Continuous-power-shifting two-gear speed changing box

Abstract

The invention discloses a continuous-power-shifting two-gear speed changing box which comprises a speed changing box body, a power input shaft, a power output shaft, a slow-gear transmission chain and a rapid-gear transmission chain. The rapid-gear transmission chain is of a clutch structure, the slow-gear transmission chain is provided with an overrun clutch, the overrun clutch conducts overrunning when the rapid-gear transmission chain is in joint transmission, the power output shaft is in transmission fit to output power to a differential mechanism, according to the two-gear speed changing box, the output power of a power device is not required to be cut off, the switching between the slow gear and the rapid gear can be directly conducted, the power output of the power device is kept and matched with the running road condition, the jerking sense is reduced, controllability is improved, the driving comfort of a motor vehicle is improved, the power device can stably run for a long period, the service life of the power device is prolonged, and driving energy resources are saved. Further, the joint between the gears is smooth and stable, power consumption in climbing is reduced, power of the power device is fully utilized on the flat ground, driving and gear shifting of the motor vehicle are more stable and smooth, and the aims of saving energy, being environmentally friendly and reducing the use cost are achieved.

Description

technical field [0001] The invention relates to a motor vehicle component, in particular to a two-speed gearbox with continuous power shifting. Background technique [0002] A motor vehicle is a vehicle that is driven or towed by a power plant (including electric and fuel gas vehicles) and travels on the road, generally including a power plant, a transmission, and a wheel frame assembly; the transmission transmits the output power of the power plant to the Wheels are used to drive the vehicle. In the prior art, the main function of the transmission is to change the transmission ratio to meet the traction requirements of different driving conditions, so that the engine or motor can work under favorable working conditions as much as possible. Generally, it is divided into geared and gearless transmissions. [0003] In the prior art, due to its good adaptability to driving road conditions, the geared transmission can be shifted according to different resistances, so that the p...

Problems solved by technology

However, the geared transmission needs to cut off the power during the gear shifting operation, so there will be a sense of frustration during the gear shifting process, which will affect the comfort of driving and riding, and the operation will be complicated, which will affect the handling; even some automatic transmissions are still There are the above problems

Moreover, this structure of cutting off the output power for shifting will make the power output of the power unit unstable, which will affect the operation stability of the power unit and cause a waste of energy for its operation.
