Description

Multi-gear overrunning transmission module and application thereof

Technical Field

The invention relates to a multi-gear overrunning transmission module and application thereof, and belongs to the technical field of transmission.

Background

A typical machine generally consists of a prime mover, a working machine, and a transmission. The transmission device is positioned between the prime mover and the working machine and is used for transmitting the power of the prime mover to the working machine after speed change. Because the actual operating condition is more complicated, a plurality of transmissions need to set up a plurality of fender positions to make the prime mover satisfy the needs in all aspects such as dynamic property, economic nature, travelling comfort of work machine. However, in general, a transmission needs to be shifted by means of a complicated electric control system, a hydraulic system and other driving gear shifting devices, so that the control system and the transmission are relatively complex in structure, relatively high in cost and relatively low in reliability. Therefore, it is an urgent need to develop a transmission device that has a simple structure and low cost and can meet various requirements of a prime mover and a working machine.

Compared with the prior art, the multi-gear overrunning transmission module MF has the following advantages:

(1) simple structure, reliability are high: because the multi-gear overrunning transmission module MF adopts at least one overrunning clutch device FC for power switching, the transmission module is simplified on the whole, and the whole structure of the transmission module is relatively simple; in addition, the buffer damping device DP is adopted to filter out excessive impact and load in the gear shifting process and the power transmission process, so that the overall reliability of the transmission module is high; and the transmission module is assisted by the gear shifting device GS for power switching, and the multi-gear overrunning transmission module MF can easily realize various power transmission functions.

(2) The control difficulty is low: for the multi-gear overrunning transmission module MF without the overrunning clutch actuating device AD, the locking and unlocking states of the overrunning clutch device FC are automatically completed by the multi-gear overrunning transmission module MF, the overrunning clutch device FC does not need to be additionally controlled, gear switching of the multi-gear overrunning transmission module MF can be realized by setting the power of a power source and switching the power direction, and the control difficulty is low. For the multi-gear overrunning transmission module MF assisted by the overrunning clutch actuating device AD, the overrunning clutch actuating device AD only controls the one-way clutch function of the overrunning clutch actuating device AD (in many cases, the operation of the overrunning clutch actuating device AD can be manually completed or set manually), and under a certain one-way clutch function condition, the locking and unlocking actions of the overrunning clutch device FC are automatically completed by the overrunning clutch actuating device AD, so that the requirement on the gear shifting control is lower on the whole.

(3) High modularization level, strong expandability and wide application: since the majority of the components of the multi-gear overrunning transmission module MF are standard parts or components, the multi-gear overrunning transmission module MF has a simple structure, which makes it easy to manufacture and assemble into an integrated transmission module. The module is matched with other transmission devices for use, can be applied to a plurality of transmission fields, has wide application, and opens up a brand new view for the structural modification and the new function development of the existing transmission system.

(4) The gear shifting process time is short and the power is not interrupted: because the overrunning clutch device FC is adopted to assist the gear shifting device GS to perform power switching, and the locking and unlocking states of the overrunning clutch device FC are instantly completed according to the relative rotation movement trend of the active part and the passive part of the overrunning clutch device FC (namely the directions of loads or torques respectively applied to the active part and the passive part of the overrunning clutch device FC, namely the acceleration directions), the multi-gear overrunning transmission module MF can sequentially perform switching of a plurality of gears under the condition that power is not interrupted.

(5) The method is suitable for batch production and low in overall manufacturing cost: the components of the multi-gear overrunning transmission module MF are mostly parts or components commonly used in a common transmission device, so that the manufacturing process and the assembly process are simple and easy to realize; in addition, the application prospect is very wide, so that the parts or components of the multi-gear overrunning transmission module MF can be produced in a large scale, and the integral manufacturing cost is comprehensively reduced.

When the second active half-clutch ZF2 has a reverse rotation motion or a reverse rotation motion trend relative to the second passive half-clutch BF2 or the second passive half-clutch BF2 has a forward rotation motion or a forward rotation motion trend relative to the second active half-clutch BF2 as shown in fig. 1, the second overrunning clutch FC2 is in a locked state, and the second active half-clutch ZF2 is relatively fixed in the forward rotation or reverse rotation direction relative to the second passive half-clutch BF 2; when the second active half-clutch ZF2 has a forward rotation motion or a forward rotation motion trend relative to the second passive half-clutch BF2, or the second passive half-clutch BF2 has a reverse rotation motion or a reverse rotation motion trend relative to the second active half-clutch BF2, the second overrunning clutch FC2 is in an unlocked state, and at this time, the second active half-clutch ZF2 is rotatable in a forward direction relative to the second passive half-clutch BF2, or the second passive half-clutch BF2 is rotatable in a reverse direction relative to the second active half-clutch ZF 2.

As shown in fig. 1 and table 1, the multi-gear overdrive module MF can realize at least three forward gears and one reverse gear function. When the first driven gear W1 is engaged with the first output shaft 2 by the first shifting device GS1, the multi-speed overdrive module MF has two forward gears. When the reverse driven gear W9 is engaged with the first output shaft 2 by the first shifting device GS1, the multi-gear overdrive module MF has a forward gear and a reverse gear.

As shown in fig. 1 and table 1, when the first driven gear W1 is engaged with the first output shaft 2 by the first shifting device GS1 and when the first input shaft 1 is positively rotated to input power or has a tendency to move in a positive direction, the multi-speed overdrive module MF is in a first forward speed state. At this time, the first active half-clutch ZF1 has a forward rotation motion or a forward rotation motion trend with respect to the first passive half-clutch BF1, the second active half-clutch ZF2 has a forward rotation motion or a forward rotation motion trend with respect to the second passive half-clutch BF2, the first overrunning clutch FC1 is in a locked state, and the second overrunning clutch FC2 is in an unlocked state.

