Abstract
This application discloses a kind of centre of gravity to restrain compressed natural gas semitrailer, belongs to special-purpose vehicle technical field.The vehicle frame that the transport vehicle includes tractor, is connected to the tube skid of tractor rear end and is arranged at tube skid lower end, tube skid front lower ends are provided with supporting leg, vehicle frame both sides are provided with one group of tire by hanger bearing and leaf spring, the framework of the vehicle frame is I-steel, key point is that the I-steel vertical extension is 350 370mm, and the vertical extension of the hanger bearing is 370 400mm, the tractor selects low bolster-type tractor, and saddle height is 1110 1140mm.The distance between vehicle frame and ground reduce, in tractor saddle height adjustable extent, tractor saddle height is highly adapted with semitrailer, above-mentioned measure reduces the overall center of gravity of semitrailer, the coefficient that drives safely improves and energy-saving, the achievable rational economic speed per hour of vehicle traveling.
Description
Technical field
The utility model belongs to special-purpose vehicle technical field, and in particular to a kind of centre of gravity tube bank compressed natural gas semi-mounted transport
Car.
Background technology
The compressed natural gas semitrailer of centre of gravity tube bank at present is consistent with the saddle match height of existing heavy hauler, heavy
The saddle height of tractor is higher by 200mm between 1.32-1.35 rice than design specification requirement, in order to realize traffic safety,
Freight Transport of now endangering uses the transportation regulations of 60 kilometers/hour of speed limit,
After tractor of the tube bank compressed natural gas semitrailer with saddle height between 1.32-1.35 rice matches, car
In the process of running, walking curve can increase liquid centrifugal force in tank body, extremely easy to turn on one's side, and cause the accident.
GB1589-2016 standards provide that the height of heavy hauler can select between 1.11 meters -1.35 meters, are compressed for centre of gravity
The low design production of natural gas semi-mounted limit creates condition.Compressed natural gas semitrailer match height can be reduced to 1.11 meters, tractor
Saddle center of gravity reduces, and its coefficient that drives safely improves and energy-saving, the achievable rational economic speed per hour of vehicle traveling.
Utility model content
To solve the above problems, present applicant proposes a kind of centre of gravity to restrain compressed natural gas semitrailer, half is improved
The structure of trailer, lowers the center of gravity, and the saddle for the tractor for making to match matches with its height, makes semitrailer operation more
It is stable, reduce accident.
Concrete technical scheme of the present utility model is：
A kind of centre of gravity restrains compressed natural gas semitrailer, the transport vehicle includes tractor, be connected to tractor after
The tube skid at end and the vehicle frame for being arranged at tube skid lower end, tube skid front lower ends are provided with supporting leg, vehicle frame both sides
Hanger bearing and leaf spring are provided with one group of tire, the framework of the vehicle frame is I-steel, and key point is the I-shaped
Steel vertical extension is 350-370mm, and the vertical extension of the hanger bearing is 370-400mm, and the tractor selects low saddle
Tractor, saddle height 1110-1140mm.
Described I-steel vertical extension is 350mm.
Described hanger bearing vertical extension is 380mm.
The beneficial effects of the utility model are：The framework of vehicle frame uses I-steel vertical extension as 350-370mm, compared to
It is conventionally manufactured middle using the I-steel that vertical extension is 500mm, shorten the relative altitude between vehicle frame and ground, hanger bearing
Vertical extension reduces, and shortens the relative distance of tire and vehicle frame upper surface, and the distance between corresponding vehicle frame and ground reduce,
In tractor saddle height adjustable extent, tractor saddle height is highly adapted with semitrailer, and above-mentioned measure makes half
The overall center of gravity of extension transport vehicle reduces, and the coefficient that drives safely improves and energy-saving, the achievable rational economy of vehicle traveling
Speed per hour.

In accompanying drawing, 1, supporting leg, 2, tube skid, 3, vehicle frame, 4, hanger bearing, 5, leaf spring.
Embodiment
The utility model is related to a kind of centre of gravity tube bank compressed natural gas semitrailer, the transport vehicle include tractor,
It is connected to the tube skid 2 of tractor rear end and is arranged at the vehicle frame 3 of the lower end of tube skid 2, the front lower ends of tube skid 2 is set
Supporting leg 1 is equipped with, the both sides of vehicle frame 3 are provided with one group of tire by hanger bearing 4 and leaf spring 5, and the framework of the vehicle frame 3 is work
Word steel, the I-steel are 350-370mm from vertical extension, and the vertical extension of the hanger bearing 4 is 370-400mm, institute
State tractor and select low bolster-type tractor.Saddle height is 1110-1140mm.
Specific embodiment, as depicted in figs. 1 and 2, I-steel vertical extension are 350mm, are 500mm's instead of vertical extension
I-steel, height reduction 150mm, the intensity of raising vehicle frame 3, the relative altitude between vehicle frame 3 and ground reduce, bond pads component
The compound plate plate panel height degree of i-shape steel beam reduces 1/3rd, and calculated weight has dropped 25% than original, and two supporting legs 1 match somebody with somebody cross rate
Lattice can also be saved, and the overall manufacturing cost of vehicle is decreased；The vertical extension of hanger bearing 4 is down to by original 470mm
380mm, hanger self-strength improve, i.e. the relative distance of hanger bearing 4 and vehicle frame 3 shortens 90mm, by hanger bearing 4 and steel
The tire that flat spring 5 installs fixation moves up 90mm relative to vehicle frame upper surface, and vehicle frame reduces 90mm relative to ground level.
Therefore the whole height of tube bank compressed natural gas semitrailer reduces 240mm, and center of gravity of goods is reduced, and vehicle is expert at
Centrifugal force reduces when walking curve, reduces accident rate, and meets design specification, the safety coefficient of driving is improved, to realize car
Economical operation speed create conditions, conevying efficiency improve, it is energy-saving, reduce cost.
