Description

(54) TRACK FOR WEAR TIRE VEHICLE TIRES

This invention relates to means of testing pneumatic tires of vehicles.

A device for testing vehicle tires for wear is known, containing a vehicle such as a vehicle equipped with test tires 1.

The disadvantage of this device lies in the high cost of testing, which is long in time under unstable test conditions.

A known track for testing tires contains a treadmill and a device for holding a vehicle on a treadmill 2.

However, in such a track it is impossible to carry out tire tests for wear under stationary drainage conditions, since the change in lateral forces is limited by the safe speed of the vehicle. Moreover, the tracks and mechanisms of the tires on the right and left sides of the vehicle are not provided on such tracks.

The purpose of the invention is to expand the functionality by testing

tires for wear in conditions of stationary exhaust, the creation of various lateral forces and the same operating conditions of tires and mechanisms of the right and left sides of the vehicle.

This goal is achieved in that the device for holding the vehicle is made in the form of a rail and a guide roller cooperating with it, housed in a housing connected to the frame of the vehicle mounted rotatably at different angles.

The drawing schematically shows the proposed track.

The tire test track contains a treadmill 1 and a device for holding the vehicle 2 along a path made in the form of a rail 3 and a guide roller 4 housed in housing 5. The latter is connected to the vehicle frame 6 mounted for rotation at different angles b relative to the rail. Treadmill 1 is placed on both sides of the rail 3, having end stops 7 at the ends.

The vehicle 2 with the test tires is positioned and fixed by the COM 5 at a predetermined angle 5. The wheels of the vehicle are mounted parallel to its longitudinal axis and locked in this position. The vehicle is driven, for example, by an internal combustion engine (not shown) and moves in a predetermined trajectory. Different side panels are set by changing the angle. The same operating conditions of the tires and mechanisms of the right and left sides of the vehicle are provided by changing the direction of movement of the vehicle relative to the rail 3. This occurs at the moment when the guide roller 4 touches the spring-loaded stop 7. Mechanisms for controlling the operating modes of the vehicle (not shown) including, for example, a reverse gear shift box, changes the direction of travel of the vehicle. When testing a series of tire sizes, several rails can be used to speed up the tests, with the vehicle being mounted on different rails at different angles. The proposed track allows vehicle tires to be tested for wear under stationary drift conditions, to create various lateral forces acting on the vehicle. In addition, the same operating conditions of the tires and mechanisms of the right and left sides of the vehicle are ensured by automatically changing the direction of movement, and the test times are reduced, which reduces their cost by an average of up to 25%. Invention A track for testing vehicle tires for wear, comprising a treadmill and a device for keeping a vehicle on a treadmill, in order to enhance its functionality by testing tires for wear under conditions of stationary removal, creating various lateral forces and the same working conditions of the vehicles and mechanisms of the right and left sides of the vehicle, the device for holding the vehicle is made in the form of a rail and a guide interacting with it o a roller housed in a housing associated with a vehicle frame mounted rotatably at different angles.
