Description
Technical field
The utility model relates to vehicle-mounted metallic oil tank accessory, specifically is a kind of simple in structure, manufacturing cost and use cost is low, the vehicle-mounted metallic oil tank that improves travel safety and reliability and prolong oil tank service life and chassis subtract and turn round connecting device.
Background technology
The vehicle-mounted metallic oil tank of prior art can not produce moment of torsion for guaranteeing oil tank tank level relative an oil tank of making peace that is in operation, and normally is provided with to subtract between oil tank and chassis and turns round connecting device.
At present subtracting of domestic and international vehicle-mounted metallic oil tank and chassis turned round connecting device and roughly is divided into following several:
(1), common subframe formula
Common subframe formula subtracts that to turn round connecting device be to increase subframe between metallic oil tank and chassis, the metallic oil tank bottom is fixed together by bolted connection or welding with the crossbeam of subframe, and the longeron of subframe is connected with vehicle frame elasticity by " U " shape bolt usually.This form is actually by subframe to be strengthened the metallic oil tank bottom, makes subframe share the part moment of torsion.This connection structure is fairly simple, and also can obtain lower car load height, uses very extensive.But in the vehicle ' process,, make its service conditions variation because equipment special will bear twist moment equally.Therefore, still need adopt various strengthening measures.Method in common is to increase compound inhibiting device at present, promptly adopts the many places elastic limit device to come it is reinforced between subframe and vehicle frame.But increase compound inhibiting device in any case, still there is twist moment in metallic oil tank in the vehicle ' process, has reduced travel safety and reliability.
(2), multiple spot resilient mounting formula
Multiple spot resilient mounting formula subtracts turns round the connection location that connecting device is employing former chassis reservation, and the metallic oil tank base plate is fixed on the vehicle frame by a plurality of point of connection, adopts springing in the junction, needs simultaneously the cabin floor at this place is reinforced.It is the simplest that this connection mode is compared alternate manner, and it is also abominable that it connects the operating mode of bearing in the place, but can obtain lower height of wagon and lower compartment curb mass, thereby, can reduce car load height of gravitational center and car load offset frequency effectively.If only adopt multiple spot elasticity to connect, when truck tanker was subjected to normal acceleration, oil tank can keep the better dynamic performance.But when truck tanker produces lateral acceleration (turning or the land locomotion operating mode) and longitudinal acceleration (quickening or damped condition), its lateral stability and fore-and-aft stability variation, the junction can produce bigger horizontal and vertical shearing force.Wherein lateral acceleration is the principal element that influences compartment stability, so need use restraint to its lateral deformation, usual way is to adopt crossbeam to be connected with bottom elasticity in the compartment bottom front.This connection mode is fit to the less truck tanker of tonnage, obtains certain application at present on the light oil tank car.But it can't be used in the 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, and it is can this thought of actv. bearing torque designed to be based on pipe, and this coupling assembling is made up of Guan Liang and carriage.Adopt the fixed compartment of pipe beam, in the vehicle ' process, can avoid of the direct effect of outside twist moment to vehicle-mounted metallic oil tank, improved vehicle-mounted metallic oil tank service conditions, improved reliability, adopt big board-like vehicle-mounted metallic oil tank structure, reduce vehicle-mounted metallic oil tank deadweight and created condition, thereby in some, on the heavy duty oil tank car, obtained using widely, but the more common subframe of oil tank bottom plate height fixedly pattern wants high, can produce certain influence to the car load height.Improve the center of gravity of car load, reduced travel safety and reliability.
(4), the compound fixed type of Guan Liang and resilient mounting
The compound fixed type of Guan Liang and resilient mounting subtracts that to turn round connecting device be that Guan Liang and subframe actv. are combined, thereby combine the advantage of above-mentioned (2) and (3) two kinds of fixed forms, can effectively reduce the twist moment of oil tank, make the oil tank bottom plate terrain clearance be unlikely to too high again, simultaneously can adopt board-like carriage body construction, reduce tank structure weight, but the structure more complicated, and manufacturing cost and use cost is higher.
(5), the dynamic interconnection system of 4 point type KINE-FIX
World-renowned cross-country cargo carriers such as ARMADILLO, the Unimog of Mercedes Benz of Germany MAN company, Australian photographer have all adopted a kind of being called the flexible linking device of " coupling of the dynamic bindiny mechanism of 4 point type KINE-FIX ", this bindiny mechanism utilizes the elasticity of rubber, produce two degree of freedom in the horizontal direction, when the chassis tilts among a small circle, oil tank still can keep certain level, and oil tank can not produce moment of torsion, has guaranteed that oil tank is not subjected to the influence of vehicle frame distortion.The shortcoming of this bindiny mechanism is that the car load center of gravity is higher, lateral stability a little less than.Travel safety and reliability have been reduced.
(6), the self-contained whole formula of unloading
The self-contained whole mode of unloading subtracts that to turn round connecting device be that another kind can be realized the docking mode that vehicle-mounted metallic oil tank separates with the chassis, vehicle-mounted metallic oil tank is integrated in whole from loading and unloading on the pallet, utilize loading and unloading of installing additional on the chassis from the handing device realization, this mode is adopted by multiple logistical equipment, its advantage is that vehicle-mounted metallic oil tank and chassis are separable, can make full use of the transport power on chassis, the chassis can be general mutually, use flexibly, vehicle-mounted metallic oil tank pallet also can carry out the conversion of multiple Transportation Models such as iron, water, sky.Its shortcoming is that vehicle-mounted metallic oil tank pallet quality is bigger, and the car load useful weight is lower, and coefficient of weight efficiency is lower, and in addition, its center of gravity is also higher, the car load lateral stability a little less than.Travel safety and reliability and reduction transport capacity have been reduced.
In sum, the connecting device complex structure is turned round in subtracting of prior art, and manufacturing cost and use cost are higher, and travel safety and reliability are low, and the service life of oil tank is short.
