摘 要
汽車舉升機在汽車維修行業(yè)是最重要，最基本的工具之一，是將汽車從一個高度提升至另一高度進行維修的設(shè)備，具有至關(guān)重要和不可替代的作用。它能否正常運轉(zhuǎn)會直接影響到維修車輛、維修人員的安全，甚至?xí)苯佑绊懙狡嚲S修業(yè)務(wù)的興衰。
液壓舉升機具有承載力高、適應(yīng)性強、維護及安裝方便等優(yōu)點。它可以適應(yīng)不同類型的車輛維修。隨著汽車工業(yè)的不斷發(fā)展，汽車維修設(shè)備也發(fā)展到一個更高的階段。因而，對液壓雙柱式舉升機的系統(tǒng)運動學(xué)、動力學(xué)的研究很有必要。為以后的研發(fā)、改進提供必要的幫助。
本文針對液壓舉升機的特點和發(fā)展趨勢，以現(xiàn)有的液壓舉升設(shè)備為基礎(chǔ)，改進液壓舉升設(shè)備的液壓系統(tǒng)，本設(shè)計主要進行了液壓系統(tǒng)設(shè)計，確定了液壓系統(tǒng)回路，選擇了控制方式，進行了壓力、流量的計算。對液壓缸、液壓泵、系統(tǒng)中所有的閥進行分析，分析了它們之間所受的壓力、流量等主要參數(shù)之間的關(guān)系。分析了上升、下降過程中，提出了解決方法。采用柱塞式液壓缸和其他方法，解決了雙缸同步問題。

ABSTRACT
The car lifter in the automotive repair industry is the most important and one of the most basic tool is to enhance the car from a height to another height for maintenance of equipment, with vital and irreplaceable role. It can directly affect the normal operation of maintenance vehicles, maintenance personnel, or even directly affect the rise and fall of car repair business.
Hydraulic lift with high capacity, adaptability, and easy maintenance and installation. It can be adapted to different types of vehicle maintenance. With the continuous development of automobile industry, automotive maintenance equipment are also developed to a higher stage. Thus, Hydraulic Auto Lift on the system kinematics, kinetics is necessary. For future research and development, improving the provision of necessary assistance.
In this paper, the characteristics of hydraulic lift and trends, to present the basis of hydraulic lifting equipment, hydraulic lifting equipment to improve the hydraulic system, this design mainly To hydraulic system design, to determine the hydraulic system circuit, select the control means, pressure, flow rate calculations.The hydraulic cylinder, hydraulic pump, the system analyzes all the valves to analyze the pressure between them, traffic, etc. The relationship between the main parameters.Analysis of the rise and fall during the proposed solution.Hydraulic cylinder with piston, and other methods to solve the synchronization problem cylinder.
Keywords: Vehicle lifter; Hydraulic lifter; Hydraulic system; Hydraulic cylinder; Circuit
