Description
Technical field
The present invention relates to vehicle-mounted metallic oil tank accessory, specifically simple, the manufacturing cost of a kind of structure and use cost is low, the vehicle-mounted metallic oil tank that improves travel safety and reliability and extend oil tank service life and chassis subtract and turn round connecting device.
Background technology
The vehicle-mounted metallic oil tank of prior art, for ensureing that an oil tank tank level relative oil tank of making peace that is in operation can not produce moment of torsion, normally arranges to subtract and turns round connecting device between oil tank and chassis.
The subtracting of current domestic and international vehicle-mounted metallic oil tank and chassis is turned round connecting device and is roughly divided into following several:
(1), common minor frame type
Common minor frame type subtracts that to turn round connecting device be increase subframe between metallic oil tank and chassis, be bolted with the crossbeam of subframe or weld bottom metallic oil tank and be fixed together, and the longeron of subframe is connected with vehicle frame elasticity by " U " shape bolt usually.This form is strengthened bottom metallic oil tank indeed through subframe, subframe is shared part moment of torsion.This connection structure is fairly simple, and also can obtain lower car load height, and application widely.But in vehicle travel process, because equipment special will bear twist moment equally, its service conditions is deteriorated.Therefore, still need to adopt various strengthening measure.Method general at present increases composite limiting device, between subframe and vehicle frame, namely adopt many places elastic limit device to reinforce it.But increase composite limiting device in any case, metallic oil tank still exists twist moment in vehicle travel process, reduce travel safety and reliability.
(2), multiple spot elastic support type
Multiple spot elastic support type subtracts that to turn round connecting device be the connection location adopting former chassis reserved, is fixed on vehicle frame, adopts metallic oil tank base plate springing, need to reinforce the cabin floor at this place simultaneously in junction by multiple point of connection.It is the simplest that this connection mode compares alternate manner, and it is also severe that it connects the operating mode of bearing in place, but can obtain lower height of wagon and lower compartment curb mass, thus, effectively can reduce car load height of gravitational center and car load offset frequency.If only adopt multiple spot elasticity to connect, when truck tanker is subject to normal acceleration, oil tank can keep good dynamic property.But when truck tanker produces lateral acceleration (turning or land locomotion operating mode) and longitudinal acceleration (accelerating or damped condition), its lateral stability and fore-and-aft stability are deteriorated, and junction can produce larger horizontal and vertical shearing force.Wherein lateral acceleration is the principal element affecting compartment stability, so need to use restraint to its lateral deformation, usual way adopts crossbeam to be connected with bottom resilient.This connection mode is applicable to the less truck tanker of tonnage, obtains certain application at present on light oil tank car.But it cannot be used in Large Oil tank car, and field of application is limited to.
(3), pipe beam fixed type
Pipe beam fixed type subtracts that to turn round connecting device be a kind of connection mode with innovative thinking, can designed by most this thought of actv. bearing torque based on pipe, and this coupling assembling is made up of Guan Liang and bracket.Adopt the fixed compartment of pipe beam, outside twist moment can be avoided in vehicle travel process to the direct effect of vehicle-mounted metallic oil tank, improve vehicle-mounted metallic oil tank service conditions, improve reliability, adopt large board-like vehicle-mounted metallic oil tank structure, reduce the deadweight of vehicle-mounted metallic oil tank and create condition, thus be widely used on some Medium or severe type truck tankers, but the more common subframe of oil tank bottom plate height is fixed pattern and is wanted high, can produce certain impact to car load height.Improve the center of gravity of car load, reduce travel safety and reliability.
(4), Guan Liang and resilient mounting composite fixed type
Guan Liang and resilient mounting composite fixed type subtract that to turn round connecting device be Guan Liang and subframe actv. are combined, thus the advantage of above-mentioned (2) and (3) two kinds of fixed forms is combined, the twist moment of oil tank can be effectively reduced, oil tank bottom plate terrain clearance is made again to be unlikely to too high, board type carriage structure can be adopted simultaneously, reduce tank structure weight, but complicated structure, and manufacturing cost and use cost is higher.
(5), 4 point type KINE-FIX Dynamic link library formulas
The world-renowned cross-country cargo carriers such as the photographer of the ARMADILLO of made by German MAN company, the Unimog of Mercedes Benz, Australia all have employed the flexible linking device that one is called " coupling of 4 point type KINE-FIX Dynamic link library mechanisms ", this bindiny mechanism utilizes the elasticity of rubber, produce two degree of freedom in the horizontal direction, when chassis tilts among a small circle, oil tank still can keep certain level, and oil tank can not produce moment of torsion, ensure that oil tank not by the impact of frame distortion.The shortcoming of this bindiny mechanism is that car load center of gravity is higher, and lateral stability is more weak.Reduce travel safety and reliability.
(6), self-containedly wholely formula is unloaded
The self-contained whole mode of unloading subtracts that to turn round connecting device be the docking mode that another kind can realize vehicle-mounted metallic oil tank and is separated with chassis, vehicle-mounted metallic oil tank is integrated on overall Self-loading-unloading pallet, the Self-loading-unloading mechanism that chassis installs additional is utilized to realize handling, this mode adopt by multiple logistical equipment, its advantage is that vehicle-mounted metallic oil tank and chassis are separable, the transport power on chassis can be made full use of, chassis can be mutually general, use flexibly, vehicle-mounted metallic oil tank pallet also can carry out the conversion of the multiple Transportation Models such as iron, water, sky.Its shortcoming is that vehicle-mounted metallic oil tank pallet quality is comparatively large, and car load useful weight is lower, and coefficient of weight efficiency is lower, and in addition, its center of gravity is also higher, and car load lateral stability is more weak.Reduce travel safety and reliability and reduction transport capacity.
In sum, connecting device complex structure is turned round in subtracting of prior art, manufacturing cost and use cost higher, travel safety and reliability low, the service life of oil tank is short.
