FOLDING ANGLE MEASURING DEVICE AND VEHICLE COMPOSITION Russian patent published in 2021 - IPC B60D1/06 B60D1/30 B60D1/62 

FIELD: measuring devices.

SUBSTANCE: group of inventions relates to a device for measuring the folding angle between a truck tractor and a trailer. The composition of the vehicle includes a truck tractor (2) and a trailer (1), which has a measuring device for measuring the angle (w_K) of folding between the tractor and a trailer (1) with a trailer hitch (9). The trailer hitch (9) includes a hitch ball (21), a ball socket (11), and a magnetic sensor (4; 4A, 4B). The hitch ball (21) has an opening (20) of the ball, in which a magnet (3) is installed, connected to the control unit (12). The ball socket (11) has a recess (10) in which a magnetic sensor is installed (4; 4A, 4B). The magnetic sensor (4; 4A, 4B) registers changes in the magnetic field (30) created by the magnet (3). Depending on the measured folding angle (w_K), an actuator (13) can be activated, which is connected to the wheels (16) of the truck tractor (2) and/or trailer (1) or the brake devices connected to them by means of the power transmission unit (14).

EFFECT: better accuracy of measuring the folding angle between the tractor and the trailer is achieved.
