Abstract
The invention provides a drive axle semi-shaft which comprises a semi-shaft body and a hub. The hub and the semi-shaft body are of a key connection mode structure. A nut locks the hub from one end. The key connection structure connects the semi-shaft body without a flange plate and the hub. Flange hubs of any size can by combined according to the requirements, a structure capable of transmitting torque and allowing a rim tire to be installed is formed, and therefore the portion in the direction, perpendicular to the semi-shaft body, of the outer circumference of the hub is provided with a step matched with a rim. The side wall formed by the step is connected with the inner wall of the rim. The inner wall of the rim and the side wall of the hub are compressed, connected and assembled into one through a bolt and a nut. The drive axle semi-shaft has the advantages that the structure is reasonable, manufacturing and processing are convenient and fast, the process is simple, the semi-shaft can be formed by directly processing and treating bars and plates in a heat mode, a mould is not needed for forging the flange plate, the manufacturing and processing cost is low, the manufacturing efficiency is greatly improved, connection is convenient, safe and reliable, the structural strength is good, and use and maintenance are convenient.
Description
Technical field
The present invention relates to technical field of engineering machinery, particularly a kind of half shaft.
Background technology
Traditional half shaft is to adopt flange and axle integral structure, as shown in Figure 1, when making, first raw material need be forged through mould, pier goes out the flange of prescribed level, then flange and axis body are processed, manufacturing process complexity, difficulty of processing is high, as flange size changes, need mfg. moulding die again, the working service inconvenience of the poor and part of commonality.
Summary of the invention
Object of the present invention is just to provide a kind of easy making process of manufacturing, technique is simple, can directly form with bar and Sheet Metal Processing after-baking, forge pier flange without mould, can be according to the synthetic arbitrary size flange wheel hub of requirement groups, making tooling cost is low, easy to connect, safe and reliable, structural strength is good, and working service is half shaft easily.
Solution of the present invention is such:
A kind of half shaft, comprise wheel hub and semiaxis, described half-axile sleeve is connected to wheel hub, described wheel hub and semiaxis adopt key connection mode, described semiaxis outer end is formed with the screw thread pair matching with nut, lock wheel hub by nut from one end, wheel hub is connected with half shaft locking of flanged dish not, for transmitting torque and structure that wheel rim tire is installed; Described wheel hub excircle becomes vertical direction to be formed with the step coordinating with wheel rim with semiaxis, sidewall and wheel rim inwall that this step forms join, and wheel rim inwall and the connection of wheelboss side wall compression is integrated with bolt and nut.
Technical scheme also comprises more specifically: described key connection structure comprises that semiaxis circumferential periphery forms spline or the flat key of chimeric supporting wheel hub, and the spline that described wheel hub and semiaxis circumferential periphery form or flat key form movable connection method.
Further: the described wheel hub position corresponding with the mounting hole of wheel rim has bolt mounting holes, for installing the bolt of wheel rim inwall and wheelboss side wall compression.
Further: described boss bolt mounting hole is provided with the block rotating for limiting bolt at bolt end place.
Further: described boss bolt attachment face is sink deck, the restriction face that the sidewall of sink deck is described block.
Advantage of the present invention is rational in infrastructure, make easy making process, technique is simple, can directly form with bar and Sheet Metal Processing after-baking, forges pier flange without mould, can be according to the synthetic arbitrary size flange wheel hub of requirement groups, making tooling cost is low, greatly improves make efficiency, easy to connect, safe and reliable, structural strength is good, and working service is convenient.
Accompanying drawing explanation
Fig. 1 is conventional flange axle integral structure schematic diagram.
Fig. 2 is structural representation of the present invention.
The specific embodiment
the present invention comprise wheel hub 102 and semiaxis 101, described semiaxis 101 is socketed with wheel hub 102, described wheel hub 102 adopts spline joint with semiaxis 101, described semiaxis 101 outer ends are formed with the screw thread pair matching with nut 103, locked wheel hub 102 from one end by nut 103, wheel hub 102 and the semiaxis 101 of flanged dish are not locked and be connected, for transmitting torque and structure that wheel rim tire is installed; Described wheel hub 102 excircles are formed with 101 one-tenth vertical direction of semiaxis the step coordinating with wheel rim, and sidewall and wheel rim inwall that this step forms join, and wheel rim inwall and wheel hub 102 side wall and pressure stressed joints are installed as to one with bolt 104 nuts 105.
Described wheel hub 102 position corresponding with the mounting hole of wheel rim has bolt mounting holes, for installing the bolt 104 of wheel rim inwall and wheel hub 102 sidewalls compressions.
Described wheel hub 102 bolt attachment faces are sink deck, the sidewall of sink deck is to limit the restriction face that bolt rotates, after bolt 104 is in place, this restriction face joins with bolt cap, bolt 104 can not be rotated, wheel rim inwall and wheel hub 102 side wall and pressure stressed joints can be installed as to one at the direct fastening nut 105 of bolt 104 external part.
