Motor with convex structure and motor brake device

Technical Field

The present invention relates to a motor and a motor brake device, and more particularly to a motor and a motor brake device which can be quickly fixed and positioned during assembly.

Background

In response to the driving safety, most of the current vehicles are equipped with an Anti-lock Braking System (Anti-lock Braking System) which is capable of adjusting the Braking action of the wheels, and can adjust the Braking force to avoid the vehicle from losing control due to the deadlock or slip of the tires when the vehicle is driven in an emergency or the road environment is not good.

In general, an anti-lock brake system can adjust braking force in a way of combining and matching software (such as an operation program) and hardware (such as a controller) with a transmission mechanism, so as to enhance the maneuverability of a vehicle under various conditions. However, the hydraulic device for the anti-lock brake system usually has a plurality of components, requires a plurality of processes during assembly, and has a high standard requirement on sealing performance, so welding is a common fitting sealing means.

However, although welding is easy to be performed on complex joint surfaces of components, the welding is not shock-resistant and high-temperature resistant, and the hydraulic device equipped with the motor and the pump can generate shock and hot air during operation, and after a long time, the sealing performance of the components in the hydraulic device is seriously weakened.

The motor, as the main force for driving the hydraulic device, needs to carry a large force, and particularly, stress and vibration are generated during operation, so that the motor needs to be closely arranged in the hydraulic device. The conventional assembly and fixing method is to place the motor into the base and fix the motor in the hydraulic device by using a screw fastening or welding method, but the screw fastening is time-consuming and labor-consuming because of aligning with the screw hole, the welding quality is difficult to control, and the manufacturing cost and the product quality are affected.

The positioning slots 111 of the first setting groove 11 are provided with a number corresponding to the number of the protruding structures 22 of the motor 20, and the protruding structures 22 preferably have directionality to provide guiding, limiting and aligning functions, in other words, the protruding structures 22 having directionality herein are designed to be protruding structures 22, so that the motor 20 can be press-riveted into the body 10 only from a specific direction (e.g., vertically from top to bottom), and once press-riveted, the motor 20 is fastened and is not easily separated from the body 10 and the bearing 90 of the motor 20 is aligned with the brake assembly 40. In one embodiment, the housing 21 of the motor 20 has three protrusions 22 surrounding the outer surface of the housing 21 at equal intervals, and the protrusions 22 are formed by forming protrusions from the inside of the housing 21, but the present invention is not limited to the number and forming manner of the protrusions 22, and the protrusions may be integrally formed with the housing 21 or formed separately and/or attached to the housing 21.

In addition, the first installation groove 11 of the body 10 also has an arc-shaped inner wall for accommodating the motor 20, and the circumference or diameter of the inner wall of the first installation groove 11 is approximately equal to the circumference or diameter of the outer surface of the housing 21 of the motor 20, so that the outer surface of the housing 21 of the motor 20 can be tightly attached to the inner wall of the first installation groove 11 of the body 10. In the embodiment, the body 10 only accommodates the lower half of the motor 20 to position the motor 20, but the present invention does not limit the accommodating space of the body accordingly.

Therefore, when assembling the motor 20 to the body 10, the positions of the protruding structure 22 and the positioning groove 111 are first aligned, the motor 20 is inserted into the first installation groove 11, and then the motor 20 and the body 10 are press-fitted, wherein the press-fitting is preferably performed by interference assembly or interference assembly, and finally the gap between the positioning groove 111 and the upper surface 1011 of the motor 20 and the body 10 is filled to fix the motor 20 in the first installation groove 11. In one embodiment, the body 10 is an aluminum cavity and has a hardness less than that of the housing 21 of the motor 20, and the gap is filled by cutting a notch at the position corresponding to the upper surface 1011 of the protruding structure 22 with a sharp tool, and the material in the notch is drawn toward the housing 21 in response to the force of the sharp tool, so as to fill the gap.

As shown in fig. 6, the third installation groove 17 is located below the first installation groove 11 and has a smaller diameter than the first installation groove 11, and the rotating shaft 23 of the motor 22 penetrates through the rotating element 80 and the bearing 90 located in the third installation groove 17 and brakes the rotating element 80. As described above, part of the bearing 90 is located in the third installation groove 17, and part of the bearing 90 is located in the first installation groove 11, wherein the part of the bearing 90 located in the first installation groove 11 is substantially in contact with the lower surface of the motor 20 and is accommodated in the housing 21 of the motor 20. In detail, the outer surface of the bearing 90 may be divided into an upper half and a lower half, wherein the upper half is closely attached to the inner wall of the housing 21 of the motor 20, and the lower half is closely attached to the inner wall of the third installation groove 17. The bearing 90 can distribute the load applied to the rotating component 80 and the motor 20 when the motor braking device 1 is in operation, and the overall arrangement of the motor 20 and the body 10 can also increase the heat dissipation effect.

Next, an assembly process of the motor brake device according to the embodiment of the present invention will be described. Firstly, the bearing and the rotating component are assembled in a third setting groove in a body provided with a plurality of communicated setting grooves, wherein the bearing and the rotating component are coaxially arranged in the third setting groove in a laminating way, and the bearing is positioned above the rotating component. Because the third setting groove is located first setting groove below and communicates with each other with first setting groove and second setting groove, and bearing and runner assembly and motor have the structure and the interdynamic in the transmission function, consequently in an embodiment, bearing and runner assembly assemble earlier on the motor, then put into in the setting inslot of body in the lump with the motor, nevertheless the utility model discloses do not be the limit according to this.

Then, the motor is assembled in the first setting groove on the upper surface of the body, wherein the first setting groove is provided with a positioning groove for correspondingly accommodating the protruding structure of the motor, therefore, when the motor is assembled on the body, the protruding structure of the motor needs to be aligned to the positioning groove of the first setting groove, and then the motor is inserted into the first setting groove, so that the protruding structure corresponds to the positioning groove. Since the contour of the first setting groove is similar to the shape of the motor, the housing of the motor can closely fit the inner wall of the first setting groove. Then, the gap between the motor and the upper surface of the body and the positioning groove of the first setting groove is filled so as to fix the motor in the first setting groove of the body.

Then, the braking component is assembled in a second setting groove on the first side surface of the body, wherein the second setting groove is communicated with the first setting groove, so that the braking component can be in transmission connection with the motor, and the transmission connection is that the motor is arranged through a component between the braking component and the braking component, for example but not limited to, the bearing and the rotating component drive the rotating component and indirectly drive the braking component to actuate during operation.

Finally, the electronic control unit is assembled to the upper surface of the body, covering the portion of the motor protruding from the upper surface of the body. Thus, the assembly of the motor brake device is completed.
