The towbar with a hitch ball system may include a first bushing member, a second bushing member telescopingly engaged with the first bushing member, the second bushing member including at least one aperture, and a pivoting arm telescopingly engaged with the second bushing member. The towbar with a hitch ball system may also include an engagement device operatively coupled with the second bushing member, the engagement device including a pin member and an electrically-operating device, where the electrically-operating device generally aligns the pin member with the at least one aperture of the second bushing member.

An assembly includes a vehicle frame, a base fixed relative to the vehicle frame, and a hook supported by the base and rotatable relative to the base between an extended position and a retracted position. One of the hook or the base has a flange and the other of the hook or the base has a pair of extensions. The flange is between the extensions. A post is fixed relative to the flange and engages both extensions. A spring is connected to the post and one of the extensions. The spring is positioned to bias the hook toward the extended position.

In order to connect a trailer hitch, comprising a ball neck, which is movable between an operative position and a rest position and has a pivot bearing body arranged at a first end and a coupling ball arranged at a second end, a pivot bearing unit, which is arranged fixed to the vehicle by means of a carrier that is configured to be secured to a vehicle body, wherein by means of the pivot bearing unit, which has a pivot bearing housing, the pivot bearing body is mounted such that it is pivotal about a pivot axis between the operative position and the rest position, and a rotation-blocking device that, in at least one rotation-blocking position, blocks a pivotal movement of the pivot bearing body about the pivot axis in relation to the pivot bearing unit and, in a release position, releases such pivotal movement, to the carrier in a manner that is stable and simple to assemble, it is proposed that the pivot bearing housing should pass through a receptacle in a bearing part of the carrier and in so doing be held by positively engaging elements such that it cannot rotate in relation thereto, and that on either side of the receptacle the pivot bearing housing should be fixed by support bodies that abut against the bearing part and are supported against both the pivot bearing housing and the bearing part.

The invention relates to a trailer hitch, comprising a ball neck, which is movable between an operative position and a rest position and has a trailer ball, a pivot bearing unit, which is arranged fixed to the vehicle, and a rotation-blocking device having at least two rotation-blocking bodies that are guided such that they are movable by means of a guide body in a guide direction having at least one component in the radial direction in relation to the pivot axis, and having an actuation body, which is arranged such that it is rotatable about the pivot axis and has a respective wedge face extending transversely to the guide direction for each of the rotation-blocking bodies and of which the rotary movement in an actuation direction causes the at least two rotation-blocking bodies to be movable and urgeable in the guide direction, wherein there is provided a release position latching device that, in a release position of the actuation body, is movable between a latch release position, which releases movement of the actuation body in relation to the guide body, and a latching position, which fixes the actuation body in relation to the guide body, and, at least in the release position of the actuation body, is urged in the direction of the latching position by a spring element.

To improve a trailer device for a motor vehicle, comprising a holding unit for a crossmember mountable on a vehicle body on the rear-end side thereof and a ball neck receiving body having a ball neck receptacle, into which an insertion portion of a ball neck carrying a coupling ball is insertable and fixable, wherein the ball neck receiving body is arranged mounted on the holding unit so as to be pivotable at least between a working position, in which a ball neck is insertable by means of its insertion portion into the ball neck receptacle, and a rest position, it is proposed that the trailer device comprises a drive, which is coupled to the ball neck receiving body by means of a coupling unit which has a freewheel and which in particular comprises a plurality of coupling elements.

To improve a trailer device for motor vehicles, comprising a holding unit for a crossmember mountable on a vehicle body on the rear-end side thereof and a ball neck receiving body having a ball neck receptacle, in which an insertion portion of a ball neck supporting a coupling ball is insertable and fixable therein, wherein the ball neck receiving body is arranged mounted on the holding unit so as to be pivotable at least between a working position, in which a ball neck is insertable by means of its insertion portion into the ball neck receptacle, and a rest position, it is proposed that the trailer device comprises a locking device which fixes the ball neck receiving body in the rest position in a locking state relative to the holding unit and has an unlocking state, in which the locking device allows the ball neck receiving body to pivot from the rest position in the direction towards the working position, and that an actuator is provided, by means of which the locking device is movable from the locking state into the unlocking state.

A stowable stacked receiver has a fixed drawbar portion that allows affixation to a towing vehicle. Attached to the fixed drawbar portion is a movable stacked receiver that can pivot between a use and a stowed position. In the use position, the stacked receivers can receive a removable drawbar in a plurality of positions, and the stacked receivers are adjacent a flat surface on the fixed drawbar portion. In the stowed position, the stacked receivers are located underneath the fixed drawbar portion. A locking pin can be used to secure the movable stacked receiver in either the use or stowed position.

A folding trailer hitch is provided. The hitch includes a pair of bracket sidewalls each having two parallel columns of indexing holes. A hitch plate is included having a ball mount portion and an indexing portion. The indexing portion includes an upper indexing channel extending from an upper opening in a first side of the indexing portion to an upper opening in a second side of the indexing portion. The indexing portion also includes a lower indexing channel parallel to the first indexing channel and extending from a lower opening in a first side of the indexing portion to a lower opening in a second side of the indexing portion.

A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a T-shaped ballast coupled to the frame, and oriented such that the weight of the ballast is biased toward the front end of the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame, pivotable from a deployed state to an undeployed state; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein said brake system may be locked and unlocked and wherein the vehicle is provided with an on-board mechanism for locking and unlocking the brake system.

A rear arrangement for a vehicle includes a trailer coupling mount and a rear diffuser having an adjustable air-guiding element which is adjustable between a retracted position and an extended position. The trailer coupling mount is pivotable about a pivot axis, which is congruent or parallel to the vehicle transverse axis (y), between an inoperative position and a use position. The air-guiding element in the retracted position at least partially conceals the trailer coupling mount, and the air-guiding element has to be brought into the extended position so that the trailer coupling mount can be pivoted into the use position.
