FIELD: machine building.SUBSTANCE: locked differential includes central annular cam element (130) freely rotating and supported inside central annular drive element (116) without using any locking device, such as a stop ring. Central cam element (130) is supported in place in longitudinal direction owing to displacement forces applied to elements (122, 124) of the coupling, which are located on opposite sides of central drive element by means of cylindrical compression springs concentrically located on outer side relative to side gears (118, 120) respectively and by means of support rings (132, 134) that are connected to the coupling elements. Central cam element (130) and central drive element (116) have external and internal adjacent peripheral surfaces respectively that are smooth, solid and continuous. Support rings (132, 134) are connected so that they can be turned at their far ends with the coupling elements by means of one-piece annular external ribs (132a, 134a) that are continued inside the corresponding grooves continued in bored surfaces of walls.EFFECT: invention allows simplifying design and assembly of a differential and reducing its cost.4 cl, 18 dwg |
