The specific embodiment
Below in conjunction with drawings and embodiments the utility model is further specified.
See also Fig. 1 to Fig. 2, golf cart front driving axle steering hardware includes: the mounting bracket 1 of steering swivel, steering swivel 2, Hub assembly 100 and connect the mounting bracket 1 of described steering swivel and the stub device 3 of steering swivel 2; The front-wheel of the described golf cart of described Hub assembly 100 fixed installations, the mounting bracket 1 of described steering swivel is fixed on the front driving axle of described golf cart; Described steering swivel 2 is between the mounting bracket 1 and Hub assembly 100 of steering swivel, described steering swivel 2 is connected and fixed rigidly with Hub assembly 100, described stub device 3 can be used as between the mounting bracket 1 of steering swivel 2, Hub assembly 100 and described steering swivel S. A. in relative rotation, and the rotation centerline that steering swivel 2 and Hub assembly 100 rotate is the line of centers of described stub device 3; Wherein, the stub 30 of described stub device 3 is provided with the oil hole 31 that is positioned on the outermost face and the grease storage chamber 32 of stub, grease is injected by oil hole 31, in grease storage chamber 32, store, and be filled in the gap in connecting portion zone of the mounting bracket 1 of described steering swivel and steering swivel 2, and in the described stub device 3 in-to-in gaps.
Described stub device 3 includes "T"-shaped stub 30, is positioned at the zerk 9 of oil hole 31 ports, one or more pad, be socketed in stub 30 peripheries axle sleeve 6, be positioned at the nut 8 with oil hole 31 relative sides.
Described grease storage chamber 32 is the circular groove with described oil hole 31 internal communication.
The mounting bracket 1 of described steering swivel and steering swivel 2 are provided with stub device mounting hole 10,20, stub 30 passes the mounting bracket mounting hole 10 of steering swivel mounting hole 20 and steering swivel successively, and nut 8 is tightened on the other end of mounting bracket that stub 30 stretches out steering swivel; Axle sleeve 6 is nested in the periphery of stub 30 in the steering swivel mounting hole 20, and the two sides of steering swivel 2 is equipped with the thrust washer 5,7 that is socketed in axle sleeve 6 peripheries; The outside of described thrust washer 5 also includes a stub pad 4.
As shown in Figure 1, the effect of Hub assembly 100 mainly is to support front driving axle by wheel, and the propulsive effort of front driving axle is passed to wheel, so the structural strength of Hub assembly 100 has than higher requirement, scantling of structure is bigger.This steering hardware is in the wheel rim inside of wheel, because the wheel rim space is less, Hub assembly 100 is bigger again, does not have parts such as space mounting stub 30, zerk 9.Therefore, need add the big wheel specification, the wheel rim inner space is increased.Giant tyre can increase the carrying capacity and the off-road capability of vehicle, and the transmitting ratio that adds the vehicle behind the big wheel on the other hand guarantees constant by changing the gear case number of teeth.
In Fig. 2, the structure of stub 30 is improved on original basis, bores an oil storage blind hole at its top, and is used for refueling at top installation zerk 9.The circular groove of face of cylinder processing that cooperates with axle sleeve 6 on stub 30 makes circular groove be communicated with the oil storage blind hole.Like this, the grease of squeezing into from zerk 9 can pass through the oil storage blind hole, circular groove arrives the gap of stub 30 and axle sleeve 6, reaches lubricated purpose.
In Fig. 2, stub 30 forms assembling integral body with support 1 by nut 8, and stub 30 is spacing with support 1 by its convex shoulder.Axle sleeve 6 is pressed in the mounting hole of steering swivel 2, and thrust washer 5, thrust washer 7 are pressed into axle sleeve 6 respectively, and steering swivel 2 is clamped, and therefore, steering swivel 2, thrust washer 5, axle sleeve 6, thrust washer 7 form an assembling integral body.Like this, turning joint of two the whole formation of assembling, and matching relationship is a free-running fit, and the gap mainly contains between axle sleeve 6 and the stub 30, between thrust washer 5 and the stub pad 4, between thrust washer 7 and the support 1, fill the grease that zerk 9 is pressed in the gap.
As shown in Figure 1, golf cart front driving axle steering hardware has two above-mentioned turning joints, the torque loads that ground passes over by wheel can be changed into vertically, laterally and the application force load of vertical direction.So the power that each turning joint bears is respectively vertical, horizontal horizontal force and horizontal impact, and the vertical power of vertical direction and vertical impact, wherein, axle sleeve 6 bears the power and the impact of horizontal direction, and thrust washer 5, thrust washer 7 bear the power and the impact of vertical direction.Load-carrying capacity is big, friction coefficient is little and the abrasion resistant material for sliding bearing so axle sleeve 6, thrust washer 5 and thrust washer 7 adopt, and makes whole turning joint rotate light, long service life.
Above-mentioned listed specific implementation is nonrestrictive, and to one skilled in the art, in not departing from the utility model scope, various improvement and the variation carried out all belong to protection domain of the present utility model.
