Fully mechanically operated, automatic limited slip differential gear, locking device for a differential gear, and use of a locking device

摘要

There is a limited slip differential (1), comprising - a drive wheel (5) which is adapted for torque transmitting connection with an output shaft (7) of a drive torque generating drive means to drive the limited slip differential (1); - A first output shaft (15) which is connected via a differential device (11) with the drive wheel (5); - A second output shaft (17) which is connected via the differential device (11) to the drive wheel (5), and with - a locking device (3) which is adapted to limit a speed ratio between the first and the second output shaft (15, 17), wherein - the locking device (3) has a control shaft (19) proposed. The limited slip differential (1) is characterized in that - the control shaft (19) via such a torque transfer device (21) is drivably operatively connected to the drive wheel (5) that - the control shaft (19) of the drive wheel (5) at a speed is drivable, which is higher than the rotational speed of the drive wheel (5), wherein - the control shaft (19) via a first driving device (29) with the first output shaft (15) and a second driving device (31) with the second output shaft (17 ), and wherein - the first entrainment means (29) and the second entrainment means (31) are adapted to limit a speed of their associated output shafts (15, 17) to a by the control shaft (19) predetermined limit speed when one of the output shafts (15, 17) seeks a speed which is greater than the limit speed.
