Limited Slip Differential (LSD): Structure

This V/C type LSD has outer plates and inner plates incorporated one after the other between the differential case and side gear (LH). The former is spline-coupled to the inside of the differential case at its outer periphery and the latter is spline-coupled to the outer circumference of the side gear (LH) at its inner periphery.

The inner plates are held in position by spacer rings while the outer rings slide in the axial direction along the spline.

The space between the differential case and side gear (LH) is filled with a mixture of high viscosity silicone oil and air and hermetically sealed with X-ring.
