なしたものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc brake using a combination caliper that has excellent caliper manufacturability and can easily handle increases and decreases in brake capacity. Note that the combination caliper referred to in the present invention is one in which a plurality of divided parts are fastened together to form one caliper.
ブレーキ容量の大きなディスクブレーキは摩擦材を押圧
するアクチュエータ、例えばピストンをディスクの周方
向に複数配置し、それ等を一体のキャリパ内に組込む方
法が採られる。このタイプのディスクブレーキは一般に
マルチポット型と称されているが、ディスクロータを挾
み着ける対の摩擦材を対向アクチュエータで別々に押圧
するいわゆるアクチュエータ対向型のディスクブレーキ
において、ロータ周方向のアクチュエータ数を増やすと
、キャリパの寸法及び重量が非常に大きくなり、その鋳
造、機械加工、組立等が困難になる。Disc brakes with a large braking capacity employ a method in which a plurality of actuators for pressing a friction material, such as pistons, are arranged in the circumferential direction of the disc, and these are assembled into a single caliper. This type of disc brake is generally called a multi-pot type, but in a so-called actuator-opposed type disc brake, in which a pair of friction materials that sandwich the disc rotor are pressed separately by opposing actuators, the number of actuators in the rotor circumferential direction is Increasing the caliper greatly increases the size and weight of the caliper, making its casting, machining, assembly, etc. difficult.
例えば大型の産業用車輌等に装備するディスクブレーキ
の場合、キャリパの重量が１００ ＫＳＩを超すことも
充分に考えられ、このようなケースではキャリパの製作
性が極端に悪くなり、かつ製造コストも大きく上昇する
。For example, in the case of disc brakes installed on large industrial vehicles, it is quite possible that the weight of the caliper exceeds 100 KSI, and in such a case, the manufacturability of the caliper becomes extremely poor and the manufacturing cost increases. Rise.
また、従来のディスクブレーキは、キャリパに収めるア
クチュエータの数が決っているのでブレーキ容量を増減
させることができず、被装備車種等が狭い範囲に限定さ
れると云う欠点もある。In addition, conventional disc brakes have the disadvantage that the number of actuators housed in the caliper is fixed, so the brake capacity cannot be increased or decreased, and the types of vehicles equipped with them are limited to a narrow range.
なお、インナーキャリパとアウターキャリパを分割成形
し、それをボルト止めして１個のキャリパとする技術は
既に存在するが、大重量のキャリ量の変更は不可能であ
る。Although there is already a technique in which an inner caliper and an outer caliper are molded separately and then bolted together to form a single caliper, it is impossible to change the caliper amount due to the large weight.
そこで、この発明は、上述の間頃点を無くした組合せキ
ャリパ式のディスクブレーキを提供するものである。Therefore, the present invention provides a combination caliper type disc brake that eliminates the above-mentioned intermediate point.

る。The disc brake of this invention solves the above problem,
A symmetrical torque receiving surface is provided at the front and rear in the circumferential direction of the disk with reference to the radial axis of the disk, and the side surface of the back plate of the friction material comes into contact with the surface, and a disk passage groove is provided at the center of the surface in the axial direction of the disk. a pair of opposing cylinders that connect a plurality of torque receiving members arranged at a constant pitch in the circumferential direction of the disk and two adjacent torque receiving members arranged at a constant pitch in the circumferential direction of the disk at one end surface side and the other end surface side of the disk; An actuator for pressing the friction material built into each cylinder, a retention pin for the friction material suspended between the opposing cylinders, and an actuator inserted between adjacent torque receiving members with a disk in between, allowing the actuator to slide freely onto the retention pin. The two supported parts are composed of a pair of friction materials.
このように、１個のキャリパを複数の部品の組合せによ

