Title
(DE) TRETKURBELANTRIEB FÜR EIN FAHRRAD
(EN) PEDAL CRANK DRIVE MECHANISM FOR A BICYCLE
(FR) ENTRAINEMENT PAR PEDALIER POUR BICYCLETTE
Abstract
(DE) Es wird ein Tretkurbelantrieb für ein Fahrrad mit zwei über eine Tretkurbelwelle (1) drehfest miteinander verbundenen Tretkurbeln(2), it einem auf einem Lageransatz (5) einer der beiden Tretkurbeln (2) anschlagbegrenzt drehbar gelagerten Kettenrad (3) und mit wenigstens einer in Umfangsrichtung verlaufenden Druckfeder (12) uwischen dieser Tretkurbel (2) und dem ein Widerlager (14) für die Druckfeder (12) tragenden Kettenrad (3) beschrieben. Um vorteilhafte Konstruktionsbedingungen zu schaffen, wird vorgeschlagen, da$g(b) die das Kettenrad (3) tragende Tretkurbel (2) mit einem gegen das Kettenrad (3) vorstehenden Ansatz (16) in eine Ausnehmung (17) des Kettenrades (3) eingreift, die in beiden Umfangsrichtungen Drehanschläge (18, 19) für diese Tretkurbel (2) bildet.
(EN) The invention relates to a pedal crank drive mechanism for a bicycle, comprising two pedal cranks (2) rotationally fixed to one another by means of a pedal crankshaft (1), a chain wheel (3) that is rotationally mounted on a bearing stop (5) of one of the two pedal cranks (2) and limited by a stop and at least one pressure spring (12) extending in peripheral direction between said pedal crank (2) and the chain wheel (3) carrying a counter bearing (14) for the pressure spring (12). In order to provide advantageous constructional conditions, the invention provides that the pedal crank (2) carrying the chain wheel (3) engages with a stop (16) projecting against the chain wheel (3) in a recess (17) of said chain wheel (3), which forms rotational stops (18, 19) for said pedal crank (2)in both peripheral directions (18, 19)
(FR) L'invention concerne un entraînement par pédalier pour bicyclette comportant les éléments suivants : deux manivelles (2) solidaires en rotation par l'intermédiaire d'un axe (1), un pignon à chaîne (3) limité par une butée et monté rotatif sur un bord de palier (5) de l'une des deux manivelles (2), au moins un ressort de pression (12) placé dans le sens circonférentiel entre ladite manivelle (2) et le pignon à chaîne (3) pourvu d'un contre-palier (14) pour le ressort de pression (12). Pour créer des conditions de réalisation favorables, la manivelle (2) servant de support au pignon à chaîne (3) est en prise dans un évidement (17) du pignon à chaîne (3), avec une pièce (16) en saillie contre le pignon à chaîne (3), cet évidement formant dans les deux sens circonférentiels des butées de rotation (18, 19) pour cette manivelle (2).
