Description

Technical Field

[0001] This utility model relates to the field of transmission lead screw technology, and in particular to an EMB electromechanical braking transmission lead screw. Background Technology

[0002] Braking by steerable systems are electronically controlled braking systems. Currently, braking systems can be divided into three types. The main braking by steerable systems studied at home and abroad are electro-hydraulic braking (EHB) systems, electro-mechanical braking (EMB) systems, and hybrid braking by steerable systems (HBBW). Electro-mechanical braking (EMB) systems are a modern vehicle braking technology that combines the advantages of electric drive and mechanical braking to achieve efficient, precise, and sensitive braking performance.

[0003] The EMB system mainly consists of a motor, reducer, clamping device, lead screw, caliper, and controller. However, the lead screw in the EMB system can only be connected to a specific motor. If the motor and lead screw are not the same size when the system is being repaired, other connecting equipment needs to be purchased to connect the motor and lead screw, which affects work efficiency.

[0004] Therefore, the existing EMB electromechanical brake transmission lead screw can only be connected to specific motors. If the replacement motor and the lead screw are of different sizes during system maintenance, other connecting equipment needs to be purchased to connect the motor and the lead screw, which affects work efficiency. Therefore, an EMB electromechanical brake transmission lead screw can be designed. By rotating the knob, three displacement blocks on the rear end face of the connecting seat are displaced. The bottom end of the displacement block is equipped with a clamping block, which is an arc block. This facilitates the connection of the lead screw body to the output end of servo motors of different diameters, improving the applicability of the device. Utility Model Content

[0005] To overcome the problem that existing EMB electromechanical brake transmission screws can only be connected to specific motors, and that if the replacement motor and transmission screw are of different sizes during system maintenance, other connecting equipment needs to be purchased to connect the motor and transmission screw, thus affecting work efficiency.

[0006] The technical solution of this utility model is as follows: an EMB electromechanical brake transmission screw, including a screw body, a connecting seat at the rear end of the screw body, a displacement block at the rear end of the connecting seat, a displacement groove at the front end of the displacement block located on the rear end face of the connecting seat, the front end of the displacement block extending to the inner side of the displacement groove, a clamping block at the bottom end of the displacement block, a transmission rod at one side of the displacement block located on the inner side of the displacement groove, and a transmission disc at the bottom end of the transmission rod located on the inner wall of the displacement groove.

[0007] Preferably, the three displacement blocks on the rear end face of the connecting seat are displaced by rotating the knob, and the bottom end of the displacement block is provided with a clamping block, which is an arc block, so as to facilitate the connection between the lead screw body and the output end of servo motors of different diameters and improve the applicability of the device.

[0008] Preferably, the lead screw body and the connecting seat are integrated into one structure.

[0009] Preferably, the bottom end of the clamping block is an arc block.

[0010] Preferably, there are three displacement blocks, and the number of transmission rods is the same as the number of displacement blocks.

[0011] Preferably, gears are provided at the intersections of the upper and lower ends of the transmission rod with the displacement block and the transmission disc, respectively.

[0012] Preferably, a toothed block is provided on one side of the transmission rod on the outer side of the displacement block, and the transmission rod meshes with the displacement block and the transmission disc respectively through gears.

[0013] Preferably, one of the transmission rods has a knob at the front end of the outer end face of the connecting seat, and the transmission rod and the knob are an integral structure.

[0014] The beneficial effects of this utility model are:

[0015] The transmission lead screw rotates by turning a knob at one end of the connecting seat. The knob drives one of the transmission rods to rotate, and the transmission rod meshes with the displacement block and the transmission disc through gears. This causes the displacement block to move inside the displacement groove through the other transmission rods. The bottom end of the displacement block is equipped with a clamping block, which is an arc block. This facilitates the connection of the lead screw body with the output end of servo motors of different diameters, improving the applicability of the device. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an EMB electromechanical braking transmission screw, including a screw body 1, a connecting seat 2 at the rear end of the screw body 1, the screw body 1 and the connecting seat 2 are an integral structure, a displacement block 3 at the rear end of the connecting seat 2, a displacement groove 5 at the front end of the displacement block 3 located on the rear end face of the connecting seat 2, the front end of the displacement block 3 extending to the inner side of the displacement groove 5, a clamping block 4 at the bottom end of the displacement block 3, the bottom end of the clamping block 4 being an arc block, a transmission rod 7 at one side of the displacement block 3 located on the inner side of the displacement groove 5, and a transmission disc 8 at the bottom end of the transmission rod 7 located on the inner wall of the displacement groove 5, thereby facilitating the connection of the screw body 1 to the output shaft of the servo motor through the connecting seat 2;

[0023] Please see Figures 2-3 In this embodiment, there are three displacement blocks 3, and the number of transmission rods 7 is the same as that of displacement blocks 3. Gears are provided at the intersections of the upper and lower ends of the transmission rods 7 with the displacement blocks 3 and the transmission disk 8, respectively. A toothed block 6 is provided on one side of the transmission rod 7 on the outer side of the displacement block 3. The transmission rod 7 meshes with the displacement blocks 3 and the transmission disk 8 through the gears, thereby driving the transmission disk 8 to rotate through one of the transmission rods 7. The transmission disk 8 meshes with the three transmission rods 7, and the transmission rods 7 are connected to the displacement blocks 3 through transmission, thereby driving the displacement blocks 3 to move inside the displacement groove 5 through the transmission rods 7.

[0024] Please see Figures 3-4 One of the transmission rods 7 has a knob 9 located at the outer end face of the connecting seat 2 at its front end. One of the transmission rods 7 and the knob 9 are an integral structure, and the knob 9 is rotated to drive one of the transmission rods 7 to rotate.

[0025] When the lead screw body 1 needs to be connected to the output shaft of the servo motor during operation, the knob 9 at one end of the connecting seat 2 is rotated. The knob 9 drives one of the transmission rods 7 to rotate. The transmission rod 7 meshes with the displacement block 3 and the transmission disk 8 through gears. Thus, when one of the transmission rods 7 drives the transmission disk 8 to rotate, the other transmission rods 7 drive the displacement block 3 to move inside the displacement groove 5. The bottom end of the displacement block 3 is provided with a clamping block 4, which is an arc block. This facilitates the connection of the lead screw body 1 with the output end of servo motors of different diameters, improving the applicability of the device.

[0026] Through the above steps, rotating the knob 9 causes the three displacement blocks 3 on the rear end face of the connecting seat 2 to move. The bottom end of the displacement block 3 is provided with a clamping block 4, which is an arc block. This facilitates the connection of the lead screw body 1 with the output end of servo motors of different diameters, improves the applicability of the device, and solves the problem that the existing EMB electromechanical brake transmission lead screw can only be connected to specific motors. If the replacement motor and the transmission lead screw are inconsistent in size during system maintenance, other connection equipment needs to be purchased to connect the motor and the transmission lead screw, which affects work efficiency.