Namely, when the first input shaft 1 positively rotates to input power, the first output shaft 2 positively rotates to output power.

As shown in fig. 1 and table 1, when the first driven gear W1 is engaged with the first output shaft 2 by the first shifting device GS1, and when the first input shaft 1 is reversely input with power or has a tendency to move reversely, the multi-speed overdrive module MF is in the second forward speed state.

The power of the first input shaft 1 is transmitted to the first output shaft 2 sequentially through the second driving gear P2 and the second driven gear W2, and the speed ratio r1 between the first input shaft 1 and the first output shaft 2 is-Z5/Z2. That is, when the first input shaft 1 reversely rotates to input power, the first output shaft 2 normally rotates to output power.

As shown in fig. 1 and table 1, when the reverse driven gear W9 is engaged with the first output shaft 2 by the first shift device GS1 and when the first input shaft 1 is in the forward rotation to input power, the multi-speed overdrive module MF is in the first reverse state. At this time, the power of the first input shaft 1 is transmitted to the first output shaft 2 sequentially through the reverse drive gear P9, the reverse driven gear W9, and the first shift device GS1, and the speed ratio r1 between the first input shaft 1 and the first output shaft 2 is — Z6/Z3. That is, when the first input shaft 1 is rotated in the forward direction to input power, the first output shaft 2 is rotated in the reverse direction to output power.

As shown in fig. 1 and table 1, when the reverse driven gear W9 is engaged with the first output shaft 2 by the first shift device GS1 and when the first input shaft 1 rotates in reverse input power, the multi-speed overdrive module MF is in the third forward speed state. At this time, the power of the first input shaft 1 is transmitted to the first output shaft 2 sequentially through the reverse drive gear P9, the reverse driven gear W9, and the first shift device GS1, and the speed ratio r1 between the first input shaft 1 and the first output shaft 2 is — Z6/Z3. Namely, when the first input shaft 1 reversely rotates to input power, the first output shaft 2 normally rotates to output power.

When the first driven gear W1 is engaged with the first output shaft 2 under the action of the first gear shift device GS1, by controlling the forward input power and the reverse input power of the first input shaft 1, or by controlling the forward movement trend or the reverse movement trend of the first input shaft 1, the first overrunning clutch FC1 and the second overrunning clutch FC2 can be automatically locked and unlocked according to the relative rotation movement or the relative rotation trend of the respective driving part and the driven part, and the multi-gear overrunning transmission module MF can be arbitrarily switched between two forward gears without other control and operation, and the gear shifting process is basically not interrupted without power.

When the reverse driven gear W9 is engaged with the first output shaft 2 by the first shifting device GS1, the first output shaft 2 outputs power in the reverse direction when power is input to the first input shaft 1 in the forward direction, and the first output shaft 2 outputs power in the forward direction when power is input to the first input shaft 1 in the reverse direction.

When the first driven gear W1 is engaged with the first output shaft 2 by the first shift device GS1, the multi-speed overdrive module MF has a function of unlocking the forward rotation and locking the reverse rotation of the first output shaft 2, that is, the first output shaft 2 is freely locked in the forward rotation and locked in the reverse rotation.

In addition, since the multi-gear overdrive transmission module MF is provided with the first shift device GS1, the first overrunning clutch FC1 and the second overrunning clutch FC2, when any one of the first shift device GS1, the first overrunning clutch FC1 and the second overrunning clutch FC2 fails, the first output shaft 2 still has the function of outputting power in a forward rotation manner, so that the reliability of the whole transmission module is greatly increased.

(13) When the multi-gear overrunning transmission module MF is in the fourth forward gear state, the reverse driven gear W9 is first disengaged from the fourth transmission shaft 4 under the action of the third shifting device GS3, then the reverse driven gear W9 is engaged with the fourth transmission shaft 4 under the action of the third shifting device GS3, and the multi-gear overrunning transmission module MF can be switched from the fourth forward gear state to the fifth forward gear state after the first input shaft 1 is controlled to be switched from reverse rotation to forward rotation, but there is inevitable power interruption during gear switching due to the absence of the overrunning clutch during gear switching.

When the multi-gear overrunning transmission module MF switches between the first forward gear, the second forward gear, the third forward gear and the fourth forward gear, except for controlling the clutch state corresponding to the shift device GS, the first overrunning clutch FC1 and the second overrunning clutch FC2 can be automatically locked and unlocked by controlling the forward input power and the reverse input power of the first input shaft 1 or controlling the forward movement trend or the reverse movement trend of the first input shaft 1 according to the relative rotational movement or the relative rotational movement trend of the respective active part and the passive part, and the multi-gear overrunning transmission module MF can be switched between the adjacent gears without power without other control and operation, and the gear shifting process is basically interrupted without power.

When the multi-gear overrunning transmission module MF is in the first forward gear, the second forward gear, the third forward gear and the fourth forward gear, the multi-gear overrunning transmission module MF has a reverse rotation locking function and a forward rotation unlocking function on the first output shaft 2, so that the first output shaft 2 is ensured to rotate freely in the forward direction and rotate in the reverse direction.

In addition, since the multi-gear overdrive transmission module MF is provided with the first shifting device GS1, the second shifting device GS2, the third shifting device GS3, the first overrunning clutch FC1 and the second overrunning clutch FC2, when any one of the shifting devices GS or any one of the overrunning clutches FC fails, even when any two of the shifting devices GS and the overrunning clutches FC fail, the first output shaft 2 still has the function of outputting power in a forward rotation mode, so that the reliability of the whole transmission module is greatly improved.
