The front wheel brake BF1 is a drum brake that exerts a braking force in response to = operational input to a brake cam arm 24. The rear wheel WR is provided with a rear wheel o brake BR; the rcar wheel brake BR is also a drum brake, and exerts a braking force in response to operational input to a brake cam arm 25.
Referring in addition to FIG. 3, a brake pedal 26 is pivotably supported on the pivot frame 14 of the vehicle body frame F, and an equalizer 28 for distributing the operating force of the brake pedal 26 between the front wheel brake BF1 and the rear wheel brake BR is linked to an operating arm 27 provided connectedly and integrally with the brake pedal 26.
Linked to this equalizer 28 are one end part of a coupling brake cable 29 as front operating force transmission means that transmits the operating force distributed to the front wheel brake BF1 side and a front end part of a brake rod 30 as rear operating force transmission means that transmits the operating force distributed to the rear wheel brake BR side.
Linked in parallel to the brake cam arm 24 of the front wheel brake BF1 are the other end part of the front wheel brake cable 23 and the other end part of the coupling brake cable : 29, and linked to the brake cam arm 25 of the rear wheel brake BR is a rear end part of the brake rod 30. Moreover, the brake cam arm 25 of the rear wheel brake BR is disposed so that it is pivotably supported on a support portion 37a of a brake panel 37 of the rear wheel brake
BR so as to extend upward from the support portion 37a, and a rear end part of the brake rod disposed above the swing arm 18 is linked to an upper end part of the brake cam arm 25.
The brake pedal 26 extends forward while a base end part of the brake pedal 26 is pivotably supported, via a support shaft 32, on the pivot frame 14 of the vehicle body frame F : beneath a straight line L joining the center of an axle 31 of the rear wheel WR and the center of the pivot shaft 19, and a pedal portion 26a is provided on a forward end part of the brake pedal 26. Furthermore, the operating arm 27 is connectedly provided integrally with the basc = end part of the brake pedal 26 and extends upward. "
The equalizer 28 is disposed so as to extend vertically above the brake pedal 26, an ~ upper end part of the operating arm 27 is linked to one end part (lower end part) of the i” equalizer 28, one end part of the coupling brake cable 29 is linked to the other end part (upper ow end part) of the equalizer 28, and one end part of the brake rod 30 is linked to an intermediate co part of the equalizer 28. Moreover, a linking point P of the brake rod 30 and the equalizer 28 = is disposed above a lower edge 18a of the swing arm 18, that is, above the straight line L o joining the center of the axle 31 of the rear wheel WR and the center of the pivot shaft 19. «
The coupling brake cable 29 is formed by movably inserting an inner cable 34 through an outer cable 33, a cable support portion 35a positioned in front of the equalizer 28 is provided on a stay 35 supported on the pivot frame 14 and the engine main body 15, and one end part of the inner cable 34 projecting from one end part of the outer cable 33 supported by the cable support portion 35a is linked to the upper end part of the equalizer 28 from the front.
Furthermore, a delay spring 36 urging the equalizer 28 in the same direction as the direction of movement of the operating arm 27 accompanying operation of the brake pedal 26 is connected to a section of the other end part of the equalizer 28 that is further outside than the linking point of the coupling brake cable 29. :
The delay spring 36 is a coil spring, a spring force adjustment member 37 is mounted on a spring support portion 35b provided on the stay 35 so as to be positioned in front of the cable support portion 35a so that the back and forth position in the fore-and-aft direction to ’ which the spring force adjustment member 37 is moved can be adjusted, and a rear end part of - the delay spring 36 whose front end part is connected to the spring force adjustment member 37 is connected to. a section of the upper end part of the equalizer 28 that is further outside than the linking point of the coupling brake cable 29.
Furthermore, provided on the stay 35 is a stopper 35c opposing, from the front, a section of the equalizer 28 to which the coupling brake cable 29 is linked. The upper end part ~ of the equalizer 28 in a non-operated state of the brake pedal 26 is urged by the delay spring 36 and abuts against the stopper 35c.
