The invention relates to transport, namely, towing devices, and can be used in towing devices for cars with hitch ball type.

You know trailer hitch for passenger cars in the Russian Federation patent No. 2020081, CL 60 D 1/06, 1/14, 1994, It contains a hitch ball mounted on a bent pin, connected with the flange. A flange attached to the longitudinal beam. The beam is bent at 1/3-1/4 of its length in the direction transverse beams and bonded with her several triangles connection with cylindrical samples on the hypotenuse, the mating with the cross-beam, and the legs of large - longitudinal beam, two amplifying elements, fastened to the cross bar and triangles communication with stud fastening a safety device and plug. The transverse beam is provided with fastening elements that interact with the towing eyelets car. The longitudinal beam is provided with a semicircular mounting bracket installed on 1/3-1/4 of its length and mounting option are turned down by 1/2 to 1/3 of the diameter of the beam and fastened to the panel of the car body.

However, this device is a complex welded (one-piece) construction that does not meet international standards.

You know trailer hitch for flowing what about the car according to the patent of Russian Federation №2025292, CL 60 D 1/14, 1994, adopted by the applicant for the prototype and containing a control field, which is fixed to the longitudinal beam. The latter is rigidly connected to the cross bar by two triangular brackets. Each bracket is made accordingly to ensure manufacturability. The plug connector is installed on the flap, which is connected to the cross bar.

However, this design is a one-piece, welded, contrary to international operating conditions of the device has insufficient reliability and uncomfortable during installation.

The technical task of the invention is to provide a collapsible trailer hitch that meets international standards, is easy to manufacture and easy to mount on the car.

The problem is solved in that in the proposed solution the cross member provided with a bracket for connection with the longitudinal beam and the fastening elements of the cross member to the car body is made of two rigidly interconnected, bent parts, the longitudinal beam is made detachable, has front and rear part, the front part is curved and provided with a bracket for mounting on the bottom of the body of the car and the flange, the rear part has a flange for detachable connection with the front flange of the longitudinal beam, and coupling the ar mounted on the rear part, moreover, the bracket cross is designed for installation flanges front and rear longitudinal beams and connecting them with the cross member by means of detachable connections.

In addition, the hitch ball is made removable.

figure 2 - cross member Assembly with bracket and fasteners;

figure 3 - longitudinal beam in a split position;

figure 4 - cross section a-a in figure 1, a fragment of the mounting cross-beams and longitudinal beams;

figure 5 - cross section B-B in figure 2;

figure 6 - cross section b-b In figure 2.

Trailer hitch for a motor vehicle includes a cross member 1 with the fastening elements 2 and 3 cross 1 to the car body, the longitudinal beam 4 that is connected to the cross member 1, and the coupling ball 5, mounted on the longitudinal beam 4. Items 2 and 3 installed in pairs at each end of the cross member 1, and each made of two rigidly interconnected curved on the radius of the parts.

The cross member 1 provided with a bracket 6, is rigidly mounted on the middle part, and the bracket 6 has a plate 7 under the plug. Longitudinal beam 4 is made detachable and has a front 8 and rear 9 parts. The front part 8 are curved and provided with rigidly mounted on the bracket 10, which serves for installation on the bottom of the body of the car, and the flange 11, the flange 11 secured additionally by a stop 12. The rear part 9 of the longitudinal beams 4 is equipped with a mounting seat 13 for coupling the ball 5 and the flange 14 for detachable connection with the flange 11 of the front part 8 of the longitudinal beams 4, and a hitch ball 5 is installed in the seat 13 with the possibility of removal by threaded connection. In addition, on the rear part 9 mounted element 15 for connecting a safety element when towing. The flange 14 fixed to the rear part 9 by means of the stop 16. Moreover, the bracket 6 of the cross member is designed for installation flanges 11 and 14 of the front 8 and rear 9 parts of the longitudinal beams 4 and connecting them with each other and with the cross member 1 by means of screw connection 17. And the rear part 9 of the longitudinal beams 4 are made with the possibility of removal from the device in the case when there is no need for towing, which is compliance with international standards of operation towing devices for cars.

The inventive device is made with possibility of installation on the floor of the body of the car by means of the bracket 10 of the front part 8 of the longitudinal beams 4 and fastening elements 2 and 3 cross 1 at the regular places marked on the bottom of the body of the car.

Installation of a trailer hitch on a motor vehicle shall exercise the following about what atom.

The cross member 1 with fasteners mounted in the regular places 2 and 3 on the vehicle body and nazhivljajut the bolts 18. The front part 8 of the longitudinal beams 4 by means of a bracket 10 mounted on the vehicle and also nazhivljajut the bolts 18. Then take the rear part 9 of the longitudinal beams 4 with coupling ball 5 and the flange 14 africasouth it with the bracket 6 of the cross member 1, and with the other hand to the bracket 6 is attached to the flange 11 of the front part of the longitudinal beams 4. After that, the flange 14, the bracket 6 and the flange 11 are connected with bolts 17. Then tighten all screws 18 mounting the device to the car body and the bolt 17. The device is installed.

When not towing, the rear part 9 of the longitudinal beams 4, together with the coupling ball 5 is removed, razvitii the bolt 17. After removing the rear part 9 of the front part 8 is fastened to the cross member 1 by the same bolts 17. Thus the goals set requirement.

The use of the proposed solution has allowed us to create a collapsible trailer hitch that meets international requirements, is easy to manufacture and convenient for installation and operation.

1. Trailer hitch of an automobile containing the crossmember with fasteners to the car body, trailing alku, connected to the cross member, and a hitch ball mounted on the longitudinal beam, wherein the cross member is equipped with a bracket for connection with the longitudinal beam and the fastening elements of the cross member to the car body is made of two rigidly interconnected curved parts, the longitudinal beam is made detachable, has front and rear part, the front part is curved and provided with a bracket for mounting on the bottom of the body of the car and the flange, the rear part has a flange for detachable connection with the front flange of the longitudinal beam and the hitch ball mounted on the rear part, and the bracket cross is designed for installation flange the front and rear longitudinal beams and connecting them with the cross member by means of detachable connections.

2. Trailer hitch according to claim 1, characterized in that the hitch ball is made removable.
