ABSTRACT:
A traction slip control device is disclosed including a sensor which senses a beginning slip action at at least one of the driving wheels. Connected to the sensor is a control circuit which, via an auxiliary drive, actuates the throttle valve of the drive motor in a closing manner when the sensor feeds a slip signal to the control circuit. The auxiliary drive is an articulated hydraulic control element. Its piston rod forms the push rod of a crank mechanism whose crank member is connected by means of a transmission cable with the throttle valve linkage. The accelerator pedal acts via a second transmission cable upon sector disk which is connected with the crank member via a spring. As the traction slip control device reacts, the hydraulic control element turns the crank member in order to close the throttle valve. In this process, the spring is stretched, and the crank member follows according to the position of the sector disk. The crank mechanism imitates the relationship of the delivered engine torque to the throttle valve angle.
