Description
Technical field
The present invention relates to the bounce limiter that a kind of suspension arrangement is used, this bounce limiter is to be used for vibration damper and the helical spring bounce limiter as the polyurethane foam system of the tubular on the suspension arrangement of the vehicle of constituting component, is particularly a kind ofly preventing characteristic bounce limiter on the technological means of noise.
Background technique
In the past, on the suspension arrangement as the vehicle of constituting component, use when spring and the cylinder butt of vibration damper limits the bounce limiter of the excessive contraction displacement of vibration damper with vibration damper and helical spring.
Its integral body of this bounce limiter is tubular and is installed into the piston rod that makes vibration damper and penetrates state in its center hole.
This bounce limiter, when vehicle bounces, the cylinder butt of its underpart and vibration damper also carries out the pressure elasticity distortion, the excessive contraction displacement of restriction vibration damper when absorbing impact, at this moment, when promptly carrying out the pressure elasticity distortion in the underpart, cylinder produces friction relatively, at this moment, there is the problem that is called " creaking (ギ ユ Star) " so undesirable noise (stick slip sound) that produces.
In the disclosed scheme of Japanese kokai publication hei 8-42624 communique, on the lower end surface of the bounce limiter of rubber system, a plurality of big projections to be set as the countermeasure that addresses the above problem.
But, a plurality of so big projections only are set on the lower end surface of bounce limiter, be inadequate to the generation that prevents noise.
Particularly in occasion as the bounce limiter of the polyurethane system of object of the present invention, compare with the bounce limiter of rubber system, with the cylinder butt time, its butt position has the local more character of easy deformation, in the process that big projection is crushed, noise will be produced, desirable countermeasure can not be become.
In addition, the bounce limiter of this polyurethane foam system is at underpart and cylinder butt and be out of shape when providing constraints simultaneously, the outer circumferential face that has its lower end surface not only but also a underpart can not address this problem with the disclosed scheme of Japanese kokai publication hei 8-42624 communique also with respect to the cylinder butt and produce friction and produce the problem of noise.
But, on candle formula independent suspension device, in the past, piston rod, the installation accessory of bounce limiters such as spring seat that bears helical spring upper end and upper end portion remain in the state that bounce limiter on this installation accessory is assembled into the one rotation mutually with chimeric status, in this case, bounce limiter makes the inner peripheral surface of its center hole with respect to the chimeric one-tenth contact condition of piston rod.
Because bounce limiter and piston rod are rotated motion integratedly, can not go wrong even do so also.
In contrast, a kind of like this suspension arrangement has been proposed, this suspension arrangement be by bearing with piston rod and bounce limiter etc. be assembled into piston rod with respect to above-mentioned installation accessory, promptly also with respect to chimeric remain on this installation accessory bounce limiter also independently the rotation state, in this case, when piston rod is rotated motion with respect to the inner peripheral surface of the center hole of bounce limiter around its axle center, produce friction herein, thereby also have the problem that produces noise herein.
In addition, occasion at candle formula independent suspension device, with connect piston rod to the line (turning to the vertical pin axis) of the assembly department of installing on the car body (upper end portion of piston rod by bearing fixing on vehicle body) and the cup-and-ball joint of knuckle that combines the fixing lower end of cylinder and underarm tip portion as center of rotation, underpart at cylinder is rotated on the basis of motion with wheel, promptly in the fixed-site of the upper end portion of piston rod, the underpart of cylinder is rotated motion and goes forward side by side on the basis that line position moves, when bounce limiter is in the counterrotating state of piston rod energy, when turning to and when vibration damper integral body is carried out rotational motion, piston rod moves to prizing direction with respect to the inner peripheral surface of the center hole of bounce limiter.
At this moment, preferably the center hole of bounce limiter is made from the upper end, the input that prizes is not added on the inner peripheral surface of center hole of bounce limiter from piston rod to the taper of lower end enlarged.
But when doing like this, the underpart of bounce limiter becomes thin-walled (wall thickness radially) and easy deformation, and is accompanied by its big distortion and more is easy to generate friction, therefore, has produced the problem that more is easy to generate noise herein.
Be very easy to produce this problem with respect to accessory is installed on promptly with respect to the suspension arrangement of the counterrotating form of bounce limiter at piston rod, but on the suspension arrangement of in addition form, also produce this problem sometimes.
In addition, no matter be the form that bounce limiter and piston rod rotate integratedly, still the form of separate rotation separately, bounce limiter in the past is when the braking action in when spring and when carrying out compressive strain in the axial direction, be entrenched in the upper end portion in the recessed embedding part that accessory is installed, at length saying, is that inner peripheral surface and the upper bottom surface in the recessed embedding part of the outer circumferential face of upper end portion and upper-end surface and installation accessory produces friction, also exists in the problem that noise takes place herein.
