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

Embodiment Construction

[0007] Referring to the accompanying drawings, the present invention is characterized in that the planetary shaft differential differential is to input the two output degrees of freedom of the differential to two sets of mutually locked planetary gear sets through the planetary gear carrier, and then control the two planetary gears The group realizes the adjustment of the rotational speed difference between the two outputs, and uses the constant speed drive shaft and the worm 1 to directly drive the constant speed drive worm gear 2. The constant speed drive worm gear 2 and the differential gear frame 3 are integrated; the differential planetary gear 4, The right half shaft bevel gear 5 and the left half shaft bevel gear 6 are installed in the differential gear frame 3 to form a differential; the left half shaft bevel gear 6 and the left half shaft first transmission gear 8 and the planets carried by the left half shaft The gear bracket 16 is coaxial, the first transmission gear...

Abstract

The invention relates to a planetary shaft difference adjusting differential mechanism. The differential mechanism is characterized in that: two output free degrees of the differential mechanism are input to two groups of planetary gear sets through a planetary gear frame, wherein the two groups of planetary gear sets are interlocked; the rotation speed difference between the two output free degrees is adjusted by controlling the two planetary gear sets; a constant-speed driving worm wheel (2) is directly driven by using a constant-speed driving shaft and a worm (1), wherein the constant-speed driving worm wheel (2) is integrated with a differential mechanism gear frame (3); and the differential mechanism is formed by arranging a differential mechanism planetary gear (4), a right half shaft bevel gear (5) and a left half shaft bevel gear (6) in the differential mechanism gear frame (3). Through the skillfully designed difference adjusting differential mechanism, the speed difference between two rotating wheels can be effectively controlled, complete constant-speed and precisely controllable rotation speed difference can be realized and then stable rectilinear motion and accurate steering can be realized.

Description

technical field [0001] The invention belongs to the technical field of differentials for vehicles, and in particular relates to a planetary shaft 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 stable The linear motion and precise steering are especially applied to the drive of wheelchair 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, a...
