Example Embodiment

[0048] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.

[0049] The invention belongs to a cold engine test bench, that is, without starting the engine, the running condition of the engine is simulated, the performance of the camshaft and the cam is tested, the energy waste is reduced, the test cost is reduced, and the test reliability is improved.

[0050] The invention focuses on simulating the thermal environment of each main working interface of the camshaft mechanism, using lubricating oil of actual working temperature, and active load on the valve end, which more truly reflects the working condition of the engine, effectively detects the performance of the camshaft, and is used for testing purposes. Camshaft life and reliab...

Abstract

The invention discloses an engine camshaft standard working condition testing platform. The engine camshaft standard working condition testing platform comprises a driving system, a transmission system, an oil supply system, a rack, a valve loading system and a testing control system, wherein the driving system drives a camshaft to rotate through the transmission system, the oil supply system supplies lubrication to a cylinder cover, the rack is used for mounting each system of the testing platform and the cylinder cover, the valve loading system is used for imposing pressure on a gas exhaust valve and simulating the process of gas exhaust when the gas exhaust valve opens. The engine camshaft standard working condition testing platform can reflect the force condition of a cam under the working condition, and meanwhile, the temperature of lubricating oil is maintained in a temperature in a real working process, and the original performance of the lubricating oil is maintained. The engine camshaft standard working condition testing platform can simulate tests under different engine working conditions, and test the cam and the reliability of the performance of the camshaft in an all-around mode.

Description

technical field [0001] The invention relates to the field of engine testing, in particular to an engine camshaft quasi-working condition test bench. Background technique [0002] The engine camshaft is the core key part of the valve train, and its performance is directly related to the function and efficiency of the engine. The design and working conditions of the existing engine camshaft test bench are quite different, and it is difficult to simulate the real damage and life of the material. [0003] The patent application number is 201110060371.5 "A Test Bench for Valve Mechanism of Overhead Camshaft Engine". The test bench has a driving system, a transmission system, a lubrication system and a supporting body. The operation of the shaft, and lubricate the kinematic pair through the lubrication system to reduce friction and wear, and test the engine valve mechanism. Contents of the invention [0004] The test bench in the prior art can provide the camshaft with the con...
