  • 枫下家园 / 爱车一族 / 爬坡速度上不去,transmission problem?请专家分析/赐经验。
    1, 坡度约45度,长400m,D挡,油门踩到底也就55km/h,发动机直喘粗气。但高速公路上,轻松加速上110~120km/h.

    2, 车况:94` corrolla,made in canada, automatic,1.6L engine/ 4 cylinders. 无发动机转速表。transmission oil 颜色/油位正常。
    • 兄弟,你要求太高了,45的坡有这个速度还不满意?根据物理学,30度坡的下华力都有重量的一半了,1.6的殷勤总共才能有多大力量?
      • 45度的坡,用d2 or d1吧
    • 45 度坡?!一般的车都很难开不去。1.6 L 排量的 corrolla 能以 55km/hour 的速度开上去?太夸张了吧?上坡的时候用低速挡,不要用 D 挡。小排量的车上坡就是没劲儿,正常。
      • 底速档?用1还是2?
        • 一般来讲用上大坡 D2 比较合适,如果坡度不大,能达到 3 挡的速度就用 D3。 D1 挡用在脱困或者起步都可以。
          • 啥叫脱困,不明白?请再赐教!
            • 用低速挡,当车陷在泥地里的时候可以在低速获得大的扭力。
              • oic, thanks :-)
    • 我的印象里,好象M1A1最大爬坡也只有60度,请军事专家指正

        • 除了速度慢点,价钱贵点,别的还真没的说,谢谢!看来我的记忆退化的还不厉害,迷<兵器>,<舰船>都是高中时的兴趣了.
        • 应该是 60% 坡度 (31度) 吧? 上60 度的坡是不可能的。
      • NO. M1A1 的最大爬坡度是 31 度。
        • Slope: 60 degrees at 4.5 miles (7.24 kilometers) per hour ?下坡?
          • 哪里看到的?
        • 不应该呀!M1A1爬坡还不如烤肉拉!MY GOD,看来我的烤肉值!
          • 2020 的爬坡性能比 Cherokee 还好呢。 其实 45 度的坡 corrolla 是上不去的。
            • 2020是美军下一代主站坦克吗?我的COROLLA感觉动力还行,油门很灵敏.可能是肉车开多了的缘故.门口有个大破,但我不知道多少度,可能15度吧.
              • 呵呵,我说的 2020 是北京吉普公司出的 BJ 2020,很烂,但是比 4X2 的cherokee 强很多。
                • 那是,那是.越豪华的越野越菜!比如BENZ,BMW,ACRUA的越野其实都是假越野.在他们的宣传手册上写的清楚:更注重公路表现.
                  记的原来在国内看过个节目.一群玩越野的人开着象没鞍野马一样的越野做各种表演.
                  • 我刚才说话不严谨,我的意思是 2020 的爬坡能力比 4X2 的 cherokee 强。4X2 的车都不能算越野车,就是看着象。Mercedes 真正的越野车(不是他出的那个 SUV) 还是非常棒的。
                  • 前几周,切诺基家族的几款新车越野测试,在粗纩豪放的落基山,PEI,西北等地开三天,费用每人大约$200,每天开车观光,司机和乘客纪录感受.再有机会,爱车的弟兄们不如一起报名?费用还会便宜一些.
                    • 俺想参加,就怕开快了从山上掉下去,丢了小命.
    • 事先加速
      我每天要上一个大坡,一公里在上坡前猛加速到80以上,上坡轻而易举.如果不幸前面堵上了或者看到警察了,那就喘着上吧.
      • 感觉旧金山最难开,坡度巨大,一个接一个,上坡基本看不见对面来车,下坡象过山车,路边停车手刹大大重要.真佩服在旧金山开手动档的司机.车也磨损快吧?
    • 请蛇行前进
      • LOL,还得小心侧滚发生。
    • sorry,坡度可能30几度,爬同一个坡,别人的1.6L engine,automatic D挡能跑60km/h, 刚买的车,心慌!
      • 新车一般比教肉,开几千公里就好了
        • 1.6的COROLLA不可能是新的,2001COROLLA都是1.8L 130HP了.
      • 别人那1.6是什么车呀?
      • 非常感谢回复.刚买的94corolla,没有维修records,朋友的88,nissan sentra 1.6L D挡爬同一坡,就能跑60~70km/h.
        • 两车是否在同一条件下比较的.初速度不同,结果当然不同了.还有,不同车马力/扭力的输出曲线不一样,有的车,发力猛,比如CIVIC,有的车中后程猛,比如大奔.还有一种级品,起步,中程,后程,控制随心所欲,那是
          我的11路
    • 坡度约45度,长400m ------------------ 你没有搞错吧? 这度数,跟悬崖差不多了.
