High-stability adjustable dual-conical-tooth differential gear

Abstract

The invention discloses a high-stability adjustable dual-conical-tooth differential gear. The high-stability adjustable dual-conical-tooth differential gear comprises an input part, a differential mechanism and two output shafts which are coaxially fixed to two axle shaft gears of the differential mechanism in a one-to-one corresponding mode; the input part is in meshed transmission with a differential body of the differential mechanism through two bevel gear pairs in mirror symmetry, and a limiting base for limiting driving wheels of the two bevel gear pairs in the radial direction is arranged on an outer shell of the differential mechanism. According to the high-stability adjustable dual-conical-tooth differential gear, as the input part is in meshed transmission with the differential body of the differential mechanism through the two bevel gear pairs in mirror symmetry, and the axial component force can be offset through driven wheels of the two bevel gear pairs, the axial stress balance of the differential body can be guaranteed, the structure stability of the driving wheels and corresponding wheel shafts is improved, running of the differential mechanism is facilitated, and the service life is prolonged.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a high-stability adjustable double bevel gear differential device. Background technique [0002] Differentials are often used in vehicles to enable the left and right drive wheels to rotate at different speeds. They are mainly composed of left and right side shaft gears, two planetary gears, casings, planetary wheel shafts and a differential body as a planetary carrier. When the car turns When driving or driving on uneven roads, make the left and right wheels roll at different speeds, that is, ensure the pure rolling motion of the driving wheels on both sides. In the prior art, the differential body of the differential and the input shaft are generally connected through a bevel gear pair, and affected by the pressure angle of the gear pair, the driven wheel of the bevel gear pair will receive axial thrust and transfer the force It is transmitted to the differential body, resulting in an un...

[0002] Differentials are often used in vehicles to enable the left and right drive wheels to rotate at different speeds. They are mainly composed of left and right side shaft gears, two planetary gears, casings, planetary wheel shafts and a differential body as a planetary carrier. When the car turns When driving or driving on uneven roads, make the left and right wheels roll at different speeds, that is, ensure the pure rolling motion of the driving wheels on both sides. In the prior art, the differential body of the differential and the input shaft are generally connected through a bevel gear pair, and affected by the pressure angle of the gear pair, the driven wheel of the bevel gear pair will receive axial thrust and transfer the force It is transmitted to the differential body, resulting in an unbalanced axial force on the differential body, and at the same time, the input shaft of the differential device is subjected to a tangential reaction force, resulting in extremely poor stability, which is not conducive to the operation of the differential mechanism and affects the service life; the existing In the technology, agricultural vehicles cannot adjust the distance between the left and right wheels according to the ridge width of the field, so when the ridge width of the field is not standardized, it is not conducive to the vehicle to drive in the field
