Abstract
The utility model belongs to the field of automobile differential mechanism assembly forging technologies and particularly discloses an improved automobile differential mechanism flange forging blank which comprises a differential mechanism body, a first through hole, a second through hole, a third through hole, a fourth through hole, a circular protruding shaft sleeve, a circular groove shaft sleeve and a fifth through hole. The differential mechanism body, the first through hole, the second through hole, the third through hole, the fourth through hole, the circular protruding shaft sleeve, the circular groove shaft sleeve and the fifth through hole are formed at one shot through forged round steel or square steel in a forging mode. The improved automobile differential mechanism flange forging blank has the advantages that the differential mechanism flange blank is formed in an integrated mode at production time, so that subsequent secondary finish machining procedure is eliminated, production efficiency is improved, and assembly is simple; the produced differential mechanism flange blank is designed to be in an concave face shape, so that production materials are saved, service life is ensured, and safety coefficients and operation working efficiency are improved. Moreover, the improved automobile differential mechanism flange forging blank is low in production cost and easy to popularize.
Description
Technical field
The utility model belongs to automobile differential assembly technical field of forging, is specifically related to a kind of improved automotive differential mechanism flange forging blank.
Background technique
Known from institute, automobile differential is device important in automobile assembling work, and it specifically plays transmitting torque, adjusts the effect of various transmission shafts, and makes perfectly cooperation between various component, thereby makes automobile advance middle acquisition power; And in the composition of differential mechanism, the differential mechanism flange plays important effect especially, and it is the tie that connects between truck drive shaft and back axle, has to connect and the effect of transferring power, so that the differential mechanism flange directly can embody the differential mechanism performance is excellent or bad.
Its four edges of differential mechanism flange blank that the employing prior art is forged all is set to straight line, adds the not only low use that has also increased the production material of manufacturing efficiency in man-hour in enterprise, and then increases the cost of production input of enterprise; Simultaneously when the assembly connection transmission shaft also under more loaded down with trivial details and working state efficient low.
Therefore, based on the problems referred to above, the utility model provides a kind of improved automotive differential mechanism flange forging blank.
The model utility content
The model utility purpose: the purpose of this utility model is for the deficiencies in the prior art, a kind of improved automotive differential mechanism flange forging blank is provided, guarantee that on the one hand differential mechanism flange end product quality and working life, reduction manufacture cost drop into, save on the other hand manufacturing procedure and installation time, improve the operation working efficiency of differential mechanism flange.
Technological scheme: a kind of improved automotive comprises differential mechanism body, the first through hole, the second through hole, third through-hole, fourth hole, circular protrusions axle sleeve, circular groove axle sleeve and fifth hole with differential mechanism flange forging blank; Described the first through hole, the second through hole, third through-hole and fourth hole are symmetricly set in respectively four jiaos of differential mechanism body interior; Described differential mechanism body sets gradually circular protrusions axle sleeve, circular groove axle sleeve and fifth hole from outside to inside, and wherein circular protrusions axle sleeve one side is protruded the differential mechanism body; Connect by level and smooth gradient junction surface between described circular protrusions axle sleeve and circular groove axle sleeve; Described differential mechanism body, the first through hole, the second through hole, third through-hole, fourth hole, circular protrusions axle sleeve, circular groove axle sleeve and fifth hole are by forging round steel or forging molding of square steel.
The diameter of preferred described circular groove axle sleeve is less than the circular protrusions axle sleeve.
The diameter of preferred described the first through hole, the second through hole, third through-hole and fourth hole is less than the diameter of fifth hole.
Preferred described differential mechanism body has at least both sides to be set to spill and symmetry.
Compared with prior art, the beneficial effects of the utility model are:
Improved automotive of the present utility model has the following advantages with the differential mechanism flange: 1, one-body molded when producing differential mechanism flange blank, saved follow-up secondary fine procedure, and improved manufacturing efficiency and assembled simpler; 2, the differential mechanism flange blank of producing is set to concave panel, has saved the production material, has guaranteed working life, has improved use safety coefficient and operation working efficiency; While the utility model cost of production is low, easy popularization.
