摘要: A front fork comprises a telescopic tube (1, 32) in which a damper cylinder (3) generates a damping force. The damper cylinder (3) comprises a guide sleeve (4) and a free piston (6) having an inner circumference which slides on the outer circumference of the guide sleeve (4) and an outer circumference which slides on the inner circumference of the damper cylinder (3). A lateral through-hole (11) formed in the guide sleeve (4) connects an auxiliary reservoir (R3) formed outside the damper cylinder (3) and an oil reservoir (R2) via a flow path (12) formed in the guide sleeve (4) according to the displacement position of the free piston (6), thereby reducing the number of seal members required to be fitted on the outer circumference of the free piston (6) and enabling the free piston (6) to slide smoothly even when the telescopic tube (1, 32) suffers a bending force.

摘要: When an actuator in an operational mechanical system having a short continuous operation time is operated using a small-capacity electric motor (MG), an electric motor is rotated in the range exceeding a rated capacity, and during traveling with a long continuous operation time, the electric motor is rotated at the rated capacity or less. A controller (C) determines, from a signal provided from mode sensors (5a, 12a), whether the construction machine is in a traveling mode or in a traveling halt operation mode. When it is determined that the construction machine is in the traveling halt operation mode, the controller (C) sets the construction machine to a high output setting in which the electric motor (MG) rotates in the rage exceeding the rated capacity. When the construction machine is in the normal traveling mode, the controller (C) sets the construction machine to a low output setting so that the electric motor rotates at the rated capacity or less.

摘要: A piston (8) of a fluid pressure shock absorber (D, D1) partitions a first fluid chamber (R1) and a second fluid chamber (R2) in a cylinder (5) filled with a fluid. A pipe member (3) inserted into a housing (2, 30) has a connection to one of the first fluid chamber (R1) and the second fluid chamber (R2). The housing (2, 30) and the pipe member (3) form a space (4) there-between that connects the other of the first fluid chamber (R1) and the second fluid chamber (R2) to the pipe member (3). The pipe member (3) and the space (4) form a long fluid path between the first fluid chamber (R1) and the second fluid chamber (R2). The shock absorber (D, D1) thereby generates a damping force proportional to the stroke speed of the piston (8).

摘要: In a front fork which is capable of adjusting a spring force of a suspension spring housed in a fork main body by driving a jack mechanism housed in the fork main body to raise and lower an upper end position of the suspension spring, the jack mechanism defines a pressure chamber by means of a cap member that closes an upper end opening of a vehicle body side tube and a piston member. By supplying and discharging a pressure oil to and from the pressure chamber, the piston member ascends and descends, thereby raising and lowering the upper end position of the suspension spring.

摘要: A damping force control device (1) for a shock absorber (Dn) interposed between a sprung member (Bn) and an unsprung member (Wn) of a vehicle (A) comprises a damping force varying mechanism (3) which supplements a minimum damping force (Fdn) that can be generated by the shock absorber (Dn) with a variable damping force (Fcn). The device (1) comprises a control portion (2) which calculates a deviation (εn) between a damping force target value (Fsn) and the minimum damping force (Fdn) (S207), and open-loop controls the damping force varying mechanism (3) using a variable damping force (Fcn) calculated on the basis of the deviation (εn) such that the damping force generated by the shock absorber (Dn) coincide with the damping force target value (Fsn) (S208-S212), thereby optimizing damping force control of the shock absorber (Dn), which has a non-linear damping characteristic.

摘要: In a strut type shock absorber (1), a lower cap (2) is welded onto an inner circumferential surface of an outer shell (3) at a step (16) formed in a retreated position from an axial tip of the outer shell (3). The axial tip of the outer shell (3) is welded onto the inner circumferential surface of a knuckle bracket (6) which holds the outer shell (3). Since welding of the lower cap (2) onto the outer shell (3) and welding of the knuckle bracket (6) onto the outer shell (3) are conducted at different positions, the lower cap (2) is welded onto the outer shell (3) without suffering from blowholes irrespective of the material forming the knuckle bracket (6), and as a result, a weld bead (17) having a high degree of air-tightness is formed.

摘要: A steering shaft (2) penetrates a head tube (1) fixed to a vehicle body (A) of a motorcycle. The steering shaft (2) is coupled to a front wheel and handlebars of the motorcycle. A linear damper of a double-rod type is enclosed in the steering shaft (2). When the steering shaft (2) rotates with respect to the vehicle body (A), a feed screw (12) engaged with a screw portion (11) on the outer circumference of one of the piston rods (6a, 6b) causes the linear damper to operate. By enclosing the linear damper in the steering shaft (2), a space for disposing the steering damping device can be minimized. The feed screw (12) converts a rotational displacement of the steering shaft (2) into an axial displacement of the piston rods (6a, 6b) such that a bending load does not act on the piston rods (6a, 6b).

摘要: A hydraulic cushion unit (1) is interposed between a frame and a rear wheel axle of a bicycle. A surplus hydraulic oil discharging passage (31a) discharges surplus hydraulic oil from the hydraulic cushion unit (1) to an accumulator (2) in contraction. A damping force generating valve (3) which maintains a closed state below a predetermined cracking pressure is disposed in the surplus hydraulic oil discharging passage (31a). A bypass passage (4) which bypasses the damping force generating valve (3) and a bypass valve (4) which opens and closes the bypass passage (L) are further provided. By closing the bypass valve (4) when pedaling of the bicycle is performed to start the bicycle, squatting of the bicycle is prevented while maintaining a shock absorbing function of the damping force generating valve (3).
