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.
