HAHS-1 BOGIES (introduction)• Modification over high adhesion bogies & designed forhigh horse power ALCO locomotives to achieve highertractive effort at start.• 3-axle type bolster less bogie with two stage suspension,floating pivot and uni-directional arrangement of axlehung, nose suspended traction motors.• The locomotive body weight is supported on bogie framethrough four rubber side-bearers directly mounted onbogie side beams.• Side-bearers adjacent to centre pivot take 60% weight whilethe other two take 40%.• The bogie frame in turn is supported on axles throughhelical coil springs mounted on wing type axle boxes.
HAHS-1 vs High Adhesion• HAHS-I• High adhesion withhigh tractive effort.• Primary suspensionsprings arranged onwinged type axle boxes.• Vertical shock absorbersfitted with axle box.• Load distribution notequal• Two bearers adjacent tocentre pivot @ 30%• Two other bearers @ 20%Bogie.• High Adhesion• Only high adhesion.• Primary suspensionsprings arranged onbeams.• Vertical shock absorbersfitted on beams.• Equal Load distributionby all four side bearers@ 25%.
