Trailer Modules

Nearly 20 Years & Millions Of Miles Of On & Off Road Performance

Axleless® Modules are used by specialty manufacturers and up-fitters for use in low floor trailers and are available in 14,000lb to 42,000lb capacities. Axleless® Modules are supplied as complete structural units, including a fully integrated low floor suspension system. Manufacturers and up-fitters install standard “fore” and “aft” sections of the trailer frame to the Axleless® module to form a complete, unitized trailer frame structure. Dallas Smith Corp. provides manufacturers and up-fitters with complete design and engineering services to support the necessary trailer frame/Axleless® module fabrication interfaces.

• Super single wheels/tires
• Electric, hydraulic, & air brake options
• Up to 30% reduction in suspension weight
• Easy to set and maintain true, accurate wheel alignment… camber & toe

Module Specifications

Improved Vehicle Productivity & Profitability

• Axleless® “Low Floor” vehicles provide up to 30% more “payload” carrying capacity than conventional high floor vehicles…and Axleless® suspensions typically weigh 20% to 30% less than conventional solid thru-axle suspensions.
• Less on-the-job injuries when workers can easily step-in and step-out of trailers and trucks…Axleless® provides vehicle floor heights as low as 8 inches.

Improved Vehicle Ride

• Axleless® is a “true” independent suspension…one wheel’s motion does not affect the vehicle’s opposite wheel. Less shock and vibration over rough roads means less shock and vibration for the payload and driver.
• Axleless® independent suspension with lower unsprung weight helps eliminate “axle hop” and tire “bounce” and their effects on the driver and payload.
• Axleless® low floor suspensions provide much more wheel travel compared to trailers having multiple solid axles with smaller wheels and tires. Axleless® can ride over undulating surfaces without contacting the bump stops and “bottoming out”.
• The soft ride is enhanced by the wider spring spacing which allows good vehicle roll stiffness even with softer springs.
• Axleless® air ride suspensions provide the most comfortable and cushioned ride available for a driver and his cargo.

Improved Vehicle Stability & Safety

• Axleless® low floor suspensions reduce the payload height (lower center of gravity). This greatly increases roll stability.
• Axleless® Wide-Trac™ suspension’s wider track width allows more lateral acceleration without rollover.
• Wider spacing between suspension bump-stops limits body roll during emergency maneuvers, which also increases roll stability.

Improved Vehicle Handling

• Axleless® independent suspension with less “unsprung weight” provides better contact with the road at all times and better traction even under rough road conditions.
• Less axle hop and no dynamic interaction between wheels on opposite sides enhance road-holding…this also results in shorter braking distances on rough roads.
• Less body roll when cornering allows more responsive direction transitions, such as S-curve maneuvers.
• Better traction under emergency situations keeps the vehicle on the road.
