Description

装着孔23の内周面230には、軸心Oに沿って、溝深さd1が一定のガイド溝231と、上面20側から下面21側に向かうに従い溝深さd2が浅くなるテーパ付ガイド溝232とが、円周方向に等間隔で交互に複数形成されている。ガイド溝231およびテーパ付ガイド溝232には、滑り軸受3の後述するロワーケース31の回止め314が挿入される。これにより、ロワーケース31がスプリングシート2の載置面200に対して回転するのを防止して、ロワーケース31およびスプリングシート2が両者間の摺動によって摩耗するのを防止することができる。また、テーパ付ガイド溝232に挿入された回止め314がテーパ付ガイド溝232に対してシメシロとなることにより、ロワーケース31がスプリングシート2に固定して、スプリングシート2および滑り軸受3間のガタつきによる異音の発生を防止することができる。なお、図2では、一部のガイド溝231、テーパ付ガイド溝232にのみ符号を付している。 The inner peripheral surface 230 of the mounting hole 23 has a guide groove 231 having a constant groove depth d1 along the axis O, and a tapered guide in which the groove depth d2 becomes shallower from the upper surface 20 to the lower surface 21 . A plurality of grooves 232 are formed alternately at equal intervals in the circumferential direction. In the guide groove 231 and the tapered guide groove 232, a rotation stopper 314 of the lower case 31 of the slide bearing 3 described later is inserted. Accordingly, the lower case 31 is prevented from rotating with respect to the mounting surface 200 of the spring seat 2, and the lower case 31 and the spring seat 2 can be prevented from being worn due to sliding between them. Further, the rotation stopper 314 inserted into the tapered guide groove 232 is squeezed with respect to the tapered guide groove 232, so that the lower case 31 is fixed to the spring seat 2, and between the spring seat 2 and the slide bearing 3. Generation of abnormal noise due to rattling can be prevented. In FIG. 2, only some of the guide grooves 231 and the tapered guide grooves 232 are denoted by reference numerals.

図示するように、滑り軸受3は、環状のアッパーケース30と、ストラット式サスペンション4を構成するショックアブソーバ41のピストンロッド40が挿入されるとともに、アッパーケース30と回動自在に組み合わされる筒状のロワーケース31と、アッパーケース30とロワーケース31との間に配置された環状のセンタープレート32および金属ワッシャ33と、を備えている。 As shown in the drawing, the sliding bearing 3 has a cylindrical upper case 30 into which a piston rod 40 of a shock absorber 41 constituting the strut type suspension 4 is inserted, and which is rotatably combined with the upper case 30 . The lower case 31 includes an annular center plate 32 and a metal washer 33 disposed between the upper case 30 and the lower case 31.

アッパーケース30は、ガラス入りポリアミド樹脂等の強度の高い熱可塑性樹脂で形成され、その上面300には、ストラット式サスペンション4を車体に取り付けるためのアッパーマウント5(図4参照)への取付面301が形成されている。また、アッパーケース30の下面302には、金属ワッシャ33を装着するための装着孔303が上面300を貫いて形成されており、下面302の装着孔303の周囲には、金属ワッシャ33の上面330と接触する環状下面304が形成されている。 The upper case 30 is formed of a high-strength thermoplastic resin such as a polyamide resin containing glass, and has on its upper surface 300 a mounting surface 301 for mounting the strut type suspension 4 to an upper mount 5 (see FIG. 4) for mounting on the vehicle body. Are formed. A mounting hole 303 for mounting the metal washer 33 is formed in the lower surface 302 of the upper case 30 so as to pass through the upper surface 300, and the upper surface 330 of the metal washer 33 is formed around the mounting hole 303 of the lower surface 302. An annular lower surface 304 is formed in contact with the lower surface.

金属ワッシャ33は、アッパーケース30の環状下面304とセンタープレート32の上面320との間に配置され、ストラット式サスペンション4を構成するショックアブソーバ41のピストンロッド40が挿入される。金属ワッシャ33は、鋼、ステンレス等の鋼板、あるいは銅合金、チタン合金等の非鉄合金板で形成され、その上面330には、アッパーケース30の装着孔303に装着される筒状のボス部331が形成されている。 The metal washer 33 is disposed between the annular lower surface 304 of the upper case 30 and the upper surface 320 of the center plate 32, and the piston rod 40 of the shock absorber 41 constituting the strut suspension 4 is inserted therein. The metal washer 33 is formed of a steel plate such as steel or stainless steel, or a non-ferrous alloy plate such as a copper alloy or a titanium alloy, and has on its upper surface 330 a cylindrical boss 331 that is mounted in the mounting hole 303 of the upper case 30. Are formed.

また、本実施の形態では、スプリングシート2の装着孔23の内周面230に、軸心Oに沿って、溝深さd1が一定のガイド溝231と、上面20側から下面21側に向かうに従い溝深さd2が浅くなるテーパ付ガイド溝232とを、円周方向に等間隔で交互に複数設け、これらのガイド溝231およびテーパ付ガイド溝232に、滑り軸受3のロワーケース31の回止め314を挿入している。これにより、本実施の形態によれば、ロワーケース31がスプリングシート2の載置面200に対して回転するのを防止して、ロワーケース31およびスプリングシート2が両者間の摺動によって摩耗するのを防止することができる。また、テーパ付ガイド溝232に挿入された回止め314がテーパ付ガイド溝232に対してシメシロとなることにより、ロワーケース31をスプリングシート2に固定して、スプリングシート2および滑り軸受3間のガタつきによる異音の発生を防止することができる。 Further, in the present embodiment, a guide groove 231 having a constant groove depth d1 is formed along the axis O on the inner peripheral surface 230 of the mounting hole 23 of the spring seat 2, and goes from the upper surface 20 side to the lower surface 21 side . And a plurality of tapered guide grooves 232 of which the groove depth d2 becomes shallower in the circumferential direction are alternately provided at equal intervals in the circumferential direction. A stop 314 has been inserted. Thus, according to the present embodiment, the lower case 31 is prevented from rotating with respect to the mounting surface 200 of the spring seat 2, and the lower case 31 and the spring seat 2 are worn by sliding between them. Can be prevented. In addition, the rotation stopper 314 inserted into the tapered guide groove 232 is squeezed with respect to the tapered guide groove 232, thereby fixing the lower case 31 to the spring seat 2 and allowing the lower case 31 to move between the spring seat 2 and the slide bearing 3. Generation of abnormal noise due to rattling can be prevented.

また、上記の実施の形態では、滑り軸受のロワーケース31とスプリングシート2とを別体としているが、これらを一体的に形成してもよい。
Further, in the above embodiment, the lower case 31 of the sliding bearing 3 and the spring seat 2 are separate bodies, but they may be integrally formed.
