Problems solved by technology
[0002] With the development of the automobile industry, its power system, especially the power system of four-wheel drive vehicles, has developed from a purely mechanical four-wheel drive structure to a mechanical and electrical hybrid structure and a pure electric four-wheel drive structure. Due to the independent control of the power of the four driving wheels, The current four-wheel drive system test is carried out on the two-wheel drive test bench, and only some basic strategy debugging can be carried out. However, the unique functions of the four-wheel drive system, such as free distribution of power between the front and rear axles, and free distribution of power between the left and right wheels, are not available in the existing The two-wheel drive test bench cannot be completed

Embodiment Construction
[0024] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as figure 1 A four-drive force test bench is shown, including a power assembly, a dynamometer, a control unit and a power supply system. The power assembly is connected to the dynamometer, the dynamometer is connected to the control, and the dynamometer is also connected The power supply system 16 (factory grid) is connected; wherein:
[0026] The dynamometer section includes four dynamometer units, which are connected to the drive wheel output shaft of the powertrain. Each dynamometer unit includes a dynamometer, a dynamometer inverter, and a speed torque sensor. The input end is electrically connected to the inverter of the dynamometer through a high-voltage power cable, and the output end of the dynamometer is connected to the drive output shaft of the powertrain under test through the flange of the s...

The invention provides a four-wheel drive power test stand comprising a power assembly, a dynamometer part, a control part and a power supply system. The power assembly is connected with the dynamometer part which is connected with the control part. The dynamometer part is also connected with the power supply system. With application of the test stand, free distribution of power between front and rear axles of the four-wheel drive power system assembly and free distribution of power between left and right wheels can be realized so that testing of the high-performance full-time and independent four-wheel drive system power assembly can be completed, and simulation of different road conditions, including skid and large angle climbing, can be completed via a central control system. Besides, test capability of current two-wheel drive power assembly test stands is also compatible.
Description
technical field [0001] The invention relates to an automobile drive test device, in particular to a four-drive force test stand. Background technique [0002] With the development of the automobile industry, its power system, especially the power system of four-wheel drive vehicles, has developed from a purely mechanical four-wheel drive structure to a mechanical and electrical hybrid structure and a pure electric four-wheel drive structure. Due to the independent control of the power of the four driving wheels, The current four-wheel drive system test is carried out on the two-wheel drive test bench, and only some basic strategy debugging can be carried out. However, the unique functions of the four-wheel drive system, such as free distribution of power between the front and rear axles, and free distribution of power between the left and right wheels, are not available in the existing A two-wheel-drive test bench cannot be done. Contents of the invention [0003] In view...
