Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift operating device in a moving vehicle having two steering positions, a forward steering position and a backward steering position.

2. Description of the Related Art Conventionally, some mobile vehicles used for agricultural work and the like have two steering positions, a forward steering position and a backward steering position, and the steering position is changed according to the work situation and the type of work. . In such a moving vehicle, one gear shift operation device is provided, and one gear shift operation lever is operated whether the gear shift operation is performed from the forward steering position or the rearward steering position. There is.

Problems to be Solved by the Invention The shift feeling of the shift operation lever differs between the case where the shift operation lever is operated from the forward steering position and the case where the shift operation lever is operated from the rearward steering position. Therefore, when changing the steering position, it is necessary to operate the shift operation lever while checking the shift position.
Gear shifting operations cannot be performed smoothly, and work efficiency is reduced. Further, there is a risk that the shift operation lever is erroneously operated because the shift operation lever feels different between the forward steering position and the backward steering position.

In a moving vehicle having two steering positions, a forward steering position and a rearward steering position which is opposite to the forward steering position, a gear shift operation lever is provided between these two steering positions. A shift position is provided at a position symmetrical with respect to the neutral position of the shift operating lever, in which the moving speed of the moving vehicle is equal and the moving direction of the moving vehicle is opposite.

Further, the forward pilot seat is provided in the forward pilot position, the rear pilot seat is provided in the rear pilot position, and a pair of control devices corresponding to these pilot seats are provided.

Action When operating a moving vehicle from the forward steering position and the rearward steering position, the shift operation lever shift feels the same, and the shift operation lever shift operation is performed even when the steering position is changed. The operation can be performed smoothly and erroneous operation of the shift operation lever can be prevented.

Further, the shift operation lever has the same shift feeling when the operator is seated in the front operator's seat and the operator is seated in the rear operator's seat. The gear shift operation can be performed smoothly, and erroneous operation of the gear shift operation lever can be prevented.

Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 and 2. First of all, one shift operation lever 1 is provided for a moving vehicle.
Is provided, a forward facing driver's seat 2 and a backward facing driver's seat 3 are provided at a position sandwiching the gear shift operation lever 1, and further, a control device is provided at a position facing the front of these driver's seats 2 and 3, respectively. Steering wheels 4 and 5 are provided. The frontward cockpit 2 is arranged toward the front (direction of arrow A) in the normal traveling direction of the moving vehicle, and the rearward facing cockpit 3 is rearward in the direction of normal traveling of the moving vehicle (direction of arrow B). ).

Next, the shift operation lever 1 is rotatably provided along a guide groove 7 formed in the guide plate 6. Here, the arrangement of the shift position of the shift operating lever 1 will be described with reference to FIG. Neutral position "N"
1st forward gear shift position "1" and 1st reverse gear shift position "R1" are arranged in a point-symmetrical position with respect to
Further, a forward 2nd speed shift position "2" and a reverse 2nd speed shift position "R2" are disposed at positions symmetrical with respect to the neutral position "N".

When the shift operation lever 1 is operated to shift to the first forward gear shift position “1” and the reverse first gear shift position “R1”, the shifting speed of the moving vehicle is the same and the moving direction of the moving vehicle is the same. Are set to be reversed.
Similarly, when the gear shift operation lever 1 is operated to shift to the second forward gear shift position "2" and the second reverse gear shift position "R2", the moving speed of the moving vehicle is equal and the moving vehicle moves. The direction is set to be opposite.

In such a configuration, when an operator is seated in the front-facing cockpit 2 for maneuvering, the shifting vehicle is rotated forward from the neutral position to the left front, so that the moving vehicle moves to the first forward speed as seen from the operator. The shift state is set, and the shift operation lever 1 is rotated rightward and rearward from the neutral position, so that the moving vehicle shifts to the reverse first speed as seen from the operator. Further, by rotating the gear shift operation lever 1 from the neutral position to the left rear, the moving vehicle is in the second forward gear shift state as seen from the operator, and the gear shift operation lever 1 is rotated from the neutral position to the right front. As a result, the moving vehicle shifts to the second reverse speed as seen from the operator.

