Volvo — T-Ride

Description

This suspension is for both on-highway and off-highway applications. It features a parabolic tapered spring pack that is upside-down and mounted outside the frame rails.

There is a cushion that sits on each axle that is bolted to the end of each spring to absorb shock and vibration. Four lower torque rods control braking and acceleration forces. These suspensions are popular on waste haulers.

Tech Tips and Additional Resources

ATRO offers a full complement of load springs, V-rods, torque rods and torque rod bushings. Unlike the OE, ATRO also offers rebush kits for the V-rods. Polyurethane bushings (and kits) provide chemical resistance and better wear/abrasion resistance than rubber allowing for extended bushing life.

LP96-24657 – ATRO’s load spring with proprietary poly specifically formulated to absorb shock and dampen vibration rather than transferring it into the spring or frame
V-Rod Assemby – TR96-44004 (OE# 20367004) for most applications, and TR96-44829 (OE# 3172829), the original OE design. Both are pre-bushed with TH96-22200 at the apex and TS96-22600 (for V-rod TR96-44004) and TS96-22286 (for V-rod TR96-44829) end bushings.
Lower torque rods
- TR96-49046 – fixed length rod, 22 5/8” c-c with rotating pins, snap rings
- TR96-45568 – adjustable rod, rotating pins, snap rings
Replacement bushings for rebushing V-rods and lower torque rods
- ATRO’s TH96-22200 apex bushing - uses a low friction, high abrasion and wear resistant polyurethane. Fits ATRO V-rods TR96-44004 and TR96-44829.
- TS96-22600 – end bushing; fits ATRO V-rod TR96-44004 (and OE or others V-rods) and has split outer sleeve to conform to inconsistent eye sizes
- TS96-22286 – end bushing; fits ATRO V-rod TR96-44829 (and OE or others V-rods) and has split outer sleeve to conform to inconsistent eye sizes
- TS96-22700 – for all lower rod positions, fits both fixed and adjustable
- All ATRO torque rod bushings and V-rod end bushings for the T-Ride have rotating pins for easy installation and elimination of torsional stress, crimped outer sleeves, chemical bond to outer sleeves and snap rings
