A pivotable trailer coupling unit aligns its axis through the ball head to manage angular shifts during operation.

A trailer device pivot bearing unit moves the ball neck receiving body between working and rest positions.

High-strength steel profiles replace thick welded sections in a trailer hitch cross member, reducing weight and eliminating thermal stress fractures.

A tow bar body combines open and closed orthogonal cross-sections along its longitudinal axis to provide accessible storage space.

Stacked linkages on a vertical pivot post enable independent rotation, accommodating vehicle twisting motion without structural failure.

A hitch angle module estimates orientation using a kinematic model and ultrasonic sensor inputs for precise trailer control.

A vehicle coupling device uses a rotary cap to pivot locking devices between locked and unlocked positions.

Rotary lugs with arc surfaces slide within skin grooves to shift the rotating axis position, eliminating interference during bumper opening.

Adjustable shank with friction-reducing rollers aligns with receiver, eliminating binding issues during heavy load engagement.

An interference peg rests in the socket to block T-bolt rotation, resolving reliability and complexity trade-offs for secure tie-downs.

Motorized extendable trailer mounts use threaded drive trains to position vehicles in water, eliminating manual maneuvering on steep inclines.

Replacing friction pads with air springs eliminates wear from rain and humidity while maintaining yaw oscillation control.

A rotatable ball mount apparatus uses a manual locking pin to switch between multiple hitch balls without tools.

Multiple bores distribute load across separate contact points, reducing vibration and swaying while allowing simultaneous trailer and accessory mounting.

A tow bar latch assembly uses a pivotable sear to lock telescopic bar elements in an extended configuration.

Concave housing apertures dispense grease onto tow balls while a seal prevents hand contamination.

Radial collar and groove system on towing bolt constrain safety bolt movement to prevent unintentional release.

A conveying device uses a sliding mechanism to move a connection part relative to a base member for carriage engagement.

A bearing swivel hitch rotates to accommodate pull angles while a composite recovery rope prevents binding during vehicle recovery operations.

A towbar ball joint uses an axial lock engaging form-fitting contours within a hollow member cavity to secure the ball rod.

A mechanical linkage system tensions spring arms through a trailer jack, resolving installation complexity while stabilizing sway.

Universal rail sockets enable quick conversion between hitch types while trim rings protect the vehicle bed from cargo damage.

Integrating multiple trailer connections into one housing reduces assembly effort and manufacturing costs by minimizing separate mounting operations.

U-shaped chain holder secures safety chains at a fixed height using inward projections and hook portions.

Segmented polygonal extruded hollow beam absorbs trailer loads while reducing manufacturing complexity.

A spring-loaded actuation ring locks the towing device coupling arm, eliminating manual tightening errors and ensuring consistent attachment force.

Spring-loaded clamping bar secures hitch balls in single-piece couplers, preventing disconnection during towing.

Segmented design and intermediary plunger enable easy interchange while preventing premature trailer socket connection.

A pivoting drawbar interlocks with a trailer chassis using a cam-driven latch for rapid single-operator assembly.

An angled support profile distributes impact energy across a wider area, reducing force peaks at connection points and preventing damage to welded joints.

Baseline electrical load measurement distinguishes theft from environmental changes, reducing false alarms in vehicle alarm systems.

Strain gauges on carrier ribs measure deformation to prevent damage from high shear loads, ensuring operational safety.

Swinging fixed members absorb rear-end collision energy via a cross member, preventing rear side frame deformation in battery vehicles.

Variable cross section design resolves weight stiffness trade off while ensuring crash energy absorption.

A common trailer connection merges brake and lighting supply lines into one socket, reducing cabling effort and installation costs.
