Description
Technical field
The present invention relates to special purpose vehicle manufacturing technology fields, especially a kind of subframe for liquid tank semi-trailer.
Background technology
Existing liquid tank semi-trailer subframe is integrated welding or high longeron perforating tube structure form, such subframe manages tail portion
Road arrangement is restricted big；Height is higher, and vehicle center of gravity is therefore also impacted, and larger weight transfer occurs in turning for vehicle,
Larger resultant force-the component generated, that is, reduce stability；Therefore, that there are tail portion pipe arrangements is difficult, whole for such liquid tank semi-trailer
The car weight heart is high, from it is great a series of problems, such as.
Invention content
Technical problem to be solved by the invention is to provide a kind of liquid tank semi-trailer subframes, it can solve semi-mounted flow container
Tailstock portion pipe arrangement is difficult, vehicle center of gravity is high, from a series of problem such as great.
To solve the above-mentioned problems, the technical scheme is that：This liquid tank semi-trailer subframe includes to be mounted on
Axle suspension, left longeron, right vertical beam on axle suspension seat and suspension crossbeam, the suspension crossbeam are the arcs that top surface is arcwall face
Shape hangs crossbeam, and the axle suspension seat is respectively welded at left longeron and right vertical beam bottom；The arc suspension beam welding exists
The axle suspension seat of left and right is connected on the axle suspension；It is outstanding by arc respectively at arc suspension crossbeam both ends
Cross-beam connecting plate is hung to connect with left longeron and right vertical beam；The arc suspension cross-beam connecting plate is welded on left longeron by triangle muscle
On right vertical beam；It is welded with suspension cross member reinforcing plate at the top of the arc suspension crossbeam.
In above-mentioned technical proposal, more specifically scheme can also be：It offers and is used in the middle part of the arc suspension crossbeam
The fixed through-hole of pipeline, top are arcwall face, and the top both sides are provided with to connect with the left longeron and right vertical beam
Chamfering.
Further：Arc suspension cross-beam connecting plate top surface is set as identical as arc suspension beam top radian
Arcwall face, bottom offer for the arc hang riveting transverse beam connecting hole.
Due to the adoption of the above technical scheme, the present invention has the advantages that：
The present invention can flexibly cope with tank body tail portion oil due to the structure of novel auxiliary frame being assembled into using arc suspension beam structure
The arrangement of pipe and divide storehouse, reduce longitudinal beam height as far as possible, is also reduced while by reducing subframe longitudinal beam structure
Vehicle height thereby reduces vehicle center of gravity, that is, improves vehicle in zig zag and the safety coefficient of bumpy road driving process,
Compared to high longeron perforating tube structure materials, less, weight gentlier can more meet the light-weighted development trend of vehicle at this stage.

Highly, HA1, prior art longeron and beam height, HB, subframe height of the present invention, HB1, longeron of the present invention and crossbeam are high
Degree.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples：
Fig. 8 is vehicle and subframe height relationships schematic diagram.As can be seen from Figure, vehicle height H is with subframe height H2
Reduction and reduce, thereby reduce whole vehicle center.But in the existing old-fashioned subframe of Fig. 1 and Fig. 2, position is placed by oil discharge pipe 1
Frame cross need to be crossed by setting, and can not reduce height of chassis above ground, i.e., it is existing to reduce to reduce prior art longeron and beam height HA1
There is technology subframe height HA.
The liquid tank semi-trailer subframe of Fig. 3 to Fig. 7 includes axle suspension, Zuo Zong on axle suspension seat 6
Beam, right vertical beam and suspension crossbeam, suspension crossbeam are that the arc that top surface is arcwall face hangs crossbeam 5, and axle suspension seat 6 is respectively welded
In left longeron and right vertical beam bottom；Arc suspension crossbeam 5, which is welded on the axle suspension, connects the axle suspension seat 6 of left and right
It connects；As shown in fig. 6,5 middle part of arc suspension crossbeam is offered for the fixed through-hole of pipeline, top is arcwall face, the top
Both sides are provided with the chamfering convenient for being connect with the left longeron and right vertical beam；Pass through arc respectively at 5 both ends of arc suspension crossbeam
Suspension cross-beam connecting plate 4 is connect with left longeron and right vertical beam；As shown in fig. 7, arc suspension cross-beam connecting plate 4 top surface be set as with
Arc hangs the identical arcwall face of 5 top radian of crossbeam, and bottom offers the connecting hole for being riveted with arc suspension crossbeam 5；
Arc suspension cross-beam connecting plate 4 is welded on by triangle muscle 2 on left longeron and right vertical beam；Arc hangs the top welding of crossbeam 5
There is suspension cross member reinforcing plate 3.
It is i.e. of the invention to solve the problems, such as to exist by improving the structure of the old-fashioned subframe of Fig. 1 and Fig. 2；Emptying of the present invention
1 placement location of pipe can be sunken under frame cross, so as to reduce height of chassis above ground, i.e., longeron and beam height HB1 ratios of the present invention
Prior art longeron and beam height HA1 are low, to reduce subframe height HB of the present invention, eventually reduce vehicle height, into
And vehicle center of gravity is reduced, it solves the problems, such as flow container tail part storekeeper road arrangement, improves the safety coefficient of vehicle traveling,
The light-weighted effect of vehicle is reached.
