Description
本創作係有關於一種鼓式煞車蹄片結構，尤其是指一種裝設於機車煞車機構中，並能與煞車機構內之煞車鼓磨擦而產生煞車作用之鼓式煞車蹄片。The present invention relates to a drum type brake shoe structure, and more particularly to a drum type brake shoe which is installed in a brake mechanism of a locomotive and which can be rubbed by a brake drum in the brake mechanism to generate a brake effect.
目前常見於機車的煞車系統大致可分為鼓式煞車系統與蝶式煞車系統。其中，鼓式煞車系統主要係將二相對應的煞車蹄片組設於輪轂中，所述煞車蹄片的一端形成一銷連接部，煞車蹄片另一端形成一凸輪連接部，並以銷連接部抵接煞車系統中之銷，以凸輪連接部抵接煞車系統中之凸輪，並於二煞車蹄片二端之間跨接彈簧，於煞車時，利用被帶動旋轉的凸輪推抵二煞車蹄片之凸輪連接部，使二煞車蹄片以銷連接部抵接煞車系統中之銷處為軸而令凸輪連接部朝外移動，且以二煞車蹄片之外緣壁所設的煞車材接觸輪轂磨擦而產生煞車作用。At present, the brake system commonly found in locomotives can be roughly divided into a drum brake system and a butterfly brake system. The drum brake system mainly comprises two corresponding brake shoes assembled in the hub, one end of the brake shoe forms a pin connection portion, and the other end of the brake shoe forms a cam connection portion and is connected by a pin. The part abuts the pin in the brake system, the cam connection part abuts the cam in the brake system, and the spring is bridged between the two ends of the second car shoe, and the braked cam is used to push the second car hoe during the braking The cam connecting portion of the piece is such that the two-way shoe piece abuts the pin in the braking system with the pin connecting portion as the shaft, and the cam connecting portion moves outward, and contacts the brake material provided on the outer edge wall of the two-way shoe piece The wheel hub is rubbed to create a brake effect.
碟式煞車系統由煞車盤和煞車鉗組成。該煞車盤與車輪同軸旋轉，煞車鉗橫跨在煞車盤的兩側呈固定不旋轉形成「鉗式」。煞車時，利用煞車鉗夾住煞車盤的兩側盤面，使煞車鉗上鑲嵌的摩擦片與煞車盤摩擦，迫使煞車盤轉速降低直至停止。The disc brake system consists of a brake disc and a caliper. The brake disc rotates coaxially with the wheel, and the brake tongs are fixed and non-rotated across the sides of the brake disc to form a "clamp". When braking, use the brake tongs to clamp the two sides of the brake disc, so that the friction plate embedded on the brake caliper rubs against the brake disc, forcing the brake disc speed to decrease until it stops.
整體上，蝶式煞車系統的優點為散熱快、調整方便，在高負載時耐高溫性能好，煞車效果穩定，但缺點是製造成本高；反觀鼓式煞車系統的優點則是製造成本低，但缺點卻是散熱效果不佳，容易在煞車過程中聚集大量熱能，使煞車蹄片和輪轂在高溫影響下產生變形，造成煞車振抖現象，以致於煞車效率下降。然而，在成本的考量下，鼓式煞車系統仍為一般車輛之煞車系統的首選。Overall, the butterfly brake system has the advantages of fast heat dissipation, convenient adjustment, high temperature resistance at high load, stable braking effect, but the disadvantage is high manufacturing cost; the advantage of the drum brake system is that the manufacturing cost is low, but The shortcoming is that the heat dissipation effect is not good, and it is easy to gather a large amount of heat energy in the process of braking, so that the brake shoes and the hub are deformed under the influence of high temperature, causing the phenomenon of braking of the brakes, so that the efficiency of braking is reduced. However, under the consideration of cost, the drum brake system is still the first choice for the brake system of general vehicles.
今，本創作人即是鑒於上述鼓式煞車系統在實際的實施使用上因為散熱效果不佳所產生的缺失之處，而研創出本創作。Nowadays, this creator is in the light of the above-mentioned drum-type brake system in the actual implementation and use of the lack of heat dissipation, resulting in the creation of this creation.
本創作之主要目的，係提供一種鼓式煞車蹄片結構，係期望透過本創作之鼓式煞車蹄片結構創新設計，解決現有鼓式煞車蹄片散熱效果不佳導致變形的缺陷。The main purpose of this creation is to provide a drum-type shovel structure, which is expected to solve the defects of the existing drum-type shovel blade with poor heat dissipation effect through the innovative design of the drum-type shovel blade structure.
