Description

Technical Field

[0001] The invention relates to the technical field of automobile synchronizers, in particular to a one-way locking surface automobile synchronizer. Background Art

[0002] In current life, the old transmission shifts gears by two-foot clutching. When shifting up, the gear stays in the neutral position for a moment, but the clutch needs to be lifted up so that the clutch plate and the flywheel are synchronized. The speed must be consistent to smoothly engage the gear. If the gear shift is slow, the speed drops to idle speed and it cannot be engaged. To downshift, you need to step on the accelerator in the neutral position and keep the clutch lifted at the same time to reduce the speed difference of the gears. However, this operation is relatively complicated and difficult to master accurately. Therefore, designers have created synchronizers, through which the gears to be meshed can reach the same speed and mesh smoothly. Synchronizers are of normal pressure type, inertia type, self-amplification type and other forms. At present, the inertia type synchronizer is widely used. It is mainly composed of a coupling sleeve, a synchronization lock ring, etc. Its characteristic is that it relies on friction to achieve synchronization. The synchronizer is a key component of a mechanical gear transmission automobile transmission. The synchronizer is responsible for shifting gears and transmitting torque. It is a key and vulnerable part in the transmission.

[0003] According to a disclosed automobile synchronizer that is easy to quickly repair (publication number: CN219975176U), the detachable gear piece in the above application is connected to the limit slot through a clamping block to form a preliminary installation, and then cooperates with the locking assembly composed of a locking ring, a second locking hole and a small screw to firmly form a whole with the gear hub body. Since the detachable gear piece is subject to large friction, there is no need to replace the entire automobile synchronizer when it is worn out. Only the detachable gear piece needs to be replaced. The replacement cost is low and it is easy to quickly repair.

[0004] However, when replacing the gear pieces in the above device, special tools are required to install and disassemble multiple groups of small bolts, and the small screws are easy to lose during installation, and it is inconvenient for the staff to align the small screws with the threaded holes, and it is very easy for the threads to slip during installation, which affects the efficiency of installation, reduces work efficiency, and increases the labor of the staff. In view of this, we propose a one-way locking surface automobile synchronizer. Summary of the invention

[0005] The purpose of the present invention is to provide a one-way locking surface automobile synchronizer to solve the problem that small screws in the above-mentioned background technology are easily lost during installation, and it is inconvenient for workers to align the small screws with the threaded holes, and then it is very easy to slip the threads during installation, which affects the installation efficiency and reduces the work efficiency.

The side of the spring away from the rotating ring is fixed on the inner wall of the slot hole. A connecting block is fixed on the outer wall of the spring. One side of the connecting block away from the rotating ring is hinged with a hinge rod. One end of the hinge rod away from the connecting block is hinged with a limiting block. The limiting block penetrates the mounting hole and is slidably connected at the penetration part. A limiting hole is provided on the side wall of the mounting block, and the size of the limiting hole matches the size of the limiting block. By rotating the rotating ring forward, the spring can be contracted, so that the rotating ring drives the connecting block to rotate forward. Through the cooperation of the hinge, the hinge rod can pull the limiting block out of the mounting hole, and then the mounting block can be installed into the mounting hole to align the limiting hole with the limiting block. By loosening the rotating ring, since the spring is in a contracted state, the rotating ring can drive the connecting block to reset. Through the cooperation of the hinge rod, the limiting block can extend into the limiting hole, and the gear ring can be installed on the hub body, which is convenient for the staff to operate, improves the work efficiency, and reduces the labor force of the staff.

