Driving wheel for tracked vehicle

Abstract

The invention discloses a driving wheel for a tracked vehicle. The driving wheel comprises a driving assembly, a mounting plate, a first reinforcing rib, a second reinforcing rib, a first through hole, a locking head, a second through hole, a first fixing block, a base plate, a groove, a limiting ring, a fixing ring, a locking rod and a spring. Two sides of the first fixing block are fixedly connected with centers of the opposite sides of the mounting plate correspondingly. A fixed arm is arranged on a periphery of a driving gear; the top of the fixed arm is a friction driving surface; therefore, a crawler belt is driven by the driving gear and a friction force; a load of the driving gear is favorably reduced; the service life of a crawler system is prolonged; and through the design of thefirst reinforcing rib and the second reinforcing rib, the structural strength of the driving wheel is enhanced, a situation that the driving wheel is damaged and broken is avoided, the locking rod and the locking head are pushed through the elastic force of the spring, therefore the locking head and the driving shaft are connected in a clamped mode, and installation stability of the driving wheelis facilitated.

Description

technical field [0001] The invention relates to the technical field of drive wheels, in particular to a drive wheel for crawler vehicles. Background technique [0002] The crawler drive wheel is an important part of the crawler chassis. The drive wheel rotates through the rotation of the wheel shaft to drive the crawler meshed with the drive wheel. The crawler has a large contact area with the ground, stable driving, and strong grip, so it is widely used in Agriculture, military and other aspects. [0003] At present, the driving mode of the track mainly relies on the outer ring teeth of the driving wheel to drive the iron core embedded in the track. This driving mode only relies on the gear teeth to drive, which will cause the wear of the driving wheel and the iron core during use and affect the service life. Seriously even It will cause the iron core to come out, which will cause damage to the track. At the same time, the driving wheel needs to bear a large load when work...

Problems solved by technology

[0003] At present, the driving mode of the track mainly relies on the outer ring teeth of the driving wheel to drive the iron core embedded in the track. This driving mode only relies on the gear teeth to drive, which will cause the wear of the driving wheel and the iron core during use and affect the service life. Seriously even It will cause the iron core to come out, which will cause damage to the track. At the same time, the driving wheel needs to bear a large load when working. On the shaft, long-term work will produce axial shaking, which will cause loose parts and seriously affect the safety of the drive wheel.