上述本創作之主要目的與功效，是由以下之具體技術手段所達成：The main purpose and effect of the above creations are achieved by the following specific technical means:
一種鼓式煞車蹄片結構，其包含一蹄片本體，所述蹄片本體的一端形成一用以抵接一車輛煞車系統之銷的銷連接部，所述蹄片本體的另一端形成一用以抵接所述車輛煞車系統之凸輪的凸輪連接部，所述蹄片本體具有圓弧形之外緣壁與圓弧形之內緣壁，於所述外緣壁與所述內緣壁之間具有銜接板，於所述銜接板上且鄰近所述銷連接部與所述凸輪連接部之處設有一組裝孔，所述組裝孔係供彈性元件跨接組設，所述煞車蹄片在二所述組裝孔之間的所述銜接板上形成多個貫穿的散熱孔。A drum type brake shoe structure comprising a shoe body, one end of the shoe body forming a pin connection portion for abutting a pin of a vehicle brake system, and the other end of the shoe body is formed Abutting a cam connecting portion of the cam of the vehicle braking system, the shoe body having a circular arc outer edge wall and a circular arc inner edge wall, the outer edge wall and the inner edge wall Having a connecting plate, and an assembly hole is disposed on the connecting plate adjacent to the pin connecting portion and the cam connecting portion, wherein the assembling hole is provided for the elastic member to be bridged, and the brake shoe is at A plurality of through holes are formed in the connecting plate between the assembly holes.
據此，當煞車蹄片在與煞車鼓摩擦進行煞車動作時，便能透過該些散熱孔的設立，使煞車蹄片與煞車鼓摩擦所產生之熱能，由該些散熱孔排出，令煞車蹄片能因此快速散熱，避免煞車蹄片因為摩擦煞車鼓所產生之高溫影響本身的結構強度與煞車效能。According to this, when the brake shoe is rubbed against the brake drum to perform the braking action, the heat dissipation holes generated by the friction shoe and the brake drum can be discharged through the heat dissipation holes, and the brake shoes are discharged. The film can be quickly dissipated, so as to avoid the structural strength and braking efficiency of the brake shoe due to the high temperature generated by the friction drum.

係將二蹄片本體（１）以銷連接部（１１）對接銷連接部（１１）、凸輪連接部（１２）對接凸輪連接部（１２）的方式置入輪轂（５）內部，且令二蹄片本體（１）之銷連接部（１１）同時抵接煞車系統之銷（２），而二蹄片本體（１）之凸輪連接部（１２）同時抵接煞車系統之凸輪（３），再於二蹄片本體（１）彼此對應端處的二組裝孔（１６）各供一彈性元件（４）的一端安裝組配，使彈性元件（４）跨接於二蹄片本體（１）之間，平常二蹄片本體（１）受彈性元件（４）的拉掣，而保持其外緣壁（１３）上的煞車材（６）與輪轂（５）之間留有間隙不接觸摩擦之狀態，此時未產生煞車作用。The two shoe body (1) is placed inside the hub (5) with the pin connecting portion (11) butting pin connecting portion (11) and the cam connecting portion (12) abutting the cam connecting portion (12), and The pin connecting portion (11) of the shoe body (1) simultaneously abuts the pin (2) of the braking system, and the cam connecting portion (12) of the second shoe body (1) simultaneously abuts the cam (3) of the braking system, Then, the two assembly holes (16) at the corresponding ends of the two shoe body (1) are respectively assembled and assembled at one end of an elastic member (4), so that the elastic member (4) is bridged to the two shoe body (1) Between the two, the main body (1) is pulled by the elastic member (4) while maintaining a gap between the brake material (6) and the hub (5) on the outer wall (13) without contact friction. In this state, no braking effect is generated at this time.
於操作煞車時，利用被帶動旋轉的凸輪（３）推抵二蹄片本體（１）之凸輪連接部（１２），使二蹄片本體（１）以銷連接部（１１）抵接煞車系統中之銷（２）處為軸而令凸輪連接部（１２）朝外移動，並以二蹄片本體（１）之外緣壁（１３）所設的煞車材（６）接觸輪轂（５）磨擦，而因此產生煞車作用。When the brake is being operated, the cam connecting portion (12) of the two shoe body (1) is pushed by the cam (3) that is driven to rotate, so that the two shoe body (1) abuts the braking system with the pin connecting portion (11). The pin (2) is the shaft and the cam connecting portion (12) is moved outward, and the brake material (6) provided by the outer edge wall (13) of the two shoe body (1) contacts the hub (5) Friction, and thus the brake effect.
而當蹄片本體（１）在與輪轂（５）摩擦進行煞車動作時，因摩擦產生的熱能，能透過該些散熱孔（１７）快速散熱，避免蹄片本體（１）因為摩擦輪轂（５）所產生之高溫影響本身的結構強度。When the shoe body (1) rubs against the hub (5) to perform the braking action, the heat generated by the friction can be quickly dissipated through the heat dissipation holes (17), thereby avoiding the shoe body (1) because of the friction hub (5) The high temperature produced affects the structural strength of itself.
