雙橫臂式懸掛系統(tǒng)外文文獻(xiàn)翻譯@中英文翻譯@外文翻譯

-1- 附錄 雙 橫臂式懸掛系統(tǒng) 附錄 1 外文中文翻譯 按橫臂數(shù)量的多少又分為雙橫臂式和單橫臂式懸掛系統(tǒng)。單橫臂式具有結(jié)構(gòu)簡(jiǎn)單，側(cè)傾中心高，有較強(qiáng)的抗側(cè)傾能力的優(yōu)點(diǎn)。但隨著現(xiàn)代汽車速度的提高，側(cè)傾中心過(guò)高會(huì)引起車輪跳動(dòng)時(shí)輪距變化大，輪胎磨損加劇，而且在急轉(zhuǎn)彎時(shí)左右車輪垂直力轉(zhuǎn)移過(guò)大，導(dǎo)致后輪外傾增大，減少了后輪側(cè)偏剛度，從而產(chǎn)生高速甩尾的嚴(yán)重工況。單橫臂式獨(dú)立懸掛系統(tǒng)多應(yīng)用在后懸掛系統(tǒng)上，但由于不能適應(yīng)高速行駛的要求，目前應(yīng)用不多。雙橫臂式獨(dú)立懸掛系統(tǒng)按上下橫臂是否等長(zhǎng)，又分為等長(zhǎng)雙橫臂式和不等長(zhǎng)雙橫臂式兩種懸掛 系統(tǒng)。等長(zhǎng)雙橫臂式懸掛系統(tǒng)在車輪上下跳動(dòng)時(shí)，能保持主銷傾角不變，但輪距變化大 (與單橫臂式相類似 )，造成輪胎磨損嚴(yán)重，現(xiàn)已很少用。對(duì)于不等長(zhǎng)雙橫臂式懸掛系統(tǒng)，只要適當(dāng)選擇、優(yōu)化上下橫臂的長(zhǎng)度，并通過(guò)合理的布置、就可以使輪距及前輪定位參數(shù)變化均在可接受的限定范圍內(nèi)，保證汽車具有良好的行駛穩(wěn)定性。目前不等長(zhǎng)雙橫臂式懸掛系統(tǒng)已廣泛應(yīng)用在轎車的前后懸掛系統(tǒng)上，部分運(yùn)動(dòng)型轎車及賽車的后輪也采用這一懸掛系統(tǒng)結(jié)構(gòu)。 雙橫臂式獨(dú)立懸架，是一種車輪在汽車橫向平面內(nèi)擺動(dòng)的獨(dú)立懸架，這種獨(dú)立懸架被廣泛應(yīng)用在轎車前輪上。雙 橫臂，顧名思義，兩條臂橫向布置，兩臂有做成 A 字形或 V 字形， V 形臂的上下 2 個(gè) V 形擺臂以一定的距離，分別安裝在車輪上，另一端安裝在車架上。 雙橫臂式獨(dú)立懸架一般多為不等臂雙橫臂式，上臂比下臂短，當(dāng)汽車車輪上下運(yùn)動(dòng)時(shí)，上臂比下臂運(yùn)動(dòng)弧度小。這將使輪胎上部輕微地內(nèi)外移動(dòng)，而底部影響很小。這種結(jié)構(gòu)有利于減少輪胎磨損，提高汽車行駛平順性和方向穩(wěn)定性。由于當(dāng)雙橫臂式獨(dú)立懸架懸架變形時(shí)，車輪平面將產(chǎn)生傾斜而改變兩側(cè)車輪與路面接觸點(diǎn)的距離 輪距，致使輪胎相對(duì)于地面?zhèn)认蚧?，破壞輪胎和地面的附?。 -2- 附 錄 2 外文文獻(xiàn) Number by the number of arm is divided into wishbone and single -wishbone suspension system. Single-Arm has a simple structure, roll center height, there is a strong anti-roll capability advantages. But with the increased speed of modern cars, the roll center is too high will cause the wheel beats track changes, tire wear increased, and in sharp turns around the wheel vertical force when the transfer is too large, resulting in rear wheel camber increases, reducing the rear wheel cornering stiffness, resulting in a serious condition high-speed flick. Single-wishbone independent suspension system multi-application system in the rear suspension, but can not meet the requirements of high speed, the current application is small. Double wishbone independent suspension system is at the upper and lower arm of equal length, is divided into equal length wishbone and the unequal length double wishbone suspension system of two. Equal length double wishbone suspension system in the wheel up and down when the kingpin inclination to maintain the same, but the track changes in a large (and similar single-Arm), resulting in severe tire wear, is now rarely used. For the unequal length double wishbone suspension system, as long as the appropriate choice to optimize the length of the upper and lower arm, and by a reasonable arrangement to enable track and the front wheel alignment parameters are within acceptable limits to ensure the car have good driving stability. Present unequal length double wishbone suspension system has been widely used in cars, front and rear suspension systems, part of the sports car and the cars rear suspension system is also using this structure. Double wishbone independent suspension, is a horizontal plane in the automotive wheel independent suspension swing, which is widely used independent suspension on the front of the car. Double wishbone, by definition, two-arm horizontal arrangement, the arms are made of A-shaped or V-shaped, V-shaped upper and lower arm of the V-shaped arm 2 to a certain distance, the wheels were installed in the other end installed in the car rack. Double wishbone independent suspension in general are mostly ranging -3- arm double wishbone type, upper arm shorter than the lower arm, the wheel when the car moves up and down, the upper arm under the arm movement than the smaller arc. This will move the tire inside and outside the top slightly, while the bottom has little effect. This structure helps to reduce tire wear, improve vehicle ride comfort and directional stability. Because when the double wishbone independent suspension suspension deformation, tilt wheel plane will have to change the
