Description

Technical Field

[0001] The invention relates to the field of automobile braking systems, and in particular to a quick-install anti-loosening brake disc. Background Art

[0002] The brake disc is a key component in the car's braking system. When the brake pedal is pressed, the piston in the master brake cylinder is pushed, and pressure is built up in the brake oil circuit. The pressure is transmitted to the brake cylinder piston on the brake caliper through the brake oil. The piston of the brake cylinder then pushes the brake pad to clamp the brake disc, causing friction between the brake pad and the brake disc to reduce the wheel speed and achieve car deceleration or parking, for example:

[0067] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when installing the brake disc 2, its inner ring is inserted into the plug post 43 and pressed in the direction of the transmission shaft 1, and each plug block 32 on the disc body 31 is plugged into the slot 313 on the brake disc 2, a pair of slots 33 are opposite to a pair of fan-shaped flip bodies 411, and then the slot-shaped control device 42 makes each fan-shaped flip body 411 flip around the rotating axis into the slot 33, until one side with the installation slot 412 is pressed against the inner end of the slot 33, and the other side wall of the fan-shaped flip body 411 is pressed against the control device 42, and each torsion spring 413 is deformed to store elastic potential energy, thereby completing the installation of the brake disc 2;

[0068] When removing the brake disc 2, the operation control device 42 is moved away from each fan-shaped flip body 411, and each torsion spring 413 releases elastic potential energy, pushing each fan-shaped flip body 411 to flip around the corresponding rotating axis and disengage from the corresponding slot 33. Then, the brake disc 2 can be pulled away from the transmission shaft 1 until it is disengaged from the plug 43, thereby completing the action of removing the brake disc 2.

[0069] Embodiment 2:

[0070] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the control device 42 includes a floating shell 421, which is slidably installed in the transmission cavity 44, with the inner end closed and a return spring 422 provided between the inner end of the transmission cavity 44; a pair of spiral grooves 423, which are arranged on the peripheral wall of the transmission cavity 44, and both ends have deep grooves 424; a pair of floating clamping members 5, which are respectively movably installed on the peripheral wall of the floating shell 421, slidingly cooperate with each spiral groove 423, and can be inserted into the corresponding deep groove 424, and the longitudinal cross-section of the inner cavity of the floating shell 421 is hexagonal.

[0071] Furthermore, the floating engaging member 5 includes an insert hole 51, which is arranged on the side wall of the floating shell 421; a sliding block 52, which is slidably installed in the insert hole 51 and has a transverse groove 53 at the inner end; an inner groove 54, which is arranged in the inner cavity of the floating shell 421; a flip rod 55, the middle part of which is movably installed in the inner groove 54 through a hinge shaft, one end of which is transmission-coordinated with the transverse groove 53 through a transmission block, and an elastic member 56 is provided between the other end and the bottom surface of the inner groove 54.

[0072] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to remove the brake disc 2, an inner hexagonal wrench is inserted into the inner end of the inner cavity of the floating shell 421. During the process, the inner hexagonal wrench contacts the end of each flip rod 55 away from the insertion hole 51 with the inner hexagonal wrench, and each flip rod 55 is pushed to flip around the corresponding hinge shaft, so that the transmission block at this end of each flip rod 55 slides in the corresponding transverse groove 53, and at the same time, each sliding block 52 is pulled to slide into the inner cavity of the floating shell 421. After each flip rod 55 completely enters the corresponding inner groove 54, the outer end of each sliding block 52 also disengages from the deep groove 424 at the outer end of the corresponding spiral groove 423. Then, the inner hexagonal wrench is rotated to drive the floating shell 421 to rotate, and each sliding block 52 slides from the outer end of the corresponding spiral groove 423 to the inner end of the spiral groove 423. During this process, the floating shell 421 slides toward the inner end of the transmission cavity 44, and after each sliding block 52 is in contact with the corresponding The deep groove 424 at the inner end of the spiral groove 423 corresponds to the deep groove 424. Keeping the angle of the hexagonal wrench, pull it out from the inner cavity of the floating shell 421 along the axial direction of the transmission shaft 1 until the hexagonal wrench is released from the release of each flip rod 55. Each elastic member 56 (which can be an air bag, a spring or a rubber column) releases elastic potential energy to push each flip rod 55 to flip around the corresponding hinge shaft, one end of which extends into the inner cavity of the corresponding floating shell 421, and the other end moves into the insertion hole 51 together with the corresponding transmission block, and each transmission block slides in the corresponding transverse groove 53 and pushes each sliding block 52 to insert into the deep groove 424 at the inner end of the corresponding spiral groove 423. At this time, the floating shell 421 is separated from the contact with each fan-shaped flip body 411. Under the action of the corresponding torsion spring 413, each fan-shaped flip body 411 is separated from the corresponding slot 33. The brake disc 2 can be removed from the plug 43 by simply pulling it away from the transmission shaft 1.

[0073] When installing the brake disc 2, its inner ring is put on the plug post 43 and pressed in the direction of the disc body 31 until the inner surface of the brake disc 2 abuts against the adjacent surface of the disc body 31, and each fan-shaped flip body 411 corresponds to the corresponding slot 33, and then an inner hexagonal wrench is used to insert the inner end of the inner cavity of the floating shell 421. During the process, the inner hexagonal wrench and the end of each flip rod 55 away from the insertion hole 51 are in contact with the inner hexagonal wrench, and each flip rod 55 is pushed to flip around the corresponding hinge shaft, so that the transmission block at this end of each flip rod 55 slides in the corresponding transverse groove 53, and at the same time, each sliding block 52 is pulled to slide into the inner cavity of the floating shell 421, and each flip rod 55 is completely entered into the corresponding inner groove 54, and the outer end of each sliding block 52 is also separated from the deep groove 424 at the inner end of the corresponding spiral groove 423, and then rotated ( The floating shell 421 can be rotated by using an inner hexagonal wrench (which can also be rotated without rotation), and each sliding block 52 slides toward the outer end of the corresponding spiral groove 423. The reset spring 422 releases its elastic potential energy at the same time, and cooperates to push the floating shell 421 to slide out of the transmission chamber 44. During the sliding process of the floating shell 421 out of the transmission chamber 44, it contacts the side plates of the fan-shaped flip bodies 411 that are not provided with the mounting groove 412, and pushes each fan-shaped flip plate to flip around the corresponding rotating shaft until it is inserted into the corresponding slot 33. Each torsion spring 413 is deformed to store elastic potential energy, and then the floating shell 421 continues to slide out of the transmission chamber 44 until the side walls of the fan-shaped flip plates that are not provided with the mounting groove 412 contact the outer wall of the floating shell 421, thereby completing the installation of the brake disc 2 and locking each fan-shaped flip plate.
