Abstract
The invention discloses a double-end-face gear transmission mechanism which comprises an input part, a differential mechanism and two output shafts of two half axle gears corresponding to each other and coaxially fixed to the differential mechanism. The input part and a differential body of the differential mechanism are in transmission connection through two bevel gears in parallel symmetrically and a double-end-face bevel gear meshed with the two bevel gears. By the adoption of the double-end-face gear transmission mechanism, the input part of the transmission mechanism and the differential body of the differential mechanism are in transmission connection through the two bevel gears in parallel symmetrically and the double-end-face bevel gear meshed with the two bevel gears, the axial component force generated by the double-end-face bevel gear is counteracted through the two bevel gears, it can be guaranteed that the differential body is balanced in axial stress, operation of the differential mechanism is facilitated, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of mechanical device, particularly relate to a kind of Double End gear drive.
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, generally be in transmission connection by a bevel gear pair between the differential body of differential mechanism and input shaft in prior art, and be subject to the impact of the pressure angle of gear pair, the follower of bevel gear pair can be subject to end thrust, and this power is passed to differential body, cause differential body axially loaded uneven, 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 Double End gear drive, the differential body axially loaded balance of its box of tricks can be ensured, be beneficial to the running of box of tricks, increase the service life.
Double End gear drive 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, be connected by two of Parallel Symmetric bevel gears with the Double End bevel gear drive that this two bevel gear engages between described input part and the differential body of box of tricks;
Further, described input part comprises input shaft and to be arranged in parallel with input shaft and along the reversing shaft of output shaft axially-aligned; Be in transmission connection by gear pair between described reversing shaft and input shaft and make mutually to rotate backward between reversing shaft and input shaft;
Further, described input shaft is coaxially fixed with the first drive bevel gear; Described reversing shaft is coaxially fixed with the second drive bevel gear; The differential body of box of tricks is fixed with for the Double End bevel gear with the first drive bevel gear and the second drive bevel gear engagement driving;
Further, described input shaft and the equal single-degree-of-freedom of reversing shaft are rotationally connected with the shell of box of tricks.
The invention has the beneficial effects as follows: Double End gear drive of the present invention, be connected by two of Parallel Symmetric bevel gears with the Double End bevel gear drive that this two bevel gear engages between its input part and the differential body of box of tricks, and two bevel gears are cancelled out each other to the axial thrust load that Double End bevel gear produces, can ensure that differential body axially loaded balances, be beneficial to the running of box of tricks, increase the service life.
