The LED viewing angle refers to the angle at which we view a sign. When we
look at an LED straight on, it is at full brightness. As we view the LED
from different directions, the brightness changes. This is typical for all
LED signs, but some have a wider viewing angle, allowing we to see more of
the image |

V***b 发帖数: 3419 | 17 toe in 的目的是减小后胎slip angle, 从而增加出弯的稳定性,高速过弯作用尤其明
显。带来的缺点是转弯半径会增大,后胎slip angle减小,understeering多一些。
toe out 相反,可以加快入弯角度,减小转弯半径,增加后胎slip angle,增加
overstering. (我这里说的都是RWD或者AWD啊)
一个车的后轮是调教成toe in还是toe out主要是看这个车干什么用和这个车的其他参
数。经常上赛道的车通常是入弯踩刹车出弯踩油门,toe in会增加一点转弯半径,但不
会带来过多的understeering,但出弯的稳定性大大增加,踩油门的时机也可以提前,
踩油门深度加大。总体上是受益的。
3系这种讲究操控的菜车,toe in就没必要了。因为过弯速度不会太快,入弯也不见得
踩刹车,所以toe in带来的更大的转弯半径和更多的understeering就比较明显了。
最理想的后轮调校是入弯toe out, 出弯toe in, GT-R (R34) 的HICAS系统就是这种,

i****x 发帖数: 17565 | 18 我花了不少时间自己去理解机械限滑的原理,看了不少youtube视频,最后才明白其实
根本就在于摩擦力。这个东西看视频是看不懂的,因为视频只能显示运动方式,但没法
显示摩擦力的大小和方向。
机械限滑的本质就在于要设计一个用A转B能转动(比如过弯时转速差),但B转A则转不
动(比如一个轮子load减小)的装置。worm drive就是这么个东西。大家不妨看看wiki
上关于worm drive的传力方向的介绍。最后一句话很informative。如果斜角正切值小
于摩擦系数,那么就意味着用B转A时,推动A转动的力的分量(=压力x斜角正切值)永
远没有阻止A转动的摩擦力(=压力x摩擦系数)大,所以B就推不动A。

contact reel 和steering column组成的。contact reel 是一个类似于磁带一样的东

的位置。拆方向盘的时候需要注意把它固定住,不然他转回去了,你再转方向盘就会把
内部的线给拔断。steering angle sensor 是给traction control 系统用的。一般拆
方向盘都需要拆airbag,一定要按照车厂的步骤执行,不小心激发可是会要命的。。

s*****8 发帖数: 606 | 20 有个事一直想不明白,来请教一下。假如车是前置后驱,想减少understeer,所以就要
增加后轮的slip angle,举几个例子
1-重心后移,这个很好理解,增加后面的压力来增加slip angle
2-后悬挂调硬,过弯的时候如果悬挂越软,外侧的轮子的受力就越大,如果将悬挂调硬
,两侧的受力分布会更平均所以外侧轮的受力会减小,因此后轮slip angle就会减小,
那么为什么还会导致oversteer呢???
3-降低后轮胎压和用窄胎也可以减少understeer,但减少胎压增大接触面积不是跟用窄
胎相违背么??而且autox的时候我问过好几个老油条,他们都说是增加后轮胎压来减
少understeer,谁能帮忙解释下这个??难道induce和cause oversteer不是一个意思
? |
|
u******w 发帖数: 1882 | 21 这个是是对轮胎特性的误解。understeering和over在本质上的定义是比较前后轮的
slip angle,而slip angle是只要有侧向里就会发生的,不一定用等到侧滑,因为轮胎
不是刚体。也就是说比如车在前进时哪怕你用人力在侧面推一下车,前后轮都会产生侧
偏角(slip angle),只不过很小。而转弯时就相当于有个侧向力作用,这个时候前后
轮的侧偏角差别决定了整车是过度还是不足转向。
当重心后移时,转弯时相当于后轮受到的侧向力变大,所以后轮的侧偏角变大,整车更
趋于过多转向。
如果你真有兴趣,建议看看《汽车理论》,其实就是汽车动力学,国内车辆专业的必修
课,里面有我说的那个公式 |