重量を軽減でき、また、その２者とアクチュエータ摩擦
材及びその保持ピンはいずれも同−形状及び大きさであ
るのでそれぞれに同じ設備を利用して製造でき、従って
、生産性が非常に良くなり、しかも量産効果が生まれる
ため製造コストも減少する。In this way, by constructing one caliper by combining multiple parts, the weight of each torque receiving member and cylinder can be reduced, and the two parts, the actuator friction material, and its holding pin can all have the same shape. Because of their large size, they can be manufactured using the same equipment, resulting in very high productivity, and mass production effects, which reduce manufacturing costs.
また、トルク受け部材とシリンダの連結数を増減してブ
レーキ容量を変更することも可能になる。Furthermore, it is also possible to change the brake capacity by increasing or decreasing the number of connections between the torque receiving member and the cylinder.
さらに、トルク受け部材を２以上組合せる場合、周方向
に配列するシリンダ間のトルク受け部材は。Furthermore, when two or more torque receiving members are combined, the torque receiving members between the cylinders arranged in the circumferential direction are as follows.
対向摩擦材の２組のトルク受けに共通して利用するので
ブレーキの寸法が比較的小さく収まり、その設置スペー
スも小さくて済む。Since it is commonly used for two sets of torque receivers of opposing friction materials, the size of the brake can be kept relatively small, and the installation space can also be small.
以下に実施例を挙げる。この発明のブレーキは、トルク
受け部材の少なくとも２個をシリンダで連結すればよい

場合も、それ等が全て一体的につながって１個のキャリ
パとなる。The torque receiving member 1 has a symmetrical torque receiving surface 1a on the left and right sides (front and back in the circumferential direction of the disk) with respect to the radial axis C of the disk D, and has a torque receiving surface 1a at the center of the surface in the disk axial direction as shown in FIG. A disk passage groove 1b as shown is provided, and further,
A mounting part 1c for the fixing member is formed on one end surface side (inner side) of the disk bordering this groove, and both end surfaces in the axial direction of the disk are flat surfaces for cylinder connection. . These torque receiving members are arranged at a constant pitch in the circumferential direction of the disk as shown in FIG. 2 are connected to each other. Therefore, as shown in the figure, even when two or more torque receiving members are used, all of them are integrally connected to form one caliper.

てスライド自在に支持する。Next, the friction members 6 and 6' are assembled to each cylinder so that there is a slight gap between adjacent torque receiving members, and the retaining pin 5 suspended between the opposing cylinders is loosely inserted into the back plate. Supports sliding freely.
なお、図では対の摩擦材を１本の保持ピンで支持してい
るが、対向摩擦材の支持は複数の保持ピンを挿通して行
ってもよい。In addition, although the pair of friction materials are supported by one holding pin in the figure, the opposing friction materials may be supported by inserting a plurality of holding pins.
また、隣接のトルク受け部材にボルト止めしてキャリパ
外周部の開口を閉じるダストカバー９は、望ましいもの
ではあるが、必須のものではない。Further, the dust cover 9 that is bolted to an adjacent torque receiving member and closes the opening on the outer periphery of the caliper is desirable, but not essential.

作動液供給点を１個所に集約でき。Furthermore, the manner in which the hydraulic fluid is supplied to the hydraulic pressure chamber of each cylinder is not particularly limited. However, as in the example brake, there is a liquid inlet 11 in the torque receiving member 1 at one end, and a branch flow that passes from there to the inner end face and the outer end face and connects to a flow path 12 extending from the cylinder hydraulic pressure chamber at the end. Route 13 (
On the other hand, the remaining torque receiving members excluding the torque receiving member at the other end are provided with communication passages 14 for connecting the flow passages 12' leading to the hydraulic pressure chambers of the adjacent cylinders.
13 and 12' and 14 are connected through the seal ring 15, the hydraulic fluid supply points for the hydraulic pressure chambers of all cylinders can be concentrated at one location.

り製造コストも引下げられる。Since the caliper is constructed by combining multiple torque receiving members with symmetrical torque receiving surfaces and a single-pot cylinder that connects the adjacent torque receiving members on the inner and outer sides, the weight of the individual parts is reduced. is reduced. In addition, the torque receiving members, cylinders, pistons, friction materials, and their holding pins, which are used in multiple pieces, all have the same shape and size, so productivity is excellent, and manufacturing costs are reduced due to the mass production effect. .
また、アクチュエータの増減が可能なため、ブレーキ容
量も自由に変更できる。Additionally, since the number of actuators can be increased or decreased, the brake capacity can also be changed freely.
