Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.
Refer to Fig. 2 to Fig. 5.Notice, appended graphic the illustrated structure of this specification, ratio, size etc., all contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
In view of flange york blank in prior art is heavier, the purchasing price of flange york blank is high; Flange york finished product is also heavier, makes the dynamic balancing effect of transmission shaft poor, is unfavorable for vehicle lightweight, is unfavorable for the energy-saving and emission-reduction of vehicle; Inventor of the present utility model designs a kind of novel flange york, by profiling groove being set on flange york base and U-shaped fork, in the bottom of flange york base, pit being set, and at the side of base, concave station is set, make flange york become the shell construction that intensity is good, weight alleviates greatly, to reduce the purchase cost of flange york blank, the dynamic balancing effect that improves transmission shaft, makes vehicle trend towards lightweight, is beneficial to the energy-saving and emission-reduction of vehicle.
Below will be elaborated to flange york of the present utility model by specific embodiment.
As shown in Figures 2 to 5, a kind of flange york 200, comprises base 210, is located at U-shaped on described base 210 fork 220, and described U-shaped fork 220 is provided with coaxially and arranges,, one group pilot hole 221 with transmission shaft being connected parallel with the bottom surface of described base 210; Described in one group, the downside of pilot hole 221 outer ends is respectively equipped with the uniform profiling groove 201 of wall thickness that connects, makes described pilot hole 221 with the bottom surface of described base 210, and the wall thickness that described profiling groove 201 makes to be supported in each sidewall of the described U-shaped fork 220 between sidewall and the described base 210 of described pilot hole 221 equates.
Wherein, the bottom center of described base 210 can be provided with a pit 211, and the sidewall of described pit 211 and the wall thickness of bottom equate.In order to make pit 211 reach maximization to the loss of weight of flange york 200, the opening of described pit 211 is made as circle.
The pitching 220 adjacent both sides with described U-shaped and can also be respectively equipped with a concave station 213 of described base 210, so that the weight of described flange york 200 is further alleviated.
Four jiaos of described base 210 of the present utility model are respectively equipped with a mounting hole 212, are used for making flange york 200 of the present utility model to be connected with the gearbox of vehicle.
The setting of the profiling groove 201 of flange york 200 of the present utility model is alleviated the weight of described flange york 200, do not affect the intensity of described flange york 200 simultaneously, profiling groove 201 can be shaped in the Forging Technology of flange york blank, shows no sign of the difficulty that increases flange york blank forging.Profiling groove 201 makes flange york blank loss of weight, thereby has reduced the purchase cost of flange york blank; Make flange york 200 finished product losss of weight, thereby improved transmission shaft dynamic balancing effect; And be conducive to vehicle lightweight.
The setting of the pit 211 of flange york 200 of the present utility model is further alleviated the weight of described flange york 200, and do not affect the intensity of flange york 200, combine with profiling groove 201 and make flange york 200 of the present utility model form the shell construction that weight is light as far as possible; And pit 211 also can be shaped in the Forging Technology of flange york blank, and do not increase the difficulty of flange york blank forging yet.Pit 211 makes the further loss of weight of flange york blank, thereby further reduces the purchase cost of flange york blank; Pit 211 also makes flange york 200 finished product losss of weight, thereby has further improved transmission shaft dynamic balancing effect, is more conducive to vehicle lightweight.
The setting of the concave station 213 of flange york 200 of the present utility model also makes the weight saving of flange york blank, in the Forging Technology of flange york blank is shaped equally, and do not increase the difficulty of flange york blank forging, thereby the purchase cost of flange york blank is reduced.In addition, the setting of concave station 213 more alleviates flange york 200 finished weights, thereby makes transmission shaft dynamic balancing better effects if, is more conducive to vehicle lightweight.
The inside angle of the profiling groove 201 of flange york 200 of the present utility model is all made as fillet, to have avoided stress to concentrate, makes flange york 200 of the present utility model not fragile in the course of the work; In addition, the corresponding position of mould that flange york blank forging of the present utility model is shaped is also made as fillet, avoid mould too thin and easily damage in profiling inside grooves angle, and also made flange york blank of the present utility model be easy to forging and molding and the demoulding.
The material of flange york of the present utility model can be selected 45 steel, and 45 steel, as common steel, make raw material of the present utility model be convenient to buying, and price are not high, thus good economy performance.
In sum, flange york intensity of the present utility model is good, lightweight, purchase cost is low, makes transmission shaft dynamic balancing effective, is conducive to vehicle lightweight.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
