Air suspension systems

VDL Weweler has almost 45 years of experience in the development and production of air suspension systems. All VDL Weweler suspension systems are characterized by the parabolic trailing arm, which acts as an integrated roll stabilizer and as a guiding arm for the axle. The parabolic trailing arms are manufactured in-house, which offers the assurance of maximum quality and process control for this essential product and guarantees a long operational life. VDL Weweler is the only European spring manufacturer to develop and manufacture its own range of air suspension system solutions.

VDL Weweler’s modularly constructed air suspension systems are used by manufacturers of trailers, trucks and buses around the world. The modular design ensures compatibility regardless of axle type, size or manufacturer. This offers cost-effective logistical and technical advantages for the vehicle manufacturers. By using modular construction methods, Weweler can achieve efficient volume production while also maintaining the flexibility to meet the demands for small and medium volume specialized solutions and applications.

MBS-W

MBS^®-W75 is a compact designed lightweight standard range suitable for 9t. Ø127mm, []120 or thin wall Ø146mm axles and suitable for a wide range of trailers operating on highway conditions.
The MBS^®-W95 is a variation on the W75 range suitable for the more demanding conditions and can be used on a wide range of trailers operating on/off highway.
Both ranges make use of an axle seat that only requires welding on one side. The []120 clamping is bolted.
The axle seats are interchangeable between both ranges.
Both ranges are also available for 9t. Ø146mm groove axles in combination with the clamped Ø146 axle seat.
Full ride height range can be achieved by using various hanger brackets and pedestals.
Weight optimization is achieved by 2D rolling of the flexible high strength spring steel trailing arms.
The tapered design of the new hanger brackets offers great compatibility and allows for a more optimum frame width. The hanger brackets can be fitted with a patented casted bracing option, that ensures forces going straight into the chassis. This bracing is mandatory on the MBS^®-W95 range.
The shock absorbers are equipped with high temperature Viton^® seals and designed to be the stroke limiter of the suspension system.
Furthermore the range offers easy alignment with re-alignment free bushing, fully interchangeable air springs and low & easy maintenance.

MBS-HD

The HD 9t. - 13t. is a well proven, robust single and twin leaf air suspension range, that can best be described as an all-round solution for many trailer types and suitable for most on and off road conditions worldwide.
This air suspension range is equipped with 2D rolled flexible high strength spring steel trailing arms and can be fitted to all standard trailer axle sizes (Ø127mm, Ø146mm, []120mm and []150mm).
The modularity of the complete range ensures the different components are reduced to a minimum and many components are fully interchangeable throughout the whole range.
The closed reinforced hanger brackets can be fitted with a patented casted bracing option, that ensures forces going straight into the chassis.
The HTLT shock absorbers are equipped with high/low temperature Viton^® seals and designed to be the stroke limiter of the suspension system.
Furthermore the range offers easy alignment with re-alignment free bushing, a higher overload threshold and low & easy maintenance.

MBS-HD Special

The HD Special is a specific, well proven, robust 9/10t. single leaf air suspension range within the HD family.
This suspension range is predominantly used in underslung configuration on 17.5 or 19.5 inch axles that require disc brakes and run at low ride height. The longer front-end of the spring steel trailing arms allows for more up and down axle travel, whilst still maintaining enough clearance for the brake booster.
The air suspension systems are equipped with flexible high strength spring steel trailing arms and can be fitted to all standard trailer axle sizes (Ø127mm, Ø146mm, []120mm and []150mm).
The closed reinforced hanger brackets can be fitted with a patented casted bracing option, that ensures forces going straight into the chassis.
The HTLT shock absorbers are equipped with high/low temperature Viton^® seals and designed to be the stroke limiter of the suspension system.
Used in an overslung configuration, these air suspension systems can be used for tipper applications, with the option of long- or short-stroke air springs.
Furthermore the suspension offers easy alignment with re-alignment free bushing and low & easy maintenance.

Specifications

Maximum axle load: 9t / 10t
Single leaf trailing arms: 100x54mm / 100x59mm
Trailing arm dimensions: L1 = 565mm & 620mm & 690mm / L2 = 315mm & 380mm & 400mm

MBS-GF

With numerous patented innovations, the MBS^®-GF is a revolutionary light weight air suspension system, suitable for 9t. thin wall Ø146mm grooved axles.
Sold in Europe through Valx, this multi-purpose air suspension can be used on a wide range of standard trailers operating on highway conditions.
The air suspension is clamped around the axle using three bolts and is held in position by an ingenious groove in the axle beam, offering unique modularity in spring track.
A first in trailing arm suspension design, the unique forged flexible trailing arm eliminates the need for U-bolts and U-bolt plates. The tapered trailing arm with its wider clamping area and small diameter maintenance-free bushing provides unequalled roll stiffness while putting less stress on the axle, therefore maximizing the service life.
By releasing a single bolt, both tail ends can be given offsets of 0, 25, 50, 65, and 90mm in either direction, eliminating the need for a left and right version.
The HTLT shock absorbers are equipped with high/low temperature Viton^® seals and designed to be the stroke limiter.
