Description
Technical field
What the present invention relates to is a kind of hydraulic tensioner proving installation, the dynamic bearer properties test board of especially a kind of internal combustion engine hydraulic tensioner.
Background technology
In the prior art, known technology is that hydraulic tensioner is widely used in the timing driving system of internal combustion engine, it forms oil pressure damping by internal hydraulic pressure element, absorb the vibration in transmission, the impact being subject to reduce each parts of kinematic train, in the serviceable life of prolongation timing driving system, guarantees the accurate and reliable of timing, and reduce transmission noise, improve the comfortableness of driving.
When design hydraulic tensioner, there are two problem points in the past:
1, because hydraulic tensioning is comprised of a plurality of parts, device complex structure.Dynamic bearer properties under the various rotating speeds of internal combustion engine changes greatly, and it will be very difficult that the design initial stage calculates dynamic bearer properties, and in the process of hydraulic tensioner inner chamber formation oil pressure damping, is subject to the impact of part processing precision, quality of fit.Calculated value and actual value have larger error, and whether without special checkout equipment, check design feasible, make the hydraulic tensioner of the design risk that comes into operation become large.
2, hydraulic tensioner belongs to parts of internal combustion engine, and its design effort environment must meet the requirement of internal combustion engine, therefore in the initial just necessary material of consideration of design own, motor oil viscosity at various temperatures, the variation of oil pressure.But too much because of the factor of impact, design difficulty is larger, without special checkout equipment, checks design, and the risk that hydraulic tensioner lost efficacy at extreme environment increases., this is the existing weak point of prior art.
Summary of the invention
Object of the present invention, be exactly for the existing deficiency of prior art, and provide the technical scheme of the dynamic bearer properties test board of a kind of internal combustion engine hydraulic tensioner, this scheme can be to the dynamic bearer properties test of hydraulic tensioner under various machine rotating speeds and various environment temperature, draw performance data, to determine whether the hydraulic tensioner of design meets internal-combustion engine system demand.
This programme is achieved by the following technical measures: the dynamic bearer properties test board of a kind of internal combustion engine hydraulic tensioner, include the hydraulic tensioner for testing, hydraulic tensioner is fixed on positioning tool, also comprises strong sensor, dynamic loading device and hydraulic system; Positioning tool one end connects with dynamic loading device; Hydraulic tensioner contacts with fixing power sensor; The internal oil passages UNICOM of hydraulic system and hydraulic tensioner; TT&C system respectively with power sensor, hydraulic system and dynamic loading system data UNICOM.
As this programme preferably: positioning tool and hydraulic tensioner are arranged in environmental cabinet; The adjustable the temperature inside the box of environmental cabinet; Environmental cabinet and TT&C system data UNICOM.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this scheme can be according to the actual condition characteristic of hydraulic automatic tensioner device, the dynamic perfromance power under corresponding engine speed, environment temperature, liquid oil pressure, it being subject to is carried out Real-time Collection, acquired character data.To determine whether designed hydraulic tensioner meets internal-combustion engine system.
As can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and progressive significantly, and the beneficial effect of its enforcement is also apparent.
