PROTECTIVE DEVICE FOR THE BOTTOM OF THE ENGINE AND MOTOR COMPARTMENT OF THE CAR

To date, several millions of Niva cars have been produced by the Niva, which do not have factory protective devices for the lower part of the engine and the engine compartment to protect them from falling on them during the movement of water, dirt, stones, etc.

The lack of protection leads to the fact that water and dirt flying from under the front drive wheels fall on the first hinge of the driveshaft, the bottom of the engine, in the engine compartment and on all devices that are there. Dirt flies all the way to the hood. All this accelerates the wear of the corresponding components of the car.

Lean car owners “Niva try to fix this problem on their own, in particular, using tarpaulin and similar means that are unreliable and short-lived.

At the same time, protective devices for the bottom of the engine and the engine compartment of passenger cars are known, which are installed, in particular, on all models of Zhiguli cars.

The protective casing of Zhiguli automobiles is attached to factory-made technological threaded holes.

About a year ago, Tupipg began to produce protective devices for the bottom of the engine and engine compartment for Niva cars.

We make this technical decision as a prototype.

The specified protection is a casing that is attached to the back of the car through two bent eyes on the casing and in front with the help of an existing bolt that secures the protection of the oil pan.

According to the authors, the disadvantage of the design of this protection is the inconvenience of inspection, cleaning the space above the casing, as well as minor repairs. For such operations, it is necessary to completely disassemble all three fasteners of the protective casing.

"Niva, which can be used on the Niva cars, which were posted without protection.

The technical effect of the proposed utility model consists in creating easier access to the space above the protective cover and in the possibility of installing a protective cover on already wrecked vehicles, in particular Niva, without any structural changes in them associated with the installation of a protective cover. In this case, only the existing mounting resources of these vehicles are used.

The technical effect is achieved by attaching the casing to the anti-roll bars by means of split bushings made of elastic material, each of which is covered by a clip, to which, in turn, the rear part of the casing is attached.

The developed fastener system allows you to securely fasten the protective cover on the car, without changing anything in its design.

The protective casing is a flat sheet with a folding eye with an opening and an oil drain hole, which is blocked by a removable elastic plug. The protective cover through the hole in its front (eye) is mounted on an existing bolt that secures the protection of the oil pan. The protective casing through the holes in its rear part is attached to the anti-roll bar of the vehicle with bolts passing through a clip, which has an elastic element with a hole corresponding to the diameter of the anti-roll bar. The elastic element has a through cut to the landing hole. Due to this, the clip is put on the stabilizer bar indiscriminately.

Thus, the fundamental difference between the proposed technical solution and the prototype is the system for attaching the protective casing to the car: namely, the rear part of the casing is mounted on the stabilizer bar of the vehicle using a clip. Nothing, the clip has an elastic element with a hole corresponding to the diameter of the stabilizer bar, and the elastic element has a through cut to the hole. The optimal number of clips is sufficient for reliable casing fastening - two. In this case, the casing is attached at three points.

To increase the reliability of fastening the front of the protective casing, the authors propose to use the existing mounting points of the stretch marks to the front beam. In this case, instead of the existing two bolts of fastening of extensions

two adapters are installed, which are simultaneously fixed at one ends of the extension, and at the opposite - the casing.

The combination of these distinguishing features allows to ensure high reliability of fastening of the protective device in combination with the ability to install a protective casing on previously released cars. Thanks to the combination of these features provides easy access to the space above the protective casing. For access, it is enough to unscrew the nut from the bolt securing the casing in front and two nuts from the adapters, after which the casing can be turned around the bar of the anti-roll bar to the required angle. This rotation on the stabilizer bar is easily carried out due to the fact that the back of the casing is mounted on the bar using elastic elements, in the holes of which the casing rotates on the bar.

The proposed device is presented in FIG. 1 and consists of a protective casing with a removable plug 2 of an elastic element and three holes for attaching the front of the protective casing, two adapters 3, an existing bolt 4, two clips 5, each of which has an elastic element 6 with a hole corresponding to the diameter of the stabilizer bar and through section 7 (to the landing hole). The clips are worn on the arm 8 of the anti-roll bar. Each clip is connected to the protective casing with the help of two bolts 9.

The authors recommend the following procedure for installing a protective cover on a Niva car:

1. To put two elastic elements 6 on a bar 8 of the stabilizer bar of the car.

2. On the elastic elements 6 to install the casing 5.

3. Fasten the back of the casing 1 to the housings of the two cages in a known manner, for example, using two bolts 9 threaded through holes in the cages and the protective casing, and the corresponding nuts bolts.

4. Replace the two existing bolts securing the front beam extensions to the adapters 3.

5. Secure the front part of the protective casing with the existing bolt 4, which secures the oil pan protection, and two adapters by screwing the corresponding nuts on them.

The operation of installing a protective cover on the car is not difficult and takes no more than 10-15 minutes.

If you need access to the bottom of the engine, it is enough to unscrew the nut from the bolt securing the casing in front and two nuts from the adapters securing the front of the protective casing. After that, the casing can be rotated around the stabilizer bar, providing access to the engine.

Pa car "Beer 1980 vshuska, the author of the technical solution Smirnov VD installed the described protective casing in 1986. After that, the engine compartment with the engine became clean. At the same time, the front propeller and the front exhaust pipe are also protected.

It should be noted that the installation of a protective casing also improves the aerodynamic performance of the car.

Claims (3)

1. The protective device of the bottom of the engine and the engine compartment of the car, in particular ива Niva ’, consisting of a protective casing having fixing holes and an opening closed by a removable elastic plug, and a system for attaching the casing to the car, characterized in that the rear part of the protective casing is mounted on the stabilizer bar of the vehicle with the help of a cage, comprising an elastic element with a landing hole corresponding to the diameter of the stabilizer bar. 2. The protective device according to claim 1, characterized in that the elastic element has a through cut to the landing hole, which allows you to install the clip on the stabilizer bar without disassembling the stabilizer. 3.
