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.

The ring 2 is removed from the gear hub body 1 for easy disassembly. An oil storage tank 9 is provided on the gear ring 2, and lubricating oil can be stored by setting the oil storage tank 9. An oil outlet hole 11 is provided on the outer wall of the gear ring 2. There are multiple groups of oil outlet holes 11, and the multiple groups 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. The lubricating oil in the oil storage tank 9 can flow out from the oil outlet holes 11 through the oil outlet holes 11 and flow onto the gear blocks 3, so as to lubricate the gear blocks 3, reduce the wear of the gear blocks 3, and improve the service life. A refueling port 10 is fixed on the top of the gear ring 2. Lubricating oil can be added to the oil storage tank 9 by unscrewing the sealing cover on the refueling port 10. A sealing mechanism 8 for sealing the oil outlet hole 11 is provided on the gear ring 2.

[0022] 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 reset spring 806 and a sealing block 807. The push block 801 is slidably mounted on the inner wall of the limiting 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 penetration point can move back and forth. The inner wall of the oil storage tank 9 is attached with a sealing block 807, and the sealing block 807 is made of rubber. By setting the sealing block 807, In order to effectively seal the oil outlet hole 11, a connecting rod 803 is fixed to the top of the sealing block 807, and the connecting rod 803 passes through the top of the gear ring 2, and the penetration is slidably connected. The end of the L-shaped connecting rod 802 away from the push block 801 is hinged with a movable rod 804, and the end of the movable rod 804 away from the L-shaped connecting rod 802 is hinged at the top of the connecting rod 803. When the limit block 604 is extended into the limit hole 606, the limit block 604 squeezes the push block 801, so that the L-shaped connecting rod 802 is close to the oil storage tank 9. , so that the L-shaped connecting rod 802 squeezes the movable rod 804, so that the movable rod 804 squeezes the connecting rod 803 to move upward, the outer wall of the connecting rod 803 is fixed with a disk 805, the bottom of the disk 805 is fixed with a reset spring 806, and the bottom of the reset spring 806 is fixed to the top of the gear ring 2. By setting the reset spring 806, the connecting rod 803 and the sealing block 807 can be reset, and the elastic coefficient of the clockwork 602 is greater than the elastic coefficient of the reset spring 806, which will make the connecting rod 803 The disc 805 is driven upward to move upward, so that the reset spring 806 is stretched. A sealing block 807 is fixed to the bottom of the connecting rod 803. The outer wall of the sealing block 807 fits with the inner wall of the oil storage tank 9. The setting of the sealing block 807 can seal the connection between the oil outlet 11 and the oil storage tank 9. 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 11, and subsequent lubrication operations can be carried out. An oil outlet mechanism 12 is provided on the gear ring 2.

[0023] Specifically, the oil outlet mechanism 12 includes a slider 1201, an arc block 1202, a fixing rod 1203 and a connecting spring 1204; the slider 1201 is slidably mounted on the inner wall of the oil outlet hole 11, the side wall of the slider 1201 is fixed with an arc block 1202, the side wall of the slider 1201 is fixed with a fixing rod 1203, the fixing rod 1203 penetrates the side wall of the gear ring 2, and is slidably connected at the penetration point, and the fixing rod 1203 can guide the arc block 1202 and the slider 1201, and the sliding The side wall of the block 1201 is fixed with a connecting spring 1204, and the side of the connecting spring 1204 away from the slider 1201 is fixed to the inner side of the oil outlet hole 11. By setting the connecting spring 1204, the slider 1201 can be reset. When the tooth block 3 rotates, when the gear ring 2 is installed on the gear hub body 1, the sealing block 807 will move upward and not block the oil outlet hole 11. When the tooth block 3 and the corresponding gear mesh and rotate, the teeth of the gear will squeeze the tooth block 3 and the arc in the tooth block 3. The arc block 1202 drives the slider 1201 into the oil storage tank 9, so that the sealing block 807 does not block the oil outlet 11, so that the lubricating oil can flow out of the oil storage tank 9 and flow into the tooth groove of the tooth block 3, so as to lubricate the connection of the tooth block 3 and prevent the wear from seriously affecting the service life. When the tooth block 3 rotates to the point where it is not squeezed by the arc block 1202 in the tooth groove, the slider 1201 can be reset because the connecting spring 1204 is in a stretched state. When the gear ring 2 drives the gear block 3 to rotate, the lubricating oil can flow out to perform lubrication operations. When the gear ring 2 is removed from the gear hub body 1, since the push block 801 is not subjected to extrusion force and the return spring 806 is in a stretched state, the disc 805 can drive the connecting rod 803 to move downward, so that the sealing block 807 can move downward, and the sealing block 807 can perform secondary sealing on the oil outlet hole 11 to prevent the gear ring 2 and the gear block 3 from being removed from the gear hub body 1 and causing the lubricating oil to overflow from the oil outlet hole 11 when not in use.

