Abstract

The utility model relates to the technical field of automobile gearboxes, in particular to a front-row planet carrier and clutch oil pressure testing device which comprises a bottom plate (1), and a supporting structure is arranged on the top of the bottom plate (1). The front-row planet carrier is connected with an oil pump, and the oil pump is arranged on the supporting structure and connected with a pressure gauge. The electromagnetic valve oil way plate can provide mounting positions for the oil pump and the electromagnetic valve, and enables the electromagnetic valve to be communicated with an oil way in the oil pump; the electromagnetic valve oil way plate can be matched with the fixed baffle to provide stable support and fixation for the oil pump, so that the oil pump is firmly mounted on the device; a pressure gauge connecting hole is formed in the fixed baffle, a pressure gauge is installed in the pressure gauge connecting hole, and the pressure gauge connecting hole is communicated with an inner oil way of the oil pump, so that the pressure gauge can detect oil pressure of circulating oil ways of the oil pump, the front-row planet carrier and the clutch.
