Definitions
- the present invention relates to a differential limiting device, and more particularly, to a friction-based differential limiting device using a pressure generating unit.
- a differential device that transmits the power of the engine to the left and right drive wheels with a difference.
- a differential is an indispensable device when driving on a curved road, but when one wheel falls into a mud or sand, most of the power is transferred to the missing wheel, causing the missing wheel to spin faster and spin down. On the contrary, the power is hardly transmitted to the wheel which has not fallen, and only the missing wheel which receives a lot of power is getting more and more lost and finally it can not come out.
- a differential limiter is a device that solves this shortcoming of the differential. That is, the differential limiting device refers to a device that limits the differential action.
- the differential limiter developed to date is classified into mechanical lock, automatic intermittent friction clutch, torque responsive friction clutch, biscous coupling, active control friction clutch, and tosensin depending on the operation.