[0024] As an application of this embodiment: When the gear ring 2 needs to be installed on the gear hub body 1, the rotating ring 601 is rotated forward to shrink the mainspring 602, and the connecting block 603 can be driven to rotate by the rotating ring 601, so that the connecting block 603 pulls the hinge rod 605, so that the hinge rod 605 can pull the limit block 604 out of the mounting hole 4, and the mounting block 5 on the inner side of the gear ring 2 is inserted into the mounting hole 4 on the outer wall of the gear hub body 1, so that the limit block 604 and the limit hole 606 are aligned, and by loosening the rotating ring 601, since the mainspring 602 is in a contracted state, the mainspring 602 can drive the rotating ring 601 to reverse, so that the connecting block 603 can reverse, and the connecting block 603 can push the limit block 604, and the limit block 604 can be pushed into the limit hole 606, so that the gear ring 2 can be fixed.

[0025] When the gear ring 2 is installed on the gear hub body 1, the limit block 604 will extend into the limit hole 606 to squeeze the push block 801, so that the L-shaped connecting rod 802 is close to the oil storage tank 9, and the L-shaped connecting rod 802 squeezes the movable rod 804, so that the movable rod 804 rotates at the hinge, so that the movable rod 804 squeezes the connecting rod 803 to move upward, so that the disc 805 drives the reset 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 oil hole 11 is sealed, when the device is in use, the tooth block 3 will mesh and rotate with the corresponding gear. When the teeth of the gear rotate to contact the arc block 1202, the arc block 1202 will be squeezed, and the arc block 1202 will drive the slider 1201 to extend into the oil storage tank 9, so that the sealing block 807 will not block the oil outlet hole 11, and the lubricating oil can flow out of the oil storage tank 9 and flow into the tooth groove of the tooth block 3, so as to lubricate the connection of the tooth block 3. When the tooth block 3 rotates to the point where it is no longer squeezed by the arc block 1202 in the tooth groove, it can be reset by connecting the spring 1204.

[0026] When the gear block 3 needs to be maintained, the rotating ring 601 can be rotated forward to shrink the spring 602, and the connecting block 603 can be driven to rotate by the rotating ring 601, so that the connecting block 603 pulls the hinge rod 605, so that the hinge rod 605 pulls the limit block 604 to move out of the limit hole 606, and then the limit on the gear ring 2 can be released, and the gear ring 2 can be moved out of the gear hub body 1. When the gear ring 2 is removed from the gear hub body 1, because the push block 801 is not subjected to the extrusion force and the reset spring 806 is in a stretched state, the disc 805 can drive the connecting rod 803 to move downward, so that the sealing block 807 can move downward, so that the sealing block 807 can perform secondary sealing on the oil outlet hole 11 to prevent the gear ring 2 and the gear block 3 from being removed from the gear hub body 1. When not in use, the lubricating oil overflows from the oil outlet hole 11.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
