Differential gear provided with differential lock mechanism

摘要

A differential mechanism regulating device which is mechanically connected to two manipulators is miniaturized. When a first cable and a second cable are pulled, a collecting member moves its position. As a result of this movement, the collecting member tilts a portion of an arm by way of a rod. As a result, a differential lock is released. The operation of the first cable and the operation of the second cable can be merged by the collecting member, and it is sufficient to connect only a collecting transmission member to the arm. The connection between the arm and the collecting transmission member can be simplified thus realizing the miniaturization of the differential mechanism.

主权项

1. A differential mechanism regulating device, comprising:
a differential mechanism which transmits a drive force inputted from a power unit to left and right drive shafts and which generates a difference in rotational speed between left and right wheels connected to the left and right drive shafts; a differential lock mechanism attached to said differential mechanism and configured to lock said differential mechanism into a non-differential state; a switching means attached to said differential lock mechanism, said switching means configured to switch a state of said differential lock mechanism between an operation state and a release state; a first cable connected at a first end of said first cable to a first manipulator, the first manipulator being configured to actuate said switching means via said first cable; a second cable connected at a first end of said second cable to a second manipulator, the second manipulator being configured to actuate said switching means via said second cable; a collecting member provided between said first and second cables and said switching means, a second end of said first cable and a second end of said second cable being connected to said collecting member; and a collecting transmission member which connects said collecting member and said switching means to each other, wherein an operational force is transmitted from the first manipulator and the second manipulator to the switching means via said collecting member and said collecting transmission member.
