Problems solved by technology

However, the power coupling mechanism is complex, requiring 3 to 4 planetary rows to be connected with each other to form a two-degree-of-freedom planetary mechanism, and its internal components are likely to generate cyclic power during the steering process of the tracked vehicle, which affects the improvement of transmission efficiency

Abstract

The invention belongs to the technical field of caterpillars and particularly relates to hybrid power transmission. A series-parallel connection hybrid power transmission device of a caterpillar comprises a front transmission part, a left side driving part, a left side output speed changing mechanism, a right side driving part, a right side output speed changing mechanism, a middle power coupling mechanism and a sell. According to the series-parallel connection hybrid power transmission device of the caterpillar, in view of motor power using, a straight-driving and steering power coupled double-motor-driving series hybrid power mode has the advantages that the structure is simple, double-current zero-differential-type steering motors and steering zero shafts can be omitted, and reducing of the longitudinal space of the transmission device is facilitated; through the middle power coupling mechanism, efficient transmission of steering reflux power can be achieved, and the technical requirements of the motors are effectively lowered; and through the middle power coupling mechanism, a path of engine power is introduced, during high speed or a stable driving working condition, a parallel connection hybrid power working condition is achieved, the two driving motors can still be used as steering motors to be responsible for steering of the caterpillar.

Description

technical field [0001] The invention belongs to the technical field of tracked vehicles, and in particular relates to a hybrid power transmission. Background technique [0002] The research on the hybrid power transmission of tracked vehicles at home and abroad mainly focuses on the double-side motor independent drive type and the double-flow zero-differential speed type. [0003] The structure of the double-side motor independent drive type is simple, and the two drive motors drive the crawlers on both sides respectively. The speed of the motors on both sides is controlled to be consistent in the straight driving condition; when turning, it is realized by controlling the speed difference of the motors on both sides. When the tracked vehicle turns with a small radius, the inner track will generate steering return power. In order to make full use of this part of power, the inner and outer drive motors must have a large power capacity, so that the steering return power is gene...
