Description
BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a passenger type weaving machine comprising a submersible device mounted on a rear portion or a front portion of a traveling vehicle. More specifically, the present invention relates to a passenger-type rapier pedal that is performed by a shift pedal of a type in which a change of a traveling speed is stepped on.
In the case of an automobile such as a passenger car or a truck, the change of the vehicle speed is generally performed by adjusting the fuel injection amount. However, since the engine of the pasturing period not only runs but also drives the seedling plant, , So that the vehicle speed is changed by controlling the traveling change mission.
As an example thereof,
As shown in
However, in
When the traveling gas is suddenly accelerated or rapidly accelerated, the front portion of the traveling gas is lifted and the rear submersible unit is lowered, resulting in a problem that the depth of the seedling to the packaging surface is excessively deeper than a predetermined value. If it is suddenly or suddenly stopped, the traveling vehicle will be off to the side, and it will become easy to steer.
Further, as in
An object of the present invention is to solve the problem of these shifts in the passenger type rapper.
The present invention has a multi-faceted expansion. A first aspect of the present invention is a structure of the most advanced concept, and has a traveling vehicle on which an engine is mounted and a submersible device mounted on the rear portion of the traveling vehicle so as to be adjustable in height, And a step-variable shifting pedal for changing the speed of travel is provided in the traveling speed change mission, wherein the traveling speed change mission is provided with a traveling wheel, a transmission for transmitting the power of the engine to the traveling road wheel, Control is performed by a power type actuator that operates in response to the movement of the pedal.
According to a second aspect of the present invention, in the first aspect of the invention, there is provided a detecting means for detecting a stepping motion and a returning motion of the speed change pedal as electric signals, and the detecting means and the actuator are configured such that, The actuator accelerates the traveling speed change mission, and if the detecting means detects the return movement of the speed change pedal, the actuator interlocks with the driving speed change mission so as to decelerate.
According to a third aspect of the present invention, in the second aspect of the present invention, the detecting means can detect the amount of movement per unit time of the speed change pedal, while the actuator can control the traveling change mission so as to adjust the vehicle speed change per unit time, Between the means and the actuator, a controller capable of adjusting the relationship between the amount of movement of the speed change pedal per unit time and the rate of change of the vehicle speed is interposed.
According to the fourth invention, in the first to third inventions, an electric motor is employed as the actuator.
A fifth invention is a sub-concept of the first to fourth inventions, and is characterized in that, in addition to the first to fourth inventions, a brake mechanism for imparting a resistance to the rotation of the running wheels and an output of the running shift mission are connected to the running wheels And an operating member for switching the brake mechanism and the clutch mechanism simultaneously, wherein the operating member is in a running stop state in which the clutch mechanism is turned off by turning the brake mechanism ON, The brake mechanism can be turned OFF and the clutch mechanism can be turned ON to switch to the running state. In the fifth aspect of the present invention, in a state in which the operating member and the speed change pedal are not stepped on the speed change pedal, the operating member is in a stopped state, and in a state in which the operating member is in a running state, have.
According to a sixth aspect of the present invention according to the fifth aspect of the present invention, in the fifth aspect of the present invention, when the brake pedal is stepped on, the brake pedal and the operating member are provided with a brake pedal Interrupts the relationship and interlocks it so that it is in a stop state.
(Effects of the Invention)
In the first invention, since the movement of the speed change pedal is transmitted to the travel speed change mission through the power type actuator, it is possible to prevent the travel speed change mission from responding sensitively to the movement of the speed change pedal. Therefore, it is possible to prevent a sudden acceleration or a rapid acceleration due to depression of the speed change pedal, and as a result, it is possible to prevent the traveling gas from being tilted forward and prevent the seedling from being deeply implanted. In addition, since the sudden stop or the rapid deceleration of the shift pedal can be prevented by the return movement of the transmission pedal, it is possible to prevent or significantly reduce the traveling of the traveling gas to the side.
In addition, since the load and the impact at the time of shifting operation of the shift lever in the shift transmission mission are not transmitted to the speed change pedal as a so-called kickback, the shifting operability and the driving feeling can be greatly improved.
Although the movement of the transmission pedal can be transmitted to the actuator by a mechanical mechanism, the use of the electrical detection means as in the second invention is advantageous in terms of design since the interlocking member is unnecessary.
According to the third aspect of the invention, for example, it is possible to reduce the speed increase rate at the initial stage of the pedal depression operation (at the time of oscillation) or decrease the deceleration rate (decrease) at the end of the depression release operation of the speed change pedal It is possible to smoothly change the speed of the traveling vehicle so that the traveling vehicle can be stably driven. As a result, it is possible to prevent an effect of being deeply implanted, You can encourage.
As the actuator, various types such as a hydraulic motor and an electromagnetic solenoid can be used. However, if an electric motor (preferably a stepping motor) is employed as in the fourth invention, a simple structure and a complicated control are possible. Therefore, the fourth invention is a form suitable for the present invention.
According to the fifth aspect of the present invention, when the operator releases his / her foot from the speed change pedal, the clutch mechanism is turned OFF to stop the transmission of power to the traveling wheels and the brake mechanism is turned ON to stop the rotation of the traveling wheels. So that the operability of the rice plant can be improved.
In the planting work, it may be necessary to make a sudden stoppage in packaging because of safety. According to the sixth aspect of the present invention, when the brake pedal is depressed, the running vehicle suddenly stops in priority to the operation of the speed change pedal, so that the operability can be further improved.
