Embodiment Construction

[0031]The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0032] Such as figure 1 As shown, a mechanical dual-override adaptive automatic transmission adopting multiple rows of floating overrunning clutches includes a power input mechanism, a high-speed gear transmission mechanism, a low-speed gear transmission mechanism and a main shaft 1 for outputting power.

[0033] See figure 1 and Figure 6 The power input mechanism includes a synchronously rotating motor input flange 8, an input shaft transmission sleeve 9 and an input tooth support flange 10, and the first overrunning clutch 4 can be synchronously rotated and arranged on the input shaft transmission sleeve 9 and Between the input tooth support flanges 10, the input tooth support flange 10 is used to transmit power to the countershaft transmission assembly.

[0034] Specifically, the motor input flange 8 is fixedly sleeved on the motor shaft, so that the mo...

Abstract

The invention discloses a mechanical dual-override adaptive automatic transmission adopting multiple rows of floating overrunning clutches, comprising a power input mechanism, a high-speed gear transmission mechanism, a low-speed gear transmission mechanism and a main shaft for outputting power. With the above technical solution, the second overrunning clutch breaks through the load limit of the traditional overrunning clutch. The length of the inner wheel and rolling elements is short, the force is uniform, the reliability is high during use, and it is difficult for the rolling elements to break. A heavy-duty overrunning clutch capable of extremely high reliability and capable of withstanding super-large loads is manufactured at a lower production cost. Through the improvement of the second overrunning clutch, the self-adaptive automatic transmission device can bear super large load, the reliability is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical transmissions, in particular to a mechanical dual-override self-adaptive automatic transmission using multiple rows of floating overrunning clutches. Background technique [0002] Due to the limitations of its transmission structure, the existing electric vehicles are completely controlled by the driver based on experience when the driving resistance cannot be accurately known during driving. The actual driving conditions do not match, causing the motor to stall. Especially when the vehicle is under low-speed and heavy-load conditions such as starting, climbing, and headwind, the motor often needs to work at low efficiency, low speed, and high torque, which is likely to cause accidental damage to the motor and increase maintenance and replacement costs. It directly affects the cruising range of the battery. For models with high economic requirements such as electric logistics vehicles, the tr...
