Problems solved by technology

[0004] The invention provides a meshing automobile differential that can make the two half-shafts rotate synchronously when the differential speed of the two half-shafts is greater than the set value, which solves the problem of the existing differential when the car is running on a bad road. Problems that seriously affect the ability to pass

Abstract

The invention relates to an automobile differential mechanism. The meshing type automobile differential mechanism comprises a planet carrier, half shaft gears, planet gears and a driven gear. The planet gears are connected with the planet carrier together through a planet wheel shaft. The planet carrier is connected with a fixed connecting plate. The fixed connecting plate is provided with first connecting teeth. The half shaft gears is penetrated by a push rod. The push rod is connected with a driven drive block and a movable connecting plate. The movable connecting plate is provided with second connecting teeth. The planet wheel shaft is provided with a sliding rod. The sliding rod is connected with a driving drive block in a sliding manner. The fixed connecting plate and the movable connecting plate are located outside the area defined by the two half shaft gears and the planet gears. The driving drive block and the driven drive block are located inside the area defined by the two half shaft gears and the planet gears. The automobile differential mechanism has the beneficial effect that when the differential speed of two half shafts is larger than the set value, the two half shafts can synchronously rotate, and solves 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.

Description

technical field [0001] The invention relates to an automobile differential, in particular to an engaging 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 needs to b...
