Abstract
Disclosed is a vehicle full-automatic transmission used in motor vehicle transmission system. The transmission comprises one input shaft gear and a group of output shaft gear having different size and tooth number, wherein all the gears are helical gears. The helical gear has axial component force, the input shaft gear can move left and right under the function of the axial component force, and the input shaft gear can also drive an input shaft supporting plate to move up and down together under the function of a variable speed gear lift force and a return spring pulling force. The transmission can automatically change the engage position of the input shaft gear on the output shaft gear according to the driving resistance o the motor vehicle on different road conditions so as to generate suitable speed and torque to achieve the purpose that the motor vehicle can run normally on different road conditions.
Description
Technical field
The present invention is used for motor vehicle powertrain, and its integral body is transmission assembly.
Background technique
At present, vehicular transmission all will be used automatically controlled, hydraulics, could realize automatic speed changing.
Summary of the invention
For make vehicular transmission safer, work reliably, this type of speed changer has saved complicated electricity, hydraulic control system technology, has realized mechanical automatic speed-changing, and its structure is greatly simplified.
The technical solution adopted for the present invention to solve the technical problems is: the gear in this speed changer is angular gear, utilizes the axial thrust load of angular gear and the reaction force of return spring to work.(as Fig. 1) wherein on the input shaft three shelves gears concentric with axle, speed change tooth and axle decentraction, speed change tooth and one, second gear or two, three-range transmission crown are equal, have at least two teeth axially to overlap like this, mesh with the output shaft gear full-depth tooth all the time during input shaft gear work.Input shaft axially can seesaw, and and the output shaft supporting plate move up and down together, input shaft gear can be according to output shaft resistance size, drives axial direction positioning device and input shaft supporting plate and selects operation one, two, between three-range transmission.The gear edge boss is a back-up ring, and its effect is when input shaft gear has only two teeth to overlap the position when automobile shifts up, just can move right.
The invention has the beneficial effects as follows application machine automatic Transmissions Technique, simple structure, easy-maintaining and maintenance, full-depth tooth engagement, reliable operation.So it is the life-span is long, and cheap for manufacturing cost.

1. output shafts among Fig. 1,2. output shaft bearing, 3. one, second gear speed change tooth, 4. two, three class gear shift tooth, 5. input shaft gear, 6. one grade of gear, 7. intermediate gear, 8. three-range transmission, 9. input shaft, 10. axial return spring, 11. one grade of axially locating raceway groove, 12. second gear axially locating raceway groove, 13. third gear axially locating raceway grooves, 14. axial direction positioning devices, 15. transmission shaft universal joint, 16. bearing of input shaft, 17. input shaft supporting plates, 18. downward return springs, 19. third gear locating slot, 20. the second gear locating slot, 21. 1 grades of locating slots, locating stud, spring assembly about in the of 22..
Embodiment
In Fig. 1, Engine torque is added on the input shaft gear (5) by transmission shaft, universal joint (15), and input shaft (9) does not move under the effect of navigation system (14), and moment of torsion passes on the output shaft (1) by three-range transmission (8).
1. subtract retaining: output shaft (1) is when resistance increases to certain value, the axial thrust load of helical teeth will be broken away from third gear axially locating raceway groove (13), input shaft gear (5) will be to left movement, simultaneously compressional axis is to return spring (10), and input shaft gear (5) enters into two by overlapping tooth, three class gear shift tooth (4).Speed change tooth (4) decentraction, to break away from positioning device (22) up and down, draw high downward return spring (18) simultaneously, when input shaft gear (5) is lifted to second gear coincidence position, second gear locating slot (20) arrives positioning device (22) locking, and input shaft gear (5) continues under the effect of axial thrust load toward moving left, when parallel with intermediate gear (7), axial direction positioning device (14) arrives second gear axially locating raceway groove (12), is locked on the second gear.Because the inertia of navigation system, under the output shaft resistance of certain limit, speed changer will keep dynamic balancing.If output shaft (1) resistance continues to increase, dynamic balancing was lost efficacy, and input shaft gear (5) will repeat said process, enter one grade of operation.
2. shift up: in the time of one grade, reduce as output shaft (1) resistance, under the effect that input shaft return spring (10) and helical teeth axial thrust load reduce, axial direction positioning device (14) ejects from one grade of location raceway groove (11), and input shaft gear (5) will be through one, second gear speed change tooth (3) enters intermediate gear (7).Positioning device (22) ejects from one grade of locating slot (21) under the pulling force of return spring (18) up and down simultaneously, input shaft supporting plate (17) down moves, in second gear locating slot (20) locking, under certain limit output shaft resistance, speed changer will operate on the second gear always.If at this moment output shaft (1) resistance continues to reduce, two indexer dynamic balancing were lost efficacy, and input shaft gear (5) will be through two, three class gear shift tooth (4) enters third gear, move in third gear.
3. backset: increase locking mechanism in speed changer navigation system (14) (22), can realize that gear is locked.
Claims (3)
1. this fully-automatic gearbox for vehicle has an input shaft gear and one group of size and the different output shaft gear of the number of teeth, is angular gear.Both cooperatively interact, and produce three different speed and moment of torsion, and it is characterized in that: output shaft gear is a hierarchic structure, and wherein three shelves gears are concentric with axle, two speed change teeth and a decentraction.During work, input shaft gear drive axle and positioning device are done axially and are seesawed, and move up and down together with the input shaft supporting plate.
2. according to the described automatic transmission of claim 1, it is characterized in that: moving up and down and axially seesawing during input shaft work can be used with transmission shaft universal joint, movable spline.
3. according to the described automatic transmission of claim 1, it is characterized in that: the two-stage automatic speed changing structure that lorry uses.
