DIFFERENTIAL SYSTEM


  1. CONSTRUCTION


    1. Differential Pre-torque Mechanism (Models with EC63 and EC65 Manual Transaxle)


      1. A conical spring is provided between the side gear and the side gear thrust washer in the differential. The load of the conical spring applies a friction force to the sliding area, improving the straight-line stability and steering stability.

  2. OPERATION


    1. Under light load and low differential rotation speeds, due to the friction force of the sliding area, differential limit torque for the left and right wheels is achieved within the range of the side gear washer allowable load. At middle and high load ranges, which are beyond the allowable load of the conical spring, the system performs as an open differential.
