Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
As depicted in figs. 1 and 2, embodiments of the invention, a kind of longitudinal stability coefficient test stand of four-wheel all-terrain vehicle, comprise test stand, pedestal device and suspender 6, test stand comprises stand 1, crossbeam 2, base 3 and ramp 4, ramp 4 is arranged on base 3 one end, stand 1 is arranged on base 3 two ends, and crossbeam 2 is arranged between stand 1, and pedestal device is arranged on the base 3, crossbeam 2 is provided with guide rail 5, and suspender 6 is arranged on guide rail 5.Pedestal device comprises two groups of shifting sledge devices 7, two groups of directive slide track devices 8 and pedestals, two groups of shifting sledge devices 7 and two groups of directive slide track devices 8 are arranged on base 6, pedestal comprises fixed base 9 and traveling platform 10, fixed base 9 arranges on the base 3 near the side of ramp 4, and traveling platform 10 is arranged on two groups of shifting sledge devices 7 and two groups of directive slide track devices 8.
Principle of work: be placed on by the front-wheel of vehicle on fixed base 9, trailing wheel is placed on traveling platform 10, and the afterbody of vehicle is connected with suspender 6.Four-wheel all-terrain vehicle (ATV) tire pressure is necessary for the tire pressure be applicable to when generally using of manufacturer's suggestion.If manufacturer provides more than a kind of suggestion air pressure, a minimum atmospheric pressure value so should be got; Except fuel oil is not less than 3/4 of capacity, all fluids (machine oil, liquid coolant or analog) all should be filled it up with.Four-wheel all-terrain vehicle (ATV) should be unloaded, without operator, without goods and other attachment devices, deflecting roller should keep to dead ahead, adjustable mechanical suspension system parts should be set at designated value when manufacturer consigns to dealer, mechanical suspension parts should by the mode of locking, and make unloaded four-wheel all-terrain vehicle (ATV) on level ground, sprung parts is still at identical position and identical displacement, measure and record wheel distance L, the length value recorded should be accurate to ± 5mm, measure and record front and rear wheel load weight, Wf is front-wheel load total amount, and Wr is trailing wheel load total amount, and during test, vehicle is answered horizontal positioned and meets the requirements, and the gravimetric value recorded should be accurate to ± 0.5kg, the value that said method obtains as follows
calculate and record calculated value: the advance of L1=from rear axle to center of gravity, measure and record the vertical height Rr of rear axis to ground, during test, vehicle is answered horizontal positioned and meets the requirements, and the height value recorded should be accurate to ± 3mm or ± 1.5%, measure and record equilibrium angle α, the process obtaining this measured value should be as follows: four-wheel all-terrain vehicle (ATV) is placed in horizontal surface, when not using parking brake and use any type mode of braking, car front portion is rotated up centered by hind axle, until vehicle lands with trailing wheel reach balance, measuring and recording the angle that four-wheel all-terrain vehicle (ATV) rotates through is α value, the angle value recorded should be accurate to ± and 0.5 °, if four-wheel all-terrain vehicle (ATV) afterbody is provided with any appurtenances, such as drawing bar or afterbody coupling arrangement or hook, thus affect tailstock kiss the earth and affect vehicle arrival equilibrium state, vehicle should be placed on sufficiently high pedestal to eliminate interference, repeated test process, and checking whether twice test result differs within 1.0 °, if not, test twice so again, and with the arithmetic average of result to test for four times as net result, finally calculate longitudinal stability coefficient value:
.
