なる。The turning clutch C, which constitutes the clutch brake, is generally a friction clutch, and the friction plate F is strongly pinched by the elastic force of the engagement spring S. Therefore, when the steering operation is performed, the turning clutch C is disengaged as a front stage of the operation, and then the turning brake B is operated as a rear stage. However, since the engaging spring of the turning clutch C continues to operate in the front and rear stages of the operation, when the clutch C is released, the steering operation must be performed against it. ,
The operation became heavy and placed an extra burden on the driver. It is also known to use hydraulic pressure or electric power as a means for reducing the operating force, but such means is generally expensive and causes an increase in the price of the agricultural machine or the construction machine itself.

り操作が軽くなる。When the agricultural machine is steered, the operator commonly used for the turning clutch and turning brake operates by turning off the turning clutch before the operation and operating the turning brake after the operation. To stop the wheel axle. The operation of the front end is performed against the return spring of the turning clutch composed of the friction clutch, but when the turning clutch is in the disengaged state, the elastic force of the return spring is borne by the holding means and does not reach the operator. Therefore, in the operation of braking the turning brake, which is the operation of the rear stage, the driver does not have to bear the elastic force of the return spring that was acting during the operation of the turning clutch of the front stage, and if only the braking force is applied. As it improves, the steering operation becomes lighter.

に保持する。Reference numeral 38 is a clutch cam for disconnecting the turning clutch 30. The clutch cam 38 is composed of a rotating shaft rotatably supported by the drive case 21, and its axis is arranged so as to be orthogonal to the wheel shaft 16. The clutch cam 38 has a central portion of a first arm 61, which will be described later, attached to an end portion protruding outward from the drive case 21 so as to be non-rotatable and detachable via serrations, and one end thereof is an operation cable. 23 is connected to a steering operator (not shown) via other operation links. Then, the inner end portion remaining in the drive case 21 is formed by cutting off a part of the peripheral surface to form a cam having a substantially semicylindrical (semi-circular) cross section. Thus, when the clutch cam 38 is rotated by the operator, it is pushed to the left by the flange portion 56 formed at the rear end of the pressing member 36, and the pressing member 36 is pushed by the disc spring 37.
Against the resilience of the friction plates 33 and 34, the clamping force of the friction plates 33 and 34 is released to retreat and cut off the transmission of power. The clutch cam 3
The uncut cylindrical surface portion of the rotary shaft 8 forms a holding means 22 described later, and holds the turning clutch 30 in the disengaged state.

7 are arranged. Similar to the clutch cam 38, the braking cam 47 is composed of a rotating shaft rotatably supported by the drive case 21, and a portion protruding outward from the drive case 21 is steered via a second arm 62 described later. It is connected to the manipulator. That is, the turning brake 40 is connected to the operator common to the turning clutch 30. The braking cam 47 is a cam whose inner end portion remaining in the drive case 21 is formed by cutting off a part of the peripheral surface to form a semi-cylindrical cam having a substantially semicylindrical cross section, and the string portion thereof is normally the back surface of the pressing ring 46. Touches. Thus, when the braking cam 47 rotates, the contact point between the arc portion and the chord portion of the semicircular braking cam 47 moves, and the stop plate 43 is directed to the braking surface 41 via the pressing ring 46. To advance. On the other hand, on the wheel shaft 16, a cylindrical support shaft 48 having an involute spline on its outer peripheral surface is fitted to an angular shaft portion formed on the wheel shaft 16, and the braking friction plate 44 described above is provided on the outer periphery thereof. Spline engagement is performed only in the direction. Thus, when the braking cam 47 rotates, the stop plate 43 advances toward the braking surface 41, presses and stops the braking friction plate 44 arranged between them, and brakes the wheel shaft 16 connected thereto. .

The operation of will be described. When the steering operator is operated, first, when the first arm 61 is rotated counterclockwise from the initial position shown in (a) via the operation cable 23, the plane portion of the clutch cam 38 tilts, The flange 56 formed at the rear end of the pressing member 36 is moved to the left in the figure. As a result, the pressing surface 52 is separated from the friction plates 33 and 34, and the power transmission of the turning clutch 30 is interrupted. This state is shown in (b). Before the turning clutch 30 is completely disengaged, the bolt 63 screwed into the first arm 61 is attached to the receiving plate 64.
And the second arm 62 is rotated. Second arm 6
When 2 starts to rotate, the stop plate 43 and the braking friction plate 44 are gently braked.

When the state shown by (4) is reached, the turning clutch 30 is completely disengaged, and the uncut cylindrical surface portion of the rotating shaft forming the clutch cam 38 is formed at the rear end portion of the pressing member 36.
6 and thereafter, the reaction force of the disc spring 37 merely applies a bending force to the rotating shaft forming the clutch cam 38, and the action of rotating the clutch cam 38 in the direction of pushing back is lost. That is, it is understood that the reaction clutch opposing the operating force is lost, the turning clutch 30 is held in the disengaged state, and the clutch cam 38 itself constitutes the holding means 22.

Therefore, since the entire operating force can be used for operating the brake 40 thereafter, the operating force is reduced and the burden on the driver is reduced. Moreover, the structure for that purpose is as simple as setting the lift of the clutch cam 38 at the latter stage of the operation to zero, and is advantageous in that it can be constructed at low cost.
