Maybach repellent claw

Maybach deflector claws are shift elements in automatic gearboxes. They transmit the torque on the basis of claw clutches and are mainly used in Mekydro gears .

The first use of a Maybach deflector claw from the literature can be found in 1928 in the construction of the high-speed transmission in the Maybach W 5 SG automobile . The two-speed planetary gearbox was followed by an overdrive gearbox that was operated by lever movement and shifted via the Maybach deflector claw without actuating the clutch.

The construction of the Maybach rejection claw is shown on the internet sketch; In the first few applications, the claw movement still had to be operated by hand. Before operating the overdrive lever, the power transmission had to be interrupted so that the claw movement was possible. The power transmission of one gear was separated by the lever movement. When the connecting claws of the high gear met each other, their claws moved in the direction of the rising end faces of the counter claws, the coupling halves were then rejected. Only by accelerating again could the claws snap into the transmission notches and the overdrive was switched on. This switching process was not quiet, but against the subsequent drop in engine speed at higher speeds, this noise could be tolerated.

Several Maybach deflector claws shift Mekydro gears . Shifting is carried out with oil pressure and the automatic engagement of the claws is controlled by a release converter . The DB class 218 , with an engine output of around 2,000 kW , shows that the connections can transmit great power .
