Title:
RANGE CHANGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/044200
Kind Code:
A1
Abstract:
A range change device reduces shocks occurring when ranges are changed, the shocks including a shock caused by the engagement of a one-way clutch (one speed), after a D to N change operation during two-speed driving releases a brake (B-1) prior to a clutch (C-1).  If the range change device using a shift-by-wire performs the D to N change operation during two-speed driving, for example, electric signals (S1, S3, S6) flowing via an A/T control unit (U2) first releases the clutch (C-1) by using a linear solenoid valve.  After an interval of a predetermined delay time set by a delay means (U1a), the range change device drives a motor (32) of a drive mechanism (35) to change a manual valve (20) to an N-range position and drain the brake (B-1).
