Technical field
The utility model is the design of relevant a kind of telecar center differential gear wheel lightweight structure, can make external power gear wheel improve itself weight as the telecar center differential, make light-weighted result must have more the powerful property of horsepower output, kinetic energy loss is reduced relatively, promote the power performance effect of car body.
Background technology
Telecar definitely is a kind of toy that liked by adult and child, is because of it can become a kind of action toy thing of following one's bent and controlling, and it whole simple and easyly control, can run quickly at a high speed, becomes the challenging amusement appliance of dark tool.And the bigger telecar of general horsepower output, center differential is a considerable structure in the telecar, center differential structure (please join shown in Figure 1) commonly used, mainly in a housing A, be equipped with four scroll gear C, on each scroll gear C, be provided with helical gear C1 down again, between scroll gear C, install the two axis body B that the end is provided with scroll gear B1 equally, and make adjacent scroll gear and last, following helical gear is meshing with each other, when making turn through scroll gear C and the mutual meshing transmission of helical gear C1, can produce tangible differential between two axis body B and make, to suppress skidding.And generally being all steel, makes the gear wheel D that is locked in differential mechanism one end, to be suitable for next wear-resisting characteristic of its high-speed friction, but its weight of steel metal is heavier, thereby power loss will produce virtually, thereby how a kind of light-weighted its main target that is is provided.
The inventor is because above-mentioned conventional central differential mechanism commonly used structure remains improved shortcoming, phase can provide a kind of effectively with the light-weighted design of center differential gear wheel weight, make identical engine horsepower output down, after each time throttle is opened, can be more promptly with transmission of power to power transmission shaft, see through the earth-grasping force of tire again and go out car body, reduce the phenomenon of power sluggishness, be think of, the design team's system of grinding with great concentration, consumption is popular to be used to provide, and desires to grind the invention motivation of wound for the utility model.
Summary of the invention
Main purpose of the present utility model effectively alleviates in the gear wheel weight that provides a kind of mat with center differential, has wearability simultaneously equally, exports benefit to obtain preferable power, and can be the effect that reduces oil consumption.
Secondary objective of the present utility model is providing a kind of manufacturing simple, and the gear wheel structure of the telecar center differential of ease of assembly can make the easier performance function of action of quickening and quickening.
For reaching above-mentioned purpose, the telecar center differential gear wheel lightweight structure that the utility model is designed, main center differential gear wheel with single component is made as at least and is combined into by two members, wherein a member is a gear ring, gear ring is made by the steel metal powder metallurgy, outer rim system in gear ring is provided with tooth, in the inner edge of ring body the joint portion is set; Another member is a disk cover, and disk cover is made by aluminum metal, is provided with the joint portion in the outer rim system of disk cover, and plate body is provided with the hole in the side of disk cover; Make its joint portion of using both as the structure that mutually combines, can utilize the flintiness of steel to come meshing other gear to pass connect required as power to this, reach an anti abrasive effect, and the light weight characteristic of utilizing aluminium matter is made disk body, be incorporated into the central authorities of gear ring, which is provided with on the housing that the hole can be bolted in center differential, reach the light-weighted purpose of gear wheel with this.
During combination, the joint portion of gear ring with its inner rim combined with the joint portion of disk cover outer rim, make unlikely generation sliding phenomenon between the two, and be fixed into a gear wheel.
Other characteristics of the present utility model and specific embodiment can further be understood in the detailed description of following conjunction with figs..

The specific embodiment
As shown in Figure 1, be the outside drawing of the common center differential of a tradition, the preceding clear construction features of describing gear wheel are in this no longer superfluous stating.
As Fig. 2, shown in Figure 3, the utility model is formed so its structure setting has by a gear ring 10 and a disk cover 20 for gear wheel is made lightweight; Shown adopts the metal powder metallurgy of steel to be processed in gear ring 10, establishes most teeth 11 in outer rim system and makes it to arrange in the form of a ring, establishes the joint portion in the inner edge of gear ring 10 in addition, and its joint portion is made as internal screw thread 12 among this graphic embodiment.
One disk cover 20 is provided with the joint portion in the same system of the outer rim of lid, and its joint portion is made as external screw teeth 21 among this graphic embodiment, and plate body is provided with hole 22 in the side of disk cover;
During combination, gear ring 10 is screwed with the internal screw thread 12 of its inner rim joint portion external screw teeth 21 with disk cover 20 outer rim joint portions, makes both unlikely each other generation sliding phenomenons that strikes up partnership, and be fixed into a gear wheel.
Please join Fig. 4, Fig. 5, can make on therefore the utility model is produced and establish an assembled fixture template 30, system is established the depression of identical gear ring 10 outlines in the plate body of this template, its gear ring 10 is filled in its depression, again disk cover 20 is from top to bottom penetrated hole 22 with spanner 40 its two reference columns 41 and be fixed on the gear ring 10, make its internal screw thread 11 and external screw teeth 21 screw togather one respectively jointly, to become a complete gear wheel.And set thread rotation to, the preferably adopts the direction setting of reverse acting spiral (being anti-tooth) for cooperating engine force-output shaft direction of rotation, makes that its inside and outside thread is unlikely automatically under the powerful rotation of engine torque to get loose.
Please join Fig. 6, Fig. 7, the joint portion of its gear ring 10 is an internal screw thread 11 for establishing in the last specific embodiment, and the joint portion of disk cover 20 is an external screw teeth 21 for establishing, right identical technological thought also can change its internal screw thread 11 changes with an inclined-plane 13 systems to be established, collocation property also changes external screw teeth 21 to change with an inclined-plane 23 systems this moment and establishes simultaneously, both also can finish a firm syntagmatic of two members equally with the awl contract combination interference capability tolerance fit embedding mutually of inclined-plane (13,23) central authorities with it during combination.The mode of perhaps adopting with riveted is provided with, and it belongs to the definition of next joint portion of this case design concept equally.
Therefore when its gear wheel of central differential mechanism is driven to rotate, disk cover 20 light weights because of its aluminium matter system, then reduce the weight of its gear greatly, can be driven rotation at a high speed fast, increase the validity that engine is exerted oneself, for telecar pay attention to that performance is exerted oneself and the function quickening, quicken again for, the splendid improvement design of can yet be regarded as.
In sum, according to the content that is above disclosed, the utility model can reach the intended purposes of utility model really, and a kind of telecar center differential gear wheel lightweight structure is provided, and has practical value.
