Embodiment
In Fig. 1, this hydraulic pressure 3-4 passage ABS inertial test table comprises running under braking master cylinder P5, running under braking master cylinder P5 is connected with source of the gas M by tracheae, running under braking master cylinder P5 by tracheae be that brake pressure propulsion cylinder PY2 is connected, brake pressure propulsion cylinder PY2 is connected with two-chamber hydraulic total pump PY1, and two-chamber hydraulic total pump PY1 is connected with the 5th oil supply hole 5, the 6th oil supply hole 6 of ABS hydraulic pressure regulator HCU by oil pipe.
The first oil outlet 1 of ABS hydraulic pressure regulator HCU is connected with the assembly WH1 of Thrustor with the near front wheel by oil pipe, the second oil outlet 2 of ABS hydraulic pressure regulator HCU is connected with the assembly WH4 of Thrustor with off hind wheel by oil pipe, the 3rd oil outlet 3 of ABS hydraulic pressure regulator HCU is connected with isolation valve M1 mono-end by oil pipe, the isolation valve M1 other end is connected with the assembly WH3 of Thrustor with left rear wheel by oil pipe, the 4th oil outlet 4 of ABS hydraulic pressure regulator HCU is connected with the assembly WH2 of Thrustor and is connected with communication valve M2 mono-end by oil pipe with off-front wheel by oil pipe, the communication valve M2 other end is connected with the assembly WH3 of Thrustor with left rear wheel by oil pipe.
The utility model has adopted the ABS hydraulic pressure regulator HCU of the structure of 4 passages, by isolation valve M1, communication valve M2, switching can make the inertial test table mode of operation become 3 passages or 4 channel patterns.
Transfer principle is as follows:
During 4 channel pattern, isolation valve M1 connects, and communication valve M2 closes.Now the oilhole of ABS hydraulic pressure regulator HCU with the annexation of pipeline is: the first oil outlet 1 is connected with the near front wheel, and the second oil outlet 2 is connected with off hind wheel, and the 3rd oil outlet 3 is connected with left rear wheel by isolation valve M1, and the 4th oil outlet 4 is connected with off-front wheel.

The pipeline wheel definition of the first oil outlet 1 is identical.
The second oil outlet 2 pipelines are defined as off-front wheel in 3 channel architectures, and 4 channel architectures are defined as off hind wheel.
During the 3rd oil outlet 3 pipeline 3 passage, not existing, is left rear wheel during 4 channel architecture.
The 4th oil outlet 4 pipelines are defined as left and right trailing wheel in 3 channel architectures, and 4 channel architectures are defined as off-front wheel.
The off-front wheel position that can be summarized as 3 channel architectures is off hind wheels of 4 passages, and the off hind wheel position of 3 channel architectures is off-front wheels of 4 passages.
On inertial test table, the position of wheel can arbitrarily define, so this utility model can realize the conversion of 3 passages and 4 passages.
