Description

Technical Field

[0001] This invention relates to the field of brake technology, and more particularly to motor gear brakes. Background Technology

[0002] Existing air disc brakes typically rely on external force to drive a lever arm through the air chamber during vehicle braking. For example, patent application CN118705300A discloses "a clearance compensation mechanism for an air disc brake," which requires the air chamber to provide power during braking, resulting in insufficient braking force on heavily loaded and downhill sections. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a motor gear brake that addresses the above-mentioned technical deficiencies, thereby solving the problem of insufficient braking force in the prior art under heavy loads and on downhill sections.

[0004] The technical solution adopted in this invention is: to provide a motor gear brake, including a brake body, wherein a brake pad assembly of the brake body moves closer to a brake disc, the brake body includes a lever arm, the lever arm is inside a caliper body, characterized in that the end of the lever arm has a transmission gear, and further includes: A motor is located on the outside of the clamp body, and the output end of the motor has a reduction mechanism. The transmission mechanism, wherein the output end of the reduction mechanism is transmitted to the transmission gear through the transmission mechanism, is used to drive the lever arm to swing.

[0005] To further optimize this technical solution, the transmission mechanism includes: A bevel gear is disposed at the output end of the reduction mechanism; The disc gear is rotatably mounted inside the clamp body; A spur gear is coaxially arranged with the disc gear, and the spur gear meshes with the transmission gear to drive the lever arm to swing.

[0006] To further optimize this technical solution, the reduction mechanism is a planetary gear reduction module.

[0007] To further optimize this technical solution, the axis of the motor is parallel to the direction of movement of the brake pad assembly.

[0008] The beneficial effects of this invention are as follows: 1. The motor achieves low-speed, high-torque output through a reduction mechanism, thereby improving braking force.

[0009] 2. The motor is controlled by a circuit, resulting in fast output and shorter braking response time. Attached Figure Description

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0013] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0014] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0015] like Figure 1-4As shown, the motor gear brake includes a brake body 1, with a brake pad assembly 101 moving close to a brake disc 102. The brake body 1 includes a lever arm 2 within a clamping body 103, with a transmission gear 201 at the end of the lever arm 2. It also includes a motor 3 disposed outside the clamping body 103, with a reduction mechanism 4 at the output end of the motor 3; and a transmission mechanism 5, the output end of which is connected to the transmission gear 201 via the transmission mechanism 5 to drive the lever arm 2 to swing.

[0016] The transmission mechanism 5 includes: a bevel gear 501, disposed at the output end of the reduction mechanism 4; a disc gear 502, rotatably disposed within the clamp body 103; and a spur gear 503, coaxially disposed with the disc gear 502, and meshing with the transmission gear 201, for driving the lever arm 2 to swing.

[0017] The deceleration mechanism is a planetary gear deceleration module.

[0018] The axis of the motor 3 is parallel to the direction of movement of the brake pad assembly 101.

[0019] In use, the motor 3 is mounted on the outside of the clamp body 103 through the reduction mechanism 4. The reduction mechanism 4 adopts a planetary gear reduction module, which has the advantages of high transmission efficiency, compact structure and large transmission ratio. The output end of the motor 3 is connected to the input end of the reduction mechanism 4, and the output end of the reduction mechanism 4 is fitted with a bevel gear 501 as the driving wheel.

[0020] When braking is required, motor 3 provides braking power, which is reduced in speed and increased in torque by reduction mechanism 4. Bevel gear 501 rotates, driving disc gear 502 to rotate. Disc gear 502 is coaxial with spur gear 503. Disc gear 502 drives spur gear 503 to rotate, which in turn drives transmission gear 201 to move, thereby driving lever arm 2 to swing. After lever arm 2 swings, the force is converted into a parallel thrust, which ultimately achieves braking (the braking effect achieved by lever arm 2 swinging is existing technology).

[0021] The transmission gear 201 is arc-shaped and meshes with the spur gear 503.

[0022] When applying the parking brake, a backup power supply can be used to control the motor 3 to stop in the braking state, thereby achieving the parking brake.

[0023] The brake body 1 also has a brake clearance adjustment device, which can adjust the brake clearance.

[0024] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
