Problems solved by technology

[0002] At present, sports equipment with two-wheel drive and steering, similar to wheelchairs, generally use dual power to drive the two runners respectively, and realize it by controlling the speed of the two runners. Front and rear movement and steering, but based on the open-loop control characteristics of the dual power system, the two runners cannot achieve constant speed rotation or precise steering, often appear serpentine forward and unstable turning radius steering, and the movement of wheelchair equipment poor control

Abstract

The invention relates to a star-axis difference adjusting differential mechanism. The two output freedom degrees of the differential mechanism are input to two planetary gear sets which are mutually locked by virtue of a planetary gear shaft, the rotative speed difference of the two output freedom degrees is adjusted by controlling the two planetary gear sets, a constant speed driving shaft and aworm (1) of the difference adjusting differential mechanism directly drive a constant speed driving worm wheel (2), and the constant speed worm wheel (2) and a differential mechanism gear carrier (3)are a whole; a differential mechanism planetary gear (4), a right axle shaft bevel gear (5) and a left axle shaft bevel gear (6) are arranged in the differential mechanism gear carrier (3), so as to form the differential mechanism. The invention can effectively control the speed difference of two rotating wheels, can realize absolutely constant speed and accurate and controllable rotative speed difference and further can realize stable linear motion and accurate steering, thus being especially applicable to driving on the rotating wheel of wheel chair.

Description

technical field [0001] The invention belongs to the technical field of differentials for vehicles, and in particular relates to a differential differential, which can effectively control the speed difference between two running wheels, and can realize a completely constant speed and a precise and controllable speed difference, and then realize a smooth straight line Sporty and precise steering, especially for the drive of wheelchair-type wheels. Background technique [0002] At present, sports equipment with dual-wheel drive and steering, similar to wheelchairs, generally use dual power to drive the two runners respectively, and realize forward and backward movement and steering by controlling the speed of the two runners, but based on the open-loop control characteristics of the dual-power system , the two runners cannot well realize constant speed rotation or precise steering, and there are often serpentine advances and unstable turning radius steering, and the motion cont...
