[0001]
BACKGROUND OF THE INVENTION
The invention of the present application attaches a platform that can be tilted backward to the rear of the cab of the vehicle, attaches a stepping plate that can rotate to the rear end of the platform, and puts the platform on the ground with the platform tilted backward. The present invention relates to a loading platform of a vehicle transporter configured to be loaded and loaded with a vehicle on the loading platform.
[0002]
[Prior art]
As this type of vehicle transport vehicle, there is a vehicle platform tilting type vehicle transport vehicle as shown in FIG. The vehicle transport vehicle is constructed by mounting a flat vehicle loading platform 3 behind the cab 2 of the vehicle 1 and placing the loading platform 3 on the vehicle body frame 1a by loading platform driving means (not shown). The carriage 3 is attached to the body frame 1a so as to be movable between a loading posture T (shown by a solid line in FIG. 6) and a rearward tilt of the loading platform 3 with respect to the body frame 1a. Further, at the rear end portion 3c of the loading platform 3, a left and right step board 4 is in a standing posture U (shown in FIG. 6 with a chain line) and a bridge posture D (shown in FIG. 6 with a solid line) in which the rear end portion 4a is suspended on the ground. It is attached so that it can rotate freely.
[0003]
The vehicle transport vehicle configured as described above is configured to load the vehicle 5 on the loading platform 3 in the following procedure. That is, in order to load the vehicle 5 on the loading platform 3, first, the loading platform driving means is driven to set the loading platform 3 to the loading posture T in which the loading platform 3 is slid and tilted rearward with respect to the vehicle body frame 1a. The board 4 is turned to a bridge posture D in which the rear end 4a is suspended on the ground (the state shown by the solid line in FIG. 6). In this state, the vehicle 5 can be loaded on the loading platform 3 by running on the step board 4. After loading the vehicle 5 on the loading platform 3, the left and right walking plates 4 are first rotated to the standing posture U, and then the loading platform 3 is moved to the traveling posture S on the vehicle body frame 1a (see the chain line in FIG. 6). If the vehicle 5 is fixed to the loading platform 3, the vehicle 1 can be transported by traveling the vehicle 1.
[0004]
Note that the inclination angle α of the loading platform 3 in this type of vehicle carrier is relatively high due to factors such as the total length of the loading platform 3 and the height of the body frame 1a, so that the front of the vehicle contacts the loading platform surface when the vehicle is loaded. Difficult to carry ordinary passenger cars was set at 11-13 °, and relatively low passenger cars were set at 8-10 °. Further, the inclination angle β of the left and right walking boards 4 was set to about 4 °.
[0005]
For this reason, in order to transport vehicles using this type of vehicle transport vehicle, when transporting ordinary passenger vehicles, prepare a vehicle with a bed inclination angle α of 11 to 13 ° and a passenger vehicle with a relatively low vehicle height. In the case of carrying, it was necessary to prepare and carry one having a bed inclination angle α of 8 to 10 °.
[0006]
[Problems to be solved by the invention]
However, when transporting a sports specification vehicle or the like having an extremely low vehicle height, the boarding angle of the vehicle 5 (the vehicle body inclination angle γ of the vehicle 5 at the time of loading the vehicle and the relative angle of the loading platform surface, etc.) (If the vehicle is large, the front of the vehicle will be in contact with the cargo bed surface and may be damaged), the tolerance is extremely small, about 5 to 6 °. Even if a vehicle transport vehicle with α of 8 to 10 ° is prepared, when the front wheel 5a having the most severe entry angle is located near the front end 4b of the step board 4 (in the state shown in FIG. (An angle γ is about 2 °) Since the boarding angle is about 6-8 °, which is larger than the allowable value of the vehicle 5, there is a problem that the front part of the vehicle is in contact with the cargo bed surface and cannot be loaded. .
[0007]
In view of the above-described conventional problems, the invention of the present application is a vehicle that can load a vehicle with a small allowable angle of entry, such as a sports specification vehicle, without the front part of the vehicle coming into contact with the load carrier surface and being damaged when the vehicle is loaded. The purpose is to provide a carrier platform.
[0008]
[Means for Solving the Problems]
The present invention has the following configuration as means for solving the above problems.
