The invention relates to an air guide (10) particularly for a cooling module (12) of a front-end module (11) of a vehicle with an air guide body (20) which comprises an air inlet opening (21) and an air outlet opening (22) in order to guide air from the outside to the inside with regard to the vehicle. To this end, the invention provides that the air guide body (20) is configured from such a material (30) that the air guide body (20) can be transferred in the mounting state (I) and in the transport state (II) wherein the air guide body (20) assumes a significantly greater volume in the mounting state (I) than in the transporting state (II).

A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

An electric work vehicle includes: a battery pack that is arranged between a left rear wheel arranged outside of a left frame and a right rear wheel arranged outside of a right frame, the front end of the battery pack being located forward of an axle center of a rear wheel unit; a left motor that is arranged above the battery pack, in the periphery of the left rear wheel, receives a supply of power from the battery pack, and transmits rotational power to the left rear wheel; and a right motor that is arranged above the battery pack, in the periphery of the right rear wheel, receives a supply of power from the battery pack, and transmits rotational power to the right rear wheel.

The Double Barrel Mounting Hardware invention is a hardware application for attaching skateboard trucks to the underside of a skateboard deck. The hardware is shaped like an elongated U (Harness) and mounts from the underside of the skateboard trucks through two corresponding holes on either the left or right side of the skateboard truck. The Double Barrel Mounting Hardware spans across these two corresponding holes in the skateboard truck along the underside of the skateboard truck baseplate and has two 90 degrees turned barrels at each end to pass through the holes in the skateboard truck baseplate and into the underside corresponding holes in the skateboard deck. The barrel of the harness that goes through the skateboard trucks and into the skateboard deck contains female threaded barrels. Male threaded mating bolts engage the harness barrels from the top side of the skateboard deck and when threaded together the mating bolt and harness bond the skateboard deck and skateboard trucks together. This hardware system securely attaches the skateboard trucks to the underside of the skateboard deck to be used in skateboard riding maneuvers.

A power steering assembly for a hydraulic power steering system of motor vehicles includes an input shaft configured for connection to a steering wheel, an output shaft coupled to the input shaft configured for operational engagement with a steering rod, a hydraulic servo valve, an actuator, a sensor system, and an evaluation unit. The coupling between the input and output shafts is realized by a torsion bar and permits a first relative rotation between the input and output shafts. The hydraulic servo valve, which controls a hydraulic pressure and thus a steering assistance depending on the steering torque applied by a driver, has a rotatable control element engaged with, and driven by, the output shaft. An engagement between the output shaft and control element provides for a second relative rotation therebetween. This engagement includes a multi-stage planetary gear unit. The steering power assistance system is controlled depending on a third relative roation between the input shaft and control element. The actuator relatively displaces the control element in relation to the output shaft to influence the steering power assistance characteristics. The sensor system measures at least one differential angle between the control element and input shaft, wherein the control element is a valve sleeve disposed coaxially with the input and output shafts and the sensor system includes an encoder sleeve non-rotatably connected to the valve sleeve.

A motor vehicle rear structure includes an underframe component to support a motor vehicle floor and in which a tunnel is formed, an axle component including a central part and two lateral parts that define a space to accommodate a component of the vehicle, an articulation device including a first articulation element and a second articulation element which are able to pivot relative to one another, and at least one front reinforcing element fixed to the second articulation element and to the tunnel. The rear structure is arranged in such a way that said at least one front reinforcing element allows at least some of a load in the direction of travel of the motor vehicle derived from the axle component to be transmitted to the tunnel.

A steering system of a saddle-ride type vehicle including a front fork that includes a steering shaft at the upper end and supports a front wheel at the lower end, a steering arm that is attached to the steering shaft, a steering force transmit member that is turnably supported by a steering stem that is arranged in a body frame, and a steering system link that joins the steering arm and the steering force transmit member. An assist motor generates a steering assist force that assists a steering force transmitted to the steering shaft, and a steering assist force transmit member is turnably supported by the steering stem. An assist steering system link joins the steering arm and the steering assist force transmit member.

The present invention relates to a drivetrain having a first clutch, which has an input side and an output side which is selectively connectable in terms of rotational drive to the input side, and having a transmission, which has a transmission shaft which is connected or connectable in terms of rotational drive to the output side and which is selectively connectable in terms of rotational drive to a gearwheel by means of a second clutch, wherein a rotor of an electric machine is arranged on the output side, and the electric machine, in motor operation, can be controlled or regulated so as to cause the rotational speeds of the transmission shaft and of the gearwheel to be approximated to or aligned with one another before the closure of the second clutch. The present invention also relates to a method for performing gearshifts in a transmission within a drivetrain of the type according to the invention.

An electric crawler vehicle includes a pair of left and right traveling crawlers, a traveling electric motor that generates traveling power to be transmitted to the pair of left and right traveling crawlers, and a turning electric motor that generates turning power to be transmitted to the pair of left and right traveling crawlers. The traveling electric motor and the turning electric motor are disposed on one lateral side of the vehicle.
