Triumph TR2 - Rear Shock Absorber

ROAD SPRINGS AND SHOCK ABSORBERS
volume equal to the displacement of the
piston rod (D) passes through the ports
(E)
in the piston rod guide (F), down the anti-
foam
tube (G) and into the reservoir (H) by
way of the rebound valve (RV).
On the rebound stroke, however, the piston
valve
(Pv) closes and oil passes through the
ports
(E) in the piston rod guide (F), down
the anti-foam tube
(G), opens the rebound
valve (RV) against the spnng load and passes
into the reservoir (H). At the same time the
foot valve plate (Fv) lifts and oil is recuper-
ated to the lower part
of the cylinder (B).
General slow speed damping is accomplished
by bleed orifices
bult into the valve
mechanism.
The maximum load of compression (bump
is 200 lbs. and on extension (rebound
500 lbs.

REAR SHOCK ABSORBER
I. DESCRIPTION (Fig. 5)
The shock absorber body is attached to the
brackets welded to the upper sides of the
chassis
flame and linked to the rear axle by
an arm, splined to the shock absorber
spindle, and a connecting
link to a plate
assembly mounted on the underside of the
road spring.
The body
has two equal sized cylinders
accommodating steel pistons which are recip-
ricated through short connecting rods and
are coupled to the
crank plate which is
attached to the spindle.
When the axle moves relative to the
car
(this movement is allowed b
the road
spring) the
arm is moved up or 1 own, and as
it is splined to a spindle, the latter rotates.
The spindle is a splined fit in the
crank
plate, this plate being coupled by means of
connecting rods to the pistons, in which
are situated
lightly loaded recuperating
valves. The pressure is built up in one
cylinder or the other and since the cylinders
are connected by
ports in the body to the
valve chamber, this pressure is dependent
on the valve setting.
