20130333959 | Steering axle for agricultural vehicles - A steering axle is provided for agricultural vehicles having at least two drive motors for at least two land wheels on either side of the steering axle disposed next to one another substantially in the center between the land wheels. A mechanical drive train between the drive motor and the wheel hub is provided on both sides. | 12-19-2013 |
20140284121 | STRUCTURE OF TRAILING ARM FOR VEHICLE - A structure of a trailing arm for a vehicle according to the exemplary embodiment of the present disclosure may include a trailing arm disposed between a vehicle body and a wheel to absorb torsion generated at the wheel. A drive motor is disposed in an interior space of the trailing arm and serves as a power source of the vehicle. A decelerator is disposed to selectively change a rotation speed of the wheel by receiving a torque of the drive motor. | 09-25-2014 |
20160039277 | Hybrid Axle Assembly For A Motor Vehicle - An axle assembly for an electric or hybrid vehicle includes electrically powered drive motors for respectively driving vehicle wheels. The axle assembly preferably includes a dual motor arrangement, wherein two electric motors are arranged end-to-end. Each motor includes an inverter that is directly connected to its respective motor, and includes a gearbox assembly coupled between an output of the motor and a corresponding constant-velocity (CV) joint operatively connected to a wheel. The inboard ends of the motors are secured to opposite faces of a cooling manifold wherein the cooling manifold maintains the motors in axial alignment. The cooling manifold plate is positioned between an inboard end of each of the motor housings, and the cooling manifold plate axially aligns the first and second motors. Further, each motor drives its respective gearbox assembly, which includes a gear reduction and clutch mechanism having a brake band assembly that is selectively operable to disconnect the respective motor from the vehicle wheel associated therewith. | 02-11-2016 |
20160083012 | Arrangement of a Rear Axle Module on a Vehicle Body, and a Rear Axle Module for Such an Arrangement and a Two-Axle, Two-Track Vehicle Which is at Least Partially Driveable by Means of an Electric Motor and Has Such an Arrangement - An arrangement of a rear axle module on a two-axle, two-track vehicle which is at least partially electrically driveable by an electric motor is provided in which a rear axle bracket designed for the fastening of wheel-guiding links of a rear axle and a housing for accommodating components for providing electrical energy together form the module, with the housing arranged in a front region of the rear axle module. The rear axle module includes bearing brackets by which the module is connected from below to the vehicle body, including two rear axle bracket bearings which are to the rear of the rear axle module with respect to the direction of travel, two central rear axle bracket bearings arranged in a central region of the rear axle module, and two front bearings arranged on the housing in the front region of the rear axle module. | 03-24-2016 |
