Description

[Detailed description of the invention] name of invention Detailed Description of the Invention: Loading Platform for Vehicles, Particularly Automotive Loading Apparatus for Vehicles This invention relates to a loading platform for a vehicle, and particularly to a loading platform for a vehicle in the longitudinal direction of the platform by means of an actuating cylinder device. and load/unload the vehicle with its rear end against the chassis frame. The present invention relates to an automobile loading device for use in vehicles. The surface of the stand is A flat recess that crosses the frame and continues in the longitudinal direction of the table, or connects the two ends of the table. It has a continuous downward curve or downward bulge below the virtual straight line.

In this type of vehicle (EP-0011250), a hatch-up loading platform The support roller is lifted from an inclined position by a tensioning device acting on the suspension of the rear axle. through the rear of the vehicle to a hatch position at the rear of the vehicle. Drive the vehicle and place it on the platform In order to obtain the most favorable angle when moving, also the frame of the loading equipment chassis to prevent damage from impact with surfaces. Shorten and chamfer the chassis and/or suspend the chassis for loading the platform. It has been suggested that it is possible to draw people into a situation. This is because the vehicle runs on this type of platform. This means that the angle is in the range of 12'' to 15''.

In modern vehicles that drive on roads, road clearance is more important than traditional aprons. More and more vehicles are being fitted with front and rear spoilers to reduce the space. child Vehicles equipped with such a spoiler must have a folding or sliding base extension. The above-mentioned stacking method can only be achieved if the angle at which it moves on its own and rises to the platform is made smaller. You can move up onto the platform by yourself. However, these extended platforms requires more space for loading, so the vehicles being transported are often parked closely together. If the The added base increases the arm length of the pivot and reduces the load placed on the chassis by the vehicle. In order to increase this, it is also necessary to strengthen the chassis.

The loading platform structure has a downward bulge (US-PS4) at its rear end or its entire length. , 842, 470), but this design A concave groove extends the entire length of the stand, but instead of this groove, a wedge-shaped concave part is used. This eliminates the above-mentioned drawbacks, since the ridges are added to the otherwise straight trailing edge. It has not yet been reached.

It is therefore an object of the invention to provide a loading platform of the type described above which does not suffer from the disadvantages mentioned above. i.e. have relatively high front and rear spoilers, and therefore reduce road clearance. To provide a structure that allows vehicles with small balances to be loaded without damage. There is a particular thing.

This purpose is achieved by providing a downward curve in the rear part of the platform for loading and unloading of vehicles. When rolling, the rear end of the vehicle does not touch the road surface and the front end of the vehicle The ground contact surface of the wheels is below the virtual straight line G when the rear wheels of the vehicle are located at the rear end of the platform. , the vehicle's wheelbase is shorter than the length of the downward curve, and the front spoiler This is achieved by creating a structure in which the rubber does not come into contact with the surface of the table.

The basic idea of the invention is therefore to form a flat platform as was previously done. It is not necessary to form a groove that runs the entire length of the platform, but instead runs downwards in the rear part of the platform. Forming a concave curve, the front wheels of the vehicle are aligned with the rear end of the vehicle, with the platform lowered. In particular, do not let the spoiler collide with the road surface, and do not let the front end, especially the spoiler, touch the surface of the platform. The goal is to configure the structure so that it passes through this curve without causing any problems. Usually on the back part of the stand. Form a downward concave curve that is lower than the surface of the flat platform being used; By making the downward concave curve longer than the wheelbase of the loading vehicle. Therefore, for a particular vehicle, the most extreme position in vehicle loading and unloading, i.e. If the wheels are still in contact with the road surface and close to the edge of the platform, the position of the front wheel is is considerably lower than a flat platform or a platform with grooves along the entire length of the loading surface. It is also possible to allow positions such as The slight amount provided by this technique Even on vehicles with a rear overhang depending on the angle, the rear end will not scrape the road surface. is avoided.

Characteristic elements of the invention are set out in the dependent claims.

