摘要

随着生活水平的提高，人们对汽车提出越来越高的要求，包括研制节油汽车和开发应用新能源，有关法规对汽车的排放和噪声提出了更严格的要求；对汽车安全性提出了更高的要求，达到乘用汽车有安全感、愉快感，汽车发生碰撞事故时能妥善地保护乘员；对汽车提出舒适性的要求，不仅坐在汽车里舒服，而且能与外界进行信息交流。当然，负荷车也属于车辆的一种，因此它也应具备一般车辆所需的美观、舒适、安全等。

负荷车是给被测拖拉机施加牵引负荷的车辆，模拟拖拉机牵引作业工况进行检测，用来评价拖拉机牵引性能和质量状况，是拖拉机生产企业和科研单位研发拖拉机必不可少的设备。我国的负荷车状况有自行研制，也有从国外引进，已经经历了将近25年的发展。

负荷车是拖拉机牵引性能试验必不可少的重要设备之一，包括车体、数据采集器、电荷放大器、计算机数据采集系统和供给电源五大部分。

本设计的负荷车轴数为单轴，最小转弯半径为4m，悬架采用钢板弹簧悬架，采用周边式车架，底盘稳固可靠，汽车外形在充分考虑布置的前提下，尽可能的采用流线型设计，不仅降低了风阻，而且外形美观大方，动感十足。

THE DESIGN OF TRACTION MODIFIED LOAD TRUCKS

ABSTRACT

With the improvement of living standards, people in the car ever-increasing demand, including the development of fuel-efficient vehicles and the development and application of new energy, and the relevant regulations on vehicle emissions and noise of the more stringent requirements; Automobile safety of a higher demand by the use of motor vehicles to achieve a sense of security, happiness flu, Vehicle collision accidents will be able to properly protect the crew; comfortable in the car made the request, sitting in vehicles not only uncomfortable, but also with the outside world for the exchange of information. Of course, the car belonging to load a vehicle, so it should have a general appearance of the vehicles, comfort, safety and so on.

Load car is measured to exert traction tractor load of vehicles, tractor-drawn simulated operating conditions detection, Tractor traction used to evaluate performance and quality, Tractor production of enterprises and scientific research units essential to the development of tractor equipment. China's car load situation developed, but also introduced from abroad, has experienced nearly 25 years of development.

Load tractor-drawn vehicles is essential to the performance test one of the important equipment, including body, data acquisition devices, charge amplifier, computer data acquisition system and the five most power supply.

The design of the axle load at uniaxial, the minimum turning radius of 4 m, using leaf spring suspension suspension, using peripheral-type trailers and chassis solid and reliable vehicle in the shape of the full layout of the premise, The possible use of aerodynamic design, not only reduce the wind, but pleasing in appearance generous, exciting full.

KEY WORD : generally, safe, comfortable, beautiful, exciting
