In this way, the brake can be locked by operating the brake lock lever without operating the brake lever, and operability can be improved.

Hereinafter, this embodiment will be described in detail with reference to the accompanying drawings. FIG. 1 is an overall view of the brake device of this embodiment. Further, in the following figures, an arrow FR indicates the front of the vehicle, an arrow RE indicates the rear of the vehicle, an arrow L indicates the left side of the vehicle, and an arrow R indicates the right side of the vehicle.

As shown in FIG. 1, the brake device 1 operates such that a front brake operation device 2 operates a front brake device 3, and an interlocking brake operation device (brake operation device) 4 operates a front brake device 3 and a rear brake device 5. It is composed of The front brake device 3 is a hydraulic disc brake, and generates braking force on the front wheels (not shown) by pressing a brake pad 12 against a brake disc 11. The rear brake device 5 is a mechanical drum brake, and generates braking force to the rear wheels (not shown) by pressing brake shoes 16 against the brake drum 15.

A front brake device 3 is connected to a master cylinder 21 of the front brake operating device 2 through a hydraulic pipe 22 . A piston rod 23 is housed in the master cylinder 21, and a link lever 24 is provided at the tip of the piston rod 23 protruding from the master cylinder 21. A front brake lever 25 is connected to one end of the link lever 24, and operating hydraulic pressure is output from the master cylinder 21 to the hydraulic pipe 22 by operating the front brake lever 25. A front brake cable 26 is connected to the other end of the link lever 24, and working pressure is outputted from the master cylinder 21 to the hydraulic pipe 22 also by pulling the front brake cable 26.

An interlocking brake lever (brake lever) 50 is swingably supported on the lever holder 30 of the interlocking brake operating device 4, and an equalizer 70 (see FIG. 2) is swingably supported on the base end side of the interlocking brake lever 50. is supported by The equalizer 70 is connected to the front brake operating device 2 through a front brake cable 26 and to the rear brake device 5 through a rear brake cable 27. When the equalizer 70 is swung by operating the interlocking brake lever 50, the equalizer 70 pulls the front brake cable 26 and the rear brake cable 27, and the front brake device 3 and the rear brake device 5 are actuated.

Further, the interlocking brake operating device 4 is provided with a brake lock lever 60 to maintain the brake lock state during parking. When the brakes are locked, it is desirable that no hydraulic pressure is generated in the front brake device 3 in order to prevent troubles such as oil leakage from the front brake device 3. It is necessary to lock the interlocking brake lever 50 while pulling only the rear brake cable 27 without pulling the front brake cable 26. Various types of such brake lock structures have been proposed, but usually the interlocking brake lever and the brake lock lever must be operated separately.

Therefore, in this embodiment, the interlocking brake lever 50 and the equalizer 70 are simultaneously swung by operating the brake lock lever 60. The interlocking brake lever 50 is locked by the brake lock lever 60 in the brake operating state, and when the interlocking brake lever 50 is locked, the front brake cable 26 is not pulled by the equalizer 70, but only the rear brake cable 27 is pulled by the equalizer 70. . Thereby, without operating the interlocking brake lever 50, by operating the brake lock lever 60 once, the brake lock can be maintained in a state where only the rear brake device 5 is operated.

The detailed configuration of the interlocking brake operating device will be described below with reference to FIGS. 2 to 5. FIG. 2 is an exploded perspective view of the interlocking brake operating device of this embodiment. FIG. 3 is a top view and a right side view of the interlocking brake operating device of this embodiment.

As shown in FIGS. 2 to 4, the interlocking brake operating device 4 is attached to the handle 29 via a lever holder 30. The lever holder 30 has a cylindrical part 31 attached to the handle 29, a pair of upper and lower plate parts 32 to which the interlocking brake lever 50 is attached, and a block part 33 to which the brake cables 26 and 27 are held. . A slit 34 is formed in the lower surface of the cylindrical portion 31 along the axial direction. A tightening bolt 41 is provided on the lower surface of the cylindrical portion 31, and by tightening the tightening bolt 41, the interval between the slits 34 is narrowed, and the cylindrical portion 31 is tightened and fixed to the handle 29. There is.

