Design and Maintenance Problems on Heavy-Duty Brakes 350120
THIS paper sets forth some of the many problems connected with the design and maintenance of heavy-duty brakes that urgently require solution.
Satisfactory brakes, on the heavier vehicles at least, should include the following features:
-
(1)
Brakes should be on all wheels, utilizing the entire weight of the vehicle.
-
(2)
They should be of internal construction with hinged shoes of some type.
-
(3)
Power of some sort should be used to obtain the pressures necessary to stop the vehicle with comfortable effort on the part of the operator.
-
(4)
Cast-iron drums, which give the best results so far as known at present.
-
(5)
The friction element should be some kind of so-called “fabricated” material, not so hard as the drum and in an easily replaceable form.
Detailed consideration of each of the foregoing five points is then presented, and a summary covering 10 desirable features for heavy-duty brakes is appended.
