Problems solved by technology

Without exception, the above layout schemes and comprehensive methods use multiple planetary rows in series in order to obtain more than 2 speed ratios. Another problem brought about by the series connection of multiple planetary rows is that the transmission efficiency is greatly reduced.

Embodiment Construction

[0044] In order to make the purpose, features and advantages of the present invention more comprehensible, the following is a detailed description of preferred implementation examples in conjunction with the accompanying drawings.

[0045] The present invention is further illustrated by the following examples, but not limited to the following examples.

[0046] The 2n+2 speed changer of the present invention needs to apply angle transmission, and for clearly expressing, the example of angle transmission is as Figure 9 , 10 as shown, Figure 9 Shown is a herringbone tooth surface gear transmission, in which the angle between the axis of the cylindrical gear and the face gear can range from 0° to 180°, but the best angle is 90°. Figure 10 Shown is a straight bevel gear drive. Cylindrical gears, face gears, and bevel gears are the basic elements that constitute the angular planetary row in the present invention. Their gear teeth can be in the form of straight teeth, arc teet...

Abstract

The invention discloses a 2n+2 gear transmission based on an angle gear transmission mechanism (face gear or taper gear transmission mechanism). The 2n+2 gear transmission mainly comprises a box, an input and output shaft, a supporting system, a parallel multi-planet row speed control system based on the angle gear transmission mechanism, a clutch used for controlling gear switching and a brake. Different from a traditional planet transmission, a transmission multi-planet row wheel train can share a planet wheel, a planet carrier and a sun gear, two speed ratios can be increased when one gearelement capable of being switched between the fixed state and the idle state is introduced each time, when the number of the gear elements is n (n is larger than or equal to 1), 2n speed ratios can beobtained, one direct transmission speed ratio and one negative transmission speed ratio can be included, and 2n+2 gears can be obtained. Due to public design of main transmission components such as the sun gear, the planet wheel and the planet carrier, under the condition that the numbers of the gears are the same, the number of the utilized gears is smallest, and the beneficial effects of beingsimple in structure, reliable in operation, high in transmission efficiency and the like are achieved.

Description

Technical field: [0001] The present invention relates to the field of transmissions used in motor vehicles and industrial transmissions, more specifically, the present invention relates to gear transmissions, clutches, brakes, boxes and other components in the power transmission system and their mutual variable dynamic connections The transmission device of the invention specifically relates to a 2n+2 speed transmission based on an angle gear transmission mechanism. Background technique: [0002] The transmission system is located between the prime mover and the working machine. The transmission system can make the output power characteristics of the prime mover (especially the internal combustion engine) suitable for the working needs of the working machine under various working conditions, so that the working machine can work normally or with optimal performance. Generally, the optimal operating speed and torque range of the prime mover is very small, but the speed require...
