Improvement of wheel speed sensor drive structure

The present invention relates to an improvement of a driving structure of a wheel speed sensor, in particular to an outer edge of one end of a driven gear of a driven unit assembled on a shaft tube of a horse gear housing, and a plurality of ears having a hemispherical end portion are formed. And at the inner edge of the end hole of the locomotive front wheel hub shaft tube, a plurality of driving blocks which can be divided by the number of the ear pieces provided by the driven gear, and the end edge of the hub shaft tube nozzle and the end portions of the driving blocks are provided It is a circular arc end, and since the driven gear and the plurality of ears thereon are made of reinforced plastic, the ears are slightly elastic, and when the horse gear housing is assembled to the hub shaft end, The driving block for the inner edge of the end hole of the hub shaft can be arbitrarily aligned with the groove corresponding to the plurality of ears embedded in the outer edge of one end of the driven gear, so that the assembler can smoothly follow the driven gear or ABS without visual alignment. The magnetic zone components are mounted at the concentric positioning of the hub axle.

According to the conventional wheel speed sensor driving structure, as shown in the fourth figure, it is mainly at the end of the locomotive front wheel hub (4) shaft tube (41), and is provided with a set of driving ears (42), at which end another The horse-gear gear housing (5), which must be located in the front fork frame of the locomotive not rotating with the hub (4), is provided with a driven unit (52) at the central shaft tube (51) of the horse-type gear housing (5). The front portion of the driven unit (52) has a tooth pattern (521), and the other portion has a driving ring member (522) having an outer edge having a set of lug pieces (523), and the driven unit (52) is a The C-shaped buckle (53) is positioned on the shaft tube (51) of the horse gear housing (5), in the aforementioned horse gear housing (5) On one side, there is a wheel speed sensing unit (54), and the wheel speed sensing unit (54) includes a speed output gear (541) driven by a tooth (521) in front of the driven unit (52), and a speed output a magnetic zone component (542) for synchronously rotating the gear (541) and an inductive component (55) connected to the signal line (551) are provided when the locomotive travels to rotate the shaft tube (41) of the front wheel drive hub (4). The set of driving ears (42) at the end of the shaft tube (41) drives the lug piece (523) around the periphery of the driving ring member (522) to rotate the driving ring member (522) while causing the front portion to have a tooth pattern ( 521) integrally rotating, and then driving the rotation output gear (541) and the magnetic zone component (542) provided on the horse gear housing (5) to rotate, and the sensing component disposed on one side of the magnetic zone component (542) (55) The magnetic zone change on the inductive magnetic zone component (542), and the data is transmitted from the signal line (551) to the electronic horse watch for display speed and mileage purposes.

In addition, another structure for sensing the ABS signal or the electronic horse meter signal, as shown in the fifth figure, mainly has a tooth pattern (521) to a magnetic zone component in the previous section of the structure shown in the fourth figure. Instead, the magnetic zone element (57) is assembled on the sleeve portion (524) formed by the drive ring member (522) and directly to the wheel speed sensor housing (5') and the magnetic zone component (57). Correspondingly, an inductive component (55) connected to the signal line (551) is set, and the magnetic component change on the magnetic zone component (57) is induced by the sensing component (55), and the data is transmitted from the signal line (551) to the signal line (551). Electronic horse watch, and up to ABS signal sensing or electronic horse meter signal sensing to display speed and mileage.

However, the conventional structure has the following disadvantages:

1. Interference will be generated to cause abnormal operation or unable to drive: the drive ring (522) cannot be seen when the driven unit (52) is installed in the horse gear housing (5) and assembled on the assembly line or in the maintenance factory. Whether the peripheral lug (523) is indeed aligned with the drive ear groove (421) between the set of drive ears (42) on the shaft tube (41) The lug piece (523) on the periphery of the moving ring member (522) is misaligned and completely inserted into the driving ear groove (421) between the set of driving ears (42) on the shaft tube (41) to interfere with each other without being found At this time, when the axle fixing screw (56) is locked again, the lug piece (523) of the periphery of the driving ring member (522) is crushed by the group of driving ears (42) on the shaft tube (41) to cause damage or breakage. In turn, the tire can not be rotated smoothly, and the driven unit (52) can not accurately drive the wheel speed sensing unit (54) or can not be used.

2, used in ABS signal or electronic horse meter signal can not be read to produce ABS brake car malfunction or horse table data display abnormal: This custom design, because the assembly needs to reserve clearance so that the assembly can not be visually aligned during installation Whether the lug piece (523) on the periphery of the drive ring member (522) has been properly aligned with the drive ear groove (421) between the set of drive ears (42) on the shaft tube (41) by the feel of the assembler The two are aligned, so a large gap drive ear slot (421) needs to be reserved for ease of installation.

This design does not cause problems in the use of early mechanical horse watches, but today's vehicles have used a large number of electronic horse watches, or have used the ABS brake anti-lock system, and the conventional design is used for the wheel speed sensing of today's vehicles. When the vehicle is started or braked, the driving ring member (522) and the magnetic domain member (57) (ABS coded magnetic ring) may be on the shaft tube (41) due to inertia. A large gap between the driving ears (42) drives the ear slot (421) to freely rotate or bounce in the gap range to cause signal increase or decrease or delay, resulting in abnormal display of the watch and ABS brake, and using the drive ring (522) When the center hole is the center of rotation, the error will become more obvious after the long-term wear center hole and the shaft tube (51') in the wheel speed sensor housing (5') become larger, and the ABS brake signal problem will also occur.

In view of the practical difficulties of the above-mentioned conventional wheel speed sensor driving structure and the lack of improvement, the creator hopes to provide a breakthrough design to enhance the practical effect, which is a concentrated research and design system.

And at the inner edge of the end hole of the axle tube of the front wheel hub of the locomotive, a plurality of driving blocks which are divisible by the number of the ears provided by the sleeve assembly, and the end edges of the hub shaft tube and the end portions of the driving blocks are It is a circular arc end, and since the driven unit is made of reinforced plastic, the ear pieces are slightly elastic, and the wheel hub is assembled when the horse wheel gear housing is assembled to the hub shaft end of the wheel axle fixing screw. The arc end of the end of the driving block at the inner edge of the end hole of the shaft tube can be arbitrarily and quickly aligned into the groove corresponding to the ear piece provided in the insert sleeve assembly. When the two are assembled with each other, the ear piece is slightly different from the sleeve assembly. Flexible, even if the two interfere with each other, with the drive blocks in contact The arc end of the end and the end of any ear piece and the arc end of the hub tube of the hub are also formed with a circular end, so that the sleeve can smoothly slide and drive the block in the hub tube. Alignment so that the assembler can smoothly install the driven gear or ABS magnetic zone component in the concentric positioning of the hub axle tube without visual alignment.

The main purpose of the present invention is to make the ear piece smoothly slide and the wheel by the arc end of the driving block contact end and the end of any ear piece and the arc end formed at the opening of the hub shaft tube. The driving blocks in the shaft tube are aligned so that the assembler can install the driven gear or the ABS magnetic zone component in the concentric positioning of the hub axle tube without visual alignment, so that the wheel speed and the ABS coded magnetic piece are concentric with the shaft tube. Rotation, in order to achieve the wheel speed signal is indeed easy to disassemble.
