Description

Technical Field

[0001] This utility model relates to the field of synchronizer technology, and in particular to a synchronizer gear hub core. Background Technology

[0002] Synchronizers are an important component in automotive transmissions. They are mainly used to synchronize the gear speeds during gear shifting, reduce the impact between gears, and thus ensure a smooth gear shifting effect. During the assembly of synchronizers, a gear hub core is used to combine the various components of the synchronizer.

[0003] Existing technologies often have the following drawbacks: during the assembly of synchronizers using synchronizer hub cores, it is often necessary to lift the synchronizer hub core and then install other synchronizer components onto it. Afterward, tools are needed to control the contraction of the positioning elastic element, making the synchronizer assembly process quite complex.

[0004] Therefore, this utility model provides a synchronizer hub disc core. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, when assembling a synchronizer using a synchronizer hub disc core, it is often necessary to lift the synchronizer hub disc core and then install other synchronizer components onto the synchronizer hub disc core. After that, tools are needed to control the contraction of the positioning elastic element, which makes the assembly of the synchronizer more complicated. Therefore, a synchronizer hub disc core is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a synchronizer hub disc core, comprising a disc core body, a base mounted on the lower surface of the disc core body, four support plates fixedly connected to the side of the base, all four support plates being tightly fitted to the disc core body, and a second clamping plate fixedly connected to the side of each of the four support plates near the disc core body, the second clamping plate being tightly fitted to the disc core body.

[0007] The above components achieve the following effects: by setting the base and support plate, the disc core body can be lifted; by setting the second clamping plate, the positioning effect can be achieved.

[0008] Preferably, each of the four trays is fixedly connected to a first clamping plate on the side closest to the core body, and a bent rod is fixedly connected to the side of the tray away from the base.

[0009] The effect achieved by the above components is that by setting the first clamp, the base can be positioned.

[0010] Preferably, a positioning plate is fixedly connected to the end of the bent rod away from the second clamping plate, and the positioning plate is in close contact with the disc core body.

[0011] The effect achieved by the above components is that the positioning plate can be connected to the second clamp by setting the bent rod, and the positioning plate can achieve the positioning effect.

[0012] Preferably, an "L"-shaped telescopic plate is fixedly connected to the side of the second clamp away from the base, and the vertical cross-section of the "L"-shaped telescopic plate is "L".

[0013] The effect achieved by the above components is that the "L"-shaped telescopic plate and the base can be connected by setting the second clamp.

[0014] Preferably, a limiting plate is installed on the side of the "L"-shaped telescopic plate near the disk core body, and the cross-section of the limiting plate is "U"-shaped.

[0015] The effect achieved by the above components is as follows: by setting the "L"-shaped telescopic plate, the limiting plate can be installed conveniently; by setting the limiting plate, the positioning elastic element can be positioned when it is installed onto the disc core body, thereby improving the installation efficiency of the positioning elastic element.

[0016] Preferably, a connecting rod is fixedly connected to the side of the limiting plate near the "L"-shaped telescopic plate, and the other end of the connecting rod is fixedly connected to the "L"-shaped telescopic plate.

[0017] The effect achieved by the above components is that by setting the connecting rod, a stable connection between the limiting plate and the "L"-shaped telescopic plate can be ensured.

[0018] Preferably, an arc-shaped block is fixedly connected to the side of the limiting plate away from the connecting rod, and the upper surface of the arc-shaped block is arc-shaped.

[0019] The effect achieved by the above-mentioned components is that by setting the arc-shaped block, it is convenient to control the contraction of the elastic element used for positioning when installing, thereby facilitating its installation.

