Driven lift axles and associated systems and components are provided for use on heavy duty trucks, trailers, and/or other vehicles. Driven lift axle systems may include one or more motors mounted to the lift axle to provide torque to drive one or more wheels of the lift axle. Various mounting configurations of such motors are possible, such as arranging a motor on the axle to provide torque at a conventional driveshaft input by interfacing with a differential drive gear, positioning a motor at each of the wheel ends of the axle to provide torque directly to the wheels, etc. Each wheel can be driven by a separate motor, allowing for independent control of the torque applied to each wheel. Lift axles described herein can be suitable for use with various motors capable of applying torque to the axle and/or wheels, such as electric motors, hydraulic motors, internal combustion engines, etc.

A suspension system for a rear axle of a vehicle provided with a frame equipped with at least two side members, the suspension system connecting the axle to said side members and comprising a left side and a right side, each comprising an axle-holder assembly, a bellows, a leaf spring, first and second bars, and a torsion bar interposed between said left and right sides. The aforementioned elements of the suspension system being arranged to provide a functional layout having reduced costs and overall dimensions.

A utility vehicle with ergonomic, safety, and maintenance features is disclosed. A vehicle is also disclosed with improved cooling, suspension and drive systems. These features enhance the utility of the vehicle.

A work vehicle includes: a wheel support member configured to support a pair of left and right traveling wheels; a link mechanism configured to support the wheel support member such that the wheel support member can be raised and lowered, the link mechanism being provided spanning between a vehicle body and the wheel support member; a suspension mechanism configured to elastically support the wheel support member, the suspension mechanism being provided spanning between a suspension support portion, which is formed on the vehicle body, and the wheel support member; and a lateral link configured to restrict leftward and rightward movement of the wheel support member, the lateral link being joined to a vehicle body-side support portion, which is formed on the vehicle body, and to a wheel-side support portion, which is formed on the wheel support member, wherein the link mechanism has: an upper link with an front end portion supported so as to be able to pivot up and down around an upper pivot axis by a link support portion, which is formed on the vehicle body, and with a rear end portion joined so as to be able to relatively pivot around an upper joint axis by the wheel support member; and a lower link with a front end portion supported so as to be able to pivot up and down around a lower pivot axis by the link support portion, and with a rear end portion joined to the wheel support member so as to be able to relatively pivot around a lower joint axis, a distance between the upper pivot axis and the upper joint axis is set shorter than a distance between the lower pivot axis and the lower joint axis, a gap width between the upper joint axis and the lower joint axis is set larger than a gap width between the upper pivot axis and the lower pivot axis, and when the vehicle body is in an unloaded state, the lower joint axis is located lower than the lower pivot axis.

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.

Disclosed herein is an adjustable suspension mount system that includes a first mount link pivotally attached to a mount feature and extending to a device used to support a load on a first wheel, the first mount link pivotally attached to the device. The mount feature is attached to or integrated into the frame of the vehicle. The system further includes a second mount link pivotally attached to at least one of the mount feature and a second mount feature, the second mount link extending to the first mount link, the second mount link pivotally attached to the first mount link. Further disclosed is a vehicle including the system, and a kit including the components to provide the system for a vehicle.

An electric vehicle comprising a portal axle architecture. The electric vehicle having a frame. An axle assembly including a De Dion tube. A first wheel hub and a second wheel hub rotatably coupled with the De Dion tube. A suspension system coupled with the vehicle frame, the suspension system having at least one pair of trailing arms pivotally coupled with the vehicle frame and at least one pair of air springs. A first electric drive assembly in driving engagement with the first wheel hub, and a second electric drive assembly in driving engagement with the second wheel hub.

A suspension system for a traveling vehicle body is disclosed. The system includes a suspension reference position varying mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism (100), and a controller (35) configured to calculate an intermediate value from a maximal value corresponding to the maximal position of the suspension stroke and a minimal value corresponding to the minimal position of the suspension stroke, and to control the suspension reference position varying mechanism such that, when the calculated intermediate values deviates from a set target range, the intermediate value is displaced toward the target range. The controller (35) increases a control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is low, and reduces the control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is high.

A utility vehicle with ergonomic, safety, and maintenance features is disclosed. A vehicle is also disclosed with improved cooling, suspension and drive systems. These features enhance the utility of the vehicle.

A portal axle arrangement 1 for a motor vehicle includes at least one portal housing 2 and at least one suspension arm 5, 6. The at least one portal housing 2 includes a receiving section 7 for a portal gear and at least one connecting section 8, 9 for the at least one suspension arm 5, 6, in which the at least one connecting section 8, 9 is designed as a support section. A motor vehicle including such a portal axle arrangement is also provided.
