Vehicle as well as axle and differential mechanism thereof

Abstract

The invention discloses a vehicle as well as an axle thereof and a differential mechanism. The differential mechanism comprises a driven disc, two semi-shaft connectors and two groups of connection devices, wherein the inner circumferential surface of the driven disc is a first contact surface; the outer peripheral surfaces of the semi-shaft connectors are second contact surfaces; one second contact surface is a ring surface, and the other second contact surface is a polygonal surface; each group of the connection devices comprises a rolling part, a rolling retainer, a switching driving part, a switching driven part and a first elastic resetting mechanism; the rolling part and the ring surface have a separation position and a connection position; the switching driving part selectively drives the switching driven part to move; the first elastic resetting mechanism moves from the separation position to the connection position and is used for enabling the rolling part to return to the separation position from the connection position. Therefore, the differential mechanism can control the switching from a two-drive mode to a four-drive mode and control the switching from the four-drive mode to the two-drive mode; the connection devices can be switched flexibly; and the switching stability is good.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and its axle and differential. Background technique [0002] In the related art, the vehicle axle generally adopts a planetary differential structure, but the planetary differential structure has the following problems: the input power cannot be cut off, and a transfer case must be added when transfer is required. There is also a possibility of top teeth or seizure when opening, resulting in poor transfer effect; and when the sliding force is lost on one side, the other side has no power output; to solve the power loss, a differential lock structure is added, which leads to a planetary differential structure. Complicated, the existing Fangrong differential lock mechanism has a probability of abutting teeth or seizing when it is combined and disengaged, and the differential locking effect is poor. Based on this, a vehicle with the above-mentioned planetary differential...

[0002] In the related art, the vehicle axle generally adopts a planetary differential structure, but the planetary differential structure has the following problems: the input power cannot be cut off, and a transfer case must be added when transfer is required. There is also a possibility of top teeth or seizure when opening, resulting in poor transfer effect; and when the sliding force is lost on one side, the other side has no power output; to solve the power loss, a differential lock structure is added, which leads to a planetary differential structure. Complicated, the existing Fang Rong differential lock mechanism has a probability of pushing teeth or seizing when it is combined and disengaged, and the differential lock effect is poor

Based on this, a vehicle with the above-mentioned planetary differential structure will result in poor drivability and a poor driving experience for the driver
