Integrated tension device and crawler-type walking machine with same

Abstract

The invention discloses an integrated tension mechanism. The integrated tension mechanism comprises a rear guide base, a front guide base, a shaft, a pull rod and a spring. The rear guide base is provided with a column body and a protruding ring which is integrally formed at the rear end of the column body, and an axial through hole is formed in the rear guide base. The front guide base comprises a barrel body and an outer edge which is integrally formed at the front end of the barrel body, wherein an opening is formed in the front end of the barrel body. A guide wheel support is arranged at the front end of the shaft, and the rear end of the shaft is inserted into an inner cavity in the front guide base in a matched mode and is in sliding seal with the inner cavity. The front end of the pull rod is connected with the front guide base, the rear end of the pull rod penetrates through the axial through hole in the rear guide base, and a limiting mechanism is arranged at the tail end of the pull rod. The column body and the barrel body are sleeved with the two ends of the spring respectively, and the spring is clamped and positioned between the rear guide base and the front guide base. According to the integrated tension mechanism, the inner cavity of the front guide base is directly used as the cylinder body of an oil cylinder, the tail end of the shaft has the piston function in an integrated mode, and the guide bases and the oil cylinder are of an integrated structure, so that an oil cylinder structure of a traditional tension device is simplified, and the assembly difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an integrated tensioning device and a crawler-type traveling machine with the device. Background technique [0002] Crawler-type walking machinery, such as bulldozers, has the advantages of large traction, low grounding ratio, strong climbing ability and small turning radius, so it is widely used in engineering construction. The walking device of crawler-type walking machinery is used to support the body and transmit the engine The torque and rotational motion to the drive wheels are converted into the driving force to push the bulldozer to work and travel. As the core component of the crawler chassis system, the track tensioning device, on the one hand, ensures the proper tension of the track and the driving efficiency of the track system, and on the other hand, absorbs and absorbs the obstacles encountered by the guide wheels and the track during walking. , improve the life ...
