Abstract
The invention relates to a fast synchronization device of an automotive mechanical transmission, which comprises an automotive transmission assembly and the fast synchronization device, wherein the fast synchronization device is mounted on the transmission through a power take-off window of the transmission of the automotive transmission assembly, and a gear transmission device in the fast synchronization device is meshed with a gear of an intermediate shaft of the transmission; and an engaging and disengaging gear for linkage and disconnection of auxiliary power is used for linking the gear transmission device with an auxiliary power linkage device through a common shaft, and the auxiliary power linkage device is linked with the auxiliary power. The fast synchronization device can fast lead the rotational speed of a change gear to be consistent with that of an output shaft during the gear shift process, thereby achieving the purpose of lightweight gear shift after synchronization, greatly protecting a synchronizer, greatly raising the service life and the capacity of the synchronizer and having the advantages of compact structure, small volume and a wide range of applications.
Description
Technical field
The invention belongs to the automotive transmission technical field, relate in particular to a kind of fast synchronization device of automotive mechanical transmission.
Background technique
Make input and output reach the purpose of light gear shift synchronously by synchronizer mostly during existing automobile-used mechanical transmission gear shift.Synchronizer mainly is to lean on the friction torque of cone of friction to make change gear consistent with the output shaft rotating speed, to reach synchronous back gear shift.Cone of friction is easy to wear, used for buses speed changer particularly, and synchronizer is the most fragile, and on the AMT automatic transmission, the synchronous capacity of synchronizer also is the widely used major reason of restriction automatic transmission.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind ofly have compact structure, volume is little and the fast synchronization device of automotive mechanical transmission of advantage applied widely.
The present invention solves the technological method that its technical problem adopts: a kind of fast synchronization device of automotive mechanical transmission, comprise automotive transmission assembly and fast synchronization device, fast synchronization device is installed on the speed changer by the force taking window of speed variator mouth of automotive transmission assembly, gear drive in the described fast synchronization device and the engagement of the countershaft-gear of speed changer; Auxiliary power connects and the engaging and disengaging gear of disconnection links together gear drive and auxiliary power coupling arrangement by common shaft, auxiliary power coupling arrangement and auxiliary power link, when gear shift, by the speed discrepancy of sensor to input and output, sending instruction allows auxiliary power that the input shaft power train of a power to speed changer is provided, this moment, engine power separated with speed changer by clutch, therefore auxiliary power makes its change gear consistent with the output shaft rotating speed, plays synchronous effect fast.
Described gear drive, engaging and disengaging gear and auxiliary power coupling arrangement all are installed on the housing of fast synchronization device.
Described gear drive, auxiliary power connect with the engaging and disengaging gear and the auxiliary power coupling arrangement that disconnect makes an integral body.
The invention has the beneficial effects as follows: in gearshift procedure, can make change gear consistent fast with the output shaft rotating speed; to reach the purpose of the synchronous light gear shift in back; greatly protect synchronizer, the life-span of synchronizer and capacity are improved greatly, have compact structure, volume advantage little and applied widely.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1-automotive transmission assembly, 2-gear drive, 3-engaging and disengaging gear, 4-auxiliary power coupling arrangement.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Referring to Fig. 1, a kind of fast synchronization device of automotive mechanical transmission, comprise automotive transmission assembly 1 and fast synchronization device, fast synchronization device is installed on the speed changer by the force taking window of speed variator mouth of automotive transmission assembly, and the gear drive 2 in the described fast synchronization device meshes with the countershaft-gear of speed changer; Auxiliary power connect with the engaging and disengaging gear 3 that disconnects by common shaft with gear drive 2 and auxiliary power coupling arrangement 4(or claim auxiliary power source) link together, wherein gear drive 2, engaging and disengaging gear 3 and auxiliary power coupling arrangement 4 all are installed on the housing of fast synchronization device.
Usually, gear drive 2, auxiliary power connect with the engaging and disengaging gear 3, the auxiliary power coupling arrangement 4 that disconnect can make an integral body, and auxiliary power coupling arrangement 4 links with auxiliary power, and auxiliary power just is provided when needs; When gear shift, by the speed discrepancy of sensor to input and output, sending instruction allows auxiliary power that the input shaft power train of a power to speed changer is provided, this moment, engine power separated with speed changer by clutch, therefore auxiliary power can make its change gear consistent with the output shaft rotating speed, plays synchronous effect fast.
The present invention can make change gear consistent with the output shaft rotating speed in gearshift procedure fast; to reach the purpose of the synchronous light gear shift in back; greatly protect synchronizer; the life-span and the capacity of synchronizer are improved greatly; solve a conventional machinery formula speed-changer synchronizer rapid wear and the synchronous not enough difficult problem of capacity well, also solved the problem of AMT automatic transmission fast slewing.
