Abstract
The utility model discloses a rear axle hub for an electric-wheeled dumper, which belongs to the technical field of rear axle hubs of electric-wheeled dumpers and comprises a hub in an integral cylindrical structure. The left end face of the hub is provided with a retainer ring groove, an oil filling hole is radially arranged beside the retainer ring groove, a left bearing mounting groove, an internal spline and a right bearing mounting groove are arranged from left to right on the trapezoidal inner wall of the hub, a round groove and a square groove are axially arranged on the outer wall of the hub, the outer wall of the hub is provided with a 28-degree slope, a left threaded hole is peripherally arranged on the left end face of the hub, and a right threaded hole is arranged on the right end face of the hub. The rear axle hub for the electric-wheeled dumper has the advantages that the hub not only has the function of mounting of normal rims but also can be used as a casing of a wheel speed reducer for bearing and connecting, so that the rims can be mounted in a simpler manner, and a certain space is saved. Moreover, the hub can be thickened to better meet requirements of an integral vehicle on the wheel speed reducer.
Description
Technical field
The utility model relates to a kind of wheel hub, relates in particular to a kind of electric power wheel self-discharging vehicle back axle wheel hub, belongs to electric power wheel self-discharging vehicle back axle hub technology field.
Background technology
Day by day the maximization of quarry tipper makes the electric drive wheel quarry tipper obtain widespread use.Usually, the wheel hub of electric drive wheel quarry tipper passes through bolted connection on the wheel reduction gear shell.Because electric drive wheel quarry tipper tonnage is big, work under bad environment, the bolted wheel hub of this employing is difficult to satisfy the demand in intensity, reliability and service life.Simultaneously, its mounting structure relative complex, wheel reduction gear shell and wheel hub are two parts, required installing space is bigger.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of electric power wheel self-discharging vehicle back axle wheel hub, can effectively address the above problem.
To achieve these goals, the technical scheme of the utility model employing is: a kind of electric power wheel self-discharging vehicle back axle wheel hub comprises wheel hub; Wheel hub is the integral structure of rounded cylindrical, and its left side has circlip groove, and oil hole is radially offered on the circlip groove next door; The inwall of wheel hub is a trapezium structure; Have left bearing mounting groove, female splines and right bearing mounting groove from left to right, the outer wall of wheel hub has 28 degree inclined-planes, and symmetry is offered circular groove and square groove vertically; Wheel hub left side circumference is established the left-hand thread hole, and the right-hand thread hole is established in the right side.
Wherein, wheel hub is a cast-in-block, and the circlip groove on the wheel hub, oil hole, bearing installation groove, square groove, female splines, bearing installation groove, circular groove, inclined-plane, tapped bore and tapped bore are processed after being and casting.
The beneficial effect of the utility model is: this kind wheel hub not only satisfies the function that general wheel rim is used to install wheel hub, also simultaneously as the shell of wheel reduction gear, plays and carries and the bonded assembly function.This multi-functional wheel hub combines the dual-use function of wheel reduction gear shell and wheel hub, makes that the mounting means of wheel rim is more simple, and simultaneously, owing to saved certain space, the thickness of wheel hub can increase, and has satisfied the requirement of car load to wheel reduction gear better.
