Locking device for chassis frame in track carrier, has extender wheel provided at connection bolt of side plate equipped in chassis frame

摘要

The locking device has an extender wheel (1) provided at a connection bolt (2) of a side plate (3) equipped in a chassis frame. The chassis frame reduces a play between the extender wheel and the track carrier-bottom flange (4) to zero by rotating around an axis of the connection bolt. The chassis frame assembles a defined pressure between the extender wheel and track carrier-bottom flange. An outer contour is provided with a stable elastic support.
