2. 5 Comparison with other types of differentials
Other means are also known for modifying the operative connection between drive axles to provide for the transfer of additional torque to the drive axles collectively. For example, many limited-slip differentials provide for preloading friction clutches to oppose the transfer of torque between drive axles. This frictional pre-load represents a particular minimum magnitude of resistance which must be overcome to permit any relative rotation between drive axles which may interfere with the operation of anti-lock braking systems. Also, since frictional forces are continually active to resist differentiation, the friction clutches tend to wear, resulting in a deterioration of intended differential performance.
In contrast to the limited-slip's continuous magnitude of frictional resistance to differentiation, the
torque biasing characteristic of the Torsen differential provides for a maximum ratio of torque
distributions between drive axles. For instance, as the amount ... ... ... . yadda yadda yadda