That is, the loading platform of the vehicle transport vehicle according to the present invention has a loading platform that can be tilted backward at the rear of the cab of the vehicle, and a rotatable step board attached to the rear end of the loading platform, and the loading platform has been tilted backward. The present invention is intended for a vehicle transport vehicle that is configured so that the step board is suspended on the ground in a state and the vehicle is loaded on the loading platform.
[0009]
The carrier of the vehicle transport vehicle according to the present invention comprises a cargo bed including a front cargo bed and a rear cargo bed having a single or a plurality of inclined cargo bed surfaces having an inclination angle different from that of the front cargo bed. The difference in inclination angle between the inclined carrier surface adjacent to the inclined carrier surface of the front carrier and the inclined carrier surface adjacent to the carrier surface of the front carrier is approximately in a state where the rear plate is tilted backward and the walking plate is passed over the ground. It is set to be equal.
[0010]
By configuring in this way, for example, when the rear cargo bed is constituted by a single cargo bed slope surface, a cargo bed slope surface having a substantially middle slope angle between both the step board and the front cargo bed is provided. Therefore, when the vehicle is driven on the platform and loaded on the platform, the leaning angle when the front wheel, which has been the most severe in the past, is located near the front end of the platform, becomes gentler at the rear of the platform. It gets smaller by that amount. For this reason, even a vehicle with a small allowable angle of entry, such as a sports specification vehicle, can be loaded without the vehicle front part contacting the cargo bed surface and being damaged.
[0011]
In addition, when the rear cargo bed is composed of a plurality of cargo bed inclined surfaces, a plurality of cargo bed inclined surfaces are provided with a substantially equal inclination angle difference between the step board and the front cargo bed. When loading up, when the front wheels move from the front end of the step board to the vicinity of the rear end of the loading platform, the boarding angle gradually changes. For this reason, even a vehicle with a small allowable angle of entry, such as a sports specification vehicle, can be loaded without the vehicle front part contacting the cargo bed surface and being damaged. In addition, the plurality of loading platform inclined surfaces are set so that the inclination angle difference between the inclined loading platform surfaces is small, the inclined loading platform surface adjacent to the loading platform surface of the front loading platform and between the inclined loading platform surface adjacent to the inclined surface of the step board. You may set so that the inclination angle difference between them may become substantially equal. In addition, when the loading platform inclined surface of the rear loading platform is composed of a large number of surfaces, the loading platform inclined surface changes substantially continuously, so that the vehicle can be loaded more smoothly.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS.
The loading platform of the vehicle transporter according to the present invention is characterized by the configuration of the rear portion of the loading platform, and the following description will focus on this characteristic portion.
[0013]
Reference numeral 10 denotes a vehicle loading platform 10 mounted on the rear side of the cab 2 of the vehicle 1, and the loading platform 10 is positioned on the vehicle body frame 1a by loading platform driving means (not shown). It is attached so as to be movable between a chain posture (shown by a solid line in FIG. 1) and a loading posture T (shown by a solid line in FIG. 1) that slides rearward and tilts backward with respect to the vehicle body frame 1a. Further, at the rear end portion 10c of the loading platform 10, the left and right stepboards 4 are in a standing posture U (shown by a chain line in FIG. 1), and a bridge posture D in which a rear end portion 4a is suspended on the ground (shown by a solid line in FIG. 1). It is attached so that rotation is possible. In addition, the inclination angle β of the left and right walking boards 4 is set to about 4 °, which is the same as that of the conventional walking board 4.
[0014]
The loading platform 10 includes a front loading platform 10a and a rear loading platform 10b. The loading platform inclination angle α1 of the front loading platform 10a is set to 8 to 10 ° as in the conventional loading platform 3 in the loading posture T. The rear cargo bed 10b is provided with a single cargo bed inclined surface 11 having an inclination angle different from that of the front cargo bed 10a (shown in FIG. 2). The inclination angle α2 of the loading platform inclined surface 11 is the same as that of the loading platform inclination angle α1 (8 to 10 °) of the front loading platform 10a in a state where the loading platform 10 is tilted backward and the left and right walking boards 4 are suspended on the ground. It is set to 6 to 7 °, which is a substantially intermediate inclination angle of the inclination angle β (about 4 °) of the step board 4.
