Abstract
The invention relates to a device for telecontrolling a function of drives for vehicles or machines. The device consists of at least two manual gearboxes which are arranged at a distance from the drive to be controlled, the gearboxes respectively having a double acting cylinder arrangement comprising two cylinder chambers which can be actuated in counterrotation for a hydraulic flow medium, in order to control at least one function of said drive.
Claims8
A control system for controlling motor functions of a drive, comprising at least two hand switch boxes spatially separate from the drive to be controlled and which for the control of a first and second motor function of the drive have a first and second double action cylinder with two oppositely actuated cylinder chambers for a hydraulic flow medium that are connected by means of control lines carrying the hydraulic flow medium with the cylinder chambers of a first and second working cylinder allocated to said first and second motor function, whereby the outputs of the first and second double action cylinder and first and second working cylinder are parallel connected and at least one shut-off valve device is provided for in the control lines for the controlled switching on and off of the hand switch boxes wherein that parallel to the first and second working cylinder or the oppositely actuated cylinder chambers of the first and second working cylinder is a further valve, which when opened enables a hydraulic connection between the oppositely actuated cylinder chambers of the first and second working cylinder,
- wherein said first motor function is actuated by said first double action cylinder in a first swivel movement of a hand lever from a neutral position and said second motor function is actuated by said second double action cylinder in another swiveling of the hand lever.
A control system for controlling two functions, comprising
- a first double action cylinder having a first and second port,
- a first piston within said first double action cylinder,
- a first controller connected to said first piston for moving said first piston within said first double action cylinder,
- a second double action cylinder having a first and second port,
- a second piston within said second double action cylinder,
- a second controller connected to said second piston for moving said second piston within said second double action cylinder,
- a first line connected between said first port of said first double action cylinder and said first port of said second double action cylinder,
- a pair of shut off valves in said first line,
- a second line connected between said second port of said first double action cylinder and said second port of said second double action cylinder,
- a pair of shut off valves in said second line,
- a first and second working cylinder, and
- control lines connected between said first and second lines and said first and second working cylinders.
A device for remote control of a function of drives in vehicles or machines, comprising at least two hand switch boxes spatially separate from the drive to be controlled and which for the control of at least one function of the drive have a double action cylinder with two oppositely actuated cylinder chambers for a hydraulic flow medium that are connected by means of control lines carrying the hydraulic flow medium with the cylinder chambers of a working cylinder allocated to the function, whereby the outputs of the control cylinder configurations are parallel connected and at least one shut-off valve device is provided for in the control lines for the controlled switching on and off of the hand switch boxes wherein that parallel to the at least one working cylinder configuration or the oppositely actuated cylinder chambers of this configuration there is a further valve, which when opened enables a hydraulic connection between the oppositely actuated cylinder chambers of the working cylinder configuration,
- further comprising electronic control circuitry, which first enables blocking of one hand switch box by a shut-off valve0 when the hand lever of the hand switch box to be blocked is in a specified neutral position.