[0009] Optionally, the sealing mechanism includes a push block. The push block is slidably mounted on the inner wall of the limiting hole. The top of the push block is fixed with an L-shaped connecting rod, and the L-shaped connecting rod penetrates the top of the mounting block. A connecting rod penetrates the top of the gear ring and is slidably connected at the penetration part. The bottom of the connecting rod is fixed with a sealing block. The outer wall of the sealing block is in contact with the inner wall of the oil storage groove. One end of the L-shaped connecting rod away from the push block is hinged with a movable rod. One end of the movable rod away from the L-shaped connecting rod is hinged on the top of the connecting rod. By providing the sealing block, the effect of blocking and sealing the oil outlet hole can be achieved to prevent lubricating oil from overflowing and causing waste when the gear block is disassembled from the hub body and not in use.

[0010] Optionally, a disc is fixed on the outer wall of the connecting rod. A connecting spring is fixed on the bottom of the disc. The bottom of the connecting spring is fixed on the top of the gear ring.

[0011] Optionally, the oil outlet mechanism includes a slider which is slidably installed on the inner wall of the oil outlet hole. An arc-shaped block is fixed to the side wall of the slider. There are multiple groups of arc-shaped blocks which are arranged in a circumferential array on the toothed ring.

[0012] Optionally, a fixed rod is fixed to the side wall of the slider. The fixed rod penetrates the outer wall of the toothed ring and is slidably connected to the penetration part of the toothed ring. A connecting spring is fixed to the side wall of the slider. The side of the connecting spring away from the slider is fixed to the inner wall of the oil outlet hole. By setting the connecting spring, the effect of resetting the slider can be achieved.

[0013] Optionally, an oil filling port is fixed to the top of the toothed ring. By setting the oil filling port, lubricating oil can be added to the oil storage tank.

[0014] Optionally, there are six groups of limit blocks and limit holes, and the six groups of limit blocks and limit holes are arranged in a circumferential array centered on the center point of the toothed hub body. By setting the six groups of limit blocks and limit holes, the stability of installing the toothed ring on the toothed hub body can be better.

[0015] Compared with the prior art, the present invention provides a one-way locking surface automotive synchronizer, which has the following beneficial effects:

[0016] 1. In order to facilitate the installation of the toothed ring and the toothed hub body, by rotating the rotating ring forward, the winding spring can be contracted, so that the rotating ring drives the connecting block to rotate forward. Through the cooperation of the hinge rod, the hinge rod can pull the limit block out of the installation hole, and then the installation block can be installed into the installation hole to align the limit hole with the limit block. By loosening the rotating ring, because the winding spring is in a contracted state, the rotating ring can drive the connecting block to reset. Through the cooperation of the hinge rod, the limit block can be extended into the limit hole, and the toothed ring can be installed on the toothed hub body, which is convenient for the staff to operate, improves the work efficiency, and reduces the labor force of the staff.

[0017] 2. By setting the oil outlet mechanism, when the tooth block meshes with the corresponding gear and rotates, the tooth block will squeeze the arc-shaped block, so that the arc-shaped block drives the slider to move into the oil storage tank, and the arc-shaped rod extends into the oil storage tank. Then, the lubricating oil in the oil storage tank can flow out to lubricate the tooth block, which can reduce the wear of the tooth block and improve the service life of the device.

[0018] 3. By setting the sealing mechanism, when the toothed ring is disassembled from the toothed hub body, the push block will not be under extrusion pressure. Because the reset spring is in a stretched state, the disc can move downward, which can drive the connecting rod to move downward and the sealing block to move downward to block and seal the oil outlet hole, so that the sealing effect is better, preventing the lubricating oil from overflowing from the oil outlet hole when the toothed ring and the tooth block are removed from the toothed hub body and not in use.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Such as Figures 1-7As shown in the figure, the present invention provides a technical solution: a one-way locking surface automotive synchronizer, which includes a hub body 1, an internal gear ring 13, a gear ring 2 and gear blocks 3; an internal gear ring 13 is fixed to the inner wall of the hub body 1, a gear ring 2 is arranged on the outer wall of the hub body 1, gear blocks 3 are fixed to the outer wall of the gear ring 2, an installation block 5 is fixed to the inner side of the gear ring 2, installation holes 4 are formed in the outer wall of the hub body 1, there are six groups of the installation blocks 5 and the installation holes 4, and the six groups of the installation blocks 5 and the installation holes 4 are arranged in a circumferential array with the center point of the hub body 1 as the center, and the size of the installation block 5 matches the size of the installation hole 4. A slot hole 7 is formed in the hub body 1, and an installation mechanism 6 for facilitating the replacement of the gear blocks 3 is arranged in the slot hole 7.

