Description
Technical Field
The utility model relates to an axle, a high life axle wheel end assembly specifically says so.
Background
With the increasing demands of customers for the long service life of commercial vehicle components, we are forced to develop an axle wheel end assembly which can prolong the service life and is convenient for after-sales maintenance, so as to meet the demands of customers. At present, after 5000Km of an axle wheel end assembly is first protected, maintenance is needed once every 1.5-2 ten thousand Km, the service life is 8-10 ten thousand Km, and maintenance is needed once every two months. When the axle wheel end assembly is maintained, the bearing and the oil seal are easy to fall off to cause damage, and the service life of the axle wheel end assembly is easy to be shortened due to pollution, insufficient torque or over-adjustment and the like under the influence of environment and the skill of operators.
Disclosure of Invention
In order to solve the problem, the utility model aims at providing a high life axle wheel end assembly.
The utility model discloses a realize above-mentioned purpose, a high life axle wheel end assembly, the wheel hub bearing, assemble preceding wheel hub's bearing room, the wheel hub bearing passes through the oil blanket fixedly, the wheel hub bearing passes through lock washer, the knuckle nut, the jump ring is fixed, the ring gear pressure equipment is to preceding wheel hub on, the brake drum passes through the wheel hub bolt and is connected with preceding wheel hub, the whole assembly unit of constitution assembles knuckle axle footpath and oil seal seat circle through the knuckle nut, the knuckle nut passes through the dog and is connected with the knuckle, the dog passes through locking ring back connection to the knuckle nut on. The front wheel hub cover is connected with the front wheel hub through a bolt to form a complete axle wheel end assembly.
The inner bearing end of the utility model is limited by the oil seal inner measuring lip; the outer bearing, the locking gasket and the outer end of the steering knuckle nut with the torque fixing function are fixed by a clamp spring; the dustproof cover is arranged between the crotch parts of the two bearing holes of the hub, so that external impurity pollution is guaranteed, and the bearing lubricating grease can be kept sufficient. The newly developed axle wheel end assembly adopts an integral structure with integrally assembled and disassembled parts, and the knuckle nut with the fixed-torque function can ensure that the axle wheel end assembly has better performance and meets the requirements of the whole vehicle.
Drawings
The present invention will now be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, a long-life axle wheel end assembly comprises a steering knuckle 1, a front wheel hub 9 and a brake drum 18, wherein the steering knuckle 1 supports the front wheel hub 9 through an inner wheel hub bearing 8 and an outer wheel hub bearing 11, an O-shaped sealing ring compacted through an oil sealing seat ring 3 is sleeved on the steering knuckle 1 at one side of the inner wheel hub bearing 8, an oil seal 6 for sealing and fixing the inner wheel hub bearing 8 is sleeved on the oil sealing seat ring 3, the outer wheel hub bearing 11 is fixed on the outer end of the front wheel hub 9 through a locking gasket 13, a steering knuckle nut 14 and a clamp spring 12, the steering knuckle nut 14 is connected with the steering knuckle 1 through a stop block 4, a front wheel hub cover 16 for covering the locking gasket 13, the steering knuckle nut 14 and the clamp spring 12 is covered on the stop block 4, the front wheel hub cover 16 is fixed on the outer end of the front wheel hub 9 through a bolt 17 and a front wheel hub cover gasket 15, the brake drum 18 fixed through a wheel hub bolt 19 and, the outer side wall of a front hub 9 in the brake drum 18 is also provided with a gear ring 7 in a pressing mode, an annular dust cover 10 is further clamped on the steering knuckle 1 between the inner hub bearing 8 and the outer hub bearing 11, the dust cover 10 is an upper closed cavity and a lower closed cavity, and openings of the two cavities are respectively aligned with the inner hub bearing 8 and the outer hub bearing 11 on two sides.
The utility model discloses an axle wheel end assembly bearing (be inner hub bearing 8 and outer hub bearing 11) roller adopts the logarithmic curve design, and oil blanket 6 adopts the box-type structure that has the multichannel sealing lip, has reduced the rotation resistance of axle wheel end assembly when the loading; the inner side, the middle side and the outer side of the axle wheel end assembly have dustproof functions, the inner side of the assembly has double sealing functions by virtue of a box-type oil seal 6 and an O-shaped sealing ring 2, the middle part of the assembly has a sealing function by virtue of a dust cover 10, and the outer side of the assembly has a sealing function by virtue of a front hub cover gasket 15 and a front hub cover 16; the assembly is mainly characterized in that the integrally assembled and disassembled parts are not separated, thereby effectively preventing the pollution of external impurities to the bearing, simultaneously keeping the lubricating grease from losing and meeting the lubricating requirement of the bearing; the other remarkable characteristic of the assembly is that the fastening torque of the steering knuckle nut 14 is guaranteed by design and is not influenced by external factors, when the axle wheel end assembly reaches the optimal working state, the steering knuckle nut 14 automatically loses efficacy after the torque is stable, the axial force is not changed any more, the problem that parts of the axle wheel end assembly are damaged due to the fact that the fastening torque is too large or too small can be solved, and the axle wheel end assembly is guaranteed to meet the requirements of long service life and easiness in maintenance.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
