摘要: Various examples of systems, methods, and applications of variable stiffness springs are described. In one example, a variable stiffness joint apparatus can include a torsional spring; a variable stiffness mechanism comprising a self-locking mechanism and a linkage system, the self-locking mechanism comprising an auxiliary spring; and an actuator in communication with the auxiliary spring of the self-locking mechanism. When the actuator changes position, a force is applied to the auxiliary spring by the actuator and a stiffness is adjusted at an energy cost that is independent of the stiffness of the spring and the energy stored by the spring. In another example, a self-adjusting variable stiffness mechanism can include a compression spring. The energy stored by compressing the compression spring and the mechanism can self-adjust a stiffness to enable energy accumulation using a same maximal compression force which is not dependent on the energy accumulated in the spring.

摘要: A shock absorber and a transportation tool. The shock absorber includes a first rotating arm; a second rotating arm pivotally coupled to the first rotating arm; and a torsion bar spring having a first end coupled to the first rotating arm and a second end coupled to the second rotating arm, wherein an included angle between the first rotating arm and the rotating arm has a set value. The shock absorber has a simple structure and good shock absorption effect and adjustable stroke.

摘要: Provided is a vehicular holding device that, in an ON state, holds a vehicle component in a state where displacement of the vehicle component in an axial direction is restrained, and that, in an OFF state, holds the vehicle component in a state where displacement of the vehicle component in the axial direction is possible. The vehicular holding device includes at least one engagement part, a cam mechanism, and an axial direction restraining part. The at least one engagement part is at a position where the engagement part engages with an engaged part in the ON state, and is at a position where the engagement part is separated from the engaged part in the OFF state. The cam mechanism displaces the at least one engagement part from the OFF-state position to the ON-state position. The axial direction restraining part receives axial-direction force acting on the at least one engagement part.

摘要: A method includes, providing a tubular member (10) used for a hollow spring, and applying the compressive residual stress to at least a portion of an inner surface of the steel tube by applying the compressive force to at least a portion of an outer surface of the tubular member (10) from a circumferential direction, and a fatigue life of the tubular member (10) is prolonged by applying the compressive residual stress to the inner surface of the tubular member (10). Applying the force to the outer surface of the tubular member (10) includes pressing the tubular member (10) with a die (1). The die (1) has a pressing surface (1a) shaped such that the compressive force can be applied to at least the portion of the outer surface of the tubular member (10) from the circumferential direction.

摘要: Vehicle seat fixed to the floor of a cabin of a vehicle and which is able to absorb the impact of a passenger seated behind. It comprises at least two uprights (20) per backrest, these being positioned substantially vertically and engaged via a lower end (30) in the fixed framework (32) of the seat in such a way as to be releasable through upward translational movement so that they can disengage upward under the effect of an impact on a rear face, and are mounted with the ability to rotate about at least one fixed axis of the fixed framework (32) so as to be able to pivot forwards after becoming disengaged. At least one deliberate mechanical weak link positioned between each upright (20) and the framework (32) blocks the translational movement of the upright below a determined force corresponding to the impact. Application to aircraft seats.

摘要: A torsional spring that can be used as a joint adapted to transmit at torsion actuation with elastic response. The torsional spring relates to a compact torsional elastic element, provided with a linear torque characteristic which is also not affected by the direction of rotation. The torsional spring is capable of attaining a high transmissible torque relative to its weight and overall dimension.
