RAIL WHEEL SET AND CAR

A rail wheel set for a car which can be moved on a rail of a rail system has a bearing housing with a radial suspension for connecting the rail wheel set to the car, and two running wheels which are rotatably mounted on the bearing housing. Each wheel has a respective rail rolling surface, the shape of which is adapted to the contour of a running surface of the rail, and a respective ground rolling surface. The wheels can roll independently of each other on the running surface of the rail or on the ground. The rail wheel set is secured to a chassis of a car for transporting objects on a rail system.
