Description
Technical field
What the present invention relates to is the experimental set-up of attendant equipment performance on a kind of vehicle, and particularly a kind of four cylinder drive-type vehicle electric element equipment dependability test cell belong to the vehicle test field in the mechanical engineering.
Background technology
The heavy duty truck that is used for factories and miness, building irrigation site loose cargo transport, usually because its abominable road running mode causes the reliability failure and the infantile failure of vehicle electric element equipment, this motor road test method national standard is proposed to carry out the test or the simulation laboratory test of automobile reliability, durability, be suitable for quality assurance and control device under the over-the-road transportation condition with the car load electric system that provides vehicle to comprise each assembly of electric equipment such as gauge panel, combined switch, connection box, wire harness, car light, motor.For dillies such as cars, the method that realizes this requirement can place vehicle integral body on a kind of indoor universal hydraulic servo vibrobench together with the electric equipment that has assembled in it, make road vibration under the vehicle simulation road driving condition by its hydraulic actuating cylinder from bottom effect tire mode, thereby the reliability, the durability that carry out vehicle electric element equipment detect test; But for other various types of heavy duty truck heavy-dutys vehicle, because own wt is often all more than tens tons, existing universal test bench can't provide corresponding vibrotechnique condition at all, do not have this type of huge indoor vibrobench yet, therefore can't carry out the detection test of heavy-duty vehicle electric equipment reliability at present; And if carry out vibration reliability, durability test under the outdoor real vehicle road driving state, then corresponding experimentation cost height, cycle are long, and test condition is difficult controls, and also do not have the comparability and the repeatability of experimental investigation.Find by literature search, China Patent No. is: 87206586, name is called: the utility model patent of automobile performance test platform, its readme is for " main rigid plane by car body bearing set, four energy rotations substitutes road surface and torque compensation motor and substitutes the road surface rotating mechanism and forms; in order to improve measuring accuracy; substitute the road surface and adopt the both sides that are fixed on the chain to have the anchor plate structure of shaggy tooth; shock absorber is housed; also adopted the caterpillar wheel that has groove on anchor plate, and the flexible oil groove of annular corrugated formula is housed between chain and anchor plate.This test cell can the various motions of simulated automotive, have advantages such as measuring accuracy height, volume are little, are not only applicable to the vehicle performance test of miniature car, also can be used for autotruck and wheeled construction machinery that many vehicle bridge drive.Though " the various motions of this utility model energy simulated automotive, its " road surface " can not produce the vibration operating mode for rigid plane substitutes the road surface, therefore can't carry out reliability, the durability test of heavy-duty vehicle electric equipment; Find reliability, the durability test device to simulate actual operating conditions, to be used for the heavy-duty vehicle electric equipment up to now, so such The Application of Technology scope is very limited.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of four cylinder drive-type vehicle electric element equipment dependability test cell are provided, the universal hydraulic servo vibrobench of having eliminated prior art can't provide the vibration output of high load capacity, and the automobile performance test platform of other type can not produce the deficiency of vibration operating mode, enable to apply tens of thousand Ns of above vibrational loadings and can carry out analogue test to vehicle electric element equipment indoor, thereby changing existing all kinds detecting test of vehicle experimental set-up can only carry out the test of light-duty vehicle body vibration or can only simulated automotive variously travel motion and technical limitation that can not the suffered vibration of simulated automotive satisfies heavy duty truck and other heavy-duty vehicle and comprises gauge panel, combined switch, connection box, wire harness, car light, each assembly performance of electric equipmenies such as motor detects the requirement of test.
The present invention is achieved by the following technical solutions, the present invention mainly comprises: base plate, four hydraulic rams, upper hinge bearing, rocker bar bearing, chassis ridgepole down, four hydraulic rams are arranged substantially vertically, forward and backward each two, its cylinder status is not connected and fixed by four following rocker bar bearings and base plate, the piston rod mouth of four hydraulic rams connects with chassis ridgepole by four upper hinge bearings respectively, each assembly of tested vehicle electric equipment by its reality the position on the vehicle is fixed on the plane of chassis ridgepole by support above.
The present invention in working order down, when the piston rod of four hydraulic rams moves back and forth with certain frequency and stroke, chassis ridgepole is made the up-down vibration of all around together with each assembly simulating vehicle road driving bad working environments of the vehicle electric element equipment on it, thereby detects the functional reliability and the durability of test vehicle electric equipment.
The present invention has substantive distinguishing features and marked improvement, because be to the chassis ridgepole of vehicle and on each assembly vibration test of electric equipment, rather than also need not comprising weigh tens tons heavy-duty vehicle car load body vibration test such as driving engine and compartment, therefore test cell can either produce tens of thousand Ns of above vibrational loadings and be unlikely too huge again, can adopt less actuating device; Each assembly of tested vehicle electric equipment is fixed on this arrangement on the chassis ridgepole by it at the actual position on the vehicle, and the piston rod of four hydraulic rams moves back and forth frequency and stroke can change according to test requirements document, make the state more realistic vibration operating mode of tested vehicle electric equipment in detecting process of the test, simulation is near road operation test; Because test condition of the present invention can be controlled, can strengthen vibrational load, therefore shorten the test period greatly, the comparability of experimental investigation, repeatability, good economy performance, thus the reliability of heavy duty truck and other heavy-duty vehicle electric equipment, the problem that durability originally can't detect test solved.That the present invention has is simple in structure, connection and reasonable arrangement, installation are easy to adjust, reliable operation, characteristics that cost is low, is applicable to functional reliability, the durability test of various types of heavy duty trucks and heavy-duty vehicle electric equipment.
