Abstract
The invention relates to a control pull cable of an automotive vehicle, and discloses a friction-reducing device for the control pull cable of the automotive vehicle. The friction-reducing device comprises a pull cable core (1) and a pull cable protecting tube (2), and is characterized by also comprising a turning bracket (3), a turning guide rail (4) and a flexible belt, wherein the turning guide rail (4) and the turning bracket (3) are fixedly connected into a whole; the turning bracket (3) is connected with the pull cable protecting tube (2); the flexible belt is positioned on the turning guide rail (4) and moves by attaching to the turning guide rail; the pull cable core (1) is connected with the flexible belt. Due to the adoption of the friction-reducing device, the problem that the friction resistance and wear between the core at the bending part of the pull cable and the protecting tube are large is solved, and the service life of the pull cable is greatly prolonged.
Description
Technical field
The present invention relates to operating automobile drag-line, especially operating automobile drag-line anti-attrition device.
Background technique
Known manipulating pulling cable mainly contains core and pillar forms, pillar has certain flexible, clutch cable is crooked at use state mostly, some is curved also more severe, even also a more than place is crooked, this serves problem with regard to band, as everybody knows, some drag-line load is larger, such as clutch cable, at crooked position, between core and pillar, can produce larger surface friction drag, larger surface friction drag is easy to make core and pillar to produce wearing and tearing, and core and the pillar of wearing and tearing can increase surface friction drag, Here it is, and tortuosity is large, the clutch cable short basic reason in working life that load is large.
Content of the present invention
In order to overcome above-mentioned defect, the present invention is provided with anti-attrition device at the crooked position of drag-line, and this anti-attrition device has alleviated the large and large problem of wearing and tearing of the surface friction drag of crooked position of drag-line.
The technical solution adopted for the present invention to solve the technical problems is: operating automobile drag-line anti-attrition device, comprise drag-line core and drag-line pillar, also comprise curved support, crossed curved guide rail, flexible-belt, the curved guide rail of described mistake and excessively curved support are solidified as a whole, crossing curved support is connected with drag-line pillar, flexible-belt was pressed on curved guide rail and was pasting and crossing curved guide rail movement, and drag-line core is connected with flexible-belt.
Described flexible-belt comprises flexible sheet metal piece, and drag-line core is connected with flexible sheet metal piece.
Described flexible-belt comprises chain, and in chain inner side, roller rolls and contacts with excessively curved guide rail.
The carrier bar of described chain is connected with drag-line core.
The outside of described chain, roller rolls and contacts with drag-line core.
The invention has the beneficial effects as follows, owing to adopting curved guide rail and flexible-belt at drag-line crooked position, alleviated surface friction drag and the wearing and tearing of drag-line at crooked position, the working life of having improved drag-line.

In figure: 1 drag-line core, 2 drag-line pillars, 3 cross curved support, and 4 cross curved guide rail, 5 flexible sheet metal pieces, 6 chains, 7 rollers, 8 bearing pins, 9 inner plates, 10 outer plates.
Specific embodiment
As shown in Fig. 1 Fig. 2, drag-line pillar 2 with cross curved support 3 and be connected, cross curved support 3 and be solidified as a whole with the curved guide rail 4 of mistake, ganoid flexible sheet metal piece 5 is pressed on the curved guide rail 4 of ganoid mistake, drag-line core 1 is connected with the end of flexible sheet metal piece 5.When drag-line core 1 is during in the interior motion of drag-line pillar 2, flexible sheet metal piece 5 is being crossed slip on curved guide rail 4, because flexible sheet metal piece 5 is to cross force of sliding friction on the curved guide rail 4 surface of contact frictional force that the suffered pressure of the slip unit area in drag-line pillar 2 is little, smooth compared with drag-line core 1 little, thereby drag-line crooked position surface friction drag and wearing and tearing have been alleviated.
As shown in Fig. 3 Fig. 4, drag-line pillar 2 with cross curved support 3 and be connected, cross curved support 3 and be solidified as a whole with crossing curved guide rail 4, the roller 7 on chain 6 with curved guide rail 4 rollings contact, drag-line core 1 is connected with the carrier bar of chain 6.When drag-line core 1 is during in the interior motion of drag-line pillar 2, roller 7 rolls crossing on curved guide rail 4, and the force of sliding friction in drag-line pillar 2 is little compared with drag-line core 1 for its rolling friction power, thereby has alleviated drag-line crooked position surface friction drag and wearing and tearing.
As shown in Fig. 5 Fig. 6, drag-line pillar 2 with cross curved support 3 and be connected, cross curved support 3 and be solidified as a whole with crossing curved guide rail 4, in chain 6 inner sides, roller 7 contacts with crossing curved guide rail 4 rollings, in chain 6 outsides, roller 7 contacts with 1 rolling of drag-line core.When drag-line core 1 is during in the interior motion of drag-line pillar 2, roller 7 not only rolls but also rolls and contact with drag-line core 1 on the curved guide rail 4 of mistake, the force of sliding friction in drag-line pillar 2 is little compared with drag-line core 1 for its rolling friction power, thereby has alleviated drag-line crooked position surface friction drag and wearing and tearing.
