Abstract: A drive device for a motor vehicle includes a primary powertrain and a secondary powertrain, wherein the primary powertrain includes a combustion engine for generating a total torque; a torque distribution device coupled to the combustion engine and including a first and a second output, wherein the torque distribution device is designed to provide a first partial torque in mechanical form at its first output derived from the total torque, and to provide a second partial torque in electrical form at its second output derived from the total torque; and a transmission which is coupled to the first output of the torque distribution device; wherein the secondary powertrain includes an electric machine which is coupled to the second output of the torque distribution device; wherein the torque distribution device includes a torque limiting device which is designed to limit the first partial torque to a presettable threshold value.

Abstract: A leg structure includes: a pair of first-stage leg servos connected to the waist structure, each of the first-stage leg servos including a first output shaft; second-stage leg servos corresponding to and arranged opposite to the first-stage leg servos, the second-stage leg servos including second output shafts perpendicular to the first output shaft; a pair of connecting assemblies each used for mounting one of the first-stage leg servos and one of the second-stage leg servos, the connecting assemblies each including a connecting member for mounting one end of the first output shaft and one end of the second output shaft, a first end cover fixed to the connecting member and used for mounting the other end of the first output shaft, and a second end cover fixed to the connecting member and used for mounting the other end of the second output shaft.

Abstract: At a given insertion depth (D) of a drawbar (22, 60) in a trailer hitch receiver tube (24, 68), a pin arm (26, 56, 74) attached to the drawbar extends forward beside the receiver tube and holds a captive pin (21, 51, 76) beside a pin receiving hole (30, 71) in the receiver tube. A spring (36) urges the captive pin into the pin receiving hole to retain the drawbar in the receiver tube. The pin arm may be attached to the drawbar via a crossbar (40, 70, 73). Receiver tubes of different sizes (24, 68) may be accommodated by a drawbar size adapter (62) that slips over the drawbar, enlarging it, and by a vertical adjustment mechanism (83) for the pin arm (74) that aligns the pin with the pin receiving hole in either a smaller (24) receiver tube or a larger (68) receiver tube.
