Embodiment Construction

[0016] figure 1 Among them, the gear and rolling cone compound continuously variable transmission is divided into two rows of gear sets, which are the first gear set and the second gear set. The first gear set is responsible for the gear transmission of 2nd, 4th, 6th and 8th gear. Group 2 is responsible for gear transmission of 1st, 3rd, 5th and 7th gears. figure 1 The sleeve in the gear is installed on a freely slidable spline shaft. Under the action of external force, the sleeve is pushed into the corresponding gear by the shift fork, and the two gears are meshed to output power.

[0017] figure 2 It is the top view of the compound continuously variable transmission of gears and rollers. The two rows of speed change gear sets are respectively located on both sides of the rollers. There is a certain pressure between the lower roller cones. When the lower roller cone rotates, it drives the intermediate transmission part and the upper roller cone to rotate together. At the s...

Abstract

The invention relates to a compound infinitely variable transmission integrating gear engagement drive and rolling cone friction drive. Especially, gear synchronization and infinitely variable speed change are achieved by utilizing two rolling cone circumference faces and a friction force of an intermediate drive part, so that seamless butt joint of rotation speed synchronization and infinitely variable speed change is completed in the process of switching a separation state to an engaged state of a gear set. Due to the fact that gear engagement is completed by compounding the conical circumference faces, a spline shaft and a sleeve, a control mechanism for gear shifting is simplified, the transmission ingeniously integrates gear engagement drive and infinitely variable-speed frictional drive of a rolling cone together and has the advantages of smooth CVT drive, oil saving and DCT rapid gear shifting, and the drive efficiency is far higher than a frictionally driven CVT transmission. The gear and rolling cone compounded infinitely variable transmission is used for a speed changing device, the design and manufacturing of the speed changing device can be simplified, the power transmission efficiency and reliability of the transmission are improved, and the purposes of smoothness and oil saving are achieved.

Description

technical field [0001] The present invention relates to a gear and cone compound continuously variable transmission, in particular, it provides a continuously variable transmission which combines gear meshing and rolling cone friction transmission, so that smooth linear seamless gear shifting can be realized during the switching process of each gear set. At the same time, it also has the function of DCT quick shift, which is suitable for use on medium and small vehicles. Background technique [0002] Gear transmission is recognized as a transmission system with high transmission efficiency, small device size and simple structure, but cars with AT and AMT transmissions using gear transmission will have a more obvious "frustration" during the shift process, while DCT transmissions have Small-displacement engines suffer from insufficient torque at low speeds, and complex structures increase the probability of failure. Although CVT transmissions are smooth and fuel-efficient, th...
