<p>1534227 Differential gear control EATON CORP 15 Sept 1977 [22 Sept 1976] 38594/77 Heading F2D The rate of rotation of the crown wheel 34 of a vehicle differential is monitored by a sensor 200, a control 208 detects acceleration of the crown wheel greater than a predetermined value, an indication of wheel slip, to cause an actuator 210 to engage a lock-up positive clutch. The clutch comprises a sleeve 86 having teeth which engage teeth of a gear 88 and teeth 87 which engage teeth 82 of a differential side gear 54. The gear 88 is connected to the crown wheel 34 through a multi-disc friction coupling loaded by springs 102, the coupling slipping if excess torque is present. The sensor 200 may be photoelectric or electromagnetic. The actuator 210 may operate pneumatically, electrically or hydraulically. The control 208 may be fluidic or electronic. The differential may alternatively be an interaxle differential (Fig. 4, not shown). The clutch can be operated manually. The clutch may be held engaged by a time delay after engagement.</p> |
