Title: DIFFERENTIAL COMPRISING A DECELERATION DEVICE
Abstract:
Differentials having a clutch pack for applying a decelerating torque to the output shafts of the differential are known from the prior art. The aim is to design the deceleration device in such a way that deceleration is effective and the deceleration device is easy to service. To achieve said aim, the deceleration device (2) is a drum brake that includes a passive element having a cylindrical frictional surface and also includes brake shoes (25), the frictional surfaces of which can come into contact with the cylindrical frictional surface of the passive element (21, 30). The passive element (21, 30) can be a brake drum (21) or a radial brake disk (30), the cylindrical edge of which acts as a frictional surface. According to the invention, the passive element (21, 30) is fastened to the differential cage (9) and/or to one of the shafts (7, 11, 12). The brake shoes (25) are pivotally retained on a support plate (16, 31) that is externally fastened to the differential casing (2).
