RU2558499C1 - Device to increase flotation of vehicle - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to device intended for increasing the flotation of transport facilities. This device comprises wheel hubs to for axles with flanges thereon to support conical reduction gears engaged on sides by prop shafts. The latter are fitted in conical gearbox housing grooves so that spiders stay between the groove and conical gearing housing.

EFFECT: better flotation, simplified production and assembly.

Description

The invention relates to devices for increasing the patency of vehicles when moving them on an uneven surface, off-road, loose snow and dirt.

A device that increases the cross-country ability of the car, according to the patent of Germany DE N 3146511 A1 of 1981. In the said patent, the device for increasing the cross-country ability of the car contains removable wheels that are mounted on wheels, which are carts with track rollers, and sprockets mounted on the wheels that are covered flexible tape. To prevent the track device from turning in front and rear, the carts are attached to the body by springs with shock absorbers.

A device for increasing the patency of the car according to patent No. 2159193. In the said patent, the device for increasing the cross-country ability, the driving support device comprises a trolley pivotally mounted on the driving axis of the car and supporting elastic rollers covering the supporting rollers and the driving wheel of the vehicle, or a drum or sprocket installed in their place, and the non-driving supporting device includes a ski with support for the non-drive wheel and with fixation elements relative to it.

The main disadvantages of the device to increase the cross-country ability of the car is the large metal consumption and the complexity of manufacturing the device, the high cost, and there is no equipment for driving the car in a transport position on public roads.

The aim of the invention is to eliminate the above disadvantages of the device to increase the cross-country ability of a car, and more specifically, to reduce the metal consumption and laboriousness in manufacturing a device to increase the cross-country ability of a car, in addition, it is possible to convert the car into a transport position for driving on public roads.

To achieve this goal, a device is proposed for increasing the car’s cross-country ability, in which an axle is mounted on a flange to each wheel hub of a car’s wheel drive with a bevel gear reducer mounted on ball bearings, connected in pairs between each drive and driven gear cases on ball bearings , with a cardan shaft with splines, and so that the gearboxes do not rotate around the axes, they have grooves in which these cardan shafts are installed, while the cross of the cardan shaft is located row groove and the gearbox housing.

In FIG. 1 shows a General view of a device to increase the patency of the car.

In FIG. 2 shows a flange with an axis.

In FIG. 3 shows the installation of the driveshaft in the groove of the bevel gear housing.

The device for increasing the cross-country ability of the vehicle has flanges with an axis 1, FIG. 2, which are attached to the hubs of the car together with the wheel disks, on the axis 1 are mounted on bearings 2 of the bevel gear housing 3, in which the bevel gears 4 and 5 are placed, the latter is also mounted on the bearings 2. The bevel gears 4 are mounted on the axles 1 and are fixed there , conditionally not shown, bevel gears 5 are connected through crosspieces 6 by cardan shafts on splines 7. In order for gearboxes 2 to not rotate around their axis during operation and it is possible to rotate the car, cardan shafts 7 are installed in the grooves of the housing 2, FIG. 3, so that the crosses 6 connecting the cardan shafts 7 are between the housing 2 and the groove in the housing. Cases of bevel gears 3 have inspection covers 8.

A device for increasing the cross-country ability of a vehicle operates as follows, FIG. 1. Under normal driving conditions, flanges with axis 1, FIG. 2 are attached to the hubs of the car together with the wheel disks, and they do not interfere with the movement of the car on public roads. If it is necessary to overcome difficult sections of the road, then on flanges with an axis 1 are mounted on bearings 2 of the bevel gear housing 3, FIG. 1. To do this, remove the cover 8 and install the bevel gears 4 on the axis 1 and fix them there. It is installed on both sides of the car. At the same time, the front and rear wheels become leading in the car, which ultimately increases the cross-country ability of the car. Since the driveshafts 7 are located in the grooves of the cases of the bevel gear 3, and the crosses 6 are between the bevel case 3 and the groove of this case, there will be no turning of these cases around the axes 1, FIG. 3. At the same time, the entire system has the ability to freely copy the terrain and freely rotate the car in the right direction.

The use of a device to increase the cross-country ability of the car will increase the technical and economic performance of the car and reduce the cost of its manufacture.

Claims (1)

A device for increasing the maneuverability of an automobile, comprising axles with a flange mounted on each wheel hub with automobile disks and securing bevel gear housings on them, which are connected to each other by cardan shafts on each side, characterized in that the cardan shafts connecting the driving and driven wheels, are located in the grooves of the bevel gear housings so that the bevel gear housings do not rotate around the axis with the flange, and the crosses connecting the cardan shafts are located in the gap between the grooves and the bevel gear housing.
