Fig. 8 is to be changed front and back linkage arrestment mechanism 60 from " original state " using the operation of brake pedal 56 Figure.Here, in fig. 8, " original state " is illustrated with imaginary line.

In addition, showing " original state " of front and back linkage arrestment mechanism 60 in Fig. 2 and Fig. 6.

Referring to Fig. 2, Fig. 6 and Fig. 8, under " original state ", brake pedal 56 by the drawing force of reset spring 59 by The direction rotated to the counter clockwise direction A centered on pedal pivot 91 into figure exerts a force.In this state, by making working arm The retainer abutting part 95 in portion 94 is abutted with the rear side retainer 77 that back seat tramples board mount 43R, to limit brake pedal 56 Turned position, so that brake pedal 56 is in neutral position N (Fig. 8).Under " original state ", the axis of initial position retainer 63 Center 88c is located at than at the position on the front of balance element support shaft 96.

In addition, balance element 61 is supported by postponing the drawing force of spring 64 to balance element under " original state " The direction of A rotation exerts a force counterclockwise centered on axis 96, and when side is observed, balance element 61 is in and leans forward than vertical direction State.In this state, by making front wheel brake operate the abutting part 107 of arm 101 and turning for initial position retainer 63 Dynamic component 88b is abutted, and limits the turned position of balance element 61.

Specifically, under " original state ", the abutting part 107 of balance element 61 is when side is observed in the front is high and the back is low State, the abutting part 107 are supported by postponing front of the active force of spring 64 from below with the lower surface of rotatable parts 88b It connects.Here, delay spring 64 has been mounted in the state of being applied defined initial load.Therefore, as long as no work Be more than above-mentioned initial load load, then postponing spring 64 will not extend, thus balance element 61 be maintained at abutting part 107 with The state that rotatable parts 88b is abutted.Postponing spring 64 is to make the work opportunity of front wheel brake work department 53 relative to rear-wheel The work opportunity in braking operation portion 57 postpones and the component of setting.

As shown in figure 8, when driver steps on pallet body portion 93 and operates brake pedal 56, front and back linkage arrestment mechanism 60 become " the rear service brake state " that only rear service brake work department 57 works.

Under " rear service brake state ", brake pedal 56 be in overcome reset spring 59 and from neutral position N to clockwise Direction B rotated after rear service brake position RB, work arm 94 also B is rotated clockwise.With This, the balance element support shaft 96 of the fulcrum as balance element 61 moves forwards, therefore balance element 61 also moves forwards.

Specifically, under " rear service brake state ", effect does not have more than above-mentioned initial load on delay spring 64 Load, delay spring 64 from " original state " elongation.Therefore, under " rear service brake state ", balance element 61 is to making to put down Weighing apparatus part support shaft 96 moved forwards centered on the abutting part that abutting part 107 is abutted with rotatable parts 88b direction, i.e. with turn Counter clockwise direction A centered on dynamic component 88b is rotated.Brake bar 58 is drawn via rear service brake operation arm 102 as a result, Forwards, rear service brake work department 57 (Fig. 1) works, to brake to rear-wheel 3.

In contrast, 101 side of arm, " rear service brake of the balance element 61 in " original state " to Fig. 8 are operated in front wheel brake It is only to be moved while making abutting part 107 relative to rotatable parts 88b sliding between state ", cable connections 104 Position has almost no change on the draw direction of linkage brake cable 62.Therefore, under " rear service brake state ", linkage braking Cable 62 is not operated, and front wheel brake work department 53 (Fig. 1) not will do it work.

Specifically, although abutting part 107 under " original state " when side is observed in the state that the front is high and the back is low and It is abutted with the lower surface of rotatable parts 88b, but the operating quantity of brake pedal 56 more increases, then the abutting part 107 more becomes and more connects The posture of nearly vertical side.Moreover, as the operating quantity of brake pedal 56 increases under " rear service brake state ", 107 edge of abutting part Rotatable parts 88b forward upward sliding, moved in a manner of being abutted by the more forwardly of surface side with rotatable parts 88b.

Due to initial position retainer 63 composition initial position retainer 63 peripheral part rotatable parts 88b relative to Abutting part 107 rotates, therefore the initial position retainer 63 is small relative to the sliding friction of abutting part 107.Therefore, abutting part 107 can relative to initial position retainer 63 and high-precision and slide glibly.

In the present embodiment, even having the structure of front and back linkage arrestment mechanism 60, driver also can be by making The operating quantity of brake pedal 56 only brakes rear-wheel 3 to rear service brake position RB is reached.

In addition, by operating brake handle 52, front wheel brake work department 53 can be made opposite under " rear service brake state " It is operable independently from front and back linkage arrestment mechanism 60, to be braked to front-wheel 2.

When further increasing the operating quantity of brake pedal 56 from " rear service brake state ", front and back linkage arrestment mechanism 60 at " the linkage on-position " to work for rear service brake work department 57 and 53 both sides of front wheel brake work department.

Fig. 9 is the side view for showing " linkage on-position ".Here, in Fig. 9, " original state " and " rear service brake shape State " is illustrated with imaginary line.

When the operating quantity of brake pedal 56 is more than specified amount from rear service brake position RB and reaches linkage application position CB, Front and back linkage arrestment mechanism 60 becomes " linkage on-position ".

Under " linkage on-position ", the work arm 94 of brake pedal 56 is compared with " rear service brake state " and more substantially B is rotated clockwise on degree ground, and balance element 61 also moves forwards to a greater degree.

Under " linkage on-position ", by the increase of the operating quantity of brake pedal 56, acting on delay spring 64 has More than the load of above-mentioned initial load.Delay spring 64 extends forwards as a result, and abutting part 107 is abutted with rotatable parts 88b Balance element 61 leaves rotatable parts 88b and moves forwards, and front wheel brake operates arm 101 for the interior lines for the brake cable 62 that links Cable 62b pulls to front, and front wheel brake work department 53 works as a result,.Therefore, front-wheel 2 is braked.

In fig. 9 it is shown that the track L of the cable connections 104 along with the operation of brake pedal 56.From " initial shape State " to " rear service brake state ", track L not to be moved upward in such a way that operation side pulls up linkage brake cable 62, When becoming " linkage on-position ", track L by such a way that operation side pulls up and links brake cable 62 significantly It moves forwards.

In addition, under " linkage on-position ", rear service brake operates arm 102 compared with " rear service brake state " more substantially Degree ground moves forwards, therefore the amount of movement forwards of brake bar 58 increases, thus the brake force of rear service brake work department 57 with " rear service brake state " is compared and is increased.

It is abutted by the front side retainer 76f for making the leading edge potion of work arm 94 trample board mount 43R with back seat, to make The operating quantity of dynamic pedal 56 B (operative orientation of braking) clockwise is limited.

In addition, being held by the leading edge potion 101a for making the front wheel brake of balance element 61 operate arm 101 from rear and balance element It is abutted by portion 79, carrys out the amount of movement of the side forwards of limiting balance part 61.
