摘要： A self-balancing Two-Rotation Driving Mechanism (TRDM) uses parallelogram and has low weight, high load, high accuracy, quick response and good adaptation with multi equipment. A longitudinal rotation motor assembly is constrained fully with a base assembly and drives a longitudinal rotation assembly through connecting rod parallelogram. The lateral rotation motor assembly is assembled in the hub of a longitudinal rotation assembly and rotates an equipment clamping assembly in a lateral direction. Generally, the TRDM can drive equipment clamping assembly in two rotations, with longitudinal rotation in the range of ±45° and lateral rotation in range of ±20°. A rotation limitation is reached when limitation shafts touch the end of respective grooves.

摘要： The ANGULAR ROTATION LOCKING MECHANISM (ARLM) is used on cargo transport vehicles such as trucks and ships. The structure has a large load capacity, the ability to open and close easily, flexibly, but ensures the ability to lock the brake during the transport of the vehicle, in all weather conditions. Because of a purely mechanical structure, the maintenance and repair process is simple. The main point of the design is the self-positioning between the front pedestal shaft and the locking blade during operation.
