Drive system for warehouse vehicle controls motor speeds or displacement gear ratio or actuates rotation brake and changes gear depending on demand value, sensor arrangement outputs

摘要

The drive system has a shaft for driving a vehicle working movement unit and a controller that controls internal combustion engine and electric motor speeds or the displacement gear ratio or actuates a rotation brake and changes a discrete gearbox depending on vehicle operation demand value signals and sensor arrangement output signals. The drive system has a drive device and at least one unit for working movements of the vehicle with an internal combustion engine (1) displacement gearbox (2) coupled to the engine shaft, a gear assembly (24), an electric motor (3), a discrete gearbox (30) between the gear assembly output shaft and the vehicle drive wheels (34,36), a battery (26), a sensor arrangement, a shaft for driving the vehicle working movement unit and a controller (28) that controls the engine and motor speeds or the displacement gear ratio or actuates a rotation brake and changes the discrete gearbox depending on vehicle operation demand value signals and the sensor arrangement output signals.
