differenciálmház

Differenciálmhöz refers to a differential housing, a component within a vehicle's drivetrain. Its primary function is to transmit power from the transmission to the drive wheels while allowing those wheels to rotate at different speeds. This is crucial for smooth turning. When a vehicle turns, the outer wheel travels a longer distance than the inner wheel. Without a differential, the wheels would be forced to rotate at the same speed, causing tire scrub, increased wear, and difficulty in steering. The differential achieves this by using a set of gears, typically bevel gears, that are arranged in a specific manner. These gears are housed within the differential casing, which is often referred to as the "differenciálmház" in Hungarian. The input shaft from the transmission connects to a pinion gear, which meshes with a ring gear attached to the differential case. Inside the case are spider gears mounted on a cross pin. These spider gears mesh with side gears, which are splined to the axle shafts leading to the drive wheels. When driving straight, the spider gears remain stationary relative to the differential case, and both side gears (and thus the wheels) rotate at the same speed. However, during a turn, the resistance of the outer wheel causes the spider gears to rotate on their pins, allowing the side gears to turn at different speeds. This mechanism ensures that both wheels continue to receive torque while accommodating the difference in rotational speed.
