FIELD
The present disclosure relates to the field of arrangements for operating multiple systems in vehicles.DEFINITIONS
As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicate otherwise.
System – The term “system” hereinafter in the complete specification refers to various systems working independently or in collaboration in a vehicle, particularly in a tractor. The system includes, but not limited to, a gearbox, a creeper system, power take-off system, and an engine of a tractor.
BACKGROUND
In vehicles, particularly in tractors, multiple levers are employed for operating multiple systems. For example, a gear lever is provided to operate a gearbox of tractors, a power take-off lever is provided for operating a power take-off shaft of tractors, a creeper lever is provided for operating a creeper system, and the like. Such levers are usually provided in the driver cabin of tractors. However, more number of levers occupies more space in the cabin and makes the cabin look unaesthetic. Further, multiple levers create confusion for an operator especially when the operator has to operate multiple levers in a short span of time.
Therefore, there is felt a need of an arrangement that alleviates the abovementioned drawbacks, and can operate two systems.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
An object of the present disclosure is to provide an arrangement that operates two systems in a vehicle.

DETAILED DESCRIPTION
The present disclosure envisages an arrangement for operating two systems in a vehicle. The arrangement reduces number of levers in the driver cabin of a vehicle.
The arrangement of the present disclosure is now described with reference to Figure 1 through Figure 4. Figure 1 illustrates an isometric view depicting an arrangement 100, in accordance with an embodiment of the present disclosure. Figure 2 illustrates a cross sectional view of a lever of the arrangement 100. Figure 3 illustrates a front view of the lever. Figure 4 illustrates an isometric view of the lever.
The arrangement 100 comprises a lever 105. The lever 105 has a hollow configuration which defines a passage 110. The lever 105 is coupled to a first system (not specifically shown in figures). The lever 105 is configured to be displaced in predetermined directions to operate the first system.
In an embodiment, the first system is a gearbox (not specifically shown in figures) of a tractor. The lever 105 is a gear shifting lever of the gearbox. More specifically, the lever 105 is coupled to the gearbox via a differential housing 102. However, the scope of the first system envisaged in the present disclosure is not limited to the gearbox. Any other system can be operated using the lever 105 with appropriate modifications.
In an embodiment, the lever 105 is formed as a monolithic hollow block. In another embodiment, the lever 105 is formed by threadably connecting two portions, i.e., a first portion 115 and a second portion 120. More specifically, the first portion 115 has internal threads which are connected with external threads configured on the second portion 120. In an embodiment, the first portion 115 has larger cross-sectional area as compared to the second portion 120 of the lever 105. In an embodiment, the arrangement 100 comprises a support plate 125 configured at a free end 130 of the lever 105. At least one slot 135 is configured on the support plate 125. In an embodiment, the slot 135 has a rectangular shape. In yet another embodiment, a plurality of slots is configured on the support plate 125 along the longitudinal axis thereof. Each slot is configured at an angle with respect to the subsequent slot. In an embodiment, the slots are configured orthogonal to each other.
In another embodiment, the support plate 125 is formed integral with the lever 105.
The arrangement 100 further comprises a cable 140. The cable 140 is partially received in the passage 110. More specifically, a first end 145 of the cable 140 extends beyond the passage 110 and a second end 150 of the cable 140 is received within the passage 110. The first end of the cable 140 is coupled to a second system (not specifically shown in figures). An extension and retraction of the cable 140 operates the second system. In an embodiment, the second system is a creeper system of the tractor. The first end 145 of the cable 140 is connected to a creeper actuating lever 155. The extension and contraction of the cable 140 angularly displaces the creeper actuating lever 155, thereby operating the creeper system. In an embodiment, the first end 145 of the cable 140 is passed through a positional bracket 160. The positional bracket 160 is configured proximal to the creeper actuating lever 155, and is further configured to support the cable 140.
The arrangement 100 further comprises a pulling mechanism 165. The pulling mechanism 165 is coupled to the second end 150 of the cable 140 in the passage 110, and is configured to extend or retract the cable 140 through the passage 110 to operate the second system.
The pulling mechanism 165 comprises a rigid member 170, a biasing member 175, a locking pin 180, a knob 185, and a seat 190. The rigid member 170 is connected to the second end 150 of the cable 140, and extends beyond the free end 130 of the lever 105. More specifically, the rigid member 170 extends through the slot 135.
The biasing member 175 is securely disposed in the passage 110 such that the biasing member 175 circumscribes the rigid member 170. The seat 190 is connected to the rigid member 170 proximal to the connection between the rigid member 170 and the cable 140. More specifically, the biasing member 175 is securely disposed between the support plate 125 or the closed free end of the lever 105 and the seat 190. The support plate 125 and the seat 190 secure the biasing member 175 in the passage 110. In an embodiment, the biasing member 175 is a spring. Further, the seat 190 is configured to compress the biasing member 175 when the rigid member 170 is displaced away from the free end 130 of the lever 105.
The knob 185 is connected to the rigid member 170 for easy handling and facilitating linear displacement of the rigid member 170.
The locking pin 180 is configured on the rigid member 170. The locking pin 180 is configured to pass through the slot 135, which is configured on the support plate 125, when the rigid member 170 or the knob 185 is pulled away from the free end 130 of the lever 105.
The working of the arrangement 100 is now described in subsequent paragraphs with reference to the first system as the gearbox and the second system as the creeper system of the tractor.
To operate the gearbox, the lever 105 is displaced in the predetermined directions. The lever 105 acts as a gear shifting lever. With reference to the gearbox, the predetermined directions of the lever 105 refer to directions in which the lever 105 needs to be displaced in order to change the gears.
To operate the creeper system, the knob 185 is pulled away from the free end 130 of the lever 105. Due to pulling of the knob 185, the rigid member 170 is linearly displaced in an operative upward direction, thereby compressing the biasing member 175. The cable 140 gets extended and the creeper actuating lever 155 gets angularly displaced. The knob 185 is pulled outwardly to such an extent that the locking pin 180 protrudes out of the lever 105. To keep the creeper actuating lever 155 in actuated position, the knob 185 is rotated such that the locking pin 180 rests on an outer surface of the support plate 125 or the free end 130 of the lever 105 defining a first locking position of the rigid member 170 (as shown in figure 4). To bring the creeper actuating lever 155 to its initial position, the knob 185 is rotated such that the locking pin 180 can pass through the slot 135. The compressed biasing member 175 pushes the seat 190, and hence the rigid member 170 moves operatively downwards. This retracts the cable 140 to angularly displace the creeper actuating lever 155 back to its initial position.
Although the Figure 4 illustrates one locking position of the pulling mechanism 165, multiple such locking positions can be achieved by arranging multiple slots on the support plate 125. The number of locking positions is determined according to number of positions to which a lever of the second system needs to be displaced.
The working of the arrangement 100 is described in prior paragraphs with reference to the gearbox and the creeper system of a tractor. However, the arrangement 100 is not limited to operate the gearbox and the creeper system, and can also be used to operate any other two systems of a vehicle. In an embodiment, the arrangement 100 is used to operate a gearbox and a power take-off shaft of a tractor.
Conventionally, two separate levers were required to operate two systems, for example, a gearbox and a creeper system of a tractor. However, the arrangement 100 can alone operate two systems, for example, a gearbox and a creeper system. Thus, the arrangement 100 reduces number of levers in the driver cabin of a vehicle. Further, the arrangement 100 saves space and improves aesthetics of the driver cabin of a vehicle.
The arrangement, of the present disclosure, can be used in any vehicle. Particularly, the arrangement is useful in tractors as there comparatively more levers in tractors.