The operation of the first embodiment is now explained; since the upper end part of = the operating arm 27 is linked to one end part (the lower end part) of the equalizer 28, the . coupling brake cable 29, which transmits the operating force to the front wheel brake BF1, is ~ linked to the other end part (upper end part) of the equalizer 28, and the brake rod 30, which . transmits the operating force to the rear wheel brake BR, is linked to the intermediate part of ? the equalizer 28, when in a non-operated state of the brake pedal 26 as shown in FIG. 4 (a) the brake pedal 26 is depressed, the brake pedal 26 pivots in response to the depressing operation = of the brake pedal 26, as shown in FIG. 4 (b) the equalizer 28 operates in the same direction ° ; as the direction of movement of the operating arm 27 with, as a fulcrum, the part where it abuts against the stopper 35¢ on the other end part side, and a force in the same direction as the direction of movement of the operating arm 27 accompanying pivoting of the brake pedal 26 acts on the brake rod 30 linked to the intermediate part of the equalizer 26. In this process, since the stopper 35¢ opposes, from the front, the section of the equalizer 28 to which the coupling brake cable 29 is linked, no force acts on the coupling brake cable 29 from the equalizer 28.
When the brake pedal 26 is further pivoted by increasing the depressing force of the brake pedal 26, since the reaction force from the brake rod 30 has become large, a force in the opposite direction to the direction of movement of the operating arm 27 acts on the other end part of the equalizer 28 with the linking point P of the intermediate part of the equalizer 28 and the brake rod 30 as the fulcrum, and if this force exceeds the spring force of the delay spring 36, as shown in FIG. 4 (c) the other end part of the equalizer 28 pivots in the opposite direction to the direction of movement of the operating arm 27, and a force in the opposite direction to the direction of movement of the operating arm 27 can be made to act on the coupling brake cable 29 from the equalizer 28.
Furthermore, since the linking point P of the brake rod 30 and the equalizer 28 is : : disposed above the lower edge 18a of the swing arm 18, it is possible to ensure that there is a relatively large distance from the base end part of the brake pedal 26, that is, the base end part ; . of the operating arm 27, up to the linking point P of the brake rod 30 and the equalizer 28, thereby enabling the amount of operation of the operating arm 27 to be increased, and it is ’
possible to easily position the coupling brake cable 29 in front of the equalizer 28 while = avoiding interference with the engine E. .
Moreover, since the base end part of the of the brake pedal 26 is pivotably supported ~ on the pivot frame 14 beneath the straight line L joining the center of the axle 31 of the rear ~ wheel WR and the center of the pivot shaft 19 swingably supporting the front end part of the 7 swing arm 18 on the pivot frame 14 of the vehicle body frame F, and the linking point P of the o brake rod 30 and the equalizer 28 is disposed above the straight line L, it is possible to ensure = that there is a relatively large distance from the base end part of the brake pedal 26, that is, the = base end part of the operating arm 27, up to the linking point P of the brake rod 30 and the = equalizer 28, and the amount of operation of the operating arm 27 can be increased.
Furthermore, since the linking point P is disposed so as to be offset further toward one side of the equalizer 28 than a center C in the longitudinal direction of the equalizer 28, it is possible to ensure the arm ratio up to the linking point of the coupling brake cable 29, and it is thereby possible to ensure the force acting on the coupling brake cable 29.
Moreover, since the delay spring 36, which urges the equalizer 28 in the same direction as the pivoting direction of the brake pedal 26, is connected to the other end part of the equalizer 28, the timing with which the operating force is transmitted to the front wheel brake BF1 side by a depressing operation of the brake pedal 26 can be determined by setting the spring load of the delay spring 36. Furthermore, since the delay spring 36 is connected to a section of the other end part of the equalizer 28 further outside than the linking point of the coupling brake cable 29, it is possible to casily ensure the point at which the delay spring 36 is connected to the equalizer 28.
Furthermore, since a rear end part of the brake rod 30 disposed above the swing arm 18 is pivotably supported on the support portion 37a of the brake panel 37 of the rear wheel brake BR, which is a drum brake, and is linked to the upper end part of the brake cam arm 25 extending upward from the support portion 37a, it becomes possible to carry out the design ‘without concerns about the height above the ground of the brake cam arm 25. ~~ SECOND EMBODIMENT oo
