SU143313A1 - Device for increasing the patency of the car - Google Patents

Description

Izzestny devices for improving the patency of vehicles, consisting of two independent balance trolleys. Balancing trolleys are mounted on the rear axle of the vehicle.

A disadvantage of the known devices is the large adjacency of their design, including additional brackets for the balance axle of the carriage.

The device made according to the invention, is devoid of this disadvantage. The essence of the invention is that the central wheel of the trolley is mounted directly on the drive axle of the car, which is simultaneously with the axis of the balance trolley.

FIG. Figure 1 shows the kinematic diagram of the proposed device for increasing the passage of the vehicle, side view; in fig. 2 - the same, top view; in fig. 3 schematically shows a GAZ-51 car equipped with the proposed device, side view; in fig. 4 - the same, top view; in fig. 5 - left trolley of the proposed device.

The proposed device for increasing the patency of a soft supporting surface to a standard 4x2 vehicle ensures complete preservation of the structure of all its components. When installing skis on the front steering wheels, a car equipped with the proposed fixture can be used as a snowmobile.

The device, with reference to the car GAZ-51. consists of TWO independently rocking balancer carriages 7 and 2 mounted on drive axle 3 of the vehicle. Drive 4 to the wheels of the cart - chain, from the main drive wheel. In order to increase the swinging level of the balancing carts, standard spacers and suspension struts of the GAZ-63 were introduced into the rear axle attachment to the springs.

a also progavkik as an additional spring, so that the front stroke and “set the carts up increased by 100 mm.

  The carriage consists of two spars: outer 5 and inner (arched cross-beams 7; leading drum 5, bar ¬ dd9v, central bearing housing, bearing housings of driven drums and sprockets 10.

The sequence of installation of the device on the car. It is assumed that the central drive wheels with arched tires are installed and secured with stubs.

1. A spigot // sleeve (fig. 3) is installed on the stocking of the rear axle, serving as the swing axis of the trolley.

2. A driving drum 5 with sprockets and a central bearing body is mounted to the rear axle hub.

3. Mounted trolley frame.

4. The driven drums are mounted with wheels mounted on them.

5. Mounted chain. Its tension is adjusted with the help of nuts by means of zint, welded to the bearing housing.

Full installation of the device on a GAZ-51 vehicle was carried out by 2 people in 3 hours.

Changes in the standard car GAZ-51, associated with the installation of the device:

1. Remove the spare wheel carrier and tool box.

2. The rear lamp with the license plate is transferred to the center of the body.

3. Dimension pointers are installed.

The main advantages of the proposed device are: simplicity of design, without requiring any significant changes in the design of the car, the possibility of making the device by the workshops of MTS, low weight, versatility.

The simplicity of the design is achieved by:

1. Application of wheels with arched tires.

2. Using a one-way chain drive from the main drive axle of the car, as a result of which there is no need to use additional power transmission units (transfer box, main gear, etc.).

3. Using the vehicle axle as a connecting link for the main drive axle, the dispensing unit and the supporting element for the left and right carriages (balance axle).

Such a device design ensures the complete preservation of all standard vehicle power units.

Sufficient adaptability to the conditions of motion is achieved:

1. Due to the use of wheels with pneumatic tires.

2. Due to the separate mounting of the left and right carriages on the balance axle (drive axle of the car), which enables them to swing relative to the balance axle (central wheels of the carts) independently of each other.

When driving on snow, the total increase in the support surface of the car with the proposed device is achieved by installing front skis wheels on the control wheels (the reference surface is inactive, the specific pressure on the snow is 0.09-0.10 kg1cm, and in the 6-arched fixture 1000X600 (at full load The specific pressure of the active SUPPORT surface on snow is 0.16-1-0.22 tfelcM. To improve the interaction with the support surface and reduce the resistance to movement, the ski and wheels on one side are arranged along one track. The width of the ski corresponds to wheel width

The proposed device was manufactured, mounted on a GAZ-51 car and tested on virgin snow in early 1961. The test results suggest that the GAZ-51 car, equipped with the proposed device, is capable (with a payload of up to 2 tons) to overcome the virgin snow of almost any depth, having a sufficient stock of gi for towing additional cargo (in particular, a sled trailer). Tests confirmed good performance and technical qualities both in off-road conditions and when driving on paved roads (highway, city).

The proposed device is recommended for introduction into the national household.

Subject invention

A device for improving the vehicle’s permeability, consisting of two independent balance traction carts mounted on the rear axle of the automobile, is distinguished by the fact that. In order to simplify the construction, the central wheel of the trolley is mounted directly on the drive axle of the car, which is also the axis of the balance trolley.
