       本期的主角是这台1954年道奇Firearrow?II概念车。它是由维吉尔?艾克斯纳(Virgil?Exner)设计。他是克莱斯勒公司的传奇设计总监。20世纪50年代是汽车设计历史上最重要的十年之一,20世纪许多最令人难忘的汽车都是在这个时期生产出来的。在那个时代,美国人非常钟爱大车,以及大面积的镀铬装饰。

       上世纪50年代中期,维吉尔?艾克斯纳(Virgil?Exner)将克莱斯勒推向了汽车设计的前沿,他"前瞻性"的设计方案让新车造型更加天马行空。

       而Firearrow概念车是他最早的设计之一,它为公司带来了最新的设计风格。据说,艾克斯纳的概念车非常有影响力,以至于福特和通用汽车都从他们那里获得了重要的灵感,并运用到新车上。

       从维吉尔完整的设计报告上,我们能看到很多亮点车型,包括1953年克莱斯勒敞篷跑车,Studebaker(斯蒂旁克)?Champion、Plymouth?(普利茅斯)Belvedere、Dodge?(道奇)Coronet,DeSoto?(德索托)Adventurer、Plymouth?Fury、Studebaker?Starlight、Chrysler?(克莱斯勒)C-300等。

       外观上,道奇Firearrow?II概念车为未来的车型奠定了基础。优雅的车身设计和喷气式飞机的前端加上无框挡风玻璃和一个可折叠的车顶。这些都都非常有特点。前脸突出的进气格栅以及车身两侧,都采用了大量的镀铬装饰。甚至灯组和排气周围也有很多镀铬装饰。

       内饰上,Firearrow?II为两人乘坐车型,为营造舒适的内饰,车内提供了丰富的配置,包括扶手,烟灰缸,厚实的座椅靠垫和充足的腿部空间。

       动力上,该车搭载Ram?Hemi?V8发动机,这个体积241立方英寸(4.0L)的发动机,可产生150马力,并通过4速自动变速器将动力传递至后轮。

       底盘上,Firearrow?II采用119英寸的标准底盘,大大简化了开发过程,这使得该车的维护保养变得轻松很多。

       当艾克斯纳的设计完成后,意大利的Ghia负责制造了Firearrow?II的车身,之后将成品寄了回去。这款车是四款车型之一,第一款车只是一个用来展示模型,第二款车已经可以上路使用,第三款车是轿跑版,最后一款是量产版。

       1954年,道奇公司生产的概念车Firearrow?II在美国车展展出后,就被封存。现在,它依然保持着原来的样子。

       Mecum现在正在出售这辆车,并不是以拍卖的形式,而是作为常规销售,如果你对它感兴趣,不妨看看它。

射箭的那个靶用术语怎么说

       4.3 General control of cross-ring

       4.3.1 passage space design

       1. Import Road Layout The purpose of the implementation of signal control is to enable different traffic flows, the separation in time. In order to facilitate the implementation of signal control, it is necessary to import Road lane divided function (see Figure 4), enables the flow of traffic各行其道to avoid mutual interference.

       2. Central Road layout

       Different flows in order to avoid causing traffic chaos intertwined, Central Road improve traffic capacity, as well as with the import function to match the Road driveway, it is necessary to Ring Road also divided roadway function, is mainly divided into lanes to turn left and go straight ahead (see Figure 4). Ring Road that is at least has a straight, a left turn lane.

       4.3.2 Determination of signal phase

       Because of the role of Bay Road, the traffic to turn left and straight on to the conflict between traffic can actually evolve into a degree of interwoven, the result of the implementation of four-way ring to pay the general control, to be used in the form of two-phase control; more Road Central, submitted by the specific circumstances of the case to determine visibility.

       4.3.3 signal configuration and priority rules

       1. Signal configuration based on the above analysis, the arrow lights should be configured in order to facilitate the flow of different traffic with different traffic signal.

       2. Priority rule ring along with the phase because of the existence of different traffic flows, the left turn traffic flow and traffic flow straight to the potential for conflict exists between, it was necessary to set the priority rules, usually in the same phase, the straight traffic stream have precedence in the left turn traffic flow (also visible on the actual situation).

