US 5,413,015 A · Automotive vehicle differential assembly

Abstract

A differential assembly having a driving case enclosing a pair of driving members operably coupled with a pair of driven members. The driven members are secured to output shafts and the driving members are forcibly driven by a driving shaft having its opposite ends in engagement with the driving case. The mid-section of the driving shaft passes through an eccentric or angled aperture formed by cooperating arcuate surfaces provided in opposing surfaces of the driving members. The driving members and the driven members are urged together respectively by double oppositely wound concentric springs bearing against a pin carried in an elongated hole coextensively provided in opposing surfaces of adjacent driving members of both pairs. Inspection and access openings are provided in passageways and in the oblong cross-section of part of the passageways.

Dependent claims

A differential mechanism comprising:

output means;
driving means in spaced relationship to said output means;
driven means operably responsive to said driving means for powering said output means;
said driving means having a pair of clutch driving members coaxially disposed with respect to each other and having opposing spaced-apart surface faces;
biasing means interposed between said driving surface faces comprising at least a pin in alignment with a spring assembly consisting of two concentric springs bearing against one end of said pin;
said springs and said pin in axial alignment disposed in an elongated passageway jointly provided in each of said pair of clutch drive members;
each of said clutch drive members has inspection and access openings communicating with said passageway so as to expose said springs and said pins respectively;
and
said spring passageway is of oblong configuration in transverse cross-section.
