Abstract
The utility model relates to a front axle wheel hub of a vehicle. Through improving weight reduction grooves on the breadth of the wheel hub, resonance phenomena among the weight reduction grooves can be avoided, and the entire intensity of the wheel hub can be enhanced. In the front axle wheel hub of the vehicle, the breath of the wheel hub is provided with a plurality of weight reduction grooves. The front axle wheel hub of the vehicle is characterized in that the weight reduction grooves are long groove type weight reduction grooves and short groove type weight reduction grooves, and the long groove type weight reduction grooves and the short groove type weight reduction grooves are alternately distributed on the breath of the wheel hub; optimally, the number of the long groove type weight reduction grooves is five, and the number of the short groove type weight reduction grooves is five; the long groove type weight reduction grooves are diamond grooves, and the short groove type weight reduction grooves are dovetail grooves; and the length of each short groove type weight reduction groove is 0.5 to 0.8 times of the length of each long groove type weight reduction groove. The utility model further provides a front axle wheel hub assembly of a vehicle.
Description
Technical field
The utility model relates to a kind of automobile-used wheel hub, relates in particular to a kind of car front axle wheel hub structure and Hub assembly.
Background technology
In, heavy truck, passenger vehicle vehicle be widely used in road transport and engineering transportation; Automotive hub is as an important transmission link between ground and the vehicle body; Its load-carrying capacity has determined the load-carrying capacity of car load, and its weight affects the economy requirements such as oil consumption of car load.Under commercial vehicle/comm..vehicle weight-saving overall background, satisfy under the prerequisite of load-carrying capacity requirement, its weight is lighter just to have superiority more.There is the problem that weight is bigger than normal, structure is heavy in order to solve the wheel hub product; Generally the hub radius direction is offered a plurality of loss of weight grooves in order to alleviate wheel hub weight in wheel hub breadth upper edge; Yet because loss of weight groove shape size is identical; Can produce resonance effect between the adjacent loss of weight groove, the whole wheel hub insufficient strength has been brought potential safety hazard to car load.
The utility model content
To deficiency of the prior art, the utility model aims to provide a kind of car front axle wheel hub, through the loss of weight groove on its breadth is improved, can avoid the resonance effect between each loss of weight groove, improves the bulk strength of wheel hub.The utility model also provides a kind of car front axle Hub assembly for this reason.
In order to address the above problem; The utility model provides a kind of car front axle wheel hub; This wheel hub breadth is provided with a plurality of loss of weight grooves; This car front axle wheel hub is characterised in that: said loss of weight groove comprises trough type loss of weight groove and short grooved loss of weight groove, and trough type loss of weight groove and short grooved loss of weight groove arranged alternate are on the wheel hub breadth.
Preferably, the quantity of said trough type loss of weight groove is five; The quantity of said short grooved loss of weight groove is five.
Preferably, said trough type loss of weight groove is the rhombus groove; Said short grooved loss of weight groove is a dovetail groove.
Preferably, the slot length of said short grooved loss of weight groove is 0.5 to 0.8 times of slot length of said trough type loss of weight groove.
The utility model also provides a kind of car front axle Hub assembly; Comprise wheel hub, wheel rim and plate disc brake; The outer ring flange of said wheel hub is connected with wheel rim, and the inner ring flange is connected with plate disc brake, and this car front axle Hub assembly is characterised in that: said wheel hub is above-mentioned car front axle wheel hub.
Through the loss of weight groove of two kinds of different lengths of separation on the breadth of wheel hub, this separation helps avoiding resonance; Simultaneously guarantee the wall thickness even transition proof strength time, reduced stress concentration, avoided problems such as casting shrinkage porosite from technology from structure.
Description of drawings
Fig. 1 is the main TV structure scheme drawing of the car front axle wheel hub of the utility model;
Fig. 2 is the perspective view of the car front axle wheel hub of the utility model;
Fig. 3 is the structural representation of the car front axle Hub assembly of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
In conjunction with Fig. 1 and Fig. 2; A kind of car front axle wheel hub of the utility model; This wheel hub breadth is provided with a plurality of loss of weight grooves, and the loss of weight groove comprises five trough type loss of weight groove A and five short grooved loss of weight groove B, and the slot length of trough type loss of weight groove A is slightly longer than the slot length of short grooved loss of weight groove B.Trough type loss of weight groove A is alternate with each other with short grooved loss of weight groove B, be arranged on the wheel hub breadth equably.The loss of weight groove of this separation different structure helps avoiding resonance; Simultaneously guarantee the wall thickness even transition proof strength time, reduced stress concentration, avoided problems such as casting shrinkage porosite from technology from structure.Preferably, in order to avoid resonance better, improve the overall mechanical strength of wheel hub simultaneously, said trough type loss of weight groove A is the rhombus groove, and promptly the surface of groove A is a rhombus; Said short grooved loss of weight groove B is a dovetail groove, and promptly the surface of groove B is trapezoidal.The slot length of said short grooved loss of weight groove B is 0.5 to 0.8 times of slot length of said trough type loss of weight groove A.
Fig. 3 is the structural representation of the car front axle Hub assembly of the utility model.This Hub assembly comprises above-mentioned wheel hub 1, wheel rim and plate disc brake 2, and the outer ring flange of said wheel hub 1 is connected with wheel rim, and the inner ring flange is connected with plate disc brake 2.The axle load of described suitable car front axle is between 5 tons to 11 tons.The profile upperlimit of said wheel hub is between between the 300mm to 450mm.Described outer ring flange diameter is between between the 270mm to 400mm, and the bolt quantity on this outer ring flange is between 8 to 12.Described inner ring flange diameter is between between the 150mm to 250mm, and the bolt quantity on this inner ring flange is between 8 to 12.The wheel hub of the utility model is a cast structure, and load-carrying capacity is strong, and has opened the loss of weight groove in position, has alleviated the weight of structure effectively.
