An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit is configured to independently adjust air pressure of a first side of the vehicle. The second pneumatic circuit is configured to independently adjust air pressure of a second side of the vehicle. The system is configured to establish pneumatic communication between the first and second pneumatic circuits when the air management system is not independently adjusting the adjust air pressure of the first side of the vehicle and the air pressure of the second side of the vehicle in the cross-flow mode.

A suspension kit is provided for use in heavy duty vehicles having an independent front suspension including air springs, the kit includes an anti-roll bar having two ends, each end configured for connection to the front suspension in operational relationship to an associated one of two front wheel assemblies, at least one ping tank in fluid communication with an associated one of the air springs, a valve in fluid communication between each at least one ping tank and the associated air spring, a control switch connected to each valve for moving the valve between an open position, allowing fluid communication between the at least one ping tank and the air spring, and a closed position, closing fluid communication between the at least one ping tank and the air spring. An associated front suspension is also provided.

The present invention relates to a forecarriage of a rolling motor vehicle with three or four wheels, comprising: a forecarriage frame (16); at least one pair of front wheels (10, 10) kinematically connected to each other and to the forecarriage frame by a kinematic roll mechanism (20) which enables the same to roll in a synchronous and specular manner; a roll control system (100) comprising a rod (110) having a first (111) and a second end (112) opposite each other which connect by means of hinging means (101, 101; 102, 102) a first (60) and a second anchoring portion (60) of forecarriage (8) directly to each other. At least one of said first and second anchoring portions is subject to roll movements of said two front wheels. The hinging means are configured to passively follow the movements of the two anchoring portions. The hinging means (101, 101) at the first end of the rod comprise at least a first roll hinge (101) which has its hinge axis substantially orthogonal to a rolling plane of the two front wheels and is connected to the first anchoring portion. The roll control system comprises a first damper device suitable to dampenin a predetermined angular rangethe rotation movements of the rod with respect to the first roll hinge at the first end (111). The above angular range corresponds to the angular roll range of the rod.

A structure of rocking controller of a saddle riding type vehicle includes a rocking lock mechanism configured to lock lateral rocking of the vehicle body; wherein the rocking lock mechanism includes an arc shaped lock plate which crosses with an axial direction of a rocking shaft of the vehicle body and a lock caliper configured to lock a relative rocking between the lock plate and the lock caliper by clamping the lock plate, and a motor for the actuator is arranged in front of the rocking lock mechanism and the rotating drive shaft of the motor is arranged so as to penetrate an inner circumferential region of the arc shaped lock plate.

A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end, a second actuator coupled to the first end, a third actuator coupled to the opposing second end; and a fourth actuator coupled to the opposing second end. The first actuator and the second actuator are selectively engageable to facilitate providing active control of a first pitch adjustment and a first roll adjustment of the first end of the chassis. The third actuator and the fourth actuator are (i) selectively fluidly couplable to facilitate providing passive control of a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis and (ii) selectively fluidly decouplable to facilitate providing active control of the second pitch adjustment and the second roll adjustment of the opposing second end of the chassis.

A body structure includes at least one aluminum side rail, which allows the assembly of an aluminum cradle of a vehicle by an aluminum casting including an upper surface attached under the side rail, one or more lower portions attached to the cradle, and an opening allowing the passage of an drive shaft. The casting can also incorporate suspension interfaces.

Automatic tilting vehicle is provided that includes left and right front wheels supported by knuckles, a rear wheel steered by a steering actuator, a vehicle tilting device, and a control unit. The control unit calculates a target tilt angle of the vehicle and a target steered angle of the rear wheel based on a steering angle and a vehicle speed, controls the vehicle tilting device so that a tilt angle of the vehicle becomes the target tilt angle, and controls the steering actuator so that a steered angle of the rear wheel becomes the target steered angle. When the vehicle is turning and decelerating, a steered angle of the rear wheel is controlled not to be the target steered angle but to zero, and a tilt angle of the vehicle is reduced by a gyro moment of the rear wheel.

A suspension device (rear suspension (10)) for vehicles is provided which includes a damper (40), a shaft (50) pivotably supporting an end of the damper (40), and a bush (60) including a cylindrical elastic member fitted onto the outer circumference of the shaft (50). The axis (C2) of the bush (60) is disposed along a line of intersection between an imaginary first plane (S1) and an imaginary second plane (S2), or along a line parallel to the line of intersection. The first plane (S1) is orthogonal to the axis (C1) of the damper (40) when a stroke position of a wheel (24) is a first position relative to the vehicle body (80) in the vertical direction of a vehicle body (80). The second plane (S2) is orthogonal to the axis (C1) of the damper (40) when the stroke position of the wheel (24) is a second position.

There is described a wheel axle for an agricultural vehicle such as a combine harvester. The wheel axle has at least one wheel suspension (32a) arranged to maintain a wheel axle parallel to the supporting surface, through use of a linkage arrangement (36, 38, 40) which is pivotally coupled to the axle frame (30). The configuration of the wheel suspension allows for the wheel axis to passively follow the surface profile, as any loads transmitted through the wheel carrier act to level out the wheel suspension to align with the underlying surface. As the wheel axle is adjusted to lie parallel with the underlying surface, accordingly the ground-contacting surface area of the associated wheels is maximised.
