Abstract

A saddle-type vehicle (1) includes: a hydraulic unit (71, 83) configured to receive an operating force and adjust a brake fluid pressure; a heat exchanger (65, 82) configured to dissipate heat of cooling water or engine oil to the outside; and a vehicle body frame (10) configured to support the hydraulic unit and the heat exchanger. The hydraulic unit is located above the heat exchanger, and at least a part of the hydraulic unit overlaps with the heat exchanger in a top view.

Description

TECHNICAL FIELD The present invention relates to a saddle-type vehicle. BACKGROUND ART A saddle-type vehicle equipped with an anti-lock braking system (ABS) device that prevents a front wheel from locking during sudden braking is known (see, for example, Patent Literature 1). In the saddle-type vehicle described in Patent Literature 1, a pair of main frames extend rearward from a head pipe while spreading outwardly to the right and left, and the pair of main frames are covered from outer sides in a vehicle width direction by a front cowl. The ABS device is supported on the main frame on the right side via a stay, and is installed in a space between the main frame on the right side and the front cowl. CITATION LIST PATENT LITERATURE Patent Literature 1: JP4680162B In the saddle-type vehicle described in Patent Literature 1, the ABS device is positioned on the outside of the main frame in the vehicle width direction, and an external impact to the ABS device when the vehicle rolls over is mitigated by a protective frame. However, when the protective frame is provided on the outside of the main frame, there is a problem in that the space between the main frame and the front cowl becomes larger, resulting in an increase in size of a vehicle body. Similar problems can also occur in hydraulic units other than the ABS device. SUMMARY The present invention is made in consideration of the above-described point, and has an object to provide a saddle-type vehicle in which a hydraulic unit can be installed compactly at a front portion of a vehicle, thereby preventing the vehicle from becoming large. A saddle-type vehicle according to an aspect of the present invention includes: a hydraulic unit configured to receive an operating force and adjust a brake fluid pressure; a heat exchanger configured to dissipate heat of cooling water or engine oil to the outside; and a vehicle body frame configured to support the hydraulic unit and the heat exchanger, where the hydraulic unit is located above the heat exchanger, and at least a part of the hydraulic unit overlaps with the heat exchanger in a top view, thereby solving the above-described problem. According to the saddle-type vehicle according to the aspect of the present invention, the hydraulic unit is overlapped on the heat exchanger, so that the hydraulic unit is shifted inward in a vehicle width direction, thereby suppressing an increase in vehicle width dimension. In addition, by positioning the hydraulic unit above the heat exchanger, hot air passing through the heat exchanger is less likely to hit the hydraulic unit, minimizing the effect of heat on the hydraulic unit. BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a left side view of a saddle-type vehicle according to an example.FIG. 2 is a left side view of a periphery of an engine according to the example.FIG. 3 is a front view of the periphery of the engine according to the example.FIG. 4 is a top view of the periphery of the engine according to the example.FIG. 5 is a front view of a periphery of an engine according to a modification example. DESCRIPTION OF EMBODIMENTS In a saddle-type vehicle according to an aspect of the present invention, a hydraulic unit and a heat exchanger are supported by a vehicle body frame. In the hydraulic unit, a brake fluid pressure is adjusted in response to an operating force, and in the heat exchanger, heat of cooling water or engine oil is dissipated to the outside. The hydraulic unit is located above the heat exchanger, and at least a part of the hydraulic unit overlaps with the heat exchanger in a top view. The hydraulic unit is overlapped on the heat exchanger, so that the hydraulic unit is shifted inward in a vehicle width direction, thereby suppressing an increase in vehicle width dimension. In addition, by positioning the hydraulic unit above the heat exchanger, hot air passing through the heat exchanger is less likely to hit the hydraulic unit, minimizing the effect of heat on the hydraulic unit.
