Check our performance and parameters are based mainly on the use of vehicles May be, and must be connected with the transmission, engine, gear pump Or air pressor to match the performance Process is in strict accordance with industry standards, and has been largely determine its The scope of use conditions. Such as dump truck, due to restrictions on its use, onetime Consecutive working hours is not very long, so do not have too much power to choose, it is necessary to Order to check for the work force, and in order to avoid unnecessary waste of resources. And fire trucks, bulk cement truck, cement mixer truck, truck and Special Purpose Vehicle, such as oil, due to the need for a longer period of time of continuous work, it is necessary to choose Greater power to force continuous operation of the access device. At present, have been successfully Check engine development and maintenance of power use and low cost, reliability and Better access to power gradually to replace the clutch, and transmission of Power from a shaft And so on, and bee the first choice for these vehicles. Check our performance parameters include Check power transmission device to match the maximum output torque, speed ratio from edge devices, gymnastics Longitudinal approach, sustainable working hours, working temperature and so on. The performance The choice of parameters the user needs vary according to the requirements of Determined not elaborate. 2 to determine the way from edge Power take off mode devices need to take power in favor of vehicle layout. Take power from the device The car the way from the main power from the flywheel power (that is, directly from the launch Power machine check), check the clutch, and a checkaxis force and power transmission check. Its In transmission, including transmission access and power precheck, and check the rear edge, top Check, and check our side and so on. Power output from a variety of ways, there are Singleoutput, dual output, with output flange, internal and external spline output, a direct link Pump and so on. Manufacturers and users to be modified according to their different needs Choose a different way of taking power from the power device. 3 to determine the size check our interface Power take off installed in different ways, interfaces are not the same size. Check our interface model and engine size and transmission type directly Clearance. Engine and transmission manufacturers of different size and connectivity Check the power open window is not the same, the user must know the selected chassis Engine model, transmission model, condition and match the use of the access edge Parameters, power device manufacturers access to information based on user and Check the matching of Power. As a result of China39。s Special Vehicle, to get our car39。s life force. Changes in shaft power, the larger coefficient on the design of insurance in terms of its impact on the smaller pumps, and power devices for the impact of check is fatal. Automotive Design typically take the largest power output of 30 kW, normally sufficient to meet the needs of transmission and power, but for productdriven pumps should be taken into account the power and speed is directly proportional to the cubic relationship, due to take power transmission device 41 .47 kW design power is much larger than 30 kW, so now39。在此表示深深謝意。同時也感謝幫助過我同學(xué)們。在畢設(shè)設(shè)計過程中,尤其是在校外實習(xí)過程中,我多次麻煩老師,在此表示忠心感謝。 參考文獻[1] 東風(fēng)汽車有限公司商用車公司市場銷售總部.《東風(fēng)商用車車用取力器匯編》[M].湖北石堰:東風(fēng)汽車變速箱有限公司,2006.[2] 東風(fēng)汽車有限公司商用車公司市場銷售總部.《08東風(fēng)國III商用車車用取力器資料匯編》[M]. 湖北石堰:東風(fēng)汽車變速箱有限公司2008.[3] [J].武漢:專用汽車,.[4] [J].武漢:專用汽車,.[5] 成大先.《機械設(shè)計手冊》[M].北京:化學(xué)工業(yè)出版社,1999.[6] [J].四川內(nèi)江市:內(nèi)江科技,.[7] 何明輝.《專用汽車設(shè)計》[M].武漢:武漢大學(xué)出版社,[8] 徐達.《專用汽車工作裝置原理與設(shè)計計算》[M].北京:北京理工大學(xué)出版社,[9] 東風(fēng)汽車有限公司商用車市場銷售總部.《08東風(fēng)國Ⅲ汽車取力器資料匯編》[M]. 湖北石堰:[10] 周明衡.《減速器選用手冊》[M]化學(xué)工業(yè)出版社,[11] 程及士.《減速器和變速器設(shè)計與選用手冊》[M]機械工業(yè)出版社 [12] 張展.《減速器設(shè)計選用手冊》[M][13] 徐圣群《簡明機械加工工藝手冊》[M][14] Hcho W on the Application of Modern Design Method for Automobile Manual Transmission[J].International Journal of Vehicle [15] H.
