Abstract
Disclosed is a bidirectional driving plate for a sun wheel of an automatic transmission. The bidirectional driving plate is characterized in that the bidirectional driving plate is formed by four 30-degree equant one-way tooth symmetric arrays, one 60-degree equant one-way tooth symmetric arrays and two fixing holes.
Description
Technical field:
The present invention relates to electric automobiles, particularly a kind of automatic transmission sun gear bi-directional drive plate.
Background technique:
For solving the motor automatic transmission of electric vehicle patent No., be 201120027552.3 to be applied to the bidirectional driving apparatus of electro-tricycle, electric vehicle.
China's patent 201020523498.7 being hereby incorporated by discloses electric vehicle transmission sun gear bi-directional drive fixed plate, this technology is because a whole assembly connects gearbox and sun gear, the sun gear that causes speed changer is fixed on a point at work all the time, radially with directly to without free activity space, in service and speed changer produces friction, cause gearbox heating, noise is large, no load current is high, cannot meet the requirement of operation.
In China's patent 201120040062.7 being incorporated herein by reference a bit, two-way driving disc for motor automatic transmission of electric vehicle is disclosed, this technology adopts on two-way slab and slots, the cylinder of two-way dish coordinates location with groove, this technology has solved the part defect of aforementioned patent technology, but it is high to make precision prescribed, slightly error can generation current increases, and shortens the electric motor car ability that continues.
Conventionally, at work, along with motor speed and sense of rotation are made diverse location directly to motion, planetary reducing gear has free activity space to speed changer, and need to be in equilibrium position in order to avoid produce friction with transmission shaft.
Summary of the invention:
The inventor recognizes and utilizes 1 the 60 symmetrical and adjacent unidirectional tooth of degree decile of unidirectional teeth work 120 degree of a kind of four 30 degree deciles to make symmetrical Throwing thing alignment internal diameter extension, with the ratchet close fit on drive plate, form bidirectional driving apparatus, in work, by ratchet, make the balance to speed changer, realize lower running current.
A kind of automatic transmission sun gear of the present invention bi-directional drive plate, as shown in Figure 1 and Figure 2, is characterized in that driving plate is comprised of four 30 unidirectional tooth 1 symmetric arrays of degree decile, unidirectional tooth 2 symmetric arrays of 60 degree decile, two fixed holes 3.
In one form, driving plate is made by being greater than metal board laser cutting or the punching press that 3.5mm is thick.
An embodiment of a kind of automatic transmission sun gear of the present invention bi-directional drive plate, has 3, two fixed holes 3 of two fixed holes to coordinate with gearbox on driving plate, with screw, connect firmly gearbox.
Further, in driving plate, there is the adjacent and symmetric arrays of four 30 unidirectional teeth 2 of the degree unidirectional tooth 1 of decile and one 60 degree decile, form irregular reciprocity gear ring.
Further, the tooth direction that the described 30 degree unidirectional teeth 1 of decile and 60 are spent the unidirectional tooth 2 of decile is in the same way.
Further, the described unidirectional tooth 2 of 60 degree decile, connects with Throwing thing line on the limit of four 30 unidirectional tooth 1 symmetries of degree decile.
Further, 60 degree decile unidirectional tooth 2 Throwing thing lines should be offset to internal diameter, on any point of the unidirectional tooth 2 Throwing thing line face of 60 degree decile from distance of center circle from be all less than 1, the unidirectional tooth of 30 degree decile from distance of center circle from.
In one form, as shown in Figure 3, unidirectional tooth 2 parts of 60 degree decile have symmetrical groove 5, and the column 6 of drive plate coordinates with groove 5 centerings, the spacing reverse-drive that realizes of time slot 5 column 6 of reversing gear.
A kind of automatic transmission sun gear of the present invention bi-directional drive plate, be applied to gear ring initiatively, planet wheel is driven, sun gear is fixing automatic transmission, as shown in Figure 2, when the screens of the deep-seated of two symmetrical ratchets 4 and driving plate is put angle, vehicle is done direction of advance operation, another two ratchets 4 coordinate with 1, the unidirectional tooth of 30 degree decile of one of them symmetry of driving plate, the balance of modified speed changer radial motion; When electric power order is reversed, drive plate is done the reversing motion of former direction, and ratchet 4 is given up the throne backward, blocks 2, the unidirectional tooth of 60 degree decile, realizes driving plate and drive plate and forms two-way clutch.
Accompanying drawing explanation:
Fig. 1 is a kind of automatic transmission sun gear bi-directional drive plate plan view;
Fig. 2 is the schematic diagram of working between driving plate and drive plate;
Fig. 3 is the unidirectional tooth fluting of the 60 degree decile schematic diagram of driving plate.
Embodiment:
The invention discloses a kind of automatic transmission sun gear bi-directional drive plate, as shown in Figure 1 and Figure 2, it is characterized in that driving plate has 3 one-tenth of four 30 degree decile unidirectional tooth 1 symmetric arrays, unidirectional tooth 2 symmetric arrays of 60 degree decile, two fixed hole groups.
In one form, driving plate is made by being greater than metal board laser cutting or the punching press that 3.5mm is thick.
An embodiment of a kind of automatic transmission sun gear of the present invention bi-directional drive plate, has 3, two fixed holes 3 of two fixed holes to coordinate with gearbox on driving plate, with screw, connect firmly gearbox.
Further, in driving plate, there is the adjacent and symmetric arrays of four 30 unidirectional teeth 2 of the degree unidirectional tooth 1 of decile and one 60 degree decile, form irregular reciprocity gear ring.
Further, the tooth direction that the described 30 degree unidirectional teeth 1 of decile and 60 are spent the unidirectional tooth 2 of decile is in the same way.
Further, the described unidirectional tooth 2 of 60 degree decile, connects with Throwing thing line on the limit of four 30 unidirectional tooth 1 symmetries of degree decile.
Further, 60 degree decile unidirectional tooth 2 Throwing thing lines should be offset to internal diameter, on any point of the unidirectional tooth 2 Throwing thing line face of 60 degree decile from distance of center circle from be all less than 1, the unidirectional tooth of 30 degree decile from distance of center circle from.
In one form, as shown in Figure 3, unidirectional tooth 2 parts of 60 degree decile have symmetrical groove 5, and the column 6 of drive plate coordinates with groove 5 centerings, the spacing reverse-drive that realizes of time slot 5 column 6 of reversing gear.
Technician is appreciated that, can comprise that data make suitable adjustment to disclosed configuration without departing from the invention, the example unrestricted object for example only as described above, recognizing of it will be apparent to those skilled in that do not changing in aforesaid operations situation, can enter very little modification and reach identical object configuration or mounting process, the present invention be restricted by claims.
