The utility model relates to a silencer and a motorcycle, which comprises a front silencer section, a rear silencer section and a connecting component for connecting the front silencer section and the rear silencer section, the connecting component comprises a front connector fixedly connected with the front section of the silencer, a rear connector fixedly connected with the rear section of the silencer, a graphite ring and a hoop, the front joint is an inner pipe joint, the outer surface of the root part of the inner pipe joint is provided with a limiting ring, the graphite ring is close to one side of the surface of the front joint close to the end head and is attached to the limiting ring, the rear joint is an outer pipe joint provided with a plurality of deformation joints, and the end of the rear joint is lapped on the surface of the limit ring, the hoop is tightly held on the outer surface of the rear joint, the hoop is partially overlapped with the axial arrangement position of the limit ring, the limit ring has a certain width, and the limit ring is ensured to be in surface contact with the rear joint and the hoop, so that the rear joint is more stable.

Further, the thickness of spacing ring is less than the thickness of graphite ring, and the difference in height between concrete graphite ring and the spacing ring is for how much compile and decide according to the fastening torsion of corresponding motorcycle type, guarantees that the staple bolt compresses tightly the back, and the graphite ring possesses certain compression volume, guarantees the leakproofness, and follow-up is the spacing ring atress, guarantees that the graphite ring is not broken by the pressure, dismantles the assembly back graphite ring many times and still can have good gas tightness, improves the rate of repeated use.

Further, the movement joint is bar opening seam, and the extending direction of movement joint is unanimous with the extending direction of rear connector, and the setting of movement joint can guarantee that rear connector can reduce the internal diameter size symmetrically under the effect of staple bolt, reaches the laminating and the face contact that reach with the spacing ring is good, makes the connection between the front and back connector more firm.

A motorcycle adopts foretell silencer.

The utility model has the beneficial effects that: according to the silencer and the motorcycle disclosed by the utility model, the contact between the front joint and the rear joint and the hoop is improved by adding the limiting ring, a stable space which is favorable for sealing is provided for the graphite ring, the problems that the front section and the rear section in the original sectional silencer fixed connection structure are not tightly held and air leakage is easy to generate are solved, the contact between the hoop and the rear joint as well as the limiting ring is converted into surface contact, the silencer and the motorcycle are more stable, and good air tightness can be achieved after the graphite ring is disassembled and assembled for many times on the premise of not increasing the assembly difficulty.