[0020] In summary:

[0021] In this invention, by setting a base and a support plate, the disk core body can be lifted during the assembly of the synchronizer. By setting a first clamping plate and a second clamping plate, as well as a bent rod and a positioning plate, the disk core body can be positioned when placed on the support plate. By setting an "L"-shaped telescopic plate, a connecting rod and a limiting plate, the positioning elastic element can be positioned during installation. By setting an arc-shaped block, the contraction of the positioning elastic element can be easily controlled, facilitating the assembly of the synchronizer. Attached Figure Description

[0027] Reference Figures 1-3 As shown, this utility model provides a technical solution: a synchronizer hub disc core, including a disc core body 1, a base 2 mounted on the lower surface of the disc core body 1, four support plates 3 fixedly connected to the side of the base 2, all four support plates 3 being tightly fitted to the disc core body 1, and a second clamping plate 5 fixedly connected to the side of each of the four support plates 3 near the disc core body 1, the second clamping plate 5 being tightly fitted to the disc core body 1. By setting the base 2 and support plates 3, the disc core body 1 can be lifted, and by setting the second clamping plates 5, a positioning effect can be achieved.

[0028] The following is a detailed explanation of its overall setup and function.

[0029] Reference Figures 1-4 As shown in this embodiment: Each of the four support plates 3 has a first clamping plate 4 fixedly connected to the side closest to the disk core body 1, and a bent rod 6 fixedly connected to the side of the support plate 3 away from the base 2. The first clamping plates 4 provide a positioning effect for the base 2. A positioning plate 7 is fixedly connected to the end of the bent rod 6 away from the second clamping plate 5, and the positioning plate 7 fits tightly against the disk core body 1. The positioning plate 7 can be connected to the second clamping plate 5 by the bent rod 6, thus providing a positioning effect. An "L"-shaped telescopic plate 8 is fixedly connected to the side of the second clamping plate 5 away from the base 2, and the vertical cross-section of the "L"-shaped telescopic plate 8 is "L". The second clamping plate 5 connects the "L"-shaped telescopic plate 8 to the base 2.

[0030] A limiting plate 10 is installed on the side of the "L"-shaped telescopic plate 8 near the core body 1. The limiting plate 10 has a "U"-shaped cross-section. The "L"-shaped telescopic plate 8 facilitates the installation of the limiting plate 10 and provides a positioning effect when installing the positioning elastic element onto the core body 1, improving the installation efficiency of the positioning elastic element. A connecting rod 9 is fixedly connected to the side of the limiting plate 10 near the "L"-shaped telescopic plate 8, and the other end of the connecting rod 9 is fixedly connected to the "L"-shaped telescopic plate 8. The connecting rod 9 ensures a stable connection between the limiting plate 10 and the "L"-shaped telescopic plate 8. An arc-shaped block 11 is fixedly connected to the side of the limiting plate 10 away from the connecting rod 9. The upper surface of the arc-shaped block 11 is arc-shaped. The arc-shaped block 11 facilitates the control of the contraction of the positioning elastic element during installation, thus simplifying its installation.

[0031] Working principle: During the assembly of the synchronizer, first place the base 2 on the operating table, then move the core body 1 closer to the support plate 3, so that the core body 1 is locked between the first clamping plate 4 and the second clamping plate 5. Rotate the core body 1 so that it fits against the positioning plate 7. Then move the synchronizer engagement sleeve closer to the core body 1, and then move the positioning elastic element closer to the limiting plate 10. Continue to move the positioning elastic element closer to the base 2. At this time, under the push of the arc-shaped block 11, the positioning elastic element retracts, thereby locking between the core body 1 and the engagement sleeve. Then control the "L"-shaped telescopic plate 8 to extend, move the core body 1 away from the base 2, and then move the other synchronizer components closer to the core body. The system can be configured as follows: 1) By setting the bent rod 6, the positioning plate 7 and the support plate 3 can be connected; by setting the connecting rod 9, the limiting plate 10 can be installed; by setting the base 2 and the support plate 3, the disk core body 1 can be lifted during the assembly of the synchronizer; by setting the first clamping plate 4, the second clamping plate 5, the bent rod 6, and the positioning plate 7, the disk core body 1 can be positioned when placed on the support plate 3; by setting the "L"-shaped telescopic plate 8, the connecting rod 9, and the limiting plate 10, the positioning elastic element can be positioned during installation; and by setting the arc-shaped block 11, the retraction of the positioning elastic element can be easily controlled, facilitating the assembly of the synchronizer.
