continuous shift transmission

Abstract

The invention provides a continuous gear shifting speed changer which can simultaneously carry out three actions of a gear-exchange combined clutch of a cut-off clutch of a traditional speed changer. A speed change basic unit is a shifting-fork straightly-sliding multi-gear exchange gear set. A group of shifting forks can slide in a straight line to exchange multiple gears. Power input is distributed into three clutches through gears (picture 7), the three clutches (1, 3 and 5) are controlled by a gear shifting wheel (17), three gear sets are simultaneously controlled by the gear shifting wheel, two standby clutches are both in a separation state, and the gear shifting wheel can rotate at 120 degrees to carry out separation and reunion action on the two clutches in the three clutches. Meanwhile, gear position change action can be carried out by the gear set under another separation clutch. The three gear sets share an output shaft gear set (11) to finish torque output. The gear shifting wheel can rotate forwards and reversely to shift up and shift down, so that the purpose of shifting up and shifting down continuously and quickly is achieved. A gear-shifting stepping motor (20) is accurate to control and can enable output rotation speed to improve stably and reduce stably.

Description

Technical field [0001] The present invention relates to the automotive industry. It can realize speed change without power adjustment and uninterrupted power output during speed change. It is a transmission with extremely fast shifting speed, stable continuous shifting action and minimal pure mechanical loss. It can be applied to the uninterrupted power transmission of automobiles, cranes, and precision machine tools, and can also be used for the starting acceleration of gliding aircraft. Background technique [0002] At present, most of the shifting gears of automobiles (including heavy-duty vehicles) adopt manual shifting, and some of the current automatic transmissions use hydraulic torque converters, which cause great power loss. Although new automatic transmissions have been improved in recent years, they are still in When changing gears frequently at low speeds, the clutch loss is extremely high, and the gearbox protection device has to reset the gear to zero, and the...

Problems solved by technology

[0003] In order to overcome the many shifting actions of the existing manual transmission, the power loss of the current automatic transmission, and the problems caused by frequent shifting, the present invention provides an automatic transmission capable of continuous shifting, which can separate the clutch gear from the traditional transmission. The three actions of the bit exchange combined with the clutch are executed at the same time, realizing continuous automatic shifting, and the output speed of the transmission is steadily increased and decreased
