Abstract
The invention relates to a device for telecontrolling a function of drives for vehicles or machines. Said device comprises at least two manual gearboxes which are arranged at a distance from the drive to be controlled, said 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.
Claims5
Device for remote control of a function of drives in vehicles or machines, with at least two hand switch boxes (1, 2) spatially separate from the drive (4) to be controlled and which for the control of at least one function of the drive (4) have a double action cylinder (8) with two oppositely actuated cylinder chambers for a hydraulic flow medium that are connected by means of control lines (9,10,12, 14) carrying the hydraulic flow medium with the cylinder chambers of a working cylinder (3, 3a) allocated to the function, whereby the outputs of the control cylinder configurations are parallel connected and at least one shut-off valve device (15) is provided for in the control lines for the controlled switching on and off of the hand switch boxes (1, 2), characterized in that parallel to the at least one working cylinder configuration (3, 3a) or the oppositely actuated cylinder chambers of this configuration there is a further valve (17), which when opened enables a hydraulic connection between the oppositely actuated cylinder chambers of the working cylinder configuration (3).
Device as claimed in one of the foregoing claims, characterized in that in each of the two lines leading to the oppositely actuated cylinder chambers of the positioning cylinder configurations there is a shut-off valve (15).
Device as claimed in one of the foregoing claims, characterized by connections (16) on the control lines (9, 10) for adding hydraulic fluid and for bleeding of the lines.
