Definitions

  • the invention relates to a car body with a chassis with at least one sprung axle or Shaft, especially bogie, for rail vehicles, such as. B. funiculars.
  • Such trolleys are known from WO 89/12566 and EP 0365 489 A2 and have the disadvantage that heavy bogie frames are required, and that for comfortable cross suspension and complicated for self-steering of the axles Devices must be arranged. Lead with poor substructure Deviations from the ideal rail position for bogie deformation or reduced driving comfort and increased wear.
  • the invention has set itself the task of the disadvantages mentioned encounter and create a lightweight design for chassis. Due to the Use of radially displaceable spring-damper elements, which are the side or above the wheels, the vertical forces are directly in the Carriage body or directed into the bogie frame. With the spring-damper elements it is preferably air springs. The longitudinal and lateral forces are suspended or damped handlebars in the central pivot or headed directly into the car body. A major advantage is that the invention both the longitudinal and the transverse forces or their resilient Effects are dampened.
  • the invention is characterized in that the axis / s or shaft / s by Handlebars arranged radially around a pivot point connected to the car body is / are and that the running axis / n or shaft / n through preferably parallel to the track arranged connecting rods with the car body or with each other is / are connected, whereby horizontal forces corresponding to the execution of the Handlebars and connecting rods in the arranged on the car body Pivot are guided undamped or initiated and that the vertical support of the wheels against the car body over the Barrel or shaft or the connecting rods or over the handlebars Spring elements, preferably air springs.
  • Other essential features of the invention are specified in subclaims 2 - 8.
  • Fig. 1 and 2 shows a bogie in elevation and plan
  • Fig. 3 the Elevation of an axle undercarriage.
  • Fig. 1 shows in plan a bogie of a rail vehicle in which the individual running axles 6 via damped or sprung in the axial direction Handlebar 4 are connected to the pivot 5 of the bogie.
  • the handlebars 4 are optionally sprung and / or damped in the axial direction and have if necessary, at their connections to the individual components 6 and 5 elastic eyes 7, 7 'or are the bolt connections in elastic sleeves stored so that slight deformations within the connection during the Driving can be compensated.
  • the handlebars 4 can also be used as shock absorbers be trained.
  • the wheels 1 of the axes 6 are in the vertical direction Spring-damper elements 2 (Fig. 2) which are designed, for example, as an air spring are supported.
  • the single ones Wheels 1 consecutive wheels 6 are by a resilient and / or damped Connecting rod 3 connected, for example, by a telescopic tube, in particular in suspended and / or damped in the axial direction, or a connecting rod with at least an elastically lined eye is formed.
  • Both the connecting rods 3 and the links 4 are arranged in pairs, the links 4 being inclined to one another in plan otherwise essentially parallel and the connecting rods 3 of the axes 6 to each other are provided in parallel, in particular in the direction of travel 8.
  • the handlebars 4 are fastened to a sleeve 10 which surrounds the component 5 in the form of a pivot vertical direction on component 5 is vertically displaceable, so that the car weight only is introduced into the chassis via the springs 2.
  • both the connecting rods 3 and the handlebar 4 of rigid elements are formed that have little freedom of movement at the support point exhibit.
  • at least one of the components 3 or 4 is preferably made with elastic Lanyards stored, or designed directly as a telescope, which means longer spring travel be made possible. In most cases, the lining of the eyes with one is sufficient elastic mass.
  • the handlebars 4 and / or the connecting rods 3 as a telescopic damper element can be changed by changing the hydraulic pressure in the individual damper elements influence the spring stiffness or damper constant, so that the inclination of the car body can be influenced during rapid cornering, for example by reducing the hydraulic pressure on the inside of the curve and on the Outside the curve is increased compared to normal pressure.
  • These measures can increase the maximum cornering speed.
  • the use is essential to the invention of radially displaceable springs, preferably of air springs which move laterally or over the Wheels are arranged.
  • the arrangement of the handlebars in a triangle to the central pivot point essential, the handlebars can also be unsprung, for example the connecting bolts are stored in elastic sleeves.
  • the construction is not limited to the use of a bogie, it can also be used uniaxial trolleys (Fig. 3) are used, in which the handlebars 4 at one central point in the car body 9 and the half connecting rods 3 between the car body 9 and axis 6 are articulated. These measures equalize the Barrel axis 6 to the rail conditions without major deformations in the car body or introduced into the chassis frame.
  • the invention enables a defined radial self-steering axis adjustment depending on of the existing transverse force using spring-loaded and possibly damped Connecting rods 3 and the handlebar assembly described above.
