Problems solved by technology
by figure 1 and figure 2 Taking the structure of the known model car shown as an example, the enlarged diameter portion 5a of the output shaft 5 obviously protrudes outside the seat 8, and the bottom end of the connecting hole 5b cannot extend to the small diameter portion 5c, so that the ball head 7a of the transmission shaft 7 At most, it can only move to a position close to but not exceeding the bearing 3. In other words, when the drive shaft 7 moves up and down with the wheels 9, it will swing with a larger swing angle. This situation is not only unfavorable for the chassis of the model car Being close to the ground will also affect the grip of the wheels 9, and the instability it will cause to the body will affect the speed and racing results
[0004] In addition, the outer diameter of the enlarged diameter portion 5a of the output shaft 5 is larger than the inner diameter of the bearing 3, so that when the bearing 3 is to be replaced, the entire differential must be disassembled before the replacement operation can be performed.

The invention relates to a stabilizing structure used for a model car. The stabilizing structure comprises a differential mechanism and two transmission shafts which are installed between two car wheels, wherein the differential mechanism comprises a shell body, a pair of bearings and a pair of output shafts; the two bearings are arranged on two outer sides of the shell body; the two output shafts penetrate the shell body and the bearings; each output shaft comprises a connecting holes, and the bottom ends of the connecting holes extend to pass through the corresponding bearings; one end of each transmission shaft is connected with the corresponding car wheel, and the other end of each transmission shaft is movably connected with the connecting hole of the corresponding output shaft; therefore, a distance between two ends of each transmission shaft is lengthened, which is beneficial to reduce swinging angles so as to stabilize a car body and increase the speed of a car.
Description
technical field [0001] The present invention is related to model cars, and more specifically refers to a stable structure for model cars. Background technique [0002] figure 1 Shown is a sectional view of a differential for a general model car, revealing that it includes an outer cover 1 fixed to one end of a main gear 2, and the outer cover 1 and the main gear 2 respectively have a neck section 1a, 2a extending outward, each neck section 1a , 2a are respectively sleeved with a bearing 3, a planetary gear set 4 is accommodated inside the outer cover 1, and a pair of output shafts 5 pass through the outer cover 1 and the main gear 2 respectively. Wherein, one end of the output shaft 5 located inside the housing 1 is connected with a sun gear 6 meshing with the planetary gear set 4, and the other end of the output shaft 5 is an enlarged diameter portion 5a, and a connection hole 5b extends from the end surface of the enlarged diameter portion 5a along the axis. Concavely fo...
