Description of the Invention: [Technical Field] The present invention relates to a greedy member, and more particularly to an automatic centering hoisting member suitable for a counterweightless elevator. [Prior Art] It is known to use a flat yoke. The cabin of the component suspension elevator, for example by means of tensile ropes or wire r〇pes, reaches the internally reinforced belt. This built-in tension cord is made of a suitable high tensile material such as steel, carbon fiber or the like. An elevator hoisting member is disclosed in the patent of GB-A-13625, which has a plurality of steel cord seals in a plastic medium. In the ep_au53i67 patent, the tension member of the elevator system is disclosed, which comprises a body and a counterweight, and has an aspect ratio greater than -, wherein the aspect ratio is defined as the width of the tension member w versus the thickness t Ratio (w/t). The tension member comprises a plurality of metal carrier ropes enclosed in a conventional coating layer defining a bonding surface for bonding to the oxygen-bearing sheave. ...the flat W component of a modern lift usually prefers the use of a rope because the length of the pulley can be shortened. The wire is spread over the flat face member: instead of twisted into a rope. It should be noted that the applicable regulations :: will be: the ratio of the length of the wheel to the length of the rope is specified. If the traction member and the flat skin are not—the ropes, the pulley diameter can be longer than the car's father's consideration. ~τ~·, ..., the above-mentioned flat traction members are known to have the following technical problems, and the disadvantages have not been completely solved so far. 3 201111265 The first 'manufacturing process should ensure that the built-in wire or strand is on a flat surface and is located in the central region between the two surfaces of the flat traction member. This need complicates the production process, which means that a precise guidance must be provided for high tension wire or strands. In addition, it is necessary to reduce the weight and cost. This is especially important for low-cost elevators such as non-weighted, so-called home lifts (h〇meHft). Small, non-weighted lifts (home lifts) are particularly suitable for installation in residential homes and are usually used by a small number of people, just as their capacity is limited. However, its potential applications include the construction of new buildings and old buildings, which meet the needs of today's convenience, and it is also unlikely that the above-mentioned counterweight lifts will be installed. Furthermore, the reliability and durability of the traction members are also a problem. The built-in tension rope is easy to arrange in an arc shape due to contact with the pulley of the drive system during use. Because of A, the stress on the tension rope is not evenly hooked and may deviate from the pure trigger effect. Example # ' When a plastic flat belt with a built-in steel wire is in contact with a --slide wheel, the belt can be assumed to be in an arched position, causing the steel wire to be hooked. As mentioned above, this shortcoming has a low cost, no counterweight lift, because it has a small amount of maintenance to control the level of management. SUMMARY OF THE INVENTION The main object of the present invention is to provide the above-mentioned disadvantages of the prior art. For the purpose of the above-mentioned object, the traction member of the present invention has a plurality of tensile forces 201111265, which are sealed in a casing, wherein the casing has a substantially flat non-working surface and a working surface. The working surface is for contacting a sliding wheel of an elevator driving assembly, which is a concave or convex surface, and the plurality of pulling ropes are located on a plane parallel to the non-working surface. Here, the tension rope refers to a built-in high tension strengthening element in the traction member. According to another embodiment of the invention, the tension cord can have a circular cross section (wire) or any non-circular cross section. According to a preferred embodiment, the tension cord is made of metal wire. Preferably, the tension cord is made of steel wire. In a preferred embodiment, the tension cord is composed of a steel wire having a diameter of 0.5 to 3 mm and more preferably, the spacing 〇 75 to 5 mm is 1 to 3 mm. Another object of the present invention is to provide a traction member having a ratio of the width L of the traction member to the arc height h of the concave working surface in the range of 2 to 1 Torr, and preferably in the range of 2 to 50. In a preferred embodiment, the ratio is approximately five. In other embodiments, the work surface can have projections for engaging the runner grooves. For example, the traction member in accordance with the present invention can be in a toothed configuration. The housing may be fabricated from a suitable plastic material to enclose the built-in tension cable. The purpose of this month is to provide a counterweightless lift that includes a body, a drive system, and a shackle member of the body. Since only the working face, that is, the contact