3results about How to "Accurate braking" patented technology

The application discloses an AMT intermediate shaft brake control method. When the clutch is separated and the gear shifting is completed, the estimated gear-in speed difference at a certain set time after the current time is calculated after a period of time, and the current time is determined to be open brake valve for intermediate shaft brake or close brake valve for gear shifting according to the estimated gear-in speed difference. The application compares the estimated gear-in speed difference at the set time with the set speed threshold, opens or closes the valve in advance at the set time after the comparison, ensures that the valve action corresponds to the system response time, controls the continuous reduction of the speed, realizes the accurate brake, and avoids the problems of impact and tooth collision.

This utility model discloses a precast power wall end mold with a walking mechanism, relating to the field of precast power wall technology. It includes a mold body, a first mold support welded to the bottom of the mold body, an inclined support welded to the side of the mold body opposite to the casting side, a first roller and a second roller mounted on the first mold support, an independent roller mounted on the inclined support, and a braking device for braking the first roller. The lowest points of the wheel surfaces of the first roller and the independent roller are at the same height, used for rolling support on the top plane of the upper horizontal section of an I-beam track. The second roller is a conical wheel located below the first roller, used for rolling against the bottom inclined surface of the upper horizontal section of the I-beam track. When used as the end mold of a precast power wall casting equipment, this utility model's precast power wall end mold achieves more stable movement and excellent controllability.

This invention discloses a magnetic levitation circular conveying device and method, comprising: a mounting base, a controller, a circular magnetic levitation stator rail, a material conveying mechanism, a braking mechanism, a fixing frame, a linear motion module, and a vision recognition module; the controller is disposed on the front side of the mounting base; the circular magnetic levitation stator rail is mounted on the top of the mounting base; several material conveying mechanisms are spaced apart on the inner side of the circular magnetic levitation stator rail; the braking mechanism is disposed below the circular magnetic levitation stator rail; the fixing frame is mounted on the rear side of the mounting base; and the linear motion module is disposed on the top left side of the fixing frame along the front-rear direction. This magnetic levitation circular conveying device and method can achieve rapid braking during high-speed magnetic levitation circular conveying, shortening the braking distance, and can achieve precise braking during the conveying of heavier materials, making the material movement position more accurate.