[0029] Specifically, the installation mechanism 6 includes a rotating ring 601, a hairspring 602, a connecting block 603, a hinged rod 605, a limiting block 604 and a limiting hole 606; the rotating ring 601 penetrates the bottom of the gear hub body 1, and the rotating ring 601 can rotate at the penetration of the bottom of the gear hub body 1. A hairspring 602 is fixed to the inner wall of the rotating ring 601, and one side of the hairspring 602 away from the rotating ring 601 is fixed to the inner wall of the slot 7. By setting the hairspring 602, the rotating ring 601 can be rotated and reset. A connecting block 603 is fixed to the outer wall of the rotating ring 601. A limiting block 604 is slidably installed on the inner wall of the slot 7. A hinged rod 605 is hinged to the connecting block 603. One end of the hinged rod 605 away from the connecting block 603 is hinged to the limiting block 604. Six groups of the connecting block 603, the hinged rod 605 and the limiting block 604 are provided, and the six groups of the connecting block 603, the hinged rod 605 and the limiting block 604 are arranged in a circular array with the center point of the rotating ring 601 as the center. A limiting hole 606 is opened on the side of the mounting block 5 away from the gear ring 2. The size of the limiting hole 606 matches the size of the limiting block 604. When the gear ring 2 and the gear hub body 1 need to be installed, the rotating ring 601 can be rotated forward to contract the hairspring 602. The rotating ring 601 can drive the connecting block 603 to rotate, so that the connecting block 603 pulls the hinged rod 605. The limiting block 604 penetrates the mounting hole 4, so that the hinged rod 605 can pull the limiting block 604 out of the mounting hole 4. The mounting block 5 is placed into the mounting hole 4 to align the limiting block 604 with the limiting hole 606. By loosening the rotating ring 601, since the hairspring 602 is in a contracted state, the hairspring 602 can drive the rotating ring 601 to rotate in reverse, so that the connecting block 603 rotates in reverse. The connecting block 603 can push the limiting block 604, and the limiting block 604 can be pushed into the limiting hole 606, thereby fixing the gear ring 2, facilitating the installation of the gear ring 2 and the gear block 3, improving the work efficiency, and reducing the installation intensity of the staff. When the gear ring 2 and the gear block 3 need to be disassembled, the rotating ring 601 is rotated forward. Through the connecting block 603 and the hinged rod 605, the limiting block 604 can be moved out of the limiting hole 606, thereby quickly releasing the limit on the gear ring 2 and the gear block 3, and removing the gear ring 2 from the gear hub body 1, which is convenient for disassembly. An oil storage groove 9 is opened on the gear ring 2. By setting the oil storage groove 9, lubricating oil can be stored. A plurality of oil outlet holes 11 are opened on the outer wall of the gear ring 2. The plurality of oil outlet holes 11 are arranged in a circular array with the center point of the gear ring 2 as the center, and the oil outlet holes 11 are arranged between the gear blocks 3. Through the oil outlet holes 11, the lubricating oil in the oil storage groove 9 can flow out from the oil outlet holes 11 and flow onto the gear blocks 3, lubricating the gear blocks 3, reducing the wear of the gear blocks 3, and improving the service life. A filling port 10 is fixed to the top of the gear ring 2. By unscrewing the sealing cover on the filling port 10, lubricating oil can be added to the oil storage groove 9. A sealing mechanism 8 for sealing the oil outlet holes 11 is provided on the gear ring 2.

