The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The invention will now be described in further detail by way of specific examples of embodiments in connection with the accompanying drawings.
Example 1
Referring to fig. 1-6, a transmission is provided in accordance with a first embodiment, including a main housing 100, a torque converter housing 200, and a magnet 300.
Wherein, the main housing 100 is provided with a protrusion 110, the protrusion 110 is located at the circumference side of the differential gear 400, and the protrusion 110 is located below the oil surface of the working oil in the main housing 100.
The protruding portion 110 is provided with a receiving groove 111 with an opening facing the torque converter housing 200, the magnet 300 is clamped in the receiving groove 111, and one side of the magnet 300 facing the torque converter housing 200 is abutted against the torque converter housing 200.
Analysis of the structure of the above-described transmission revealed that: the torque converter mainly comprises a main housing 100, a torque converter housing 200 and a magnet 300, wherein a protruding part 110 is arranged on the main housing 100, and a containing groove 111 for containing the magnet 300 is also formed on the protruding part 110.
The specific connection mode and the position relation of the structure are analyzed as follows: since the accommodation groove 111 is opened toward the torque converter housing 200, the magnet 300 can be smoothly placed in the accommodation groove 111 before the main housing 100 and the torque converter housing 200 are sealed; at this time, by abutting the magnet 300 against the torque converter case 200 on the side facing the torque converter case 200, the magnet 300 can be caught in the accommodation groove 111 of the projection 110, and the magnet 300 can be prevented from being removed from the Rong Nacao.
Further, in order to enable the magnet 300 to be in contact with the working oil, the protrusion 110 is disposed below the oil level of the working oil in the main housing 100 so that the magnet 300 located in the receiving groove 111 of the protrusion 110 can be located in the working oil in order to adsorb the scrap iron mixed in the working oil. Because the working oil near the differential gear 400 flows at a high speed under the high-speed rotation of the differential gear 400, the protrusion 110 may be disposed at the peripheral side of the differential gear 400, so that the magnet 300 may be disposed in the working oil with a relatively large flow rate, thereby increasing the efficiency of absorbing the scrap iron and further reducing the damage of the scrap iron to other components with high cleanliness requirements.
Therefore, the transmission provided by the first embodiment can adsorb scrap iron in the working oil in the shell, and reduce the damage of the scrap iron to other parts with high cleanliness requirements.
Example two
Referring to fig. 1 to 6, a transmission is provided in the second embodiment, and the technical structural relationship of the transmission in the first embodiment is adopted; for example: the second embodiment provides a transmission including a main housing 100, a torque converter housing 200, and a magnet 300; wherein, the main housing 100 is provided with a protruding part 110, the protruding part 110 is located at the circumference side of the differential gear 400, and the protruding part 110 is located below the oil surface of the working oil in the main housing 100; the protruding portion 110 is provided with a receiving groove 111 with an opening facing the torque converter housing 200, the magnet 300 is clamped in the receiving groove 111, and one side of the magnet 300 facing the torque converter housing 200 is abutted against the torque converter housing 200.
The transmission provided in the second embodiment has the same main structure as the transmission in the first embodiment; however, the transmission provided in the second embodiment also relates to a specific structural design. The second embodiment is different from the first embodiment in that: the transmission in the second embodiment has more specific structural characteristics for a specific structure; for example: technical features are added and the specific structures of the main housing 100, torque converter housing 200, and magnet 300 are further defined.
The specific structure and technical effects related to the technical scheme of the second embodiment are as follows:
in order to enable more working oil to be within the adsorption range of the magnet 300 to increase the adsorption effect of the magnet 300 on the iron filings in the working oil, the magnet 300 is provided to protrude from the top of the receiving groove 111; without the influence of the walls of the accommodating groove 111, the volume of the working oil that can be acted on by the protruding portion of the magnet 300 is increased, and the natural adsorption effect becomes better.
