部品点数も多くなると云う欠点を有している。 Conventionally, in a tractor in which driving force is transmitted to the front wheels, a gear case for extracting driving force from the front wheels is fixed to the lower surface of a transmission case located at the rear of the body of the tractor. Also, one end of the brake pedal, which is interlocked and connected to the brake device, is connected to a pedal shaft having a left-right axis, and this pedal shaft is rotated around the axis by a support member on the bottom or side surface of the transmission case. freely supported. For this reason, it is necessary to process the mounting parts in at least two places on the transmission case to fix the front wheel drive force extraction gear case and the support member, which increases the number of processing and assembly steps.
It has the disadvantage that the number of parts increases.

構成したものである。 This idea eliminates the need for parts to attach the pedal shaft by supporting the pedal shaft to which the brake pedal is connected with the front wheel drive force extraction gear case itself, which is fixed to the underside of the transmission case. Therefore, the structure is such that it is possible to reduce the number of parts, the number of processing steps, and the number of assembly steps.

ている。 An embodiment of this invention will be described based on the drawings. A gear case 3 for extracting front wheel drive power is located on the underside of the transmission case 2 of the body 1 of a four-wheel drive tractor.
is permanently installed. This front wheel drive force extraction gear case 3 is provided with a drive force extraction shaft 4 that protrudes forward, and an input shaft that protrudes rearward from a gear case (not shown) provided on the front wheel 5 side. (not shown), this input shaft and the driving force extraction shaft 4 are connected by a drive shaft 6 and a joint 7, and these drive shaft 6, joint 7, front wheel drive shaft 4, and input shaft are protected. It is covered by a pipe 8. A support portion 9 is integrally formed with the front wheel drive force extraction gear case 3, and a pedal shaft 10 having a left-right axis is rotatably supported on the support portion 9. A brake pedal 11 and a lever 12 are fixed to this pedal shaft 10. A support shaft 15 having a horizontal axis is supported around the axis on a support body 14 on the side of the brake device 13 provided on the side of the transmission case 2, and a lever 16 is mounted on this support shaft 15. and a brake arm 17 are fixed, and this lever 16 and the lever 12 are connected by a brake rod 18. The brake devices 13 are independently provided on both the right and left sides of the transmission case 2, and the brake pedals 11 connected to these brake devices 13 are also independently arranged in pairs on the left and right, and the pedal shaft 10 There are also two independent pairs on the left and right. Furthermore, a parking brake lever 20 is provided on the left side of the driver's seat 19 for simultaneously operating the left and right brake devices 13 when parking the aircraft 1.

The support part 9 that supports the pedal shaft 10 is integrally formed with the front wheel drive force extraction gear case 3. Therefore, there is no need to provide a separate support member to support the pedal shaft 10, and the number of parts can be reduced. .
Then, it is only necessary to attach the front wheel drive force extraction gear case 3 to the transmission case 2, which reduces the number of assembly steps and the number of processing steps required for attachment to the transmission case 2.

果を有するものである。 As mentioned above, this idea uses the front wheel drive force extraction gear case as a support member for the pedal shaft, eliminating the need to attach a support member for mounting the pedal shaft to the transmission case, thereby reducing the number of parts. In addition, the pedal shaft can also be attached to the transmission case by simply attaching the gear case for extracting the front wheel drive force, which has the effect of reducing assembly and processing steps. It is something.
