Problems solved by technology

[0004] However, since the locking mechanism is installed in the differential housing, during the rotation of the differential, the locking mechanism rotates together with the differential, consuming part of the energy, thus making the power transmission efficiency of the car's transmission system low

Embodiment 1

[0039] see figure 1 , the embodiment of the present invention provides a limited-slip differential, which is arranged in the cavity of the transmission housing 1, including: a differential housing 2, a planetary shaft 3 and a locking mechanism 5, wherein the differential housing The body 2 has a housing cavity, the planetary shaft 3 is set in the housing cavity and the two ends of the planetary shaft 3 protrude from the differential case 2 respectively, and the locking mechanism 5 is set in the guide groove on the transmission case 1 , the locking mechanism 5 includes a driving device and a locking member 56, the locking member 56 is connected to the driving device, and the axis of the locking member 56 is perpendicular to the axis of the planetary shaft 3, when the planetary shaft 3 protrudes from the differential case 2 At least one locking groove 6 is respectively arranged at both ends, and each locking groove 6 is respectively arranged corresponding to the locking member 5...

Embodiment 2

[0050] like figure 1 As shown, Embodiment 2 of the present invention provides a transmission, including: a transmission housing 1 with a cavity, a guide groove 6 is provided in the transmission housing 1, and a slip-limiting mechanism as described in the first embodiment is provided in the cavity. For the differential, the locking mechanism of the limited slip differential is arranged in the guide groove 6, and the locking mechanism can protrude from the guide groove 6.

[0051] When the car is running on a normal road, the locking mechanism 5 is located in the guide groove of the transmission, and the limited-slip differential operates normally. The locking piece 56 protrudes from the guide groove and extends into the locking groove 6 of the planetary shaft 3, so that the locking groove 6 stops rotating around the axis of the planetary shaft 3. Therefore, the locking mechanism 5 makes the planetary shaft 3 Autorotation is stopped, which locks the limited slip differential. ...

Embodiment 3

[0053] Embodiment 3 of the present invention provides an automobile, and the transmission provided in Embodiment 2 above is arranged in the automobile.

[0054] The locking mechanism of the limited-slip differential in the transmission is set in the guide groove of the transmission housing. When the car encounters a special road surface and makes one wheel slip, the locking mechanism can lock the limited-slip differential. The working process of the locking mechanism in the third embodiment is the same as the working process of the locking mechanism in the first embodiment above, and will not be repeated here. Compared with the prior art, the locking mechanism of the limited-slip differential in the automobile provided by the present invention is arranged in the guide groove of the transmission housing, and will not rotate together with the limited-slip differential, thereby reducing energy loss , and then improve the transmission efficiency of the car's transmission system. ...

Abstract

The invention provides a limited slip differential, a transmission and a vehicle, and relates to the technical field of differentials. The limited slip differential, the transmission and the vehicle aim to solve the problem that the power transmission efficiency of a transmission system of a vehicle is low. The limited slip differential comprises a differential shell arranged inside a cavity of a transmission shell; a containing cavity is arranged inside the differential shell; a planet shaft is arranged inside the containing cavity; and the two ends of the planet shaft extend out of the differential shell. The limited slip differential further comprises a locking mechanism arranged in a guide groove in the transmission shell; the locking mechanism comprises a drive device and an annular locking piece connected with the drive device; the axis of the locking piece is perpendicular with the axis of the planet shaft; two areas corresponding to the planet shaft and the locking piece are each provided with at least one locking groove; and during use, the locking piece extends into the locking groove under driving of the drive device, so that the planet shaft stops rotating. The limited slip differential is applied in the vehicle.

Description

technical field [0001] The invention relates to the technical field of differentials, in particular to a limited-slip differential, a transmission and an automobile. Background technique [0002] The differential is installed between the driving wheels on the left and right sides of the car. When the car is turning or driving on uneven roads, the differential can ensure that the driving wheels on the left and right sides have different speeds when the strokes are not equal. However, the existence of the differential prevents the power from being effectively transmitted when the driving wheel on one side of the car slips, so a limited-slip differential appears. The limited-slip differential locks the differential when one side of the car slips, so that The driving wheels on the left and right sides can get the same power, so that the problem of uneven power transmission that occurs when the wheel on one side of the car slips can be better solved. [0003] At present, there i...
