A forecarriage (8) of a rolling motor vehicle (4), comprising a forecarriage frame (16), at least a pair of front wheels (10), each wheel (10) being connected to a rolling kinematic mechanism (20), which enables the front wheels (10) to roll in a synchronous and specular manner, by means of a respective axle journal (60), and a roll block system (100) comprising a rod extensible in length (110) which directly connects one of the two front wheels (10) at the respective axle journal (60) to said forecarriage frame (16) by means of hinging means (71, 72, 73) at both its ends, and means (120) to reversibly block the lying position of said rod extensible in length (110) on a rolling plane with respect to said axle journal (60) and to said forecarriage frame (16), so as to block the rolling movements allowed by said rolling kinematic mechanism (20).

Embodiments of the present invention include to a two-tier structural frame for a three-wheeled cargo bike. The structural frame can be the platform for the entire bike and includes both steering and suspension parts. The frame of the bike and its related suspension and steering parts provide stability, durability, and comfort, while in motion under human pedal power, as well as motion from a hybrid of human pedal and electric-assisted power sources.

A structure of rocking controller of a saddle riding type vehicle includes a rocking lock mechanism configured to lock lateral rocking of the vehicle body; wherein the rocking lock mechanism includes an arc shaped lock plate which crosses with an axial direction of a rocking shaft of the vehicle body and a lock caliper configured to lock a relative rocking between the lock plate and the lock caliper by clamping the lock plate, and a motor for the actuator is arranged in front of the rocking lock mechanism and the rotating drive shaft of the motor is arranged so as to penetrate an inner circumferential region of the arc shaped lock plate.

A rolling motor vehicle (4) comprising a forecarriage frame (16), at least one pair of front wheels (10), a rolling kinematic mechanism (20) to which each wheel (10) is connected by means of a respective axle journal (60), a roll control system (100) comprising a rod (110) which connects the two front wheels (10) directly to each other at the respective axle journals (60), the roll movements of the two front wheels (10) and of the respective axle journals (60) causing changes in the lying position of said rod (110) with respect to a vertical projection plane which is transverse to a centre line plane of the motor vehicle (4), the rod (110) is usable directly or indirectly by the driver (P) as a command element to control the rolling movements of the two front wheels (10) without having to put his feet on the ground.

Automatic tilting vehicle is provided that includes left and right front wheels supported by knuckles, a rear wheel steered by a steering actuator, a vehicle tilting device, and a control unit. The control unit calculates a target tilt angle of the vehicle and a target steered angle of the rear wheel based on a steering angle and a vehicle speed, controls the vehicle tilting device so that a tilt angle of the vehicle becomes the target tilt angle, and controls the steering actuator so that a steered angle of the rear wheel becomes the target steered angle. When the vehicle is turning and decelerating, a steered angle of the rear wheel is controlled not to be the target steered angle but to zero, and a tilt angle of the vehicle is reduced by a gyro moment of the rear wheel.

A suspension group for a motor vehicle, wherein said suspension group includes: a wheel guide, which extends along a longitudinal axis, which includes a wheel attachment for connection to a rotation pin of a wheel having a rotation axis orthogonal to said longitudinal axis, wherein the wheel guide extends between a first end and a second end, opposite the first end, a support arm functionally connected to the wheel guide respectively by means of: a first crank rotatably connected at said second end to the wheel guide and to the support arm; a second crank rotatably connected at said first end to the wheel guide and to the support arm, wherein the wheel guide elements, the support arm and the first and second crank define a suspension quadrilateral, wherein, between at least two of said elements chosen between the wheel guide, the support arm, the first and the second crank, a shock absorber group is interconnected in such a way that the shock absorber group varies its extension as the movement of the suspension quadrilateral varies.

A modular, reconfigurable frame that can be combined into multiple standardized segments to create different core vehicle configurations is described herein. The frame includes a plurality of components that affix together universally to make multiple versions of cycle, vehicle, and airframe styles. The reconfigurable frame includes a quick pin and fastener that allows for transportation platforms to be incorporated into the frame in a modular fashion.
