Description
Technical field
A kind of torpedo hot metal mixer car bogie device described in the utility model is a kind of bogie truck that is used on the metallurgical vehicle metallurgy vehicle.
Background technology
China's torpedo hot metal mixer car design at present, manufacturing have had vicennial history, and the bogie device that is used to carry and transport mainly contains two kinds, and a kind of is two axle truck, and a kind of is three axle truck.The problem that exists is exactly that load-carrying capacity is low poor with curve negotiation ability; And be not with hand brake device, can not satisfy the requirement that increasing customer requirements increases the parking hand brake device.The inside and outside spring height of resting the head on spring in addition is the same, inside and outside like this spring stress inequality, and the outer spring frangibility is damaged; The spring filament diameter of inner spring is little, is 22mm; The material of inner spring is 50CrVA, makes the inner spring load-carrying capacity too poor like this.In recent years, along with the continuous increase of iron and steel output, the load-carrying capacity that the increases torpedo hot metal mixer car development tendency that is inevitable promptly requires torpedo hot metal mixer car under the prerequisite that guarantees the oad minimum, increase its load-carrying capacity and curve negotiation ability to greatest extent, and guarantee the safety and stability of parking.At existing problem in the above-mentioned prior art, a kind of later-model torpedo hot metal mixer car bogie device of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of torpedo hot metal mixer car bogie device of research and design, thereby solves that existing torpedo hot metal mixer car bogie truck load-carrying capacity is low, curve negotiation ability is poor, occur the problem of coaster when stopping.A kind of torpedo hot metal mixer car bogie device described in the utility model is made up of bogie side frame group, bolster group, wheel shaft assembling, axle box assembling.The one group of wheel shaft centre that it is characterized in that the wheel shaft assembling is provided with the hand brake disc that press-fits form.The free height that is contained in the inner spring of the pillow spring between bogie side frame group (1) and the bolster group (2) is 277.5mm, and number of active coils is 7.5 circles, and rigidity is 1030N/mm; The free height of outer spring is 273mm, and number of active coils is 3.5 circles, and rigidity is 2806N/mm.Pillow spring described in the utility model adopts the stronger 60Si2CrVA alloy steel material of anti-shear ability.The spring filament diameter of inner spring is 25mm.The effect that the utility model finally reaches is exactly that loading is after the bogie truck cartridge, inner spring is at first stressed, when its superelevation 4.5mm guarantees that whole running gear completes, cluster spring just in time is in coefficient critical conditions, after car load completion and molten iron inject, carried jointly by inside and outside spring, stressed ratio is 1: 2.5, reduce the stressed of outer spring effectively, thereby solve the problem that outer spring fractures.
Principle of work of the present utility model is: the load of torpedo hot metal mixer car tank body is delivered on the little body center plate of this bogie truck by devices such as driving and driven end device and upper and lower vehicle frame and cartridges, pass through the combined action of bolster, pillow spring, bogie side frame, axle box then, two groups of wheels that will be distributed to bogie truck at last from the various load of torpedo hot metal mixer car equably are to last, and wherein combination pillow spring plays crucial effects.
The utility model is the two axle truck that a kind of center of gravity is low, load-carrying capacity is strong, assurance has good curve negotiation ability, and consider that now increasing customer requirements increases the parking hand brake device, the brake disc of hand braking usefulness is set on the wheel shaft of bogie truck, cooperates hand brake can guarantee torpedo hot metal mixer car parking safety.
The utlity model has following advantage and effect:
1, to have overall dimensions little for this bogie truck, the advantage that whole mechanism load-carrying capacity is strong, and the load-carrying capacity of single group bogie truck is 100t, it is maximum that to allow load on axle journals be the 50t/ axle.
2, bogie side frame, bolster intensity height have good load-carrying capacity, and the inside and outside spring carrying of combination pillow spring distributes rationally, has better damping effect.
3, the setting of hand brake disc device is for safe in operation has been created condition.
The utlity model has advantages such as novel structure, load-carrying capacity is strong, the parking safety and stability is reliable, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
Description of drawings
The utility model has three accompanying drawings, wherein
Accompanying drawing: 1, a kind of torpedo hot metal mixer car bogie device structural representation front view
Accompanying drawing: 2, a kind of torpedo hot metal mixer car bogie device structural representation birds-eye view
Accompanying drawing: 3, a kind of torpedo hot metal mixer car bogie device structural representation lateral plan
Among the figure: 1, bogie side frame group 2, bolster group 3, wheel shaft assembling 4, pillow spring 5, axle box assembling 6, hand brake disc
The specific embodiment
Specific embodiment of the utility model adopts bogie side frame group 1, bolster group 2, wheel shaft to assemble 3 three-major-items split-type structurals as shown in drawings, has good maintainability.Two groups of wheel shaft assemblings 3 connect into an integral body by axle box assembling 5, bogie side frame group 1, from the load on torpedo hot metal mixer car top by bolster group 2 and be arranged on bolster group 2 and bogie side frame group 1 between pillow spring 4 be delivered to the wheel shaft fit on, wherein rest the head on spring and play buffer action, prevent that impact load from damaging other parts.The key problem in technology point has two places, and the one, in one group of wheel shaft centre of bogie truck the hand brake disc 6 that press-fits form is set, the braking force from hand brake is delivered on wheel and the track equably, guarantee parking safety.The 2nd, pillow spring 4 reasonable in design.The spring filament diameter of the number of turns, free height and inner spring by adjusting inside and outside spring makes that cluster spring rigidity reduces, active coils increases, and guarantees that spring has better carrying and cushion characteristic.Concrete measure is as follows:
1. the free height with outer spring is designed to 273mm, and number of active coils is 3.5 circles, and rigidity is 2806N/mm;
2. the free height of inner spring being designed to the 277.5mm number of active coils is 7.5 circles, and rigidity is 1030N/mm;
3. the spring filament diameter with inner spring is designed to 25mm, adopts the stronger 60Si2CrVA alloy steel material of anti-shear ability;
The effect that finally reaches of design is exactly that loading is after the bogie truck cartridge like this, inner spring is at first stressed, when its superelevation 4.5mm guarantees that whole running gear completes, cluster spring just in time is in coefficient critical conditions, after car load completion and molten iron inject, carried jointly by inside and outside spring, stressed ratio is 1: 2.5, reduce the stressed of outer spring effectively, thereby solve the problem that outer spring fractures.
In addition by adjusting the outer shape and the structural materials of parts such as bogie side frame group 1, bolster group 2, finally reach load-carrying capacity maximum, oad minimum, purpose that the cartridge carrying surface is minimum, become the first-selected parts of big load on axle journals torpedo hot metal mixer car.
