FR2768974A1 - General purpose trailer, with double tipping action - Google Patents

Abstract

The double tipping trailer is constructed on a chassis (1), which is mounted so as to pivot on the end of the towing beam (4), around the axis (3). The chassis carries a hopper body (5), which is mounted so as to pivot around an axis (6), which is carried by a support arm, fitted at the rear end of the chassis. This second tipping motion is produced with the aid of a jack (7), and a mechanism (10) to lock the chassis to the towing beam.

Description

 The present invention relates to a vehicle, trailer type, double tilt, comprising a chassis supported by at least one pair of wheels and a bucket placed and articulated on said chassis.

 The device of the present invention allows the production of a double tilt vehicle with a low floor height. The vehicle includes a tilting to allow the loading of heavy goods (possibly by rolling), and a tilting to empty the contents of the bucket (gravel, earth etc).

 Currently trailers do not combine the two tipping and trailers with hydraulic tilting have a fairly high bucket height.

 The device according to the invention comprises a chassis articulated with respect to a coupling jib and a bucket articulated with respect to a chassis.

 The tilting of the chassis with its bucket is carried out either manually or using a hydraulic cylinder. The tilting of the bucket is only carried out using two hydraulic cylinders.

 The special feature of the vehicle according to the invention lies in the position of the hydraulic cylinders and of the pivot axes of the bucket.

 The hydraulic cylinders are placed on each side of the bucket.

Each cylinder is articulated at one end on the side member of the vehicle chassis and at the other at the upper part of the side flanks of the bucket.

 The two pivot axes connecting the bucket to the chassis are located at the rear, on each side of the bucket and in height relative to the floor thereof.

 This arrangement of the cylinders and pivot axes allows the production of tilting vehicles with low floor and low weight, because this design does not require reinforced chassis and skips.

The accompanying drawings illustrate the invention
Figure 1 shows the vehicle in road position.

Figure 2 shows the chassis and the body of the vehicle tilted backwards.

Figure 3 shows the body of the vehicle tilted in the emptying position.

Figure 4 shows the chassis locking system.

With reference to these drawings, the vehicle comprises a chassis (1) supported by at least one pair of wheels (2). The chassis (1) is articulated in (3) relative to a coupling arrow (4). This chassis supports a bucket (5) articulated in (6) relative to the latter. On each side of the bucket two hydraulic cylinders (7) are positioned. Each cylinder is articulated at (8) at its lower part on the frame rails (1) and at (9) at its upper part at the bucket (5). The locking on the coupling hitch is done in (10) by an adjustable locking which will be detailed below. 4. For large vehicles a hydraulic cylinder can replace or be associated with the locking system (10) this in order to facilitate the tilting of the bucket-chassis (5) (1)
Each changeover is chosen according to the desired use. Tipper-chassis tilting Fig. 2 is to rotate everything around the axes (3) until the rear of the bucket (5) touches the ground. The bucket, with its rear door lowered, thus forms an inclined plane which allows heavy goods to be loaded or rolled. After balancing the load, the body and the chassis are returned to their initial position and locked in (10)
The second tilting Fig. 3 consists in pivoting by lifting the bucket (5) around the axes (6) by supplying the hydraulic cylinders (7). Tipping allows a good emptying of the bucket, because the bucket takes a fairly pronounced inclined angle and the rear of the latter varies very little in height. The bucket returns to its initial position by its own weight, after defusing the hydraulic cylinders (7)
The adjustable locking system Fig. 4 consists of a conventional self-locking towing hook (11) fixed to the chassis (1) of the vehicle and a corresponding ball (12), extended by a filtered rod (13). The threaded ball-and-rod assembly is screwed onto the coupling arrow (4) at a determined location. The hook (11) and the ball (12) automatically lock the bucket-ch assembly located at the coupling arrow (4). By screwing or unscrewing the filtered rod (13) we increase or decrease the chassis distance (1) hitch arrow (4), which has the effect of varying the height of the hook (14) and therefore better positioning the trailer to the towing vehicle.

 This tilting device according to the invention can be adapted to trailers of any size and possibly to vehicles other than trailers.
