Description

field of invention

The invention relates to the suspension designed for narrow cab tractors used in tillage, fertilization, spraying, seed sowing, crop mowing and similar processes in fields, gardens, vineyards and city parks.

In particular, the invention relates to a narrow suspension with weight and height adjustment that offers a low SIP dimension (seat reference point) with a larger stroke (up and down movement) spring movement thanks to the use of a spring and shock absorber link plate moving part connected to the movable construction is connected.

Current state of the art

Suspension is the system of tires, tire air, spring, shock absorber and linkage system that connects a vehicle to its wheels and allows relative movement between the two. Tractors do not have a suspension system (especially those with non-suspended cabs) and their vibrations are high compared to other road vehicles. Therefore, the negative effects of vibration are more common among tractor drivers. Agricultural tractors are used for soil preparation before sowing, for planting, fertilizing, watering, tending and spraying, for harvest and post-harvest mechanization, for transport with trailers and for excavation work with various additional devices. Since the tractor is used in all farm mechanization operations, the drivers perform most of the farm work on the tractor.

Although vibration isolation studies in agricultural and forestry tractors have made significant advances with developing technology, few advances in suspension systems have occurred today in contrast to other motor vehicles for technical and economic reasons. Suspension measures are found in cabs and seats in direct proportion to the cost of tractors. Active suspension seats are also used with dampening plastic wedges or metal springs placed between the cab and the tractor body and chassis. As tractors become larger, wheel diameters are also increased and thus a benefit in dampening vibration is provided. As tractor mass increases, the cost of anti-vibration measures decreases.

Today, tractors working in field conditions use a suspension system under the cab to dampen the vibrations caused by poor road conditions and increase driver comfort. Especially with the under cab suspensions of tractors with narrow cabs, the suspension has less lifting movements and the SIP point (seat reference point) is high. Although there is no separate study for narrow cab tractors, various studies have been conducted to address the disadvantages of suspension systems used in construction machinery and tractors.

One of these studies is the invention, which is the subject of the patent application identified by number TR 2013/07031 entitled "Seat support structure in construction machinery". The invention relates to the seat support structure, consisting of at least one leaf spring in connection with the fastening element, used in construction machines such as tractors and forklifts with a narrow base, which prevents bending and drooping of the seat parts of the wall-mounted seats, which fastening elements and springs comprise, and which allows the seat to work with appropriate vibration levels.

Another study is the invention, which is the subject of the utility model application numbered TR 2009/06442 marked and titled "Air suspension driver's seat". The invention relates to tractor seats with a support chassis, an upper chassis connected to the chassis, a backrest sheet and a seat sheet and relates to an airbag into which air is pressed by means of a compressor, which provides air support and offers seating comfort in order to automatically adjust the seats depending on the driver's weight and relates to a suspension kit with a valve that triggers the compressor, which begins to inflate the airbag with the energy it receives from the vehicle's battery.

Consequently, there is a need for a narrow suspension which eliminates the disadvantages of the existing technology, and the inadequacy of the existing solutions has required an improvement in the technical field concerned.

Brief description of the invention

The present invention relates to the suspension developed for narrow cab tractors used in tillage, fertilization, spraying, sowing, crop mowing and similar operations in fields, gardens, vineyards and city parks be, with the above requirements, eliminates all the disadvantages and brings some additional advantages.

Starting from the state of the art, the aim of the invention is to reduce the outer width dimension of the developed suspension and to provide both a low SIP dimension and a flexible spring movement in the suspension with these narrow dimensions.

The aim of the invention is to provide flexible spring movement thanks to the spring used in the suspension and the moving part of the shock absorber connection plate.

Another object of the invention is to ensure that the scissor moves independently of the damping springs, thanks to the fact that the shock absorber is connected to the movable assembly of the spring and shock absorber connection plate between the base assembly and the upper body assembly.

Another aim of the invention is to provide more strokes (up and down movement) compared to existing applications thanks to the design of the suspension.