[0015]
With this configuration, when the front wheel 5a of the vehicle 5 where the boarding angle becomes the strictest when the vehicle is loaded moves to the vicinity of the front end 4b of the step board 4 (shown in FIG. 2), the platform tilt angle α2 of the rear platform 10b. Is 6 to 7 °, which is gentler than the loading platform inclination angle α of the conventional loading platform 3, so that when the vehicle body inclination angle γ1 of the vehicle 5 is about 2 °, which is the same as that of the conventional loading platform, the boarding angle is about 4 Thus, even a vehicle with a small allowable angle of entry such as a sports specification vehicle can be loaded without the vehicle front portion contacting the cargo bed surface and being damaged.
[0016]
When the front wheel 5a of the transported vehicle 5 moves on the rear cargo bed 10b past the step board 4 as shown in FIG. 3, the vehicle is moved while the front wheel 5a moves from the rear edge to the front edge of the rear cargo bed 10b. The vehicle body inclination angle γ2 usually varies between about 2 ° and about 5 °. This change in the vehicle body inclination angle γ2 is a change to the safe side where the entry angle decreases, and the entry angle is It does not affect loading.
[0017]
Further, as shown in FIG. 4, the rear cargo bed 10b can be constituted by a plurality of cargo bed inclined surfaces 12a, 12b,. In this case, the left and right stepboards in the state where the load bed inclination angles α3a, α3b,... Of the respective load bed inclined surfaces 12a, 12b,. The inclination angle difference δ between the four inclined surfaces and the loading platform inclined surface 12a, between the loading platform inclined surfaces 12a and 12b, and between the loading platform surface of the front loading platform 10a and the loading platform inclined surface 12b is set to be substantially equal. That is, when the rear loading platform 10b has two loading platform slopes, the left and right stepboard 4 has an inclination angle β of about 4 °, and the front loading platform 10a has a loading platform inclination angle α1 of about 10 °, The inclination angles of the cargo bed inclined surfaces 12a and 12b may be set to about 6 ° and about 8 °, respectively.
[0018]
With this configuration, a plurality of loading platform inclined surfaces 12a, 12b,... Are provided between the walking plate 4 and the front loading platform 10a with substantially the same inclination angle difference .delta. The loading angle when the front wheel 5a moves from the front end 4b of the step board 4 to the rear loading platform 10b gradually changes when loading on the loading platform 10, so that the riding angle of sports specification vehicles, etc. Therefore, even a vehicle having a small allowable value can be loaded without causing damage to the front portion of the vehicle in contact with the cargo bed surface. The plurality of loading platform inclined surfaces 12a, 12b,... Are between the inclined loading platform surfaces (when the loading platform inclined surface is composed of two loading platform inclined surfaces 12a, 12b, between the loading platform inclined surfaces 12a, 12b). The inclination difference between the slopes of the step board 4 and the adjacent inclined carrier surface (the same, the inclined carrier surface 12a) and between the front carrier 10a and the inclined carrier surface (the same, the inclined carrier surface) are set. The inclination angle difference between the surfaces 12b) may be set to be substantially equal. Further, when the loading platform inclined surface of the rear loading platform 10b is constituted by a large number of surfaces, the loading platform inclined surface changes substantially continuously, so that the vehicle can be loaded more smoothly.
[0019]
In addition to the vehicle transport vehicle described in the above embodiment, there is a vehicle transport vehicle as shown in FIG. That is, a vehicle body tilting jack 15 is attached to the front portion of the vehicle 1 and the entire vehicle is tilted rearwardly with the jack 15, and a slide loading platform 17 attached to be extendable rearward from the rear end portion of the loading platform 16 is extended rearward. Thus, the loading platform of the present invention can also be applied to a vehicle carrier configured such that the rear end of the vehicle is grounded and the vehicle 5 is loaded by running on the left and right walking boards 4 in this state. In this case, the rear cargo bed is composed of a slide cargo bed 17 extended rearward of the vehicle, and when the slide cargo bed 17 is extended rearward of the vehicle, the rear end of the slide cargo bed 17 rolls or slides on the ground. The inclination angle α4 may be configured to be gentler than the inclination angle α of the loading platform 16.
[0020]
