摘要： A synchronization and engagement device (1) for a gear change (2) of a motor vehicle is provided with: a hub (17), which is fixed and coaxial with respect to a shaft (3) of the gear change; a toothed driving ring (44), fixed to an idle or neutral gear (9) of the gear change (2); a first conical friction surface (47), carried by one (9) between the driving ring and the gear; a floating toothed synchronizing ring (39), which has a second conical friction surface (40) mated to the first conical surface (47); and at least one engagement member (54), which is angularly fixed with respect to the hub (17), is able to slide axially under the action of a control device (16), and has a cylindrical toothing (55), designed to render the hub (17) angularly fixed with respect to the driving ring (44). The engagement member (54) is set in a radial position that is more internal with respect to the conical friction surfaces (40, 47), whilst the cylindrical toothing (55) of the engagement member (54) is an external toothing.
