Abstract
A high-speed freight car bogie for rolling stocks is composed of wheel-set system, adapter, side frame and bolster. It is characterized in that: there is a swing device between the bolster and the side frame to cause them swinging or rotating relatively. The swing device can be ball, column, half ball, half column or shapes correlative with ball and column. The amount of the devices can be 1-4. Simultaneously, the bolster and the two side frames are restricted by the swing device to form a H truss with certain diamond resistant rigidity in the horizontal. The left and right side frames equals to two suspender hanging elastic components of the axle box. They drive the bolster (spring swing mechanism) to make lateral synchronous hunting. The invention adopts the spring hanging swing mechanism to assure the bogie having light mass under spring, high critical speed, superior vehicle lateral performance, which can meet the requirements for railway to develop 160km/h high-speed freight cars.
Description
Technical field
The present invention relates to the preassembling that a kind of goods train vehicle is used, refer in particular to the bogie truck that a kind of goods train vehicle is used.Belong to the preassembling of railway vehicle, be mainly used in the novel high speed railway goods train bogie.
Background technology
At present, generally to be divided into one be the three-major-items formula bogie truck (as Barber) that spring mounted framework type bogie truck (as Y25) and secondary spring hang to railway goods train bogie.Wherein, it is light that the framework type bogie truck has a unsprung weight, and the wheel track action is firmly little, the advantage that critical speed is high, but the transverse elasticity of the type bogie truck is only provided by journal box spring, and very limited, lateral performance is not good enough during high-speed cruising; Traditional three-major-items formula roller bearing adapter stabilizer bar diamond resistant rigidity is little, poor performance, and running velocity is not high, and the bogie truck unsprung weight is big simultaneously, and the abrasion between wheel track are serious.Had a kind of on the basis of traditional three-major-items formula roller bearing adapter stabilizer bar afterwards, increase spring plank and shaken the swing type bogie (as Swingmotion) that seat waits parts composition teeter mechanism, the transverse elasticity of the type bogie truck is provided by central spring and the combination of teeter mechanism, horizontal excitation that bogie truck can be subjected to and car body are isolated, improved the lateral direction of car performance greatly, but this bogie truck unsprung weight is big, the impact of wheel track when having strengthened high-speed cruising.(publication number is Chinese patent ZL01275171.5: CN2517641) disclose " a kind of high-speed freight car bogie ", comprise that wheel is to, framework and bolster, wherein, the framework of described bogie truck and the wheel between be provided with the axle box suspension gear, be provided with the dish type foundation brake rigging between this framework and the axletree, the end of axletree is provided with the mechanical type anti-skid device, described bolster links by means of central rubber metal pad spring suspension device and framework, also be provided with the longitudinal traction pull rod device between the two ends of this bolster and framework, both sides, bolster top are provided with the suspension type The Constant-Contact Resilient Side Bearings.This bogie truck can improve the diamond resistant rigidity of bogie truck, for taking turns to reasonably vertical, located lateral rigidity are provided, improve the vertical of vehicle and lateral vibration performance, guarantee the normotopia between bolster and the framework, and can improve the hunting critical speed of bogie truck, make highest running speed of train can reach 160km/h, guarantee that bogie truck has stable deceleration and stopping performance.But above-mentioned patent does not consider from spring suspension that still so improving anti-water chestnut property, still there are some limitation in the aspects such as low tractive performance of optimizing bogie truck, so performance still can not meet the demands, running velocity is not high; Or the bogie truck unsprung weight is big, and the abrasion between wheel track are serious, therefore necessary this is improved.
Summary of the invention
The objective of the invention is to: the deficiency according to existing high-speed freight car bogie, provide a kind of both transverse elasticitys good, and the bogie truck unsprung weight is little, can adapt to the novel high speed roller bearing adapter stabilizer bar combined method and the device of 160km/h highest running speed requirement.
Described goal of the invention is achieved through the following technical solutions: a kind of high-speed freight car bogie, comprise that wheel is to system, axle box elastic parts, bogie side frame and bolster, it is characterized in that: bogie truck has integrated the constructional feature of rigid frame bogie truck and swing type bogie, swinging gear on the spring is hung on the axle box elastic parts, can allow bolster and bogie side frame produce swinging gear on the spring of relatively swinging or rotating being provided with on the axle box elastic parts.But having realized the combination of swinging gear swinging technique on axle box suspension technology and the spring, is the advanced roller bearing adapter stabilizer bar of a kind of mechanism of action.
In addition, the axle box elastic parts comprises axle box and fluid power elastic element, and axle box is arranged on the wheel set bearing, the fluid power elastic element is arranged on the axle box, the fluid power elastic element is glued together by top, bottom and the vulcanization of rubber, and inside is provided with damping panel, the internal cavities filling liquid.This fluid power elastic element has the function of carrying and vibration damping simultaneously.When fluid power elastic element up-down vibration, cause the inner chamber flow of liquid, play damping of vibrations thereby flowing liquid produces resistance during by damping panel.
The longitudinal tie device links together axle box and bolster by the rubber ball cover, has realized the longitudinal elasticity location between axle box and bolster, has improved axle box longitudinal register rigidity.
Disc brake mainly is made up of unit brake cylinder, brake disc, clamp, brake lining etc.
The mechanical type anti-skid device is located at the axletree end, because of the excessive locking wheel of braking force, causes wheel sliding when preventing car brakeing.
Structurally integrated the advantage of rigid frame bogie truck (as Y25) according to high-speed freight car bogie provided by the present invention with swing type bogie (as Swingmotion).Swinging gear on the spring being hung on the axle box elastic parts, but realized the combination of swinging gear swinging technique on axle box suspension technology and the spring, is the advanced roller bearing adapter stabilizer bar of a kind of mechanism of action, has following characteristics and advantage:
1, adopts axle box suspension technology, reduced unsprung weight significantly, reduced the vertical action of wheel track firmly, improved the vertical dynamic performance of vehicle.
But 2, adopt swinging gear swinging technique on the spring, improved the critical speed of vehicle operating, improved the transversal dynamic performance of vehicle.
3, adopt the axle box elastic parts, elastic element is not organically combined with there being the abrasion damping, improved the cushioning performance of vehicle.
4, between axle box and bolster, be provided with the longitudinal tie device, improved axle box longitudinal register rigidity.
5, adopt disc brake, improved braking ratio.
6, adopt the mechanical type anti-skid device, wheel sliding when preventing that braking force is excessive.
In sum, a kind of suspension swing type bogie of axle box provided by the invention, because it adopts the special swinging gear that hangs on the spring, guaranteed that this bogie truck unsprung weight is light, the critical speed height, wheel track action is firmly little, and the lateral direction of car superior performance has satisfied the needs of railway development 160km/h High-Speed Freight Vehicle.
