Abstract

The purpose of the present invention is to provide a kind of lightweight low-resistance high-strength carbon fiber wheel hubs, including carbon fiber rim, spoke, aluminium alloy flower-drum, spoke is separately connected carbon fiber rim and aluminium alloy flower-drum, the two sides of aluminium alloy flower-drum are mounted on bearing tray, aperture between macropore and macropore and aluminium alloy flower-drum is set on bearing tray, silicon nitride bearing is installed, aluminium alloy axis protrudes into aluminium alloy flower-drum, and the both ends of aluminium alloy axis cooperate with the silicon nitride bearing at aluminium alloy flower-drum both ends respectively in macropore.Silicon nitride bearing of the present invention is placed in bearing tray, using interference fit between high-strength aluminum alloy axis and bearing, it ensure that silicon nitride bearing, the good detachability of high-strength aluminum alloy axis, on the one hand the primary friction converted the secondary friction between wheel shaft-axle sleeve, bearing ball and the Internal and external cycle in traditional handicraft between bearing ball and Internal and external cycle, on the other hand, the friction between traditional handicraft middle (center) bearing and axle sleeve is also eliminated, achievees the effect that reduce friction.

Description

A kind of lightweight low-resistance high-strength carbon fiber wheel hub
Technical field
The present invention relates to a kind of wheel hubs.
Background technique
The quality of carbon fiber is lighter than metallic aluminium, but intensity is higher than steel again, and has high-modulus, corrosion resistant characteristic, There is extensive utilization in defence and military and civilian aspect;
Wheel hub is divided into integral type wheel hub and Split type wheel hub, and wherein Split type wheel hub includes, flower-drum, spoke, steel ring, axis It holds, axle sleeve, material is generally quality larger alloy aluminum or stainless steel;Traditional integral type wheel hub is designed without tray, axis Hold not easy to disassemble, while axle sleeve outside axle generates secondary friction;
Currently, concentrating on the transformation of bearing, the utilization of lubricating oil, organism material for the research for reducing the friction of wheel hub nocuousness Selection, the research of the rare harmful friction for reducing wheel hub from the angle of Design of Mechanical Structure;
In summary, it is known that existing wheel hub is difficult to meet the needs of to low-resistance, lightweight, high intensity.
Summary of the invention
The purpose of the present invention is to provide a kind of lightweight low-resistance high-strength carbon fiber wheels for reducing the whole harmful friction of wheel hub Hub.
The object of the present invention is achieved like this:
A kind of lightweight low-resistance high-strength carbon fiber wheel hub of the present invention, it is characterized in that: including carbon fiber rim, spoke, aluminium conjunction Golden flower drum, spoke are separately connected carbon fiber rim and aluminium alloy flower-drum, and the two sides of aluminium alloy flower-drum are mounted on bearing tray, axis Aperture between macropore and macropore and aluminium alloy flower-drum is set on tray, silicon nitride bearing, aluminium alloy axis are installed in macropore It protrudes into aluminium alloy flower-drum, the both ends of aluminium alloy axis cooperate with the silicon nitride bearing at aluminium alloy flower-drum both ends respectively.
The present invention may also include:
1, the corresponding bearing tray interference fit of each silicon nitride bearing, the both ends of aluminium alloy axis are right with it respectively The silicon nitride bearing interference fit answered.
2, carbon fiber rim, spoke and aluminium alloy flower-drum are combined integral by way of the die casting in mold.
3, the diameter of the aperture between the macropore of bearing tray and aluminium alloy flower-drum is less than silicon nitride bearing diameter of bore, aluminium Alloy axis is the stepped shaft structure for preventing silicon nitride bearing play.
Present invention has an advantage that invention removes in traditional handicraft axle sleeve contact, both ensure that silicon nitride bearing, The good detachability of high-strength aluminum alloy axis, on the one hand by wheel shaft-axle sleeve, bearing ball and the Internal and external cycle in traditional handicraft it Between secondary friction be converted into the primary friction between bearing ball and Internal and external cycle, on the other hand, also eliminate in traditional handicraft Friction between bearing and axle sleeve achievees the effect that reduce friction;The wheel body of the high-strength carbon fiber wheel hub is by carbon fibre material Production, directly by wheel body die casting on the flower-drum of alloy aluminum, in the case where improving wheel hub intensity, it is light-weighted to realize wheel hub Purpose.It has installed bearing tray between high-strength aluminum alloy flower-drum and silicon nitride bearing additional, has greatly facilitated Wheel maintenance replacement Work;Bearing tray concave bearing hole hole diameter is less than silicon nitride bearing diameter of bore, convenient to high-strength aluminum alloy flower-drum Interior silicon nitride bearing is replaced and is cleaned;High-strength aluminum alloy axis is designed using multi-diameter shaft, prevents bearing play.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is aluminium alloy flower drum partial schematic diagram;
Fig. 3 is aluminium alloy axis schematic diagram;
Fig. 4 is the whole installation diagram of the present invention.
Specific embodiment
It illustrates with reference to the accompanying drawing and the present invention is described in more detail:
In conjunction with Fig. 1-4, a kind of lightweight low-resistance high-strength carbon fiber wheel hub of the present invention, by carbon fiber wheel body 1 and hub centre Part 2 carries out die casting processing in mold, makes it combine as entirety;Two side bearing trays 5 are used with high-strength aluminum alloy flower-drum 4 It is bolted, silicon nitride bearing 3 and bearing tray 5 are interference fitted, and high-strength aluminum alloy axis and silicon nitride bearing 3 are interference fitted. The making material of carbon fiber wheel body 1 is carbon fiber.The making material of high-strength aluminum alloy flower-drum 4 is 7075 aluminium alloys.Bearing is held The making material of disk 5 is 7075 aluminium alloys, and concave bearing hole hole diameter is less than bearing bore diameter.The system of high-strength aluminum alloy axis Make 7075 aluminium alloy of material, multi-diameter shaft design prevents bearing play.The model silicon nitride 6802Z of silicon nitride bearing 3.Bolt Model in hexagonal A2-70.