The edge that touches the road surface when the platform is in the lowered position (the edge where loading begins) formed with a step extending at a predetermined angle, starting from The value of having the above-mentioned rear end on the platform leading to the dome part is this. This is evidenced by the characteristics of This structure is achieved by further shortening the length of the table. A vehicle with a low front spoiler that gives the advantage of Provides the added convenience of clearing the platform surface prior to raising. This step is , providing the same convenience as forming a folding or pull-out extension to the base. .

The invention will be explained in detail below using design examples shown in the drawings.

The drawing shows: Figure 1 shows a well-known vehicle with a loading platform in a state where a vehicle is being loaded. Figure 2, a side view showing the outline of both loading devices, shows the loading of a car. A side view corresponding to FIG. 1 and FIG. 3 when using the loading platform of the present invention are shown in FIG. , a schematic representation of a recessed loading platform according to the invention with a step at the rear end of the platform longitudinal section, FIG. 4 is a longitudinal sectional view similar to FIG. 3 without steps, and Figure 5 shows a front spoiler with a road clearance of 125 mm. Used for loading vehicles where the distance between the front spoiler and the front axle is 760 mm. Figure 4 shows a concave curve similar to Figure 3, showing the actual dimensions of the case;

The automobile loading device shown in FIG. 3 is provided on a chassis 8.

The chassis is provided with an actuating cylinder device 4, which cylinder is used for loading and unloading. When loading and unloading vehicles onto and from the platform 3, move the loading platform 3 forward and backward. At the same time, the loading platform 3 is moved to the rear end centering on the axis that crosses the chassis frame. tilt towards. For this purpose, the loading platform 3 is normally placed at a distance of 12" to the road surface. The loading angle ranges from 15° to 15°. Loading platforms with this configuration have been known for a long time. ing.

Vehicles, especially large front spoilers 5 and/or rear spoilers 6 or front and Use the spoiler, underside of the car body, exhaust pipe, etc. of a car with a rear overhang as a base. In order to be able to load onto the platform without collision, the A shallow recess 9 is formed along the longitudinal direction of the platform on the rear side facing the loading axis. has been done.

This depression has a downward curve or a downward bulging shape, and its length As shown in Figure 4, L is equal to or greater than the average wheelbase of a normal car, which is 2. There is. At the rear end or rising end 13 of the downward curve, as shown in FIG. M steps 18 may be provided. This step is a multiplication at the starting point 11. It continues to the raised end and continues to the dome part 12 at the front end.

Connect the front and rear ends of the downward curve or downward bulge 10 extending along the platform. Distance A1, A! to virtual straight line G! , A8 and A4 are the fluorocarbons of the car to be loaded. Ground clearance or road clearance determined by front and rear spoiler 5.6 has been done. Therefore, the straight line G is located above the downward curve or depression 9.

The rear step 18 is performed when the front wheels 14 of the automobile 2 are still on the road surface 16. This is necessary to ensure that the spoiler does not get in the way of passing. The rear end of the stand, i.e. The starting point 11, which is located in the immediate vicinity of the rising edge 13, has a sharp This is a necessary design element to eliminate edges. This starting point 11 is where the car is When riding on the platform, the front wheels and spoiler 5 are suddenly raised. The front wheel is stuck. When passing through the curve 18, the behavior of the spoiler facing the downward curve 10 is almost non-existent. can be seen.

The downward curve 10 is located at the rear part of the platform 7 and is larger than half of the total length of the platform. occupies . This downward curve 10 is used when the vehicle 2 is loaded or unloaded. The rear end 6 does not touch the road surface 16 and the front wheels 14 When the rear wheel 17 is located at the rear end 13 of the platform, the ground contact surface of Its shape is determined so that it is located. The vehicle's wheelbase has a long downward curve. The front spoiler 5 is shorter than the front spoiler 5, and is not obstructed by the surface of the base.

The downward curve of the platform 7 is made using three groups of spoilers, along with steps. set. These tests were conducted under the following conditions.