Further, referring to fig. 2, a groove 210 is opened in the torque converter housing 200, which is open toward the main housing 100, and the groove 210 is communicated with the accommodating groove 111, so that the volume of the working oil in the adsorption range of the magnet 300 is further increased, and the adsorption effect of the magnet 300 on the iron filings in the working oil is increased.
In addition, since the differential gear 400 can drive the working oil to flow at a high speed, in order to increase the flow speed of the working oil at the position where the magnet 300 is located, the opening of the groove 210 on the torque converter housing 200 is also opposite to the gear tooth portion of the differential gear 400.
Further, referring to fig. 4 and 6, an auxiliary groove 112 is further opened in the protruding portion 110, which opens toward the torque converter housing 200, and one end of the auxiliary groove 112 communicates with the receiving groove 111, and the other end penetrates the protruding portion 110.
The working oil may flow to the magnet 300 through the auxiliary groove 112 during the high-speed movement, or may flow out from the magnet 300 through the auxiliary groove 112 during the high-speed movement, so that the replacement frequency of the working oil contacting with the magnet 300 is increased, and the adsorption efficiency of the iron filings in the working oil is improved.
Further, the protrusion 110 is disposed at the bottom of the main housing 100, which is convenient for design and also convenient for adjusting the positions of other structures in the main housing 100.
Preferably, in order to reduce abrasion of the magnet 300 due to impact of the working oil moving at high speed, a cylindrical magnet is used for the magnet 300; meanwhile, the bottom surface of the magnet 300 is disposed in parallel with the axis of the differential gear 400, so that the working oil moving at high speed will impact more on the cylindrical surface of the magnet 300 when passing the magnet 300, so that the magnet 300 suffers less wear.
Further, the cylindrical surface of the magnet 300 is brought into contact with the torque converter case 200, and the utilization ratio of the magnet 300 can be increased.
Preferably, the edges of the magnet 300 are rounded to further reduce wear to which the magnet 300 is subjected.
Further, the surface of the receiving groove 111 is provided as a smooth surface to reduce wear suffered by the magnet 300 when rotating in the groove, while also allowing the magnet 300 to easily rotate in the groove so that every position of the magnet 300 can be utilized.
Preferably, as an embodiment, the face of the protrusion 110 facing the differential gear 400 is provided so as to guide the oil splashed from the teeth of the differential gear 400 to the guide face 113 of the main reduction gear 500.
The guide surface 113 on the protruding portion 110 can send the working oil to the position of the main reduction gear 500 when the differential gear 400 moves at a high speed.
In addition, the protrusion 110 is disposed below the oil level of the lubricating oil in the main housing 100, so that the lubricating oil splashed at the liquid level by the high-speed movement of the differential gear 400 can be flushed toward the main reduction gear 500 along the guide surface 113, the occurrence of large-scale splashing of the lubricating oil at the liquid level is effectively reduced, the working oil reaching the main reduction gear 500 is increased, and the lubrication effect from the working oil obtained by the main reduction gear 500 is better.
Because the protrusion 110 can divide the lubricant on two sides, the differential gear 400 mainly acts on the lubricant on one side of the protrusion 110 near the differential gear 400, reducing the volume of the lubricant impacted, and further effectively reducing the white foam at the liquid level.
Example III
Correspondingly, referring to fig. 1 and 3, a third embodiment of the present invention provides an automobile, which includes the transmission (the specific structure of the transmission is not described in detail) of the second embodiment, and further includes a differential gear 400; the differential gear 400 is located between the main housing 100 and the torque converter housing 200 of the transmission.
Obviously, the automobile provided by the third embodiment has all the advantages of the transmission because the transmission is included, can adsorb scrap iron in the working oil in the shell, and reduces the damage of the scrap iron to other parts with high cleanliness requirements.
In summary, the embodiment of the invention discloses a transmission and an automobile, which overcome a plurality of technical defects of the traditional transmission. The transmission and the automobile provided by the embodiment of the invention can adsorb the scrap iron in the working oil in the shell, and reduce the damage of the scrap iron to other parts with high cleanliness requirements.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