surface with the sheave or the pulley, the good guiding member is suitable for use in a system without counterweight 'like self-supporting 5 S. 201111265 household lift. In fact, to support a body and a counterweight at the same time requires two working faces' or twisting the traction members, which causes rapid wear and is therefore impractical. Since the working surface is concave, the traction member has a smaller cross-section in the central portion, which reduces the need for plastic materials for encapsulation, and also reduces weight and cost. In terms of the process, ’ ‘ arranging the tension cord on a plane parallel to the flat non-working surface 疋 has considerable advantages ’ because the tension rope needs to be placed on a plane and cannot be on different planes. A further important advantage is that because even if the traction member is combined with the sheave in use, the pull cord is held in a plane that is subjected to substantial pure traction stress. In addition, the traction member has an automatic centering capability due to the concave working surface. The traction member of the present invention also has the advantage that it has better adhesion to the sheave than a rope or a conventional flat belt. [Embodiment] An embodiment of the present invention is illustrated with reference to Figs. The figure shows a belt-type 201 elevator good-leading member having a flat non-working surface and a concave or convex working surface on the opposite side. When the working surface is in contact with the bone wheel or pulley during operation, in combination with the belt working surface, the sliding production has a better contact surface with the corresponding convex or concave surface. The belt 201 has a concave working surface 202 on one side opposite to the flat non-working surface 203. The belt 201 is internally strengthened by the highly resistant wires 204 to 204n disposed on the plane g-g parallel to the aforementioned non-working surface 203. Preferably, the ratio of the width L of the belt 201 to the arc height h of the concave working surface 2〇2 (see 6 201111265 Fig. 2) is between 2 and 50. Preferably, the outer surface of Fig. 2 has an outer arc of -2 arc. The wires 204 to 204n are highly resistant to the composite material; preferably, the steel wire having a diameter of 0.5 to 2 mm and the distance between the two wires is preferably [better. In a preferred embodiment, the width L is between 5 and 200 mm, and more preferably, it is in the range of 50 to 150 mm, particularly when used in a counterweightless elevator. There are many options for improving the friction between the belt and the pulley. Figure 4 shows a belt 2〇1 having one of the teeth 205, 207 and a pulley 2〇6 having a tooth 2〇7 for engagement with the tooth 205 of the belt 2〇1 working surface 202. The process of the belt 201 includes the steps of: arranging the reinforcing wires 2〇4~2〇4n on the plane g-g, spaced apart from each other by a distance f, and molding the belt 201 by ejecting the melted plastic material. This process is simpler and less expensive because the reinforcing wire is located on a plane 'i.e., parallel to the plane g-g of the flat non-working surface 2〇3, rather than a curved configuration. Figure 5 illustrates an embodiment of a counterweightless lift that operates through the multiple indexing member of the present invention. The elevator has a cabin 1 which is placed on the second frame / P '3 and has a suspended branch belt 4, 5 which is sheathed over a plurality of sets of coplanar rollers. The first belt 4 is sleeved over the four pulley blocks 6 to 9 and the second belt 5 is sheathed over the other four pulley blocks 6' to 9'. The second belt 4, 5 is an example of the aforementioned belt 2〇1. Two of the several pulley blocks are fixed in the cabin, while the other two are fixed in the guide. The pulley blocks 8, 8' and 9, 9' are fixed to the bottom end and the top end of the frame portions 2, 3, respectively. In the example of Figure ,, the number of pulleys in the parent group is two. The pulley A of each pulley block is 3 and b. For example, the pulley block 6 is constituted by pulleys 6a, 6b. Each slide 201111265 wheel set pulley axis parallel to each other, reaching the pulley coplanar. A motor 10 drives the pulleys 8a, 8, a through the connecting shaft 17. The pulley 8a drives the belt 4' and the pulley 8'a drives the belt 5 on the other side. According to an embodiment of the invention, the two support belts 4, 5 are symmetrically arranged in the side wall 1U2 or in the back wall 13 of the cabin 1. The lift of Fig. 5 is an example of a self-supporting lift. 'Because the cabin 1 and the motor 10 are not required to be heavy-duty by the frame part 2, the 3 branch', the lift is suitable for installation in small and residential buildings, and does not need to be carried out. Invasive civil engineering. Figure 6 shows the belt 201 used in a single belt lift with a cabin 2〇8. The belt is located behind the rear wall of the cabin 208 and is placed over the fixed and moving pulley set. The above-described embodiments are merely examples for the convenience of the description, and the scope of the claims is intended to be limited to the scope of the claims.
