Hybrid power type planetary gear slope slipping-preventing mechanism

Abstract

The invention discloses a hybrid power type planetary gear slope slipping-preventing mechanism. The hybrid power type planetary gear slope slipping-preventing mechanism comprises a machine frame, a planetary speed change mechanism, a power input piece, a power output piece, a first clutch, a second clutch and a motor; combination of a sun wheel, a planet carrier and a tooth ring in the planetary speed change mechanism according to any sequence is corresponding to a power input end, a power output end and an intermediate transmission part; the motor inputs power to the power input piece; the power input piece cooperates with the power input end through the first clutch to realize power transmission; the power input piece cooperates with the power output piece through the second clutch to realize power transmission; the power output piece cooperates with the power output end in a transmission way; and hybrid power driving of a vehicle can be realized, the slope slipping-preventing mechanism is integrated into a speed reducer, the slope slipping-preventing function is realized through self-locking of the speed reducer, a related brake system does not need to be increased, and the structure of the slope slipping-preventing is simplified.

Description

technical field [0001] The invention relates to the field of vehicle engineering, and relates to a hybrid planetary gear anti-slope mechanism. Background technique [0002] When a motor vehicle is parked or started on an uphill section, a downward force parallel to the slope is generated due to the vehicle's own weight, that is, the slope resistance, which will cause the vehicle to slide backward along the slope, which is extremely unsafe. For a manual transmission motor vehicle, the driver must coordinate and cooperate with the parking brake, clutch and accelerator pedal when going uphill, but this series of operations is very cumbersome and difficult to master. It cannot be realized, and this inherent problem has become a major defect of MT vehicles. At the same time, due to the inherent characteristics of AMT vehicles, it is difficult to control the ramp start of AMT vehicles. This major defect of AMT vehicles hinders the popularization and use of AMT vehicles. For vehic...

Problems solved by technology

[0003] At present, the braking system with uphill assist function is usually used in vehicles to cooperate with braking and other operations to prevent the vehicle from sliding down; but when the above braking system with uphill assist function is realized, it needs to be added Related braking system, which will increase the complexity of the braking system and increase the cost of the whole vehicle;

[0004] At present, vehicles also use a power system composed of motors, motor controllers and related sensors to prevent vehicle slopes; Control the vehicle to enter the anti-slope mode; therefore, there is a certain delay in judgment in the above implementation method, the performance is unreliable, and there is a safety risk;
