摘要

A gearbox (15) connects the drive engine (14) with one axle (rear axle 4), which is provided with a gear change unit (18). An axle load detection unit (pressure sensor 23, 24, spring displacement sensor 39, 40) is respectively assigned to the front and rear axles (3, 4). They respectively transmit an axle load signal dependent on the axle load. A vehicle standstill detection unit gives a standstill signal if the vehicle is at a standstill. The axle load signals and the standstill signal are supplied to a control unit (29). With the supply of a standstill signal and at least one axle load signal, which exceeds a specified axle load, a gear limiting signal is given. This signal is transmitted to a high gear blocking unit. ADVANTAGE - With exceeding of specified axle loading at one axle only, forced limitation of max. vehicle speed occurs.
