HKD1030柴油动力货车设计（总体、车架、制动系设计） 摘 要 在本设计中，外型设计上主要参考了庆铃和其他相关车型。同时做了些改动。在底盘布置和整车布置中，根据人机工程学原理，合理布局人体姿势和座位安排，使驾驶员和乘客坐姿舒适，不易产生人疲劳。现时根据驾驶员和乘客的视野，完成风窗和后视镜和设计，保证驾驶员有良好的视野性。本设计采用以人为本，用途多样，经济实用的原则，进行了合理的布局。 制动系至少有两套制动装置即行车制动装置和驻车制动装置。行车制动装置是用作强制行驶中的汽车减速或停车，并使汽车在下坡时保持适当的稳定车速。驻车制动装置是用作是汽车停在原地或坡道上。　　　　 本设计对鼓式制动器的结构形式进行综合的分析，对六种形式的优缺点作了比较，根据对各种制动器方案对比分析，本设计采用了领从蹄式制动器。其主要优点是：制动器的效能及稳定性均处于中等水平，但由于其在汽车前进与倒退时的制动性能不变，且结构简单，造价较低，也便于附装驻车驱动机构；易于调整蹄片与制动鼓之间的间隙。本次设计中，行车制动系采用人力液压式制动；驻车制动的驱动机构为手动驻车；串联双腔制动主缸，双回路结构。前后制动器都采用领从蹄式鼓式制动器。设计中根据总体参数和制动器的结构与参数，通过理论推导和计算，对该车制动时的制动力和制动力矩等做了细致的分析。 关键词：底盘，外形，制动系统，制动器，行车制动系，应急制动 HKD1030 diesel-powered truck design (overall, frame, brake system design) ABSTRACT In this design, in the outlook design has mainly referred to QingLing and other related vehicle types.　Simultaneously has made a modification. In the chassis arrangement and entire vehicle arrangement , according to the man-machine engineering principle, the reasonable layout human body posture and the seat arrangement, causes the pilot and the　passenger sitting posture is comfortable, Not easy to produce wearily. Simultaneously acts according to the pilot and passenger’s field of vision, Becomes common practice the window and the rear view mirror design, Guaranteed the pilot has the good field of vision . This design uses humanist, the use is diverse, Economical practical principle, Has carried on the reasonable layout. Break system consists of service break arrangement and parking break arrangement. Service break system used to force the vehicle to show down and keep a steady speed when down grading. The parking break system intended to hold the vehicle immovable when parked on an incline. This design carries on the synthesis analysis to the drum type of the brake structural style. It compares the advantages and disadvantages of six kinds of forms, and according to this contrast analysis of the kinds of the brake plan, the horseshoe type’s brake is adopted. Its main merits are that although the bra
