摘要： A vortex flow hydraulic shock absorber for damping relative displacement of two components comprising a piston provided with a fluid passage therethrough including a pair of vortex chambers formed in a movable valve body disposed between a pair of resilient annular discs in a valve chamber in the piston. The valve body moves against the force of the resilient annular discs in response to an increase in the pressure difference of the working fluid on opposite sides of the piston to positions in which the fluid is permitted to bypass one or both of the vortex chambers as it traverses the piston, thereby varying the damping force of the shock absorber.

摘要： The shock absorber having a piston reciprocatingly disposed in a cylinder and sized small enough to permit a compact construction. The piston defines therein a vortex chamber with a maximum radius. The vortex chamber communicates with fluid chambers defined in the shock absorber via vortex passages formed in the piston. The vortex passage extends in the ceiling or bottom of the piston and tangentially opens at the upper and lower plane periphery of the vortex chamber. By providing the vortex passages in the above-mentioned manner, the radius of the vortex chamber can be maximized in relation to the radius of the piston thus reducing the size of the piston and, in turn the shock absorber.

摘要： A shock absorber with improved shock absorbing characteristiscs has a piston in which a vortex chamber is formed. The vortex chamber communicates with upper and lower fluid chambers via communication passages. One of the communication passage opens to the vortex chamber tangentially to produce a vortex in the vortex chamber. Within the vortex chamber, a member is normally elastically urged to narrow the area through which the fluid flows. The member is responsive to the fluid pressure exceeding a predetermined value to move against the resilient force in the direction increasing the area allowing fluid flow. A bottom fitting of similar construction and function is also disclosed.

摘要： A vortex flow shock absorber includes a piston having a vortex chamber therein. The piston communicates with one fluid chamber defined in a absorber cylinder via a vortex chamber and with the other fluid chamber separated from the former by the piston via a flow restricting opening. One-way valve is provided in a piston rod which defines a fluid passage permitting one way flow of the fluid from the vortex chamber to one of the fluid chamber. The one-way valve is responsive to an excessive fluid pressure in the vortex chamber to relieve the fluid pressure exceeding a predetermined value. The piston and piston rod are attached together with pressure welding. This simplifies the assembling operation of the piston onto the piston rod.

摘要： The torsion beam for a suspension is formed of a hollow shaft having a cross section substantially of the shape of an inverted letter U. It, therefore, can be manufactured simply and is enabled to enjoy light weight and improved torsional rigidity. This torsional rigidity can be adjusted and the amount of offset of the joined parts of opposite wheel supporting members from the other component parts can be freely adjusted. The end plates are constructed of a plurality of mutually joined end plates and the torsion beam is joined by welding to the surface for mounting the beam after the end plates have been machined. Thus, the torsion beam type suspension is manufactured with a relatively simple equipment, with the result that cost of equipment and the cost of production are lowered. The torsion beam can be manufactured with increased simplicity by subjecting a flat plate to the steps for swelling, folding and joining opposed of the flat plate or superposing a first and a second plate severally formed in a structure having a cross section substantially of the shape of an inverted letter U.

摘要： An independent suspension provided with a knuckle for rotatably supporting a wheel thereon and a sub-knuckle member pivotally supported on the knuckle, the knuckle connected to the leading terminal of a lower arm through a first ball joint and the basal terminal part of the lower arm is attached to an automobile body. The leading terminal of an upper arm is connected to the sub-knuckle member through a second ball joint and the basal terminal part of the upper arm is attached to the automobile body side. The leading terminal of a control link attached to the automobile body side is connected to the knuckle member through a third ball joint. The axis which passes the centers of the first ball joint and the second ball joint constitutes itself a steering axis. The center of the third ball joint is offset relative to the point of intersection between the horizontal plane passing the third ball joint and the steering axis. As a result, the knuckle members are allowed to produce a swinging motion around the second ball joint as the center to change the camber angle of the wheel while the automobile body is being steered.
