The standard body of the CA7130 matching powertrain is supported by four support columns with adjustable height (Z-axis), the body is adjusted to the horizontal position, and the fixtures described above are respectively mounted on the left and right front suspensions. Support position. An engine with an adjustment frame is placed in the engine compartment of the vehicle body. The engine support frame of the engine adjustment frame can adjust the movement of the engine along the X-axis and Y-axis and the rotation around the Z-axis. The adjustment bar can adjust the movement of the engine along the Z-axis. The adjustment of the engine support frame (movement along the X axis and Y axis) can adjust the rotation of the engine around the Y axis and the X axis by adjusting the movement of the engine along the X axis, Y axis, and Z axis and around the X axis and Y axis. Rotation of the Z-axis, so that the end structure of the mandrel 1', 2' adapt to the Tianjin transmission, through the fixture sleeve into the Tianjin transmission half shaft output spline hole, and record the length of the mandrel 1 ', 2'Y axis direction . Through the above three steps, you can compare the positions of the power output points of the CA7160 and CA7130. From the above comparison, the CA7160 design and calculation and the CA7130 power output point of the X axis, Z axis coordinates exactly the same, Y axis coordinates as long as the mandrel 1, 2 and the mandrel 1 ', 2' the length of the calculation can know The final calculation shows that the Y axis coordinate of the CA7130 power output point is 26.4 mm to the left than the Y axis coordinate of the CA7160. One of the advantages of this comparative test method is that it simplifies the processing of complex problems, and the design of the various designs, such as the design of the suspension point, is carried out based on the layout of the actual vehicle. The accuracy is within the range of 0.5 mm. Another advantage is that the lengths of the shafts can be compared using the lengths of the mandrels 1, 2 and the mandrels 1', 2'. The lengths of the half shafts calculated from the wheel axle jumps and the half shaft lengths calculated by the wheel jumping action are only The difference is 0.2mm, which is a good verification of the critical dimension (length dimension) of the critical part (half-axis). The power steering system successfully matched the CA7160 with a power steering system, while the CA7130-matched 8A-FE engine did not match the original design of the power steering pump. In order to solve this problem, a variety of structural methods were discussed: (1) The power was first selected through calculation. Power steering pump. If the CA7130 still uses the power steering pump of the CA7160, the gear train parameters. Power steering pump speed (n booster pump = R crankshaft n crankshaft / R booster pump) calculation result. Model R crankshaft (mm) R booster pump (mm) crankshaft idle speed (r/min) crankshaft maximum speed (r/min) model booster pump idle speed (r/min) booster pump maximum speed (r/min) CA71609146875CA71308687400 The pump speed reaches 2500r/min, the oil pressure reaches 7~8MPa, and the check valve opens to make the internal oil circuit of the oil pump connected, thus limiting the oil pressure; In addition, the power steering pump also uses a flow control valve to control the high speed. Traffic. Therefore, the rotational speed of the power steering pump at the highest engine speed does not affect the normal operation of the steering assist pump. It can be concluded that the CA7130 matching CA7160 power steering pump is completely feasible. (2) Followed by the installation of the power steering pump for the power steering of the wheel train. Due to the structural characteristics of the engine and the spatial dimensions of the CA7130 engine compartment, a pulley with the same diameter as the crankshaft belt is used as the power output wheel in addition to the water pump pulley. The power steering pump bracket and belt are designed using the mounting holes in the engine block. Adjust wheel brackets. (3) The last problem is the ECU problem of the electronic control system. Since the ECU does not have a steering assist mode, the power steering power pump needs to consume power to make the engine work unsteady. The power steering pump has a pressure switch. When the power steering pump starts working, the switch turns on the output electrical signal. Input the ECU fog lamp switch input signal, so that when the power steering pump works, the ECU speed is increased to make the engine work smoothly. Through the above three steps, the CA7130 power steering system has been successfully matched.
