Description

One-way clutch

This author is about a one-way clutch, especially an innovative one-way clutch designer that can prevent the generation of noise, make it more convenient to use, and has more practical and practical features in its overall application.

According to the current one, the current product is applied to the one-way clutch of the starting mechanism of the motor vehicle, which is a power output end of the starting mechanism of the circular disk body, and the drive shaft is provided with the shaft hole of the circular disk body; When the starting mechanism outputs the rotating power, the one-way clutch is driven to rotate, and the clutch member is driven by the clutch member that is pushed by the elastic force in the circular disk body to drive the engine to start, and the engine starts. After the operation, the speed of the drive shaft of the connecting engine is greater than the speed of the one-way clutch driven by the connecting start mechanism. At this time, the drive shaft compresses the spring through the clutch block and the side of the push block, so that the drive shaft can slide over the clutch block, This prevents engine power from being transmitted back to the starting mechanism.

However, since the one-way clutch uses a clutch member distributed in the circular disk body to provide a clutch mechanism in combination with a pushing block, a spring, and the like, and has many components, the assembly takes time and labor, and the use thereof is in use. In the process of pushing the block and the spring to constantly close and release the clutch block, the spring is stuck, or the spring top abuts against the block, and the friction between the circular disk body and the clutch block is generated. Noise, and will cause the clutch block to wear and reduce the service life of the one-way clutch; plus the one-way clutch must drill an oblique through hole around the circular disk body, and the oblique through hole is angularly The limitation is that only three oblique through holes can be drilled in the periphery of the circular disk body, and more oblique through holes cannot be added to assemble the clutch mechanism composed of the clutch block, the push block and the spring, so that During the transmission process, the load acting on the one-way clutch is only shared by the three clutch blocks, which will cause the problem that the load force of each clutch block is too large.

Therefore, the relevant industry has proposed a clutch, please refer to the "one-way clutch" No. M486707 published on September 21, 2014, which comprises: a circular disk body in which a shaft hole is formed, and a plurality of ring columns are formed. An oblique receiving groove at a periphery of the shaft hole hole, the two ends of the receiving groove are respectively a narrow groove end and a wide groove end; a plurality of permanent magnetic portions are distributed in the circular disk body, and are respectively adjacent to each a narrow groove end of the accommodating groove; and a plurality of clutch members rotatably mounted in each of the accommodating grooves of the circular disk body, the clutch member being a member made of a magnetic conductive material and capable of being The permanent magnetic portion is magnetically moved to the narrow groove end of the accommodating groove.

However, the above-mentioned "one-way clutch" can achieve the expected functions such as simple structure, quick assembly, long service life, and reduced load on the clutch member, but it is also found in its actual operation and use, the structure is in use, due to its The accommodating groove, the permanent magnetic member, and the clutch member in the accommodating groove are disposed on the circular disk body of the passive member, so that during the rotation, the clutch member is circular with the passive member. The rotation of the disc body results in some slight noise, which still leaves room for improvement in the overall structural design.

The reason is that the creators have made this year's experience in the design and development of the relevant industries, and have researched and improved the existing defects to provide a one-way clutch for the purpose of achieving better practical value.

The main purpose of the present invention is to provide a one-way clutch, which is mainly provided in the active part setting accommodating groove for the transmission member, and the transmission member can move the top support passive member when the active member rotates, and the passive member is driven to rotate. When the passive member rotates beyond the rotational speed of the active member, the active member stops rotating to disengage the transmission member from the passive member, so that the passive member does not emit noise during the rotation, so that the active member is used. It is more convenient, and it has more practical and effective features in its overall implementation.

The main purpose and effect of this one-way clutch are achieved by the following specific technical means:

Mainly including active parts, transmission parts and passive parts;

The driving member is driven to rotate by the power source, and a shaft hole is formed in the middle of the driving member, and a plurality of slanting receiving grooves are formed in the periphery of the shaft hole, so that the receiving groove has a narrow end at one end. The other end has a wide end, and the wide end of the corresponding receiving groove is provided with a magnetic member, and each of the receiving grooves is provided with a transmission member, and the active member is coupled with a passive member, under normal conditions. The transmission member is attracted by the magnetic attraction of the magnetic member and is located at the wide end of the accommodating groove. When the active member rotates, the transmission member is moved to the narrow end by the centrifugal force to press the passive member. The positioning is carried out, and the driving member drives the passive member to rotate by using the transmission member.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings:

First of all, please refer to the schematic diagram of the three-dimensional exploded structure of the first drawing and the schematic diagram of the combined sectional view of the second drawing. The creation mainly includes the active part (1), the transmission part (2) and the passive part ( 3); where:

The driving member (1) is driven to rotate by the power source, and a shaft hole (11) is formed in the middle of the driving member (1), and a plurality of oblique housings are formed on the circumference of the shaft hole (11). The slot (12), the accommodating slot (12) can be set to a different number according to different requirements, so that the receiving slot (12) has a narrow end (121) at one end and a wide end (122) at the other end, and corresponds to The wide end (122) of the groove (12) is provided with a magnetic member (13), and a transmission member (2) is disposed in each of the accommodating grooves (12), and the transmission member (2) is subjected to a normal state. The magnetic attraction of the magnetic member (13) is such that the transmission member (2) is located at the wide end (122) of the accommodating groove (12), and the active member (1) is coupled with a passive member ( 3).

In this way, the creation is used in operation, which causes the power source to drive the driving member (1) to rotate. During the rotation of the driving member (1), due to the centrifugal force, the active member is located ( 1) the transmission member (2) at the wide end (122) of the accommodating groove (12) is moved to the narrow end (121) of the accommodating groove (12) to allow the transmission member ( 2) Positioning the passive member (3) against the top support [please refer to the schematic diagram of the cross-sectional structure of the use state of the third drawing], and let the active member (1) utilize the transmission during the rotation process. The component (2) drives the passive component (3) to rotate; when the passive component (3) is driven to rotate beyond the rotational speed of the active component (1), the active component (1) stops rotating. The transmission member (2) is attracted by the magnetic attraction of the magnetic member (13), and the transmission member (2) is moved back to the wide end (122) of the receiving groove (12), and the active member is at this time (1) with the transmission (2) that is not (3) brought into contact with the driven member, so that the driven member (3) during the rotation i.e. not noise.
