Description
Technical field
The utility model relates to a kind of transmission clutch, relates in particular to a kind of clutch core covering device that is applicable to Motor Vehicle.
Background technique
So-called clutch, as the term suggests utilize in other words " from " an amount of power transmitted with " closing ".Clutch is one of core component of Motor Vehicle power-transmission system, can realize separation and the combination of transmission of power.Generally speaking, Motor Vehicle adopts friction clutcch, formed by friction plate, steel disc, central sleeve, compression spring, platen, bolt, lift slab and pto, it is between motor and gearbox, the moment that is used for storing on the engine flywheel passes to gearbox, to guarantee that vehicle passes to an amount of driving force of driving wheel and moment of torsion under different running condition, belong to the category of power assembly.
Its working principle is to realize the Normally closed type friction driving of friction plate and steel disc between platen and the central sleeve by the elastic force of cylindrical compression spring, Driving force on acting on lift slab greater than the compression spring elastic force the time, lift slab promotes platen and moves axially, axial no impacting force between friction plate and steel disc, friction driving is thrown off the realization transmission of power and is separated, otherwise, then produce impacting force, realize transmission of power.
In each accessory of clutch, the number of the diameter of the intensity of platen spring, the friction factor of friction plate, clutch, the position of friction plate and clutch is the key factor that determines the clutch performance.The rigidity of spring is more big, and the friction factor of friction plate is more high, and the diameter of clutch is more big, and the clutch performance is also just more good.
There is following problem in the clutch core cover in the prior art:
(1) elasticity of cylindrical spring is linear, and in use there is tired decay in the elastic force of cylindrical spring, when elastic force is decayed, the axial positive pressure that acts between friction plate and steel disc also reduces thereupon, and the moment of torsion that friction driving can be transmitted is proportional with axial positive pressure, therefore, the friction torque between friction plate and steel disc is also along with reducing, thereby reduced the load capacity of clutch;
(2) there is fretting wear all the time in the friction driving between steel disc and friction plate, behind friction plate and steel disc wearing and tearing attenuate, has been equivalent to reduce the compression height of compression spring, has namely reduced the impacting force of compression spring to friction plate and steel disc, and then has reduced friction torque;
(3) when the friction torque between steel disc and friction plate was lower than the maximum moment of motor at this place, friction plate and steel disc were in slipping state always, fault such as friction plate can occur this moment and steel disc is ablated, and it is unable to climb.
The model utility content
At above technical problem, the utility model improves the clutch core covering device, has invented a kind of resilient beam, wear-resistant, long service life, reliability is high and clutch core covering device simple in structure.
In order to realize above goal of the invention, the technological scheme that the utility model provides is, a kind of clutch core covering device, comprise platen, friction plate, steel disc, central sleeve, dish spring, disc spring pad, bolt, lift slab, be provided with the butterfly elastic element between described central sleeve and the lift slab, the dish elastic element comprises dish spring and disc spring pad, and in the dish spring one end centering cover heavy stand hole, the other end contacts with lift slab by disc spring pad.
Further, described platen cooperates by tooth with central sleeve and is slidingly connected, and platen can move axially along the central sleeve tooth.
Further, described lift slab connects by bolton with platen, and friction plate and steel disc are crisscross arranged between platen and central sleeve, and steel disc can move axially along the central sleeve tooth.
By the improved clutch core covering device that the utility model provides, reduced clutch friction torque decay in use, reduced the wearing and tearing of elastic member, improved working life and the reliability of clutch.
Description of drawings
Fig. 1 is the structural representation of the clutch core covering device that provides of the utility model.
Wherein, reference character is: the 1-platen; The 2-friction plate; The 3-steel disc; The 4-central sleeve; 5-dish spring; The 6-disc spring pad; The 7-bolt; The 8-lift slab.
Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is done further detailed, clear, complete explanation, meet novelty, creativeness and the practicability that Patent Law requires fully with explanation the utility model.What should be noted that embodiment describes is a part of mode of execution of the present utility model, can not be used for restriction protection domain of the present utility model.
As shown in Figure 1, the utility model provides a kind of clutch core covering device, comprises platen 1, friction plate 2, steel disc 3, central sleeve 4, dish spring 5, disc spring pad 6, bolt 7, lift slab 8.Platen 1 and central sleeve 4 cooperate by tooth and are slidingly connected, and platen 1 can move axially along the central sleeve tooth; Lift slab 8 and platen 1 be by 7 fastening connections of bolt, friction plate 2 and steel disc 3 staggered placing between platen 1 and the central sleeve 4, and steel disc 3 can move axially along the central sleeve tooth, is provided with the butterfly elastic element between central sleeve 4 and the lift slab 8.Described dish-shaped elastic element comprises dish spring 5 and disc spring pad 6, and dish spring 5 one end centerings overlap in the 4 heavy stand holes, and the other end contacts with lift slab 8 by disc spring pad 6.
Because the dish spring has the change stiffness characteristics, can in certain deformation band, keep elastic force basicly stable, therefore, when wearing and tearing attenuate in friction plate and the steel disc using process, the dish spring can remain unchanged substantially to the axial positive pressure of friction plate and steel disc, thereby reduced the decay of friction torque, reduced the wearing and tearing of elastic member, improved working life and the reliability of clutch.
