摘要
高尔夫球车后桥（驱动桥）作为汽车四大总成之一，它承载着高尔夫球车的满载荷负重及地面经车轮、车架及承载式车身经悬架给予的铅垂力、纵向力、横向力及其力矩，以及冲击载荷；后桥（驱动桥）还传递着传动系中的最大转矩，桥壳还承受着反作用力矩。高尔夫球车驱动桥结构型式和设计参数除对汽车的可靠性与耐久性有重要影响外，也对汽车的行驶性能如动力性、经济性、平顺性、通过性、机动性和操动稳定性等有直接影响。另外，高尔夫球车驱动桥在汽车的各种总成中也是涵盖机械零件、部件、分总成等的品种最多的大总成。例如，驱动桥包含主减速器、差速器、驱动车轮的传动装置（半轴及轮边减速器）、桥壳和各种齿轮。由上述可见，高尔夫球车驱动桥设计涉及的机械零部件及元件的品种极为广泛，对这些零部件、元件及总成的制造也几乎要涉及到所有的现代机械制造工艺。本文参照传统驱动桥的设计方法进行了高尔夫球车驱动桥的设计。本文首先确定主要部件的结构型式和主要设计参数；然后参考类似驱动桥的结构，确定出总体设计方案；最后对一二级主，从动圆柱齿轮，半轴齿轮和全浮式半轴强度进行校核以及对支承轴承进行了寿命校核。
本设计有以下两大难题，一是将发动机输出扭矩通过万向传动轴将动力传递到后轮子上，达到更好的车轮牵引力与转向力的有效发挥，从而提高载重汽车的行驶能力。二是差速器向两边半轴传递动力的同时，允许两边半轴以不同的转速旋转，满足两边车轮尽可能以纯滚动的形式作不等距行驶，减少轮胎与地面的摩擦。
本设计具有以下的优点：由于的是采用二级圆柱斜齿轮主减速器，使得整个后桥 的结构简单，制造工艺简单，从而大大的降低了制造成本。并且，提高了传动的可靠性。
本设计的最大特点是：主减速器是采用传统的圆柱斜齿轮减速器，与其他的齿轮相比，具有工作平稳，噪音和振动小的优点，且经济性好。

Summary
The bridge(drive bridge) is a car after the golf car four greatly always become of a, it loads the capacity load lotus of golf car negative heavy and ground through car wheel, car and loading type carriage through hang the vertical dint that gives, lengthways dint, horizontal dint and its dint Ju, and the impact carries a lotus;The empress bridge(drive bridge) still delivers to spread to move to fasten medium biggest turn Ju, the bridge hull still bears recoil Ju.The golf car drives bridge structure pattern and in addition to having important influence to the credibility and durable of the car, design parameter also to driving of car the function is like motive, economy, going smoothly and pass sex, flexibility and hold to move stability etc. to contain direct influence.Moreover, the golf car drives bridge in the car of various always become in is also that the species that covers machine spare parts, parts and cent to always become etc. is at most greatly total.For example, drive bridge containment, the lord decelerates a machine, bad soon machine, drive felloe to spread to move device(half stalk and round side decelerate machine), bridge hull and various wheel gear.From above-mentioned it is thus clear that, the golf car drives the species of machine zero partses and components that the bridge design involves extremely extensive, also almost want to involve all modern machine manufacturings a craft to these zero partses, components and the manufacturing always becoming.This text according to the design method that the tradition drives bridged to carry on the design that the golf car drives bridge.This text makes sure the structure pattern and main design parameter of main parts first;Then make reference to similar drive the structure of bridge, make sure a total design of of project;Finally to 12 class lords, from move cylinder wheel gear, half stalk the wheel gear and the whole float type half stalk strength carry on pit in the school and accept bearings to carry on pit in the life span school towards paying.
This design contains following two greatest hard nut to crackses, one is twist motor exportation the Ju pass ten thousand to spread to move stalk to deliver the motive to behind wheel up, attain better car wheel to lead dint with change direction effective exertion of dint, thus exaltation carry heavy car of drive ability.Two is bad soon while machine is delivering motive toward the both sides half stalk, allow both sides half stalk with dissimilarity of turn to soon revolve, satisfy both sides car wheel possibly with purely roll over of the form make not etc. be apart from to drive, reduce the friction of tire and ground.
This design has a following advantage:Because of is adopt a second class cylinder wheel gear lord to decelerate a machine and make whole after the structure of the bridge simple, manufacturing the craft is simple and thus and consumedly lowered a manufacturing cost.And, raised to spread dynamic credibility.
The biggest characteristics of this design is:The lord deceleration machine adopts traditional cylinder wheel gear to decelerate a machine and have to work compared with other wheel gears steady, noise and vibrate a small advantage, and economy good.
Key word:Golf car;Empress bridge;The second class lord decelerates a machine;Cylinder wheel gear
