新手租车如何选择合适车型汽车租赁

 

  1、汽车越(yue)重越(yue)费油

  从节(jie)油观点来看,汽(qi)(qi)车(che)自(zi)(zi)重(zhong)与油耗(hao)成正比关系(xi),即重(zhong)量越大的(de)汽(qi)(qi)车(che)越耗(hao)油,使用经济性相对较差。小(xiao)型车(che)自(zi)(zi)重(zhong)每增加40公斤要多耗(hao)燃油1%。但自(zi)(zi)重(zhong)大的(de)汽(qi)(qi)车(che)具(ju)备急(ji)转弯和急(ji)刹车(che)状况(kuang)下稳定性较好的(de)优点。

  2、不同驱动(dong)方式(shi)的利弊

   根据动(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)传(chuan)(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)(shi),汽(qi)车(che)(che)可(ke)分(fen)为“四(si)轮(lun)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)”,“发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)前(qian)(qian)置(zhi)(zhi)(zhi)、后(hou)(hou)(hou)桥(qiao)(qiao)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)”,“发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)前(qian)(qian)置(zhi)(zhi)(zhi)、前(qian)(qian)桥(qiao)(qiao)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)”,“发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)后(hou)(hou)(hou)置(zhi)(zhi)(zhi)、后(hou)(hou)(hou)桥(qiao)(qiao)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)”四(si)种: 四(si)轮(lun)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)(zhu)要用(yong)在(zai)(zai)(zai)一(yi)些(xie)越(yue)(yue)野车(che)(che)上(shang)(shang),优(you)点使(shi)(shi)前(qian)(qian)后(hou)(hou)(hou)轮(lun)都有驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li),牵(qian)引(yin)(yin)(yin)力(li)(li)大(da)(da),通过性(xing)强,附(fu)着(zhe)力(li)(li)大(da)(da),稳(wen)定性(xing)好,车(che)(che)身和传(chuan)(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)系统(tong)的(de)钢板比轿(jiao)车(che)(che)厚、 安全系数高,适(shi)于越(yue)(yue)野。但缺(que)点是(shi)重(zhong)(zhong)量(liang)大(da)(da),节(jie)油(you)性(xing)差。 发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)前(qian)(qian)置(zhi)(zhi)(zhi)、后(hou)(hou)(hou)桥(qiao)(qiao)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)(zhu)要用(yong)在(zai)(zai)(zai)一(yi)些(xie)中、高级轿(jiao)车(che)(che)上(shang)(shang),优(you)点是(shi)前(qian)(qian)后(hou)(hou)(hou)桥(qiao)(qiao)承载的(de)负荷基本一(yi)样,动(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)性(xing)强,牵(qian)引(yin)(yin)(yin)力(li)(li)大(da)(da),在(zai)(zai)(zai)爬坡、泥泞道路(lu)和颠簸路(lu)上(shang)(shang)行驶时,动(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)性(xing)、防后(hou)(hou)(hou)轮(lun)侧(ce)(ce)滑(hua)(hua)和稳(wen)定性(xing)明(ming)显优(you)越(yue)(yue)于“前(qian)(qian)置(zhi)(zhi)(zhi)前(qian)(qian)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)”的(de)汽(qi)车(che)(che)。但其缺(que)点是(shi)传(chuan)(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)轴(zhou)退至后(hou)(hou)(hou)桥(qiao)(qiao),导(dao)致(zhi)地(di)板凸起(qi),几个总(zong)成分(fen)开布置(zhi)(zhi)(zhi),占据空间较(jiao)大(da)(da),很难使(shi)(shi)汽(qi)车(che)(che)小(xiao)(xiao)型化。 发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)前(qian)(qian)置(zhi)(zhi)(zhi)、前(qian)(qian)桥(qiao)(qiao)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)(zhu)要用(yong)在(zai)(zai)(zai)中小(xiao)(xiao)型汽(qi)车(che)(che)上(shang)(shang),优(you)点是(shi)省了传(chuan)(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)轴(zhou),地(di)板平坦(tan),传(chuan)(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)系紧凑(cou),重(zhong)(zhong)量(liang)减轻,地(di)板降低,重(zhong)(zhong)心下(xia)降。但其缺(que)点是(shi)上(shang)(shang)坡时重(zhong)(zhong)量(liang)向后(hou)(hou)(hou)移(yi),前(qian)(qian)桥(qiao)(qiao)负荷减轻,不(bu)(bu)能产(chan)生(sheng)(sheng)足够的(de)牵(qian)引(yin)(yin)(yin)力(li)(li),在(zai)(zai)(zai)较(jiao)滑(hua)(hua)的(de)路(lu)面上(shang)(shang)因前(qian)(qian)桥(qiao)(qiao)重(zhong)(zhong)量(liang)不(bu)(bu)够而产(chan)生(sheng)(sheng)不(bu)(bu)了足够的(de)牵(qian)引(yin)(yin)(yin)力(li)(li);下(xia)坡时前(qian)(qian)桥(qiao)(qiao)负荷过重(zhong)(zhong),特别是(shi)在(zai)(zai)(zai)下(xia)坡刹车(che)(che)时前(qian)(qian)桥(qiao)(qiao)负荷会(hui)进一(yi)步加重(zhong)(zhong)。这(zhei)种车(che)(che)型不(bu)(bu)宜在(zai)(zai)(zai)上(shang)(shang)下(xia)坡较(jiao)多的(de)山区使(shi)(shi)用(yong)。 发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)后(hou)(hou)(hou)置(zhi)(zhi)(zhi)、后(hou)(hou)(hou)桥(qiao)(qiao)驱(qu)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)(shi)主(zhu)(zhu)要用(yong)在(zai)(zai)(zai)微型车(che)(che)上(shang)(shang),优(you)点是(shi)省了传(chuan)(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)(dong)轴(zhou),附(fu)着(zhe)力(li)(li)大(da)(da),牵(qian)引(yin)(yin)(yin)力(li)(li)也大(da)(da),轴(zhou)距较(jiao)小(xiao)(xiao),地(di)板下(xia)没有排气管,发动(dong)(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)废气、噪(zao)音(yin)不(bu)(bu)会(hui)污(wu)染车(che)(che)厢内。但其缺(que)点是(shi)后(hou)(hou)(hou)桥(qiao)(qiao)负荷大(da)(da),转弯易侧(ce)(ce)滑(hua)(hua),操纵系统(tong)太长,结构(gou)复(fu)杂,冷却系统(tong)复(fu)杂,行李箱太小(xiao)(xiao)。

