By car set hypoid rear axle with
hypoid final pair (Fig. 100) consisting of
three main parts.
A. Carter (beams), collected from two of the stamped
steel sheet and the two halves of forged flanges, fastened
Arc welding of tube ends of the beams. Average Premium
part of the beam has a through hole, the back side of which
hermetically welded (rexinforcing the crankcase), stamped from sheet
have a spherical cap, which houses the serving of
the main transmission part of the driven gear with the differential.
The front end, shaped and rexinforced inside with steel
plates, used for fastening the rear of the main transfer
At a distance of approximately 455 mm from the center of the crankcase
welded to the supporting platform-cushion
Two. Main gear rear axle with hypoid gears having
for the car - 3.91 (38 and nine teeth);
for a van and a pickup truck - 4.22 (41 and nine zubev).
A characteristic design feature of hypoid final
transfer the axis is shift gears and housing cap
relative to the driven gear down to 32 mm and 11 mm
right relative to the longitudinal axis of the vehicle.
Three. Axes (polurazgruzhennogo type) in the collection, representing
a site built with oil trap, with radial ball
bearing, means of forced and locked on the half-shut-off
sleeve napressovyvaemoy in a heated (to a temperature of 250-300 ° C)
Bearing half closed with a one-time initiation of
lubricant lifetime before major
car repairs. The free end of a half-involute
slots and mates with the pinion axis, set in a box
differential final drive.
The second end of the half with a flange, which is based on the bearing,
retained in the socket housing flange with steel plates,
presses the outer ring of the bearing outer diameter
which is centered brake pads shield. A plate with
with brake shield is attached to the end flange with four bolts.
Attached to the flange axis brake drums and wheels.
In the operation of a vehicle moving parts and assemblies
rear axle are subject to wear, that over time begins to
affect the performance of the entire transmission and the bridge itself.
The nominal dimensions, tolerances, clearances, and tightness in the main
mating parts sites, most often subject to wear,
are shown in Table. 12.