[0030] Specifically, the sealing mechanism 8 includes a push block 801, an L-shaped connecting rod 802, a connecting rod 803, a movable rod 804, a disc 805, a return spring 806, and a sealing block 807. The push block 801 is slidably installed on the inner wall of the limit hole 606. The top of the push block 801 is fixed with an L-shaped connecting rod 802, and the L-shaped connecting rod 802 passes through the mounting block 5, and the passing position can move back and forth. The inner wall of the oil storage tank 9 is fitted with a sealing block 807. The sealing block 807 is made of rubber. By setting the sealing block 807, the oil outlet hole 11 can be effectively sealed. The top of the sealing block 807 is fixed with a connecting rod 803. The connecting rod 803 passes through the top of the toothed ring 2, and the passing position is slidably connected. One end of the L-shaped connecting rod 802 away from the push block 801 is hinged with a movable rod 804. One end of the movable rod 804 away from the L-shaped connecting rod 802 is hinged on the top of the connecting rod 803. When the limit block 604 is inserted into the limit hole 606, the limit block 604 will squeeze the push block 801, making the L-shaped connecting rod 802 approach the oil storage tank 9, making the L-shaped connecting rod 802 squeeze the movable rod 804, making the movable rod 804 squeeze the connecting rod 803 to move upward. A disc 805 is fixed on the outer wall of the connecting rod 803. A return spring 806 is fixed at the bottom of the disc 805. The bottom of the return spring 806 is fixed on the top of the toothed ring 2. By setting the return spring 806, the effect of resetting the connecting rod 803 and the sealing block 807 can be achieved, and the elastic coefficient of the spring 602 is larger than that of the return spring 806. Furthermore, the connecting rod 803 will drive the disc 805 to move upward, stretching the return spring 806. The bottom of the connecting rod 803 is fixed with a sealing block 807. The outer wall of the sealing block 807 is fitted with the inner wall of the oil storage tank 9. Through the setting of the sealing block 807, the connection between the oil outlet hole 11 and the oil storage tank 9 can be sealed. When the connecting rod 803 moves upward, it can drive the sealing block 807 to move upward, so that the sealing block 807 does not seal the oil outlet hole 11, and subsequent lubrication operations can be carried out. An oil outlet mechanism 12 is provided on the toothed ring 2.

[0031] Specifically, the oil outlet mechanism 12 includes a slider 1201, an arc-shaped block 1202, a fixed rod 1203, and a connecting spring 1204; the slider 1201 is slidably installed on the inner wall of the oil outlet hole 11, an arc-shaped block 1202 is fixed to the side wall of the slider 1201, a fixed rod 1203 is fixed to the side wall of the slider 1201, the fixed rod 1203 penetrates the side wall of the tooth ring 2 and is slidably connected at the penetration point. By setting the fixed rod 1203, it can play a role in guiding the arc-shaped block 1202 and the slider 1201. A connecting spring 1204 is fixed to the side wall of the slider 1201, and the side of the connecting spring 1204 away from the slider 1201 is fixed inside the oil outlet hole 11. By setting the connecting spring 1204, it can play a role in resetting the slider 1201. When the tooth block 3 rotates, when the tooth ring 2 is installed on the tooth hub body 1, the sealing block 807 will move upward and not block the oil outlet hole 11. When the tooth block 3 meshes and rotates with the corresponding gear, the teeth of the gear will squeeze the tooth block 3 and the arc-shaped block 1202 in the tooth block 3, and then the arc-shaped block 1202 will drive the slider 1201 to extend into the oil storage tank 9, and then the sealing block 807 will not block the oil outlet hole 11, and then the lubricating oil can flow out from the oil storage tank 9 and flow into the tooth grooves of the tooth block 3, which can lubricate the connection part of the tooth block 3 and prevent severe wear from seriously affecting the service life. When the tooth block 3 rotates to the point where the arc-shaped block 1202 in the tooth groove is not squeezed, because the connecting spring 1204 is in a stretched state, the slider 1201 can be reset. Then, when the tooth ring 2 drives the tooth block 3 to rotate, the lubricating oil can flow out for lubrication operation. When the tooth ring 2 is removed from the tooth hub body 1, because the push block 801 is not under extrusion force and the return spring 806 is in a stretched state, the disc 805 can drive the connecting rod 803 to move downward, and the sealing block 807 will move downward, so that the sealing block 807 can perform secondary sealing on the oil outlet hole 11 to prevent the lubricating oil from overflowing from the oil outlet hole 11 when the tooth ring 2 and the tooth block 3 are removed from the tooth hub body 1 and not in use.

