Embodiment

Illustrate embodiment of the present utility model with reference to the accompanying drawings.

Fig. 1 shows the side view of tractor, and the tractor includes：Car body 1；It is arranged on the hood in the front of car body 2；Engine E in hood 2；Gearbox 3, includes speed change gear, from engine E's in the gearbox 3 Rotary power is transferred to the speed change gear from engine E；And front-wheel 4 and trailing wheel 5, revolved after being slowed down by speed change gear Rotatory force is transferred to front-wheel 4 and trailing wheel 5.Mud guard 5a is arranged to cover trailing wheel 5, so that the mud splashed by trailing wheel 5 Pilot set 7 will not be reached.

Engine E rear is arranged on for manipulating the steering wheel 6 of front-wheel 4,4, operator seat 7 is arranged in steering wheel Rear.In addition, security framework 7a is arranged in the rear of operator seat 7.

The vehicle frame 8 for extending to the front of car body 1 is configured to keep the engine E left and right sides.Vehicle frame 8 includes several each other Abreast it is arranged in the left plate 9L and right panel 9R of the left and right sides and connects left plate 9L and right panel 9R front cross Foreboard 9F, forms horizontal U-shaped when they see in plan view.

For the power from engine E to be included being located at it respectively from the power transmission shaft 11 of crankshaft pulley part onwards transmission The universal joint 11a of front and rear, and intermediate portion is divided into two halves and engaged by square spline, so that it can Extend in a longitudinal direction.

As a result, the diameter of power transmission shaft 11 is reduced.Moreover, when load is applied on body, power transmission shaft 11 is in longitudinal side It is flexible upwards, it is therefore prevented that power transmission shaft 11 is damaged.

Power transmission shaft 11 is covered to be surrounded and covers, so as to prevent its side's splined section by the influence of mud etc..

In addition, gear-box 12 is arranged on the front portion of car body, and built with being connected to power transmission shaft 11 and change its rotating speed Gear.The rotary power of power transmission shaft 11 is input into gear-box 12 and changes its speed, and drives preceding PTO (power output) axle 13, the PTO shaft 13 is prominent from the preceding surface of gear-box 12 to the front of car body.

Power transmission shaft 11 is arranged between the left plate 9L of vehicle frame 8 and right panel 9R by the otch 15 of axle housing bracket 14.

As described herein, axle housing bracket 14 is provided with otch 15, arranges power transmission shaft 11 by the otch 15, therefore, relatively In direction of traffic, the construction is compact.

Gear-box 12 be mounted and by be bolted to by vehicle frame 8 left plate 9L and right panel 9R and laterally connect left plate In the space that 9L and right panel 9R foreboard 9F is surrounded.Moreover, gear-box 12 can immediately follows be arranged on foreboard 9F rear, so that Reduce the angle of bend of power transmission shaft 11 as far as possible, i.e. so that power transmission shaft 11 is arranged in into straight line as far as possible relative to fore-and-aft direction On.As a result, PTO shaft 13 before being obtained by compact way, this allows to install work machine closer to the present apparatus Operation is carried out in front portion, therefore with good balance.

The rear portion of gear-box 12 is fixed to gear block 20, and gear block 20 is fixed to the left plate 9L and right panel of vehicle frame 8 9R。

In order to easily safeguard, gear-box 12 is arranged on the lower section of battery substrate 18 for installing battery 17.In addition, Battery substrate 18 has a flat bottom surface, and power transmission shaft 11 be disposed in below the flat bottom surface with closely this put down Smooth lower surface.The bottom of gear-box 12 is prominent below axle housing bracket 14, and preceding PTO shaft 13 is in the preceding table of the bottom of gear-box Protruded at face.

Preceding PTO shaft 13 is arranged on below foreboard 9F, and is protruded forwards.In addition, preceding PTO shaft 13 is provided with for covering The protective cover 16 of its left, right and top (protective cover left part 16a, protective cover right part 16b and protective cover top 16c), this is prevented Protecting cover is arranged on the preceding surface of gear-box 12 with PTO shaft 13 before protecting.

So, the contact with preceding PTO shaft 13 is prevented.In addition, PTO shaft 13 is influenceed by wind and rain before preventing.

Traction connector 19 is arranged on foreboard 9F, and is arranged on the top of preceding PTO shaft 13.Anterior work machine is easy On traction connector 19 and preceding PTO shaft 13.

Vehicle frame 8 is provided with stiffener 21 to receive the power on fore-and-aft direction at its side surface.

Therefore, the vibration of gear-box 12, power transmission shaft 11 and preceding PTO shaft 13 is reduced.

In addition, the exhaust outlet 23a of engine E blast pipe 23 is arranged in left plate 9L sides and under hood 2 Side.So, rainwater etc. is prevented to enter exhaust outlet 23a, and design is also appeared to more preferably.

Note, in the accompanying drawings, 22 be the radiator for cooling down engine.