A lever pivot hole 35 is formed in the pair of upper and lower plate portions 32, and a lever pivot hole 52 is formed at the base end side of the interlocking brake lever 50. The base end side of the interlocking brake lever 50 is inserted inside the pair of plate-shaped parts 32, and the lever pivot bolt 42 is inserted into the lever pivot hole 35 of the lever holder 30 and the lever pivot hole 52 of the interlocking brake lever 50. . By tightening the lever pivot nut 43 to the tip of the lever pivot bolt 42, the interlocking brake lever 50 is swingably supported by the lever holder 30 via the lever pivot bolt 42.

A holding hole 36 into which the front brake cable 26 is inserted and a holding hole 37 into which the rear brake cable 27 is inserted are formed in the block portion 33. A stopper 38 protrudes from the upper surface of the block portion 33, and the stopper 38 restricts the clockwise swinging of the interlocking brake lever 50. The inner surface of the block portion 33 is a restriction surface 39 that restricts the clockwise swinging of the brake lock lever 60 and the equalizer 70. The stopper 38 and the regulating surface 39 determine the initial positions of the interlocking brake lever 50, the brake lock lever 60, and the equalizer 70 when the levers are not operated.

A pair of upper and lower plate portions 51 that can accommodate the base end of the brake lock lever 60 are formed on the base end side of the interlocking brake lever 50, and upper and lower plate portions 51 that can accommodate the equalizer 70 are formed on the base end side of the brake lock lever 60. A pair of plate-shaped portions 61 are formed. The above-mentioned lever pivot hole 52 is formed on the rear side of the pair of plate-like parts 51 of the interlocking brake lever 50, and an equalizer pivot hole 53 is formed on the front side of the pair of plate-like parts 51. Further, an equalizer pivot hole 63 is formed in the pair of plate-like portions 61 of the brake lock lever 60, and an equalizer pivot hole 73 is formed in the center of the equalizer 70.

A pair of plate-like parts 61 of a brake lock lever 60 are inserted inside the pair of plate-like parts 51 of the interlocking brake lever 50, and an equalizer 70 is inserted inside the pair of plate-like parts 61 of the brake lock lever 60. I'm here. Equalizer pivot bolts 75 are inserted into the equalizer pivot holes 53, 63, and 73 of the interlocking brake lever 50, the brake lock lever 60, and the equalizer 70. By tightening the equalizer pivot nut 76 to the tip of the equalizer pivot bolt 75, the brake lock lever 60 and the equalizer 70 are swingably supported by the interlocking brake lever 50 via the equalizer pivot bolt 75.

A pair of operation parts 64 (see especially FIG. 5) are provided on the left side of the pair of plate-like parts 61 of the brake lock lever 60. The pair of operation parts 64 push the rear side of the equalizer 70 into the lever holder 30 side, and swing the equalizer 70 counterclockwise with respect to the interlocking brake lever 50 using the equalizer pivot bolt 75 as a fulcrum. The right corner portions of the pair of plate-shaped portions 61 are protrusions (latching portions) 65 for latching the brake lock lever 60 to the lever holder 30. In this manner, the brake lock lever 60 has the operating portion 64 located at the rear in the swinging direction of the equalizer 70, and the protrusion 65 located at the front in the swinging direction of the equalizer 70.

When the protrusion 65 of the brake lock lever 60 is pushed back against the regulating surface 39 of the lever holder 30, the brake lock lever 60 and the interlocking brake lever 50 are swung counterclockwise around the lever pivot bolt 42 ( (See Figure 7). Further, the lever holder 30 is formed with a recess (latching portion) 45 on which the protrusion 65 is hooked (see FIG. 3(A)). By latching the protrusion 65 of the brake lock lever 60 to the recess 45 of the lever holder 30, the interlocking brake lever 50 is locked while the brake is being operated. The recess 45 and the protrusion 65 determine the lock position at which the brake is locked.

More specifically, the protrusion 65 of the brake lock lever 60 and the recess 45 of the lever holder 30 are formed into a substantially triangular shape when viewed from above. The shape of the recess 45 is such that the protrusion 65 can be latched in a counterclockwise swinging direction with the equalizer pivot bolt 75 as a fulcrum, and the protrusion 65 can be latched in a counterclockwise swinging direction with the lever pivot bolt 42 as a fulcrum. 65 is formed so that it can be removed. Therefore, when the brake lock lever 60 is operated, the protrusion 65 is latched to the recess 45 and the brake is locked, and when the interlocking brake lever 50 is operated counterclockwise, the protrusion 65 is disengaged from the recess 45 and the return spring 77 is released. The force releases the brake lock.

