Abstract

Claims (30)

1 . A brake hydraulic pressure control system ( 70 ) for a straddle-type vehicle ( 100 ), the control system ( 70 ) comprising:

a metallic substrate ( 80 ) in which a flow channel for brake fluid is formed;

a control board ( 76 ) of a hydraulic pressure control mechanism for the brake fluid provided in the flow channel; and

a housing ( 85 ) which houses therein the control board ( 76 ) and is connected to the substrate ( 80 ); and

a plate spring ( 90 ) disposed between the control board ( 76 ) and a component that is disposed in a space surrounded by the substrate ( 80 ) and the housing ( 85 ) and that is electrically connected to the substrate ( 80 ),

wherein a free length of the plate spring ( 90 ) is longer than a distance between the control board ( 76 ) and the component,

wherein the plate spring ( 90 ) has a first end part ( 93 ) connected to the control board ( 76 ) and a second end part ( 94 ) connected to the component,

wherein the free length of the plate spring ( 90 ) is longer than the distance between the control board ( 76 ) and the component due to compression of the free length of the plate spring ( 90 ) between the control board ( 76 ) and the component,

wherein the plate spring ( 90 ) includes, at at least one position of a portion between the first end part ( 93 ) and the second end part ( 94 ), a bend part ( 95 ) which bends in a thickness direction of the plate spring ( 90 ),

wherein the plate spring ( 90 ) includes a first plate spring ( 91 ) and a second plate spring ( 92 ), and

wherein the bend part ( 95 ) of the first plate spring ( 91 ) and the bend part ( 95 ) of the second plate spring ( 92 ) bend in opposite directions from each other.

2 . The brake hydraulic pressure control system ( 70 ) according to claim 1 , wherein

the hydraulic pressure control mechanism includes:

a pump device ( 31 ) in the flow channel; and

a motor ( 40 ) which is a driving source for the pump device ( 31 ),

the motor ( 40 ) is disposed in the space surrounded by the substrate ( 80 ) and the housing ( 85 ),

the motor ( 40 ) includes:

a rotor ( 44 );

a stator ( 41 ); and

a motor housing ( 50 ) which houses therein the rotor ( 44 ) and the stator ( 41 ), and the motor housing ( 50 ) is the component.

3 . The brake hydraulic pressure control system ( 70 ) according to claim 2 , wherein the brake hydraulic pressure control system is mounted to the straddle-type vehicle ( 100 ) in such a posture that a width direction of the plate spring ( 90 ) does not extend horizontally.

4 . The brake hydraulic pressure control system ( 70 ) according to claim 1 , wherein the plate spring ( 90 ) includes, in the second end part ( 94 ), a planar part ( 97 ) which is connected to the component.

5 . A straddle-type vehicle ( 100 ) comprising the brake hydraulic pressure control system ( 70 ) according to claim 1 .

6 . The brake hydraulic pressure control system ( 70 ) according to claim 2 , wherein the plate spring ( 90 ) includes, at at least one position of a portion between the first end part ( 93 ) and the second end part ( 94 ), a bend part ( 95 ) which bends in a thickness direction of the plate spring ( 90 ).

7 . The brake hydraulic pressure control system ( 70 ) according to claim 6 , wherein

the plate spring ( 90 ) includes a first plate spring ( 91 ) and a second plate spring ( 92 ), and

the bend part ( 95 ) of the first plate spring ( 91 ) and the bend part ( 95 ) of the second plate spring ( 92 ) bend in opposite directions from each other.

8 . The brake hydraulic pressure control system ( 70 ) according to claim 7 , wherein the brake hydraulic pressure control system is mounted to the straddle-type vehicle ( 100 ) in such a posture that a width direction of the plate spring ( 90 ) does not extend horizontally.

9 . The brake hydraulic pressure control system ( 70 ) according to claim 8 , wherein the plate spring ( 90 ) includes, in the second end part ( 94 ), a planar part ( 97 ) which is connected to the component.

10 . The brake hydraulic pressure control system ( 70 ) according to claim 1 , wherein the component is a motor housing ( 50 ).
