Full-performance test stand for automobile automatic transmission machining oil pump

Abstract

The invention relates to an automobile parts manufacturing technology and aims to provide a full performance test stand for an automobile automatic transmission machining oil pump. A driving motor isarranged on a worktable, and the output end of the driving motor is sequentially connected to a torque speed sensor and the machining oil pump to be tested through a coupling; the machining oil pump is clamped and mounted on a valve seat by a pneumatic clamping device, the interior of the valve seat is provided with an inlet and outlet chamber oil passage, an oil inlet of the machining oil pump are connected to an oil inlet pipe through an oil inlet of the valve seat, an oil outlet of the machining oil pump are connected to an oil outlet pipe through an oil outlet of the valve seat, and the oil inlet pipe and the oil outlet pipe are connected to a main oil tank; an inlet temperature sensor and an inlet pressure sensor are arranged at a position, close to the valve seat, of the oil inlet pipe, an outlet temperature sensor and an outlet pressure sensor are arranged at a position, close to the valve seat, of the oil outlet pipe, and a noise sensor is mounted on the machining oil pump. Therotating parts can be mantled by a safety protection cover to play the role of safety protection; and by means of the combination use of a rod-less cylinder and linear guide rails, the machining oilpump is convenient to assembly and disassembly before and after a test.

Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, and in particular relates to a full-performance test bench for an oil pump of an auto automatic transmission. Background technique [0002] In recent years, with the rapid development of the automobile industry and people's pursuit of high-performance automobiles, higher and higher requirements have been put forward for the functions of automobile engines. As an important part of the automobile lubrication system, the oil pump provides guarantee for the normal operation of the engine, transports the oil to the engine, and plays a role in lubricating and cooling the various parts of the engine. The performance of the oil pump directly affects the performance and performance of the engine. Therefore, the oil pump must undergo strict performance testing before leaving the factory. [0003] The current oil pump test bench has the following problems: First, the pressure, flow and oth...

AI Technical Summary

Problems solved by technology

[0003] The current oil pump test bench has the following problems: First, the pressure, flow and other characteristics are measured with pressure gauges and flow meters, and when observed with the naked eye, the error is large and the accuracy is low; second, there are few test items, and some test items have the original test bench It cannot be completed; the third is that there is residual oil on the work surface, which is not neat and clean
