The dual-fork shaft type reversing mechanism comprises a retainer ring, a reversing plate, a bracket and a connecting bolt, wherein the retainer ring is fixedly connected with the connecting bolt; and the reversing plate and the bracket are sleeved on the connecting bolt. The dual-fork shaft type reversing mechanism for a transmission can be used for a dual-fork shaft type transmission, and the space utilization rate inside the transmission is further improved.
Description
Technical field
The utility model relates to a kind of device of automotive transmission technical field, specifically is a kind of two fork shaft formula reversing mechanisms that are used for speed changer.
Background technique
Current; Six grades of overdirve gears of domestic use are light, the compact car speed changer; Its gearshift mechanism adopts four fork shafts to add four shift fork structures usually; Shifting gear is arranged by R, 1/2,3/4,6/5 order, and five grades is direct high, has five or six grades of the steering gears that a level is placed with respect to ground in the operating mechanism.Such arrangement of mechanism, declutch shift shaft quantity is many, and processing and assembly technology are numerous and diverse, and it is big to make that operating mechanism takies the FCL space, does not meet current car load lightweight, the requirement of low energy consumption.The utility model adopts that five or six grades of conversion equipments are vertical to be installed with respect to ground level, and five or six grades of shifting blocks, five or six grades of shift forks are fixed on the fork shaft, and all the other shift forks sky respectively are enclosed within on second fork shaft; Reduced the fork shaft usage quantity; Simplified the processing and the assembly technology of operating mechanism, saved simultaneously FCL the space, alleviated the weight of assembly, energy saving more in the car load running process; Meet excelsior design concept, more possess nature affinity comparatively speaking.
Literature search through to existing technology is found; One Chinese patent application 200820120273.X, open day 2009-3-18 has put down in writing a kind of " the two fork shaft formula operating mechanisms of automotive transmission "; This technology contains two shift fork fork shafts; R retaining guide block, R retaining shift fork are fixed on first fork shaft, and all the other shift forks sky respectively overlap or are fixed on first fork shaft or second fork shaft, and all the other shift forks are provided with the gearshift shifting block except that R retaining shift fork; Make shift fork whole moving or slip on fork shaft through the gearshift shifting block during work, realize gearshift.
But two fork shafts in the above-mentioned technology are for horizontal arrangement, gear conversion equipment also are arranged horizontally side by side; Such structure is lower to utilization of space; The location of shift fork will lean on size and the fork shaft of lock-bit groove on size on the casing, the declutch shift shaft size between the lock-bit groove and shift fork positioning pin hole to come comprehensive the assurance, thereby relates to the more shift fork accurate location in the axial direction that influenced of size; In addition, all the other shift forks are sky and are enclosed within on the fork shaft except that reverse gear, do not have corresponding locating slot on the shift fork, can influence the clear sense of gearshift; The the three, one two, 34,56 grade of shift fork and corresponding guide block are split type, need corresponding component to connect, and have increased the assurance of part number and processing dimension like this, can bring some inconvenience to assembling.
The model utility content
The utility model provides a kind of two fork shaft formula reversing mechanisms that are used for speed changer to the above-mentioned deficiency that existing technology exists, and can be used for two fork shaft formulas and five or six grades of vertical conversions, has further improved the speed changer space availability ratio of inner.
The utility model realizes that through following technological scheme the utility model comprises: back-up ring, Buck Plate, support and connecting bolt, and wherein: back-up ring is fixedly connected with connecting bolt, and Buck Plate and support casing are connected on the connecting bolt.
The section of described Buck Plate is a S font structure.
The top of described Buck Plate is provided with the arcuation groove.
Described support is provided with through hole, and the shape of the lower edge of this through hole and arcuation groove is complementary.
Contact between described Buck Plate and the support, the top of Buck Plate and support contact with declutch shift shaft, and the bottom of Buck Plate and pull-fork assembly flexibly connect.
The utility model has been saved the FCL space, has both solved the shift fork orientation problem and has also eliminated the tolerance stack that a plurality of component connections are caused, and has guaranteed clear sense and the accuracy in the gearshift procedure.

Embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technological scheme; Provided detailed mode of execution and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
Embodiment
As shown in Figure 1, this device comprises: back-up ring 1, Buck Plate 2, support 3 and connecting bolt 4, and wherein: back-up ring 1 is fixedly connected with connecting bolt 4, and Buck Plate 2 is socketed on the connecting bolt 4 with support 3.
The section of described Buck Plate 2 is a S font structure, and its top is provided with arcuation groove 5.
Described support 3 is provided with through hole 6, and the shape of the lower edge of this through hole 6 and arcuation groove 5 is complementary.
Contact between described Buck Plate 2 and the support 3, the top of Buck Plate 2 and support 3 contact with declutch shift shaft, and the bottom of Buck Plate 2 and pull-fork assembly flexibly connect.
During the work of this device, stir in the gear shift shifting block notch of each grade shift fork through the gear shift shifting block shift fork moved on fork shaft, with realize, the gearshift function of one two, three fourth gear.Five or six grades of shifting blocks and five or six grades of shift forks are fixed on the declutch shift shaft 2; The gear shift shifting block is stirred in the gear shift shifting block notch of five or six grades of Buck Plates; Making five or six grades of Buck Plate shifting block groove one ends is that direction of middle mind-set is rotated with five or six grades of back-up rings; The shifting block of five or six grades of Buck Plate the other ends rotates in the opposite direction simultaneously; Stir five or six grades of shifting blocks simultaneously, make five or six grades of shifting blocks drive second fork shaft and five or six grades of shift forks move together vertically, to realize five or six grades reverse gear shift function.
