Abstract

The invention relates to a chain tensioner test bed which is in particular suitable for performance test of a timing chain tensioner of an automobile engine. The chain tensioner test bed mainly consists of a rack, an oil retaining mechanism, an oil supply system, a drive pushing mechanism, a tensioner supporting mechanism, a tensioner clamping mechanism and a computer control system. The test bed can test performances of three chain tensioners simultaneously. Vertical and horizontal tensioner clamping mechanisms are adopted by aiming at different types and positioning modes of the chain tensioner. In test, first, the chain tensioner is installed and clamped by the tensioner clamping mechanism. The tensioner supporting mechanism leans against the chain tensioner, and the oil supply system supplies oil to the chain tensioner. Meanwhile, the drive pushing mechanism acts on a plunger of the chain tensioner according to speed and stroke required by test. Performance test data of each chain tensioner are drawn, analyzed and stored by collecting real time pressure of a pull pressure sensor in the pushing process through a computer.

Description

technical field [0001] The invention relates to a test bench for a chain tensioner, which is particularly suitable for simulating the performance test of the timing chain tensioner of an automobile engine. Background technique [0002] The timing chain transmission system has been widely used in automobile engines. The timing chain transmission has the characteristics of accurate transmission ratio, high efficiency and long life. The chain tensioner is usually installed on the loose side of the timing chain, and the oil supply pump is connected to the chain tensioner through the oil pipe. The computer controls the oil supply pump to supply different oil pressures to the chain tensioner according to the requirements of the engine working conditions, so that it can Make the chain tensioner produce different tensions to ensure the tension and reliable operation of the timing chain. At present, there is no special test bench for chain tensioners, and companies usually verify an...
