An axle assembly having an electric motor, a wheel end assembly, and a reduction gear module. The electric motor may have a rotor that is rotatable about a first axis. The wheel end assembly may be rotatable about a second axis that may be disposed above the first axis. The reduction gear module may transmit torque between the electric motor and the wheel end assembly.

The invention relates to a running gear structure (4) for a commercial vehicle. The running gear structure comprises a lower transverse strut (8) and an upper transverse strut (9). The lower transverse strut (8) and said upper transverse strut (9) are fixedly connected to each other. The upper transverse strut (9) comprising two recesses (12, 13) which limit a space (14) located above the lower transverse strut (8). The space (14) is open at least in upper direction and dimensioned for accommodating a suspension spring (6). Preferably, an axle body and longitudinal swinging arms (22, 23) of the running gear structure (4) have a skeletal design with a plurality of struts (5). It is possible that the running gear structure (4) is L-shaped in a side view. Here, one leg of the L is formed by a horizontal structure part forming the longitudinal swinging arms (22, 23) whereas the other leg of the L is formed by a vertical structure part forming the axle body.

An axle assembly having a drop gear set and a countershaft transmission. The drop gear set may operatively connect a rotor of an electric motor to a countershaft. The countershaft transmission may operatively connect the countershaft to a drive pinion. The electric motor and the countershaft transmission may be positioned on opposite sides of a differential assembly.

A leading-edge steering system is provided for a front suspension of an off-road vehicle. The leading-edge steering system is comprised of a spindle assembly that supports a drive axle assembly to conduct torque from a transaxle to a front wheel. A first rod-end joint pivotally couples an upper suspension arm and the spindle assembly, and a second rod-end joint pivotally couples a lower suspension arm and the spindle assembly. A steering rod-end joint pivotally couples a first end of a steering rod with a leading-edge portion of the spindle assembly. A steering gear is coupled with a second end of the steering rod and configured to move the steering rod, such that the spindle assembly rotates with respect to the upper and lower suspension arms. The leading-edge portion is configured to exert primarily tensile forces on the steering rod during travel over rough terrain.

An axle of an industrial vehicle, in which a parking brake can be maintained easily. The parking brake is arranged adjacent to a power transmission device outside an axle housing. The parking brake includes a brake housing, a brake shaft supported rotatably around the axis of the brake housing, a brake gear attached to the brake shaft and meshed with a transmission gear, first brake plates attached to the brake shaft, second brake plates attached to the brake housing and alternately arranged with the first brake plates, and a brake piston arranged so as to move toward and away from the plates and in the brake housing for bringing the plates into pressure contact with each other.

An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.
