  • Lifting bogie for a vehicle
    Patent number: 4842302
    Abstract: The invention relates to a lifting bogie for a vehicle, comprising on both sides of the vehicle a rocker arm (4) which is journalled on a shaft (5) and in one end of which an auxiliary shaft (6) is journalled for a bogie wheel (12). When the bogie is lifted by means of a hydraulic cylinder (8) by the action of the transmission lever (7), the rocker arm (4) is pivoted so that the bogie is caused to be lifted up. In order to make the use of the lifting bogie move versatile, the transmission lever (7) is according to the invention connected to the rocker arm (4) by means of a cotter pin (18) also at a point in which the transmission lever (7) is supported on the rocker arm (4) when the bogie is being lifted. The rocker arm (4) can thereby be pivoted by means of the double-acting hydraulic cylinder (8) so that it lifts the driving shaft off the ground by means of a pendant (3 ) and a bogie spring (2).
