Abstract

The wheelset, e.g. of a bogie of a rail vehicle has a bearing housing (1) connected to a leaf-spring link (2) extending substantially in the direction of travel of the wheelset. One end of the link is fixed to a bogie side sill (3), e.g. by serrations (4) and bolts (5). In order to improve riding performance, the link (2) is connected to the bearing housing (1) by means of rubber- bonded metal elements (9). By suitable preloading of the rubber-bonded metal elements (9), e.g. by bolts (8) it is possible to vary the spring constants. One or two primary springs (13) may be provided between the housing (1) and the bogie (3). <IMAGE>

Description

SPECIFICATION A vehicle wheelset This invention relates to a wheelset, particularly but not exclusively for a bogie of a rail vehicle.
Arrangements are known in which wheelset bearings of bogies are joined to the bogie side sill by means of a leaf-spring link. One end of the link is fixedly attached to the bogie by means of screws or bolts and serrations. The bearing housing or axle box of the wheelset is also fixedly connected to the link. Spring-action is provided between the wheelset bearing housing and the bogie side sill by a primary spring. This type of wheel-set suspension suffers from drawback that the spring characteristic in the longitudinal and transverse directions cannot be freely chosen and, consequently, riding qualities cannot be optimized.
An object of the present invention is to provide a wheelset which can be connected to a bogie frame in such a manner that the spring constants in the longitudinal and transverse directions can be freely chosen in order to improve the riding performance of the bogie.
The invention provides a vehicle wheelset comprising a bearing housing connected to a leaf-spring link extending substantially in the direction of travel of the wheelset, one end of the line being adapted to be fixedly connected to a vehicle part and the other end of the link being resiliently connected to the bearing housing by means of rubber-bonded metal elements.
As a result of the resilient connection between the wheelset bearing housing and the leaf-spring link and the adjustability of the spring constants by means of preloading of the rubber-bonded metal elements, it is possible to optimize the riding properties of bogies irrespective of the spring constants of the link which, according to the state of the art, are fixed.
Two embodiments of the invention will now be described with reference to the accompanying drawings, in which: Figure 7 is a part-sectional, side elevation of a resilient connection between a leaf-spring link and a wheelset bearing housing of first bogie, Figure2 is a section taken along the iine ll-ll of Figure 1, and Figure 3 is a side elevation of a resilient connection of a second bogie.
In Figure 1, a bearing housing 1 of a bogie wheelset is connected by means of a leaf-spring link 2 to a bogie side sill 3. One end of the link 2 is connected to the bogie side sill 3 by means of screws or bolts 5, which urge serrated surfaces together so as to ensure a shear-resistant and non-hinged connection.
The other end of the leaf-spring link 2, which extends in the direction of travel of the bogie, is resiliently connected to the wheelset bearing housing 1. To this end, the wheelset bearing housing 1 is formed with a bracket 6 which straddles the springleaf link 2 from the top. A pressure plate 7 and screws or bolts 8 compress resilient connecting means comprising rubber-bonded metal elements 9.
The leaf-spring link 2 is sandwiched between two rubber-bonded metal elements 9, each consisting of rubber elements 10 bonded to first and second metal plates 1 la and 11b. In order to ensure that the connection of the rubber-bonded elements 9 to the bracket 6, the pressure plate 7 and the interposed leaf-spring link 2 is resistant to shear and torsion, cylindrical dowels or pins 1 2a to 1 2d are provided integral with the first and second metal plates 1 la and 1 it. By suitable dimensioning of the rubber elements 10 and selection of the compression force of the screws or bolts 8, it is possible to vary very substantially the spring constants of the connection both in the longitudinal and transverse directions and to obtain optimum riding conditions.Connecting one leaf-spring link 2 by means of the resilient rubber-bonded metal elements 9 not only provides good riding performance, but also permits the design of shorter bogies than is possible where two links are used. Between the wheelset bearing housing 1 and the bogie side sill 3 there is provided a primary or main spring suspension 13 shown schematically.
In Figure 2, the rubber-bonded elements 9 are held from below by the pressure plate 7 and, depending on the desired spring constant, are preloaded by means of the screws or bolts 8. Prior to installation, there is a clearance between the bracket 6 and the pressure plate 7 which is of such a size that, after the screws or bolts 8 have been fully tightened, the desired preloading in the rubber elements 10 is obtained.
where two primary springs 15a, 15b are provided between the wheelset bearing housing 1 and the bogie side sill 3, two lateral supports 14a and 14b are provided as shown in Figure 3. The connection of the leaf-spring link 2 to the wheelset bearing housing 1 is effected via the support 14a. The leaf-spring link 2 is connected under the support 14a by means of rubber-bonded elements as shown in Figures 1 and 2.
1. A vehicle wheelset comprising a bearing housing connected to a leaf-spring link extending substantially in the direction of travel of the wheelset, one end of the link being adapted to be fixedly connected to a vehicle part and the other end of the link being resiliently connected to the bearing housing by means of rubber-bonded metal elements.
2. A vehicle wheelset as claimed in claim 1, wherein the said other end of the link is interposed between rubber-bonded metal elements clamped between parts of the bearing housing.
3. A vehicle wheelset as claimed in claim 2, wherein between at ieast one of the parts of the bearing housing and the said other end of the link, there is a first metal plate fixedly held to the respective bearing-housing part, a second metal plate fixedly held to the link and a rubber element bonded between the metal plates.
