Novel gearbox technology

Abstract

The invention discloses a novel gearbox technology. A magnetic coupler capable of transferring a torque in a semi-clutch state is used by a gearbox, magnetic couplers capable of transferring torques in a semi-clutch state are mounted at the input or output ends of gear sets with various speed ratios, meanwhile, the gear sets with various speed ratios are made to be simultaneously in the semi-clutch state, and the semi-clutch gear sets are in mutual cooperative operation, as a result, the automatic speed change of the gearbox within a certain speed ratio range is realized. Meanwhile, the gearbox can automatically regulate the self speed ratio according to the input and output states, so that the input and output are simultaneously in the optimal matching state, and the intelligent automatic speed regulating effect is achieved. The gearboxes are connected in series, so that the high speed ratio and multiple speed ratios of a fully-automatic gearbox can be realized. The gearbox is simple and reliable in structure and low in cost and provides a novel platform and design thought for the design and development of the gearbox in future.

Description

technical field [0001] The invention belongs to the mechanical field and relates to the design, production and application of a novel gearbox. Background technique [0002] At present, cars have become the most widely used means of transportation. In addition to the engine, each car is also equipped with a gearbox. Complex usage requirements such as low speed, light load, and heavy load. [0003] However, existing gearboxes, such as MT manual gearboxes, are simple in structure and low in cost, but they are cumbersome to operate, and there is a sudden change in speed ratio during the shifting process, causing mechanical shock, and it is impossible to ensure the optimal match between the engine and the wheels at any time in real time. The AMT gearbox only transfers the shifting process from the human to the machine to realize automation, but its inherent transmission characteristics are the same as those of the MT gearbox. The automation also greatly increases the complexity ...

Problems solved by technology

[0003] However, existing gearboxes, such as MT manual gearboxes, are simple in structure and low in cost, but they are cumbersome to operate, and there is a sudden change in speed ratio during the shifting process, causing mechanical shock, and it is impossible to ensure that the engine and wheels are optimally matched at any time.

The AMT gearbox only transfers the shifting process from the human to the machine to realize automation, but its inherent transmission characteristics are the same as those of the MT gearbox. The automation also greatly increases the complexity of the equipment, and the cost and maintainability are also greatly reduced.

The hydraulic torque converter has better transmission characteristics, but its structure is complicated, the cost is high, and the transmission efficiency is low, so it is not widely used

CVT gearbox has a simple structure and good transmission characteristics, but its load capacity is weak, and the speed adjustment process needs to be automatically adjusted, so its use has great limitations