The equalizer 70 is formed into a rectangular shape with rounded corners when viewed from above and has three connecting portions. A front connecting part 71 to which the front brake cable 26 is connected is formed on the rear side of the equalizer 70, and a rear connecting part 72 to which the rear brake cable 27 is connected is formed in the front side of the equalizer 70. The equalizer pivot hole 73, which is connected to the interlocking brake lever 50 and the brake lock lever 60, is formed between the front connecting portion 71 and the rear connecting portion 72 as an intermediate connecting portion. In response to the operation of the interlocking brake lever 50, the equalizer 70 pulls the front brake cable 26 and the rear brake cable 27.

The equalizer pivot bolt 75 is provided with a return spring 77 that provides the brake lock lever 60 with a repulsive force against lever operation. One end of the return spring 77 is supported by the interlocking brake lever 50, and the other end of the return spring 77 is supported by the brake lock lever 60. The brake lock lever 60 is pressed against the regulating surface 39 of the lever holder 30 by the repulsive force of the return spring 77. The right side of the pair of plate-shaped portions 61 of the brake lock lever 60 and the right side of the equalizer 70 abut against the regulating surface 39, and the brake lock lever 60 and the equalizer 70 are positioned in the lever holder 30 with high precision.

In this interlocking brake operating device 4, a brake lock lever 60 is housed in an interlocking brake lever 50, an equalizer 70 is housed in the brake lock lever 60, and the interlocking brake lever 50 and the brake lock lever 60 are directly connected to the equalizer 70. . Further, a locking structure is formed on the lever holder 30 and the brake lock lever 60, but a locking structure is not formed on the interlocking brake lever 50 and the equalizer 70. As a result, the interlocking brake operating device 4 is formed compactly, and the degree of freedom in layout of the interlocking brake operating device 4 is improved. Furthermore, the equalizer 70 is protected with a minimum number of parts, reducing costs.

Further, in the interlocking brake operating device 4, the interlocking brake lever 50 is swung counterclockwise relative to the lever holder 30 by operating the brake lock lever 60, and the equalizer 70 is oscillated counterclockwise relative to the interlocking brake lever 50. be swayed. Then, the protrusion 65 of the brake lock lever 60 is latched to the recess 45 of the lever holder 30, and the pair of operating parts 64 is used to set the equalizer at a position where the front brake cable 26 is not pulled and the rear brake cable 27 is pulled. 70 is located. As a result, the brakes are locked with only the rear brake device 5 being operated.

In this case, as shown in FIG. 5, the pair of operating parts 64 of the brake lock lever 60 are formed so as to come into contact with the front connecting part 71 of the equalizer 70 from behind in the swinging direction. When the brake lock lever 60 is operated, the front connecting portion 71 is pushed in from the rear by the pair of operating portions 64. Even if the entire equalizer 70 is separated from the regulating surface 39 by the swinging of the interlocking brake lever 50 (see FIG. 3(A)), the front connecting portion 71 is moved away from the regulating surface 39 by the swinging of the equalizer 70 with the equalizer pivot bolt 75 as a fulcrum. You can get closer to 39. The front connecting portion 71 does not move from its substantially original standby position, and the pulling of the front brake cable 26 by the equalizer 70 is suppressed.

Note that the towed state refers to a state in which the brake cable is towed and the brake device is activated. The non-traction state is not limited to a state in which the brake cable is not completely towed, but includes a state in which the brake cable is towed with such weak force that the brake device does not operate. In this embodiment, since the front brake cable 26 is in the non-traction state, the piston rod 23 of the master cylinder 21 (see FIG. 1) is not moved significantly via the front brake cable 26. Therefore, the working pressure is not output from the master cylinder 21 to the hydraulic piping 22, and oil leakage from the hydraulic piping 22 and deterioration of the life of the rubber parts are suppressed.

The brake lock operation of the interlocking brake operation device will be described with reference to FIGS. 6 to 9. FIG. 6 is a diagram showing a non-operated state of the brake lock lever of this embodiment. FIG. 7 is a diagram showing the operating state of the brake lock lever of this embodiment.

