Description
Technical Field
The utility model relates to a transmission equipment specifically is a dry-type separation and reunion initiative piece for among the automatic gearbox.
Background
With the rapid development of industrial technology in China, the automatic transmission has higher requirements in China. However, because the multi-gear automatic transmission has a small volume and a large heat capacity at the time of high-power input, the heat capacity limit is quickly reached, and the dry clutch driving plate in the automatic transmission is a key component of the automatic transmission, the dry clutch driving plate needs to have better performance and longer service life. Because the production technology is strictly blocked in countries such as the United states, Germany, Japan and the like, the products in China at present have the following defects:
1. the friction material loss is large in the production process, the forming process is complex, the assembly is complicated, and the precision is low;
2. the driving sheet is meshed with the rotating shaft through a single key, so that large torque cannot be transmitted, and the driving sheet has low meshing precision, large abrasion and low dynamic and static friction coefficients;
3. the heat dispersion is poor, and the heat can not be effectively discharged in time, so that the service life is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the above-mentioned background art, providing a dry-type separation and reunion active plate among automatic gearbox, this dry-type separation and reunion active plate should have that forming process is simple, power passes the characteristics that the square ability is strong, long service life and environmental protection and energy saving.
The technical scheme of the utility model is that:
a dry clutch driving plate in an automatic transmission comprises an annular special-shaped metal framework and annular friction layers arranged on the end surfaces of two sides of the special-shaped metal framework; the method is characterized in that: a plurality of trapezoidal teeth which are circumferentially arranged are manufactured on the outer circumferential surface of the special-shaped metal framework; the end surfaces of the two sides of the special-shaped metal framework are respectively provided with a plurality of strip-shaped grooves which are circumferentially arranged; and the binding surface of the friction layer is provided with a convex block matched with the strip-shaped groove.
The number of the trapezoidal teeth is 8-16.
And two symmetrical trapezoidal teeth of the special-shaped metal framework are provided with positioning clamping grooves.
The utility model has the advantages that:
the utility model discloses can not produce the waste material in process of production, have the energy-concerving and environment-protective effect that is showing, simultaneously torsion transmission ability is strong, the meshing precision is high, the sound friction coefficient is than little, frictional behavior is stable, high temperature resistance can be strong, therefore the product wear resistance has all obtained the promotion, has effectively prolonged life.

Fig. 2 is a left side view structure diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in fig. 1, a dry clutch driving plate in an automatic transmission includes an annular shaped metal frame 1 (preferably, a steel frame) and an annular friction layer 2.
The outer circumferential surface of the special-shaped metal framework is provided with a plurality of trapezoidal teeth 3, the outer sides of the trapezoidal teeth are arc surfaces 3.1, grooves 4 are formed between the trapezoidal teeth, and the two trapezoidal teeth which are symmetrically arranged are also provided with positioning clamping grooves 5. Trapezoidal tooth is the rectangle spline tooth, and rectangle spline tooth quantity generally is 8 ~ 16, and with the utility model discloses the system has the interior key tooth that corresponds with the rectangle spline tooth in the complex axis of rotation, compares with conventional structure and is showing and has improved cooperation precision and power transmission ability.
The special-shaped metal framework is characterized in that the end faces of two sides of the special-shaped metal framework are also respectively provided with a plurality of strip-shaped grooves 6 which are circumferentially arranged, and the number of each strip-shaped groove is 10-15. The friction layers are respectively arranged on the end faces of the two sides of the special-shaped metal framework, and the thickness of the friction layers is generally 1.0-1.5mm (preferably 1.2 mm). And a binding surface (the surface facing the special-shaped metal framework) of the friction layer is provided with a convex block, and the convex block and the strip-shaped groove are mutually riveted.
The utility model discloses in process of production, need mediate the raw materials mixing of frictional layer earlier, and extrusion moulding technology and mould frock are kneaded with frictional layer hot briquetting on special-shaped metal framework (the lug of filling in the bar groove is formed simultaneously on the binding face of frictional layer) with the even agent of rethread interpolation, compare with traditional shaping mode of pasting, have improved production efficiency by a wide margin.
