    摘要： A position limiting protection device for a test platform of a triaxial air-bearing turntable and its working method are provided. The triaxial air-bearing turntable is installed on a support frame and includes an air bearing support seat and an air bearing hemisphere. A test platform is placed on an adapter plate, which is placed above the air bearing hemisphere. The position limiting protection device includes three top rods and three annular parts, which are sequentially spaced to form a position limiting ring, the position limiting ring is located below the adapter plate and surrounds the air bearing hemisphere. The position limiting ring is spaced at a certain distance from the air bearing hemisphere, each annular part is fixed on a support frame, and the top rods are controlled to rise or fall to limit the movement of the test platform.

    摘要： A vehicle wheel service apparatus that includes: a frame; a plurality of working tools, connected to the frame and movable to perform operations for mounting and/or demounting the tyre relative to the wheel rim; a shaft driven by an actuator rotationally about a longitudinal axis and connectable to the rim; a measuring system for generating vibration signals representing vibrations of the shaft produced by wheel imbalances; a control unit, connected to the measuring system to receive the vibration signals; a support device, connected to the frame and movable between an activated position, where it encircles the shaft while still allowing it to rotate, and a deactivated position, where it is spaced from the shaft; a connector, movable between a working position, where it mechanically connects the measuring system to the frame, and a rest position, where the measuring system is mechanically disengaged from the frame.

    摘要： A system for converting an input oscillation having an input frequency into an output oscillation having an output frequency is disclosed. The system comprises: a controller configured for receiving the input oscillation and responsively generating a multi-component drive signal. A frequency of at least one component of the drive signal is other than two times the input frequency. In some embodiments, a frequency of another component of the drive signal equals about two times the output frequency. The system also comprises an oscillator for generating pump oscillations responsively to the drive signal and applying parametric excitation to the input oscillation at the pump oscillations.

    摘要： A self-releasing clamping tool that mounts a wheel onto a wheel balancer. The clamping tool has an adapter plate and a planetary gear assembly. The planetary gear assembly is an adjustable support system that maintains the wheel in a desired orientation while being balanced. The planetary gear assembly has a central gear and a collection of gear studs. The gear studs are support members that can be repositioned to correspond to the lug holes of the wheel. The central gear is rotatably mounted onto the adapter plate and the gear studs are detachably mounted onto the adapter plate. The central gear synchronizes the motion of the gear studs and the gear studs are easily detached from the adapter plate. Thus, preventing damage when dropped. A central hole traverses through the assembly and plate to enable the clamping tool to be attached to the wheel balancer.
