hi please send me the report about automatic differential unit locking system.

automatic differential unit locking system report pdf

ABSTRACT

When a working vehicle travels on a inclined ground or on an unlevelled ground, slipping causes a difference in revolution between right and left wheel impairing straight running of the vehicle.it is therefore conventional practice to equip a working vehicle such as a lawn mower or a garden tractor which needs to be run in a straight manner with a differential locking mechanism to forcibly stop the differential revolution of the wheels. If the differential lock remained on during all time then it may leave scratches on the ground. Hence an automatic differential locking system has to be designed to eliminate the above disadvantage. This system permits the differential to be locked only when the steering angle is below a predetermined value and release the lockup when the steering angle exceeds it.In this report we will be developing an automatic differential locking system for a vehicle with having a 4 wheel drive and with both front and rear wheels steerable selectively. An actuator will actuate the differential lock in response to the signal provided by the gate from the selector mechanisms and sensors.

OBJECTIVE

Primary objective of the project is to provide an automatic differential locking adapted to constantly maintain the differential lockup at times of parallel steering mode for improved running performance on an inclined ground or an unlevelled surface. Another objective of the invention is to provide a working vehicle equipped with above differential locking system to be capable of reliable straight running and excellent working performance. Also it aims in providing differential locking safety mechanism to release differential locking when an excessive load is encountered, thereby to save gears and other elements of differential from damage.

What you want about automatic differential unit locking system ?

An automatic differential locking system for a working vehicle having front and rear steerable wheels, including a selector for selecting a vehicle steering mode, an actuator for driving a differential lock mechanism and a door for sending a Control signal to the actuator in response to a signal received from the selector. The door is adapted to send a differential lock signal to the actuator upon receipt of a signal in parallel direction mode from the selector. In response to the differential lock signal, the actuator actuates the differential lock mechanism. Because differential wheel speeds are limited at times of parallel steering, the vehicle is able to accurately check and change the course without slipping.
