Energy-saving electromagnetic clutch

Abstract

The utility model discloses an energy-saving electromagnetic clutch, which belongs to the field of clutches and comprises a driving wheel, a driven wheel connected with the driving wheel through a friction plate and a shell for storing the driving wheel and the driven wheel. Compared with the prior art, the device has the advantages that the electromagnetic telescopic rod pushes the rotating shaft sleeve and the stepped hollow semicircular pushing discs to move inwards, and when the stepped hollow semicircular pushing discs move inwards mutually, a complete circle is formed; as the upper top surface of the driven wheel and the inner circle edge of the stepped hollow semicircular pushing disc are slope surfaces, the upper top surface and the inner circle edge of the stepped hollow semicircular pushing disc cannot be in contact with each other in a normal state, and when the stepped hollow semicircular pushing disc is closed, the upper and lower surfaces of the driven wheel and the stepped hollow semicircular pushing disc are in friction connection; and the stepped hollow semicircular pushing disc can synchronously run along with the electromagnetic telescopic rod, so that the force borne by the electromagnetic telescopic rod is greatly reduced, and the electromagnetic clutch is more energy-saving.

Description

Technical Field

[0001] This utility model relates to the field of clutches, specifically an energy-saving electromagnetic clutch. Background Technology

[0002] When driving a car, in order to better change its speed, a gearbox is usually set behind the engine. The speed is controlled by different gears of the transmitter. However, in order to enable the transmitter to change speed freely, a clutch is usually installed between the engine and the transmitter. With the development of electromagnetic technology, the clutch has gradually developed into an electromagnetic clutch based on electromagnetic induction.

[0003] Existing electromagnetic clutches typically consist of a driving wheel, friction plates, a driven wheel, and a housing. The rotation of the driven wheel is controlled by the connection between the friction plates on the bottom surface of the driven wheel and the driving wheel. To better control the distance between the two, a friction plate release assembly, i.e., an electromagnet composed of electromagnetic coils, is usually installed on one side of the driven wheel. The position of the driven wheel is controlled by the magnetic force of the electromagnet.

[0004] In order to generate the corresponding magnetic force, the power generation device of the friction plate loosening assembly is mostly high-power level. However, the jogging operation of the high-power motor and its power consumption result in a great deal of energy waste during the use of the electromagnetic clutch. Utility Model Content

[0005] The technical problem this invention aims to solve is that current electromagnetic clutches mainly rely on the magnetic force generated by coils to control the engagement and disengagement of the driven wheel, resulting in high power consumption.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an energy-saving electromagnetic clutch, including a driving wheel, a driven wheel connected to the driving wheel via friction plates, and a housing for storing the driving wheel and the driven wheel. A friction plate release assembly is provided on one side of the driven wheel. The friction plate release assembly is located above the driven wheel, along with a set of stepped hollow semi-circular push disks, a rotating bushing sleeve fitted above the stepped surface of the stepped hollow semi-circular push disks, and an electromagnetic telescopic rod threaded through the housing and connected to the outer wall of the rotating bushing sleeve. The upper top surface of the driven wheel and the inner edge of the stepped hollow semi-circular push disks are both sloped surfaces.

[0007] As an improvement, the friction plate is connected to the bottom surface of the driven wheel by high-temperature resistant adhesive, and the top surface of the driven wheel is provided with an internal gear cavity sliding groove.

[0008] As an improvement, the housing is a single-opening structure, and the open end of the housing is provided with a sealing cover for sealing. The sliding groove of the internal gear cavity passes through the sealing cover, and a driven wheel reset assembly for controlling the automatic separation of the driven wheel is provided between the sliding groove of the internal gear cavity and the sealing cover.

[0009] As an improvement, the driven wheel reset assembly includes a T-shaped sliding bushing fitted on the sliding groove of the internal gear cavity and several spring plates welded between the T-shaped sliding bushing and the outer wall of the sealing cover.

[0010] As an improvement, both the electromagnetic telescopic rod and the sealing cover are connected to the housing via bolts.

[0011] As an improvement, the splicing surfaces of the two stepped hollow semicircular push disks are connected by a pin structure.

