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

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

With reference to Fig. 2, Fig. 6 and Fig. 8, under " original state ", brake pedal 56 by the drawing force of resetting spring 59 and by The direction rotated to the counter clockwise direction A centered on pedal pivot 91 into figure exerts a force.In this condition, by making working arm The rear side retainer 77 that retainer abutting part 95 and the back seat in portion 94 trample board mount 43R abuts, 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, under " original state ", balance element 61 is supported by postponing the drawing force quilt of spring 64 to balance element The direction force that A is rotated counterclockwise centered on axis 96, when being observed in side, balance element 61 is in and leans forward than vertical direction State.In this condition, 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 low after preceding height when side is observed State, the abutting part 107 are supported by postponing the active force of spring 64 and the front portion from below with the lower surface of rotatable parts 88b Connect.Here, delay spring 64 has been mounted in the state of defined initial load has been applied in.Therefore, as long as no work With the load more than above-mentioned initial 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.It is to make the work opportunity of front wheel brake work department 53 relative to trailing wheel to postpone spring 64 The component that the work opportunity in braking operation portion 57 postpones and sets.

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 resetting 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 as the fulcrum of 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 Direction that weighing apparatus part support shaft 96 is moved forwards centered on the abutting part that abutting part 107 is abutted with rotatable parts 88b, i.e. with turn Counter clockwise direction A centered on dynamic component 88b is rotated.Thus, brake bar 58 is drawn via rear service brake operation arm 102 Forwards, rear service brake work department 57 (Fig. 1) works, so as to be braked to trailing wheel 3.

On the other hand, in 101 side of front wheel brake operation arm, " rear service brake of the balance element 61 in " original state " to Fig. 8 Only it is to be moved while abutting part 107 is slided relative to rotatable parts 88b 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) will not work.

Specifically, although abutting part 107 under " original state " when side is observed in it is preceding it is high after low state and Abutted with the lower surface of rotatable parts 88b, but the operating quantity of brake pedal 56 more increases, then and the abutting part 107 more becomes and more connects The posture of nearly vertical side.Moreover, with the operating quantity increase of brake pedal 56,107 edge of abutting part under " rear service brake state " The slip of rotatable parts 88b forward upwards, is moved in a manner of the more forwardly of face side with rotatable parts 88b abuts.

Due to initial position retainer 63 the peripheral part for forming initial position retainer 63 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 accuracy and slide glibly.

In the present embodiment, even possessing 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 trailing wheel 3 to rear service brake position RB is reached.

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

From " rear service brake state " further increase brake pedal 56 operating quantity when, front and back linkage arrestment mechanism 60 into " 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 reaches linkage application position CB more than ormal weight from rear service brake position RB, 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 significantly 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, being acted on delay spring 64 has More than the load of above-mentioned initial load.Thus, delay spring 64 extends forwards, 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 by the interior lines for the brake cable 62 that links Cable 62b pulls to front, and thus, front wheel brake work department 53 works.Therefore, front-wheel 2 is braked.

In fig. 9 it is shown that the track L of the cable connections 104 with the operation of brake pedal 56.From " initial shape To " rear service brake state ", track L is moved upward state " in a manner of not pulling up linkage brake cable 62 in operation side, When as " linkage on-position ", track L by pulled up in operation side linkage brake cable 62 in a manner of significantly Move forwards.

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

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