Structural features and characteristics of the invention and all its advantages will be better understood from the following figures and the detailed description with reference to these figures; therefore, the evaluation of the invention should be made by considering these figures and detailed descriptions

In the 1 Suspension shown (100) provides a measure of a low SIP point (A) (seat reference point). Thanks to the use of the spring and shock absorber link plate moving assembly (105) connected to the moving assembly inside, it has a spring action that makes more strokes (up and down movements). In addition, a weight and height adjustment can be made to the aforementioned suspension (100).

In the 2 The suspension (100) shown basically comprises: shock absorbers (104) for absorbing the incoming impulses; movable assembly of the spring and shock absorber connection plate (105) which supports the damping spring (114) and the shock absorber (104), forming the mechanism that moves between the main body and the base sheet (1361); and damper springs (114) absorbing tension from the weight adjustment mechanism.

In the upper part of the in 3 The suspension (100) shown is the upper body assembly (101) which supports the seat top and in the lower part the base assembly (136) which provides the vehicle connection by supporting the suspension parts (100) and the seat thereon.

By reducing the outside width dimension of the suspension (100) as in 4 shown, both the dimension of the lower SIP point (A) and the flexible spring movement are realized. In the 5 The suspension (100) shown comprises a safety sheet (137) providing the connection of the seat belt webbing (120) which prevents the suspension (100) from breaking due to tensile force; the weight adjustment spring transmission shaft (106) providing the connection of the damping springs (114) to the movable assembly of the spring and shock absorber connection plate (105); the shock absorber mounting pin (110) which attaches the shock absorber (104) to the moving assembly of the spring and shock absorber link plate (105); a scissors shaft (116) providing connection of the inner scissors unit (115) to the forearm base assembly.

The outer spring structure (123) comprises as a main part; the outer scissor plate (1231); the inner scissor and outer scissor connecting sleeve (1232) connecting the inner scissor plate (151) and the outer scissor plate (1231); the scissor shaft (116) connecting the right and left parts of the outer spring assembly (123); and the scissor reinforcement plate (1234) which increases strength.

In the 10 The weight adjustment bracket (126) shown transmits the weight adjustment to the dampening springs (114). The weight adjustment bracket (126) includes; a weight adjustment mounting plate (1261) providing the connection between the weight adjustment screw (131) and the scissors; and the weight adjustment nut (1262) centering the weight adjustment screw (131). The weight adjustment screw (131) which transmits movement from the weight adjustment arm to the springs comprises; the weight adjustment member (1311) that enables the weight adjustment, and the weight adjustment shaft (1312) that transmits the force coming from the weight adjustment member (1311) to the scissors.

In the 11 base assembly (136) shown; the base plate (1361) as the main component; elevator guide plate (1362) leading to elevator shaft; the base U-plate (1363) moving on the rollers acting on the scissor mount; scissor bushing (1364) providing connection of the inner scissor assembly (115) to the base assembly (136); elevator guide bushing (1365) for centering the elevator shaft; the base plate nut (1366) providing the connection; friction plate (1367) moving on the movable assembly of the spring and damper link plate (105); and the base screw (1368) providing the connections.

