Abstract

The invention relates to a crawler-type traveling power transmission, which comprises an engine, a hydraulic torque converter, a hydraulic gearbox and a power-transmission output system, wherein a power output shaft of the engine is connected with an elastic connecting plate of the hydraulic torque converter; the power output shaft of the hydraulic torque converter is connected with an input assembly of the hydraulic gearbox; the output end of the hydraulic gearbox is a gear shaft; the power of the gear shaft is transmitted to a second shaft main gear and a second shaft pinion by a first shaft; a variable speed control device and a steering control device are arranged outside the second shaft main gear and the second shaft pinion; and the output shaft of the steering control device is a final-drive driving shaft. The crawler-type traveling power transmission has the advantages of automatic torque conversion, suitability for operation with large amplitude load change, rational drive structure and high drive efficiency.

Description

technical field [0001] The invention relates to a power transmission mechanism, in particular to a continuously variable speed transmission device for crawler vehicles. Background technique [0002] Generally, both wheeled and tracked tractors in China use mechanical friction clutch transmission. Whether it is a dry or wet clutch, its performance requirements are very high, and it is required to be able to reliably transmit the full torque of the engine without slipping after engagement; the separation must be thorough and rapid; the engagement should be smooth, so as to reduce the impact of the tractor during start-up. load; the moment of inertia of the driven part is small to reduce the impact load when the gearbox is in gear; it has good heat dissipation and is easy to operate. Moreover, the mechanical friction clutch is not suitable for operations with large changes in external load, because when the resistance encountered by the vehicle is getting larger and larger, it...
