The purpose of this utility model provides a kind of endless-track vehicle car load flexible drum testing device.Endless-track vehicle is difficult to carry some testing apparatuss with car when doing actual road test, and the effect of flexible rotary drum crawler belt is equivalent to the road surface of an activity.During test, endless-track vehicle is reached on the rotary drum crawler belt, drive the rotary drum crawler belt after the vehicle take-offs and rotate, vehicle is convenient to vehicle is implemented various tests with respect to but transfixion of ground.
Endless-track vehicle car load flexible drum testing device comprises two identical annular flexible rotary drum crawler belt, driving wheel, transmission case, raising speed case, dynamometer machine, clamping cylinder, front and back trussed shores.Article two, the rotary drum crawler belt respectively with about two driving wheels be meshed.Transmission case has two input ends, an output terminal, two input ends of transmission case respectively with about two driving wheels be connected, the output terminal of transmission case is connected with the raising speed case, the raising speed case is connected with dynamometer machine.Can implement braking to the rotary drum crawler belt by dynamometer machine, give the vehicle imposed load.
Whole drum track annular configuration triangular in shape, above one section be that active section is equal with the road surface, all the other two sections is non-working surface.The outside surface of rotary drum crawler belt has the thorn of carrying out, and prevents tested vehicle slip.The inside surface of every rotary drum crawler belt has some thrust wheels, two angle sheaves, a driving wheel and a tensioning system.
During test tested endless-track vehicle is reached on the active section of rotary drum crawler belt, the crawler belt of tested endless-track vehicle is contacted with the rotary drum crawler belt, fix with wire rope and front and back trussed shore respectively before and after the tested endless-track vehicle, prevent that tested vehicle from moving forward and backward; The effect of four clamping cylinders in both sides is to prevent that tested left and right vehicle wheel from moving, falling from test unit.After endless-track vehicle starts, carrying out between vehicle track and the rotary drum crawler belt under the effect of thorn and friction force, driving the rotary drum crawler belt and rotate together, vehicle is with respect to the ground transfixion.There is thrust wheel the below of active section, and thrust wheel contacts with the inside surface of rotary drum crawler belt and be free to rotate, and effect is the weight that supports tested vehicle; Respectively there is an angle sheave front and back end of active section, and the effect of angle sheave is to guarantee that the rotary drum crawler belt does not come off when work, and under the effect of tensioning system, with the rotary drum crawler tensioning.The cylindrical of driving wheel has tooth, be meshed with the rotary drum crawler belt, after the tested vehicle take-offs, the crawler belt of vehicle stings interlock mutually with the shoe of rotary drum crawler belt, drives the rotary drum crawler belt and rotates, and drives driving wheel again after the rotary drum crawler belt rotates and rotates, by transmission case with about two power of surveying driving wheels converge into one the tunnel, pass to dynamometer machine at last after raising speed case raising speed, the effect of dynamometer machine is that the rotary drum crawler belt is implemented braking, loads for tested vehicle.The raising speed case has different gears, can change the rotating speed of transmission case output, makes it to be complementary with effective working speed of dynamometer machine.
This test unit is comprehensive strong, can carry out various tests to endless-track vehicle, as: the test of car load tractive force, engine load characteristic, braking performance test, steering behaviour test, master clutch test, simulation walking test, operating rod and the test of pedal steering force etc.

Embodiment
Now, the utility model patent complete vehicle flexible drum testing mechanism for track-laying vehicle and test method thereof are described in further detail in conjunction with Figure of description 1 and accompanying drawing 2.Test mechanism comprises: front haulage post 1, two annular flexible drum crawler belts 2, clamping cylinder 3, transmission case 4, rear haulage post 5, raising speed case 6, dynamometer machine 7, see accompanying drawing 1.Agent structure is two endless track, comprising: ring-type rotary drum crawler belt 2, thrust wheel 8, tensioning system 9, angle sheave 10 and driving wheel 11, see accompanying drawing 2.
Article two, annular flexible drum crawler belt 2 is an equipment, and outside surface has the thorn carried out, be used to increase and the crawler belt of tested vehicle between friction force; The effect of front haulage post 1, rear haulage post 5 and clamping cylinder 3 is fixing tested vehicles; The effect of transmission case 4 is that the power that two flexible rotary drum crawler belts 2 produce is converged into one, and power is reached raising speed case 6; The effect of raising speed case 6 is the output speeds that change transmission case 4, is complementary with dynamometer machine 7; The effect of dynamometer machine 7 is to the test mechanism imposed load; The effect of thrust wheel 8 is to support tested vehicle; Tensioning system 9 plays the flexible rotary drum crawler belt of tensioning; The outside surface of angle sheave 10 has the gear teeth, and they are meshed with flexible rotary drum crawler belt, and angle sheave idle running only plays guiding and prevents that flexible rotary drum crawler belt breaks away from; The outside surface of driving wheel 11 also has the gear teeth, and they are meshed with flexible rotary drum crawler belt, and the axle and the transmission case 4 of driving wheel 11 link, and the moment of torsion that two flexible rotary drum crawler belts are rotated is delivered to transmission case 4.
