FRONT AXLE - OPERATING PRINCIPLE

2.2 DIFFERENTIAL SYSTEM

The differential pinion idles or rotates simultaneously as well as rotates both differential side gears at the same or different speed depending on the condition of road or the tractor's moving direction. It is the main principle of the differential system.

For detail of differential system, please refer to 2.2 “Principal of differential system” in chapter “Rear Axle”.

2.3 LOAD TRANSFER

When the steering system is operated, the front axle case (1) rotates around the pivot shaft (A) of the bevel gearcase (2).

The longitudinal load transferred to the front axle case (1) from the front wheels is transferred to the bevel gearcase (2) through the ball bearing (3).

Also, the lateral load applied to the front axle case is transferred to the bevel case through the ball bearing (4) which is installed on the bevel gearcase. In other words, the longitudinal load is supported by one point, the lower ball bearing, and the lateral load is supported by one point, the upper ball bearing (5).
