Abstract:
A three-wheeled vehicle (1) includes: a body frame; left and right front wheels (3); a link mechanism (30) configured to connect the left and right front wheels (3) with the body frame; a shock absorber (40) capable of damping vibrations in the same phase occurring in the left and right front wheels (3); and a damper (50) capable of damping vibrations in opposite phases occurring in the left and right front wheels (3) wherein the damper (50) is configured such that its damping force increases at least in a certain frequency range as the frequency of the vibrations in the opposite phases increases.
Abstract:
The invention relates to a valve device for an air suspension system in a motor vehicle. Said valve device has improved operational comfort. For this purpose: (a) said valve device (6) comprises an electric actuation assembly (7, 8, 21, 22) and a manual actuation element (9); (b) said valve device (6) has a pneumatically actuable operating valve assembly (27, 28, 29), said actuation enabling the aeration connection (14, 15) to be selectively connected to or separated from a reserve connection (18) or a ventilation connection (12); (c) said operating valve assembly (27, 28, 29) can be pneumatically actuated by either the electric actuation assembly (7, 8, 21, 22) or by a pneumatic valve assembly (23, 24, 25, 26) which can be actuated by the manual actuation element (9); (d) the manual actuation element (9) can be blocked in at least one position by an unlockable locking device (30); (e) said unlockable locking device (30) can be locked by actuating at least one part of the electric actuation assembly (7, 8, 21, 22).
Abstract:
A saddle riding type vehicle (1) includes a right rear arm (41R) and a left rear arm (41L) for supporting at least a pair of wheels (43) at opposite sides of a vehicle body to be movable up and down relative to the vehicle body, and a right hydraulic cylinder (71R) and a left hydraulic cylinder (71L) for operating the right rear arm and left rear arm to change a lean amount of the vehicle body. A controller (95) controls the right hydraulic cylinder and left hydraulic cylinder according to vehicle speed. Since the lean amount of the vehicle body can thereby be adjusted according to vehicle speed, both comfortable traveling performance and stability of the vehicle are ensured.
Abstract:
A wheelchair suspension that inhibits tipping of a wheelchair. The wheelchair suspension prevents upward movement of the front casters with respect to the frame and allows downward movement of the front casters when the wheelchair exhibits a tipping behavior. The wheelchair suspension also biases the front casters downward with respect to the frame when the wheelchair exhibits a tipping behavior.
