  • Control Strategy For Reducing Primary Drive Line Loads

    view source
  • US Patent:
    6347271, Feb 12, 2002
  • Filed:
    Sep 15, 1999
  • Appl. No.:
    09/396250
  • Inventors:
    Dan J. Showalter - Plymouth MI
  • Assignee:
    BorgWarner Inc. - Troy MI
  • International Classification:
    G06F 1700
  • US Classification:
    701 69, 701 67, 701 68, 701 90, 477 5, 477 46, 477 83
  • Abstract:
    An apparatus and method of operating an adaptive drive system of a motor vehicle which reduces drive line wear, improves safety margins and permits weight reduction in drive line components activates a clutch between a primary and secondary drive line when the vehicle is determined to be heavily loaded. The method steps include sensing the position of a throttle position sensor, sensing the instantaneous speed of a motor vehicle and computing instantaneous acceleration, determining whether the ratio of vehicle acceleration to throttle position is less than predetermined threshold value and engaging a transfer case clutch to transfer drive torque from a primary drive line to a secondary drive line. Operation of this method is transparent to the driver inasmuch as the clutch is activated when the vehicle is heavily loaded as determined by the throttle position to acceleration ratio.
  • Self-Energizing Anti-Rattle Device

    view source
  • US Patent:
    40634663, Dec 20, 1977
  • Filed:
    Jan 24, 1977
  • Appl. No.:
    5/761935
  • Inventors:
    Dan Joseph Showalter - Muncie IN
  • Assignee:
    Borg-Warner Corporation - Chicago IL
  • International Classification:
    F16F 1512
    F16D 4902
  • US Classification:
    74574
  • Abstract:
    Self-energizing anti-rattle apparatus particularly adapted for eliminating gear rattle encountered in modern manual transmissions is characterized by the provision of a device which is activated for imposing a drag on the first ratio output gear when the transmission either is in neutral with the clutch engaged or is in reverse. The device includes a lost motion mechanism to prevent imposition of the drag while the first ratio output gear is being engaged, thereby eliminating any tendency to bind during engagement.
  • Acceleration Sensitive Double Overrunning Clutch

    view source
  • US Patent:
    60623616, May 16, 2000
  • Filed:
    Nov 3, 1998
  • Appl. No.:
    9/185478
  • Inventors:
    Dan J. Showalter - Plymouth MI
  • Assignee:
    Borg-Warner Automotive, Inc. - Troy MI
  • International Classification:
    F16D 334
  • US Classification:
    192 38
  • Abstract:
    An acceleration sensitive double overrunning clutch is directionally preset by a change in speed, i. e. , acceleration, rather than relative rotation. The clutch is especially adapted for use in power transmission devices such as motor vehicle transfer cases. The clutch includes a plurality of rollers disposed in a like plurality of spaces having symmetrically arranged oblique walls formed by adjacent portions of an inner member and a concentric outer member. The rollers are arranged within a spacing cage which is coupled to an annular weight. A speed change, i. e. , acceleration or deceleration, shifts the weight and presets the cage and rollers to function in their engaged or overrunning modes in one direction or the other depending upon the direction of such acceleration.
  • Adaptive Vehicle Drive System For Extreme Operating Conditioning

    view source
  • US Patent:
    57044449, Jan 6, 1998
  • Filed:
    Dec 11, 1995
  • Appl. No.:
    8/570450
  • Inventors:
    Dan J. Showalter - Plymouth MI
  • Assignee:
    Borg-Warner Automotive, Inc. - Sterling Heights MI
  • International Classification:
    B60K 2308
  • US Classification:
    180247
  • Abstract:
    An adaptive torque control and distribution system for a motor vehicle having a transfer case, primary driveline and drive wheels and secondary driveline and drive wheels for operation in extreme off road conditions such as sand. The transfer case includes a modulating clutch and a lockup clutch disposed in parallel between its primary (rear) output and secondary (front) output. The system detects abnormally high magnitude and rapidly repeating wheel spin transients which are characteristic of operation in sand or similar highly randomly variable tractive conditions and overrides the on demand torque distribution program for a predetermined time interval. During this predetermined time interval, the transfer case lockup clutch is activated thereby coupling the primary and secondary drivelines and achieving a fifty-fifty torque split therebetween while the modulating clutch is inactive. The system and this operating mode reduces clutch and clutch operator cycling thereby reducing heat generation within the transfer case and increasing clutch and transfer case longevity.

  • Transfer Case For Four Wheel Drive Vehicles

  • US Patent:
    55205909, May 28, 1996
  • Filed:
    Apr 13, 1995
  • Appl. No.:
    8/420965
  • Inventors:
    Dan J. Showalter - Plymouth MI
    Mark A. Lindsey - Southfield MI
    Ray F. Hamilton - Farmington Hills MI
    Ronald A. Schoenbach - Farmington Hills MI
  • Assignee:
    Borg-Warner Automotive, Inc. - Sterling Heights MI
  • International Classification:
    F16H 344
  • US Classification:
    475295
  • Abstract:
    A transfer case for a part-time four wheel drive vehicle includes a planetary gear speed reduction assembly driven by the transfer case input shaft for providing high and low speed range outputs. The planetary gear assembly is disposed between and is selectively engaged by primary and secondary clutch collars, the primary clutch driving the rear (primary) output shaft in either the high or low speed ranges. The secondary clutch drives the front (secondary) output shaft through a chain drive in the low range. The clutch collars are controlled by a single (common) clutch operator. An electromagnetic clutch assembly driven by the input shaft selectively drives the front output shaft chain drive. The electromagnetic clutch functions both as a synchronizer and torque delivery device. The transfer case may be combined with a control which facilitates direct selection of vehicle drive mode.
  • Transfer Case With Four-Wheel Underdrive Operating Mode

    view source
  • US Patent:
    62034650, Mar 20, 2001
  • Filed:
    Nov 15, 1999
  • Appl. No.:
    9/439439
  • Inventors:
    Dan J. Showalter - Plymouth MI
  • Assignee:
    BorgWarner Inc. - Troy MI
  • International Classification:
    F16H 3708
  • US Classification:
    475204
  • Abstract:
    A transfer case for a four-wheel drive vehicle includes a center differential which provides a direct output in two-wheel drive and a slightly reduced speed output in four-wheel drive. In two-wheel drive, the outputs of the center differential are locked together by a clutch collar and drive torque is provided to the primary drive line only. In four-wheel drive, the clutch collar unlocks the differential and couples the output from a sun gear to a chain drive sprocket in the secondary drive line. The center differential is driven through the carrier and operates as an open differential. The ring (outer) gear drives the primary drive line and the sun (center) gear drives the secondary drive line through cooperating chain sprockets and a chain. The chain drive sprockets are of unequal size and effect a speed reduction between the drive and driven sprockets. This speed reduction is nominally the same as the speed reduction from the input to the primary output achieved through the center differential.
  • On Demand Vehicle Drive System

  • Assignee:
    Borg Warner Inc. - Troy MI
  • 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.
