Abstract
A kind of automobile electric power-assisted steering is performance test bed, comprise removable stand, be connected with the steering wheel of torque sensor, PICO rack, the steering column that rotary angle transmitter is installed connects steering gear by connecting link, the other end of steering gear is connected with shaft coupling and digital torque sensor, between magnetic powder brake and digital torque sensor, is provided with reduction gear.The beneficial effects of the utility model are: the degree of accuracy that has improved test result, increase the practicality of test board, can complete more dependence test such as function test, input-output characteristic test, the test of power-assisted current characteristics, reverse impact test, the test of unloaded rotating torque, return positive attribute testing and the tests such as test of reporting to the police; And be not subject to the restriction of external environment condition, can carry out anywhere or anytime automobile electric power-assisted steering performance test education and instruction or producer's related experiment.
Description
Technical field
The utility model relates to a kind of automotive practical-training equipment, relates in particular to a kind of electric power steering performance test bed.
Background technology
Traditional electric power steering is performance test bed is generally all the mode that adopts manual direct control, be difficult to by the restrictions such as external environment condition, handling safety degree, cost price universal; Traditional electric power steering performance test is all to adopt the method loading step by step mostly on the other hand, and differs larger between two adjacent loading ranks, and test result often degree of accuracy is not high, can not better test the performance of automatic transmission.For a long time, lack a kind of higher testing precision that both had on market, the electric power steering that can generally use in automobile education and instruction or producer's real training is again performance test bed.
Summary of the invention
For the problems referred to above, the utility model provides a kind of higher testing precision that both had, and a kind of electric power steering that can generally use in automobile education and instruction or producer's real training is again performance test bed.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of electric power steering is performance test bed, comprise removable stand, steering wheel, PICO rack and steering column, steering column upper end is provided with rotary angle transmitter, and the bottom of steering column connects steering gear by connecting link, the other end of steering gear is connected with shaft coupling and digital torque sensor, between magnetic powder brake and digital torque sensor, is provided with reduction gear.
The described rotary angle transmitter one end electrical connection steering wheel that is arranged on steering column upper end.
Described test board power supply used is Iarge Power DC Voltage Regulator.
Described PICO rack is that the driver of capacitance plate, industrial computer, data collecting card, D.C. regulated power supply, magnetic powder brake and signal generator unit are concentrated to the machine of being integrated that is positioned to.
The driver of described magnetic powder brake is provided with digital regulated interface.
The beneficial effects of the utility model are: the degree of accuracy that has improved test result, increase the practicality of test board, can complete more dependence test such as function test, input-output characteristic test, the test of power-assisted current characteristics, reverse impact test, the test of unloaded rotating torque, return positive attribute testing and the tests such as test of reporting to the police; And be not subject to the restriction of external environment condition, can carry out anywhere or anytime automobile electric power-assisted steering performance test education and instruction or producer's related experiment.