In the case of the suspension (100) according to the invention, the inner scissor unit (115) and the outer spring structure (123) are assembled first. Right and left inner scissor plate (1151), inner scissor roller bearing (1152), inner scissor tube (1153), scissor reinforcement plate (1154), weldment of the scissor tube mounting plate (1155) and the inner scissor intermediate support plate (1156) and the inner scissor assembly (115) . In order to reduce the width of the suspension (100), the inner scissor tube (1153) and the inner scissor intermediate support plate (1156), which are the lower parts constituting the inner scissor unit (115), are designed in shorter dimensions. The scissor tube fixing plate (1155) is fixed between the inner scissor tube (1153). In order to narrow the suspension (100), both the outer scissor shaft (1233) located on the outer scissor (123) and the inner scissor tube (1153) have been shortened. The spring (100) provides up and down springing movement by assembling the inner scissor unit (115) and outer spring assembly (123), inner scissor plate (1151) and outer scissor plate (1231) parallel to each other. When the scissor assembly is completed, the outer scissor link plate (1015) is welded to the upper body assembly (101) and the spring and shock absorber link plate moveable assembly (105) is assembled to the shock absorber mount link plate (1016). The Dampening Springs (114) are installed using the Weight Adjustment Bracket (126). One end of the dampening springs is connected to the weight adjustment bracket (126) and the other end is connected to the weight adjustment spring retention plastic (112) in the moving assembly of the spring and shock absorber link plate (105). The scissors are attached to the upper body assembly (101) and the base assembly (136). The inner scissor unit (115) moves in the small slider (1013) parts located in the upper body assembly (101) by means of scissor rollers (124); the outer scissor unit moves between the base U-plates (1363) located in the base assembly (136) by means of the scissor rollers (124). In order to reduce the width of the suspension (100), the upper body panel (1011) and the base plate (1361) of the inner scissor unit (115), the outer spring assembly (123) are designed in narrower dimensions. In order to provide a low SIP point (A) and thus provide a flexible spring action of the narrowly designed suspension (100), the moving assembly of the spring and shock absorber connection plate (105) is used.

The general principle of operation for the suspension (100) is as follows; in the direction of movement of the inner scissor unit (115) and the outer spring assembly (123) arranged in the suspension (100), the shock absorber (104) moves, which is connected to the movable assembly of the spring and shock absorber connecting plate (105), one end with the spring and the other end with the base assembly (136), along with the bearings (109) on the welded friction plate (1367). With this movement, the spring and shock absorber link plate assembly (105) moves in the bosses on the shock absorber mount link plate (1016) which is welded to the upper body assembly (101) by means of the spring weight adjustment transmission shaft (106). The damping springs (114) ensure in connection with the moving assembly Spring and shock absorber link plate (105) for tension. While the dampening springs (114) move with the scissors in current applications, in the suspension (100) according to the invention they are designed to move independently of the inner scissors unit (115) and the outer spring assembly (123). The seat belt webbing (120), on the other hand, provides a connection between the upper body assembly (101) and the base assembly (136) and prevents breakage of the suspension that can occur due to traction.

Designed in a very small footprint, the suspension (100) offers increased travel, flexible spring action, and a reduced SIP point (A) dimension through the connection of the shock absorber (104) with the inner scissor assembly (115) and the moving assembly of the spring- and shock absorber link plate (105) and the damping springs (114) are designed to move independently of the scissors compared to current applications. The rider can use the weight adjustment screw (131) to adjust the suspension (100) for their own weight and use the height adjustment screw assembly (132) to adjust the suspension (100) to the desired stroke size.

A sliding connection is made with the upper body panel (1011) positioned on either side of the upper body assembly (101) of the suspension (100). With the projections having a shape that extends outwards to these edge portions on the upper body panel (1011), the sliders are attached to stay down. Thanks to this shape, the vertical SIP point (A) is brought to the lowest level. The central part of the upper body panel (1011) has been given a height difference mold to maximize the lift (height) of the seat.

A friction plate (1367) has been added to the base plate (1361) in the base assembly (136). The spring and shock absorber link plate moving assembly (105) that allows the suspension (100) to move up and down does not provide ergonomic spring movement by moving on the base plate (1361) on the flat ground. Thanks to the friction plate (1367) welded to the base plate (1361), the suspension (100) is more ergonomic, flexible and has a higher stroke.

The narrow springs currently used achieve a maximum stroke of 60 mm. In the suspension (100) which is the subject of the invention, the moving assembly of the spring and shock absorber connection plate (105) is mounted between the base plate (1361) and the upper body panel (1011) and at the same time the spring travel (100) is increased 90mm by connecting the dampening springs (114) to the moving spring and shock link plate assembly (105) instead of the inner scissor assembly (115) and outer spring assembly (123) as in the existing suspensions.
