International Classification:

B60K 17344

US Classification:

180248

Abstract:

An on demand vehicle drive system monitors vehicle performance and operating conditions and controls torque delivery to the vehicle wheels. The system includes a plurality of speed and position sensors, a transfer case having primary and secondary output shafts driving primary and secondary axles and a microcontroller. The sensors include a vehicle speed sensor, a pair of primary and secondary drive shaft speed sensors, and brake and driveline status sensors. The transfer case includes a modulating electromagnetic clutch controlled by the microcontroller which is incrementally engaged to transfer torque from the primary output shaft to the secondary output shaft. When the speed of either the front or the rear drive shafts overruns, i. e. , exceeds, the speed of the other drive shaft by a predetermined value related to the vehicle speed, indicating that wheel slip is present, clutch current is incrementally increased to increase clutch engagement and torque transfer to the secondary axle. When wheel slip is reduced below the predetermined value the current to the clutch is incrementally reduced.

Inventors:

Joseph W. Beckerman - Livonia MI

Assignee:

Massey-Ferguson Inc. - Detroit MI

International Classification:

G05G 510

US Classification:

74476

Abstract:

A transmission control useable with a transmission of the type having a first change gear mechanism for establishing a plurality of drive speeds and a second change gear mechanism for establishing either a forward or reverse drive for each of said plurality of drive gears, the transmission control including stop means capable of preventing the transmission from operating in one or more selected reverse speeds to prevent high speed reverse operation of a vehicle employing the transmission.

Assignee:

Massey-Ferguson Inc. - Detroit MI

International Classification:

F16D 312
F16D 364

US Classification:

64 14

Abstract:

A flexible coupling which permits both rotational and axial movement. An elastomeric member is sandwiched between two coupling members and is held in place in such a manner that the coupling members do not contact each other. Thus, each of the coupling members includes an elongated portion provided with projections which are received within cavities defined by radially extending fingers formed on the elastomeric member. The couplings are angularly offset 90. degree. with respect to each other. Portions of the elastomeric member are held in compression between ends of the elongated portion and retainers by screw fasteners. The retainers and the screw fasteners associated with one coupling member do not contact the other coupling member.

Assignee:

Massey-Ferguson Inc. - Detroit MI

International Classification:

G05G 918

US Classification:

74473R

Abstract:

This specification describes a multiple throw selector apparatus for use in change speed gearing which includes speed ratio shift rails to engage synchronized clutches and a range lever which engages an unsynchronized clutch. The range shift rail is moved between its various operative positions directly by a selector member. The ratio shift rails are actuated by the selector member through a pivoted link thereby increasing mechanism advantage between control lever and ratio shift rails.

Abstract:

An on demand vehicle drive system monitors vehicle performance and operating conditions and controls torque delivery to the vehicle wheels. The system includes a plurality of speed and position sensors, a transfer case having primary and secondary output shafts driving primary and secondary drive shafts, differentials and axles and a microcontroller. The sensors include a vehicle speed sensor, a pair of primary and secondary drive shaft speed sensors, and brake and driveline status sensors. The transfer case includes a modulating electromagnetic clutch comprising a primary, cone clutch assembly which functions as a pilot device to actuate a secondary, disc pack clutch assembly. The electromagnetic clutch is controlled by the microcontroller which is incrementally engaged to transfer torque from the primary output shaft to the secondary output shaft. When the speed of either the front or the rear drive shaft overruns, i. e. , exceeds, the speed of the other drive shaft by a predetermined value related to the vehicle speed and other variables, indicating that wheel slip is present, clutch current is incrementally increased to increase clutch engagement and torque transfer to the secondary drive shaft.
