Description

The device belongs to the automotive industry and can be used in the construction of trailers for cars.

Known uniaxial trailer with plywood and sides [See. Internet resource https: //е50.рф/stapel-dlya-perevozki-vodnoy-tekhniki-na-gruzovom-pritsepe-avtos/], on which you can install a slipway for transporting water equipment. In this design, it is not possible to make a trailer specifically for the transport of watercraft (without plywood and sides).

The known design of a car trailer [Patent RU No. 19012, IPC B62D 53/00, publ. 10.08.2001], consisting of a frame, drawbar, body, locking device, suspension, wheels, electrical equipment and reflectors, wheel protection. The spine-type frame has a transversely located rigid element and longitudinal elements that allow the suspension elements to be located within the frame thickness. The suspension is made in the form of a spring with a sprung that consistently comes into operation. Shock absorbers are located with a lateral slope. The locking device is mounted on the drawbar with the possibility of height adjustment. The drawbar is foldable with a quick-acting eccentric-type lock. The axles of the wheel hubs are mounted on the beam with the possibility of height adjustment. The front and rear sides are equipped with locks that allow them to swing up and down in height.

The known trailer for a passenger car has the disadvantage that it is very labor intensive and time consuming to bring the trailer into working condition.

Known trailer for a passenger car, taken as a prototype [Patent RU No. 2170189 IPC B62D 63/06, publ. 10.07.2001], which contains a body mounted on a frame, mounted on a wheel suspension, and having side and end flap, and a drawbar connected to the body. The drawbar is made Y-shaped with the ability to be detached from the front side of the body by means of quick-detachable attachment points equipped with a handle fixed in the bracket with nuts, a lock turning on a screw, and a stop for fixing the handle. The body frame consists of vertical struts fixed to the frame, the coating of which is made by hot-dip galvanizing. The body is made with the possibility of overturning relative to the suspension axis.

The disadvantages of the known trailer include the complexity and laboriousness of the technological process.

A common disadvantage of the known car trailers is the lack of functionality in terms of transportation of various types of goods and equipment. It is also possible to note the laboriousness and significant time required to bring the trailer to the required state, the inconvenience of access to the cargo when performing loading and unloading operations, the impossibility of replacing individual parts of the trailer without the use of welding and additional painting.

The technical challenge is to increase operational reliability, increase functionality and load capacity.

The technical problem is solved due to the fact that the trailer for a passenger car contains a frame, a drawbar, a locking device, a suspension including one or more movable axles, wheels, lighting fixtures, moreover, the frame is made with the possibility of installing lodgements made with the possibility of height adjustment, angle of inclination and distance between them, or plywood with ladders for securing cargo or plywood and sides.

Moreover, holes are provided in the longitudinal and transverse beams of the frame (fastening of plywood with ladders for fastening cargo or plywood and sides). And the installation of the lodgements, made with the possibility of adjustment in height, angle of inclination and distance between them, is carried out on the transverse beams of the frame.

The essence of the claimed trailer for a car is illustrated by drawings. FIG. 1 shows the view of the trailer "basic"; in fig. 2 type of trailer "water", including installed lodgments; in fig. 3 is a view of a platform trailer including plywood with stepladders; FIG. 4 type of trailer "flatbed", including plywood with sides.

A trailer for a passenger car contains a frame 1, a drawbar 2, a locking device 3, a suspension 4, including one or more movable axles (not shown in the figure), wheels 5, over which wings 10 are installed, lighting devices 14, 15, 16, 17 , 18, moreover, the frame 1 is made with the possibility of installing the lodgements 7, made with the possibility of adjusting the height, the angle of inclination and the distance between them, or plywood 8 with stepladders 9 for securing the load or plywood 8 and sides 11, 12, 13.

Frame 1 consists of interconnected longitudinal and transverse beams (not indicated in the figure).

Drawbar 2 is connected to frame 1 and is equipped with a locking device 3. Safety chains 6 are provided to ensure the operation of the locking device 3.

Suspension 4 with wheels 5 is fixed to frame 1. On the longitudinal beams of frame 1, above wheels 5, wings 10 are fixed to protect the trailer from contamination.

Lighting devices include reflectors 14, combined lights 15, fog lights 16, license plate lights 17 and parking lights 18.

It is possible to install one, two or more axles on the frame 1 of the trailer, which can be moved along the frame 1 due to the holes (not shown in the figure) made on the longitudinal parts along their entire length and located from each other at a distance that corresponds to the step of movement pendants.

Depending on the purpose of use and the type of cargo transported, it is possible to install one of the following options on frame 1: lodgments 7, adjustable in height, angle of inclination and distance between them; plywood 8 with ladders 9 for securing the load, which is rigidly attached to the frame 1; plywood 8 with sides 11, 12, 13. This increases the functionality of the trailer. Movable suspension 4 allows you to shift the center of gravity of the trailer, which makes it possible to configure the trailer to carry any load and increase the load capacity and stability. And the installation of lodges 7 or plywood 8 with ladders 9 or plywood 8 with sides 11, 12, 13 allows you to expand the trailer's capabilities in terms of transporting various types of goods and equipment.

The trailer, with 7 installed lodgments, adjustable in height, angle of inclination and distance between them, allows for the transportation of various types of water transport.

A trailer with installed plywood 8 with ladders 9 forms a platform trailer, with which it is convenient to transport building materials, household goods, bees, agricultural and other equipment, etc.

The trailer, with installed plywood 8 and sides 11, 12, 13, allows you to transport bulk cargo, various equipment, goods, etc.

The body (not shown in the figure) includes plywood 8, bolted, front 11, rear 12 and side 13 sides. The front 11 and rear 12 sides are fixed on the frame 1 with the possibility of folding. The side walls 13 are fixed without the possibility of folding.

Assembling a trailer for a passenger car is carried out by the following options (you can install one of these options):

1. On the transverse beams of the frame 1 mount the lodgements 7, made with the possibility of adjustment in height, angle of inclination and the distance between them.

Or

2. On the longitudinal and transverse beams of the frame 1, plywood 8 with ladders for securing the load 9 is mounted using the holes provided for this.

Or

3. On the longitudinal and transverse beams of the frame 1, plywood 8 is mounted with stepladders for securing the load 9 and sides 11, 12, 13, using the holes provided for this.

When uncoupled, the trailer can be in a horizontal position, if there is a rolling wheel. To bring the trailer to the working position, it is rolled up from the rear to the passenger car and the locking device 3 is connected to the car's hitch, increasing the reliability of the connection by means of safety circuits 6. The electrical equipment of the trailer is connected to the electrical equipment of the car.

Claims (2)

1. A trailer for a passenger car containing a frame, a drawbar, a locking device, a suspension including one or more movable axles, wheels, lighting fixtures, characterized in that the frame is made with the possibility of installing lodgments made with the possibility of adjustment in height, angle of inclination and the distance between them, or plywood with ladders for securing cargo or plywood and sides. 2. A trailer for a passenger car according to claim 1, characterized in that the frame includes longitudinal and transverse beams made with holes, to which the lodgements or plywood with stepladders or plywood with sides are attached.
