摘要： The invention relates to a vehicle (2) comprising
- a chassis (4) that is moveable in a driving direction (3),
- two rear wheels (6) moveably carrying the chassis (4) on the rear side seen in the driving direction (3),
- two front wheels (5) moveably carrying the chassis (4) on the front side seen in the driving direction (3),
- a steering wheel (7) for turning a steering column (26) around a rotation axis (28) for steering the front wheels (5), and
- a steering angle sensor (32) for measuring a rotation angle (8) of the steering column (26) around the rotation axis (28) with an encoder (34) that is stationary to the steering column (26) and with a magnet sensor (36) that is disposed axially displaced (72) from the encoder (34) on the rotation axis (28),
- wherein the encoder (34) includes a first magnet (38) with a top side (48) directed to the magnet sensor (36) and a second magnet (40) attached to the first magnet (38) opposite to the top side (48), wherein at least the first magnet (38) includes a recess (52) starting from the top side (48), wherein each magnet (38, 40) is magnetized orthogonal to the rotation axis (28), and wherein regarding from the magnetizations (42, 44), the first magnet (38) and the second magnet (40) are displaced against each other in rotation direction (46),
characterized in that
the recess (52) has a depth (56) that is lower than an axial
thickness (61) of the first magnet (38).
