Description

  The present invention relates to a front structure of a saddle-ride type vehicle such as a motorcycle.

  Conventionally, an opening is provided in the front cowl that covers the front of the body of a saddle-ride type vehicle such as a motorcycle, and air travel is introduced through this opening into an oil cooler (heat exchanger) located near the headlight. It is known (see Patent Document 1 below). The oil cooler is connected to an oil tank provided inside the fuel tank via a pipe. In this prior art, the headlight and the heat exchanger are arranged in the left-right direction.

JP-A-9-95273

  However, if a structure in which headlights and heat exchangers are arranged in the vertical direction is adopted in this conventional technique, the front cowl becomes large in the vertical direction. For this reason, it has been difficult to achieve both design (appearance merchandise) and function (particularly, wind guide to the heat exchanger).

  The present invention is a front structure of a saddle-ride type vehicle in which a heat exchanger is disposed in the vicinity of a headlight. The front structure of the saddle-ride type vehicle ensures high designability and high wind conductivity to the heat exchanger. The purpose is to provide a structure.

The invention according to claim 1 is a front structure of a saddle-ride type vehicle including a stay for attaching a headlight to a vehicle body, and a heat exchanger attached to the stay and disposed in the vicinity of the headlight. The heat exchanger is disposed below the headlight, and the saddle-ride type vehicle includes a lower guide wall member continuously extending forward and downward from a front lower end portion of the heat exchanger, and a lower surface of the headlight. And an upper guide wall member connecting the front upper end of the heat exchanger, and an air guide path is formed between the lower surface of the headlight and the lower guide wall member, and the wind guide By the road, the traveling wind is directed to the heat exchanger, and the rear portion of the upper guide wall member and the front upper end portion of the heat exchanger are disposed at a position higher than the lower surface of the headlight in the center in the left-right direction. It is characterized by that.

  According to a second aspect of the present invention, the heat exchanger is attached to the stay in a tilted state, and the lower guide wall member is tilted backward so as to form an obtuse angle with the heat exchanger. In this state, it is attached to the stay.

  According to a third aspect of the present invention, the lower surface of the headlight has an upwardly convex shape in a front view, and is substantially isosceles triangular by the lower surface of the headlight and the upper surface of the lower guide wall member. An introduction port for the air guide path is formed.

  The invention according to claim 5 further includes a side guide wall member that connects both ends of the upper guide wall member and both ends of the lower guide wall member.

  The invention according to claim 6 is characterized in that the heat exchanger is an oil cooler, and a front cowl and a mirror are attached to an upper portion of the stay.

  The invention described in claim 7 is characterized in that a regulator is attached to one side portion of the stay, and a relay is attached to the other side portion of the stay.

  According to the first aspect of the present invention, the heat exchanger and the lower guide wall member can be arranged in a limited space below the headlight. Therefore, while ensuring the design, the heat exchanger and the lower guide wall member can be arranged in a compact manner, and the traveling wind can be efficiently guided to the heat exchanger.

  According to the invention described in claim 2, since the obtuse angle is formed between the lower guide wall member and the heat exchanger, the lower guide wall member is inclined toward the front lower side. Therefore, the traveling wind can be introduced not only from the front side but also from the front wheel side, and the cooling effect of the heat exchanger can be improved.

  According to the third aspect of the present invention, it is possible to efficiently ensure a large inlet for the air guide path in a limited space below the headlight. Therefore, the cooling effect of the heat exchanger can be improved.

According to the first aspect of the present invention, the traveling wind that has passed under the headlight can be guided to the heat exchanger with little loss and applied to the heat exchanger. Therefore, the cooling effect of the heat exchanger can be improved.

  According to the fifth aspect of the present invention, the traveling wind introduced into the air guide path can be guided to the heat exchanger with a small loss in the left-right direction (vehicle width direction) and applied to the heat exchanger. . Therefore, the cooling effect of the heat exchanger can be improved.
