Title
(EN) SUBSTANTIALLY RECTANGULAR CROSS SECTION TRANSMISSION SPRING
(FR) RESSORT DE TRANSMISSION A SECTION SENSIBLEMENT RECTANGULAIRE
Abstract
(EN)
A fluid actuated clutch assembly (10) includes a coil spring (28) which is manufactured from a substantially rectangular cross section wire. Both ends of the spring (28) are manufactured with open and ground ends (70) to ensure that the load from the spring (28) is transferred in a smooth and uniform manner.
(FR)
Un ensemble d'embrayage actionné par un fluide (10) comporte un ressort à boudin réalisé à partir d'un fil de section sensiblement rectangulaire. Les deux extrémités du ressort (28) présentent des extrémités ouvertes et rectifiées (70) pour faire en sorte que l'effort fourni par le ressort (28) soit transféré de façon progressive et uniforme.
