Description
Technical Field
The utility model relates to the technical field of tank trucks, in particular to a tank truck with low residual rate.
Background
The suspension system is a general term for all force-transmitting connecting devices between the frame and the wheels of the automobile, and has the functions of transmitting force and torsion acting between the wheels and the frame, buffering impact force transmitted to the frame or the automobile body from an uneven road surface, and attenuating vibration caused by the impact force so as to ensure that the automobile can run smoothly.
The existing tank truck suspension system is generally pure plate spring suspension or pure air bag suspension, the air bag suspension is good in comfort, and a lifting device is easily added to lift an axle when the axle is in no load, so that the landing area of a tire is reduced, and the abrasion (especially the abrasion during steering and braking) and oil consumption of the tire are reduced. However, the air bag suspension is expensive, 3-4 times as expensive as the leaf spring suspension, and many users can only use the leaf spring suspension in consideration of the price. The plate spring suspension has low cost and high bearing capacity, but has poor comfort, can not lift an axle when in no load, and can not reduce the abrasion and oil consumption of tires.
The plate spring suspension is an elastic element which is most widely applied in an automobile suspension system, and is an elastic beam which is approximately equal in strength and formed by combining a plurality of alloy spring pieces which are equal in width but unequal in length (the thicknesses can be equal or unequal). Its advantages are simple structure, high reliability, low cost and easy maintenance. It is an elastic element of suspension system and a guide device of suspension system, one end of it is hinged with vehicle frame, it can transfer various forces and moments and determine the runout track of wheel, at the same time, it also has a certain friction damping action. The leaf spring suspension achieves three purposes, so that the leaf spring suspension is widely used for non-independent suspensions.
According to international 18564.1-2019 part 1 of tank truck for road transportation of liquid dangerous goods: the technical requirement of the metal normal-pressure tank body 6.2.3.2 requires that a flange for installing an emergency cut-off valve is directly welded on a cylinder body or a seal head, so that the diversion trench parts for reducing the surplus rate cannot be used, the surplus rate of the tank truck is increased, and the transportation efficiency and the economic benefit are directly reduced.
Fig. 1 and 2 are that guide grooves are arranged under the old standard, and although the bottom of the tank body is welded with parts such as wave blocking plates and the like, the tank body is deformed by welding, liquid can flow into the guide grooves due to the arrangement of the guide grooves, so that the liquid is prevented from accumulating at the deformed position, and the residual rate is low.
Fig. 3 and 4 show that under the new standard, a diversion trench cannot be arranged, welding deformation occurs when the bottom of the tank body is welded with parts such as a wave-blocking plate, and liquid is accumulated at the deformed part due to the welding deformation, so that the residual rate is increased.
The inclination of the increase jar body and ground, can be effectual with the jar interior liquid outflow, reduce the residual rate, but at present most general air hang, the leaf spring hangs, the mixed suspension of air leaf spring can't realize increasing the inclination.
Fig. 7 is a schematic view of a common air suspension, and the air suspension can adjust the height of an air bag according to road conditions during driving to realize the smoothness of a vehicle, but when the vehicle stops and unloads, the height of the air bag is a fixed value and cannot be lifted, so that the inclination of a tank body and the ground is the state of the tank body, and the residual rate cannot be reduced.
Fig. 8 and 9 are schematic views of initial and lifting states of air suspension with a single axle lifting function, the suspension lifting axle function is intended to lift an axle when the vehicle is in idle load, so that tires are not in contact with the ground, abrasion of the tires is reduced, and oil consumption is reduced.
Fig. 10 is a schematic diagram showing an air suspension lifting state with two axle lifting functions, the function is the same as that in fig. 9, the axle lifting function is used for lifting the axle when the vehicle is in idle load, so that the tire is not in contact with the ground, the abrasion of the tire is reduced, and the oil consumption is reduced.
Fig. 11 is a schematic diagram of a conventional leaf spring suspension, when a vehicle stops to unload, the height of the leaf spring is a fixed value and cannot be lifted, so that the inclination of the tank body and the ground is a self state, and the residual rate cannot be reduced.
See fig. 12 and 13 for a schematic view of the initial and lifted state of the hybrid air and leaf spring suspension assembly with two axle lift functions, as in fig. 8 and 9.
In summary, the increase of the inclination and the reduction of the residual rate cannot be realized no matter the air suspension is a common air suspension or a plate spring suspension, or the air suspension or the air plate spring hybrid suspension is provided with a single shaft or two shafts for lifting.