[0032] As an application of this embodiment:

[0033] When it is necessary to install the tooth ring 2 on the tooth hub body 1, rotate the rotating ring 601 in the forward direction to make the hairspring 602 contract. By rotating the rotating ring 601, the connecting block 603 can be driven to rotate, so that the connecting block 603 pulls the hinge rod 605, and the hinge rod 605 can pull the limit block 604 out of the installation hole 4. Insert the installation block 5 inside the tooth ring 2 into the installation hole 4 on the outer wall of the tooth hub body 1, align the limit block 604 and the limit hole 606, and by releasing the rotating ring 601, because the hairspring 602 is in a contracted state, the hairspring 602 can drive the rotating ring 601 to rotate in the reverse direction, the connecting block 603 will rotate in the reverse direction, and the connecting block 603 can push the limit block 604, and the limit block 604 can be pushed into the limit hole 606, and then the tooth ring 2 can be fixed.

[0034] When the toothed ring 2 is installed on the toothed hub body 1, the limiting block 604 will extend into the limiting hole 606 to squeeze the push block 801, causing the L-shaped connecting rod 802 to approach the oil storage tank 9, causing the L-shaped connecting rod 802 to squeeze the movable rod 804, causing the movable rod 804 to rotate at the hinge, causing the movable rod 804 to squeeze the connecting rod 803 to move upward, causing the disc 805 to drive the return spring 806 to stretch. When the connecting rod 803 moves upward, it can drive the sealing block 807 to move upward, so that the sealing block 807 does not seal the oil outlet hole 11, and subsequent lubrication operations can be carried out. When the sealing block 807 does not seal the oil outlet hole 11, when the device is in use, the tooth block 3 will mesh and rotate with the corresponding gear. When the tooth of the gear rotates into contact with the arc block 1202, it will squeeze the arc block 1202, causing the arc block 1202 to drive the slider 1201 to extend into the oil storage tank 9, and further causing the sealing block 807 not to block the oil outlet hole 11. Further, the lubricating oil can flow out of the oil storage tank 9 and flow into the tooth groove of the tooth block 3, and the connection part of the tooth block 3 can be lubricated. When the tooth block 3 rotates so that the arc block 1202 in the tooth groove is not squeezed, it can be reset by the connecting spring 1204.

[0035] When maintenance of the tooth block 3 is required, the rotating ring 601 can be rotated forward to contract the hairspring 602. The rotating ring 601 can drive the connecting block 603 to rotate, causing the connecting block 603 to pull the articulated rod 605, causing the articulated rod 605 to pull the limiting block 604 out of the limiting hole 606, and thus the limit on the toothed ring 2 can be released, and the toothed ring 2 can be removed from the toothed hub body 1. When the toothed ring 2 is removed from the toothed hub body 1, since the push block 801 is not under extrusion force and the return spring 806 is in a stretched state, the disc 805 can drive the connecting rod 803 to move downward, causing the sealing block 807 to move downward, so that the sealing block 807 can perform secondary sealing on the oil outlet hole 11, preventing the lubricating oil from overflowing from the oil outlet hole 11 when the toothed ring 2 and the tooth block 3 are removed from the toothed hub body 1 and not in use.

[0036] The above text generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
