JPS6047731A - Link mechanism of traveling clutch and brake for traveling car - Google Patents

Abstract

PURPOSE:To facilitate clutch switching operation and brake operation by operating a brake mechanism for applying brake onto a belt or the pulley of the belt, linked with the operation of a clutch operating member which performs tightening and relaxing operation for the belt. CONSTITUTION:When a traveling clutch C1 is set IN, the tension pulley 8 of a tension arm 7 is pressed by a belt 4, and an engine pulley 2 and an input pulley 3 are set into power transmission state. Since the pin 25 of the arm 7 pushes the collar part 22b of a brake rod 22, a brake holder 19 turns, and a brake shoe 26 is separated from the input pulley 3, and brake is released. When the traveling clutch mechanism C1 is set OFF, the pin 25 is separated from the collar part 22n. Therefore, the brake holder 19 is turned in the direction of operation by the urging force of a brake spring 36, and brake is applied.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to loosening of a belt, 51 (operating on/off a latch for running by tightening) and braking a belt or an input pulley in a running vehicle. This relates to the interlocking transmission between the latch and brake.

When parking, you must not only disengage the running latch, but also apply the brakes, but if the clutch disengages and the vehicle stalls, do you operate the brakes? Sometimes I forget. Also, when driving downhill on a slope 2, the driving latch is turned off and the brakes are applied as appropriate, but this clutch release operation and brake operation Y
If row 9 can be performed with the operating member of bl, the operation will be easy.

Therefore, the present invention is devised so that the clutch disengagement operation and the brake operation can be performed easily, and the following technical means 3 are implemented.

That is, engine boo +) (21-trace h 'a m'j
11111 (D) Loosely wrap r'T between the manual pulley (81) and the belt (shoulder tension/relaxation action, clutch operation member (91)
) (ol), a brake machine (!I\ (B1)) that brakes the input pulley (8) or belt (4),
The latch operation (C□) carried out by the clutch operating member (9) and the braking operation of the brake machine 47 (8) are performed in conjunction with the 1st movement.・This is the 43rd generation of interlocking transmission between the latch and the brake that allows the vehicle to run at constant speed.

This invention has obtained the following technical effects by the above-mentioned borrowing.

Immediately, in conjunction with the cutting operation of the running latch mechanism (C1) by the clutch operating member (9), the interlocking mechanism @ (t<1) works to slow down the braking operation of the brake mechanism (B1). So,
If you perform the stop operation, there is no danger of forgetting the braking action.
As a result, the procedure for parking has become perfect. Since this procedure is performed by operating one clutch operating section (9), the operation is easy.

Next, the second invention uses a clutch operating member (9) to tension and relax the RF belt (→) between the engine pulley (21) and the manual pulley (3) on the traveling mechanism side. Latch violation 47 (((I2)s)
(Cs) and manual pulley (8) or bell) [4]'r
Brake loading (B2) for braking - (latch transmission (mouth Z) running to 83 months - (aS) cutting area 71!
- When operating the clutch operating member (91), the interlocking mechanism (#(KJ-(K3)l2) is activated so that the braking operation of the brake machine 'D?(BJ, (B,)) is performed. This technology is a combination of the three mechanisms used to link the latch and brake of a running vehicle, and has achieved a different technical effect.

That is, if you operate the clutch operating member (9), first disconnect the latch i'KOJb (01) for running, and then operate this clutch operating member (9) beyond the disconnecting range.
The clutch operating member (9) can now easily perform the operation of keeping the brake steady (9) and loosening it.

Next, this invention Y will be explained based on the embodiments shown.

A mobile threshing machine is attached to the traveling vehicle shown in side view t and υ in Fig. 1. Fig. 2 (a) shows the main part of the machine as seen from the side, and Fig. 3 (= its back side view). FIG. 4 shows a plan view of FIG. 8, showing an embodiment of the first invention, which includes an engine pulley (2) attached to the crankshaft of the engine (11), and a running section [2].
Loosely wrap the belt (4.1) between the input 1i (11) of the traveling gear shift rocker 1 (not shown) and the manual pulley (3) to drive the vehicle body rocker frame (5). ) to the fulcrum width + (the tension pulley (81) of the tension arm (7) pivotally supported at I1, and the clutch operation member (91) is pressed against the bell [41 based on the rotation operation around the fulcrum pin 1ω, Alternatively, a latch KrQ (Ot) running away from the belt rod (117) is formed.

Illustrated running latch f? 14ftcOx) connects the clutch operating member (9) and one arm product) to the fulcrum bin α [(
Place the pin υ piece on the first layer of the arm, place the lower part of the rod (I4) on the lower part of the rod (I4), and the end of the tension arm (7) (the reverse 10! l of the tension pulley (8) pivot). )
The clutch operating member (9) comes into contact with mJ Ck of the guide groove of the continuous bar guide 06) via the two springs 5, and the rod α is pulled up.
The spring t151 rotates the tension arm (7) clockwise, and the belt (4) is tensed by the tension pulley (81), and the input pulley (river) is driven by the clutch. When the operating member (91 is turned to the left and the lever guide σ6) is moved to the clutch disengaged position where it touches the edge of the guide groove, the rod (14) moves downward and the return spring (17 ) according to the text 7-m [

Brake machine +: a(n,) pivots the brake holder σ9) on the vehicle body frame (5) at the fulcrum pin O), and attaches the brake rod to t211. Insert the threaded part (22a) of the brake rod into the 7" L/- key holder (ID) by loosely inserting the bottle into the 7" L/-key holder (ID), and insert the nut hole so that it can be held from both sides of the 1-size bottle.
Screw it into the jaw-threaded part (22a), insert the brake spring (to) between the flange part (2213) of the brake rod protrusion and the bracket bend, and! '! Clutch Hitomi as shown in Figure 8]
When the tension arm (71) is located in the original position, the brake rod (71) installed in the tension arm (7) pushes the flange (frlK22b), so the brake rod 1
The layer is the brake spring (c) fully compressed and enters the coupler ill.
The brake holder (r) rotates in the direction in which the blade is released, and the brake shoe (rotated) attached to the brake holder (σ9) is detached from the input pulley (8), causing the brake to loosen. When the situation occurs and the tension arm (71) is placed in the clutch position as shown in Figure 2 (a),
Brake pin (to) is flange (22b) > La Pe1fn
The brake spring (to) moves the brake rod to the left in the figure, the brake holder rotates counterclockwise, and the brake shoe moves to the position shown in figure 2 (b).

The first stage operation of the clutch retaining member (9) (2) is used as a source for clutch disconnection and pasting, and the other operations C and R are used to perform braking operation. Also, Fig. 8 ( This is an auxiliary cover that covers the side of the cuff pulley with code o3a.And, as in each embodiment of the second invention described above, (2. Belt+alt4'F pressure is applied to fB!I movement). (82), (B,) is the belt (4) for the brake.
Since a large frictional force is generated between the brake shoes and the brake shoes, a special lining material'? : There is no need to attach it to one brake member, and the brake member itself can be used as one brake shoe, so the manufacturing cost is low. In addition to the illustrated examples, the lead d can be replaced with other four-fold parts with the same function as these.
