A sensor for measuring the difference between the velocity and/or position of a vibration-suppressing cylinder and that of a piston connected to a piston rod and moving back and forth inside the cylinder in a dashpot for motor vehicles. The sensor consists of a permanent magnet and of a winding in the form of a cylindrical coil and operating in conjunction with the magnet. The magnet is connected directly or indirectly to one of the mutually moving components and the winding is connected directly or indirectly to the other. The component that the magnet (5) rests against and the component that the winding (7) rests against constitute a complete circuit that carries the magnet's field.

Sensor for measuring the difference between the velocity of a cylinder

A sensor for measuring the speed and/or position of a piston in relation to that of the cylinder it moves inside of in a dashpot of shock absorber for motor vehicles. The sensor consists of a permanent magnet (10) connected to the cylinder (1) and of a sensor winding (9) in the form of a cylindrical coil that operates in conjunction with the magnet. The sensor winding has leads at the ends. Additional leads for a shorter winding component (7 and 8) extend out separately upstream of the ends of the sensor winding.

The invention concerns a vibration-absorber sensor for the semi-actively controlled chassis of a motor vehicle wherein the relative velocity of the wheel mass to the body mass is measured with a sensor winding and a permanent magnet and processed in a circuit.
