Oil-pressure type slide-limiting differential gear

Abstract

The invention provides an oil-pressure type slide-limiting differential gear which mainly adopts the structure that a disk surface and a plurality of transmission areas arranged at intervals are arranged on each side of a bearing disk is adopted to form an action area; the transmission areas on two sides are matched with each other, so that transmission gears of gear sets on two sides are meshed with each other; at least one sealing and blocking piece is arranged on a shaft rod of each transmission gear in a surrounding manner; a flow limiting hole capable of accommodating a flow limiting piece is formed in each jointing disk on two sides of the bearing disk; the flow limiting holes correspond to gaps between the meshed transmission gears on the two sides. Due to the sealing and blocking of the sealing and blocking piece, the transmission areas are sealed, so as to be in high-pressure states; flowing to the low-pressure environment formed outside the jointing disks, oil can enter the gaps between the meshed transmission gears through the flow limiting holes under the matching of the flow limiting pieces, so as to achieve oil circulatory backflow, and promote speed difference and slide limiting effects.

Description

technical field [0001] The invention relates to the field of a limited-slip differential structure, in particular to an oil hydraulic limited-slip differential. Background technique [0002] The differential is a device set up to cope with the different rotation speeds of the wheels on both sides when the vehicle is turning. The traditional differential is a simple mechanical structure, mainly by means of two planetary helical gears meshing with the side gears of the axles on both sides to facilitate turning. When the two wheels rotate at different speeds on different ground environments; however, the structure of the conventional differential is passively matched and cannot limit the rotation of the wheel shaft; One gripping wheel also loses driving force at the same time. For this reason, the device of limited slip differential came out later. Its function is to prevent the other gripping wheel from losing power when the wheel slips; however, limited slip differential The...

[0002] The differential is a device set up to cope with the different rotation speeds of the wheels on both sides when the vehicle is turning. The traditional differential is a simple mechanical structure, mainly by means of two planetary helical gears meshing with the side gears of the axles on both sides to facilitate turning. When the two wheels rotate at different speeds on different ground environments; however, the structure of the conventional differential is passively matched and cannot limit the rotation of the wheel shaft; One gripping wheel also loses driving force at the same time. For this reason, the device of limited slip differential came out later. Its function is to prevent the other gripping wheel from losing power when the wheel slips; however, limited slip differential There are many types and structures of gears, including mechanical clutches, combinations of helical planetary gears, or multi-plate clutches. However, the aforementioned limited-slip differentials need to be matched with oil when they are actually used. Only when it is used, the differential speed and limited slip effect can be normally exerted. However, the current limited slip differential often has oil leakage, that is, although the oil can be diverted to the differential gear, it is often easy to have oil leakage. Leakage problem, so that the amount of oil between the gears is insufficient, which relatively reduces the differential speed and the limited slip effect, which needs to be improved
