The invention relates to a knuckle with a thermal protector. The invention is suitable for suspension systems, steering systems or stabiliser bars which are disposed close to an excessive heat-generating source, such as a brake. The invention essentially comprises a thermal protector (9) which is built into the knuckle. According to the invention, the upper surface of the knuckle is equipped with a series of flexible radial flat bars (10) defining a circular hole (11) therein. The aforementioned hole is coupled to a connector ring (12) which has been pre-connected to the neck (7) of the dust seal (6) which is over-injected, pressure-injected and/or glued. In this way, the above-mentioned thermal protector (9) covers the dust seal (6) in order to protect same against high temperatures generated close thereto. De aplicación para suspensiones, direcciones o barras estabilizadoras en cuyas proximidades se encuentra una fuente de generación excesiva de calor tal como un freno, incorpora fundamentalmente un protector térmico (9) integrado en la rótula que muestra en su cara superior una serie de pletinas radiales flexibles (10) que definen interiormente una abertura circular (11) que se acopla sobre un anillo de conexión (12) vinculado previamente al cuello (7) del guardapolvos (6) sobreinyectado o a presión y/o encolado, cubriendo el protector térmico (9) al guardapolvos (6) para protegerlo de las altas temperaturas generadas en el entorno. L'invention concerne une rotule trouvant une application dans des suspensions, des directions ou des barres stabilisatrices à proximité desquelles on trouve une source de génération excessive de chaleur, notamment un frein, présentant essentiellement une protection thermique (9) intégrée dans la rotule comportant, sur sa face supérieure, une série de plaques radiales souples (10) qui définissent à l'intérieur une ouverture circulaire (11) s'accouplant sur une bague de connexion (12) associée au préalable au goulot (7) de la plinthe (6) que l'on surinjecte, que l'on injecte sous pression et/ou que l'on colle, recouvrant ainsi la protection thermique (9) de la plinthe (6) en vue d'assurer sa protection lors de conditions de hautes températures générées dans son entourage.
