Abstract
The utility model discloses a powdery plate of friction plate of clutch. The flat faces of the two ends of the circular powdery plate 3 are distributed with rhomb-shaped grooves 1. The utility model is characterized in that square grooves 2 are arranged on the rhomb-shaped grooves 1 on the one end face or two end faces of the powdery plate 3; The square grooves 2 and the center circle of the powdery plate 3 are arranged in a symmetrical structure. The four corners of the square groove 2 are positioned on the circumference the powdery plate 3. The powdery plate can satisfy the coordinate torque-transmission capability and cause the minimum volume of the friction clutch under the condition of a certain operating oil pressure though the working surface of the friction plate is small.
Description
Technical field:
The utility model relates to a kind of friction plate, in particular for the powder sheet of the clutch friction plate in the mechanical transmission.
Background technique:
As everyone knows, friction clutch is to come transferring power by the friction plate in the clutch, and friction plate comprises mating plate and powder sheet, and their interfolded are in clutch housing.Wherein the both ends of the surface of mating plate are smooth surface, are distributed with groove on the both ends of the surface of powder sheet, and powder sheet groove commonly used has radial groove, spiral chute, arc water chestnut shape groove, spiral to add radial groove.The effect of groove is: (1) makes cold oil rapidly by working surface, takes away heat; (2) when friction plate engages, destroy oil film, improve friction factor, to improve torque transmission capacity; (3) store certain lubricant oil, friction plate each several part temperature is evenly distributed.Under the certain situation of operating oil pressure, the work area of friction plate is big more, and torque transmission capacity is just big more, but the volume of clutch also increases the also corresponding increase of weight thereupon.In order to satisfy the requirement in market, must satisfy under the condition of torque transmission capacity, design a kind of clutch body that can make and amass as far as possible little friction plate.
The model utility content:
The purpose of this utility model provide a kind of certain at operating oil pressure, and can satisfy under the situation of torque transmission capacity, make the powder sheet of the clutch friction plate of friction clutch volume minimum, fundamentally solve the volume problem of friction clutch.
The purpose of this utility model is achieved in that a kind of clutch friction plate powder sheet of design, on circular powder sheet end flat, be distributed with water chestnut shape groove, its key is: the end face of powder sheet or the water chestnut shape groove of both ends of the surface are provided with square groove, square groove becomes symmetrical structural configuration with the center of powder sheet, and four corners are on the circumference of powder sheet.
The powder chip architecture that the utility model adopts arc water chestnut shape groove and square groove to combine can better be stored certain lubricant oil, and friction plate each several part temperature is evenly distributed.Select the rhombus oil groove for use, burst effect is preferably arranged, a large square groove is set on water chestnut shape groove helps to store more lubricating oil, can more effectively take away abrasive dust, improve the oil clearance state between the powder sheet, improve friction factor, arrange performance to improve powder sheet glue, thereby improve the transmitting torque ability of friction plate greatly.
The beneficial effects of the utility model are: under the certain situation of operating oil pressure, though the working surface of friction plate is little, but still can satisfy equal torque transmission capacity, and make the volume minimum of friction clutch.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment:
Please see Figure 1, Fig. 2, the powder sheet of clutch friction plate described in the utility model is to be distributed with water chestnut shape groove 1 on the plane at the two ends of circular powder sheet 3, and the end face of powder sheet 3 or the water chestnut shape groove 1 of both ends of the surface are provided with square groove 2, square groove 2 becomes symmetrical structural configuration with the center of powder sheet 3, and four corners are on the circumference of powder sheet 3.
The live width of water chestnut shape groove 1 described in the utility model is 0.5mm, and the degree of depth is 0.3mm; The groove width of described square groove 2 is 6mm, and groove depth is 0.5mm.Described powder sheet material adopts SMCu-1, has the stronger ability of bearing heat load.
