Motorcycle and motorcycle automatic chain tensioner

Abstract

The invention discloses a motorcycle automatic chain tensioner. The motorcycle automatic chain tensioner includes a fixing part, an adjustment part, and a tensioning wheel. The fixing part includes a fixing frame and an anti-releasing sheet matching the fixing frame, wherein the anti-releasing sheet and the fixing frame are connected through a fastener, the fixing frame is L-shaped, an opening is formed in one top end at one side of the L-shaped structure, and a slide groove is formed outside the other side of the L-shaped structure. The adjustment part includes a first connection member and a second connection member; the first connection member is L-shaped, one side of the L-shaped structure matches the slide groove and is detachably and fixedly connected to the fixing frame, and the other side of the L-shaped structure is hinged to one end of the second connection member; the other end of the second connection member is detachably and fixedly connected to the tensioning wheel; and a tension spring is arranged between the first connection member and the second connection member. The motorcycle automatic chain tensioner can tighten a chain, and can avoid the problem of huge potential safety hazard to releasing and jamming of a loose chain during high speed travelling. The invention also discloses a motorcycle including the motorcycle automatic chain tensioner.
