An autonomous vehicle includes a frame with a motor, a bumper connected to the frame via a connecting device, and a sensor detecting displacement of the bumper upon a collision. The sensor is connected with a propulsion system that interrupts displacing the vehicle upon detecting a displacement. The connecting device includes a ring, a first ball part, a second ball part, a shaft, and a spring. The ring is fixedly connected to the frame, and the first and second ball part rotatably tilt in the ring. The shaft extends through the ring and the first ball part, and through and beyond the second ball part to a second end, at which the shaft is connected to the bumper by a joint. At least one ball part is displaceable along the shaft. The spring extends around the shaft between the second ball part and a spring connector, and pretensionedly presses the first and second ball parts against the ring. Upon a collision with an obstacle, the bumpers shifts, and the shaft tilts with respect to the frame. This tilting pushes the two ball parts away from each other. The spring also tilts, as a whole, preventing plastic deformation. The spring now exerts a larger spring force on the ball parts, and, after taking away the obstacle, will move back and realign. This will also realign the sensor, ensuring a longer effective lifetime of the sensor and thus of the safety of the vehicle.

A suspension system for a work vehicle includes a rear suspension assembly that includes a first shock absorber assembly and a second shock absorber assembly, such that each of the first and second shock absorber assemblies has a first end that couples to a cab of the work vehicle and a second end that couples to a chassis of the work vehicle. The rear suspension assembly further includes a brace extending laterally between the first end of the first shock absorber assembly and the first end of the second shock absorber assembly relative to a direction of travel of the work vehicle, such that the first end of the first shock absorber assembly and the first end of the second shock absorber assembly are coupled to the brace. In addition, the rear suspension assembly includes a longitudinal tie rod oriented substantially longitudinally along the direction of travel of the work vehicle, such that the longitudinal tie rod has a first end rotatably coupled to the brace and a second end configured to rotatably couple to the chassis of the work vehicle. The first end of the first shock absorber assembly and the first end of the second shock absorber assembly decouple from the cab without decoupling the brace from the first end of the first shock absorber assembly and the first end of the second shock absorber assembly.

The present disclosure includes a jounce bumper with a main body and an insert. The main body includes a first polymeric material. The insert is integral with the main body and includes a second polymeric material that is different from the first polymeric material. The insert further includes a first plate, a second plate, and a connecting lattice that connects the first plate and the second plate together. The first polymeric material of the main body is between the first plate and the second plate, and is within the connecting lattice.

A vehicle includes an aerodynamic mechanism for a vehicle including a body and a wheel. The aerodynamic mechanism includes a wing and a coupling assembly. The wing is configured to be arranged to intersect and airflow such that the airflow circulates about the wing and generates downforce. The coupling assembly is operatively connected to the wing and configured to be operatively connected to the body. The coupling assembly is configured to be selectively coupled to the wheel such that downforce generated by the wing is transmitted through the coupling assembly, directly to the wheel. The coupling assembly is configured to be selectively decoupled from the wheel such that downforce generated by the wing is transmitted through the coupling assembly, directly to the body.

A torsion device comprising: a first part comprising a first resilient torsion member including: a first support end; a first free end spaced from the first support end; and a first engagement region; a second part comprising a second resilient torsion member including: a second support end; a second free end spaced from the second support end; and a second engagement region; wherein the second part is rotatable relative to the first part about an axis of rotation (A) between a first angular position and a second angular position, and the first and second torsion members are configured to urge the first and second engagement regions together to cause flexure of at least one of the first and second resilient torsion members as the second part rotates relative to the first part from the first angular position to the second angular position.
