A system for controlling tilting of two wheels of a vehicle, mechanically anchored to the chassis by a first and a second oscillating anchor arm is provided. The system has a first cylinder and a second cylinder suitable for being interposed between the chassis and the first and second oscillating anchor arms respectively. The first and second cylinders have respectively a first chamber and a second chamber with variable volume and containing a working fluid. Transfer of working fluid from the first to the second chamber results in an increase in the volume of the second chamber. Transfer of working fluid from the second to the first chamber results in an increase in the volume of the first chamber. A pipe connects the first and second chambers so that working fluid is alternately transferable from the first to the second chamber and from the second to the first chamber.

The motor vehicle (1) comprises at least one rear driving wheel (5) and two front steered wheels (7′, 7″). A tilting four bar linkage (11) allows the motor vehicle to perform a tilting movement, for example, when cornering. Support arms (21′, 21″) for front steered wheels (7′, 7″), which rotate around steering axes (21A′, 21A″) and are joined to each other by a steering bar (23), are associated with the tilting four bar linkage Each wheel is constrained to the respective support arm with the interposition of a suspension (33; 33″). A tilting locking device comprises a brake (53′, 53″) which locks the springing movement of the respective suspension and the tilting movement of the four bar linkage.

A vehicle with a base frame to which at least two sprung suspensions, in particular sprung wheel suspensions, for driven, non-driven, steerable or non-steerable contact elements, for example wheels, are attached which can be steered by means of a steering knuckle and are located on both sides of the longitudinal direction of travel, in each case transversely to the direction of travel, a tilt frame, tiltable in a tilt axis with respect to the base frame. A steering tube is rotatably attached to the tilt frame in the steering axis and automatically tilts with the tilt frame, at least one track rod connected to the track rod actuating element, and a linear or rotary track rod actuating element rotatable over a guide element. The track rod actuating element is displaced by tilting the tilt frame about the tilt axis and independently thereof by rotating the steering tube about the steering axis in such a way that the steerable contact element is given a steering movement by the track rod actuating element by means of the at least one track rod and no substantial change in the camber of the contact elements takes place during cornering, wherein the vehicle comprises at least one spring damper system which is suitable and provided for reducing a pendulum tilt of a tilt frame about the vertical zero position.

A vehicle includes a dual linkage assembly coupled to two front wheels and a fork. The dual linkage assembly includes arms coupled at pivot points. Each arm rotates independently at the pivot points and responds to force applied by the rider, such that both front wheels maintain contact with the ground. The vehicle further includes a lock assembly including a lever and a lock block coupled to the front fork, a first piece with a first notch coupled to one or more of the arms, and a second piece with a second notch coupled to a head tube. When locked, the lock block engages the first notch, preventing the dual linkage assembly from rotating, and engages the second notch, preventing the fork from rotating. The vehicle is then capable of standing upright without assistance from a rider or stand.

A leaning vehicle, including a vehicle body leaning left and right when the leaning vehicle turns left and right, respectively, left and right steerable front wheels that are each steerable by a turning manipulation input device, a rear wheel unsteerable by the turning manipulation input device, a lean actuator that causes the vehicle body to lean, and a control device configured to control the lean actuator. When the left and right steerable front wheels are steered in a first direction while the leaning vehicle is traveling straight backward with the vehicle body being upright, the lean actuator causes the leaning vehicle to turn in the first direction, with a front portion thereof moving farther in a second direction than a rear portion, such that the vehicle body kept upright, where the first and second directions are respectively one and the other of the left and right directions.

A traveling vehicle includes a vehicle body, a left swing part, a right swing part, and an interlocking link mechanism. The left swing part and the right swing part are supported on the vehicle body so as to be swingable in the up-down direction, respectively. A left support part supporting a left front wheel is provided on a front part of the left swing part so as to be rotatable about a left steering shaft. A right support part supporting a right front wheel is provided at a front part of the right swing part so as to be rotatable about a right steering shaft. The interlocking link mechanism rotates one of the left support part and the right support part in conjunction with the other. The interlocking link mechanism is provided between the left support part and the right support part.
