Problems solved by technology

[0003] The fatigue test of the steering bridge is to assess the strength of each component when the steering bridge turns in situ. The fixed position of the test tooling is at the bridge body. For the actual working condition of the bridge body swinging, when designing the test tooling, the bridge body should also be designed. The body has a certain swing space, otherwise the stress of the entire steering axle does not conform to the working conditions of the whole vehicle, which will affect the effect of the fatigue test;

Embodiment

[0030] See figure 1 , a floating steering bridge test tool, including a test base 1 and a steering bridge installation mechanism, a test support 2 is horizontally arranged on the test base 1, and pressure sensing mechanisms are respectively provided at both ends of the test support 2, each pressure sensor The sensing mechanism includes a pressure sensor 31 and a sensor mounting bracket 32, and the pressure sensor 31 is fixedly installed on the upper end of the sensor mounting bracket 32 ​​through a sensor mounting plate 33;

[0031] The steering bridge mounting mechanism includes a horizontal upper pressing plate 41, a slide rail mechanism and a horizontal bridge body mounting plate 45. The upper pressing plate 41 is dynamically arranged on the bridge body mounting plate 45 through the sliding rail mechanism. The two ends of the upper pressing plate 41 are respectively The pressing bolt 6 is correspondingly pressed on the pressure sensor 31 .

[0032] See Figure 4 Each of t...

Abstract

The invention belongs to the technical field of engineering machinery tests, and particularly relates to a steering axle test tool. The test tool comprises a test base and a steering axle installation mechanism, a test support is horizontally arranged on the test base, pressure sensing mechanisms are arranged at the two ends of the test support respectively, each pressure sensing mechanism comprises a pressure sensor and a sensor installation support, and the pressure sensor is fixedly installed at the upper end of the sensor installation support through a sensor installation plate; the steering axle installation mechanism comprises a horizontal upper pressing plate, a sliding rail mechanism and a horizontal axle body mounting plate, the upper pressing plate is movably arranged on the axle body mounting plate through the sliding rail mechanism, and the two ends of the upper pressing plate are correspondingly pressed on the pressure sensors through the cooperation of horizontal positioning plates and bolts. Therefore, according to the test tool, in the in-situ rotation process of tires, the steering axle body has a certain swing space, and meanwhile, the strength can bear external force generated at the steering axle body when the tires run, so that the steering axle body cannot be damaged in a fatigue test.

Description

technical field [0001] The invention belongs to the technical field of construction machinery tests, and in particular relates to a steering axle test tool. Background technique [0002] The steering bridge is the actuator for the steering action of the forklift. The bridge body is the connecting part between the steering bridge and the forklift frame. Due to the special structure of the steering bridge, the bridge body will swing slightly when turning in situ; [0003] The fatigue test of the steering bridge is to assess the strength of each component when the steering bridge turns in situ. The fixed position of the test tooling is at the bridge body. For the actual working condition of the bridge body swinging, when designing the test tooling, the bridge body should also be designed. The body has a certain swing space, otherwise the stress of the entire steering axle does not conform to the working conditions of the whole vehicle, which will affect the effect of the fatigu...
