Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] see figure 1 , figure 2 , a pushing mechanism for a disc brake, including a rotating ring 1, a pushing ring 7 and a guide bracket 4; the pushing ring 7 is provided with a friction plate 10. The pushing mechanism is coaxially installed between the brake disc of the disc brake and the actuating mechanism. The actuating mechanism drives the rotating ring 1. There can be one or more actuating mechanisms, and multiple actuating mechanisms can provide greater input. force; the form of the actuating mechanism can be diversified, and the rotating ring 1 can be directly driven by an electric motor. Generally, a ring gear 3 is arranged inside the rotating ring 1 , and one or more actuating mechanisms transmit input force to the rotating ring 1 through gear meshing with the ring gear 3 , so that the rotating ring 1 rotates around the a...

Abstract
A pushing mechanism for a disc brake comprises a rotating ring (1), a pushing ring (7) and a guiding support (4), wherein a plurality of spiral oblique planes (2) are arranged on the rotating ring (1); bosses (12) which correspond to the spiral oblique planes (2) are arranged on the pushing ring (7); the number of the bosses (12) are equal to that of the spiral oblique planes (2); a roller (6) is mounted on each boss (12) through a hinge pin I (8); the spiral oblique planes (2) are in contact with the rollers (6) on the corresponding bosses (12) in a matched manner; a plurality of guiding rollers (9) are mounted on an inner ring of the pushing ring (7) through hinge pins II (11); guiding grooves (5) which correspond to the guiding rollers (9) are formed in the external circumference of the guiding support (4); the number of the guiding grooves (5) is equal to that of the guiding rollers (9); the guiding grooves (5) are straight grooves or spiral grooves; and the guiding rollers (9) are assembled in the corresponding guiding grooves (5) and can move in the direction of the grooves. An input rotating torque is converted into an axial clamp force, so that an axial output force is enlarged by a few of times.
Description
technical field [0001] The invention relates to a pushing mechanism, more specifically to a pushing mechanism for disc brakes, and belongs to the technical field of disc brakes. Background technique [0002] At present, disc brakes used in the automotive field generally drive a pushing mechanism through air pressure or hydraulic pressure to generate brake clamping force. The pushing mechanism in the existing disc brakes can usually only push a friction plate with a limited area, and there is generally only one such pushing mechanism in each disc brake; therefore, compared to the entire brake disc, the thrust effect The points are not evenly distributed. Therefore, when the vehicle is braked under heavy load, it is difficult for the friction lining with limited area to bear the heat energy generated by braking, which seriously affects the service life of the friction lining, which in turn will lead to a series of impacts such as cracking and slag falling of the friction lini...
