Description

Technical Field

[0001] The utility model relates to the technical field of wire-controlled brake systems, in particular to a motor arrangement of an electronically controlled mechanical brake. Background Art

[0002] Electromechanical brakes (EMBs) utilize electric motors to drive the brakes, achieving braking operation. EMBs offer the advantage of integration with other electronic systems and are a mainstream development in the intelligent driving era. However, the actuators and motors of electromechanical brakes are larger than those of traditional EPBs. A high-performance EMB, designed to brake a 3.5-ton passenger vehicle, requires 65 kN of braking force, and the motors are larger than those of conventional EMBs. Traditional electromechanical brake motors are located below the guide pins of the calipers, limiting the actuator's placement angle. This large size and lack of compactness hinder the placement of the EMB assembly near the vehicle's wheel.

[0003] Patent CN218367748U sets a caliper flange and installs the motor on the caliper flange. In this solution, the actuator cannot be separated from the caliper body, the caliper body is difficult to process, and the assembly process is complicated.

[0004] The patented CN220910288U actuator can be separated from the caliper body, but its motor is located below the caliper ear. The caliper ear hole is high, the caliper ear hole arm is too thin, and the strength is difficult to meet durable working conditions. Moreover, since it is not a high-performance EMB, when matching a larger motor, it can no longer be arranged using this solution.

[0005] Therefore, the present application develops a motor arrangement of an electronically controlled mechanical brake to solve the problems existing in the prior art. Utility Model Content

[0006] The utility model aims to provide a motor arrangement for an electronically controlled mechanical brake to solve the problem in the prior art that the caliper body occupies a large space and is not compatible with a small-sized wheel rim, resulting in difficulty in motor arrangement.

[0007] The technical solution of the utility model is: a motor arrangement of an electronically controlled mechanical brake, comprising:

[0008] a caliper body assembly, wherein the caliper body assembly is provided with a through hole;

[0009] An actuator assembly includes a motor, and the motor is located in the through hole. When the motor is installed in the through hole, the actuator assembly is arranged at an angle in two directions of the horizontal plane relative to the horizontal center axis.

[0010] Preferably, the included angle between the central axis of the actuator assembly and the horizontal central axis is -15° to 15°.

[0011] Preferably, the through hole is located between the cylinder hole of the caliper body assembly and the ear hole of the caliper body assembly.

[0012] Preferably, the actuator assembly is detachably mounted on the caliper body assembly.

[0013] Preferably, when the motor is installed in the through hole, an elastic element is provided at the connection position between the motor and the through hole.

[0014] Preferably, the ear hole of the caliper body assembly is a through hole.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) The motor is installed in the through hole, which increases the layout angle of the actuator assembly and can rotate in two horizontal directions. By adjusting the layout angle of the actuator assembly, it can avoid components such as the swing arm drive shaft, which is more conducive to the layout of the EMB assembly on the wheel side;

[0017] (2) The ear holes of the caliper body assembly are through holes, which provide a certain heat dissipation channel, help to reduce the temperature of the caliper body and improve the heat dissipation performance of the brake system;

[0018] (3) An elastic element is provided at the connection position between the motor and the through hole to help the motor reduce vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0026] Traditional electronically controlled mechanical brakes have difficulties in arranging the motor 31, and it is difficult to adapt to the requirements of small-sized rims. In this application, the motor 31 is placed between the cylinder hole 4 and the ear hole 5 of the caliper body assembly 1, and a through hole 2 is opened on the caliper body assembly 1 to accommodate the motor 31, and the through hole 2 can be adapted according to the size and shape of the motor 31, which reduces the arrangement space of the caliper body assembly 1 and provides the possibility of adapting the caliper body assembly 1 to more small-sized rims, solving the problem of difficult arrangement of the motor 31. At the same time, the caliper body assembly 1 needs to be a special part to adapt to different vehicle models, and the EMB actuator of the same specification is a platform part and should be supplied as a separate assembly. In this application, the actuator assembly 3 and the caliper body assembly 1 are detachably connected by bolts, which has better platformization and better processability. It can be assembled by an independent MCU production line, and the finished product can be transported to the caliper body production line and assembled with the caliper body, which has more reasonable processability.

[0027] like Figure 1-Figure 3 The figure shows a motor arrangement for an electronically controlled mechanical brake, comprising a caliper assembly 1 and an actuator assembly 3, which are detachably connected by bolts. The caliper assembly 1 applies force to the brake disc, thereby decelerating and stopping the wheel. The actuator assembly 3 receives control signals and transmits force to the caliper assembly 1 via a drive mechanism, completing the braking action. This detachable connection allows the caliper assembly 1 and actuator assembly 3 to be easily removed for inspection, repair, or replacement in the event of a malfunction or maintenance. This not only improves repair efficiency and reduces maintenance costs, but also allows for flexible combination and configuration based on different vehicle models and braking requirements, reducing the risk of brake failure due to loose or damaged connections, thereby improving the overall reliability of the braking system.

[0028] In this embodiment, Figure 2-Figure 3 As shown, the caliper body assembly 1 is provided with a through hole 2, and the actuator assembly 3 includes a motor 31. The motor 31 is installed in the through hole 2 so that the central axis of the actuator assembly 3 is angled in two directions relative to the horizontal central axis. By installing the motor 31 in the through hole 2, the space can be effectively utilized, so that the entire actuator assembly 3 is more compact in structure. The tilted setting of the actuator assembly 3 in two directions helps to optimize the installation positions of multiple components, reduce space occupancy, and improve the overall compactness and efficiency of the equipment, so that the actuator assembly 3 can be flexibly adjusted within a larger angle range, thereby adapting to different installation angles and working environments, helping to improve the adaptability and versatility of the equipment, so that it can be used in more types of tasks.

[0029] Furthermore, if Figure 4As shown, the angle between the central axis of the actuator assembly 3 and the horizontal central axis is -15° to 15°. By setting the central axis of the actuator assembly 3 to have a certain angle relative to the horizontal central axis and arranging the angle to be greater than 0° at the steering limit, components such as the lower control arm and the drive shaft can be avoided, thereby avoiding malfunction or damage to the equipment during operation, and making it more advantageous to arrange the EMB assembly at the wheel side with more sufficient utilization space.

[0030] Furthermore, the through hole 2 is located between the cylinder hole 4 and the ear hole 5 of the actuator assembly 3. Through the reasonable design and arrangement of the through hole 2, the structural strength of the actuator assembly 3 can be enhanced, which helps to resist the influence of external loads and vibrations on the actuator assembly 3, thereby improving its stability and safety.

[0031] In order to reduce the vibration caused by the brake to the motor 31 when it is in motion, an elastic element is added to the connection position between the two when the motor 31 is installed in the through hole 2, including but not limited to a gasket. The elastic element can effectively absorb the mechanical vibration generated when the motor 31 is running, reduce the impact of the vibration on the equipment itself and the surrounding environment, protect the internal structure of the motor 31, prevent damage or performance degradation caused by vibration, and also compensate for errors caused by manufacturing accuracy, installation errors or relative displacement during operation.

[0032] Furthermore, the ear hole 5 of the caliper body assembly 1 is a through hole. Setting the ear hole 5 as a through hole helps to optimize the heat dissipation performance of the caliper body assembly 1, thereby reducing the temperature of the braking system, maintaining the stability and reliability of the braking system, and improving the braking performance and safety. At the same time, it also enables the caliper body assembly 1 to adapt to different installation requirements.