  3、自动档汽车省事不省钱(qian)

  自动(dong)(dong)档(又称自动(dong)(dong)变(bian)速)装备有自动(dong)(dong)控(kong)制装置,行车中(zhong)可(ke)根据(ju)车速自动(dong)(dong)调整档位,无(wu)需人工操作(zuo)(zuo),省去(qu)了许多换档及踏踩离合的(de)工作(zuo)(zuo)。其(qi)不足之处(chu)在于(yu)价格(ge)昂(ang)贵、维修费(fei)用很高,而且使用起来(lai)比手动(dong)(dong)档车费(fei)油,因为(wei)自动(dong)(dong)变(bian)速器的(de)动(dong)(dong)力传递(di)是通过(guo)液压来(lai)完(wan)成(cheng)的(de),在工作(zuo)(zuo)中(zhong)会造(zao)成(cheng)动(dong)(dong)力损失。尤其(qi)是低速行驶或堵车中(zhong)走走停(ting)停(ting)时,更会增(zeng)大油耗。

  4、选(xuan)用(yong)装配子午线轮(lun)胎(tai)的汽(qi)车(che)

  装有子午线轮胎的汽车与装有斜交轮胎的汽车相比,耐磨性可以提高50%~100%,滚动阻力降低20%~30%,而且(qie)可以节油6%~8%。

  5、选用铝台金轮圈的汽(qi)车(che)

  目前铝合金轮圈(quan)的价格(ge)仍是钢(gang)制(zhi)轮圈(quan)的2~3倍左右,但其使(shi)用(yong)的效益也(ye)远高于(yu)钢(gang)轮:

(1)质量轻,省油(you);

(2)散(san)热性能好,增(zeng)加轮胎寿命(ming);

(3)真(zhen)圆度高,可以提高车轮运动精(jing)度,适合(he)高速行驶;

(4)弹性(xing)好,提高车辆行(xing)驶中的平顺性(xing),更易于吸收运动中的振动和噪音;

(5)可100%回(hui)收,属环(huan)保产品(pin)。
