Abstract:
A method of leveling a stationary vehicle chassis (4) includes the steps of comparing the signal from an alignment sensor (65) to alignment data stored in an electronic control unit (42) and then operating the electronic control unit (42) to permit communication between one or more fluid suspension members (6, 7, 8, 9) and one of a pressurized fluid source (22) and exhaust (27) until the signal from the alignment sensor approximately corresponds to the aligment data. A system (1) for performing the method is also discussed.
Abstract:
Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.
Abstract:
A gas spring end member has an end member axis and is dimensioned for securement to an associated flexible spring member. The gas spring end member includes an end member wall with a base wall portion disposed transverse to the end member axis. An outer wall portion extends axially from along the base wall portion. A mounting wall portion is dimensioned to receivingly engage an associated end of the associated flexible spring member. An end wall portion extends peripherally about the end member axis and operatively connects the outer wall portion and the mounting wall portion to at least partially define an end member volume. An inner wall portion separates the end member volume into an end member reservoir disposed outward of the inner wall portion and an end member chamber disposed inward of the inner wall portion. Gas spring assemblies and suspensions systems are also included.
Abstract:
The subject invention reveals a distance measuring device comprising: a sensing module, a target module, and an evaluating module, wherein the sensing module and the target module are mountable so as to execute a movement with respect to each other along a movement trajectory, wherein the target module comprises a magnetic field generating element (3) having a magnetic pole axis, wherein the sensing module comprises a first magnetic field sensing array (MFS1) being arranged distant to the movement trajectory. MFS1 comprises a first magnetic field sensor (L2) and a second magnetic field sensor (L3), wherein a main sensing direction of the first magnetic field sensor (L2) is inclined with respect to a main sensing direction of the second magnetic field sensor (L3). The sensing module and the target module can advantageously be situated within the pressurizable chamber of an air spring which is defined by (contained within) a first mounting plate, a second mounting plate, and a flexible member of the air spring.
Abstract:
The invention relates to a method for estimating an amount of compressed air supplied to an air bellows (10) which forms part of an air supply system of a vehicle. The magnitude of an amount of compressed air supplied to the air bellows (10) is calculated by means of a computing model on the basis of the measured value representing the bellows height of the air bellows and the measured value representing the bellows pressure of the air bellows. The invention also relates to a computer programme product comprising computer programme codes for implementing a method according to the invention, and to an electronic control unit.

Abstract:
The invention relates to a method for controlling air flow in a level control system for a motor vehicle. Two air flow intervals are indicated for controlling air flow. The first air flow interval I1 is located entirely within air flow interval I2. If the air flow in the level control system is located outside air flow interval I2, an automatic adjustment is made in air flow interval I2. If the air flow is still located outside air flow interval I1 and within second air flow interval I2, the air flow is adjusted to the first air flow interval I1 exclusively when the motor vehicle is in operation.
