Background
The disc brake has the advantages of good high-temperature resistance under high load, stable braking effect, convenient maintenance and replacement of friction plates and better suitability for braking under severe road conditions, so national regulations actively promote the application of the disc brake in commercial vehicles.
The structure and the principle of the disc brake are as follows: a brake disk is arranged in the middle, and a thrust mechanism is used for pushing the block-shaped friction plates to be pressed to the friction force generated when the brake disk is used for producing, so that the rotating speed of the friction plates is reduced until the friction plates stop, and the vehicle is decelerated or stopped.
At present, the mounting structure of the friction plates of the disc brake at home and abroad is that the friction plates are mounted in a U-shaped groove of a brake support and are in clearance fit, a pressure spring is mounted at the upper end of each friction plate, a pressure plate on the upper end compresses the friction plates on the brake support through the pressure spring, the centrifugal force generated when a brake return or a small brake dragging torque and a brake disc rotate and the up-and-down run-out of the brake normally through a bumpy road surface (the friction plates run-out along with the up-and-down run-out) are considered, and the pressure of the pressure spring needs to be controlled within a certain range: the friction plate is over-jumped up and down to cause noise due to small pressure, and the brake return is not smooth and the dragging torque is large due to large pressure.
Because of frequent braking on a road surface and in normal running, the pressure spring of the friction plate is a plate spring which is subjected to up-down alternating stress, and although the pressure spring is subjected to multiple innovations on materials and processes (such as shot blasting and the like) by the prior art, the pressure spring is easy to break, and the service life of the pressure spring is shorter than that of the friction plate. The failure of the pressure spring can cause the friction plate to be separated from the wheel rim to damage the wheel rim and further cause accidents.
Disclosure of Invention
The utility model provides an elastic pressure spring of a disc brake, which aims to solve the problem that the existing pressure spring is easy to break and prolong the service life of the pressure spring.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides an elasticity pressure spring of disk brake, includes the pressure spring of spring steel material, the whole arc that is of pressure spring, pressure spring both ends symmetry are equipped with the turn-ups, and pressure spring bilateral symmetry is equipped with constant head tank, its characterized in that: the lower surface of the middle position of the pressure spring is fixedly connected with an elastic rubber block.
The improvement of the technical scheme is as follows: arc bulges are arranged on two sides of the elastic rubber block; when the pressing device is used, the arc protrusions on the two sides are guaranteed to be in contact with the friction plate, and the pressing is more reliable.
The improvement of the technical scheme is as follows: the elastic rubber block is connected to the pressure spring in a vulcanization mode; the vulcanization mode is easy to implement and the connection is reliable.
The improvement of the technical scheme is as follows: the radial height from the highest point of the arc bulge of the elastic rubber block to the lower end face of the compression spring is set to be 3-5 mm; thus, the rubber material is saved during implementation, and the due purpose is achieved.
The utility model has the beneficial effects that: the elastic rubber block of pressure spring lower part contacts with the friction disc, and the steel part on upper portion contacts with the clamp plate, and the elastic rubber block has born the upper and lower alternating stress of the overwhelming majority in the use, and axial slip has been guaranteed to the steel part on upper portion, has improved the life who carries the pressure spring by a wide margin.
