Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 3, the present embodiment provides an external wheel speed monitoring device, which includes a shaft cover 1, a bearing 2 is disposed at the bottom of the shaft cover 1, a rotatable frame body 3 is disposed on the bearing 2, a wheel speed monitoring device 8 and a fixing rod 4 extending towards the axle direction are disposed on the frame body 3, and a gear ring matched with the wheel speed monitoring device 8 is disposed on the shaft cover 1. In this embodiment, the frame body 3 is plate-shaped, the frame body 3 is provided with a mounting hole, and the bearing 2 is inserted into and fixed to the mounting hole, so that the frame body 3 can rotate around the bearing 2; a counter bore 6 is arranged on the mounting hole, and an annular groove is formed in the part of the bearing 2 extending into the counter bore 6; the bearing 2 further comprises a gasket, the gasket is clamped in the annular groove, and the outer diameter of the gasket is larger than the inner diameter of the mounting hole.

Above-mentioned external wheel speed monitoring devices sets up counter bore 6 in the mounting hole department of support body 3, sets up the ring channel on bearing 2, and the gasket sets up on the ring channel, and simultaneously, the gasket wholly is located counter bore 6. Through setting up the mutual motion of the gasket restriction support body 3 and bearing 2 at the ring channel, avoid support body 3 to break away from bearing 2, improve the joint strength of bearing 2 and support body 3, avoid bearing 2 and support body 3 to appear becoming flexible or break away from because of becoming flexible.

Specifically, in the present embodiment, the gasket is installed when the bearing 2 is inserted into the installation hole, and for convenience of installing the gasket, the gasket is an opening gasket 7.

More specifically, for better holding the open gasket 7 of the tweezers, two ends of the opening of the open gasket 7 are respectively provided with an outward protruding sheet. Meanwhile, when needed, the two ends of the opening gasket 7 can be connected through an iron sheet or an iron wire, and at the moment, the protruding sheet is provided with an opening.

Specifically, in this embodiment, the gasket is partially located on the step formed by the counterbore 6, and is partially clamped in the annular groove, and for better operation, the annular groove is configured as follows: the lower end of the annular groove is flush with the bottom of the counter bore 6.

Specifically, in this embodiment, the frame body 3 is rectangular, and the symmetry line of the frame body 3 coincides with the symmetry line of the axle head cover 1, so that the frame body 3 is concentric with the axle head cover 1 when rotating.

More specifically, in the present embodiment, the frame body 3 is provided with a fixing rod 4 and a wheel speed monitoring device 8 near both ends in the length direction. With dead lever 4 and the fast monitoring devices of wheel 8 symmetry respectively and set up the both ends on 3 length directions of support body, can improve the symmetry of support body 3, avoid support body 3 lateral deviation.

More specifically, in this embodiment, the fixing rod 4 extends toward the spindle nose nut of the axle and is engaged with the tongue-and-groove of the spindle nose nut. The dead lever 4 extends to the epaxial spindle nose nut direction of axletree to the joint is on spindle nose nut, compares 4 butt axletree portions of dead lever with among the prior art, and the joint can improve and connect the rigidity, avoids appearing mutual displacement between dead lever 4 and the axletree, and then improves the accuracy of the fast monitoring of wheel.
