黑龙江工程学院本科生毕业设计附录B Hydraulic System Design In recent years, Chinas booming auto industry, especially the car trip Industry. For many years into the average family car has become a dream now Real. Vehicle maintenance industry also received a strong development of the various repair The rapid expansion of demand for equipment. Vehicle repair workshop is required lift The most important maintenance machinery. Car lift would be required of the role i s the level of maintenance of vehicles To a suitable height, so that the maintenance workers in the automotive chassis Carry out maintenance on the car below. Car lift columnwillgenerally be divided into And two kinds of shear-type 1. No matter what kind of demand from its two Side of the vehicle lifting the level of synchronization can not occur cornering. And the car at the end of Bottom plate must be empty, so as to facilitatemaintenance operations workers. This Car lift required on both sides of the lifting device must be isolated , And that increase or decrease on both sides and must be fully synchronized. By The weight of the vehicle are generally larger, together with its own lifting device Weight lifting force larger demands and requirements of the landing and taking off a very flat Stability, it is generally used auto lift hydraulic drive system Action.Is on the authors developed a hydraulic system into the car lift Line introduced. auto lift hydraulic system design requirements Automotive lift hydraulic system, in addition to the requirements in certain areas Insiders on both sides of the vehicle from the car lift and llsimultaneously, but also For their car can stop at any height and to maintain the fixed faTo Workers have different height, different locations in the maintenance can be arbitrary Adjust the height, the most convenient way to carry out repairs. Therefore, the hydraulic system will Required to maintain the functional position. In addition, due to the weight of larger vehicles, Once the hydraulic system fails, gravity lift in the car The role will rapidly decline, may be the next car maintenance workers Pose a threat to safety of life, lift the car above have been The risk of break. Therefore, in order to prevent this from happening, give Or machine must have a mechanical locking device. Mechanical locks were installed by .In lifting the fuel tank and the piston rod at the top of the lateral arm associated with the lifting of sales Axis composed of two serrated rack. Installed outside the fuel tank Fixed rack, and installed in the pin on the rack with the Pistons Poles moved around the pin and to a certain point of the swing to do in order to To achieve separation and the two mesh rack. When the lifting arm at a location Status or failure of the hydraulic system, oil pressure falls below a certain value, the Rack will move in its own gravity and the role of the spring force with static gear Article mating, mechanical lock locked, so that lift arm will not drop, so that To ensure that the repair works and the car will not be dangerous.附录D 汽车举升机液压系统设计近年来，我国汽车业蓬勃发展,尤其是轿车行业。多年来轿车进入普通家庭的梦想已经成为现实。汽车维修行业也随之得到大力发展,各种维设备的需求迅速扩大. 汽车举升机是维修厂必备的,也是最重要的维修机械.汽车举升机的作用是将需要维修的汽车水平提升到合适的高度,以便于维修工人在汽车底盘方对汽车进行维修. 汽车举升机一般分为立柱式和剪式2种。盘下方必须为空的,以方便工人进行维修作业. 这就要求汽车举升机两侧的举升装置必须是分离的,且两侧的上升或下降又必须是完全同步的. 由于汽车的重量一般都较大,再加上举升装置自身的重量,要求举升力较大,而且升降时要求非常平稳,所以汽车举升机一般都采用液压系统进行驱动. 现就作者开发的一种汽车举升机液压系统进行介绍.汽车举升机液压系统,除要求能在一定的范围内从汽车两侧将汽车同步举升和下降外，还要求其能使汽车在任意高度停止并保持不动。 以便不同身高的工人，在维修不同置时可以任意调整高度,最方便地进行维修。因此,液压系统必须具有定位保持功能。另外，因汽车的重量较大，一旦液压系统出现故障，举升机举臂在汽车重力的作用下会迅速下滑，可能会对车下维修工人的生命安全造成威胁，举升机上面的汽车也有被摔坏的危险。所以,为了防止这样的情况发生,举升机必须具有机械锁定装置。机械锁由分别安装在举
