Problems solved by technology

The traditional engine hydraulic transmission system verification has the following disadvantages: 1. The load loaded by the electric dynamometer verification can only rely on indirect calculation; 2. There is a difference between the electric power and the hydraulic action, which cannot reflect the hydraulic characteristics, and the verification results reflect untrue; 3. It is impossible to verify the compatibility between the engine and the hydraulic pump and the capability and reliability of the hydraulic pump

Abstract

The invention discloses a verification device for a hydraulic transmission system of an engine. The verification device comprises an oil tank, one or more oil inlet passages, a cooler, hydraulic pumps, overflow valves and a measuring and controlling unit, wherein the oil inlet passages are communicated with the oil tank; pressure sensors, temperature sensors and flow meters are connected into pipelines of the oil inlet passages; hydraulic oil in the oil inlet passages is cooled by the cooler and then enters the oil tank through an oil return passage; the hydraulic pumps are directly mounted on hydraulic pump mounting interfaces in the engine, and are connected to the oil inlet passages; the overflow valves are connected to the oil inlet passages, and used for providing analogue load of the verification device; the measuring and controlling unit is electrically connected to the pressure sensors, the temperature sensors and the flow meters, and used for recording pressure data of the pressure sensors, temperature data of the pressure sensors, and flow data of the flow meters. The verification device can be used for directly verifying the load conditions of the hydraulic pumps accurately.

Description

technical field [0001] The invention relates to the technical field, in particular to a verification device for an engine hydraulic transmission system. Background technique [0002] With the development of my country's agriculture, agricultural mechanization is becoming more and more popular, such as corn harvesters, wheat harvesters and other agricultural machinery and equipment. In order to meet the rapid development of agriculture in our country, the reliability of agricultural machinery and equipment is particularly important, especially the power source of agricultural machinery - the engine. Modern agricultural machinery requires the engine to have multiple power outputs, such as the front end and rear end of the engine, especially the hydraulic power is no longer realized through a chain or belt transmission mechanism, but requires the engine to directly provide a hydraulic pump installation interface in a direct drive mode Improve delivery efficiency. [0003] At ...
