Abstract

An axle housing double-side perpendicular independent loading test device belongs to a heavy drive axle housing loading test device and comprises an actuator gantry support, a spherical hinge, hydraulic actuators, a force sensor, rolling bearings, bases and an axle housing. The bases are respectively connected to two ends of the bottom of the actuator gantry support, the rolling bearings are connected onto the bases, and the two actuators are connected to the upper end of the actuator gantry support. The test device has the advantages that the test device leads an axle housing test to be simple in structure, the spherical hinge guarantee precision of loading force, the rolling bearings lead the axle housing to be closer to an actual working condition, the two actuator independently controlling load can more effectively stimulate the actual working condition that different forces are generated on two sides of the axle housing caused by inconsistent road surface on two sides, the action forces generated are closer to the actual working condition, the test device can perform fatigue resistance test on the axle housing by perpendicularly and independently loading the two sides of the axle housing, and realize application of unbalanced loading, and obtained test results can reflect actual performance of the drive axle housing.

Description

The vertical independent loads test unit of axle housing bilateral
Technical field
The utility model relates to a kind of Heavy-Duty Drive-Axle axle housing load testing machine, the vertical independent loads test unit of particularly a kind of axle housing bilateral.
Background technology
At present, when people carry out the vertical load test to heavy driving axle housing, generally all be to use Heavy-Duty Drive-Axle shell vertical load stand that heavy driving axle housing is tested, this Heavy-Duty Drive-Axle shell vertical load stand has portal frame, hydraulic actuator and chevron shaped support are arranged in portal frame, chevron shaped stent support is carried out load test at the axle housing bilateral to axle housing, described hydraulic actuator is single actuator, by chevron shaped support axle housing is loaded, this load mode is identical in the axle housing both sides, and the shortcoming of this mode is effectively to simulate axle housing both sides load step inequality and the inconsistent operating mode of magnitude of load.
The utility model content
The purpose of this utility model is to provide a kind of: the vertical independent loads test unit of axle housing bilateral in the time of effectively simulating axle housing both sides load operating mode inequality
The purpose of this utility model is achieved in that this load testing machine comprises actuator gantry support, ball pivot, hydraulic actuator, force transducer, rolling bearing, base and axle housing, two ends in actuator gantry support bottom respectively connect a base, are connected with rolling bearing on base; Be connected with two actuator in the upper end of actuator gantry support.
Described hydraulic actuator comprises ball pivot, actuator and force transducer, is linked in sequence from the top down; Described rolling bearing comprises semicircular body and right cylinder, on right cylinder, have one with semicircular body corresponding recessed, semicircular body is positioned at recessed.
Beneficial effect: owing to adopted above-mentioned test unit, axle housing is placed on above the base of two ends by two rolling bearings, makes axle housing keep floating property in process of the test; Two independent imposed loads of actuator difference, also can unite and apply same load in groups jointly, can simulate various vertical load operating mode or operating mode combination that axle housing runs in practical work process, also can the load that actual condition collects be applied to above the axle housing by actuator system, promptly realize load reproduction process.Can effectively simulate axle housing both sides load operating mode inequality, reach the purpose of this utility model.
Advantage: the utility model makes the axle housing test structure simple, and ball pivot guarantees the precision of loading force, and rolling bearing more approaches actual condition by axle housing; Two independent control loads of actuator, can simulate effectively more that the road surface, both sides is inconsistent advances to produce power actual condition inequality in the axle housing both sides, the acting force that produces more approaches actual condition, can the vertical independent loads of bilateral carry out the endurance test to axle housing, realizes applying of unbalance loading load.The test findings that obtains can reflect the actual performance of drive axle axle housing.
