A foldable pedal apparatus for a vehicle includes a misoperation prevention pad, an accelerator pedal pad and a brake pedal pad. In a manual driving mode in which a driver directly drives, the accelerator pedal pad and the brake pedal pad protrude and are exposed toward the driver and then enter into a popped-up state so that operation of the pedal pads by the driver may be performed. In an autonomous driving situation, the accelerator pedal pad and the brake pedal pad are hidden and then enter into a hidden state in which exposure toward the driver is blocked so that the operation of the accelerator pedal pad and the brake pedal pad by the driver is unable to be performed. Furthermore, the misoperation prevention pad is provided between the accelerator pedal pad and the brake pedal pad.

The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece. The pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis. A bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction. Action of the prestressing element arranged between the bearing element and the pressure piece subjected the pressure piece to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. A sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack. In order to reduce the production outlay and/or allow a more compact design, on the side bearing against the sliding element, the pressure piece has a contour for compensating tolerances. The contour interacts with the sliding element.

The present disclosure relates to a transmission mechanism for a base station antenna, and a base station antenna including the transmission mechanism. The transmission mechanism includes a motor and at least one connecting rod, wherein a gear mechanism is provided on a first end of the connecting rod, and the motor drives the connecting rod to rotate via the gear mechanism; and wherein a worm gear unit is provided on a second end of the connecting rod opposite to the first end, and the worm gear unit is configured to drive a movable element of a phase shifter when the connecting rod rotates. The transmission mechanism according to the present disclosure can generate greater driving force through the worm gear unit, and has a shorter axial length and a smaller height, and thus is particularly suitable for a more compact and thinner 5G base station antenna.

The present application discloses a mechanism to adjust backlash in a rack and pinion powertrain assembly. The mechanism to adjust backlash includes a mounting frame having an opening defined therein to receive an operative end of a drive assembly, a shoulder fastener positioned through a first complementary set of holes at a first end of a mounting flange to movably couple the mounting flange to the mounting frame, the fastener being fastened in a manner such that the mounting flange and drive assembly have freedom to pivot about a longitudinal axis of the first complementary set of holes, and an adjustable length coupling device having a first end coupled mechanically to the mounting plate and a second end coupled mechanically to the mounting flange at a location substantially opposite the first end of the mounting flange.
