[1]Tire
The tire of motorcycle is the important component of riding system.Its function is to touch road surface
directly,support the weight of whole motorcycle,reduce strike and shake during running with its elasticity,
ensure balanced motorcycle running and avoid sliding.Tire consists of outer tire,inner tire and gasket.
Outer Tire
Outer tire consists of tire surface,tire body,gasket and tire ring.The surface of outer tire directly touches
road surface.There are different thread on tire surface,which helps motorcycle avoid sliding on different
road.The tire body has a certain intensity,but in order to emit heat,it had better not be too thick.The tire ring
is packed by the edge of curtain and steel ring,which makes outer tire fix on the rim.If the perimeter of tire
ring is too short,which will make the disassembly of outer tire more difficult and if the perimeter is too long,
which will make outer tire spring out.The curtain tier is the framework of outer tire.But the curtain tier of
outer tire crosses with the transect of tire,which makes an angle.But the curtain tier of meridian tire arrays
as the direction of earth meridian.The meridian tire has the good characters of reducing power consumption,
fuel consumption and prolonging service lifetime.
Inner tire and Gasket
Inner tire is made of rubber.It is a circle.There is a valve on it,which can adjust the pressure of inner
tire.The main requirement of inner tire is seal.The pressure of inner tire is the main reason of influencing
the usage of wheel and tire.The gasket is a round rubber cincture,which separates inner tire and rim,
protects the seal of inner tire and prevents the break caused by the spiculate thing.
[2]Rim
Rim is the framework for supporting and fixing the tire.The rim of this motorcycle has two types, die-
casting rim and spoked rim.The former is made from aluminum alloy,which integrates the rim and hub by
casting and then machining.This kind of rim has high intensity,simple arts and crafts,convenient
installation,but poor elasticity and cannot be adjusted.If the rim is distorted or damaged,you should
replace the whole rim.The spoked rim is made from steel strip.In the wheel rim,there is a lot of hole seats,
in which a spoke and spoke nut are installed.The other end of spoke connects the wheel hub.Therefore,
the spoked rim has a good shock resistance,adjustable characteristic and convienent maintenance.In this
part, it mainly discusses the die-casting rim.
[3]Wheel Hub
The wheel hub of motorcycle is divided into front hub and rear hub.The structure of front hub and rear hub is very
familiar.The rear wheel is drive wheel,so there is power transmission device installed on rear hub.There are bearing,
bearing gasket,oil seal and axle installed in the front and rear hub,which is good for the operation of wheel hub.
Section 10 Wheel
1 The Structure and Working Principle of Wheel
2 Disassembly and Maintenance of Wheel
Front/rear wheel is the running component of motorcycle.It supports the weight of whole motorcycle
and ensures a friction made by wheel and road to make wheel avoid sliding.Wheel can reduce and absorb
the strike and shake caused by the road.The front wheel cooperates with operating part,which fixes on the
direction of running.The rear wheel is transferred power by engine,which drives motorcycle to run.Wheel
mainly consists of outer tire,inner tire,aluminium tire,tire hub,bearing,bush,oil seal and axle.
[1]Check whether tire pressure is within the normal
scale.Clean out the deposit of outer tire thread.Avoid
inner and outer tire damaged.
Check the abrasion of outer tire.Replace it if it
exceeds the limit value:2.00mm.
Check front
wheel.