[0012] The advantages of this invention compared to existing technologies are as follows: This device uses an electromagnetic telescopic rod to push a rotating bushing and a stepped hollow semicircular push disk to move inward. When the stepped hollow semicircular push disk moves inward, it forms a complete circle. Because the upper surface of the driven wheel and the inner edge of the stepped hollow semicircular push disk are both sloping surfaces, they cannot contact each other under normal conditions. However, when the stepped hollow semicircular push disk closes, the upper and lower surfaces of the two surfaces rub against each other, so that when the driven wheel presses down to complete the closure, the stepped hollow semicircular push disk will rotate synchronously. This greatly reduces the force on the electromagnetic telescopic rod, making the electromagnetic clutch more energy-efficient. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] As per the instruction manual Figure 1 , 2As shown in Figure 3, the device includes a driving wheel 1, a driven wheel 3 connected to the driving wheel 1 via a friction plate 2, and a housing 4 for storing the driving wheel 1 and the driven wheel 3. The friction plate 2 is connected to the bottom surface of the driven wheel 3 via high-temperature resistant adhesive, and the top surface of the driven wheel 3 is provided with an internal gear cavity sliding groove 31. The housing 4 has a single open structure, and the open end of the housing 4 is provided with a sealing cover 41 for sealing. The internal gear cavity sliding groove 31 passes through the sealing cover 41. Between the internal gear cavity sliding groove 31 and the sealing cover 41, there is a driven wheel reset assembly 42 for controlling the automatic separation of the driven wheel 3. The driven wheel reset assembly 42 includes a T-shaped sliding bushing 421 sleeved on the internal gear cavity sliding groove 31 and several spring plates 422 welded between the T-shaped sliding bushing 421 and the outer wall of the sealing cover 41. The driven wheel 1 passes through the drive wheel through hole on the bottom surface of the housing 4 and is fixed with a rotary bearing. Similarly, a rotary bearing is fitted on the cylindrical surface of the sliding groove 31 of the internal gear cavity and inserted into the inner hole of the T-shaped sliding bushing 421 for fixing, ensuring that the internal gear cavity sliding groove 31 can be rotated while being affected by the sliding of the T-shaped sliding bushing 421. After inserting the thin cylindrical end of the T-shaped sliding bushing 421 into the center through hole of the sealing cover 41, multiple spring plates 422 are welded to the thick cylindrical surface of the T-shaped sliding bushing 421 and the sealing cover 41, ensuring that the driven wheel 3 is in a non-contact state with the drive wheel 1 under normal conditions. The friction plate 2 is glued to the bottom surface of the driven wheel 3 with high-temperature resistant adhesive, ensuring that the driven wheel 3 can rotate synchronously with the drive wheel 1 after being connected through the friction plate 2.

[0020] As per the instruction manual Figure 2 , 3As shown in Figure 4, a friction plate loosening assembly 5 is provided on one side of the driven wheel 3. The friction plate loosening assembly 5 is located above the driven wheel 3, consisting of a set of stepped hollow semi-circular push disks 51, a rotating bushing 52 fitted above the stepped surface of the stepped hollow semi-circular push disks 51, and an electromagnetic telescopic rod 53 threaded through the housing 4 and connected to the outer wall of the rotating bushing 52. The splicing surfaces of the two stepped hollow semi-circular push disks 51 are connected by a pin structure. The top surface of the driven wheel 3 and the inner edge of the stepped hollow semi-circular push disks 51 are both sloped surfaces. The electromagnetic telescopic rod 53 is connected to the housing 4 by a bolt structure. The output shaft of the electromagnetic telescopic rod 53 passes through the side wall of the housing 4, and screws are used to secure the electromagnetic telescopic rod 53. The bottom surface of the telescopic rod 53 is connected to the outer wall of the housing 4. The stepped hollow semi-circular push disks 51 are respectively fitted onto the rotating shaft sleeves 52 from the cross-section. The pins at the cross-sections of the two stepped hollow semi-circular push disks 51 are then connected to the pin holes. Note that the inclined ends of the inner holes of the two stepped hollow semi-circular push disks 51 correspond to the inclined surfaces of the driven wheel 3, so as to ensure that the discs formed by the stepped hollow semi-circular push disks 51 can rotate synchronously with the driven wheel 3. The output shaft of the rotating electromagnetic telescopic rod 53 is rotated, and the stud at the top of the output shaft is screwed into the screw hole on the side of the rotating shaft sleeve 52 for fixation. This allows the electromagnetic clutch to be closed with minimal force through the electromagnetic telescopic rod 53, saving energy.

[0021] In a specific implementation of this invention, the output shaft of the engine and the input shaft of the gear adjuster are respectively inserted into the connecting keyhole of the drive wheel 1 and the sliding groove 31 of the internal gear cavity. The length of the sliding groove 31 of the internal gear cavity is greater than the effective distance of the clutch. When the electromagnetic telescopic rod 53 receives the output signal, the electromagnetic telescopic rod 53 pushes inward, thereby causing the two stepped hollow semi-circular push disks 51 to close into a complete circle. The inclined surface inside the stepped hollow semi-circular push disk 51 will slide against the inclined surface at the top of the driven wheel 3, thereby driving the spring plate 422, the T-shaped sliding bushing 421 and the driven wheel 3 to press down, so that the friction plate 2 is pressed tightly on the drive wheel 1. This drives the driven wheel 3 to rotate, while simultaneously driving the stepped hollow semi-circular push disk 51 to rotate synchronously around the internal balls of the rotating bushing 52.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
