Definitions
- the present invention relates to a work machine with a hydrostatic drive, in particular a mobile excavator according to the preamble of claim 1 and a method for operating the work machine.
- Figure 1 A block diagram of a mobile excavator according to the prior art
- control signals for the gear shift, accelerator pedal, hydraulic motor and pendulum axle lock are sent to the superstructure electronics by electrical switch signals (analog and digital); from there the control signals reach the undercarriage electronics 10 via a communication link 9.
- the solenoid valves can thus advantageously be accommodated in the undercarriage; they are controlled by means of the undercarriage electronics 10.
- transmission control block 11 is intended to arrange the transmission control block 11 directly on the transmission 8 or in another suitable place in the undercarriage. It is particularly advantageous to implement an additional “front axle shutdown” function via a solenoid valve provided in the transmission control block, which can be electrically controlled by the undercarriage electronics.
- This concept also has the advantage that the motor can be specifically adjusted to a larger swallowing volume during braking, which prevents overturning when driving downhill. If the accelerator pedal is released when driving downhill, the braking torque rises steadily over a specified time due to the adjustment of the hydraulic motor to a larger swallowing volume and the machine comes to a standstill. Overturning can thus almost be ruled out.
- the driver is forced to press the accelerator pedal to be able to drive.
- the oil conveyed from the hydraulic motor to the tank is cooled so that overheating of the units in the undercarriage is largely avoided.
- An advantageous further development of the invention provides that in the steer-by-wire unit in the uppercarriage an electric motor is used to simulate steering forces on the steering wheel in order to improve the driving experience.
- Such a steering device would make it possible to fold it out of the driver's field of vision when driving on the construction site and to operate the steering using additional joysticks. This would significantly improve visibility when working and contribute to increased safety.
- it is proposed to implement a reset behavior when the steering wheel is released when cornering in the steering device.
- Another advantage of the steer-by-wire system is that disruptive hydraulic noises are eliminated from the driver's cab.
