Front partition plate lower mounting plate and cross beam assembly

Abstract

The invention discloses a front partition plate lower mounting plate and cross beam assembly, which comprises a front partition plate lower mounting plate and a cross beam. The front partition plate lower mounting plate comprises a partition plate horizontal wall, a first vertical wall and a second vertical wall; the first vertical wall and the second vertical wall horizontally extend upwards to be fixed to the front side and the rear side of the partition plate horizontal wall correspondingly; and the cross beam is horizontally fixed to the front side of the upper surface of the partition plate horizontal wall, and a front hoarding is fixed to the rear end of the second vertical wall. According to the front partition plate lower mounting plate and cross beam assembly, the overall rigidityof a front partition plate lower mounting part is effectively improved, the overall torsional rigidity of an engine cabin is increased, thus the overall torsional rigidity of an engine in the Y direction is increased to from 15415 Nm to 16503 Nm, and the torsional rigidity is increased by about 7%.

Description

technical field [0001] The invention relates to a crossbeam assembly of a lower mounting plate of a front bulkhead, in particular to a crossbeam assembly of a lower mounting plate of a front bulkhead which improves the overall rigidity of the mounting parts under a front bulkhead. Background technique [0002] There are the following two structures in the connection structure between the engine compartment of a traditional passenger car and the mounting plate under the front bulkhead: [0003] 1. If figure 1 , Figure 1a and Figure 1b As shown, the connection structure between the passenger car engine compartment and the lower mounting plate of the front bulkhead includes the dash panel 1', the left front wheel cover 2', the right front wheel cover 5' and the lower mounting plate of the front bulkhead 3' the front bulkhead The lower mounting plate, the left front wheel house 2' and the right front wheel house 5' are respectively fixed at the bottom of the left and right ...

AI Technical Summary

Problems solved by technology

[0003] 1. If figure 1 , Figure 1a and Figure 1b As shown, the connection structure between the passenger car engine compartment and the lower mounting plate of the front bulkhead includes the dash panel 1', the left front wheel cover 2', the right front wheel cover 5' and the lower mounting plate of the front bulkhead 3' the front bulkhead The lower mounting plate, the left front wheel house 2' and the right front wheel house 5' are respectively fixed at the bottom of the left and right ends of the lower mounting plate 3' of the front bulkhead, and the dash panel 1' is fixed under the front bulkhead On the front side of the mounting plate 3', the mounting plate under the front bulkhead is not reinforced by a beam, so the connection strength cannot be guaranteed;

[0004] 2. If figure 2 , Figure 2a and Figure 2b As shown, the connecting structure of another passenger car engine compartment to the lower mounting plate of the front bulkhead includes a dash panel 1", a left front wheel house 2", a right front wheel house 5" and a front bulkhead lower mounting plate 3". The lower mounting plate of the bulkhead, the left front wheel house 2″ and the right front wheel house 5″ are respectively fixed on the left and right bottoms of the lower mounting plate 3″ of the front bulkhead, and the dash panel 1′ is fixed on the front bulkhead On the front side of the lower mounting plate 3", a crossbeam 4" is arranged between the lower mounting plate 3" of the front bulkhead and the dash panel 1", and the left and right ends of the crossbeam 4" are connected with the left front wheel house 2" and the left front wheel house respectively. Right front wheel house 5 " is fixedly connected, and like this, be provided with crossbeam 4 " between front bulkhead mounting plate 3 " and dash panel 1 " and left front wheel house 2 " and right front wheel house 5 ", crossbeam 4 " "Set between the lower mounting plate 3" of the dash panel, the dash panel 1" and the left and right wheel covers 2", the crossbeam 4" needs to be connected with the lower mounting plate 3" of the dash panel, the dash panel, the left wheel cover 2" and the right wheel 4 parts including cover 5″ are matched, and the dimensional chain is too long, which leads to the accumulation of manufacturing tolerances and superimposed out-of-tolerance problems, which affects assembly efficiency