       4.3.4 Signal Timing

       Ring Road divided roadway function and implementation of signal control can be used to eliminate cross-Ring Road in the loop-cutting issues, thus the control method in the signal control principle with the general level-crossing control method is similar to Webster-based allocation method to determine when the timing program, and depending on the actual coordinate the flow of traffic than the actual green time. However, due to the Central Road, vehicles traveling the speed limit and driving distance is longer, according to the practice of using yellow light time of 3s may lead to the end of yellow line to turn left through the parking of vehicles with another phase of the early exit of vehicles (cars to turn left or go straight vehicles) in the Bay Road entrance of intertwined or conflicts, which have a need to re-determine the time between green and yellow light duration.

       Located around the island radius r0, Ring Road, the width of each lane w, calculated traveling speed v0, the driver reaction time t0, then import Road vehicles from passing through the most lateral straight junctions adjacent most lateral point of conflict is about the shortest distance

       (17)

       So (two-phase case) the Green interval I for

       (18)

       By type (13) yellow light time can be identified.

       5 Ways to control the application of the conditions of analysis

       1. Flow conditions are usually, non-signal-controlled roundabout capacity value of the experience of 2 000pcu / h or so, so when the actual traffic demand roundabout approach or exceed the value of this experience that it is necessary to the implementation of signal control is proposed in this paper The three kinds of control mode, both for flows exceeded 2 000pcu / h and the control signals required to pay in terms of ring. The first two kinds of control method is more applicable to a larger left turn traffic situation.

       2. Intersection turn left two-step control of the geometric conditions of the ring to pay, generally applicable to large diameter around the island, Central Road has enough space for traffic to turn left holding queue of traffic flow; turn left step in the control (not around the island) of the Central settlement, generally applies to smaller diameter around the island, around the island has enough space for laying the traffic lane to turn left into the traffic flow of space, and turn left trochoid truck lanes turning radius should be not less than diversion routes set up in accordance with the minimum requirements turning radius; the implementation of the general control of the ring to pay, the general can not satisfy the above two control methods of the geometric conditions (also unable to broaden the reach of these requirements).

       6 Conclusion

       Roundabout past the implementation of signal control, most of them apply the planar intersection of the control method, it is difficult to effectively adapt to the characteristics of the traffic roundabout, a reasonable solution roundabout traffic problems. In this paper, circular control mode is in the roundabout traffic characteristics and traffic problems in an in-depth study based on, and around the island for different scale, different intersections of space, give different control modes, the result of ring type intersection signal control and management of the theoretical research and practical applications are of great value. Since the study conditions, none of three kinds of models of non-motor vehicle and pedestrian interference and other possible cases, which have yet to be combined with the actual situation in a variety of further improving the

       豪士科消防车很多人都知道是美国消防车的代表品牌,其所到之处总有超高的回头率。去年的消防展上,豪士科展出了一辆全新款的超高层供水消防车。相比笔者之前见到的豪士科消防车,这辆Arrow?XT高层供水消防车各方面都有所革新。

       外观方面Arrow?XT还是保持了传统的美式消防车造型,采用了美式消防车的方方正正驾驶室。由此判断,该车的驾驶室还是通用的驾驶室,但是Arrow?XT在前脸造型进行了一定程度的优化。

       矩形中网增加了许多弧形的线条,使得该车在刚毅中看起来有些柔顺,给人一种很不一样的感觉。左右两端的灯组上面布置了四个爆闪灯,下面则是远近光灯以及转向灯。灯组还是采用通用化的布置方式,金属外壳加方形独立车灯。保险杠为长条形钢制保险杠,表面进行了抛光处理,右边安装了两个高音喇叭,左边则是报警器。

       保险杠上面覆盖了防滑层,美国消防车上的标准设计。

       右侧车灯特写

       前面板中间的OSHKOSH?LOGO

       采用了三排驾驶室,前面是驾驶舱,后面则是双排驾乘人员舱。这款驾驶室的乘员舱采用了增高设计,上半部分凸起,方便乘员在车舱内部活动。Arrow?XT乘员舱的玻璃采用分段设计,下半部分的玻璃应该和平顶车型可以通用。

