Title: Forced differential gear
Inventor: KOIKE SHIN
IPC: F16H48/36
Filed: 1986-09-30
Abstract: PURPOSE:To reduce the turning radius of a vehicle to restrain rear wheels from projecting, by providing a mechanism for transmitting a predetermined difference in rotational speed to two shafts, and a means for coupling the transmission mechanism to the drive side when both right and left steered wheels are set at a maximum steering angle. CONSTITUTION:When a running vehicle is turned to, for example, the left with a maximum steering angle, a sensor 54 detects such a condition to energize both solenoid valves 62, 64. Further, a tube 80 is communicated with a vacuum tank 76 to move a diaphragm 90 in an actuator 66 to the left. Further, a rod 94 is rotated about the coupling point between itself and a rod 92 in an actuator 74 to shift a fork 38 to the left in order to engage a clutch 14. Further, a sun gear 18 is fixed by means of a cylindrical shaft 40 to lower the rotational speed of a planetary gear 22. With this arrangement, the rotational speed of a drive shaft 30 is lowered through the intermediary of a transmission means 46 while the rotational speed of a drive shaft 32 is raised by means of a differential gear 12.

IPC: G01C19/02
Filed: 1983-12-09
Abstract: PURPOSE:To make it possible to correct drift, by using an azimuth angle at a starting position as a drift angle, when a probe having a gyroscope comes back to the starting point after the outgoing and returning trip, and obtaining the drift angle of the outgoing path based on a ratio between the required time for the outgoing trip and the time for the outgoing and returning trip. CONSTITUTION:A probe having a gyroscope starts from a starting point A to a destination point B and reaches the destination point B after the elapse of time tn1. Then the probe returns to the starting point A after the elapse of time Tn2. At this time, and azimuth angle phid of the probe can be regarded as a drift angle. The angle phid can be regarded as an error, which occurs in proportion to time. Therefore, the drift angle phidi after a time ti from the start is obtained by phidi=ti/tn2.phid. The actual azimuth angle phi from the starting point A to the destination point B is obtained by correcting the measured azimuth angle phici by the drift angle phidi.
