Embodiment Construction

[0023] First refer to figure 1 , the tractor frame 1 has front and rear drive axles 2 and 3, which are supported on the frame 1 in a known manner by paired air suspension airbags 4 and 5, 6 and 7, 8 and 9, and 10 and 11 On , pairs of bladders are positioned on each side of shafts 2 and 3 as shown.

[0024] The bladders 4 and 8, 5 and 9, 6 and 10, and 7 and 11 are respectively connected in known manner by common bulk air lines 12 to 15, typically about 5 cm (2 inches) in diameter. The air suspension system described so far is a typical Kenworth Airglide 200, which can be seen installed on the Kenworth T 904 tractor.

[0025] Normally, the common lines 12 to 15 on each side of the axle are connected by air lines (not shown) to suitable ride height control valves 16 and 17 (such as Hadley valves), but in this embodiment, respectively The common lines 12 to 15 are fed at the air line connector fittings of each air bag via separate air lines 18 to 21 on one side and air lines 22 ...

Abstract

An air suspension system for a multi-axle vehicle having air bags (4,5; 6,7; 8,9; 10,11; 44 to 49) supporting either side of the axles (2,3; 41 to 43), including separate air lines (18 to 25; 50 to 55) respectively connecting each air bag to a level control valve (16,17; 56,57) via manifolds (26,27; M) and air lines (28,29; 54,55) to independently control air supply to the bags on either side, the separate air lines being of the same size and length to ensure that substantially the same volume of air is supplied to each bag to improve the responsiveness and stability of the system.

Description

technical field [0001] This invention relates to improvements in air suspension systems for tractor and trailer vehicles having multiple axles supported by airbags on both sides of each axle. Background technique [0002] Air suspension systems for tractor vehicles that carry loads may include up to eight air suspension cells that support pairs of two drive shafts on either side of each shaft. In one known tractor, pairs of airbags are connected by a common large diameter air line extending between correspondingly positioned airbags on adjacent axles. [0003] The common air lines are each connected by an air line to a control valve that controls air supplied to the common air lines to adjust inflation of the air bags to ensure that the tow vehicle remains level as the tow vehicle travels over varying road conditions. [0004] In other air suspension systems, such as those of the Hendrickson HAS Series, each axle is supported on each side by a single large airbag mounted on...
