Description

 The invention relates to the automotive industry.

 Re-equipment of a car with a right-hand drive in a car with a left-hand drive can only be done by replacing or modifying components and assemblies of a car and placing them in new places in relation to the left-hand drive.

 At present, shifting the steering wheel on the right-hand drive to the familiar left side is a very expensive and technically difficult operation. In order to perform this operation, it is necessary to replace and completely redo many complex car components. It is necessary to rearrange the steering column along with its attachment points. It is necessary to rearrange the pedal group together with the brackets, the vacuum brake booster, and re-lay the tubes that fit to it. Rearrange the clutch also with the tubes. Rearrange the throttle cable. Inside, it is necessary to completely rearrange the "torpedo", the heating, ventilation and air conditioning system. It is necessary to transfer the tubes in the engine compartment to the air conditioner and stove, which must be increased or shortened. It is necessary to replace the wiper drive and optics. To transfer the necessary nodes to the left side, space is freed for them in the engine compartment, and the nodes installed there are transferred to the opposite side, respectively. All nodes must be fixed to a metal wall (motor shield) that separates the space under the hood of the car. On most right-hand drive cars, the wall has a substantially asymmetric shape, providing for the installation of certain units in certain places.

 Existing technologies for re-equipment of cars do not allow to perform the necessary work with the right quality in an acceptable time frame and with reasonable financial costs for re-equipment.

 The technical result consists in the development of technology for the conversion of the car, providing the necessary level of quality and reasonable price for the conversion of the car.

 This result is achieved by the fact that in the method of converting a car with a right-hand drive in a car with a left-hand drive, according to which the components and assemblies of a car used in a right-hand drive are replaced and / or modify for installation on a car with a left-hand drive, modify or replace new motor shield, modify the window sill by installing brackets on it in new places and install the window sill in an inverted position between the uprights.

 The motor shield can be modified by cutting out its right and left parts with the formation of the central part and replacing these parts with new ones or by performing changes necessary to rearrange and close unnecessary holes in the left and right parts.

 When modifying the window sill, the brackets cut earlier from the beam are installed in new places.

The essence of the conversion of a car with a right-hand drive in a car with a left-hand drive is as follows:
The technical process of car conversion includes the following main steps:
1. Dismantling the car.

 The specific type of work depends on the particular car, on the wishes and capabilities of the person who wants to convert the car. However, the most important criterion for choosing a list of works is quality assurance, which is necessary for registration with the State traffic inspectorates.

 To minimize the cost of refitting the car, it is proposed to use the old window sill, fixed by the corresponding end to the opposite pillar, i.e. fixed upside down.

 Brackets previously cut from the beam are welded to new places.

 Replacing the motor shield allows you to simplify the process of transferring components and assemblies to new places and avoiding the destruction of the car body number.