Group a) Spoiler height 125mm, distance to front axle 760m up to m. This is common for standard models offered by car manufacturers.

Group b) The height of the spoiler is 120 mm and the distance to the front axle is 95 mm. Up to +m. This applies to sports cars, certain standard models, and special order models. Common.

Group C) The height of the spoiler is 120mm and the distance to the front axle is 1.10 Up to 0mm. This is used for products made to order by automotive stylists. .

The step 18 of the riding edge 13 depends on the front part of the spoiler and is similar to C and C in FIG. The rising dimension of the platform surface in the section indicated by D and D, that is, the clearance from the road surface, is approximately It was found that 50 mm to 110 mm is characteristic. At the end of step 18 At a height of 110 mm at Touch the spoiler to E (Fig. 3), which is approximately 750 mm above the road surface 16 at the front end of the curve. I was able to pass through a downward curve without losing weight. If there is a downward curve on the road If the step is not provided on the platform 7, The position of the riding end 13 needs to be moved further to the rear, which causes design problems and This is not preferable in terms of the above-mentioned required space.

A downward-facing car that damages the long front spoiler 5 and requires a longer base length. The bulb 10 can also be used as a rear spoiler 6, a lower exhaust pipe or an automobile doper device (tower). bar assembly) also has a significant meaning.

According to the test, if you select the shape of the base suitable for each front spoiler 5, the virtual If the downward curve 10, which is always located below the straight line G, is not large enough, ( In other words, if the clearance A is not sufficient), the rear wheels 17 of the vehicle are close to the road surface 16. After the car scrapes the road surface in the loading area before it reaches the top end 13. I end up lifting the part. The corresponding behavior is when the wheelbase is 2400m+n to 2 Occurred with respect to various automobiles at 700 am. Therefore, the downward curve 10 corresponds to the rear wheel 17, before the front wheel 14 reaches E (Fig. 3) (i.e., the front wheel is in a downward curve) 10 and is therefore located below the straight line G), the rising edge of the platform It must be shaped so that it rides on the surface.

However, if the loading slope of the normal loading platform is As mentioned above, place the downward curve on the edge of the spoiler and the top of the car. The shape will be determined by the geometry of the front wheels that remain on the road and the rear wheels that remain on the road surface. Therefore, it means that it can be done quickly. The variables that have these effects are The product of the vehicles in group a) above on the downward curve shown in Figure 5, taking into account the The curve of the loading platform in the loading area was calculated. As shown in Figure 5, this Starting from point F on the curve of An inclined straight line K is drawn that slopes upward. From this point, the loading platform in front is , was able to rise at an angle of 15 degrees, but this was at the front point E1, that is, the edge of the chassis. The structural length of the vehicle from section 19 (Figure 4) to point F must be approximately 4,000 mm. means that it must be done.

The proposal of the present invention is to shorten the position of the starting point F of the slope to the position H, and to reduce the structural length by 3. , 100mm.

Further, as shown in FIGS. 3 and 5, a step 18 provided behind the starting point 11 The structural length of the rear part is reduced to 2.750 mm.

The distance M from the starting point, which is determined by the distance between the car spoiler and the front axle, is In the case of vehicles in group a), it is 650 mm. This is done through extrusion during vehicle manufacturing. The length can be reduced or the rear structural end can be shortened by 1°250mm. This dramatically reduces manufacturing costs.

For vehicles of group b), the same downward curve is used to move the loading platform. but the angle is reduced from 15'' to 12''. however , Since the spoiler is provided protruding 190!1+11 forward, this part Correspondingly, the length of the step increases, and therefore the length of the downward curve increases.

In the case of vehicles of group C), which at least at present only include vehicles that are made to order, the above The elevation angle is reduced to 9''. At a certain height of E, the position of point H is extended and The step length is increased from 650mm to 99011111.

As shown in FIG. 4, the position of the downward curve 10 on the surface of the platform is such that the platform 7 When the loading device 1 is tilted from the chassis end 19, the rear side of the chassis end 19 It is desirable to start from
