A steering axle for a steerable vehicle includes an axle housing, a steering motor, a steering gear, a first steering knuckle with a first steering arm, a second steering knuckle with a second steering arm, a coupling rod, a first tie rod, and a second tie rod. The first and second steering arms are each rigidly arranged on a respective steering knuckle that is hinged in the axle housing. The first and second tie rods are each hinged at a first end to a respective steering arm and hinged at a second end to the coupling rod. The steering axle is configured so that the steering motor can set a steering angle of the steering axle via the steering gear. The steering axle has first and second intermediate steering levers, each hinged at its first end to the axle body and hinged at its second end to the coupling rod.

A three-wheeled vehicle may include one rear wheel and two front wheels coupled to a tiltable chassis, such that tilting of the chassis causes a corresponding tilting of the three wheels. The tiltable chassis includes a tiltable body coupled to a non-tilting frame by a pair of rotatable joints, such that the tiltable body is configured to rotate relative to the frame. A fore-and-aft connecting beam of the tiltable body extends beneath the frame to accommodate a battery compartment or other storage on top of the frame. A front tower extends upward from a front end of the connecting beam, above the frame, to couple to a tilt linkage and seat post of the vehicle. A rear tower extends upward from a rear end of the connecting beam to retain the rear wheel.

An in-wheel motor unit coupling structure includes an in-wheel motor unit and a shock absorber. The in-wheel motor unit is disposed inside a wheel of a vehicle. The in-wheel motor unit is configured to support the wheel such that the wheel is rotatable. The in-wheel motor unit includes an electric motor that serves as a rotational driving source of the wheel. The shock absorber is coupled to the in-wheel motor unit. The shock absorber is a component of a vehicle suspension. A lower end portion of the shock absorber is fastened to a vehicle center side, in a vehicle width direction, of a motor part so as to be pressed against the motor part outward from the vehicle in the vehicle width direction. The motor part is a part in which the electric motor of the in-wheel motor unit is built.

A support structure for a vehicle includes: a body portion (22); a damper attachment portion (24); a tie-rod attachment portion (26); and a lower arm attachment portion (28). The vehicle supporting structure (20) has a first rib (32) that connects the damper attachment portion (24) with the tie-rod attachment portion (26), a second rib (34) that connects the tie-rod attachment portion (26) and the lower arm attachment portion (28), and a third rib (36) that connects the first rib with the second rib. The first rib is inclined to have a height that gradually decreases from the damper attachment portion toward the tie-rod attachment portion, forming a first inclined portion (32a) and a first thinned portion (32b). The third rib is inclined to have a height that gradually decreases from the second rib toward the first rib, forming a second inclined portion (36a) and a second thinned portion (36b).
