Abstract
The invention discloses a radial device of a plate-spring-type bogie. The radial device of the plate-spring-type bogie comprises carrying-saddles; the carrying-saddles are installed on axles at the left and right sides of the front and rear wheel pairs; an arch plate spring is suspended between two carrying-saddles at the same side of the front and rear wheel pairs; the middle part of the arch plate spring is upwards protruded, and a swing bolster is installed below the center of the arch plate spring. The radial device of the plate-spring-type bogie is capable of effectively solving the conflict between the curve passing performance and lateral stability of the bogie, combining the function of an elastic side bearing, greatly simplifying the structure of the radial device, and saving the distribution space for other devices of the bogie; and greatly reducing the dead-weight of the bogie, improving the carrying capacity in the same condition, and reducing the production cost.
Description
Technical field
The present invention relates to a kind of bogie truck radial device, especially a kind of leaf spring type bogie truck radial device having elastic side bearing function concurrently.
Background technology
The theory of " if wheel tangentially makes pure rolling at curve, then the abrasion between wheel track will for minimum " that the proposition substantially imagined about radial steering can be traced back to for 19 end of the centurys German Klose is proposed.After delivering to the Ph D dissertation of the founder Kalker J J of Dutch modern wheel rail adhesion theory in 1967, people are just real has had sufficient understanding to creep between wheel track and interaction.Different according to the Directing Mechanism of V-notchf Withjn of radial steering, generally can be divided into self-steering radial truck and forced-steering radial truck.
Self-steering radial truck with Scheffel bogie truck for representative.Early 1970s, the lorry radial steering that moral nationality South Africa railroad engineer Herbert Scheffel invents drops into and extensively uses, this with the radial steering of its naming based on traditional AAR lorry three piece truck, adopt diagonal member to support secondary for two U-shapeds framework is connected, same wheel links together to two upper axle boxes by the secondary framework of U-shaped, its objective is the horizontal and vertical reliable location that when guaranteeing linear running, two-wheeled is right, and curve is taken turns to rotating relatively freely along curve radial direction.This type bogie truck starts batch manufacturing in 20 century 70s mid-term, and drops into utilization in a large number.In decades subsequently, global many companies have carried out structure optimization to Scheffel bogie truck, but all do not surmount the Directing Mechanism of V-notchf Withjn of Scheffel bogie truck.
Forced-steering radial truck is the front and back wheel pair by radial pull bar, vehicle being passed to bogie truck by the corner of the relative framework of car body during curve, forces wheel to the radial position being tending towards curve.This structure is more complicated, and some passenger car bogies are applied, and roller bearing adapter stabilizer bar application is less.
The contradiction solved between bogie truck curving performance and lateral stability is the problem that vehicle dynamics studies for a long period of time always, and the appearance of radial steering efficiently solves this contradiction.But through long-term practical application, even self-steering radial device also exists complex structure, from great drawback, require higher to material and manufacturing technology level, add the productive costs of bogie truck.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of leaf spring type bogie truck radial device, that reducing deadweight and productive costs.
The present invention is achieved by the following measures:
A kind of leaf spring type bogie truck radial device of the present invention, comprise adapter, described adapter is arranged on front and back wheel on the axletree of the left and right sides, front and back wheel has arc leaf spring between two of left and right homonymy adapters, upwards swell in the middle part of described arc leaf spring, and arc leaf spring central lower is provided with bolster.
Above-mentioned arc leaf spring centre bottom or bolster top are provided with the vertical positive stop limiting arc leaf spring longitudinal extension amount.
Above-mentioned arc leaf spring center top is provided with wearing plate.
The invention has the beneficial effects as follows: effectively to solve between bogie truck curving performance and lateral stability while contradiction, have the function of elastic side bearing concurrently, can the structure of simplification radial device by a relatively large margin, be that arrangement space is saved in the installation of other device of bogie truck; And can conduct oneself with dignity by reduction bogie truck by a relatively large margin, thus under equal conditions improve load-carrying, reduce productive costs.

Wherein: 1 wheel, 2: adapter, 3 arc leaf springs, 4 bolster, 5 take turns right, 6 warp rails.
Detailed description of the invention
Below in conjunction with accompanying drawing, further detailed description is done to the present invention:
As shown in Figure 1, 2, a kind of leaf spring type bogie truck radial device of the present invention, comprise adapter 2, adapter 2 is arranged on front and back wheel on the axletree of 5 left and right sides, front and back wheel has arc leaf spring 3 between two of about 5 homonymies adapters 2, upwards swell in the middle part of arc leaf spring 3, and arc leaf spring 3 central lower is provided with bolster 4.Car body body side bearing is seated the longitudinal middle part of arc leaf spring 3, and arc leaf spring 3 has the effect of elastic side bearing concurrently.Arc leaf spring 3 centre bottom or bolster 4 top are provided with the vertical positive stop limiting arc leaf spring 3 longitudinal extension amount.Arc leaf spring 3 center top is provided with wearing plate.
As shown in Figure 3, vehicle by during warp rail 6 in centrifugal action lower body flare, the vertical force of outboard wheels 1 increases, and inboard wheel 1 vertical force reduces.Now, the arc leaf spring 3 in car body compression outside, arc leaf spring 3 longitudinal tensile strain in outside, the adapter 2 outside driving is longitudinally outer to be moved, thus outside antero posterior axis spacing strengthens; And the stressed reduction longitudinal contraction of the arc leaf spring 3 of inner side, drive inner side adapter 2 adduction, cause inner shafts spacing to reduce.Thus front and back wheel, to 5 one-tenth "eight" shape, takes turns the radial position being in warp rail 6 to 5, and bogie truck realizes smoothed curve.
Vehicle is when level tangent track runs, and arc leaf spring 3 can provide suitable vertical, horizontal rigidity, and restriction front and back wheel is shaken the head to 5, increases the horizontal location rigidity of adapter 2, thus improves the lateral stability of bogie truck.
Arc leaf spring 3 middle lower portion or bolster 4 top arrange vertical limiting block, limit the vertical deflection of arc leaf spring 3, thus limit the longitudinal extension amount of arc leaf spring 3.Arc leaf spring 3 middle upper portion arranges wearing plate, can adopt manganese steel material or synthetic material, improves resistance to abrasion.Wearing plate is connected and fixed by the connection modes such as bolt connection, welding, riveted joint, clamping and arc leaf spring 3.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
