A split-type hard front axle includes an axle housing; an axle tube connected to the axle housing; an inner-C-forging connected to the axle tube and configured for connecting with a kingpin knuckle; and a connection structure cooperated with the inner-C-forgoing for detachably fixing the inner-C-forging on the axle tube. The axle tube includes a first angle adjustment structure. The inner-C-forging includes a second angle adjustment structure. A portion of the inner-C-forging is capable of deforming under a force exerted by the connection structure, to fix the inner-C-forging on the axle tube. The first angle adjustment structure is capable of cooperating with different portions of the second angle adjustment structure to make the inner-C-forging have different installation angles on the axle tube, and a caster to pinion angle is being different at inner-C-forging's different installation angles. A vehicle is also provided.

An axle assembly for frame rail vehicles is described herein. The axle assembly includes a first axle shaft and a second axle shaft orientated along a first axis of rotation. A first electric machine is orientated along a second axis of rotation and a second electric machine is spaced from the first electric machine and orientated along a third axis of rotation. A differential gear set is disposed about the first axis of rotation and is coupled to and driven by a common gear reduction to transfer rotational torque from the first and second electric machines to the first and second axle shafts. A speed change mechanism is coupled between the common gear reduction and the differential gear set to change the rotational torque transferred to the first and second axle shafts.

An axle shaft disconnect clutch includes a housing, an axle shaft, a stub shaft, a dog clutch and an inner race. The axle shaft includes a first outer spline and the stub shaft includes a second outer spline. The dog clutch has an inner spline engaged with the second outer spline and the inner race is rotationally fixed and axially displaceable relative to the housing to axially displace the dog clutch and engage or disengage the inner spline with the first outer spline. In some example embodiments, the axle shaft disconnect clutch has a bushing pad fixed to the inner race. The inner race is arranged to push the dog clutch towards the first outer spline to engage the dog clutch, and the inner race is arranged to pull the bushing pad to pull the dog clutch away from the first outer spline to disengage the dog clutch.

The present disclosures relate to methods and systems for a hybrid powertrain. The hybrid powertrain system includes an integrated axle configured to provide mechanical power to a first pair of wheels, the integrated axle comprising a first motor-generator and a first drive axle such that the first motor-generator and at least a portion of the first drive axle are mechanically coupled to a common housing. The system also includes a second motor-generator configured to be mechanically coupled with an engine via a first clutch and mechanically coupled with a second drive axle via a second clutch, the second drive axle mechanically coupled with a second pair of wheels. A controller is electrically coupled with the first and second motor-generators, the engine, and the first and second clutches, the controller configured to enable a fully electric mode, a series hybrid mode, a parallel hybrid mode, and a regenerative mode of operation.

Provided is a hub unit (1) with a steering function. The hub unit (1) includes a hub bearing assembly (3) including a hub bearing (21) configured to rotatably support a wheel (13) of a vehicle (11), a unit support member (5) configured to be coupled to a suspension system (33) and supporting the hub bearing assembly (3), and a rotation-permitting support member (7) rotatably supporting the hub bearing assembly (3), about a turning axis (A) that extends in a vertical direction, on the unit support member (5).
