Description
Technical field
The utility model relates to special purpose vehicle manufacturing technology field, especially a kind of subframe for liquid tank semi-trailer.
Background technique
Existing liquid tank semi-trailer subframe is integrated welding or high stringer 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 biggish weight transfer occurs in turning for vehicle,
Biggish 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.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of liquid tank semi-trailer subframes, it can solve semi-mounted
Tank truck tail 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 solution of the utility model is: this liquid tank semi-trailer subframe includes peace
Axle suspension, left stringer, right vertical beam and suspension crossbeam on axle suspension seat, the suspension crossbeam are that top surface is arcwall face
Arc hang crossbeam, the axle suspension seat is respectively welded at left stringer and right vertical beam bottom；The arc suspension crossbeam weldering
It connects and connects the axle suspension seat of left and right on the axle suspension；Pass through arc respectively at arc suspension crossbeam both ends
Shape suspension cross-beam connecting plate is connect with left stringer and right vertical beam；The arc suspension cross-beam connecting plate is welded on a left side by triangle muscle
On stringer and right vertical beam；Suspension cross member reinforcing plate is welded at the top of the arc suspension crossbeam.
In above-mentioned technical proposal, more specifically scheme may also is that offer in the middle part of the arc suspension crossbeam and be used for
The fixed through-hole of pipeline, top is arcwall face, and the top two sides are provided with to connect with the left stringer 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 suspension riveting transverse beam connecting hole.
Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
The utility model can flexibly cope with tank due to the structure of novel auxiliary frame being assembled into using arc suspension beam structure
The arrangement of body tail portion oil pipe and divide storehouse, as far as possible reduction longitudinal beam height, while by reducing subframe longitudinal beam structure
Vehicle height is also reduced, vehicle center of gravity is thereby reduced, that is, improves vehicle in zig zag and bumpy road driving process
Safety coefficient, compared to high stringer perforating tube structure materials, less, weight gentlier can more meet the light-weighted development of vehicle at this stage
Trend.

Fig. 5 is that subframe connects partial enlarged view at A in Fig. 3；
Fig. 6 is that arc hangs beam structure schematic diagram in Fig. 3；
Fig. 7 is that arc hangs cross-beam connecting plate structural schematic diagram in Fig. 3, Fig. 5；
Fig. 8 is vehicle and subframe high-level schematic.
Figure label indicates are as follows: 1, oil discharge pipe, 2, triangle muscle, 3, arc suspension cross member reinforcing plate, 4, arc suspension crossbeam
Connecting plate, 5, arc suspension crossbeam, 6, axle suspension seat, H, vehicle height, H2, subframe height, HA, prior art subframe
Highly, HA1, prior art stringer and beam height, HB, the utility model subframe height, HB1, the utility model stringer and
Beam height.
Specific embodiment
The present invention will be further described with reference to the accompanying 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
It spends the reduction of H2 and reduces, thereby reduce whole vehicle center.But in the existing old-fashioned subframe of Fig. 1 and Fig. 2, oil discharge pipe 1 is put
Seated position need to cross frame cross, can not reduce height of chassis above ground, i.e., can not reduce prior art stringer and beam height HA1 to drop
Low prior art subframe height HA.
The liquid tank semi-trailer subframe of Fig. 3 to Fig. 7 includes the axle suspension being mounted on axle suspension seat 6, Zuo Zong
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 stringer 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, offering the through-hole fixed for pipeline in the middle part of arc suspension crossbeam 5, top is arcwall face, the top
The chamfering that two sides are provided with convenient for connecting with the left stringer and right vertical beam；Pass through arc respectively at arc suspension 5 both ends of crossbeam
Suspension cross-beam connecting plate 4 is connect with left stringer and right vertical beam；As shown in fig. 7, arc suspension 4 top surface of cross-beam connecting plate be set as with
Arc hangs the identical arcwall face of 5 top radian of crossbeam, and bottom offers the connecting hole for riveting with arc suspension crossbeam 5；
Arc suspension cross-beam connecting plate 4 is welded on left stringer and right vertical beam by triangle muscle 2；Arc hangs the top welding of crossbeam 5
There is suspension cross member reinforcing plate 3.
I.e. the utility model solves the problems, such as to exist by improving the structure of the old-fashioned subframe of Fig. 1 and Fig. 2；This is practical
Novel 1 placement location of oil discharge pipe can be sunken under frame cross, so as to reduce height of chassis above ground, i.e. the utility model stringer and cross
Depth of beam HB1 is lower than prior art stringer and beam height HA1, to reduce the utility model subframe height HB, most final decline
Low vehicle height, thereby reduces vehicle center of gravity, solves the problems, such as flow container tail part storekeeper road arrangement, improves vehicle
The safety coefficient of traveling has reached the light-weighted effect of vehicle.
