Abstract
The invention relates to a stud for a tyre comprising a socket-formed body portion (1), having at one end a hard metal peak (2) and at its other end a locking flange (3) retaining the stud in the tyre and being made of a light injection-mouldable material, such as plastic, the body portion (1) having a pin (4) extending towards the locking flange, with the tubular sleeve portion (5) of the locking flange fixed on top of this pin. The body portion (1) is conical so as to be clamped as a wedge into the corresponding conical sleeve portion (5).
Claims15
A stud for a tyre comprising a socket-formed body portion (1) having at one end a hard metal peak (2);
- and at the other end a locking flange (3) retaining the stud in the tyre and being made of a light material such as plastic, the body portion (1) having a pin (4) extending towards the locking flange, with a tubular sleeve portion (5) having a conical surface and being fixed on top of the locking flange, characterised in that the body portion (1) is conical over substantially its entire length with an ever-decreasing diameter so as to be clamped as a wedge into the tubular sleeve portion (5).
A tire stud, comprising:
- an ever-decreasing diameter socket-formed body portion (1) having a shoulder providing a planar surface separating a first, lower conical pin (4) part of reduced diameter from a second, upper part of increased diameter;
- a hard metal peak (2) inserted in a first end of the body portion within the second, upper part and extending into the first, lower pin part;
- a plastic locking flange (3) to retain the stud in a tire;
- a tubular sleeve portion (5) retaining the body portion with the body portion wedged into the sleeve portion;
- and
- a hollow annular space (6) between the planar surface of the body portion and an internal step portion of the sleeve portion.
