越野车用绞盘液压控制系统设计+CAD图纸
在对野外车辆工作环境和故障的研究后，我们清楚的了解绞盘机在汽车自动救援领域的重要意义。绞盘的使用非常广泛，现在随处可见的建筑工地上，每天上下班经常乘坐的电梯，起重机，码头用来拖拽船只用的绞盘机等等都涉及绞盘原理，自从绞盘机在码头被用来拖拽船只后，喜欢搞设计发明的人们就把它带到了各个领域，随着绞盘的越来越大众化，绞盘的发展变得尤为迅速，从刚开始的单一的电动绞盘，到现在的液压绞盘，PTO绞盘，轮毂绞盘等等，绞盘朝着多向化发展，并且绞盘技术已经变得相当成熟。虽然现在安装绞盘的车辆还占不到一半，但绞盘是所有的车辆都可以安装并能用来野外自救的装置。尤其是在世界上工作环境最差的领域内工作的各型越
野车，几乎都装有电动绞盘机。在世界级的关于越野的大赛更是名门规定所有参赛车辆必须配备车用绞盘。可见，绞盘机对越野车的重要性。考虑到中国庞大的、复杂的地质地貌，山脉丘陵，沼泽，沙漠占了几乎一半的土地面积，在生活生产领域内，车辆往往会陷入一个困境，这时拥有绞车显得特别重要地。

Automotive self-help device
Abstract:Automotive self-help device just as its name implies is to his complete self-help device, self-help device is the most commonly used cars now the winch. With the design of the hydraulic winch below as an example to introduce the winch, hydraulic winch is mainly hydraulic system, braking system, reducer, drum, steel rope. By hydraulic pump hydraulic system is the source of power, among them to extract oil from the hydraulic cylinder through a one-way valve (check valve in this role is to provide inpidual hydraulic oil), and then through the electromagnetic directional valve (feed) when electromagnetic directional valve to play on the left to the next check valve to drive the motor rotation, set up at the second check valve pressure relief valve, when pressure exceeds a certain pressure relief through the overflow valve, oil return process, a filter is used to ensure that the quality of the oil in tank. As car free space is limited so can't choose the hydraulic motor is too big, so to adjust the speed reducer is required to achieve the available drag force, this design USES the secondary planet gear reducer, gear reducer is a total of six gear transmission ratio is 6.26 (the first level, second level distribution ratio is 5, in the first level of transmission planetary wheel as the sun in the second round so as to realize the overall transmission of drive ratio of 31.3, through the role of the after reduction gear reducer on the drum, drum is closed by winding steel cable) is put through the winding drum drive the steel rope direct effects on the car to do drag and drop, the diameter and length of steel rope was selected according to the bearing capacity of the original, the steel cable is wound on the reel, the knot in the work of the steel cable show cricoid and connected to the anchor, the winch design not only adopted a system of hydraulic lock, also plus the mechanical lock brakes, brake system is through the hydraulic oil, turn the brake pads, brake pads, butterfly spring to complete, when the winch hydraulic oil through tubing into the cavity while working to promote fixed mobile pads which promote the movement of the baffle pressure butterfly spring to rotate the fixed brake pads and brake pads separation so that the rotation of the winch can, when need to brake, oil supply is not as long as stopped to brake chamber of the hydraulic oil giant thrust to balance the stretch of butterfly spring, butterfly spring will surely promote the baffles are moving forward, to provide baffle fixed pads combined with
