Abstract
The invention discloses a high-stability differential transmission system. The high-stability differential transmission system comprises an input part, a differential mechanism, two half-axle gears and two output shafts, wherein the two half-axle gears and the two output shafts are in one-to-one correspondence and coaxially fixed on the differential mechanism, the input part is in meshing transmission with the differential body of the differential mechanism through a bevel gear pair, and a limit seat for radially limiting the drive gear of the bevel gear pair is disposed on the shell of the differential mechanism. The high-stability differential transmission system has the advantages that the structural stability of the drive bevel gear in the bevel gear pair and the corresponding axle can be increased, differential mechanism operation is benefited, and service life is prolonged.
Description
Technical field
The present invention relates to a kind of mechanical device, particularly relate to a kind of high stability differential transmission systems.
Background technique
Differential mechanism is usually used in vehicle, a left side can be made, right driving wheel realizes rotating with different rotating speeds, primarily of left and right differential gear, two planetary pinions, shell, planet wheel shaft and forming as the differential body of planet carrier, when automobile turning traveling or when travelling on uneven road surface, left and right wheels is rolled with different rotating speeds, namely ensure that both sides drive wheel to make PURE ROLLING, when four-wheel drive, also need to add center differential in order to adjust the speed discrepancy of front and back wheels, in prior art, the input shaft of differential mechanism is subject to the reaction force of tangent direction, stability extreme difference, be unfavorable for the running of box of tricks, affect working life.
Summary of the invention
In view of this, the object of this invention is to provide a kind of high stability differential transmission systems, improve stability, be beneficial to the running of box of tricks, increase the service life.
High stability differential transmission systems of the present invention, comprise input part, box of tricks and be coaxially fixed on two output shafts of two differential gears of box of tricks one to one, by a bevel gear pair engagement driving between the differential body of described input part and box of tricks; The shell of described box of tricks is provided with for carrying out radial spacing position limit socket to the driving gear of bevel gear pair; Described position limit socket comprises supporting base, limited post and Limit Bearing; The shell of described supporting base and box of tricks is wholely set; The driving gear of described limited post and bevel gear pair coaxially arranges and is fixed on supporting base, and limited post axially stretches into the inside of the driving gear of bevel gear pair, and described Limit Bearing is placed on limited post and is connected between limited post and the driving gear of bevel gear pair;
Further, described input part comprises input shaft and is fixed on the drive bevel gear of input shaft; The differential body of box of tricks is fixed with for taking turns the driven wheel of differential of engagement driving with drive bevel gear;
Further, described input shaft single-degree-of-freedom is rotationally connected with the shell of box of tricks.
The invention has the beneficial effects as follows: high stability differential transmission systems of the present invention, the structure stability of drive bevel gear in bevel gear pair and corresponding wheel shaft can be improved, be beneficial to the running of box of tricks, increase the service life.
