Abstract
The utility model discloses a vehicle steering pull rod durability test device. The device comprises a fixation clamp which is hinged with one end of a steering pull rod and a loading cylinder body with a piston push rod. The device further comprises a rocker arm bracket and a middle rocker arm with one end rotationally assembled on the rocker arm bracket. A hinge structure which is hinged with the other end of the steering pull rod is arranged at the position, which is away from the rocker arm bracket, on the middle rocker arm. The piston push rod of the loading cylinder body is hinged directly or through a force transferring mechanism on the position between the hinge structure on the middle rocker arm and the rocker arm bracket. According to the utility model, load applied by the loading cylinder body passes through the middle rocker arm and then is applied on the steering pull rod; because bending moment caused by the sinking and deflection of a steering pull rod assembly operates on the fixation clamp and the middle rocker arm, the rocker arm bracket plays a role of bending moment isolation in the system; the device is consistent with the working environment of a steering pull rod of a real vehicle, thus on the premise that the loading environment is similar to the real environment, the influence of bending moment on the test system is avoided.

The utility model content
The purpose of this utility model is to provide a kind of moment of flexure of generation that reduces on the impact of pilot system, with the extension device Vehicular turn pull bar durability test device in serviceable life.
For achieving the above object, the utility model adopts following technical scheme: a kind of Vehicular turn pull bar durability test device, comprise for the stationary fixture hinged with steering linkage one end, be used for applying the loading cylinder body with piston push rod of push-pull effort to steering linkage, this device also comprises rocker arm support, one end rotates the intermediate rockers that is assemblied on the rocker arm support, the position away from rocker arm support on the described intermediate rockers is provided with for the articulated structure hinged with the other end of steering linkage, and the piston push rod of loading cylinder body is direct hinged or pass through the force transmission mechanism hinge mounted in the position between articulated structure and rocker arm support on the intermediate rockers.
Described force transmission mechanism comprises transmission rod and is connected in the power sensor of transmission rod one end, and the piston push rod of described loading cylinder body is connected with the power sensor, and the other end and the intermediate rockers of transmission rod are hinged.
Be connected by spherical hinge between power sensor and the piston push rod.
A kind of Vehicular turn pull bar durability test device of the present utility model, steering linkage is fixed between stationary fixture and the intermediate rockers, the load that the loading cylinder body applies is after-applied on steering linkage by intermediate rockers, because the sinking of steering linkage assembly, the Moment that the reasons such as deflection cause is on stationary fixture and intermediate rockers; rocker arm support has played the effect of isolation moment of flexure in system; and this test unit is consistent with the steering linkage working environment of real vehicle; so guaranteeing to avoid moment of flexure on the impact of pilot system under the loading environment prerequisite close with true environment.
Further, load between cylinder body and the power sensor and is connected by ball pivot, in installation, guarantee that the piston push rod axis of loading cylinder body and loading end on same straight line, with the moment of flexure elimination that acts on the power sensor, further protected testing equipment.
