The present invention relates to a passenger-type self-propelled vehicle, which is suitable as a vehicle capable of traveling where it is not stopped, such as an agricultural vehicle and a snowmobile (snowmobile).

In the conventional passenger car, the operation was possible only when the driver rides in the vehicle, and on the steep slopes and narrow hills, the driver must carry out the driving at risk and make pavement. Esau has shortcomings such as short travel and short stops, lifting and unloading cargoes, and inability to increase ergonomics.

The present invention aims to eliminate the above-mentioned shortcomings in the conventional passenger vehicle, and to provide a passenger vehicle in which a simple structure can be easily adjusted even when the vehicle is a walking type.

For this purpose, the passenger car of the present invention is designed to control the lung cancer and the steering wheel of the driver's seat, which are operated through the gratz shaft by a power control mechanism between the engine and the transmission device. In a self-propelled self-propelled self-propelled transport vehicle, in the above-mentioned self-propelled transport vehicle by operating the steering wheel and the power control mechanism outside the car, the handle and the power outside the car. The handle is disposed at a position where the bar of the vehicle can be manipulated so that the control of the green wine is finely controlled by operating the control mechanism. A steering wheel graticule, which can be manually driven through a tensioning spring, is arranged in an adjustable position outside the vehicle in the vicinity of the steering wheel.

According to the passenger car of the present invention, the power control mechanism interposed between the engine and the trans-mushion device is operated by a lung moon and an arm in the seat of the vehicle, and by a manual mover outside the vehicle. Because it can be operated, this manual lever can be operated near the directional steering wheel at the front end of the body that can be adjusted outside of the vehicle, and can be operated without any problems as a normal passenger vehicle. Of course, the driver can also drive while following the outside of the car, the power control mechanism and the steering wheel can be used both inside and outside of the vehicle, the structure is not complicated, the present invention is also an advantage.

In addition, according to the transport vehicle of the present invention, a hand grazier bar for operation outside the car is connected to a graci shaft interposed between a pedal arm operated in a transport seat and a power control mechanism through a tension spring, a lift and an arm. Therefore, even if the handle graticule is operated on the connecting shaft of the power control mechanism, the tension spring is tensioned without any trouble when the power interruption mechanism is stepped into the vehicle by stepping on the pedal moon and the arm. It is possible to drive the graci shaft, and when operating outside the vehicle, the operation of the above-mentioned power control mechanism is performed only by the hand and the graci lever.

Next, a description will be given of an agricultural passenger vehicle as an embodiment of the present invention by the accompanying drawings, in which FIG. 1 is a plan view thereof, FIG. 2 is a side view thereof, and FIG. 3 is a side view thereof showing another state thereof. The chassis is equipped with a front wheel (2) and a rear wheel (3) on both sides of the lower (lower) through a suitable suspension. (4) is an engine located on the front right side of the body and fixed on the chassis (1). Reference numeral 5 denotes a transmission device, which is located behind the engine 4, penetrates the chassis 1 up and down, and is fixed to the chassis 1 described above. Denoted at 6 is a shift lever protruding upward from the upper portion of the transmission device 5. (7) is a windshield located at the front end of the aircraft and stands upward over the full width of the aircraft, 8 is a steering wheel on the left front of the aircraft, and 9 is a steering wheel on the front (8). The driver's seat is located on the rear of the chassis and fixed on the chassis 1.

The pleasure 11 is fixed to the output side 910 of the engine 4, and the pleasure 11 is fixed to the input side 12 of the transmission device 95. The front 13 is fixed to the input side 12 of the transmission device 5. The belt 14 for transmitting the power of the engine 4 to the transmission device 5 is wound between the front 11 and the front 13. Reference numeral 15 denotes a propulsion side that transmits the power from the transmission device to the vehicle 93 behind through a suitable differential device. (16) is the grazing shaft which runs in the front lower position of the driver's seat (9), and runs substantially in the horizontal direction, both ends thereof by the stopper (17) protruding from the chassis (1). Rotation is supported freely.

Three arms, such as the lung moon, the arm 18, the lift arm 19, the tenshoner arm 20, and the like are projected to the graz shaft 16 in the direction perpendicular to the axis center. At the distal end of the tensioner arm 20, a tension free 21, which is positioned below the belt 14 and which lengthens or slows down the belt 14, is mounted as a rotating material. In addition, the manual hand grabber 922 located at the right front of the driver's seat 9 is provided at a position open to the outside of the vehicle near the handle 8, as shown in FIG. It is fixed to the hand grasp shaft 23 which comprised the axial center in the direction. The hand graticule shaft 23 is supported so as to be freely rotated by a locking device 24 extending from the upper rear side of the windshield 7.

In addition to the hand grasp lever 922, the arms 25 are fixed to the hand grasp shaft 23, and all of them move in a fan shape around the hand grasp shaft 23. As shown in FIG. (26) is a curved link, the upper end of which is pushed to the tip of the arm (25) by the pin (27), and the other end thereof is also pushed on one end of the tension spring (29) by the pin (28). . The other end of the tension spring 29 is squeezed to the tip of the lift arm 19 by a pin 30. Furthermore, it is a rear upper flower bed 31 of the chassis 1 located behind the body.

