低速載貨汽車離合器的設(shè)計
摘要：離合器依靠其主、從動部分的摩擦來傳遞動力且能分離的機(jī)構(gòu)。YC1040低速載貨汽車中針對多數(shù)摩擦離合器存在散熱能力不足，摩擦片易磨損等缺點的現(xiàn)狀，根據(jù)生產(chǎn)的實際情況和需要，依據(jù)經(jīng)濟(jì)、可靠、操作方便的原則，采用單片干式摩擦離合器，為保證其技術(shù)先進(jìn)性和經(jīng)濟(jì)合理性，還采取了以下措施：（1）為使離合器保證結(jié)構(gòu)簡單，尺寸緊湊，散熱良好，維修調(diào)整方便，從動部分轉(zhuǎn)動慣量小，在使用時能保證分離徹底、接合平順，選擇采用單片盤摩擦片。（2）為保證結(jié)構(gòu)簡單、制造容易，保證結(jié)構(gòu)簡單，制造方便，考慮壓緊彈簧的結(jié)構(gòu)形式選用周置彈簧，壓緊彈簧采用圓柱螺旋彈簧。（3）壓盤的驅(qū)動方式選用凸塊-窗孔式，采用3個分離杠桿，且分離杠桿保證足夠的剛度，使其工作可靠。（4）分離軸承選用開式的推力球軸承，改進(jìn)潤滑措施后，解決了這類軸承潤滑條件差、磨損嚴(yán)重、噪聲大、可靠性差、使用壽命低等缺點，在保證工作可靠的條件下降低制造成本。
通過本設(shè)計使其具有從動部分轉(zhuǎn)動慣量小、散熱性好、結(jié)構(gòu)簡單、調(diào)整方便、尺寸緊湊、分離徹底等優(yōu)點，而且在結(jié)構(gòu)上采取一定的措施，能使其結(jié)合平順。

Design of the Clutch of the Low-speed Truck
Abstract: Depending upon the friction, clutch is a mechanism to transmit or disengage the power, In view of the shortcomings of present clutch’s insufficient thermal radiation ability is abrasion and according to the actual situation and needs of production and the principle of economical, reliable, easy to operate, The low speed truck YC1040 uses the monolithic dry type friction clutch, to ensure its technical progress and the economical rationality, it also has taken the following measurement : (1) In order to guarantee its simple structure, compact size, good radiates, convenient to adjustment , driven partial rotations inertia small, when use can guarantee the separation thorough, the joint is smooth, chose to uses the single bobbin friction disk.(2) In order to guarantee the structure simple, easy to manufacture, to guarantee structure simple, convenient to manufacture , considered contracts the spring the structural style to select the week to set at the spring, contracts the spring to use the column helical spring. (3) Presses the plate the drive type to select the ridge - window hole type, uses 3 separations release levers, also the separation release lever guarantee enough rigidity, make its work to be reliable.(4) The release bearing selects start -like the thrust force ball bearing, after the improvement of lubrication , seriously solved the bad condition of these bearing lubrication , attrition, big noise, badly reliability , low life etc shortcoming, reduced the cost of production under the conditions that it can guarantee the work to be reliable.
Tthis design can enable many merits which is that its driven partial rotations inertia small, the radiation be better, the structure is simply, convenient to adjustment, the size compact, the separation thorough and so on, moreover it also takes some measure in the structure, which can make its union to be smooth.
