Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as Figure 1-Figure 2 Shown are the overall effect diagram of the multi-axle vehicle steering test bench and axle and the exploded view of each module of the test bench respectively in the present invention. In this embodiment, an experimental bench for testing the steering performance of a multi-axle vehicle mainly includes a supporting base module A, a power-assisted telescopic guiding module B, a road surface simulation module C, a steering bridge simulation loading module D, and a main frame module E. ;

[0034] The support base module A is located at the bottom of the test bench, and the power-assisted telescopic guide modules B are arranged on the left and right sides of the support base module A. The road surface simulation module C is connected above each power-assisted telescopic guide module B, and the road surface simulation module C on each sid...

Abstract

The invention discloses an experiment table frame for testing multi-axis vehicle steering performance. The experiment table frame comprises a support frame and an axle fixed on the support frame, wherein the two side ends of the axle are each provided with a tire, one side or two sides of the axle are provided with road simulation plates in contact with the tires, and the lower portions of the road simulation plates are fixedly connected with hydraulic servo cylinders. According to the invention, through accurate control of the hydraulic servo cylinders, the accuracy of the experiment table frame in simulating fluctuation loads and static loads of the tires is guaranteed; through adjusting the mutual position relation between transverse telescoping structures and the stroke lengths of the hydraulic cylinders, the table frame can be applied to simulation of axles with different wheelspan and different heights, and the adaptability of the experiment table frame is effectively improved; and through replacement of road simulation plates made of different materials, the experiment table frame can simulate road features under different work conditions, and the practicality of the experiment table frame is effectively improved.

Description

technical field [0001] The invention discloses an experimental bench for testing the steering performance of a multi-axle vehicle. Background technique [0002] At present, multi-axis steering technology is a key technology in the vehicle industry. Large-scale wheeled vehicles are widely used in infrastructure construction (such as large-tonnage all-terrain cranes, large-scale beam trucks and mining dump trucks and other civilian equipment) and military heavy industry. (such as military special vehicles such as large missile transport vehicles, heavy electronic launch vehicles and traction vehicles). High-performance multi-axis steering can significantly improve the low-speed maneuverability and high-speed handling stability of large wheeled vehicles, and has become a key technology to measure the development level of modern large and heavy-duty vehicles. [0003] In recent years, with the in-depth research of multi-axis steering technology, the vehicle test of experimental...
