A swing type wheel locking device includes a wheel axle and a pivoting part. A wheel body has an outer wheel face and an axle hole fitted on the periphery of the wheel axle at a position close to the axle end part. A plurality of positioning concave parts are arrayed in a circle on the outer wheel surface. A swing type wheel locking component is pivoted on the wheel axle and has a pivoting end and a swing section. The pivoting end is pivoted on the pivoting part, so that the swing section can be forced to swing, and by choosing different swing angles, it can be shifted between a locked position and released position. When a clamping convex part of the swing section is at a locked position, it is locked right inside the corresponding positioning concave part. Thus, the wheel body is locked against rotation.

An electromechanical brake system includes: a pair of pad plates to which a brake pad is attached, respectively, to press a disc that rotates with a wheel; a carrier on which the pair of pad plates are installed; a caliper housing slidably installed on the carrier; a piston movably installed in forward and backward direction inside the caliper housing; a power transfer part configured to press the pair of pad plates onto the disc by moving the piston; a brake actuator including a drive motor configured to provide a rotational force of the drive motor to the piston, and a reduction gear part configured to decelerate the rotational force of the drive motor and transmit the decelerated rotational force to the power transfer part; a parking actuator connected to the brake actuator to maintain a parking braking state of a vehicle; a force sensor configured to detect a clamping force due to a contact between the disc and the brake pad; and a controller configured to control the brake actuator and the parking actuator, wherein the controller is configured to control the parking actuator based on the clamping force detected through the force sensor.

The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.

A multi-pawl park lock includes a gear wheel, an actuation ring, a first pawl, a second pawl, and first and second strut rods. The first pawl includes a first tooth and the second pawl includes a second tooth. The strut rods connect the actuation ring to respective pawls. The actuation ring is arranged to rotate in a first rotational direction to rotate the first pawl about a first pawl axis and engage the first tooth with the gear wheel, and rotate the second pawl about a second pawl axis and engage the second tooth with the gear wheel, preventing rotation of the gear wheel. The actuation ring is also arranged to rotate in a second rotational direction, opposite the first rotational direction, to rotate the first pawl and disengage the first tooth, and rotate the second pawl and disengage the second tooth, permitting rotation of the gear wheel.

A drive lock for locking a roller chain or belt drive system to stop rotation of both the driver, such as a motor, and driven assembly, such as a wheel. By stopping rotation, the drive lock permits maintenance to be performed while the driver and driven system remain stationary, reducing the risk of damage to the drive system. The drive lock utilizes torque generated by pulley rotation to positively lock the roller chain/belt and pulley thereby preventing rotation in the direction the torque is applied.

In a vehicle parking lock mechanism, a parking pawl mechanically hinders rotation of the parking gear by being engaged with the parking gear. A lock member is moved to the lock position to establish a parking lock state in which the parking pawl hinders rotation of the parking gear. The support member includes a guide portion configured to guide movement of the lock member between the lock position and the unlock position while restricting the lock member from displacing in a direction away from the parking pawl. The stopper is rotatably mounted to either one member of the lock member or the support member, changes a posture in accordance with relative movement between the lock member and the support member, and protrudes toward the other member side of the lock member such that the stopper establishes a protruding posture in the parking lock state.

A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a ballast coupled to the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein the vehicle is provided with an mechanism for locking and unlocking the brake system.

A commercial vehicle with at least one driven axle, at least one service brake, at least one propulsion engine, and wheels characterized in that the parking brake function of the vehicle is solved by a bistable locking means acting on both wheels. At least one multi-speed gearbox is provided to concurrently activate a first gear stage and a second gear stage having different ratios.

A parking lock has a parking lock housing (20), a locking pawl (12) which has a ratchet (16) that can be locked in a parking lock wheel (56) and a pawl profile (44) arranged on the rear side of the ratchet (16), an actuating unit (24) which acts upon the pawl profile (44) when the parking lock (10) is engaged and thereby rotates the locking pawl (12) about a rotational axis (14) relative to the parking lock housing (20), and a supporting element (18), on which the actuating unit (24) is supported in the engaged state (P) and in the disengaged state (nP) of the parking lock (10) at different positions. The supporting element (18) is connected to the parking lock housing (20) so as to have play.
