20210396311 | Parking lock actuator for integration in a vehicle transmission - A parking lock actuator includes a blocking cam, an actuating device, an energy store, a blocking drive, and an intermediate element. The blocking cam is arranged for positive engagement with a tooth gap of a parking lock gear and the actuating device is for transferring an actuating force to the blocking cam. The energy store is for transferring the actuating force from the actuating device to the blocking cam, the blocking drive is for displacing the actuating device, and the intermediate element is freely displaceable relative to the blocking drive over a predetermined intermediate path for displacing the actuating device. The blocking cam is arranged to positively engage the tooth gap to block rotational movement of the parking lock gear when the actuating device is in a blocked position, and the parking lock gear is rotatable when the actuating device is in an open position. | 2021-12-23 |
20210396312 | PARKING LOCK DEVICE - A parking lock device for a transmission of a vehicle. The device comprising a wheel, a pawl for locking the wheel against rotation and an actuator unit arranged for movement of the pawl relative to the wheel. The pawl has a locked position where the pawl and the wheel are engaged and an unlocked position where the pawl and the wheel are disengaged. The pawl and the actuator unit are mechanically coupled to each other by a pin and slot mechanism having a guide slot and a guide pin received by the guide slot. | 2021-12-23 |
20210396313 | PISTON COMPRESSION RINGS OF COPPER ALLOYS - A piston ring is made from a copper-nickel-silicon-chromium alloy. This material permits the top compression ring of a piston to be moved closer to the piston crown, reducing crevice volume and reducing the tendency for pre-Ignition. Ignition timing advance can be realized by installing the rings and letting the ECU advance the timing as the sensors allow, increasing efficiency. Also, shorter pistons and longer connecting rods are possible. The shorter pistons reduces the reciprocated mass in the engine and the longer connecting rods reduce the frictional loss caused by radial forces pushing the piston against the liner. Both reducing volume and tendency for pre-ignition increase engine efficiency. | 2021-12-23 |
