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 system for suspending an automobile using an air rear suspension is provided. The system may include an automobile having a body, a front axle, and a rear axle; a linkage bar connected to said body and to said rear axle, wherein said connections allow for relative movement between said body and said rear axle; a cantilever bar having a first cantilever end and a second cantilever end; a damper; and an air spring, wherein said cantilever bar is connected to each of said rear axle and said body at said first cantilever end, wherein said cantilever bar is connected to each of said damper and said air spring at said second cantilever end, wherein said damper and said air spring are each connected to said body, and wherein said linkage bar and said cantilever bar are each configured to move in response to movement of said rear axle relative to said body.

The invention relates to an assembly (1) of a frame member (2) for an electric vehicle comprising a transverse member (14) with at each end a housing (10,10) connected to the transverse member (14) and two in-wheel motors (3,3) connected to a respective housing. Each motor comprises a brake drum (35) connected to a rotor (24), extending coaxially within the housing (10,10) near an inner surface a circumferential wall (8) of the housing. A brake shoe assembly (51,52,55,56) is movable in a radial direction R against the brake drum (35), and an actuator (18,18) is placed on an outer surface (17,17) of the circumferential wall (8,8) of the housing (10,10), connected to the brake shoe assembly (51,52,55,56). The assembly provides a low-floor portal frame member, with two in-wheel motors and a brake system that has relatively small axial dimensions and provides a reduced space envelope at the vehicle side.

A utility vehicle comprises a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame includes a front frame portion, a mid-frame portion, and a rear frame portion. The utility vehicle further comprises an attachment supported at the front frame portion. Additionally, the utility vehicle includes an operator area supported by the frame and including an operator seat and an adjacent passenger seat spaced apart from the operator seat. The operator seat and the passenger seat are in a side-by-side arrangement. The utility vehicle also comprises an auxiliary power assembly having an attachment shaft configured to be operably coupled to the attachment. The attachment shaft extends in a generally longitudinal direction of the utility vehicle and projects outwardly from the front frame portion.

A vehicle axle (10), including: a left axle (12L), a first side thereof being pivotally connected (50L) to a left wheel hub (14L); a right axle (12R), a first side thereof being pivotally connected (50R) to a right wheel hub (14R); a connector (20), disposed between second sides of the left (12L) and right (12R) axles for pivotally (28) connecting therebetween, for allowing pivotal motion therebetween; a first mechanism (52A,52B) for allowing and disallowing the pivotal motion between the left (12L) and right (12R) axles.

Systems and apparatuses include a chassis mount configured to couple to a vehicle chassis, an axle assembly including wheels, a four-bar linkage coupling the axle assembly to the chassis mount, and a hydraulic cylinder coupled between the chassis mount and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position and acts as a spring damper suspension component.

A work vehicle according to the present invention includes left and right axle cases of a rigid axle type, and left and right suspension mechanisms movable in the up-down direction relative to body frames and separately supporting the left and right axle cases, respectively. The work vehicle also includes (i) a first projection projecting downward from the left or right one of the body frames, (ii) a second projection projecting upward from that position on either the left and right axle cases or a frame body integrated with the axle cases which is opposite to the first projection in the left-right direction, and (iii) a lateral rod having a first end connected with the first projection and a second end connected with the second projection.