Further, the brake lock lever 60 and the equalizer 70 are pressed against the regulating surface 39 of the lever holder 30 due to the tension of the front brake cable 26 and the rear brake cable 27 . When the brake lock lever 60 is not operated, the side 62 of the brake lock lever 60 is pressed against the regulation surface 39, and the brake lock lever 60 is positioned at the initial position A1.

A contact surface 54 is formed on the inner side of the interlocking brake lever 50, with which a pair of operating portions 64 of the brake lock lever 60 come into contact. When the brake lock lever 60 is positioned at the initial position A1, the brake lock lever 60 is sandwiched between the regulating surface 39 of the lever holder 30 and the contact surface 54 of the interlocking brake lever 50. The pair of operation parts 64 are pressed against the contact surface 54 and are spaced apart from the equalizer 70. Therefore, when operating the brake lock lever 60, the brake lock lever 60 is swung relative to the equalizer 70 until the pair of operating parts 64 come into contact with the equalizer 70.

As shown in FIG. 7, when the brake lock lever 60 is operated counterclockwise against the repulsive force of the return spring 77 (see FIG. comes into contact with the regulating surface 39 of. The protrusion 65 of the brake lock lever 60 is pushed back by the restriction surface 39, and the interlocking brake lever 50 connected to the brake lock lever 60 is swung counterclockwise about the lever pivot bolt 42. When the pair of operating parts 64 come into contact with the front connecting part 71 of the equalizer 70, the front connecting part 71 is pushed in by the pair of operating parts 64, and the equalizer 70 swings counterclockwise about the equalizer pivot bolt 75. be done.

As shown in FIG. 8, when the brake lock lever 60 is further operated counterclockwise, the protrusion 65 of the brake lock lever 60 enters the recess 45 of the lever holder 30, and the brake lock lever 60 is positioned at the lock position A2. be done. A repulsive force is acting on the brake lock lever 60 from the return spring 77 (see FIG. 2), but the brake lock lever 60 is latched to the lever holder 30 due to the tension of the rear brake cable 27, and the equalizer pivot bolt 75 is Swinging of the brake lock lever 60, which is used as a fulcrum, is restricted. As a result, the interlocking brake lever 50 connected to the brake lock lever 60 is locked in the brake operating state.

When the brake is locked, the equalizer 70 is swung counterclockwise using the lever pivot bolt 42 as a fulcrum. has hardly moved from its original standby position. Therefore, the front brake cable 26 is not pulled by the front connection part 71, but the rear brake cable 27 is pulled by the rear connection part 72. In this manner, by operating the brake lock lever 60, the brakes are locked with the front brake device 3 not operating and only the rear brake device 5 operating.

As shown in FIG. 9, when the brake lock is released, the interlocking brake lever 50 is operated counterclockwise. The interlocking brake lever 50, brake lock lever 60, and equalizer 70 are integrally swung counterclockwise around the lever pivot bolt 42, and the protrusion 65 of the brake lock lever 60 and the recess 45 of the lever holder 30 are latched. is canceled. The brake lock lever 60 is swung clockwise around the equalizer pivot bolt 75 by the repulsive force of the return spring 77 (see FIG. 2). Further, the interlocking brake lever 50 is swung clockwise around the lever pivot bolt 42 by the tensile force of the rear brake cable 27.

The brake lock lever 60 and the equalizer 70 contact the regulating surface 39 of the lever holder 30, and the interlocking brake lever 50 contacts the stopper 38 of the lever holder 30, returning the brake lock lever 60 to the non-operating state. The rear brake cable 27 is not pulled by the equalizer 70, the operation of the rear brake device 5 is stopped, and the brake lock state is released. In this way, when the brake is locked, the brake can be locked by a single operation of the brake lock lever 60, and when the brake is unlocked, the brake can be unlocked by a single operation of the interlocking brake lever 50.

As described above, according to the present embodiment, the interlocking brake lever 50 is swung relative to the lever holder 30 by the brake lock lever 60, and the equalizer 70 is oscillated relative to the interlocking brake lever 50 by the operating section 64 of the brake lock lever 60. be swayed. When the interlocking brake lever 50 is locked, the equalizer 70 does not pull the front brake cable 26 but the rear brake cable 27. This allows the brake lock to be maintained while only the rear brake is operated. By operating the brake lock lever 60 without operating the interlocking brake lever 50, the brake can be locked while the rear brake is activated, and the operability of the interlocking brake operating device 4 can be improved. .
