Background technology
As shown in Figure 1, the oil cylinder 1 that detects the device of disc brake braking moment in the prior art is fixed, and the normal pressure of 2 pairs of brake discs 3 of brake shoe is N, and the power that dish spring 4 is subjected to is that (K is a dish spring elasticity coefficient to Kx; X is a dish spring decrement), the pressure that piston 5 is subjected to is PA, (P is the pressure of oil, and A is a piston area).
After oil pressure reduced, brake shoe 2 pasted brake disc 3 gradually.Be attached to the card of brake disc 3 fully when brake shoe 2 after, suppose that this moment, dish spring 4 decrements were x
0, ignore the suffered friction force of piston 5, then have:
N＝Kx
0-PA
Because brake shoe 2 has been attached to card, so along with oil pressure reduces, x
0No longer change.By following formula, piston 5 areas, dish spring elasticity coefficient and dish spring 4 decrements when pasting card can record in advance and can regard definite value as.Different like this oil pressure P is just corresponding with different N, just can obtain N indirectly as long as record oil pressure.Brake shoe 2 is a definite value with the friction factor f of card, and N and f multiply each other and just obtain friction force, and then obtain braking moment.
But said method must record K and x in advance
0Because brake shoe 2 is wearing and tearing in actual state, that is to say x
0It can not be a definite value.In addition, owing to make, the elasticity coefficient K of each dish spring 4 is also inequality, and the elasticity coefficient of different decrement correspondences changes in a certain scope, and this has just brought very mistake to the measurement of braking moment.
This shows that prior art needs further improvement and develops.
