この考案は動力車両、特にオルガン式ペダル構
造を有する産業車両のペダル構造に関する。[Detailed Description of the Invention] This invention relates to a pedal structure for a power vehicle, particularly an industrial vehicle having an organ-type pedal structure.
動力車両のクラツチペダルの方式には吊下げ式
が多く採用されていた。このものでは広い範囲の
ペダルストロークの中でペダル操作をすることか
ら割合いに楽なペダル制御が可能であつた。 Suspended clutch pedals were often used in power vehicles. With this device, the pedals were operated within a wide range of pedal strokes, making it possible to control the pedals relatively easily.

る。しかしこのものでは上記要望を満たすことが
できない。 However, in recent years, especially in industrial vehicles, the organ type has been increasingly adopted instead of the hanging type due to the restriction of attaching the operating valves, etc. of each part to the protector part of the mounting part. By the way, the fulcrum of this organ type pedal is provided on the toe board on the frame, and the total stroke is much smaller than that of the hanging type. Therefore, for vehicles such as forklift trucks that frequently operate the clutch half-way to move at slow speeds during cargo handling operations, the operation must be performed within a narrow stroke range and requires skill in pedal control. Was. In addition, power clutches are increasingly being installed to reduce the force on the pedals in order to reduce driver fatigue, and pedal control requires more and more skill, and ease of control is desired. . In addition, as in Japanese Patent Application Laid-Open No. 53-124831, a device is known in which a spring is provided to rapidly increase operating resistance during operation of the main clutch so as to perform the same function as a power transmission device equipped with a two-stage clutch. . However, this product cannot meet the above requirements.
従つてこの考案は上記の点に鑑みなされたもの
であつて、狭い範囲のストローク内で半クラツチ

となるようにそれぞれのゴム厚として、ペダル操
作時にゴムの圧縮抵抗より半クラツチ状態の感触
をうるようになしたものである。 Therefore, this invention was developed in view of the above points, and it is possible to control the pedal by considering the stroke range of a half-clutch and the stroke range of a disengaged clutch as a feel based on the amount of elastic deformation within a narrow stroke range. It is to provide a pedal structure that can be used. That is, a hard rubber and a soft rubber are laminated and fixed in the vertical direction on the back side of the pedal member or the toe board, and the installation gap is approximately equal to the play gap of the pedal, and the point where the feel of the rubber hardness changes is the clutch disengagement. The thickness of each rubber is such that when the pedal is operated, the compressive resistance of the rubber gives a feeling of a half-clutch state.

る。 Embodiments of this invention will be described below based on the drawings. When the industrial vehicle is a forklift, for example, a clutch pedal 1 is pivotally supported at its lower end by a pin 4 to a toe board 3 bolted to the upper surface of a frame 2, and a pedal plate 5 protrudes from the back surface of the toe board 3, and a clutch device. 7 is connected to the operating section 8 via a plurality of link members.

クラツチ状態に置かれる。 Accordingly, when the clutch pedal 1 is depressed, the clutch portion of the clutch device 7 is operated into a "half-clutch" or "clutch disengaged" state in accordance with the amount of depression. Further, a compression spring 6 is provided on the back surface of the pedal 1, and constantly urges the pedal 1 upward to maintain the "clutch engaged" state. The above-mentioned structure is conventionally known, and the important structure of this invention is the structure described below. That is, rubber 9 is baked or strongly adhered to the back surface of the clutch pedal 1 or the pedal plate 5 that protrudes from the back surface. This rubber 9 is a soft rubber 9 with low hardness that has a large amount of elastic deformation in response to the stepping force.
A is placed on the bottom, and a hard rubber 9b with a smaller amount of elastic deformation than the soft rubber with respect to the stepping force is placed on the top, and two types of rubber having different amounts of elastic deformation are stacked one on top of the other in two layers. It is constructed by baking or gluing them together. The lower surface of the soft rubber 9a is arranged to have a gap with the toe board 3 when it is attached to the pedal 1, and this gap approximately forms the play stroke B of the pedal 1. Therefore, in order to move the forklift to the cargo handling position and perform cargo handling work, the clutch pedal 1 is pressed.
When the pedal is depressed, the bottom surface of the soft rubber 9a contacts the toe board 3 at the end of the idle stroke B during the full stroke A of the pedal, and the soft rubber 9a comes into contact with the toe board 3 at the position where the pedal is depressed a little.
The elastic resistance a is felt as a tactile sensation on the driver's feet. From this position, the clutch is placed from a fully-contact condition to a half-clutch condition.

硬質ゴムの上下を逆にすることも自由である。 By continuing to press the pedal down, torque from the engine is transmitted to the drive shafts of the wheels, causing the vehicle to move forward at a slow speed, and cargo handling operations are carried out by performing inching operations based on this pressing position. As the amount of pedal depression increases, the amount of compression of the soft rubber 9a increases, the elastic resistance of the rubber increases, and the apparent hardness of the soft rubber 9a becomes equal to the hardness of the hard rubber 9b. If the pedal pressure is continued beyond this point (from the half-clutch stroke C to the clutch disengagement stroke D), elastic resistance of both rubbers 9a and 9b will be applied to the clutch pedal 1, indicating that the clutch has been disengaged. Judged by feel. Note that the rubber may be fixed to the toe board rather than to the pedal side, and a gap may be provided on the upper surface.Furthermore, the soft rubber and hard rubber may be turned upside down.

とは勿論である。 In this embodiment, a vehicle with a clutch has been described, but it goes without saying that the present invention can also be applied to a vehicle with a torque converter.

ことができる。 As detailed above, this idea consists of two layers of hard rubber and soft rubber on the back side of the pedal member of the clutch pedal or the toe board, with an installation gap approximately equal to the play gap of the pedal, and the thickness of each rubber specified.
Since the range in which the clutch is in the half-clutch state can be judged by feel, it is easy to operate the clutch within a small pedal stroke range such as with an organ type pedal, and fine control can be performed reliably. can. In addition, it can be stored compactly on the back side, making it possible to utilize space, and there are no restrictions on the undercarriage, so it is possible to work in a wide space. This can be done extremely easily without having to pay attention to this, and driving fatigue can be significantly reduced.
