The upper surface of 22 is concordant, the lower surface of front main longitudinal grider body 21 from be abutted against connection end to connect end be
Inclined-plane；Shape according to front main longitudinal grider body 21 and the shape of rear main longitudinal grider body 22, by lightening hole
Being set to two kinds of shapes, be divided into the first lightening hole 4 and the second lightening hole 5, the first lightening hole 4 is positioned at
On front main longitudinal grider body 21, and the free end main longitudinal grider body 21 forward of the past main longitudinal grider body 21
Connection end arrangement, the second lightening hole 5 is positioned on rear main longitudinal grider body 22, the second lightening hole 5 edge
The length direction arrangement of rear main longitudinal grider body 22.Main longitudinal grider body is divided into front main longitudinal grider body 21 He
Rear main longitudinal grider body 22, sets on front main longitudinal grider body 21 according to the shape of front main longitudinal grider body 21
Put the first lightening hole 4, according to the shape of rear main longitudinal grider body, rear main longitudinal grider body 22 is arranged
Second lightening hole 5, it is possible to while alleviating the weight of main longitudinal grider body 2, reduces to main longitudinal grider originally
The impact of the intensity of body 2.
According to the size of front main longitudinal grider body 21 free end, the first lightening hole 4 is set to circular hole,
Specifically, the equal diameters of the first lightening hole 4 of the multiple circles on front main longitudinal grider body 21 is many
First lightening hole 4 of individual circle arranges along the length direction of front main longitudinal grider body 21.In the process of use
In, the pressure part that compartment is applied on front main longitudinal grider body 21 circle by the first lightening hole 4
Week dispersion, another part is disperseed by the interval between adjacent two the first lightening holes 4.Subtract first
Repeated hole 4 is arranged to circle, before alleviating while the weight of main longitudinal grider body 21, reduces front master
The impact of the intensity of longeron body 21.
In order to increase the intensity at the edge of the first lightening hole 4, it is preferable that can be at multiple first lightening holes
The edge of 4 is provided with flange 7, and flange 7 is cylindric, and the internal diameter of cylindric flange 7 is equal to
The diameter of the first lightening hole 4, one end of cylindric flange 7 and the side of front main longitudinal grider body 21
Connecting, the flange 7 on all first lightening holes 4 is positioned on the same side of front main longitudinal grider body 21,
The axle center of cylindric flange 7 and the axis coinciding of the first corresponding lightening hole 4.To main longitudinal grider originally
During body 2 welds, the cylindric flange 7 of the edge of the first lightening hole 4 can discharge
The internal stress produced in welding process, prevents front main longitudinal grider body 21 from affecting itself because of deformation
Intensity；In use, the setting of cylindric flange 7 can increase main longitudinal grider body 2 and exist
Bearing capacity at first lightening hole 4, and then it is prevented from front main longitudinal grider body 21 at the first loss of weight
It is deformed at hole 4, the intensity of main longitudinal grider body 21 before improving.The setting of flange 7 can improve
The intensity of front main longitudinal grider body 21, and then the bearing capacity of front main longitudinal grider body 21 can be improved.
Before affecting to prevent the first lightening hole 4 from concentrating on front main longitudinal grider body 21, main longitudinal grider is originally
The intensity of body 21, it is preferable that by the first lightening hole 4 along between the length direction of front main longitudinal grider body 21
Every arrangement, as it is shown in figure 1, the first lightening hole 4 is led forward from the free end of front main longitudinal grider body 21
The connection end of longeron body 21 is spaced, between the axle center of adjacent two the first lightening holes 4 away from
Diameter from the first lightening hole 4 more than twice.In use, before compartment applies pressure at
On main longitudinal grider body 21, the pressure part being applied on front main longitudinal grider body 21 passes through the first loss of weight
The edge dispersion in hole 4, another part is disperseed by the interval between adjacent two the first lightening holes 4.
Being spaced by multiple first lightening holes 4 on front main longitudinal grider body 21, before alleviating, main longitudinal grider is originally
The impact of intensity on front main longitudinal grider body 21 can be reduced while the weight of body 21, make commercial car
Main longitudinal grider can preferably play its effect.
In order to make the first lightening hole 4 i.e. can play the effect of the weight alleviating front main longitudinal grider body 21
The most do not affect the intensity of front main longitudinal grider body 21, it is preferable that the quantity of the first lightening hole 4 arranged
Being five, five the first lightening holes 4 are from the free end main longitudinal grider body forward of front main longitudinal grider body 21
The connection end of 21 is spaced, and between the axle center of two the first lightening holes 4 of arbitrary neighborhood away from
From equal；The edge of five the first lightening holes 4 is provided with flange 7, and flange 7 is cylindric,
One end of flange 7 is connected with the side of front main longitudinal grider body 21, turning on five the first lightening holes 4
Limit 7 is positioned on the same side of front main longitudinal grider body 21, and the axle center of flange 7 subtracts with corresponding first
The axis coinciding of repeated hole 4.In use, compartment applies pressure at front main longitudinal grider body 21
On, the pressure part being applied on front main longitudinal grider body 21 limit by five the first lightening holes 4
Flange 7 at edge disperses, and another part is disperseed by the interval between adjacent two the first lightening holes 4.
The quantity of the first lightening hole 4 it is set to five and is uniformly arranged, making adjacent two the first lightening holes 4
Between interval uniform force, therefore, it is possible to subtract while the weight of main longitudinal grider body 21 before alleviating
The impact of the little intensity on front main longitudinal grider body 21, it is ensured that the normal use of commercial car main longitudinal grider.
According to the shape of rear main longitudinal grider body 22, the second lightening hole 5 is set to abnormity circle structure,
