Description

Friction block assembly with initiative return function

Technical Field

The utility model relates to a friction block assembly matched with a brake disc when being used for an automobile brake, in particular to a friction block assembly with an active return function.

Background

Along with the development of automobile technology, green, low-carbon and energy-saving become the development direction of automobiles, and at present, new energy automobiles become the main research and development and production direction of various large automobile enterprises. However, mileage anxiety of new energy automobiles is a major bottleneck restricting industry development. Through researches, in the running process of the vehicle, the dragging moment of the calipers is overlarge, and the friction blocks and the brake disc generate the dragging phenomenon, so that the vehicle is one of main energy consumption of new energy sources. However, friction blocks are mainly generated by the fact that the friction blocks cannot return in time and are continuously contacted with a brake disc, so that the return capacity of the friction blocks is improved, and the friction block friction is solved, the friction blocks are reduced in dragging, and the vehicle energy consumption utilization rate is improved.

To solve such problems, countermeasures commonly adopted at present are:

method a: the friction block is coated with lubricating grease with higher viscosity at the matching position of the two sides of the friction block and the bracket or the spring piece, so that the return resistance of the friction block is reduced;

method b: the processing capability of the form and position tolerance of the friction block is improved, the disc gap is improved, and the dragging degree of the friction block is reduced;

although the method can improve the dragging of the friction block to a certain extent, the method has larger defects. After the whole vehicle is durable, lubricating grease is easy to dry, so that friction blocks are blocked; the method b improves the machining precision of each part, so that the manufacturing cost of the part is increased, the friction block is deteriorated when the form and position tolerance is newer after being used for a period of time, and the friction is increased continuously.
