Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
Assembling structural representation of the present utility model as shown in Figure 1, including the assembly 8 that cuts section bar after front overhang starting section beam assembly 1, longitudinal beam connected assembly and the front overhang set gradually from front to back.Described front overhang starting section beam assembly 1, the lifting force seat assembly including front overhang starting section beam, being arranged on beam stage casing, front overhang starting section and be arranged on the lower thrust bearing assembly bottom the beam of front overhang starting section.Described longitudinal beam connected assembly includes symmetrically arranged left longitudinal beam connected assembly 2 and right longitudinal beam connected assembly 3；The left side of described left longitudinal beam connected assembly 2 is provided with left air-bag support assembly 6；The right side of described right longitudinal beam connected assembly 3 is provided with right air-bag support assembly 7；Connect between upper end, stage casing and the upper end, stage casing of described right longitudinal beam connected assembly 3 of described left longitudinal beam connected assembly 2 and have middle part buttress brace assembly 4；Connect between lower end, stage casing and the lower end, stage casing of described right longitudinal beam connected assembly 3 of described left longitudinal beam connected assembly 2 and have lateral thrust seat support assembly 5.Assuming there are two different passenger vehicles, the underframe height of a passenger vehicle is 1.2m, the underframe height of another passenger vehicle is 1.5m.These two passenger vehicles of hypothesis are equipped with identical forward mounting (propons is connected on front suspended beam) by forward mounting, it means that forward mounting installation on front suspended beam is identical.But owing to the height of two underframe of coach 9 is different, a 1.2m, a 1.5m, it is therefore desirable to two front suspended beams of design.This block that forward mounting is installed by this utility model is independent makes a modular front suspended beam structure, although so the height of underframe of coach is different, but this block of front suspended beam structure described in the utility model (being also the most complicated place) is constant, and change is upper height.
Traditional passenger car airbag support is arranged above special structure to connect air-bag support, although but this structural strength is high also the heaviest, the utilization rate of material is the lowest, and the height space that attachment structure needs are higher is set on top, many passenger vehicles are relatively low and need to design air bag attachment structure and cause inside passenger vehicle needs prominent certain altitude in car at front overhang due to underframe, the most not convenient the most unsightly.And the attachment structure of the attachment structure of shock absorber support and air-bag support is independently arranged, manifest the heaviness of traditional structure further.Under passenger vehicle normal operating condition, the power upwards of the air bag that left and right air-bag support assembly is respectively subjected to, owing to left and right air-bag support assembly described in the utility model is cantilever design, this can produce inside torsional moment, due to left and right torsional moment the most internally, have in structure middle part buttress brace assembly its have enough intensity to undertake the torsional moment from both sides.Torsional moment from about macroscopic analysis has the trend cancelled out each other, passenger vehicle front overhang starting section described in the utility model beam assembly mainly to undertake active force upwards simultaneously, even if long-term operation, structure also will not deform.
As shown in Figure 2, described front overhang starting section beam includes the first entablature 101 and the first sill 102 from up to down set gradually, the first left column 103 and the first right column 104 being successively set on from left to right between the first entablature 101 and the first sill 102, the first left diagonal brace 105 and the first right diagonal brace 106 being symmetricly set between the first entablature 101 and the first sill 102, diagonal brace 108 strengthened by the first reinforcement diagonal brace 107 and second between the first left column 103 and the first right column 104 arranged in a crossed manner, be arranged between the first left diagonal brace 105 and the first sill 102 first left be connected column 109 and be arranged between the first right diagonal brace 106 and the first sill 102 first right be connected column 110.
Described first left diagonal brace 105, its upper end is connected on the junction on the left of described first entablature 101 and described first left column 103, and its lower end is connected to the left end of described first sill 102；Described first right diagonal brace 106, its upper end is connected on the junction of described first entablature 101 and described first right column 104, and its lower end is connected to the right-hand member of described first sill 102；Described first strengthens diagonal brace 107, and its upper end is connected on the junction on the right side of described first entablature 101 and described first left column 103, and its lower end is connected on the junction on the left of described first sill 102 and described first right column 104；Described second strengthens diagonal brace 108, and its upper end is connected on the junction on the left of described first entablature 101 and described first right column 104, and its lower end is connected on the junction on the right side of described first sill 102 and described first left column 103.