Next, when the operator is seated on the rearward cockpit 2 and is maneuvering, the gear shift operation lever 1 is rotated from the neutral position to the left front, so that the moving vehicle shifts to the first forward speed as seen from the operator. By rotating the gear shift operation lever 1 from the neutral position to the right rear, the moving vehicle is in the first reverse gear shift state when viewed from the operator. Further, by rotating the gear shift operation lever 1 from the neutral position to the left rear, the moving vehicle is in the second forward gear shift state as seen from the operator, and the gear shift operation lever 1 is rotated from the neutral position to the right front. As a result, the moving vehicle shifts to the second reverse speed as seen from the operator.

Therefore, the shift feeling of the gear shift operation lever 1 is the same when the operator is seated in the front cockpit 2 for maneuvering and is seated in the rear maneuver seat 3 for maneuvering. For this reason,
Even when the pilot seats 2 and 3 are changed and operated, the shift operation of the shift operation lever 1 can be performed smoothly and erroneous operation of the shift operation lever 1 due to a mistake can be prevented. In addition, a safety device is provided to restrict the shift operation of the shift operation lever 1 to the high-speed reverse shift position "R2".
By adopting a structure in which the moving vehicle cannot be steered unless the safety device is operated, the occurrence of an accident due to a shift operation to a high-speed reverse gear shift position by mistake is reliably prevented.

Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those described in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted. In the present embodiment, a shift position for forward 3rd speed and reverse 3rd speed is provided. The shift position "1" for forward 1st speed and the shift position "R1" for reverse 1st speed are centered on the neutral position "N". The two forward gear shift positions "2" and the two reverse gear shift positions "R2" are placed in symmetrical positions about the neutral position "N". The third-speed shift position "3" and the reverse third-speed shift position "R3" are arranged in a point-symmetrical position with the neutral position "N" as the neutral position.

With such a configuration, the shift feeling of the gear shift operation lever 1 is the same when sitting on the frontward cockpit 2 to operate the moving vehicle and when sitting on the rearward facing cockpit 3 to steer the moving vehicle. For example, when the gear shift operation lever 1 is rotated to the leftmost front side while seated in the front facing driver's seat 2, the moving vehicle shifts to the first forward speed as seen from the operator, and the seat in the rear facing driver's seat 3 When the gear shift operation lever 1 is pivotally operated to the leftmost front, the moving vehicle is in the first forward gear shift state when viewed from the operator. Therefore, the shift operation lever 1 has the same shift feeling when the operator is seated in the frontward pilot seat 2 and is maneuvered in the rearward pilot seat 3, and the gear shift operation lever is changed because the pilot seats 2 and 3 are changed. It is possible to prevent erroneous operation of 1.

In addition, when moving a vehicle into or out of the garage, it is possible to enter the garage in a forward state by sitting on the forward-facing cockpit 2 and steer it, and to move it forward while sitting on the rearward-facing cockpit 3. You can leave the garage at.

As described above, the present invention has the gear shift operation lever disposed between the two steering positions, the forward steering position and the rearward steering position, and is located at a position symmetrical about the neutral position of the gear shifting operation lever. In the case where the moving vehicle is steered from the forward steering position and the backward steering position by providing the shift position in which the moving speeds of the moving vehicle are equal and the moving direction of the moving vehicle is opposite, The shift operation lever has the same shift feeling, and even when maneuvering while changing the steering position, the shift operation lever can be smoothly operated to improve work efficiency and prevent incorrect operation of the shift operation lever. It is possible,
Furthermore, by installing a pair of control devices corresponding to the front cockpit provided in the forward pilot position and the rear cockpit located in the rear pilot position, it is possible to use the front pilot seat when operating while sitting in the front pilot seat and the rear pilot seat. Even when sitting and manipulating, the shift operation lever can be operated with the same shift feeling.
