V. vibrationwheeldrive motor and reducer vibrationwheeldrive motor, reducer and stand together in front on the frame, gear box output connection on the clubs Board, powered by the motor output shaft to the gear, and then to the plum blossom, plum blossom again to vibrating wheel, driving vibration wheel rotation. VI. vibration support both ends of the eccentric shaft, walking through the vibration of the bearing on the bearing in the housing, vibration motors by supporting ponents supported on the right bearing seat. Vibration bearing Sweden SKF bearing or Germany FAG bearing. Walking support 論文178。 variable piston by electromagic valve with two oblique angle, so that the machine has four speeds, to meet the needs of different operating conditions. III. vibration of hydraulic system of vibratory hydraulic system is made up of single pump Dan Mada closed hydraulic circuit, maximum working pressure of the system is 38MPa. Vibration pump for variable inclined plate piston pump, vibration motor for quantitative inclined axis piston. By manipulating electromagic valve, you can make the vibration of pumps swashplate with opposite two variable oblique angle, so that different direction and flow of high pressure oil pump output, vibration motor with resulting different steering and speed to vibrations at different frequencies and amplitudes vibration. Four steering steering hydraulic system using opencircuit hydraulic system, the system working pressure 16MPa. By steering pump, hydraulic steering gear, two steering cylinders and tubing and other ponents. Steering pump gear pump. Five hydraulic system of hydraulic control system and accessories also include integrated control valve block, collection block, and tanks, filters, coolers, accessories. Hydraulic brake oil of systems at the same time for the braking system provides. 論文178。s standard of vibratory road roller, for highgrade Highway, railway, airport, dam, terminals, a high standard of subgrade engineering paction operations. Compaction of z has a unique ability, max power 56800kg, good paction effect. Z The overall opening of panels, all readily available and maintenance points. Z Centralized, external hydraulic pressure points, making hydraulic systems testing, maintenance more convenient. Z Complete safety protection device, so that operators are fully guaranteed. The second section The overall structure YZ12 type vibration on the roller make use of the wheel of the vibration on the road is pacted, 論文178。 Introductionto YZ12 Vibration roller 論文178。 用 吊車裝卸壓路機(jī)時(shí) ， 必須先將中心鉸接架用固定裝置固定好后 ， 再用大型平板吊鉤起 吊，以保證壓路機(jī)吊起后仍保持平直狀態(tài)。 論文178。 一．運(yùn)輸 不論是采用公路還是鐵路運(yùn)輸，對壓路機(jī)的運(yùn)輸都必須選用具有合適容積和裝載 能力的車輛來進(jìn)行。 第 十三 節(jié) 運(yùn)輸和裝卸安全要求 一般情況下 ， 壓路機(jī)不得長途高速行駛 。因振動(dòng)會(huì)增加向兩邊滑行的危 險(xiǎn)。 z 為避免意外翻車，在斜坡邊工作時(shí)，不要突然轉(zhuǎn)向。 z 夜間行駛和施工應(yīng)開啟前后大燈照明。 z 在地面不夠堅(jiān)實(shí)或有坑穴時(shí)，不得使用本機(jī)。 z 不允許壓路機(jī)在超過其允許爬坡度的坡道上行駛。（注意事項(xiàng)：降下 覆蓋件前必須將軟軸操縱器拉出 。 z 覆蓋件開啟自動(dòng)保護(hù)裝置 ： 當(dāng)覆蓋件在手動(dòng)液壓泵作用下向上開啟時(shí) ， 安全防護(hù) 裝置能防止覆蓋件意外下落 ， 當(dāng)維護(hù)結(jié)束要降下覆蓋件前 ， 將手動(dòng)液壓泵上方的 軟軸操縱器拉出 ， 覆蓋件能在油泵作用下由油缸將之拉下 ， 覆蓋件閉合后將軟軸 操論文178。 z 起動(dòng)閉鎖裝置：當(dāng)壓路機(jī)的行駛操縱桿處于行駛檔位或高低頻選擇開關(guān)不處于 0 位時(shí)不能起動(dòng)發(fā)動(dòng)機(jī)。 第十 一 節(jié) 安全保護(hù)裝置 YZ12 型振動(dòng)壓路機(jī)有完備的安 全裝置 z 設(shè)有防滾翻保護(hù)裝置（ ROPS）。 系統(tǒng)電壓 24V，負(fù)極搭鐵，線路采用單線制。 第十節(jié) 電氣系統(tǒng) 電氣系統(tǒng)包括蓄電池、直流起動(dòng)電動(dòng)機(jī)、三相交流發(fā)電機(jī)、照明燈具以及電氣儀表、 監(jiān)控儀表 、 安全保護(hù)元件 、 聲光報(bào)警裝置等 。 司機(jī)座椅高度可以升降 、 前后可以移動(dòng) 、 靠背角 度也可調(diào)整 。 第 九 節(jié) 駕駛室及操縱系統(tǒng) 駕駛室采用全密封減振式結(jié)構(gòu)，安裝有冷暖 空 調(diào)，操作舒適可靠，外形美觀大方威 武雄壯 ， 內(nèi)飾高雅明亮 ， 達(dá)到國內(nèi)先進(jìn)水平 。 ， 這樣壓路機(jī)可以在不平整的路面 上穩(wěn)定行駛并進(jìn)行壓實(shí)工作。譯文 7 之間允許橫向相對擺動(dòng) ， 擺動(dòng)角不大于 177。 通過控制轉(zhuǎn)向油缸的伸出長度來控制轉(zhuǎn)向角 。 三．中心鉸接架 中心鉸接架由鉸接架 、 軸端擋板 、 球形軸承等組成 。
