With the increasing automobile reserves, the carbon emissions of vehicles put a great strain on the environment, and the great demand for petroleum also raises petroleum safety issues. China is still a large country with imported petroleum, and the dependence of petroleum on imported petroleum is as high as more than 50%. Aiming at the increasingly severe national fuel consumption limit standard, each part generating power consumption needs to be optimally designed, so that the power consumption is reduced, and the fuel consumption of the whole vehicle is further reduced.
At present, the floating caliper disc brake is widely applied to passenger vehicles and commercial vehicles, and the friction plates cannot return timely after the vehicles are braked each time in the driving process, so that the brake discs and the friction plates continuously contact and rub to generate dragging torque, the driving resistance of the whole vehicle is increased, and the fuel economy of the vehicle is influenced. According to the measurement and calculation, the dragging moment of the calipers is reduced by 1N.m, the side force of four wheels of the whole vehicle can be reduced by about 12N in total, the oil consumption can be reduced by 0.1-0.15L/100Km, and the electric vehicle can increase the endurance mileage by about 3 Km. Therefore, various main engine plants seek low-drag calipers and even zero-drag calipers so as to improve the economy of the whole automobile. The dragging torque of the current common calipers is about (3.5-5.0) N.m, and the dragging performance can be further reduced through the structure optimization design.

Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the caliper friction plate active return spring structure is arranged between a friction plate back plate 1 and a brake caliper body bracket 5; the structure of the return spring is a return spring piece 3, the return spring piece 3 is an arched elastic piece, one end of the arched elastic piece is fixed on the brake caliper body support, the other end of the arched elastic piece is fixed on the friction plate back plate, and an S-shaped elastic piece structure a is arranged on the arched elastic piece between the top of the arched elastic piece and the friction plate back plate.
The utility model discloses calliper friction disc initiative return spring structural design is novel, and resilience elasticity is stable, and the effect stroke is long to and the resilience is rapid, thereby realize the friction disc return rapidly, effectively reduce the braking and drag stagnate.
One end of the return spring piece 3 is fixed on the brake caliper body bracket through a detachable fixing screw 4; the other end of the return spring piece is fixed on the back plate of the friction plate through a rivet 2; the assembly and disassembly are convenient, and the replacement operation of the friction plate is facilitated.
The top of the arched elastic sheet is of a straight sheet structure b; the end part of the return spring piece is provided with a flanging, and each end of the return spring piece is fixed through the flanging.
The friction plate back plate 1 is provided with a friction plate lug part, and the other end of the return spring piece is fixed on the friction plate lug part. The force is direct and uniform, no deflection moment exists, the return effect is better than that of a common splayed return spring, and the dragging reduction performance is more obvious.
The utility model discloses well return spring leaf one end riveting is in friction disc backplate ear, and the other end passes through the fix with screw on calliper support, makes the friction disc receive the pulling force that breaks away from the brake disc direction all the time. The structure realizes the active quick return of the friction plate after braking and the separation of the friction plate from the brake disc, and can effectively reduce the dragging by 1-2 N.m.
After the automobile brake is released, the ear parts of the friction plates are pulled back to the initial positions along the ear guide grooves of the caliper body support under the action of the resilience force of the spring pieces, so that the friction plates are separated from the brake disc, and the dragging torque is further reduced. The spring piece has long rebound stroke, and can provide stable rebound force in the whole life cycle of the friction plate along with the abrasion of the friction plate.
The spring force of the spring plate consists of two parts: the straight piece provides resilience force similar to a plate spring; and secondly, the stretching resilience force provided by the S-shaped sheet. The resilience force of the spring leaf directly acts on the ear part of the back plate of the friction plate after braking each time, and the friction plate is pulled back along the guide groove of the ear part; because the resilience force directly acts on the ear part of the friction plate, the resilience efficiency is very high. The structure of special design provides elasticity by straight portion and S type part simultaneously, provides bigger elastic working stroke in less space, has guaranteed the reliable return in the whole wearing and tearing cycle of friction disc, and calliper keeps low dragging performance all the time.
