Abstract
A Hyperbolic rear axle of a power assisting tricycle relates to an improved rear axle of an electric power assisting tricycle, and comprises a rear axle stand (1), a left half shaft and a right half shaft (2 and 3), a left hub and a right hub (4 and 5), a hand fly wheel (6), an electric fly wheel (7) and ratchet compensating gears (11). The hand fly wheel (6) and the inner sleeve of the electric fly wheel (7) are fixed on a pipe sleeve (12); ring flanges (13) are fixed at two ends of the pipe sleeve (12); the pipe sleeve (12) is placed between a left shaft sleeve and a right shaft sleeve (8 and 9) of the axle stand (1); the ratchet compensating gears (11) is a ratchet mechanism with a spline slot sleeved therein; the outer sleeve of the ratchet compensating gear (11) is fixed on the ring flanges (13) at the two ends of the pipe sleeve (12); and the left half shaft and the right half shaft (2 and 3) are connected with the ratchet compensating gears (11) at the two ends of the pipe sleeve (12) through splines. The hyperbolic rear axle of the power assisting tricycle has the advantages of simple structure and low manufacturing cost, and as driven by double shafts, the hyperbolic rearaxle also has the advantages of energy conservation, side skidding resistance, stable brake, security and reliability.
Description
Technical field
The utility model relates to a kind of tricycle rear axle, is specifically related to the improvement to electric power boosted tricycle back axle.
Background technology
Its back axle of common electric tricycle does not have box of tricks, and mostly is the single shaft driving, has the big shortcoming of power consumption, and travelling is prone to the sideslip phenomenon on ice and snow or muddy road surface, and influences driving safety.Existing tricycle rear axle with box of tricks then generally adopts the gear type box of tricks, has complex structure, the shortcoming that cost is high.
The utility model content
Technical problem to be solved in the utility model is: a kind of simple in structure, boosted tricycle hyperbolic back axle that cost is low is provided.
Technical solution of the present utility model is: it comprises rear axle stand, a left side, right axle shaft, a left side, right wheel hub, the manpower flywheel, electric power flywheel and ratchet diff, a left side, right wheel hub is separately fixed at the left side of rear axle stand, the right axle sleeve two ends, a left side, right axle shaft is separately fixed at the left side of rear axle stand by bearing, in the right axle sleeve, the interior cover of described manpower flywheel and electric power flywheel is fixed on the pipe box, the pipe box two ends are fixed with flange, pipe box places the left side of crane span structure, between right axle sleeve, the ratchet diff is arranged with the ratchet device of spline in being, its overcoat of ratchet diff is by on the flange that is bolted to the pipe box two ends, a left side, right axle shaft is connected by spline with the ratchet diff at pipe box two ends.
Technique effect of the present utility model is: it has advantage simple in structure, that cost is low, drives because of adopting twin shaft, also has energy-conservation, anti-break away, brake stable and safe and reliable advantage.
