The ring gear fixing device 10 of the present utility model is provided as a general-purpose ring gear fixing device, and can be adapted to fix ring gears 2 of different sizes by adjustment, so that performance tests of wheel speed sensors in different projects can be satisfied.

The gear ring 2 is fixed on the gear ring fixing device 10, and the motor is fixedly connected with the fixing body 11 of the gear ring fixing device 10 and drives the fixing body 11 to rotate. The wheel speed sensor is arranged opposite to the gear ring 2, and the gap between the wheel speed sensor and the gear ring 2 is adjusted according to different gear rings 2. The data acquisition device is electrically connected with the wheel speed sensor and acquires signals of the wheel speed sensor.

The ring gear fixing device 10 includes a fixing body 11, a retainer ring 12 provided to the fixing body 11, and an adjusting mechanism engaged with the retainer ring 12. The adjusting mechanism comprises an adjusting piece 13 movably assembled on the positioning ring 12, and the adjusting piece 13 can be moved relative to the positioning ring 12 in a radial direction in an adjustable manner so as to adjust the outer contour diameter of the adjusting piece 13. In this embodiment, the adjustment member 13 is fixed to the ring gear fixing device 10 by the adjustment member 13 abutting against the ring gear 2.

In one embodiment, the fixing body 11 is a cylindrical shell with an opening at one end, and the positioning ring 12 is located in the fixing body 11, and the positioning ring 12 is disposed concentrically with the circumferential surface of the cylindrical shell. Of course, in other embodiments, the fixing body 11 may be provided in any shape, which is not particularly limited herein.

In the ring gear fixing device 10 of the present utility model, the fixing body 11 and a side surface facing away from the retainer ring 12 are provided with the mounting portion 111, and the mounting portion 111 is configured to be assembled with a motor to drive the ring gear fixing device 10 to rotate by the motor, so that the rotation of a wheel can be simulated to perform performance test of a wheel speed sensor. In one embodiment, the mounting portion 111 is a connection hole provided at a side of the fixing body 11, and the motor may be connected to the fixing body 11 by being fixed to the connection hole through a structural member.

Further, the adjusting mechanism further comprises a driving member 14, wherein the driving member 14 can move adjustably along the axial line direction of the positioning ring 12 so as to drive the adjusting member 13 to move radially of the positioning ring 12. In the present utility model, the driving member 14 is provided in conjunction with the adjusting member 13, and the driving member 14 is controlled to move in the axial line direction of the positioning ring 12 to drive the adjusting member 13 to move in the radial direction of the positioning ring 12, for example: the adjusting piece 13 can be driven to move outwards of the positioning ring 12 by moving the adjusting driving piece 14 towards the positioning ring 12, so that the gear ring 2 with a large size can be adapted; by displacing the adjusting drive 14 away from the setting collar 12, the adjusting element 13 is displaced into the setting collar 12, which can be adapted to the small-sized gear ring 2. Alternatively, by moving the adjustment drive member 14 toward the retainer ring 12, the adjustment member 13 is moved into the retainer ring 12, and can be adapted to the small-sized ring gear 2; by moving the adjusting drive member 14 away from the positioning ring 12, the adjusting member 13 can be driven to move outwards of the positioning ring 12, and the gear ring 2 with a large size can be adapted.

In the embodiment of the utility model, the driving member 14 includes a shaft 141 and a cone 142 disposed on the shaft 141, and the cone 142 abuts against the adjusting member 13. The cone 142 has a reduced size in the direction of the driving member 14 toward the stationary body 11, so that the adjusting member 13 can be driven to move outward of the retainer ring 12 during the movement of the driving member 14 toward the retainer ring 12, thereby adapting to the large-sized ring gear 2.

The driving member 14 further includes a connection portion (not shown) disposed at an end of the driving member 14 near the fixing body 11, and the fixing body 11 is provided with an engaging portion 112.

The driving member 14 is screw-coupled with the fixing body 11 by rotating the shaft body 141, so that the cone 142 is moved to push the adjusting member 13 to move in the radial direction of the positioning ring 12. Wherein the length of the threaded shaft is less than the height of the cone 142.

Correspondingly, the adjusting member 13 is a plurality of cylinders, round holes matched with the cylinders are formed in the periphery of the positioning ring 12, and the cylinders are uniformly distributed on the positioning ring 12. By the arrangement of the plurality of cylinders, the fixing strength of the adjuster 13 to the ring gear 2 can be enhanced. The end of the adjusting member 13 contacting the cone 142 is configured in an arc shape, so that the cone 142 and the cylinder are matched, friction force between each other is reduced, and direction conversion of thrust force is facilitated. Furthermore, the end of the cylinder that contacts the ring gear 2 may be provided to be flexible, facilitating mutual abutment fixation.

In the present utility model, when performing the performance test of the wheel sensor, the ring gear 2 to be tested is first mounted to the ring gear fixing device 10, specifically, the shaft body 141 of the driving member 14 is rotated to make the cone 142 abut against the cylinder, so that the cylinder gradually extends out of the positioning ring 12 and abuts against the ring gear 2, thus fixing the ring gear 2 to the ring gear fixing device 10, finally, the ring gear fixing device 10 is mounted to the motor, and the wheel speed sensor is mounted at the side of the ring gear 2, thereby performing the performance test of the wheel speed sensor.

According to the gear ring fixing device and the performance testing equipment of the wheel speed sensor, the gear ring fixing device is arranged to be adjustable in diameter, so that the gear ring fixing device can be assembled with various gear rings with different sizes, the universality of the gear ring fixing device is improved, and the testing period of the wheel speed sensor is shortened.
