Definitions

• the invention relates to a bogie, preferably for high wheelset loads, with idler wheels mounted on axles that do not rotate.
• a ⁇ very severely limits the transferable wheel loads, so that the known bogie can only be used for very light vehicles. Furthermore, a separate wheel carrier is provided for each wheel on the bogie. In order to ensure that the axles of the left and right wheels are aligned, comparatively complex assembly devices are necessary which make assembly and subsequent maintenance of the bogie difficult.
• the rotating axle of the wheelset requires, in addition to separate axlebox bearing housings to accommodate the axlebox mounting, an additional bearing in the center of the axlebox, on the bearing housing of which the elements for transverse guidance of the axlebox are arranged. This also makes the wheelset guide multi-parted, heavy and complex.
• the bearing located in the center of the wheelset is difficult to access for relubrication work. In the case of a bearing replacement, the entire wheel set must even be removed from the bogie and completely dismantled.
• the invention has for its object to provide a bogie-capable bogie for high wheel loads with less manufacturing and maintenance, which otherwise avoids the disadvantages described above.
• Z5 Fig. 1 is a schematic side view of a bogie with a portion of the body
• FIG. 2 shows the top view of the bogie according to FIG. 1
• 3 shows the top view of the bogie according to FIG. 1 with a modified arrangement of the coupling elements
• FIG. 4 shows the top view of the bogie according to FIG. 1 with wishbones
• Fig. 5 shows an embodiment for the spring support on the axle
• Fig. 6 shows another embodiment for the spring support on the axle set.
• the car body 1 is supported on a crossbar 8, which in turn is supported on the axles 6 and 7 via the springs 9 and 10.
• the wheels 2, 3, 4 and 5 are rotatably supported independently of one another, whereby the bearing can be arranged in the wheel hub, so that separate wheelset bearing housings - / ⁇ O are not necessary.
• the joints being preferably ball joints, spherical joints or rubber-metal parts with the same effect.
• the wheelset axes 6, 7 can only move in the vertical direction relative to the crossbeam 8 and rotate about axes which are essentially parallel to the rail.
• the rods 1 1 and 12 so
• the wheelset axis 6 can additionally rotate about the vertical axis through point A passes. Accordingly, the wheelset axis 7 can rotate about the vertical axis that passes through point B.
• the springs 9 and 10 can designed for high wheel loads.
• Their connection to the wheelset axles 6 and 7 can be designed in a simple manner because of the fact that the wheelset axles 6 and 7 are rotationally fixed with respect to an axis which is essentially transverse to the rails and to the wheels 2, 3, 4 and 5. that the leaf springs 9 and 10 can freely change their length during compression (Fig. 5).
• the continuous axles 6 and 7 ensure that the axes of rotation of the left and right wheels of an axle are exactly aligned, which does not change even during later maintenance work.
