Abstract

PURPOSE:To enable a vehicle to easily come off a bad road, by attaching a hydraulic pressure-operated jack to the lower section of the vehicle so that the jack is movable, selectively in the vertical and longitudinal directions. CONSTITUTION:A hydraulic pump 21 is coupled to an engine 20. Further, valves 22, 23 are disposed, respectively in hydraulic pipe lines connecting between the pump 20 and cylinders 2, 10. When the valve 22 is opened, the cylinder 2 is operated to raise a vehicle. When the valve 23 is opened, the cylinder 10 is operated to roll the bottom surface 4 of a grounding section on a ground surface so that the vehicle moves. The vertical movement of the vehicle body is made by driving the cylinder 2 in a jack 1 while the vehicle may be easily come off a bad road, etc. by driving the cylinders 2, 10 in combination. The vertical and horizontal movements of the jack can be made not only by means of hydraulic pressure but also by other means.

Description

[Detailed Description of the Invention] <Object of the Invention> The present invention is intended to enable the vehicle body to be easily and safely raised and lowered in order to frequently and easily change tires and attach/detach chains in snowy areas in winter, and to prevent the vehicle from becoming muddy. This invention relates to a vehicle equipped with a device for easily escaping the vehicle from rough roads such as sludge, gravel roads, snow-covered roads, etc. when it is difficult to escape by normal driving operation.

<Conventional technology> When driving a vehicle in a snowy area in winter, depending on the road conditions, it is often necessary to put on and take off the chain, but in many cases, it takes time to put on and take off the chain. .

For safe and easy attachment/detachment, it is desirable to lift the υ vehicle body using jacks. Normally, this is done using a jack that is an accessory installed on the vehicle, but it requires a lot of effort and time.

Therefore, it is desirable to have a vehicle equipped with a device that allows the vehicle body to be raised and lowered with simple operations.

Additionally, if a vehicle enters a muddy road surface, a road surface covered with thick gravel, or a snow-covered road surface where the snow has not been completely removed in winter snowfall areas, the vehicle may often suffer from slips or other accidents. It is very difficult to escape from these bad roads.

When found in these various situations, most people try to escape by placing something under the wheels to increase friction, such as stones, wood, chains, cloth, etc. Particularly on snow-covered roads, methods such as pushing the vehicle across the rough road with the help of many people are used.

However, in order to place something that increases friction under the wheels, it is necessary to use jacks to lift the car body, and it is complicated to operate the jacks up and down, and it takes a lot of effort and time to escape.

Once you get stuck on a rough road, it is not easy to get out, and this type of trouble is especially common in areas with heavy snowfall, and there is a desire to develop a device that can easily get you out of a rough road.

Means for Solving Problems> The present invention solves the above-mentioned needs and relates to a vehicle in which a jack is attached to the lower part of the vehicle body so that it can be selectively moved up and down the vehicle body and in the direction of the cocoon layer.

The jack is equipped with a cylinder operated by fluid pressure,
It is desirable to move the vehicle up and down or in the forward direction by operating the cylinder.

<Embodiment> Various types of jacks can be used to move a vehicle using fluid pressure, and a preferred example invented by the present inventor is shown in FIG.

In the figure, / indicates a jack, which is composed of a cylinder part ko and a fan-shaped grounding part 3. The bottom part of the fan-shaped grounding part 3 is a curved surface with both sides, t, and left side being arcuate.

On the other hand, 6 is a support member fixed to the bottom of the vehicle, which rotatably supports the shaft fixed via the cylinder part of the jack and the flage shift.

Since it is configured as above, when lifting the car body,
Alternatively, when lowering the vehicle, that is, when moving the vehicle up and down, the cylinder portion may be operated. Also, when moving the vehicle body in the front direction, it is sufficient to move the jack in the front direction, but in the figure, apart from the cylinder part of the jack, there is a connecting tool 9 attached to the shaft so that the shaft can be rotated. A cylinder IO is provided which is connected to the vehicle body via a member /2 and is attached to the vehicle body via a member /2, and by driving this piston // the purpose can be achieved. That is, as the piston /l moves, the shaft g rotates, the fan-shaped ground contact portion 3 of the jack rolls on the ground surface, and the vehicle body fixed to the support member B moves. Note that the maximum distance of movement is the length of the arc of the bottom part.

It is preferable that the cylinder operates a hydraulic pump depending on the rotation of an engine or electric motor mounted on the vehicle. Moreover, not only hydraulic pressure but also fluid pressure such as air pressure can be used.

Next, the present invention will be explained in detail using a car as an example with reference to FIGS. 2 and 5.

In FIG. 2, 10 is a hydraulic pump connected to the engine 1.2/h. Further, 22.2.3 is a valve provided in a hydraulic pipe connecting the hydraulic bonder and each cylinder 2210. When the valve is opened, the cylinder operates and the vehicle rises. When the valve 3 is opened, the cylinder 10 is actuated, the bottom surface of the ground contact portion rolls on the ground contact surface, and the vehicle moves.

The vehicle body can be moved up and down by the drive of the jack cylinder, and movement of the vehicle body and escape from rough roads can be easily accomplished by combining this with the drive of the cylinder io.

The device shown in FIG. 1 would normally be provided adjacent to each wheel of the vehicle.

Note that the vertical and horizontal movement of the jack is not necessarily performed by fluid pressure, but may be performed by other means.

<Effects of the Present Invention> Moving the vehicle in the vertical and horizontal directions, which conventionally required much effort, can now be performed extremely easily.
