- FIG. 1 shows a portion in front of a driver seat viewed from the cabin side of a cab over type motor vehicle using the joint construction for a brake pipe in accordance with the present invention. In front of the driver seat, an accelerator pedal1 and a
brake pedal 2 are disposed. This cab over type vehicle is provided with abrake booster 3 and amaster cylinder 4 on the cabin side. Also, this vehicle is provided with a foot-type foot parking brake, and a control unit of the foot parking brake is disposed around the driver's foot. - FIGS. 2 and 3 show a
control unit 5 a of thefoot parking brake 5. The foot parking brake is attached to anattachment bracket 7 fixed to adash panel 6 for separating the inside of the cabin (IN side) from the outside of the cabin (OUT side). Anarm 8 of thecontrol unit 5 a is pivotally supported so as to be turnable around the axis ofrotation 9. On the upper end side of one end of thearm 8 is provided aparking cable 10, and on the other side thereof is provided apedal 11. On the front side of theattachment bracket 7 and thecontrol unit 5 a of foot parking brake with respect to a vehicle body, aconnection joint 12 is installed. - FIGS. 4 and 5 are enlarged views of the
connection joint 12. Theconnection joint 12, having an L-shaped cross section, is installed to thedash panel 6 erected vertically to separate the cabin from the outside of the cabin. To theconnection joint 12, ofbrake pipes 13 shown in FIG. 6, a pair of cabin-side brake pipes 14 disposed on the IN side andoutside brake pipes 15 disposed on the OUT side are connected. - Of these brake pipes, the cabin-
side brake pipes 14 are disposed between themaster cylinder 4 and theconnection joint 12, and one end thereof is connected to theconnection joint 12. Theconnection joint 12 is disposed in such a manner that a cabin-side connector 17 of theconnection joint 12 faces to the direction in which thedash panel 6 extends in the state in which theconnection joint 12 is installed to thedash panel 6. The direction of the cabin-side connector 17 may be any direction in which thedash panel 6 extends, upward, downward, leftward, or rightward. In this embodiment, the cabin-side connector 17 is disposed so as to face to the upward direction. - Also, the
outside brake pipes 15 are disposed between theconnection joint 12 and aproportioning valve 65, and one end thereof is connected to theconnection joint 12. An outside connector 18 of theconnection joint 12 is disposed so as to be substantially perpendicular to the direction in which thedash panel 6 extends, that is, so as to face to the vehicle front side. - The
connection joint 12 is fitted with a pair ofbolts 21 which penetrate screw holes (not shown) formed in thedash panel 6, and is fixed to thedash panel 6 by usingnuts 22. As shown in FIG. 4,attachment portions 23 for thebolt 21 are projected to the outside, and are disposed on a diagonal line of amounting flange 20 having a substantially rectangular shape. Theattachment portions 23 for thebolt 21 are located on the diagonal line in this manner, or may be located at point symmetrical positions with respect to the center of themounting flange 20. Also, theconnection joint 12 is formed with themounting flange 20 projecting downward along the surface of thedash panel 6, and asealing packing 26 is disposed on the face of themounting flange 20. Theconnection joint 12 is mounted to thedash panel 6 so as to penetrate a throughhole 24 formed in thedash panel 6. - As shown in FIG. 5, the
connection joint 12 forms an L-shaped passage 25 along the L-shaped cross section thereof. The cabin-side brake pipes 14 are laid out in such a manner as to be substantially in parallel with thedash panel 6 by locating the connection end of the cabin-side brake pipe 14 on the side of theconnection joint 12 close to the surface of thedash panel 6 to which theconnection joint 12 is attached. Also, theoutside brake pipes 15 are disposed in such a manner that the connection end of theoutside brake pipe 15 on the side of theconnection joint 12 is once extended to the vehicle front side so as to be substantially perpendicular to thedash panel 6, being curved downward, and is extended along the OUT side of the surface of thedash panel 6. - The
connection joint 12 is disposed in front of thefoot parking brake 5 and at a position where thefoot parking brake 5 and the cabin-side brake pipes 14 lap on each other on the cabin side of thedash panel 6. - Since this embodiment is configured as described above, the cabin-
side brake pipes 14 can be disposed along the surface of thedash panel 6 right from the end of theconnection joint 12. Therefore, unlike the conventional construction, it is unnecessary for the cabin-side brake pipes 14 to be projected once to the cabin side before being disposed along the surface of thedash panel 6, so that a space can be provided accordingly. Thereupon, although it has conventionally been difficult to arrange thecontrol unit 5 a of the foot parking brake at the rearward of the connection joint 12, such arrangement can be accomplished by applying the present invention. In this embodiment, the connection joint 12 is formed into an L shape in cross section, and only the cabin-side connector 17 is disposed along the surface of thedash panel 6. However, the connection joint 12 may be formed into a U shape or a crank shape in cross section so that not only the cabin-side connector 17 but also the outside connector 18 on the outside of the cabin are disposed along the surface of thedash panel 6. - Also, by disposing the
attachment portions 23 for thebolt 21 so as to be located on the diagonal line of the mountingflange 20 having a substantially rectangular shape, the sealing property of the packing 26 can be increased despite the fact that the pairedbolts 21 andnuts 22 provide a small number of attachment locations. - The above is a description of an embodiment of the present invention. Needless to say, the present invention is not limited to this embodiment, and various changes and modifications can be made based on the technical concept of the present invention.
- For example, although the connection joint12 is located at a position a little closer to the center of the
dash panel 6 as shown in FIG. 1 in the above-described embodiment, the connection joint 12 may be located at any position on thedash panel 6. - Also, in the above-described embodiment, as shown in FIG. 2, the lower-side portion of the
dash panel 6 corresponding to the attachment portion of the connection joint 12 is projected to the outside of the cabin, and the connection joint 12 is installed in the projected portion of thedash panel 6. However, thedash panel 6 may appropriately be formed into a shape such as to correspond to a vehicle-side structural member disposed near the connection joint 12. Even if thedash panel 6 has a flat plate shape, the present invention can be applied. - Also, regarding the vehicle-side structural member, the connection joint may be disposed at a position where not the
control unit 5 a of the foot parking brake but a structural member such as a clutch pedal attachment bracket is disposed. - As described above, according to the joint construction for a brake pipe in accordance with the present invention, in the joint construction for a brake pipe, comprising a pipe joint which penetrates a vehicle body panel and is installed to the vehicle body panel; and brake pipes connected to the cabin-side connector of the pipe joint and the outside connector thereof, of the cabin-side connector and the outside connector of the pipe joint, at least either one of the connectors is provided so as to face to the direction parallel with the vehicle body panel, and the brake pipe connected to the connector is disposed along the surface of the vehicle body panel. Therefore, a space is not needed around the connector of the joint, and the brake pipe can be laid out in a tight space.
- Also, in the present invention, the vehicle body panel is the dash panel, the cabin-side connector of the pipe joint is provided so as to face to the direction parallel with the dash panel and the dash panel is provided with the control unit of the foot parking brake, and the control unit is disposed just at the rear of the pipe joint. Therefore, a large mounting space for the joint is not needed around the dash panel in the portion where the joint is disposed.
- Further, in the present invention, the pipe joint is formed into an L shape in cross section so that an outside connector is disposed so as to face to the direction in which the brake pipe and the dash panel intersect at right angles.
- Still further, in the present invention, the pipe joint is fixed to the vehicle body panel via a sealing member using a pair of bolts, and the paired bolts are arranged on a diagonal line. Therefore, the sealing property of the sealing member is improved.
