Problems solved by technology

In other words, back pressure in the manifold block could slow or even reverse the airflow in the rear end of the vehicle, causing the rear end of the vehicle to not lower at all or actually rise, causing the vehicle to lean at an uncomfortable angle

Embodiment Construction

[0026] Referring to the drawings, wherein like numerals designate corresponding parts throughout the several views, in figure 1 A parallel leveling system 20 for a vehicle is shown generally in .

[0027]Parallel leveling refers to raising and lowering the vehicle pneumatically in a smooth manner without switching the air spring blocker valve. Typically, parallel leveling system 20 is implemented in a vehicle having a front end, a rear end, and a plurality of wheels (eg, four wheels) including a pair of front wheels and a pair of rear wheels. A plurality of air springs 22, 24 are connected to the vehicle. The plurality of air springs 22 , 24 includes a pair of front air springs 22 and a pair of rear air springs 24 . Front air springs 22 are spaced apart from each other and connect the vehicle to the front wheels of the vehicle for damping relative forces between the vehicle and the front wheels. Additionally, front air springs 22 raise and lower the front end of the vehicle...

Abstract

Parallel leveling system for vehicles. A parallel leveling system includes a source of pressurized air. A manifold block having a body defining an air supply inlet is disposed between the air spring and the source of pressurized air. The main body includes a front suspension valve and a rear suspension valve. Each of the suspension valves defines a suspension valve orifice having a first predetermined diameter. The body includes at least one restrictor valve parallel to and in fluid communication with the front suspension valve. The at least one restriction valve includes a first check valve and a first stop valve orifice defining a first orifice diameter. A first check valve and a first shut-off valve orifice are arranged parallel to each other and in series with the front suspension valve and in fluid communication with the air supply inlet and the front suspension valve for reducing fluid backflow to allow the vehicle to operate at nominal reduced under load conditions.

Description

technical field [0001] The present invention relates generally to a parallel leveling system, and more particularly, to a parallel leveling system for a vehicle. Background technique [0002] Parallel leveling systems are known in the art for motor vehicles to provide smooth, pulse-free raising and lowering of the front and rear ends of the vehicle while requiring minimal switching between separate front and rear axle airflow controls. Such parallel leveling systems typically include a plurality of air springs, each for interconnecting the body of the motor vehicle with one of the wheel suspension members, for damping relative forces between the body and the wheels, and for Adjust the height of motor vehicles. [0003] To control airflow in parallel leveling systems, air springs are typically connected via one or more air lines to the manifold block of the air management system. The parallel leveling system may also include a compressor and / or pump including a motor that m...
