Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a vehicle with a working device.

(Prior technology) As a vehicle with a lift device, the
There is a device shown in No. 116916, in which a two-axle, four-wheel vehicle with a counterweight at the rear is equipped with a lift device located in front of the vehicle.

(Problem to be solved by the invention) By the way, in order to work in a narrow space with a vehicle equipped with a lift device, it is necessary to shorten the wheelbase of the vehicle as much as possible and reduce the turning radius. No consideration has been given to this point, and improvements in this regard are desired.

An object of the present invention is to provide a vehicle with a working device that can solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized in that the engine 5 at the rear and the transmission case 8 disposed in front of the engine 5 and containing the transmission mechanism are connected to the vehicle body. The engine 5 and the transmission case 8 are equipped with a two-axle four-wheel vehicle 1 having a counterweight 4 at the rear of the vehicle body 3 and a working device 2 located in front of it. An intermediate case 7 which includes a transmission mechanism for transmitting power from the engine 5 to a transmission mechanism in the transmission case 8 is provided between the engine 5 and the transmission mechanism in the transmission case 8. A transmission case 8 is coupled to the lower front side of the counterweight 7, a rear axle 12 is arranged below the engine 5, and the front part of the counterweight 4 is connected to the engine 5 and the rear axle 1.
It was placed between 2.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 indicates a vehicle for traveling on rough terrain such as a tractor, and 2 indicates a lift device exemplified as a working device.

The vehicle body 3 of the vehicle 1 includes a counterweight 4, an engine 5, a clutch housing 6, an intermediate case 7,
It consists of a transmission case 8, etc.

The counterweight 4 is located at the rear of the vehicle 1 and consists of a vertical portion 9 and a horizontal portion 10 projecting forward from the bottom of the vertical portion 9. A rear axle 12 is supported at the center of the horizontal part 10 in the front-rear direction, and is located below the horizontal part 10 and has rear wheels 11 on the left and right sides.

On the horizontal part 10 are an engine 5 and a clutch 13.
A clutch housing 6 containing a clutch housing 6 is connected in the above order, and a rear axle 12 is disposed below the engine 5. 14 is a radiator located on the rear part of the horizontal part 10, and 15 is a cooling fan.

The intermediate case 7 is fixed to the front surface of the clutch housing 6 and the horizontal portion 10 in a downwardly projecting manner, and the engine 5 is connected to the upper rear side of the intermediate case 7 via the clutch housing 6. Also, inside the intermediate case 7, there are three interlocking gears 16,
A transmission mechanism consisting of 17 and 18 is arranged vertically,
The highest gear 16 is interlocked with the clutch 13.

The mission case 8 projects forward from the lower front surface of the intermediate case 7, and is constructed by first to third cases 19, 20, and 21 being successively arranged forward in the above order. The transmission mechanism in the transmission case 8 is interlocked with the lowest gear 18 in the intermediate case 7, and from both rear sides of the third case 21,
A front axle case 23 containing a front axle 22 projects from both sides, and the front axle 22 is interlocked with a front wheel 24 .

A seat 25 is arranged on the transmission case 8, and a handle device 26 for steering the rear wheels 11 is provided in front of the seat.

27 is a fuel tank, and 28 is a bonnet.
29 is a four-post guard frame, and its front pillar 3
0 is fixed to the front end of the third case 21, and the rear support column 31 is fixed to the horizontal part 10 and the like. Further, a pair of left and right frames 32 are disposed on both the left and right sides of the mission case 8 in the front-back direction.

The lift device 2 is disposed at the front of the vehicle 1, and is tiltably and detachably attached to a frame 32 and the like via a pair of left and right brackets 33 and tilt cylinders 34.

The lift device 2 includes a pair of left and right fixed masts 35.
, a pair of left and right movable masts 36 provided on each fixed mast 35 so as to be able to rise and fall freely, a lifting platform 37 provided on both movable masts 36 so as to be able to rise and fall freely, and a lifting cylinder that raises and lowers the movable mast 36 and the lifting platform 37. , a pair of left and right L-shaped forks 38, etc., which are detachably attached to the lifting table 37.

According to the embodiment configured as described above, the rear axle 12 can be disposed below the engine 5, so it can be used with a vehicle in which the engine is disposed in front of the rear axle as in Utility Model Application No. 61-116916. In comparison, the wheelbase of the vehicle 1 can be shortened, and therefore the turning radius can be reduced, making it easier to work in narrow spaces.

Also, since the wheelbase of the vehicle 1 has become shorter, the distance between the center of gravity of the vehicle 1 with the lift device 2 and the center of gravity of the counterweight 4, that is, the moment arm, is shorter than before, but the distance in front of the counterweight 4 is shorter than before. Since the weight of the counterweight 4 is increased by disposing the counterweight between the engine 5 and the rear axle 12, the weight balance of the vehicle 1 with the lift device 2 can be made good. In addition, Counterweight 4
Since the weight of the counterweight 4 is increased by disposing the front part between the engine 5 and the rear axle 12, the overall length of the vehicle 1 does not become long and can be made compact.

Note that various types of work devices other than the lift device may be used as the work device.

(Effects of the invention) As described in detail above, according to the invention, a large space can be formed below the engine, which allows the rear axle and the front part of the counterweight to be placed below the engine. By locating the rear axle below the vehicle, the wheelbase of the vehicle is shortened and the turning radius is reduced, making it easier to work in tight spaces. Furthermore, by placing the front part of the counterweight between the engine and the rear axle, it is possible to increase the weight of the counterweight without increasing the overall length of the vehicle.
It is possible to eliminate poor weight balance caused by the shortening of the distance (moment arm) between the center of gravity of the vehicle and the center of gravity of the counterweight due to the shortening of the wheelbase. The present invention has the above advantages and is of great practical benefit.
