Abstract

A universal wheel with a plastic wheel fork comprises the plastic wheel fork, two wheel fork bearings, a round head bolt, a nut, a lock bolt and a PU (polyurethane) wheel with two bearings at the hole center. The universal wheel is characterized in that two counter bored holes are arranged above and below the top of the plastic wheel fork respectively, a through hole is arranged between the upper counter bored hole and the lower counter bored hole of the plastic wheel fork, mutually-communicated holes are arranged on two wheel forks at the lower end of the plastic wheel fork, a wheel fork bearing is embedded in each of the upper counter bored hole and the lower counter bored hole of the plastic wheel fork respectively, the round head bolt penetrates into inner holes of the two wheel fork bearings, the nut is screwed on the round head bolt penetrating into the inner holes of the two wheel fork bearings, the lock bolt comprises a screw cylinder and a bolt, and the screw cylinder penetrates into the mutually-communicated holes and two inner holes of bearings of the PU wheel to be screwed with the bolt. The universal wheel with the plastic wheel fork after assembly can use a screw rod screwed on the round head bolt in two wheel fork bearing holes at the top of the plastic wheel fork to be connected with a recreational vehicle.

Description

The cardan wheel of plastics wheel fork

Technical field

The present invention relates to a kind of recreational vehicle cardan wheel, particularly a kind of cardan wheel of plastics wheel fork of wheel fork made of plastic.

Technical background

The wheel fork of the cardan wheel that the recreational vehicle that can see is in the market used generally all is (or iron or aluminium) of metal, and this has just brought certain restriction, or smooth not on the profile, or surface treatment is not ideal enough.

Summary of the invention

The objective of the invention is to provide that a kind of profile is smooth, rational in infrastructure, the cardan wheel of the more simple plastics wheel fork of production technology.The object of the present invention is achieved like this: the cardan wheel of plastics wheel fork, comprise the plastics wheel fork, the two-wheeled fork bearing, one round head bolt, one nut, the PU wheel of a pair of lock bolt and a hole heart band two bearings, it is characterized in that: plastics wheel fork top a counterbore respectively arranged up and down, between the upper lower counterbore of plastics wheel fork a through hole is arranged, have mutual to perforation on two wheel forks of plastics wheel fork lower end, respectively inlay in the upper lower counterbore of plastics wheel fork and take turns fork bearing, penetrate a round head bolt in the endoporus of two-wheeled fork bearing, penetrate to twist on the round head bolt in the two-wheeled fork bearing endoporus and connect a nut, the lock bolt is comprised barrel and bolt, barrel penetrate plastics wheel fork two-wheeled fork mutual in the perforation and in the two bearings endoporus of PU wheel, twist with bolt and barrel again and connect; Assemble the cardan wheel of complete plastics wheel fork, can connect with the screw rod that is fastened to the round head bolt in the two-wheeled fork bearing hole, plastics wheel fork top, with recreational vehicle.

The invention has the beneficial effects as follows: the present invention adopts the plastics wheel fork with the wheel fork of cardan wheel, solved problem of appearance, surface treatment problem and the production technology problem of cardan wheel wheel fork, than common cardan wheel, production technology is simpler, cost is lower, and appearance effect is better; Plastics wheel fork top respectively is provided with up and down a counterbore, respectively inlay in the upper lower counterbore of plastics wheel fork and take turns fork bearing, penetrating with a round head bolt in the endoporus of two-wheeled fork bearing, and twisting connected nut, so that only inlaying a bearing with common cardan wheel top, the present invention compares, intensity is better, performance better, more stable.
