摘 要
隨著我國交通運輸業(yè)的迅猛發(fā)展，建設(shè)項目的增多，雙前軸轉(zhuǎn)向汽車的使用越來越普遍。而車輪側(cè)滑引起輪胎異常磨損是雙前轉(zhuǎn)向汽車普遍存在的問題，因此通過檢測車輪側(cè)滑量的大小可以間接評價輪胎磨損。雙前軸轉(zhuǎn)向汽車車輪側(cè)滑檢測包括輪間和軸間側(cè)滑檢測。為了達到準(zhǔn)確、快速、自動化檢測的目的，本文探討了一種新的檢測方法。這種檢測方法可直接檢測出輪間和軸間側(cè)滑量，其機械系統(tǒng)建立在原有雙板聯(lián)動式側(cè)滑臺的基礎(chǔ)上，通過增加等搖臂軸平移機構(gòu)，加裝兩支位移傳感器。通過對輪間-軸間側(cè)滑檢測系統(tǒng)進行了詳細(xì)的研究和設(shè)計，目的是實現(xiàn)對輪間側(cè)滑量和軸間側(cè)滑量的一體化檢測。本設(shè)計主要是輪間－軸間側(cè)滑臺機械組成部分，包括框架、滑板裝置、等搖臂杠桿機構(gòu)、等搖臂軸平移機構(gòu)、鎖定裝置等。

ABSTRACT
With rapidly developing of traffic and transport as well as rising of constructing item in our country, the number of double-front-axle steering automobile is also increasing.But the unusual tyre abrasion by wheel sideslip is the most prominent prolem about double-front-axle steering automobile,so by detection of wheel sideslip can estimate the tyre abrasion. Detection of double-front-axle steering automobile’s wheel sideslip includes detection of sideslip between wheels and detection of sideslip between axles. The paper discusses a new detection method which achieves aim of accurate and fast detection.
The detection method which bases on double-board- linkage sideslip tester by adding a equal-rocker-axle shift machine and two lining sensors can detect sideslip between wheels and sideslip between axles directly. By researching and designing detection system of wheel sideslip in detail, aim of which is to realize integrative detection for sideslip between wheels and sideslip between axles. Designation of mechanism involves frame, release device,slip-board device, equal-rocker-leverage machine, equal-rocker-axle shift machine,
comeback device, oriented device, locked device and so on.
Keywords: double-front-axle steering ; wheel location ; wheel sideslip ; sideslip between wheels ; sideslip between axles
