Description

A kind of load-bearing wheel cushioning device of the trolley frame that can be packaged

technical field

The invention relates to a buffer device, in particular to a packable load-bearing wheel buffer device for a trolley frame.

Background technique

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.

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.

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.

Contents of the invention

The purpose of the present invention is to solve the problem that the spring of the existing buffer device is easily damaged, and to provide a load-carrying wheel buffer device that can be packaged.

The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is:

A load-carrying wheel buffer device that can be packaged includes load-bearing wheel I, load-bearing wheel II, load-bearing wheel arm I, load-bearing wheel arm II, an upper shell, a lower shell, a pinion gear and a large gear, the upper shell and The lower shell fits together to form a sealed shell and is installed on the vehicle frame. One end of the load-bearing wheel arm I is hinged to the load-bearing wheel I, and the other end is fixed with a connecting shaft I. The end of the connecting shaft I away from the load-bearing wheel arm I passes through The casing extends into the casing, the pinion is set in the casing and fixed on the connecting shaft I, the pinion is also fixedly connected with the swing arm I, one end of the load-bearing wheel arm II is hinged with the load-bearing wheel II, and the other end is fixed with a The connecting shaft II, the end of the connecting shaft II away from the load-bearing wheel arm II passes through the casing and extends into the casing, the large gear is arranged in the casing and fixed on the connecting shaft II, and the large gear is also fixedly connected with the swing arm II, the large gear It is arranged in mesh with the pinion, and the ends of the swing arm I and the swing arm II away from the gears are provided with protrusions, and a spring is sleeved between the protrusions of the swing arm I and the swing arm II.

Described swing arm I is perpendicular to the straight line where the center of load-bearing wheel I and load-bearing wheel II is.

The swing arm II is perpendicular to the straight line where the centers of the load-bearing wheel I and the load-bearing wheel II are located.

The swing arm I and the swing arm II are arranged parallel to each other.

The upper shell and the lower shell are fixed through bolt connection.

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 beneficial effects of the present invention are: the present invention is more practical for general crawler wheel vehicles and has strong versatility. 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.

Detailed ways

Shown in Fig. 1, Fig. 2 and Fig. 3, the specific implementation method is as follows:

A load-carrying wheel buffer device that can be packaged, comprising load-bearing wheel I1, load-bearing wheel II8, load-bearing wheel arm I2, load-bearing wheel arm II, upper shell 9, lower shell 10, pinion 3 and bull gear 7, The upper shell 9 and the lower shell 10 fit together to form a sealed shell and are installed on the vehicle frame. One end of the load-bearing wheel arm I2 is hinged to the load-bearing wheel I1, and the other end is fixed with a connecting shaft I11, which is far away from the load-bearing One end of the wheel arm I2 passes through the housing and extends into the housing. The pinion 3 is arranged in the housing and fixed on the connecting shaft I11. The pinion 3 is also fixedly connected with the swing arm I4. One end of the load-bearing wheel arm II is connected to the load-bearing wheel. II8 is hinged, the other end of which is fixed with the connecting shaft II, and the end of the connecting shaft II away from the load-bearing wheel arm II passes through the housing and extends into the housing.

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 weighing cycle is hindered by obstacles, the weighing wheel arm will swing, and the swinging weighing 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. The transmission is relatively large, and 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 produce elasticity. Force, the elastic force reacts on the swing arm, making the spring tend to the 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.
