Description

[Detailed Description of the Invention] The present invention relates to a wire support structure for shifting gears of a vehicle, in which a wire that interlocks and connects a gear shift lever provided on a door and a gear shifting device on the vehicle body is passed through a cylindrical part of a support frame of a foot cover. This prevents the wire from being damaged and prevents the wire from getting in the way near the operator's feet.

In a vehicle such as a tractor, a door is provided between a foot cover on the side of the bonnet and a rear wheel fender behind the foot cover, which can be opened and closed using the front end as a fulcrum, and various speed change levers are incorporated into the door. There is a type in which this shift lever and a transmission on the vehicle body are interlocked and connected with a wire.
Conventionally, in this type of vehicle, the gear shifting wire is taken out from inside the front end of the door to the foot cover, bundled with a band, etc., and fixed along the foot cover, but since it is exposed, Not only was it unsightly, it was easily damaged, and each time the gear shift lever was operated, the wire would move and get in the way of the operator's footing, causing the operator to trip over it.

In view of these problems, the present invention aims to solve the conventional problems by using the support frame of the foot cover and inserting the wire through it.The features of this invention are as follows: A door that can be opened and closed using the front end as a fulcrum is provided between the foot cover on the side of the bonnet and the rear wheel fender behind the foot cover. In the interlockingly connected vehicle, the support frame of the foot cover has a lateral cylindrical part, and the wire is inserted through this cylindrical part.

The present invention will be described in detail below with reference to the illustrated embodiment. In Figs. 1 and 2, 1 is a tractor body, which comprises an engine 2, a clutch housing 3, a transmission case 4, etc., and includes front wheels 5L,
The tractor body 1 is provided with a pair of left and right rear wheels 5R and 6L, 6R. Reference numeral 7 denotes a bonnet which covers the engine 2 etc., and reference numeral 8 denotes a hydraulic device for raising and lowering the working equipment. Reference numerals 9L, 9R denote a pair of left and right rear wheel fenders, and a floor cover 10 is provided between the fenders 9L, 9R so as to cover the hydraulic device 8. Reference numerals 11L, 11R denote a pair of left and right steps which are provided on both sides of the center of the tractor body 1, and foot covers 12L, 12R are provided at the front ends of the steps 11L, 11R along both sides of the rear of the bonnet 7. Reference numeral 13 denotes a driver's seat which can be attached and detached in a reversed manner between a position above the hydraulic device 8 and a position at the upper rear end of the bonnet 9. Reference numeral 14 denotes a steering handle which is attached to the bonnet 7.
and a side position of the hydraulic device 8, and by mounting the driver's seat 13 and the handlebars 14 in the reversed manner,
It can be driven in both forward and backward positions.
A door 5 is disposed between the foot cover 12R and the fender 9R on the side opposite the normal boarding/disembarking side, and is pivotally attached to the foot cover 11R side about a vertical axis by a hinge 16 on the front end side so as to be able to be opened and closed freely, as will be described later.

Inside the transmission case 4, a traveling transmission 17, a shuttle transmission 18, a PTO transmission 19, etc. are incorporated, and each transmission 17,
Operating levers 20, 21, 22, 23, and 24 that are interlocked with shift forks 18 and 19 are provided on a transmission stand 25 mounted on the transmission case 4, respectively. As shown in FIGS. 3 to 5, the foot cover 12R is fixed to the tractor body 1 via a support frame 26 having a rigid frame structure. The support frame 26 includes a pair of horizontal cylindrical members 27 arranged above and below,
28, a vertical connecting member 29 that vertically connects the outer ends of the cylindrical members 27 and 28, and a pair of dogleg-shaped vertical members 30 and 31 fixed to the cylindrical member 27. The cylindrical member 27 is attached to the upper surface of the clutch housing 3 via a vertical member 32 and a mounting plate 33, and the cylindrical member 28 is attached to the side surface of the clutch housing 3 via a mounting plate 34. As will be described later, the cylindrical member 27 is also used for passing wires through it, and is constructed of a rectangular cylindrical body with a slightly larger size, and has a rear wall portion on the outer end side that is folded rearward as shown in FIG. A curved portion 35 is formed, and an elastic cover member 36 is fitted around the entire circumference of the outer end opening. On the upper surface side of the door 15, there are a travel gear shift lever 37 and a shuttle gear shift lever 3 that protrude upward.
8. PTO shift levers 39 are provided respectively.
The gear shift levers 37, 39 have H-shaped gear shift guide grooves 40,
41, the gear shift lever 38 has a linear gear shift guide groove 4.
2 in the front and rear directions. The travel gear lever 37 is connected to two wires 43, 4.
levers 20, 21 of the traveling transmission 17 via 4
, the shuttle shift lever 38 is connected to one wire 4.
5 to the lever 22 of the shuttle transmission 18
, the PTO gear shift lever 39 is connected to two wires 46,
47 to the lever 23 of the PTO transmission 19;
24, respectively. Each wire 43-4
7 are gathered on the front end side of the door 15, and
They are taken out to the cylindrical member 27 side through an opening 49 formed in the inner plate 48, and are inserted into the cylindrical member 27 all together. The wires 43 to 47 are guided from the inner end of the cylindrical member 27 to the levers 20 to 24 through both sides of the handle attachment portion 50. The wires 43 to 47 are bound and fixed inside the door 15 by a band 51, and
It is bound and fixed on the joint member 32 with a band 52. The door 15 is attached to a vertical connecting member 29 of a support frame 26 via a pair of upper and lower hinges 16.
An instrument panel 53 is mounted on the rear side of the upper surface of the door 15, and an electrical harness connected to the instrument panel 53 is also passed through the cylindrical member 27 together with the wires 43 to 47 and the like. In addition, the gearbox 2
5 is covered with a cover 56.

By inserting the wires 43 to 47 through the cylindrical member 27 that is a part of the support frame 26 as described above, the wires 43 to 47 can be inserted into the foot cover 12R.
- 47 are easy to handle, and the work is easier and the appearance is good compared to the conventional band or the like that is fastened along the foot cover 12R. Further, the wires 43 to 47 do not become an obstacle to the operator's feet, especially when operating the brake pedals 54L, 54R. Moreover, it also leads to a reduction in the number of parts, and it is possible to reduce manufacturing costs. The outer end of the cylindrical member 27 is connected to the wires 43 to 4 when the door 15 is opened or closed.
Since the wire 43 moves, it is preferable to form the wire 43 in an expanded shape so that the outside is wider.
~47 damage can be reduced.

In the above embodiment, the cylindrical member 27 was used, but as shown in FIG.
5, use this mold material 55 and foot cover 12R.
Wires 43 to 47 are attached to the cylindrical part formed between
You can also pass it through.

In the present invention, since the wire is inserted through the cylindrical part of the support frame of the foot cover, the appearance is better compared to the conventional one, and it does not get in the way, and damage to the wire can be prevented.
