Abstract

The invention relates to a radial and deflection combined loading bench test tool for a traction bar. The radial and deflection combined loading bench test tool comprises a slide rail counterforce support, wherein the slide rail counterforce support is connected with a linear slide rail; the linear slide rail is connected with a fixed frame; a fixed block is connected to the interior of the fixedframe and connected with a spherical hinge connection block; the spherical hinge connection block is hinged to the traction bar; the traction bar is hinged to a rotary base; a defection tool is connected to the upper part of the rotary base; a deflection actuator spherical hinge B is connected to the left side surface of the deflection tool and hinged to a deflection actuator; the deflection actuator is hinged to a deflection actuator spherical hinge A; the deflection actuator spherical hinge A is connected with an actuator counterforce support A; a radial actuator spherical hinge B is hingedto the right side surface of the fixed frame; the right end of the radial actuator spherical hinge B is connected with a radial actuator; the right end of the radial actuator is hinged to a radial actuator spherical hinge A; and the right side surface of the radial actuator spherical hinge A is connected with an actuator counterforce support B. The radial and deflection combined loading bench testtool for the traction bar has the advantages of reasonable structure, accurate test, high safety and reliability, excellent adaptability and low manufacture cost.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment, and in particular relates to a thrust rod radial plus deflection combined loading bench test fixture. Background technique [0002] In recent years, the market has reported that there are more and more problems such as deformation and fracture of the thrust shaft of the bus, and cracking and crushing of the rubber of the ball joint bushing. And component manufacturers attach great importance to it. In order to prevent unqualified thrust rod products from entering the market, early judgment and effective improvement are the most effective methods. It is still the most direct and convenient in the industry to judge whether the thrust rod assembly is qualified through the thrust rod assembly bench test. , the most effective judgment method. [0003] At present, most of the bench tests of the thrust rod assembly are in the single-item loading stage, but the bench test requires that the ...

Problems solved by technology

[0003] At present, most of the bench tests of the thrust rod assembly are in the single-item loading stage, but the bench test requires that the force state of the thrust rod should be consistent with that of the real vehicle, which requires that the bench test apply radial and deflection forces to the thrust rod assembly at the same time, and ensure that The radial force can only be along the direction of the thrust rod shaft. At present, most test benches use radial actuators. The radial deformation of the thrust rod produces a large bending moment, which will cause great damage to the actuator, and it will be damaged in long-term tests. Bench actuator, and it is difficult to apply deflection force
