Parking lock for an automatic transmission and method for operating the parking lock
In a parking lock for an automatic transmission, an electrical parking lock actuator has an electric motor, a spur gear stage driveable by the electric motor, and a worm gear stage driveable by the spur gear stage. A worm shaft of the worm gear stage is connected rotationally conjointly to an output gear of the spur gear stage, and a worm gear of the worm gear stage is connected rotationally conjointly to a transmission-side parking lock shaft. The worm shaft is fixed in an axially displaceable manner in the output gear. A stop limits the pivoting movement of the worm gear when a parking lock position of the parking lock shaft is reached. A spring braces the worm shaft in an axial direction of the worm shaft against a holding mechanism which is situated in a stop position, in which the holding mechanism is fixed by an electrically energized electromagnet.
VEHICLE SYSTEM AND METHOD FOR REMOTE START OPERATION
A vehicle system and method for remote start operation in the vehicle system are provided. The method includes responsive to receiving a remote start request and while the vehicle is stationary, automatically engaging a wheel-arresting device coupled to a wheel in the vehicle. The method also includes when an electronically actuated clutch is automatically disengaged and subsequent to the automatic engagement of the wheel-arresting device, implementing remote start operation in an engine, where the wheel-arresting device is distinct from a secondary vehicle brake.
Parking lock device for vehicle
A parking lock device for a vehicle includes a parking gear, a locking pawl, and a cam mechanism. The parking gear includes a parking lock gear that includes outer teeth that engage with a locking lug and rotates about a rotation axis, and a parking lock gear base fixed to an output shaft and allowed to rotate relative to the parking lock gear about the rotation axis. A space is provided between the parking lock gear and the parking lock gear base, such that the space expands and contracts in a circumferential direction according to relative rotation of the parking lock gear and the parking lock gear base, and an elastic body is provided in the space in a pre-compressed state.
Gear shifting apparatus for multi-speed transmission for electric vehicles
A gear shifting apparatus for a multi-speed transmission includes: a shifting unit controlling gear shifting by an actuator, and a parking unit controlling parking by the actuator. In particular, the actuator includes a control motor driving a driven gear through a drive gear externally gear-meshed with the driven gear, and the shifting and parking units are operated by a force received from a cam block fixed to the driven gear. The shifting unit includes a fork slider slidably mounted on a fork rail, a shift fork integrally formed with the fork slider, and a cam contact pin integrally formed with the fork slider and contacting the cam block.
SWITCHABLE I-BRAKE FOR HYBRID TRANSMISSION
A clutch assembly comprises an actuation assembly, an outer ring, and an inner ring disposed radially inward of the outer ring and rotatable about an axis in first and second rotational directions. A first and second strut are rotatably disposed within first and second pockets of the outer ring and configured to be rotated by the actuation assembly. A first pawl and a second pawl are rotatably disposed within a third pocket and a fourth pocket, respectively. For a transition mode, the actuation assembly is configured to rotate the first strut within the first pocket such that rotation of the first strut in the first rotational direction urges the first pawl radially inward into partial engagement with teeth disposed on an outer surface of the inner ring, the second pawl remains free of contact with the inner ring and the inner ring rotates in the first rotational direction.
Vehicle parking apparatus
A vehicle parking apparatus displaced across first and second cases joined together through joined surfaces. The vehicle parking apparatus includes a rotation member supported rotatably at the first case to rotate in accordance with parking activation command and parking release command, a parking rod extended from the first case to the second case and including a base portion supported rotatably at the rotation member to move to first direction and second direction by rotation of the rotation member, a parking pole supported swingably at the second case and brought into contact with a top portion of the parking rod to engage with and disengage from a parking gear in accordance with movement of the parking rod in the first direction and the second direction, and a plate shaped stay fixed to the first case and including a notch into which the parking rod is inserted.
ELECTRIFIED VEHICLE WITH ORIENTED PARKING MECHANISM
An electrified vehicle includes a multi-phase electric machine having a rotor with a number of magnetic pole pairs and secured for rotation with an output shaft. A parking gear secured for rotation with the output shaft has external teeth configured to selectively engage a parking pawl. The parking gear, the rotor, and the output shaft include complementary angular alignment features to angularly orient the parking gear relative to the rotor in an angular position offset by an index angle from one of the magnetic poles of the rotor such that occurrences of the parking pawl being engaged with the parking gear during dead time periods of an inverter powering the electric machine are reduced or eliminated.
Electric Travelling Vehicle and Grass Mower
An electric travelling vehicle including: a motor controller configured to control an electric motor based on displacement of a steering operation part to a forward travel position, a neutral position, and a rearward travel position, a brake controller configured to bring an electromagnetic power-off brake into a released state or a braking state; and a travel state detector configured to detect a travelling state that is accompanied with the released state, a stopped state that is accompanied with the braking state, and a transit stopped state that is accompanied with the braking state.
Parking lock for a motor vehicle
A parking lock (1) for a motor vehicle, wherein the parking lock (1) has a housing (21), a locking pawl (4) which is arranged such that it can be pivoted about a rotational axis (a) and has a pawl tooth (5) which is configured for engaging in a positively locking manner into a parking lock gear, an actuator (6) for actuating the locking pawl (4), with the result that it can be brought reversibly into engagement with the parking lock gear by way of the pawl tooth (5) of the locking pawl (4), and a movable transmission element which transmits the movement of the actuator (6) to the locking pawl (4). The parking lock (1) has a damping mechanism for the locking pawl or for the movable transmission element.
Vehicle drive apparatus
In a vehicle drive apparatus, a drive gear which engages with a gear provided on the counter shaft is provided on the input shaft relatively rotatably to the input shaft, and the vehicle drive apparatus comprises a switching mechanism including an actuator and a connection/disconnection sleeve which is driven by the actuator in a direction of the first rotation axis and which selectively switches between a first state in which the drive gear is connected to the input shaft and disconnected from a non-rotating member and a second state in which the drive gear is disconnected from the input shaft and connected to the non-rotating member.
