Description

technical field [0001] The invention relates to the technical field of tracked vehicles. Background technique [0002] With the maturity of rubber track technology, rubber track running devices have been widely promoted and applied on many vehicles. Due to the continuous interaction between the rubber track and the ground during travel, high requirements are placed on its performance; the correct design of the driving angle of the rubber track determines whether it can be stably meshed with the track drive wheel, and whether the track drive wheel can be reliably The transmission of sufficient driving torque directly affects the performance and service life of the rubber crawler traveling device, and then affects the construction quality and construction period. Therefore, more and more attention is paid to the test of the driving performance of the rubber crawler. [0003] At present, the design of the driving angle and the driving wheel of the rubber track, especially the ...

Problems solved by technology

[0003] At present, the design of the driving angle and the driving wheel of the rubber track, especially the coreless gold rubber track, mainly depends on experience and lacks reliable test data as a basis. The wrap angle of the drive wheel is different, the drive wheel is different, the traction force that can be provided is different, and the shape and material of the track drive angle are also different. Therefore, there is an urgent need for a general test device to determine the driving torque that the drive angle can withstand. Predict the life of the rubber track driving angle, verify the stability of the rubber track driving angle and the meshing of the driving wheel, so as to provide a basis for the design of the rubber track running device, analyze and predict the working characteristics of the rubber track vehicle, and improve the working performance of the rubber track running device
