Claims

200301805 六、申請專利範圍 1. 一種自動變速裝置，主要係由中空殼體形成一座體内依序裝設一傳輸裝置及一扭力回饋裝置所構成）·其特徵在於：~ 該座體具有穿透其殼體而分別形成三角狀之數個相互對應的導槽及形成平行環向之一長形溝槽，且該座體内底部及外底部分別形成一凸緣；該傳輸裝置係由一内齒輪結構形成之切換齒輪0i合一第一行星式齒輪組及一第二行星式齒輪組所構成，該第一行星式齒輪組具有一外齒輪，該切換齒輪外環周圍形成一内凹之環槽且外表底部形成配合該座體内底部之凸緣數個凹槽；該扭力回饋裝置具有一推力輪、一套環及一壓縮彈簧，該推力輪外表面向外延伸形成一導桿，該套環裝設有數個插梢可穿過該座體之各個導槽中而銜入前述切換齒輪之環槽中，且該套環配合該座體之溝槽及該推力輪之導桿而形成穿透且平行軸向之一長形開槽，該壓縮彈簧則係受該套環及座體外表面之凸緣而拘束在該座體外環周圍上；前述之各個導槽係一頂角朝上且一底邊平行環向並向兩側延伸適當距離而形成凹槽；— 前述之推力輪被轉動時，其導桿會沿著該座體之溝槽移動並透過該開槽而帶動該套環轉動，使得該套環會同時藉由其底部之插梢沿著該座體之溝槽的斜面下降而壓掣該壓縮彈簧產生軸向之抵抗力；前述之套環裝設有數個插梢可銜入該座體之各個導槽中而受其限制，該插梢並會銜入前述切換齒輪之環槽中，以拘束該切換齒輪處於第一極限位置而同時嚙合該第一行星式齒輪組200301805 6. Scope of patent application 1. An automatic transmission device, which is mainly composed of a hollow casing, a transmission device and a torque feedback device are sequentially installed in the body). Its characteristics are: Through the casing, a plurality of corresponding guide grooves in the shape of a triangle and an elongated groove in a parallel hoop are formed respectively, and a flange is formed on the bottom of the body and the bottom of the body respectively; the transmission device consists of a The switching gear formed by the internal gear structure is composed of a first planetary gear set and a second planetary gear set. The first planetary gear set has an external gear, and a concave recess is formed around the outer ring of the switching gear. The ring groove and the bottom of the outer surface form several grooves that match the flanges on the bottom of the body. The torque feedback device has a thrust wheel, a set of rings and a compression spring. The outer surface of the thrust wheel extends outward to form a guide rod. The collar is provided with a plurality of pins that can pass through the respective guide grooves of the base body and engage in the ring grooves of the aforementioned switching gear, and the collar is formed in cooperation with the groove of the base body and the guide rod of the thrust wheel. penetrate An elongated slot parallel to the axial direction, the compression spring is restrained around the outer ring of the seat by the collar and the flange on the outer surface of the seat; each of the aforementioned guide grooves has a top angle facing upward and a bottom The sides are parallel to the ring and extend an appropriate distance to both sides to form a groove;-When the aforementioned thrust wheel is rotated, its guide rod will move along the groove of the seat body and drive the collar through the slot, So that the collar will simultaneously press the compression spring to generate axial resistance by the bottom pins falling along the inclined surface of the groove of the base; the aforementioned collar is equipped with several pins that can be inserted into The guide grooves of the base body are restricted by them, and the pin will be engaged in the ring groove of the switching gear to restrain the switching gear from being in the first extreme position while engaging the first planetary gear set.
