[Prior Art] In such a driven pulley device, since the torque cam mechanism can correspond to the relative rotational phase difference between the movable pulley half and the fixed pulley half, an axial force acts on the movable belt On the wheel, the coil spring compressed between the movable pulley and the spring seat member generates torsion. Such torsion will produce a reaction force on the above-mentioned axial force, so that the movable pulley half presses the side of the V-belt. The pressure is unstable and generates vibration. Therefore, in the type disclosed in Patent Document 1, between the movable pulley and the coil spring, and the spring 5 312XP / Invention Specification (Supplement) / 94-08 / 94]] 222] 200538656 between the seat member and the coil spring At least one of the spaces is provided with a plate-shaped bearing so that the coil spring is not twisted. (Patent Document 1) Japanese Patent Laid-Open Publication No. 8-4 2 6 5 5 [Summary of the Invention] (Problems to be Solved by the Invention) However, a coil spring is not only prone to torsion as described above, but is also prone to partial eccentricity ' A wobble phenomenon occurs on the circumferential surface. If a wobble phenomenon occurs, the coil spring comes into contact with surrounding members and generates a strange sound. However, in the above-mentioned conventional types, it is impossible to prevent the coil spring from wobbling. The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a V-belt type automatic transmission which can prevent not only the torsion of a coil spring, but also a swing phenomenon.

各防音材1 3 7至1 4 0通過胺曱酸乙酯片的截斷成形，分 別呈編帶狀，這些防音材1 3 7至1 4 0的一個面通過黏接劑， 黏接於變速箱7 1和防音蓋1 2 9中的任意者上，在本實施例 中，黏接於防音蓋1 2 9的内面上。 下面對本實施例的作用進行描述，在V型皮帶式自動變 速機Μ的從動帶輪裝置7 9中，在活動帶輪半體9 0側，至 少螺旋彈簧9 3的内周由導引構件1 0 6導引，在彈簧座構件 9 2和螺旋彈簧9 3之間，設置推力軸承手段1 0 7，由此，可 使螺旋彈簧9 3與活動帶輪半體9 0 —起旋轉，以便不產生 相對活動帶輪半體9 0的旋轉，可防止螺旋彈簧9 3產生扭 轉。另外，由於在活動帶輪半體9 0側，螺旋彈簧9 3的内 周由導引構件1 0 6導引，故可防止在活動帶輪9 0側，螺旋 彈簧9 3發生擺動的現象，以便對螺旋彈簧9 3的内周進行 對中。 特別是對應於活動帶輪半體9 0的軸向移動，螺旋彈簧 9 3中的活動帶輪半體9 0側的半部的動作量較大，通過導 引構件1 0 6物件如此動作量較大的一側的内周進行導引， 20 312ΧΡ/發明說明書(補件)/94-08/94112221 200538656 由此，可更加有效地防止產生擺動現象的情況。 另夕卜，由於推力軸承手段1 0 7按照相互重疊的一對軸承 構件1 1 5，1 1 6夾持於螺旋彈簧9 3和彈簧座構件9 2之間的 方式構成，可由極簡單的結構，構成推力軸承手段1 〇 7， 另外，兩個軸承構件1 1 5，1 1 6由本身潤滑性樹脂形成，故 即使在送入容納室7 0的冷卻空氣包含灰塵的情況下，仍可 提高對灰塵的耐磨耗性。 此外，上述導引構件1 0 6也由本身潤滑性樹脂形成，由 ® 此，可使活動帶輪半體9 0側的螺旋彈簧9 3的内周和導引 構件1 0 6之間的滑動良好。其結果是，可將螺旋彈簧9 3 和導引構件1 0 6之間的間隙設定得盡可能地小，可更加有 效地防止螺旋彈簧9 3產生擺動現象的情況，可提高動作 性〇Each soundproofing material 1 37 to 1 40 is formed by cutting the urethane sheet into a braid shape. One surface of these soundproofing materials 1 37 to 1 40 is adhered to the gearbox through an adhesive. Any of 71 and the soundproof cover 1 2 9 is adhered to the inner surface of the soundproof cover 1 2 9 in this embodiment. The function of this embodiment will be described below. In the driven pulley device 79 of the V-belt automatic transmission M, at the side of the movable pulley half 90, at least the inner periphery of the coil spring 93 is guided by the guide member. 1 0 6 guide, a thrust bearing means 10 7 is provided between the spring seat member 92 and the coil spring 93, so that the coil spring 9 3 and the movable pulley half 90 can be rotated together so that The rotation of the movable pulley half 90 is not generated, and the torsion of the coil spring 93 can be prevented. In addition, since the inner periphery of the coil spring 93 is guided by the guide member 106 on the movable pulley half 90 side, it is possible to prevent the coil spring 93 from swinging on the movable pulley 90 side. In order to center the inner periphery of the coil spring 93. Especially in response to the axial movement of the movable pulley half body 90, the amount of movement of the half of the movable pulley half body 90 side of the coil spring 93 is large, and the amount of movement of the object by the guide member 106 The inner circumference of the larger side is guided. 