Embodiment Construction

[0027] Reference will now be made in detail to the exemplary embodiments illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Directional reference numbers such as "left" and "right" are for ease of reference to the drawings.

[0028] Although exemplary embodiments of the present invention will be described in connection with a particular mechanical locking differential, it should be understood that the present invention is applicable to any other type of locking differential or any other suitable mechanical device utilizing a clutch pack , or in combination with them.

[0029] figure 1 and figure 2 An example of a mechanical locking differential 1 is shown that is configured to allow two wheels on a motor vehicle to operate at different speeds and maintain free differential action (ie, unlocked mode). However, if one wheel begins to slip, the transaxle can automati...

Abstract

The invention discloses a differential, and the differential includes a case (5), a side gear (100,200), a first lock plate (1000) having a first side and a toothed side, and a second lock plate (2000) having a first side facing the case and a toothed second side facing the toothed side of the first lock plate (1000). The differential further includes a cam plate (300) between the side gear (100,200) and the first lock plate (1000) and a clutch pack (40) between the cam plate (300) and the first lock plate (1000). The cam plate (300) can comprise a splined neck (330) extending towards the first lock plate (1000), and the clutch pack (40) includes at least one active clutch disc (20) internally splined to the splined neck (330).

Description

[0001] This application claims the benefit of priority to Indian Patent Application No. 201911001157 filed on January 10, 2019, which is hereby incorporated by reference in its entirety. technical field [0002] This application relates to clutch assemblies, and more particularly to clutch assemblies having locking plates for use in, for example, mechanical locking differentials. Background technique [0003] A mechanical locking differential automatically locks the differential when a predetermined traction condition is encountered (eg, wheel speed differential exceeds a predetermined value). Mechanical locking differentials typically use an active clutch pack with a large number of clutch plates to provide the required torque capacity from the ring gear to the wheels and smooth locking action. Such a large number of clutch plates can result in extended bearing spans. [0004] In some applications, it may be desirable to reduce the span of bearings with smaller axial width...
