Abstract
The utility model discloses an improved rotary drum of a wheel testing machine. Periodic wavy lines are arranged on the outer surface of the rotary drum along the width direction of the surface of the rotary drum. The wavy lines are provided with circular arcs. Large wavy lines forming the macroscopic axis direction of the rotary drum are provided with small circular arcs. The rotary drum overcomes the problem that a conventional rotary drum is incapable of generating a large enough frictional force during the process of a wheel biaxial fatigue test; and simultaneously, the rotary drum also satisfies the conformance of experiment principles and real driving situations.
Description
Technical field
The utility model relates to a kind of tester for testing, relates to particularly for the wheel testing equipment.
Background technology
At present, both at home and abroad in automotive wheel testing experiment field, mainly use the equipment of three types.They are respectively: according to " wheel is the torture test radially " of international standard IS0 3006:2005 regulation.Used roller diameter does not wait from 1700mm to 3000mm, and the rotary drum circumferential surface is the carbon steel smooth surface.During work, the wheel tyre assembly is applied a radial force F
R, make pressure wheel on drum surface, rotary drum is at the uniform velocity rotated, wheel is at radial pressure F
RLower, rotate with rotary drum.
Utilize the beautiful and Italian Fiat of France regulation " deciding the load ratio biaxial fatigue test ".Used roller diameter is generally 1700mm, and the rotary drum circumferential surface is the carbon steel smooth surface.Can apply a radial force F to wheel during this equipment work
RWith a fleet angle or camber angle, make the not in one plane rotation of wheel and rotary drum, generate with each other a side-friction force, thereby make wheel produce a side force F
L
Utilize " the wheel load spectrum simulation test " stipulated among the SAE INTERNATIONAL standard SAE J2562.Used cylinder interior diameter does not wait from 800mm to 1200mm, and drum inner surface is the carbon steel smooth surface.During work, the wheel tyre assembly is placed in the cylinder, pressure wheel is produced radial force F at inner wall of rotary drum
R, produce side force F by changing camber angle
LWheel set rotates with cylinder under the radial force that constantly changes, side force.
Utilize first and second kind equipment, level and smooth drum surface can not produce enough large friction force, can not produce enough large side force.Utilize the third equipment can produce enough large side force, but test principle and actual wheel road driving differ too much, cause that wheel is stressed not to be met during with actual driving.
Summary of the invention
In order to overcome the deficiency of existing testing equipment, the utility model provides a kind of improved rotary drum, and this rotary drum has overcome the problem that existing rotary drum " can not produce enough large friction force ", has also reached the accordance when experimental principle is driven a vehicle with reality.The testing machine of this Novel barrate is housed, can does radially torture test, decide the load ratio biaxial fatigue test, can do again wheel load spectrum simulation test, realized one-machine-multi-function.
The technical scheme that its technical matters that solves the utility model adopts is: the wheel tester rotary drum, formed by carbon steel, along the drum surface Width periodic wave is set at the rotary drum outside surface, circular arc is set on the wave, forms on the large wave of rotary drum macroscopic view axis direction with small arc-shaped.
Specifically be of a size of: at drum surface 12-14 the cycle ripple that distributing, the degree of depth of ripple is 1mm, and bellows-shaped is level and smooth and tangent multi-section circular arc.On the wave molding in each cycle, 6 protruding small arc-shapeds that chord length is 6-8mm distribute.The height of projection of small arc-shaped is 0.2mm.There is the rounding of R2 the joint of circular arc and circular arc.
As optimization of the present utility model, at drum surface 16-18 the cycle ripple that distributing, the degree of depth of ripple is 1mm, and bellows-shaped is level and smooth and tangent multi-section circular arc.On the wave molding in each cycle, 8 protruding small arc-shapeds that chord length is 4-6mm distribute.The height of projection of small arc-shaped is 0.2mm.There is the rounding of R2 the joint of circular arc and circular arc.
The beneficial effects of the utility model are to improve the friction force between tire and rotary drum, so can obtain larger wheel lateral force at the trial.Overcome the restriction that can not load enough large side force, satisfied simultaneously radially torture test, decide load ratio biaxial fatigue test and load spectrum simulation test.Simultaneously, existing rotor system has been simulated the state of wheel road driving more really.
