Cable drive system for vehicles

The present invention is related to an actuation system, and more particularly to a cable-type actuation system for a vehicle.

Cables are commonly used in brake systems or shifting systems. Cables for general vehicles are made up of a plurality of wires that are cut to the required length as required. However, the wire is sharpened and easily split at the end after cutting, and the sharp wire is easily separated and inserted into the outer catheter when the outer catheter is worn, which makes installation difficult and damages the external catheter, and is disclosed by TWM365315 and TW225222. That is the case.

The conventional structure also has a metal tail sleeve sleeved on the exposed and sharp end of the cable after the cable system is clamped to the clamping mechanism of the brake device or the transmission, and the metal tail sleeve is strongly pressed to clamp the cable. The end of the line to avoid damage, but the need to purchase and install the metal tail sleeve, and will force the wire to spread out and damage the cable, as disclosed by TWM362811.

Therefore, it is necessary to provide a novel and progressive vehicle wire drive system to solve the above problems.

The main object of the present invention is to provide a cable-type actuation system for a vehicle, wherein one end of the cable body is set as a fusion end and can be smoothly passed through the external conduit and avoids the insertion of the external conduit, and the end can be ensured. The strength of the fusion.

In order to achieve the above object, the present invention provides a cable-type actuation system for a vehicle, comprising a cable body and a tail sleeve, wherein the cable body is formed by a plurality of wire unit assemblies, and the ends of the plurality of wire units are integrally formed. In a fusion end, the cable body is disposed opposite to a portion of the fusion end in a vehicle, and the tail sleeve is sleeved on the fusion end.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIGS. 1 to 4, a cable drive system for a vehicle according to a preferred embodiment of the present invention is disclosed. The cable drive system for a vehicle includes a cable body 10, and the cable body 10 is composed of a plurality of wires. The unit 11 is configured to be (for example, spiral or otherwise bonded, the wire may be metal or composite), and the ends of the plurality of wire units 11 are integrally fused to form a fusion end 12, and the cable body 10 is provided close to the One portion of the fusion end 12 is relatively positioned in a vehicle (eg, a bicycle, motorcycle, etc.).

In detail, the vehicle cable actuation system may further include an actuation mechanism 20 and an operating mechanism 30. The cable body 10 is operatively coupled between the actuating mechanism 20 and the operating mechanism 30. The operating mechanism 30 is operable to drive the cable body 10 to actuate the actuating mechanism 20. In this embodiment, the actuating mechanism 20 is disposed on a bicycle brake device (see FIG. 3). The operating mechanism 30 is, for example, a pressing grip provided on the bicycle, and the actuating mechanism 20 can also be a shifting device. (See Figure 5). The cable body 10 is clamped to the clamping mechanism 21 of the actuating mechanism 20, and the melting end 12 is located outside the clamping mechanism 21.

The fusion end 12 can prevent the plurality of wire units 11 from being separated and the external conduit 40 is inserted. The surface of the fusion end 12 is a continuous curved convex surface 121, so that the cable body 10 can be smoothly passed through. External conduit 40. The cable body 10 further includes a wire assembly body 13 that is integrally connected to one end of the wire assembly body 13 in an expanded manner. One side of the melting end 12 extends beyond the wire assembly body 13 by a predetermined distance d (as shown in FIG. 6) in the radial direction of the cable body 10, and the predetermined distance d is preferably between the wire unit 11. The wire diameter is between 0.3 times and 1.5 times, so that the friction between the wire collecting body portion 13 and the outer pipe 40 having the smaller diameter in the rear portion can be reduced.

Preferably, the extension L of the fusion end 12 along the length direction of the cable body 10 is between 1 and 5 times the wire diameter of the wire unit 11. In a section of the fusion end 12 along the length direction of the cable body 10, the wire assembly body 13 and the fusion end 12 intersect to form a diplomatic flange 14 and an inner interface 15 (see FIG. 6 to 8)). The fusion end 12 further includes a distal end surface 122. The size of the inner interface surface 15 to the end surface 122 is preferably between 0.5 and 8 times the diameter of the wire unit 11 according to the size of the different wire unit. (preferably not less than 1 time), the end fusion strength of the plurality of wire units 11 can be ensured.

In addition, please refer to FIG. 9 , a sleeve 50 , such as a metal sleeve, may be additionally disposed on the fusion end 12 , and the inner wall of the sleeve 50 includes a flanged body 12 along the cable body 10 . The card abutting portion 51 interferes in the longitudinal direction, and the card abutting portion 51 is formed by externally pressing the inner wall of the tail sleeve 50 by pressing, thereby eliminating the need to strongly press the tail sleeve 50 and strongly clamping the cable body. 10 can be effectively assembled without damaging the cable body 10, and the plurality of wire units 11 are also kept assembled without being scattered. Alternatively, the tail sleeve 50 can also be assembled to the fusion end 12 through a connecting member, such as a glue body, tape or the like to bond the tail sleeve 50 and the fusion end 12, or the tail sleeve 50 and the melt The knot end 12 is provided with an elastic medium and elastically tightly assembled, or the tail sleeve 50 can be directly assembled with the fusion end 12, and any means for combining the tail sleeve 50 and the fusion end 12 can be used. Do not rule out.

In summary, the end of the cable body of the cable-type actuation system for a vehicle of the present invention is provided as a fusion end, which can be smoothly passed through the external conduit and avoids the insertion of the external conduit, and can ensure the plurality of wire units. End fusion strength.

In addition, a tail sleeve that can be engaged with the fusion end can be additionally sleeved on the fusion end without damaging the cable body.
