Planetary gear type anti-slope-slipping mechanism with releasing function

Abstract

The invention discloses a planetary gear type anti-slope-slipping mechanism with a releasing function. The planetary gear type anti-slope-slipping mechanism comprises a rack, a planetary speed changemechanism, a power input piece, a power output piece, a first clutch, a second clutch and a third clutch. Any sequence combination of a sun gear, a planet carrier and a gear ring in the planet speed change mechanism corresponds to a power input end, a power output end and a middle transmission part respectively, the power input piece is matched with the power input end through the first clutch toachieve the power transmission, the power input piece is matched with the power output end through the second clutch to achieve the power transmission, and the middle transmission part is matched withthe rack through the third clutch. The anti-slope-slipping mechanism is integrated in the planet speed change mechanism, the anti-slope-slipping function is achieved through the locking of the planetspeed change mechanism, a related braking system does not need to be additionally arranged, and the structure of the anti-slope-slipping mechanism is simplified.

Description

technical field [0001] The invention relates to the field of vehicle engineering, and relates to a planetary gear type anti-slope mechanism with a release function. 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 AM...

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;
