Transmission device with differential function

Abstract

The invention relates a transmission device with a differential function, which is used for driving two wheel shafts. The transmission device comprises a shaft sleeve which can be driven by a power source to rotate around an axial line and two unidirectional ratchets which are fixedly arranged at both sides of the shaft sleeve and are respectively fixedly connected with the wheel shafts to form linkage. With the rotation of the shaft sleeve, the unidirectional ratchets can drive the wheel shafts to synchronously rotate in the forward direction, and can permit one of the wheel shafts to idle in the forward direction in an asynchronous condition. Thus, based on the special design of the unidirectional ratchets, the invention enables the wheel shafts rotating in the same direction to rotate at different rotation speeds, thereby maintaining the steering stability.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device with a differential function for driving two wheel sets and generating a speed difference. Background technique [0002] see figure 1 Taking the transmission device 1 of a general vehicle (not shown) as an example, it mainly includes a wheel shaft 11, two wheels 12 that are arranged at two ends of the wheel shaft 11 and rotate coaxially with the wheel shaft 11, and are coaxial with the wheel shaft 11. A passive member 13 that the shaft rotates and is used to transmit power. Thereby, when the driven member 13 is driven by a power source to drive the wheel shaft 11 to rotate, the aforementioned wheels 12 and the wheel shaft 11 can be rotated synchronously to achieve the purpose of driving the vehicle. [0003] However, when the vehicle is turning, the path taken by the inner wheel 12 is shorter and the path taken by the outer wheel 12 is longer, so that the left and ...

Problems solved by technology

However, the differentials currently used on the market mainly use bevel gear sets as the differential structure, which not only has complex structures and components, but also has defects such as difficult assembly and maintenance, large power loss, and high cost.

[0005] This shows that above-mentioned existing general vehicle transmission device obviously still has inconvenience and defect in structure and use, and demands urgently further improving

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
