Abstract

The invention relates to a test bed for a valve actuating mechanism of an engine with top-mounted cam shafts. The test bed comprises a test bed supporting trolley, and a cylinder-cover connection board, a front-end gear board and a motor which are fixed on the test bed supporting trolley, as well as a circulation oil path and an engine front-end gear. The motor simulates the rotating speed of theengine; and a front-end panel which is the same as a timing gear of the engine is designed and used for installing various tension wheels and idle wheels which are needed by the timing gear, so that an arrangement state of an actual working gear of the engine can be simulated. The motor is used as a power source, and a crank shaft timing wheel arranged on the motor drives a timing belt or chain so as to drive an admission cam shaft and an exhaustion cam shaft to work; and an actual working state of the valve actuating mechanism of the engine with two top-mounted cam shafts can be represented really, so that the performance test of the valve actuating mechanism of the engine can be performed. The test bed has the advantages that: the equipment is simple, the actual working state of the valve actuating mechanism of the engine with the two top-mounted cam shafts can be simulated effectively and really, and the accuracy of a test result can be guaranteed.

Description

technical field [0001] The invention belongs to the field of automobile testing, in particular to an overhead camshaft engine valve mechanism test bench. Background technique [0002] In the test of the valve mechanism of the overhead camshaft engine, since the actual working state of the valve mechanism of the overhead camshaft engine cannot be effectively and truly simulated, it cannot effectively and truly reflect the actual situation of the valve mechanism of the overhead camshaft engine. In the working state, it is impossible to accurately carry out the valve train test of the overhead camshaft engine. Contents of the invention [0003] The main problem solved by the present invention is to design a test bench for the test of the valve mechanism of the overhead camshaft engine, so as to reflect the actual working state of the valve mechanism of the overhead camshaft engine more effectively and truly, and accurately carry out double overhead camshaft engine. Camshaft ...
