Coordination of Electric with Other Braking Systems 550238
HOW electric-actuated trailer brakes synchronized with the air, hydraulic, or vacuum are braking system as used on tractors is described here.
Brake balance between the electric and other systems used involves balance of brake buildup rime. This is done by having the two types of brakes build up simultaneously for their respective axle loads and tire sizes. A load control consisting of a variable rheostat does this job for the electric brakes. It is also used for balancing the electric brakes with the tractor brake system.
The speed and versatility of electricity as used for trailer brakes make possible synchronized braking of combination vehicles without sacrifice of tractor brake speed — all brakes work simultaneously, resulting in shorter stops and less danger of jaakknifing.
Other important safety features of the electric brake include: (1) They furnish an independent braking system for the trailer. (2) They are operated by a constant source of power.
