The invention relates to a lifting machine (1) comprising a lifting arm (3), a rolling chassis (2) equipped with at least one front axle (5) and one rear axle (6), and a sensor for measuring the tilt of the lifting arm (3) in relation to the chassis (2), the rear axle (6) being pivotably mounted around an axis that is parallel to the longitudinal axis of the machine (1). The rear pivoting axle (6) is mounted to freely pivot inside an angular range defined by two abutments supported by said chassis (2), the front axle (5) is coupled to the chassis (2) by a pivoting connection with an axis that is parallel to the longitudinal axis of the machine (1) and is equipped with an activatable/deactivatable suspension (9) in order to allow the relative pivoting between the front axle (5) and the chassis (2) to be damped, said suspension (9) being deactivated at least when the angle value measured by sensor (4) for measuring the tilt of the lifting arm (3) is greater than a predetermined threshold value.

Tipping over of a work machine is prevented. The work machine includes: a vehicular body; a rear axle attached to the vehicular body to be capable of undergoing a roll motion with respect to an axis extending in a front-rear direction of the vehicular body; and a controller. The controller acquires stability of the center of gravity of the vehicular body, and controls the roll motion of the rear axle with respect to the vehicular body based on the stability.

Sensor device for determining the spatial position of the coachwork or body of a vehicle wherein inclinations or existing distances in each case relative to one another of the body or coachwork and axles or chassis and/or road surface are measurable via the sensor device and the signals from the sensor device corresponding to the determined inclinations or distances are transmittable to an electronic control device of a level-regulating system and are processable there in a regulating algorithm, wherein the sensor device has a combination of at least one distance-measuring sensor and an inclination sensor, and also an electronic evaluation unit, wherein the sensor signals from both sensors are processable by the electronic evaluation unit and are transmittable to the electronic control device.

A cam washer for a vehicle suspension system includes a point of rotation about which the washer is configured to rotate, and an outer surface profile where any point along the outer surface profile is configured to provide a friction angle less than a predetermined value to prevent the cam washer bolt from rotating under a load acting on the outer surface profile, the outer surface profile being a function of: i) a shortest distance from the point of rotation to the outer surface profile, ii) a longest distance from the point of rotation to the outer surface profile, iii) a position angle of the outer surface profile, and iv) a coefficient of friction of a material of the washer.

A lane keeping system for a vehicle includes a first roll angle sensor configured to provide a first signal indicative of dynamic vehicle body roll. A second roll angle sensor is configured to provide a second signal indicative of an angle between vehicle sprung and unsprung masses. A lane keeping system (LKS) controller is in communication with the first and second roll angle sensors. The LKS controller is configured to discern a vehicle roll angle in response to the first and second signals based upon effects of a lateral wind force on the vehicle. The LKS controller is configured to produce a correction in response to the determined lateral wind force effects to maintain the vehicle along a desired path.

An aircraft landing gear assembly (112) including a shock absorber strut (114), a bogie (120), a link assembly (124), and a movement detector (132). The shock absorber strut includes an upper and a lower telescoping parts (118, 116), the upper part being connectable to the airframe of an aircraft and the lower part being connected to the bogie. The link assembly extends between the upper and lower telescoping parts. The movement detector detects movement of the link assembly relative to the bogie. The movement detector includes: a piston (138) arranged such that relative movement between the link assembly and the bogie causes relative movement of the piston within a cylinder (136); fluid which flows as a result of relative movement between the piston and the cylinder; and a flow sensor (184) arranged to sense a change in flow due to movement of the piston within the cylinder.

The invention relates to a chassis component with a structural part which comprises at least one strut section with an open cross-section shape, wherein in an end area of the strut section a first wall section and a second wall section are formed, the first wall section has a first joint-receiving opening and the second wall section has a second joint-receiving opening. The two joint-receiving openings are arranged opposite one another, and a joint housing of a joint is arranged in the two joint-receiving openings. In order to improve the arrangement of an additional component, in particular a sensor element, on the chassis component and make it simpler and/or less costly, the said additional component is fixed between the two wall sections and on the joint housing by means of a clamping fit and/or a press fit.

A system and method calculates a vehicle load on a suspension system of a vehicle using a plurality of tilt angle sensors. The angle sensors are attached to the suspension system and configured to measure an angle with respect to gravity. A first angle sensor is configured to measure a first angle. A second sensor configured to measure a second angle. The measured first and second angles are combined to obtain a combined value representative of a vehicle load adjusted for tilt.

A vehicle comprising a first leaf spring connected to a chassis so as to, while deflecting, allow relative vertical movement between the chassis and a wheel axle and thereby also between the chassis and wheels, and a control circuitry configured to: compare the signal indicative of the actual path followed by the wind-up center with a representation of a reference path that the wind-up center of the first leaf spring should follow when the first leaf spring is well-functioning and deflects as intended; determine whether a difference between the actual path and the reference path is greater than a threshold value; and, in response to the determined difference greater than the threshold, generate an alarm signal indicative of a detected or possibly detected leaf spring failure.

An air suspension system of a commercial vehicle comprises an electronic control device with a level control valve device. A valve element is coupled to a drive element mechanically coupled to a vehicle wheel or axle. In a first relative position of the valve element and a counter valve element, a port for an air suspension bellow is blocked. In a second relative position, the port for the air suspension bellow is connected to a port for an aeration device. In a third relative position, the port for the air suspension bellow is connected to a port for a deaeration device. Control logic generates a control signal for an actuator which, when a level change is set by an operator, correspondingly changes the relative position of the valve element and the counter valve element or the relative position of the counter valve element and a valve housing.