The power from the engine 4 is transmitted in the order of the output shaft 10, the pre 11 belt 14, the pre 13, and the input shaft 12, and enters the steering gear unit. The gearbox is shifted in the gearbox and is transmitted to the rear wheel 3 through a suitable differential in the propulsion shaft 15. Since the power transmission is interrupted between the engine 4 and the transmission device 5, it is composed of a wheel 11, a belt 14, a wheel 13, and a tension wheel 12. Graz mechanism is composed. That is, when the tension sensor 21 at the bottom of the belt 14 is integrated with the tension arm and rotates upwardly about the grazing shaft 16, the belt 14 is loaded with tension and is applied to the output shaft. Power transmission is performed through the belt 14 between the attached plate 11 and the plate 13 to which the transmission is attached. On the contrary, when the tension prie 21 moves downward, the belt 14 is stretched, and a slip is generated between the belt 14 and each of the prie 11 and 13, and the engine 4 Power transmission between the transmission device 5 is cut off.

In normal riding operation, the hand grasp lever 22 is turned over manually as shown in FIG. In this state, the tensile spring 29 is loaded with a tensile force. The tensile force attempts to rotate the graz shaft 16 in the direction of the arrow 32. As a result, the tension purge 21, which is freely supported on the tip of the tensioner arm 20, which is integrated with the gratic shaft 16 and moves in a fan shape, tries to move upwards. As a result, the belt Tension is imparted to (14) to allow power transmission between the engine 4 and the transmission device 5. This state is the same as that of Fig. 2, so that the pins 27, 28, the tension springs 29 and 30 are in a straight line, and the hand graticule shaft 23 is slightly in this straight line. Since the back spring has been reached, the tension springs 29 and 30 are in a straight line and attempt to rotate the hand graticule shaft 23 in the direction of the arrow 34. However, the hand grasp lever 22 fixed integrally with the above hand grasp shaft 23 faces the upper surface of the windbreak plate 7, and the hand grasp shaft 23 is located at or above the position shown in FIG. Is not rotated.

When the grazing mechanism is to be disconnected in this riding operation (half grazing), the pedal 18 may be stepped down with the foot. In other words, the tension moon arm 18, the tensioner arm 20, and the tensioner prism 21 supported at the tip of the tensioner arm 20 are integrally formed with the grazing shaft 16 as an axis to form a fan. When the pedal and arm 18 are pressed down, the grazing shaft 16 rotates in the direction of the arrow 33, and the tension sensor 21 is also moved downward, so that the engine 4 and the transmission mist device ( Power transmission is cut off with 5). (Or incomplete).

In the tension spring 29 which has already generated a tension force with the hand graticule lever lying on its front, the tension arm 19 protrudes in the direction of the arrow 33 while stepping down the lung cancer 18 downward. This results in drooping again. As described above, during the driving operation, the grazing operation is performed with the foot like a general car, and the steering operation is performed with the hand.

In the case of dangerous driving on hills and narrow cliff roads, or when cargo is carried out at low or low speeds when traveling short distances in fields or rice fields, the driver can get off the vehicle and walk the vehicle. .

Operation of the vehicle in the above case is carried out as follows.

The driver lays down the first handle grater lever 22 rearward as shown in FIG. 3, that is, the distance between the pin 25 and the pin 30 is shortened, and the tension spring 29 has its own tensile force. The loss of the graticule shaft 16 returns to the direction of the arrow 33 with the weight of the tensioner arm 20, the lift arm 19, the closing arm 18, and the like. As a result, the tension pre-21 which gives tension to the belt 14 moves downward, the belt 14 is struck, and power transmission between the engine 4 and the transmission device 5 is interrupted.

Next, the driver reverses the shift position of the transmission device 5, descends from the vehicle, stands in front of the windbreak plate 7, and causes the vehicle to reverse (backwardly) to start and drive. When the driver who descends the vehicle pulls the hand grasp lever that has fallen behind and pulls it down in front of him and puts it back to the second degree, it is as if the pedal 18 at the time of driving is not stepped on and the tension spring ( As a printing history of 29), tension tension 21 applies tension to belt 14, and power transmission between engine 4 and transmission device 5 starts, and the vehicle starts as a reverse. When the hand graticule lever 22 is laid on the rear side of the body again, power transmission is interrupted between the engine 4 and the transmission device 5, and the vehicle is stopped.

In this way, the driver can control the driving side of the vehicle by manipulating the round steering wheel 8 and the hand graticule lever 22 for walking.

Moreover, the handle 8 is provided near the hand grater lever 22, as is clear from the drawing, and is installed in a position where the driver can easily operate outside the car as a walking state.

As described above, as a passenger type carrier of the present invention, the steering wheel is placed at the front end of the vehicle, and is placed at the closest position of the graz lever arranged at a position that can be operated outside the vehicle, and at the same time, Since the operation system is divided into two types for a riding operation and two systems, the driver can safely drive while walking down a car on a dangerous hill road, a narrow cliff, and the like, in addition to the normal riding operation.

In addition, even in the case of the work area when the cargo must be dropped by moving a short distance, because the driving operation of the present invention can be operated while walking, there is an advantage of increasing the work efficiency while reducing the time and funeral of lifting.
