Working principle for front absorber

See fig. 2, which is front absorber structure.
Through controlling organ and handlebar two front shock
absorbers (one pair) are connected with front assembling
tube of frame, which absorb shock relying on the liquid
damping which results from flexibility of absorber
spring, air compression and relative movement of inner
tube and outter tube.
The performance of front absorber is just like one kind of flexing movement,
that is to say, relative movement of innet tube (6) and outter tube (3). As a
result of stroke inner tube fixin in outter tube turns its position. Outter tube
is made up of upper oil pressure cavity and lower oil pressure cavity, piston
lever head with piston ring performs tightly with the top end of inner tube,
buffer bush is assembled in inner tube assy., which is to seal upper cavity.
Bufferprick is fixed in the bottom of outter tube, buffer prick is fixed in the
bottom of outter tube, which cum piston lever compose lower cavity. When
compression stroke is over, buffer prick and inner tube form oillock, which
prevent inner tube from stroking the bottom of outer tube, damping strength which
results from the two small damping holes in the processs of recover stroke.
Anti-dust ring assy. (10) fixed on the top of outer tube is to prevent drip,
dust etc. from going into tube, otherwise these dust may damage oil seal ring
assy. (12) or outer surface of inner tube. Oil seal assy. (12) fixed in the bottom
