Embodiment Construction

[0015] refer to figure 1 , image 3 and Figure 4 As shown, a shock-absorbing tensioning device for triangular track wheels consists of two symmetrical "C-shaped" webs 7, a horizontal rib 15, an inner vertical rib 16 and a "Γ"-shaped outer Ribs 18 are welded into mounting brackets, wherein two webs 7 , inner vertical ribs 16 , and outer ribs 18 form a damping chamber 23 , and a shock absorber 20 is arranged in the damping cavity 23 .

[0016] Limiting grooves 21 are arranged below the spoke plates 7 on both sides of the mounting bracket, and the axles of the crawler wheels pass through the limiting grooves 21 and are connected with the shock absorbers 20 in the damping cavity, which can limit the up and down swing range of the axles. A bronze sliding bearing 12 can be further provided on the side to avoid abrasion of the wheel shaft and the spoke plate 7.

[0017] A tensioning device is provided in the middle of the inner vertical rib plate 16 outside the shock absorbing ca...

Abstract

The invention discloses a damping and tensioning device used for a triangle crawler wheel. The damping and tensioning device is characterized by comprising a mounting bracket formed by connecting two symmetrical 'C-shaped' radial plates, one horizontal ribbed plate, one interior vertical ribbed plate and one 'Gamma'-shaped exterior ribbed plate, wherein a damping cavity is formed among the two 'C-shaped' radial plates, the interior vertical ribbed plate and the exterior ribbed plate; and a damping device is arranged in the damping cavity. Limit slots are arranged below the radial plates at the two sides of the mounting bracket, a wheel axle of the crawler wheel penetrates the limit slots to be connected with the damping device in the damping cavity; and the middle part of the interior vertical ribbed plate outside the damping cavity is provided with a tensing device connected with a base frame of the crawler wheel. In the invention, the damping device and the tensioning device are designed into a whole, structure is simple, layout space is saved, adjustable preloading of the damping device and adjustable tensioning of a crawler are realized, and the problems of vibration and deflection of the triangle crawler wheel, especially a heavy vehicle crawler wheel are effectively solved.

Description

technical field [0001] The invention relates to a shock absorbing and tensioning device for track wheels, in particular to a shock absorbing and tensioning device for replaceable triangular track wheels. Background technique [0002] The triangular track wheel is a device that can quickly exchange wheel tracks on wheeled vehicles, so that wheeled vehicles can meet the driving and operating requirements in harsh terrain conditions such as mountains, deserts, swamps, ice and snow. It greatly expands the application range of wheeled vehicles and overcomes the constraints of various unfavorable terrain conditions on mechanical operations. It has been widely used in military vehicles, agricultural operation machinery, lifting and transportation machinery in foreign countries. By improving the structure, adopting new materials and new technologies, the service life is continuously improved, and it is developing in the direction of lightweight, large-scale, high-strength, serializ...
