Description

一种可封装的台车架承重轮缓冲装置A kind of load-bearing wheel cushioning device of the trolley frame that can be packaged

技术领域 technical field

本发明涉及一种缓冲装置,尤其是涉及一种可封装的台车架承重轮缓冲装置。 The invention relates to a buffer device, in particular to a packable load-bearing wheel buffer device for a trolley frame.

背景技术 Background technique

履带式车辆在各种运输领域都比较广泛地被应用,有履带式拖拉机,履带式装甲车,坦克,包括现在农用小型的联合收割机,微耕机。在履带式车辆中,承重轮的作用是非常重要的,几乎承担了车辆上的所有载重量,对于履带式的车辆,其越障能力也有要求,保证车辆在行驶的过程中,能够平稳顺利地通过障碍物。 Tracked vehicles are widely used in various transportation fields, including tracked tractors, tracked armored vehicles, tanks, including small agricultural combine harvesters and tillers. In tracked vehicles, the role of the load-bearing wheels is very important, almost bearing all the load on the vehicle. For tracked vehicles, its obstacle-surmounting ability is also required to ensure that the vehicle can run smoothly during the driving process. through obstacles.

传统的台车架承重轮缓冲装置是简单的连杆和弹簧组成的,这种装置的优点是简单,容易制造,但是缺点是这种装置不能进行封装,即这种装置的关键零部件,如不能对弹簧进行保护,在行驶的过程中,弹簧容易碰到其它硬质的东西时容易受损,影响其缓冲能力,由于长期裸露在外部,并且一般的履带车行驶的路况条件比较恶劣,接触到的其它物质也比较多,这些物质容易造成弹簧的腐蚀,影响其性能,进而影响车辆的行驶性能。车辆在行驶的过程中,对于缓冲装置,弹簧的形变量越大,越过障碍物时,对剧烈震动的吸收效果就越好。 The traditional trolley frame load-bearing wheel buffer device is composed of simple connecting rods and springs. The advantage of this device is that it is simple and easy to manufacture, but the disadvantage is that this device cannot be packaged, that is, the key components of this device, such as The spring cannot be protected. In the process of driving, the spring is easy to be damaged when it touches other hard things, which affects its cushioning ability. There are also many other substances, which are easy to cause corrosion of the spring, affect its performance, and then affect the driving performance of the vehicle. When the vehicle is running, for the buffer device, the greater the deformation of the spring, the better the effect of absorbing severe shocks when passing over obstacles.

针对以上问题,笔者提出一种可进行封装的台车架承重轮缓冲装置,该装置可以对弹簧进行封装,保证弹簧不与外界进行接触,从而可以避免氧化和损伤。该装置利用两个传动比比较大的齿轮可以辅助增大弹簧的形变量。 In view of the above problems, the author proposes a load-carrying wheel buffer device that can be encapsulated. This device can encapsulate the spring to ensure that the spring does not come into contact with the outside world, thereby avoiding oxidation and damage. The device utilizes two gears with relatively large transmission ratios to assist in increasing the deformation of the spring.

工作原理为,车辆咋行驶的过程中,在平坦路面上行驶时,两承重轮在高刚度弹簧的拉力作用下,保持两轮的高度和距离相同,车辆平稳行驶;当遇到障碍物时,由于承重轮回受到障碍物的阻碍作用,承重轮臂会摆动,摆动的承重轮臂会带动齿轮转动,两个齿轮中的任何一个转动都会带动另一个齿轮的转动,由于两者之间的传动比较大,任何一个齿轮的轻微的转动都会引起两者之前的相对转动角度增大,从而带动两摆臂的相对转动量增大,进而带动弹簧发发生形变,发生变形的弹簧会产生弹性力,弹性力反作用在摆臂上,使弹簧趋于原位。弹簧在发生形变的过程中会对车辆在越障的过程中产生的震动进行吸收,保证车辆的稳定性。 The working principle is that when the vehicle is running on a flat road, the height and distance of the two load-bearing wheels are kept the same under the tension of the high-stiffness spring, and the vehicle runs smoothly; when encountering an obstacle, Because the load-bearing cycle is hindered by obstacles, the load-bearing wheel arm will swing, and the swinging load-bearing wheel arm will drive the gear to rotate, and the rotation of any one of the two gears will drive the rotation of the other gear. Large, a slight rotation of any gear will cause the relative rotation angle of the two to increase, thereby driving the relative rotation of the two swing arms to increase, which in turn drives the spring to deform, and the deformed spring will generate elastic force. The force reacts against the swing arm, tending the spring toward its original position. In the process of deformation, the spring will absorb the vibration generated by the vehicle when it is overcoming obstacles, so as to ensure the stability of the vehicle.

The device is a closed device, which can protect the spring. The device uses two gears with a large radius difference to increase the transmission ratio and assist in increasing the deformation of the spring, which can absorb severe vibrations.
