SUMMARY OF THE INVENTION An object of the present invention is to provide an industrial vehicle capable of reducing distortion on the vehicle drive means side.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, in the industrial vehicle according to claim 1 of the present invention, wheel devices are arranged in a plurality of left and right rows and a plurality of front and rear portions on the lower side of the vehicle body, and front and rear end portions of the vehicle body. At least one of them is provided with a driving section, and vehicle driving means is mounted on the front and rear intermediate portion of the vehicle body via a shock absorber , and the vehicle driving means is disposed on the frame body and the frame body. The frame unit is constituted by an engine unit, and the frame body is a rectangular flat frame-shaped base body, vertical casings erected from the four corners of the base body, and mounting brackets that are continuously provided outward from the upper ends of the vertical casings. And the engine unit is disposed on the base body, and the shock absorber includes a receiving bracket body provided vertically on the lower surface side of the vehicle body so as to face each mounting bracket body from below, Receive these A rubber plate arranged between the lower surface of the loaded bracket body and the upper surface of the bracket body by a connector performing a connection between the bracket body in a state where the rubber plate group is interposed, is composed of a rubber mount type It is characterized by being.
[0006]
Therefore, according to the first aspect of the present invention, for example, when the vehicle body bends when the object to be transported is loaded on a rough road, the rubber plate is elastically deformed according to the vehicle body deflection, thereby buffering the vehicle body deflection. Absorbing by the apparatus can reduce the distortion of the frame on the vehicle drive means side. Also, the rubber mount system can maintain the normal posture of the vehicle drive means when the vehicle body is not bent.
[0007]
The industrial vehicle according to claim 2 of the present invention, in the configuration of claim 1, wherein the above, the engine unit is obtained by the features that you have been provided through a mount rubber on the base body.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings as a state where it is adopted in a front and rear driving section type traveling carriage.
[0010]
A traveling carriage 1 which is an example of an industrial vehicle is provided with driving units 3 and 4 at both front and rear ends of the vehicle body 2, and covers the top of both driving units 3 and 4. A loading platform 5 is provided. On the lower side of the vehicle body 2 is provided a wheel device 10 that can turn around the longitudinal axis 6 with respect to the vehicle body 2. It is arranged at a place (a plurality of places before and after).
[0011]
The wheel device 10 has an upper disk part 11 supported and guided on the outer ring body 7 side provided on the vehicle body 2 side and rotatable around the longitudinal axis 6. On the side, an axle 12 is provided. The axle 12 includes an upper bracket 13 connected downward from the upper disk portion 11, a lower bracket 15 connected to the lower end of the upper bracket 13 via a lateral shaft 14, and between the brackets 13, 15. And a cylinder device for bending and stretching (not shown) provided in the.
[0012]
A wheel 17 is provided on the free end portion of the lower bracket 15 so as to be divided into left and right via an axle 16, and a wheel drive unit (not shown) linked to the axle 16 is provided on the free end portion of the lower bracket 15. Z.) is provided. An example of the wheel device 10 having the wheel drive unit is configured by the above 11 to 17 and the like. Further, turning drive means (not shown) for turning the wheel device 10 around the longitudinal axis 6 is provided.
[0013]
A pair of left and right (two) vehicle drive means 20 are disposed in the front and rear intermediate portion of the vehicle body 2, and these vehicle drive means 20 are mounted on the vehicle body 2 side via shock absorbers 30, respectively. The two vehicle driving means 20 are configured to handle the wheel device 10 group in two groups in the vehicle length direction.
[0014]
That is, each vehicle driving means 20 is configured by a frame body (bracket) 21 and an engine unit 26 disposed on the frame body 21. Here, the frame body 21 is a rectangular flat frame-shaped base body 22, a vertical rod body 23 erected from the four corners of the base body 22, and a mounting that is continuously provided outward from the upper end of the vertical rod body 23. The bracket body 24 is configured. The engine unit 26 includes an engine, a hydraulic pump, and the like, and is disposed on the base body 22 via a mount rubber 27 and the like.
[0015]
The shock absorber 30 includes a receiving bracket body 31 provided in a suspended manner on the lower surface side of the vehicle body 2 so as to face each mounting bracket body 24 from below, an upper surface of the receiving bracket body 31, and the mounting bracket body 24. A plurality of connectors (bolts and nuts) that connect the bracket plates 24 and 31 with the rubber plate 32 disposed in a state where a plurality of sheets are laminated between the lower surface and the rubber plate 32 group. Etc.) 33 etc., and is configured in a rubber mount system.
[0016]
The operation in the above embodiment will be described below.
The traveling cart 1 travels forward, for example, by driving into the driving unit 3, and travels backward by driving in the driving unit 4. Then, the axle 12 in the wheel device 10 is bent to move the loading platform 5 side to the lowered position, so that the traveling carriage 1 can travel below the object to be transported, and the loading platform 5 can be positioned below the object to be transported. . Next, the axle 12 is extended to raise the loading platform 5, so that the article to be conveyed can be lifted by the loading platform 5, so that the conveyance object can be conveyed by the traveling movement of the traveling carriage 1. The traveling carriage 1 can turn right or turn left by turning the wheel device 10.
[0017]
In such a traveling movement of the traveling carriage 1, for example, the vehicle body 2 bends when the object is loaded and travels on a rough road. In this case, the rubber plate 32 group according to the bending of the vehicle body 2. Will be elastically deformed, so that the distortion of the frame body 21 can be reduced, and there is no possibility of adversely affecting the engine unit 26 and the like.
[0018]
When the rubber mount system composed of the rubber plate 32 group is adopted as the shock absorber 30, the normal posture of the frame body 21 in the vehicle driving means 20 when the vehicle body 2 is not bent can be easily and stably performed. .
[0020]
In the above embodiment, although each operating units 3 and 4 in the front and rear end portions of the vehicle body 2 is provided, which, had shifted or the like form the operation portion is provided only one, the various forms of industrial It may be a vehicle.
[0021]
In the above-described embodiment, the loading platform 5 is provided above the vehicle body 2 so as to cover the upper portions of the driving units 3 and 4, and this is a portion of the loading platform 5 above the driving units 3 and 4. It may be a form in which is not located.
[0022]
In the above-described embodiment, the up-down bending-type wheel device 10 is shown, but this may be a turning-type wheel device that does not bend up-down. Moreover, the wheel apparatus etc. which do not turn may be sufficient.
[0023]
【The invention's effect】
According to the first aspect of the present invention described above, for example, when the vehicle body bends when the object to be transported is loaded on a rough road, the rubber plate is elastically deformed in accordance with the bending of the vehicle body. Can be absorbed by the shock absorber, thereby reducing the distortion of the frame on the vehicle drive means side and eliminating the risk of adverse effects on the engine unit and the like. The rubber mount system can easily and stably maintain the normal posture on the vehicle drive means side when the vehicle body is not bent.
