Abstract
The invention discloses an impact-resistant test device of an off-the-road tyre tread. The impact-resistant test device comprises an off-the-road tyre and a power-driven rotary drum, wherein the axial lines of the off-the-road tyre and the power-driven rotary drum are parallel with each other and are positioned in the same horizontal line; under the action of a horizontal hydraulic mechanism, the off-the-road tyre presses on the rotary drum and rolls oppositely with the rotary drum; the opposite rolling surface of the rotary drum is provided with one or more bulges for simulating barriers; the diameter of the rotary drum is between 5 and 7 meters; the pressure range of the hydraulic mechanism is between 0 to 1,100 KN; and the length of the bulge is the same as that of the rotary drum, the width of the bulge is 50 to 80 mm, and the height of the bulge is 25 to 45 mm. The test device simulates the running state of the tyre on a ground surface with the barriers, thereby realizing an impact-resistant detection of the off-the-road tyre.
Description
(1) technical field:
The present invention relates to a kind of test unit, particularly a kind of off-the-road tyre tread impact test device.
(2) background technology:
The test of taking for detection carcass impact resistance is the test that runs away, tire is after being provided with certain mileage that travels on the road surface of barrier, check the degree of impairment (as " bulge " and cords break etc.) of carcass, judge the intensity of carcass with this, for the design of tire provides improvement project.
The test that runs away is only applicable to the detection of centering small tyre tyre surface, along with the development of off-the-road tyre to maximization, as the tyre rim nominal outside diameter is 25 "～33 " (inch), the tire overall diameter is less than 2 meters, it is 33 " more than (inch); the tire design overall diameter is more than 2 meters; single tire load is at the giant engineering machinery tyre more than 20 tons; because tyre load is big; the road traveling situation is complicated and abominable; the impact to tire tread is very big that single tire load is lower than 20 tons large-scale engineering machinery tire and tyre rim nominal outside diameter, on medium and small tire steel rotary drum, make durable or speed trial in the past and all can not well simulate actual operating mode, there is too big difference, do not have test effect, test does not have reference value yet at all.
(3) summary of the invention:
The objective of the invention is to have proposed a kind of off-the-road tyre tread impact test device, realize the detection of impact resistance when tire breaks the barriers with setting speed under assumed load, for the optimal design of tire provides foundation.
Can realize the off-the-road tyre tread impact test device of above-mentioned purpose, comprise that two axial lines is parallel and be in off-the-road tyre and rotary drum on the same horizontal line, rotary drum in the fixed position by power drive, off-the-road tyre is crimped on rotary drum by the effect of horizontal thrust mechanism, rotary drum drives tyre rotation and realizes that both are to rolling, described rotary drum be provided with one or more protrusions on the face to rolling, a plurality of projectioies can arbitrarily be provided with, and also can evenly be provided with.Off-the-road tyre and rotary drum are to rolling across in the journey, and described protrusion acts on the tire tread repeatedly, and the simulation tire running is having on the road surface of barrier.
Can be according to the protrusion of different operating modes design different sizes, the length size of general protrusion is respectively:, 50mm～80mm consistent with the rotary drum width and 25mm～45mm, each angle of protrusion is excessively slick and sly.
Described protrusion is arranged on the rotary drum with removably, and behind the dismounting protrusion, the present invention can be used as the off-the-road tyre fatigue experimental device and uses.
Be the high load capacity that model engineering machinery tire bears, described thrust mechanism is selected hydraulic mechanism for use.
The pressure limit design of described hydraulic mechanism is between 0～1100KN.
The diameter maximum of described rotary drum can reach 5m～7m.
Described rotary drum and protrusion are steel part.
Advantage of the present invention:
Off-the-road tyre tread impact test device of the present invention is a protrusion of setting up a simulation earth bulging on rotary drum, off-the-road tyre and rotary drum are when rolling, promptly having simulated tire is having the ground running status of barrier, the tire shock resistance is detected be achieved.
