Abstract

The invention relates to an automobile differential mechanism. The internal friction type automobile differential mechanism comprises a planet carrier and two half shaft gears arranged at the two ends of the planet carrier. The planet carrier is connected with planet gears and a driven gear driving the planet carrier to rotate. The planet gears are meshed with the half shaft gears together. The planet gears are connected with the planet carrier together through a planet wheel shaft. The planet carrier is connected with a fixed friction plate. Sliding rods are arranged on the peripheral face of the planet wheel shaft. The sliding rods are in sliding connection with a movable friction plate which is matched with the fixed friction plate and slides through centrifugal force generated when the planet wheel shaft rotates. The fixed friction plate and the movable friction plate are located inside the area defined by the two half shaft gears and the planet gears. By means of the internal friction type automobile differential mechanism, when the differential speed of two half shafts is larger than the set value, the two half shafts can synchronously rotate; and the problem that according to an existing differential mechanism, when an automobile is driven on a poor road, the passing capability can be seriously affected is solved.

Description

technical field [0001] The invention relates to an automobile differential, in particular to a built-in friction type automobile differential. Background technique [0002] A differential is a differential mechanism that transmits rotational motion from one shaft to two shafts and enables the latter to rotate at different speeds relative to each other. In the Chinese patent application number 2011800533570, the publication date is August 21, 2013, and the patent document titled "Electrically Triggered Locking Differential" discloses an automobile differential with an existing structure. The gear includes a planet carrier and two side gears located in the carrier. When in use, the left and right axle shafts of the car (the front and rear axles when it is an intermediate differential) pass through the axle shaft mounting holes and extend into the planetary wheel frame, and then connect with the two axle gears one by one. gear driven to rotate. During use, lubricating oil ne...
