Friction Snubbers
|
| |
|
|
| |
|
Enidine Friction Snubbers are used
primarily to control vertical and lateral motion on
subway passenger cars andlocomotives, guarding against
lading damage and providing increased ride quality.
These mechanical type
shock absorbers are ruggedly constructed, assuring trouble-free
service under varying temperatures and environmental
conditions.

| Construction
and Operation |
|
The friction snubber is comprised
of a barrel containing three segmented shoes faced with
specially formulated long-wearing, molded brake lining
material, attached by a special bonding process. The
constant pressure of a pre-compressed coil spring forces
the shoes outward against the barrel. Uniform friction
resistance is provided during operation through a combination
of material and finish in the lining and barrel. Mountings
are designed to provide “universal joint”
action to accommodate any change in the angularity of
the snubber caused by relative movements between the
mounting members

Outstanding Features
|
|
•
|
Three Segmented Shoes are forced
against the barrel by spring pressure exerted
equally on opposing wedge surfaces, providing
consistent damping.
|
| • |
Units Maintain a Constant damping
force unlike hydraulic shocks which are velocity
sensitive.
|
| • |
Mountings Provide “Universal
Joint” Action to reduce relative motion and
eliminate backlash in the system.
|
| • |
Self-Compensating Design for
service wear. The free wedge ring allows automatic
take-up as shoe lining wears.
|
| • |
Wide Temperature Operating Range
from -60º to 400º F.
|
| • |
Standard Production Units can
be provided with
frictional resistance forces from 130 to 3,300lbs.
|
| • |
Vibratech Friction Snubbers can be applied to
springs of any size to meet any damping requirement.
