting positioning holes 4 correspond to each other; through the arrangement, the position of the reinforcing beam 11 is convenient to position and install.
As shown in fig. 1: a first front mounting hole 5 and a first rear mounting hole 2 are respectively formed in the front longitudinal beam 3; through the arrangement, the engine right suspension 1 can be conveniently installed.
