Embodiment 1

[0019] like figure 1 , figure 2 , image 3 and Figure 4 As shown in the figure, a new type of differential includes a casing 1, a lubricating oil is arranged in the casing, a left output half shaft 2 and a right output half shaft 3 are arranged in the casing 1, and the left output half shaft 2 and the right output half shaft are arranged in the casing 1. The shaft 3 is erected inside the casing 1 through the bearing 4, the left output half shaft 2 and the right output half shaft 3 are coaxial, and there is no contact between them, and the left output half shaft 2 and the right output half shaft 3 protrude to the casing 1. The outer shaft is arranged in the axial direction as a middle and empty inner spline slot 5, and the inner spline slot 5 is used for transmission between the axle shaft of the automobile.

Embodiment 2

[0028] Under the condition that other structures in the device are the same, the first left side gear and the second left side gear are both ratchet mechanisms, the rotation directions of the two ratchet mechanisms are opposite, and the first transmission gear is located in the first Between the left side gear and the second left side gear, the left and right sides of the first transmission gear are respectively set as hollow sleeves, the inner circular surface of the sleeve is provided with teeth, and the teeth on the left and right sides of the first transmission gear can be respectively Meshes with the teeth in the ratchet mechanism. The shape and specification of the first right side gear and the first left side gear are exactly the same, the shape and specification of the second right side gear and the second left side gear are exactly the same, and the second transmission gear is located on the first right side. Between the gear and the second right side axle gear, the s...

Abstract

The invention belongs to the field of automobile parts, and particularly relates to a novel differential. The novel differential comprises a machine case; a left output half shaft and a right output half shaft are arranged in the machine case; the outer circle face of the left output half shaft is sequentially sleeved with a first left half shaft gear, a first transmission gear and a second left half shaft gear from left to right; the first left half shaft gear and the second left half shaft gear are fixed to the outer circle face of the left output half shaft; teeth on the first left half shaft gear and the second left half shaft gear are opposite in rotating direction; the left side and the right side of the first transmission gear are provided with teeth engaged with the first left half shaft gear and the second left half shaft gear; the structure of the right output half shaft is the same as that of the left output half shaft; the exteriors of the left output half shaft and the right output half shaft are wrapped by transmission sleeves which can slide in the axis direction of the left output half shaft; the inner walls of the transmission sleeves are connected with the first transmission gear and a second transmission gear correspondingly; and shifting fork rings and driven gear rings are arranged on the outer walls of the transmission sleeves. The device is simplified in structure and low in cost.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a novel differential gear. Background technique [0002] The car differential is the main part of the drive car. Its function is to transmit power to the two half shafts, while allowing the two half shafts to rotate at different speeds, so that the wheels on both sides can run at unequal distances in the form of pure rolling as much as possible, reducing the friction between the tires and the ground. The power of the car engine is transmitted through the clutch, transmission, transmission shaft, and finally to the drive axle and then distributed to the left and right axle drive wheels. On this power transmission path, the drive axle is the last assembly, and its main components are the reducer and The differential is used for deceleration, distance increase and differential function. The differential is generally composed of planetary gears, planetary carrier (differential housing), s...