20 312XP / Invention Manual (Supplement) / 94-08 / 94112221 200538656 As a result, it is possible to more effectively prevent the occurrence of swinging. In addition, since the thrust bearing means 1 07 is constituted by a pair of bearing members 1 1 5 and 1 1 6 which are overlapped with each other and sandwiched between the coil spring 9 3 and the spring seat member 9 2, it can have a very simple structure. The thrust bearing means 1 〇7 is formed. In addition, the two bearing members 1 15 and 1 16 are formed of a lubricating resin itself, so even if the cooling air sent into the accommodating chamber 70 contains dust, it can still be improved. Abrasion resistance to dust. In addition, the above-mentioned guide member 106 is also formed of a lubricating resin per se. As a result, the inner periphery of the coil spring 9 3 on the movable pulley half 90 side and the guide member 106 can slide. good. As a result, the gap between the coil spring 9 3 and the guide member 106 can be set as small as possible, and it is possible to more effectively prevent the coil spring 9 3 from swinging, thereby improving the operability.
還有，由於在活動帶輪半體9 0和外筒8 8，與在活動帶 輪半體9 0側，支承螺旋彈簧9 3的端面的導引構件1 0 6之 間，設置金屬製的軸環1 1 0，故可將導引構件1 0 6的厚度 設定得較小，可容易進行伴隨作為樹脂形成的導引構件 1 0 6的熱膨脹而產生的螺旋彈簧9 3的内周的間隙管理，另 外，可保持與彈簧座構件9 2側的摩擦係數的差異，可在螺 旋彈簧9 3和彈簧座構件9 2之間，更加確實地產生相對轉 動。 另外，由於變速箱7 1，與覆蓋該變速箱7 1的外側面， 安裝於變速箱7 1上的防音蓋1 2 9之間的空間通過防音材 1 3 7至1 4 0，而劃分為多個封閉空間1 3 4至1 3 6，故通過設 21 312XP/發明說明書(補件)/94-08/941 ] 2221 200538656 置於變速箱7 1和防音蓋1 2 9之間的防音材1 3 7至1 4 0吸收 的方式，抑制從變速箱7 1排放的噪音，通過防止在形成於 變速箱7 1和防音蓋1 2 9之間的封閉空間1 3 4至1 3 6，產生 聲音的共鳴的方式，抑制上述噪音，通過防音材1 3 7至 1 4 0，將變速箱7 1和防音蓋1 2 9之間的空間劃分為多個封 閉空間1 3 4至1 3 6，通過上述如此的簡單的結構，可獲得 充分的噪音防止效果。Further, since the movable pulley half 90 and the outer cylinder 88 are provided between the movable pulley half 90 and the guide member 106 which supports the end surface of the coil spring 93 in the movable pulley half 90, a metal Since the collar 1 1 0, the thickness of the guide member 106 can be set small, and the clearance of the inner periphery of the coil spring 9 3 caused by the thermal expansion of the guide member 106 formed as a resin can be easily performed. In addition, the difference in friction coefficient from the spring seat member 92 side can be maintained, and relative rotation can be more reliably generated between the coil spring 93 and the spring seat member 92. In addition, since the space between the transmission case 71 and the soundproof cover 1 2 9 installed on the transmission case 7 1 covers the outer side of the transmission case 71, it is divided into sound insulation materials 1 3 7 to 1 40. Multiple closed spaces 1 3 4 to 1 3 6, so by setting 21 312XP / Invention Specification (Supplement) / 94-08 / 941] 2221 200538656 Soundproofing material placed between the gearbox 7 1 and the soundproof cover 1 2 9 1 3 7 to 1 4 0 absorbs the noise emitted from the transmission 7 1 by preventing the closed space 1 3 4 to 1 3 6 formed between the transmission 7 1 and the soundproof cover 1 2 9 The way of sound resonance, to suppress the above noise, divide the space between the gearbox 7 1 and the soundproof cover 1 2 9 into multiple closed spaces 1 3 4 to 1 3 6 through soundproof materials 1 37 to 1 40. With such a simple structure, a sufficient noise prevention effect can be obtained.
