Front wheel connection disc of dune buggy

Abstract

The invention relates to a dune buggy front wheel connecting disk which is provided with an axle hole matched with a knuckle spindle, the axial end of the connecting disk used for connecting with a hub is provided with four threaded studs which are positioned around the axle hole and evenly arranged, and the other axial end thereof is evenly provided with three screwed holes around the axle hole.The dune buggy front wheel connecting disk is characterized in that the axial end surface surrounding axle hole of the connecting disk used for connecting with the hub is provided with a locating lugboss matched with a hub center hole, and the locating lug boss is positioned between the four threaded studs and the axle hole. After the hub and the connecting disk are connected and located, the invention ensures the radial location of the hub is better and the motion of the hub is steadier and does not shift or bounce.

Description

technical field [0001] The invention relates to a front wheel suspension device of an ATV, in particular to a front wheel connection plate of an ATV. Background technique [0002] The ATV is a four-wheel motorcycle with all road conditions. The hub of the front wheel of the ATV is connected to the front wheel drive shaft through the connecting plate connected to the hub. Since there are four studs fixedly arranged on the connecting plate, the connecting plate is inserted into four through holes on the wheel hub at the same time through these four studs and fastened with nuts, because the four fixed studs on the connecting plate must be connected at the same time. Insert into the four through holes with fixed positions on the hub. This simultaneous four-positioning assembly method is not easy to align the four studs with the four holes at the same time during assembly, resulting in over-positioning, which increases the difficulty of assembly. In the design, the hole diameter...

Problems solved by technology

Since there are four studs fixedly arranged on the connection plate, the connection plate is inserted into four through holes on the wheel hub at the same time through these four studs and fastened with nuts, because the four fixed studs on the connection plate must be connected at the same time. Insert into the four through holes with fixed positions on the hub. This simultaneous four-position assembly method is not easy to align the four studs with the four holes at the same time during assembly, resulting in over-positioning, which increases the difficulty of assembly. In the design, the hole diameter will be enlarged to increase the fit gap between the hole and the stud, and due to the increase of the fit gap between the hole and the stud, the connection between the hub and the connecting plate is prone to radial displacement and centering deviation, thus This causes radial shaking and jumping of the ATV under driving vibration, which reduces the driving stability of the front wheel of the ATV and makes the wheel hub easy to be scratched by the ball head of the steering rod
