QA1 Custom Product Examples:

 

Monorail/People Mover Dampers

QA1 worked with vehicle manufacturers to develop dampers to control sway and rocking of the vehicle cars in monorails/people movers. The dampers operate in all types of weather conditions all around the world.

 

NASA Space Exploration Vehicle

QA1 worked with NASA to develop dampers for their new space rover vehicle. The dampers are hidden under the white socks on the suspension of the vehicle. The space rover vehicle uses twelve dampers, two per axle.

 

Modular Front Suspension and Drive Assembly

This assembly was specifically designed by QA1 for the fast growing neighborhood electric vehicle (NEV) market. The components that QA1 designed, manufactured or sourced in this sub-assembly include: welded tubular sub frame, tubular suspension arms, ball joints, suspension bushings, knuckle castings, special wheel bearings and seals, wheel hubs, stainless brake disk, forged aluminum brake calipers and CV drive shafts.

 

Steering and Front Drive Assembly

This off-road design by QA1 has been used by a major all-terrain vehicle manufacturer. The design and reliability requirements of this type of assembly approach that of military specifications. The assembly is subjected to the most severe conditions of heat, cold, water submersion, and obstacle impact-- and it requires little or no maintenance. QA1 is very familiar with these and other off-road components, and can similarly design for your existing application, or assist from the design stage, to meet a broad range of customer needs.
