Problems solved by technology

[0007] Although the above nut locking scheme can achieve a certain degree of locking effect, the nut of the shaft nut cannot realize the fine adjustment of the pre-tightening force, and it is impossible to adjust the depth of the shaft nut screwed into the axle according to the size of the specific bearing and the installation requirements. That is, the clearance of the bearing cannot be adjusted, or the force of pressing the bearing cannot be controlled, that is, the pressure on the bearing cannot be controlled, so that the bearing and the axle cannot be effectively protected, and the locking effect of the axle nut itself is poor

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail;

[0020] Such as figure 1 , 2 , 3, 4, and 5, a new type of shaft nut, including a threaded body 1 that is threaded with the axle, and a locking flange 2 integrally formed with the threaded body 1, between the threaded body 1 and the An inner cavity 3 that can accommodate the axle is formed between the locking flanges 2. The inner cavity 3 is arranged through the axis of the axle head nut, and is on the back 21 of the locking flange 2, around the locking flange 2. A key 4 connected to the hub of the axle is provided in the circumferential direction of the axis of the threaded body 1. In the inner cavity 3 of the threaded body 1, around the axis of the threaded body 1, a plurality of threads along the inner wall 11 of the threaded body 1 are provided in the circumferential direction. Splines 5 arranged in the axial direction of the connecting body...

Abstract

The invention discloses a novel axle head nut which comprises a threaded connector and a locking flange, wherein the threaded connector is in threaded fit with an axle, and the locking flange and the threaded connector are integrally formed. An inner cavity capable of containing the axle is formed between the threaded connector and the locking flange, and a key connected with a hub of the axle is circumferentially arranged around the axis of the locking flange and on the back surface of the locking flange. The novel axle head nut is characterized in that a plurality of splines arranged along the axis direction of the threaded connector are circumferentially arranged on the inner wall of the threaded connector around the axis of the threaded connector in the inner cavity of the threaded connector, a fine-adjustment function for pre-tightening force of the axle head nut is achieved, a bearing is protected, the service life of the bearing is prolonged, so that the service life of the whole axle is prolonged, the strength of an axle body and the axle head nut cannot be affected while the fine-adjustment function is achieved, driving safety is ensured, a spline structure is formed once by forging and extruding, and the strength of the splines is ensured.

Description

technical field [0001] The patent of the present invention relates to the field of automobiles, in particular to a novel axle nut. Background technique [0002] At present, most of the locking and locking methods of domestic axle head nuts are locked by locking plates, which have a large adjustment range and are prone to over-tightening or over-loosening, which will seriously affect the life of the bearing; [0003] CN 202579587 U discloses a shaft head locking device for an axle, which includes a first nut (1) and a second nut (2). One end of the screw hole of the first nut (1) is provided with a radial An open conical lock tongue, one end of the second nut (2) is provided with a conical extrusion part corresponding to the shape of the lock tongue of the first nut (1) along the outer circumference. Using the shaft head locking device for axles of the present invention, the two nuts squeeze each other during installation, so that their threads are slightly deformed, and at ...
