Description

  The present invention particularly relates to a parking cable routing structure immediately upstream of a parking drum.

  For example, as disclosed in Patent Document 1, the parking cable is slidably penetrated into a cylindrical casing, and a plurality of locations in the middle of the casing are fixed to the body frame using clips or clamps as appropriate. As a result, it is routed while curving the lower part of the vehicle body and guided to the brake drum.

In this case, from the standpoint of protecting the parking cable, avoiding interference of the parking cable with the edges of the parts on the vehicle body side, especially on the upstream side of the parking drum that moves violently up and down by the movable mechanism around the suspension. It is indispensable. Therefore, in general, the parking cable is routed on the parking drum while curving in a direction to bypass the vehicle body parts that may interfere.

  However, since there is a limit to the bending of the parking cable, it may be difficult to route the parking cable while detouring the vehicle body parts due to the bending in a recent vehicle body with a complicated suspension structure and the like.

  To cope with this, for example, it is conceivable to avoid interference with vehicle body side parts by forming a base by welding a sheet metal or the like formed in a hat shape to the vehicle body and fixing a parking cable on the base. However, floating the parking cable from the vehicle body via the pedestal in this way may increase the number of parts and lead to a complicated structure.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a parking cable routing structure that can accurately prevent interference with peripheral components due to vertical movement of the undercarriage with a simple configuration. And

  The present invention is a bracket that pivotally supports a fixed end portion of a link or an arm that constitutes a rear suspension between a pair of support plates that project in the front-rear direction and project downward from a vehicle body while allowing the fixed end of the arm to swing in the vertical direction. A parking cable routing structure for a vehicle, comprising: a pair of support plates, wherein at least a part of the height of the support plates is asymmetrically formed; The parking cable holding mechanism is provided at an edge, and the parking cable is extended from the front of the vehicle body by the holding mechanism so that the lower edge of the other supporting plate is positioned above the one supporting plate.

It is pivotally supported. As a result, the trailing link 31 has its free end directed to the outside of the rear part of the vehicle body 1 and is swingable in the vertical direction. Further, the free end portion 31 b of the trailing link 31 is supported in front of the lateral links 21 and 22 and supported by the lower portion of the hub carrier 17 via an elastic bush 33.

  A bracket 35 is fixed to the lower surface of the vertical frame portion 5, and a fixed end portion 36 a of a toe control link 36 is pivotally supported on the bracket 35. Thereby, the free end side of the toe control link 36 is directed to the outside of the vehicle body 1 and can swing up and down. Further, the free end portion 36 b of the toe control link 36 is pivotally supported by an arm portion 17 a extending forward from the hub carrier 17 via an elastic bush 38.

  As described above, in the present embodiment, a double wishbone rear suspension is formed at the rear portion of the vehicle body 1. In this suspension structure, as shown in FIG. 4, the bracket 35 that supports the toe control link 36 on the vehicle body side has a pair of support plates 50 and 51 that project in the lower side of the vehicle body 1 so as to face in the front-rear direction. The bracket 35 pivotally supports the fixed end portion of the toe control link 36 between the support plates 50 and 51.

  As shown in FIGS. 3 and 4, the support plates 50 and 51 are formed so that the height of a part of them is asymmetric. Hereafter, of the pair of front and rear support plates 50 and 51 shown in FIG. 4, the support plate 50 located in front of the vehicle body 1 is referred to as a first support plate, and the support plate 51 located in the rear is designated as a second support plate. This is called a plate.

  More specifically, the first and second support plates 50 and 51 have their edges 50a and 51a having heights in the region extending inward of the vehicle body 1 from the support portion of the toe control link 36. It is formed asymmetrically. That is, as shown in FIGS. 3 and 4, in the region extending inward of the vehicle body 1, the first support plate 50 is formed to be longer in the vertical direction than the second support plate 51. Thus, the edge portion 50 a of the first support plate 50 is set to be positioned relatively lower than the edge portion 51 a of the second support plate 51.

  A holding mechanism 55 that holds the parking cable 58 is provided on the edge of the first support plate 50 that is positioned relatively below the edge 51 a of the second support plate 51. The holding mechanism 55 includes a cable bracket 56 that is fixed to the first support plate 50 by bolt fastening or the like. The cable bracket 56 is composed of a sheet metal member having a substantially L-shaped cross section on the upper side, and has a function of a cable band on the lower side (see FIG. 3). The holding mechanism 55 supports the parking cable 58 on the vehicle body 1 by winding the cable bracket 56 in the middle of the parking cable 58 extending from the front of the vehicle body 1.

  At this time, as shown in FIG. 1, the parking cable 58 is held relative to the first support plate 50 by holding the parking cable 58 in a state where the cable bracket 56 is oriented outwardly from the rear portion of the vehicle body 1. It crosses below the edge 51a of the second support plate 51 located above and reaches the hub carrier 17 side (that is, a parking drum (not shown)).

  According to such an embodiment, the height of a part of the first and second support plates 50 and 51 is formed asymmetrically and is held at the edge of the first support plate 50 positioned relatively below. By providing the mechanism 55, the middle of the parking cable 58 can be held away from the bottom surface of the vehicle body 1 with a simple configuration without separately providing a pedestal or the like. At that time, the cable bracket 56 of the holding mechanism 55 causes the parking cable 58 to be positioned below the edge portion 51a of the second support plate 51 that is positioned above ΔH (see FIG. 3) relative to the first support plate 50. To reach the hub carrier 17 side, the contact between the parking cable 58 and the second support plate 51 can be accurately avoided.

  Further, by using the bracket 35 that supports the toe control link 36 for the routing of the parking cable 58, the holding point of the parking cable 58 can be set in the vicinity of the fulcrum of the toe control link 36. Therefore, the swing of the parking cable 58 accompanying the vertical movement of the suspension mechanism and the swing of the toe control link 36 and the like can be substantially matched, and interference between the suspension mechanism arms and links and the parking cable 58 can be accurately achieved. Can be avoided.

  Further, by forming the height of the first and second support plates 50 and 51 asymmetrically, it is possible to secure a working space when the cable bracket 56 is bolted to the first support plate 50, Workability at the time of routing of the parking cable 58 can be improved.

  Here, as shown in FIG. 5, the bracket 35 may be configured by reversing the front and rear positions of the first support plate 50 and the second support plate 51. With this configuration, the swinging fulcrum of the parking cable 58 accompanying the vertical movement of the suspension mechanism can be set on the downstream side (rear side of the vehicle body 1) from the second support plate 51, so parking can be performed more reliably. Interference between the cable 58 and the second support plate 51 can be avoided.

  In the above-described embodiment, an example of holding the middle of the parking cable 58 using the bracket 35 that supports the toe control link 36 has been described, but the present invention is not limited to this, and the parking cable 58 is not limited thereto. Of course, other arms that swing in the up-down direction or brackets such as links may be used for holding.
