A tag axle system for a concrete mixing vehicle including an axle including a right wheel assembly and a left wheel assembly, an actuator coupled to the axle to move the axle between a raised position and a lowered position relative to a vehicle chassis, a stabilizer mount plate structured to be coupled to the vehicle chassis, a stabilizer bar rotationally coupled to the stabilizer mount plate, a right stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the right wheel assembly, and a left stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the left wheel assembly.

A pneumatic suspension system for a vehicle, in which the pneumatic suspension system includes a supply tank, a first set of air springs positioned on a first side of the vehicle; a second set of air springs positioned on a second side of the vehicle, and a dual-action dynamic valve positioned between the first set of air springs and the second set of air springs. The dual-action dynamic valve is connected to the supply tank, the first set of air springs, and the second set of air springs by a series of air hoses. The dual-action dynamic valve is adapted to supply air to either one of the first set of air springs or the second set of air springs while simultaneously exhausting air from the other one of the first set of air springs or the second set of air springs.

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.

Embodiments of a suspension for a vehicle is provided. The suspension includes, for example, a frame and a locking assembly. The locking assembly inhibits tipping of a frame of the vehicle when tipping of the frame is detected.

Disclosed is a vehicular suspension control assembly and a kit of parts therefore configured to connect to opposite ends of a vehicle axle housing and to opposite sides of the vehicle. The assembly includes a control module configured to connect to the opposite ends of the vehicle axle housing and a frame module configured to connect to the opposite sides of the vehicle. The control and frame modules are interconnected with pivot control members to allow both modules to keep equal weight on the rear wheels during vehicle cornering. The control module has a straight pivot link connected to one side of the axle housing and an interconnected asymmetrical pivot link connected to the other side of the axle housing. When cornering, additional weight is applied to one side of the axle housing. In response, the pivot links of the control assembly transfer weight to the other side of the housing, to keep equal weight on the rear wheels.

An active roll control apparatus is provided. To adjust a stiffness value of the stabilizer bar by moving a stabilizer bar installed between left and right wheels of a vehicle and extending in a first direction and a stabilizer link connected to the stabilizer bar, the active roll control apparatus includes a sliding part having one side connected to the stabilizer bar and the other side connected to the stabilizer link to slide the stabilizer link in a second direction perpendicular to the first direction, and a movement restricting part installed at the sliding part to restrict movement when the sliding part slides.

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 dampen—in a predetermined angular range—the 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 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.

Embodiments of a suspension for a vehicle is provided. The suspension includes, for example, a frame and a locking assembly. The locking assembly inhibits tipping of a frame of the vehicle when tipping of the frame is detected.

A suspension system having a knuckle carrier. A pivot mechanism may pivotally couple a control arm to the knuckle carrier. The pivot mechanism may include a preload nut that may exert a preload force on a bearing assembly. A platform may be fixedly disposed on the knuckle carrier. The platform may support an air spring and may have an arm that is coupled to a stabilizer bar subassembly.