       前门下面安装的车型贴。该车采用了豪士科的Arrow?XT底盘,此款底盘在国内属于全新车型。最大的特色就是配备了康明斯的ISX?550马力发动机,在4×2同级别消防车里,550马力的发动机绝对是大马力。毕竟这么大马力的发动机,一般都是配置在8×4的水牛上。与发动机匹配的是艾利逊的5AT自动变速箱,应该是消防车上的标准化配置了。

       车门把手同样使用的是上拉式全金属把手,美式消防车标配。

       合页式车门

       在驾驶室侧面的冲压金属格栅上还可以看到XT的字样

       双后视镜采用了全金属外壳,别看这个后视镜造型简陋,但是价格应该不低,因为后视镜带有电控设计。

       车门内部护板采用了全金属镜面装饰,各种配件都比较简单,美式消防车的标准风格。之所以采用这么多金属件也是为了防火,让人感觉这消防车用料充实。

       由于无法进入驾驶室内饰,只能打开车门拍摄一张照片。大体上还是采用了豪士科的布置形式,全平面仪表盘,独立机械仪表,这些已经在美国卡车上较为普遍了。但是方向盘造型变化还是挺大的,笔者以前接触过的豪士科消防车大多采用的是三幅式金属方向盘,而这辆车使用了四副式的塑料外壳方向盘。

       上图是肯沃斯卡车内饰,这辆豪士科Arrow?XT底盘使用的就是上图中这款方向盘,只是缺少了多功能按钮。应该是豪士科为了缩减成本采购了一批这样的方向盘,但是看上去确实很别扭。

       座椅是皮尔斯制?

       驾驶舱内部的中央空调

       后半部分的乘员舱采用交错式双排设计形式,一共可以容纳五名成员。

       前桥采用了免维护轮端

       底盘方面该车搭载了固特异的12R22.5轮胎,轮圈则使用了美式对称两孔钢圈,并且喷涂上了红色的喷漆,个人觉得这样比那种银色装饰罩的轮圈好看很多。前后车轮的轮眉均粘贴了金属镀铬装饰条,非常漂亮。

       后轮和前轮的配置基本上相同,只是轮胎由固特异的G289改成了G622。从花纹上就可以很清晰的看出,前轮采用的是注重横向抓地力的转向轮,后轮则是驱动能力较强的块状花纹轮胎。

       车身左侧的控制面板

       上图中的这个面板,应该是超越了底盘技术的一整套独立技术。这辆豪士科Arrow?XT是辆高层供水车,其采用了WaterousCMU/CGV的消防三级水泵。根据笔者查询资料发现,这款水泵也是随着这个Arrow?XT车型首次出现在国内。该水泵的最大流量可以达到每分钟5600L,最大供水高度可以达到420米。

       车身右侧的控制面板

       相比左侧的控制面板,右侧设置的功能就比较少。主要安装了一个驾驶室举升机构,其他的都是比较基本的阀门等部件。

       车载HUSKY?12泡沫系统说明面板,该系统最大流量可以达到每分钟5660L,泡沫罐容积只有189L,使用过程中应该需要额外的后勤车辆进行泡沫供给。此外该车还配备了Akron的3482水炮,每分钟流量4800L,水罐容量为3780L。喷射水的时候最大射程可以达到90米,泡沫则为70米。

       整车的尺寸大约为9200×2500×3200mm,最大整备质量不到20吨,配备了一台550马力的康明斯ISX发动机,我想这也是这辆消防车最特殊的地方。550马力折算一下也差不多有404kW的功率,比功率20kW/t,已经大于机场消防车要求的比功率标准了,加速推背感肯定很强。

       美式消防车因其实用性和威猛著称,而如今全新的550马力Arrow?XT?4×2高层供水消防车的出现,更是让人刮目相看。4×2美式消防车不再限于康明斯ISL?9L发动机,开始往ISX?15L的时代靠拢,届时跑的飞快应该也会是美式消防车的代言词了。
