Embodiment Construction

[0022] according to Figure 2-7 The specific structure of the present invention will be described in detail. Such as figure 2 and 3 As shown, a multi-axis loading axle assembly durability test bench, the axle assembly support 2 is fixed on the test bench base 3, and the axle assembly mounting frame 1 is fixed on the upper part of the axle assembly support , the loading device fixed on the base of the test bench includes a longitudinal loading device 4 , a vertical loading device 5 and a lateral loading device 6 . There are three axle assembly supports 2, which are arranged opposite to each other. The axle assembly supports have a certain height, and a plurality of mounting holes 7 are arranged on the side wall for fixing the axle assembly mounting frame 1 on the axle assembly support. On the mounting holes 7 on the opposite sides of the three axle assembly supports 2. During the test work, the automobile axle assembly 9 is fixed on the axle assembly installation frame 1 t...

Abstract

The invention provides a multi-axial loading axle assembly endurance test bed. The problem that an axle assembly only can be loaded in the single direction by a traditional axle assembly endurance test table device is solved. The multi-axial loading axle assembly endurance test bed comprises a longitudinal loading device, a perpendicular loading device and a transverse loading device. An axle assembly can be loaded at the same time by the three loading devices. All the loading devices are structurally hinged to piston rod ends of actuators and loading guide components through turning tripods. The directions of acting force of the actuators are ingeniously changed through the hinged turning tripods so that the three axially-arranged actuators can work simultaneously to load a wheel on the axle assembly. The limited base space of a test table is saved and used through the structure, loading tests can be conducted on the axle assembly simultaneously in the multi-axial directions, the stress condition of an axle under the actual traveling work condition of the wheel is simulated, conditions are provided for test detection equipment to detect multi-axial loading stress at the same time, and the test bed is simple in structure, real in simulation and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to an automobile axle assembly test device, in particular to a multi-axial loading axle assembly durability test bench, which is used to simulate the multi-axis of various road conditions on the axle assembly, namely longitudinal, transverse and vertical directions of loading. Background technique [0002] With the development of the automobile industry, the durability test of the automobile axle assembly is particularly important in the automobile manufacturing process. The automobile axle assembly includes the front and rear axle assemblies. Loading tests in three directions of directional force. At present, the domestic self-owned brand automobile manufacturers adopt the single-directional loading method under a single working condition for the loading durability test of the front and rear axle assemblies, such as vertical working condition loading, braking work The test bench used can only load the front and rear axle assembl...
