Description

Flywheel falling-off prevention protection device for external bearing of axle Technical Field The utility model relates to the technical field of axles, in particular to an anti-flywheel falling protection device for an external bearing of an axle. Background The axle is a key component of an automobile chassis, is positioned between wheels and a frame and is connected with the frame through a suspension, the wheels are arranged at two ends of the axle, the axle not only bears the weight of transmitting acting forces (such as driving force, braking force, steering force and the like) in all directions between the frame and the wheels, but also supports the weight of the automobile, and different types of axles (such as a driving axle, a steering axle and a supporting axle) have specific functions, so that the running stability, the power transmission, the steering control and the like of the automobile are jointly ensured, wherein the external bearing of the axle is prevented from falling off after being connected with the flywheel, and the external bearing of the axle is required to be used for preventing the flywheel from falling off. Through investigation, china patent utility model discloses a front unpowered axle, wherein the publication number is CN215284218U, the front unpowered axle comprises an axle main body, the axle main body comprises an axle girder and two connecting ends symmetrically arranged on two sides of the axle girder, axle holes are formed in two ends of the axle girder, connecting bearings are arranged in the two axle holes, each connecting bearing comprises two directional bearings and two thrust bearings positioned below the two directional bearings, steering shafts are arranged in the two connecting bearings, the axle girder is connected with the two connecting ends through the two steering shafts, axles are fixedly arranged in the two connecting ends, and wheel bearings are arranged on the outer surfaces of the two axles. Through setting up directional bearing and thrust bearing for when the axle main part was used, directional bearing's the radial force that bears the wheel and turn to, thrust bearing's bearing bear the axial force that the wheel turned to, this design is compared traditional only one bearing, greatly reduced remote control car turn to frictional force, thereby reduces remote control car power loss and promotes the smoothness of work. The above-mentioned patent is not very convenient when the user uses, can't provide convenient to detach's effect for protection device to increased the degree of difficulty that the whole installation of structure was dismantled in the work, promoted follow-up maintenance required time, influenced the working process of follow-up work, reduced whole maintenance's efficiency, be unfavorable for the holistic long-term use of structure.
