Abstract
A vee-shaped transmission belt (1) has a main core (10) in the shape of a trapezium made of natural and/or synthetic rubber, containing at least one substantially inextensible cord (20) extending over the entire length of the belt (1). At least one layer (14) of fiber-reinforced elastomer is placed in contact with the core (10) near the long base (2) of the trapezium. At least one thin external coating layer (18) envelopes the entirety of the core (10) and the reinforced layer (14) over the entire length of the belt (1). A peripheral cushion (17) made of an elastomer that is elastically softer and more deformable than the core (10) surrounds the core (10) and the layer (14) of fiber-reinforced elastomer and is surrounded by the coating layer (18).
