Anti-loose locking device of gear type axle head

Abstract

The invention discloses an anti-loose locking device of a gear type axle bridge head, and belongs to the technical field of locking of axle bridge heads. The bearing baffle is arranged on an axle and used for preventing a hub bearing from moving outwards, the first-stage anti-loosening assembly is arranged on the axle and located on the outer side of the bearing baffle, and the second-stage anti-loosening assembly is arranged on the axle and located on the outer side of the first-stage anti-loosening assembly. The bridge head of the axle comprises a bridge head section, a threaded section A and a threaded section B; the first-stage anti-loosening assembly is used for preventing the bearing baffle from moving outwards along the bridge head section and comprises an anti-loosening baffle A, an anti-loosening spacer and an anti-loosening baffle B; the second-stage anti-loosening assembly is used for preventing the first-stage anti-loosening assembly from moving outwards relative to the bridge head section and comprises a bolt shaft A, a bolt shaft B, an incomplete gear A, an incomplete gear B and a pin shaft. The anti-loose locking device of the axle bridge head is reasonable in structure, can lock the axial position of a bridge head hub in a grading and progressive mode, and has higher anti-loose stability.

Description

technical field [0001] The invention mainly relates to the technical field of locking an axle head, in particular to an anti-loosening locking device for a gear type axle head. Background technique [0002] When the vehicle is running, the locking of the axle head plays a vital role in the smooth running of the wheels. In the prior art, the bridge head of the vehicle axle is usually directly locked with a nut, because the direct locking of the nut can facilitate the adjustment of the bearing clearance. However, the mode in which the nut directly locks the bridgehead in the prior art has the following disadvantages: when the wheel is running on an uneven road surface, the vibration and impact force from the road surface will easily cause the nut to loosen, which will cause the wheel hub to move slightly in the axial direction of the bridgehead of the axle. The movement of the vehicle reduces the safety and comfort of the vehicle. Therefore, it is of certain engineering valu...
