This invention relates to the field of motorcycle technology and discloses a motorcycle reach angle adjustment mechanism. The frame has detachable flange seats at both the top and bottom. A bearing ring is embedded inside the flange seat, and an oil seal ring is embedded between the bottom of the bearing ring and the flange seat. The frame bore is coaxial (coaxial with the outer circle of the flange seat). The inner circle of the flange (bearing press-fit surface) and the outer circle of the flange are machined to form an angle. Users can remove the upper and lower flange seats, rotate them 180°, and reassemble them into the frame as needed to adjust the reach angle. During use, the reach angle of the entire motorcycle can be adjusted according to the vehicle's usage requirements. This satisfies both the handling sensitivity required for extreme track riding and the high-speed stability needed for long-distance motorcycle touring, providing different driving experiences and enjoyment with a single motorcycle.

The utility model relates to the technical field of textile machinery manufacturing, in particular to an active rapier opening device of a rapier loom. The mobile cam mechanism includes a mobile cam and a roller follower assembly. The swing mechanism is driven by the beating-up swing shaft to slightly deflect. And the moving cam performs reciprocating linear displacement motion under the action of the traction force from the swinging mechanism. The roller driven assembly is used as an assembly foundation of the mounting seat. The rapier opening block is used for pressing the rapier receiving head of the rapier so that the rapier receiving head can release yarn and is fixed to the installation base. In the process that the roller driven assembly is controlled by the cam profile of the movable cam to execute reciprocating type linear displacement motion, the mounting base can drive the rapier opening block to be close to / away from the rapier receiving head of the rapier. Thus, on one hand, the displacement precision of the rapier opening block is guaranteed, and then the reliability and accuracy of implementation of the follow-up rapier opening action process are improved; and on the other hand, the service life of the rapier receiving head and the service life of the rapier opening block are greatly prolonged.

The invention discloses an intelligent empennage control system and method based on multi-sensor fusion, and the method comprises the steps: employing an online deduced self-induced aerodynamic load as a known feedforward input, stripping the unsteady interference caused by the action of an empennage from original data through a decoupling type extended Kalman filtering algorithm, thereby obtaining a real net vehicle body posture, and achieving the control of the empennage. On the basis, accurate and coordinated control of the downforce is realized through a multi-target optimization decision based on a net state. In this way, in a high-performance driving scene, it can be ensured that the vehicle obtains excellent high-speed stability, meanwhile, ideal front and rear axle load distribution and steering responsiveness are maintained, and the dynamic control limit and driving safety of the vehicle are comprehensively improved.
