The differential components are symmetrically arranged at two sides of the vehicle body so as to release the effective loading space inside the vehicle body; and the wire rope transfers the motion of the two components so as to shorten the length of the two input shafts.
Description
Technical field
The present invention relates to a kind of detection vehicle bevel gear differential.
Background technology
When probe vehicles is advanced on rugged celestial body surface, the amplitude of fluctuation difference of both sides rocking arm, thereby the disturbance difference that car body is produced.In order to reduce the influence that the rocking arm pivot angle changes the car body attitude, guarantee the stationarity of payload platform in the probe vehicles driving process, often adopt the mode of 2 suspentions to connect main car body and both sides rocking arm, and come of the influence of average both sides rocking arm pivot angle main car body by differential balance mechanism.Publication number is CN101033008A, open day be September 12 in 2007 day, be called four-wheel or six and take turns and adopted a kind of concentrated symmetrical expression spur bevel gear wheel differential attachment in the application for a patent for invention of differential torsion rod spring suspension type vehicle-carrying mechanism, this differential attachment is the reverse application of vehicle planetary bevel differential, both sides suspension pivot angle is dual input, the tie-rod of bevel planet gear links to each other with car body as single output, thereby realizes the linear averaging of main car body pitch angle.But because this differential attachment is installed in car body middle part, therefore occupy certain payload space, and two semiaxis are slender axles, stressed bad.
Summary of the invention
The objective of the invention is to take turns differential torsion rod spring suspension type vehicle-carrying mechanism in order to solve existing four-wheel or six, owing to adopted centralized symmetrical spur bevel gear wheel differential attachment, and this device occupies car body in-to-in payload space, and two stressed bad problems of elongated semiaxis provide a kind of separable differential balance mechanism of detection vehicle finishing bevel gear cuter cord drive.
The hybrid differential balance mechanism of detection vehicle finishing bevel gear cuter rope of the present invention is by two differential assemblies, first rope sheave, steel rope, second rope sheave and car body are formed, described two differential assemblies are symmetricly set on the both sides of car body, each differential assembly is by center bevel gear, input shaft, bevel planet gear, adapter shaft, pinion carrier and rocking arm are formed, described rocking arm is packed on the input end of input shaft, the mouth and the pinion carrier of described input shaft are hinged, described center bevel gear is packed on the mouth of input shaft, described center bevel gear and bevel planet gear engagement, described bevel planet gear is packed on the input end of adapter shaft, described adapter shaft and pinion carrier are hinged, described first rope sheave and described second rope sheave are packed in respectively on the mouth of two adapter shafts, one end of described steel rope is on first rope sheave, the other end of described steel rope is on second rope sheave, and two pinion carrier symmetries are packed in the both sides of car body.
The present invention has following beneficial effect: one, the present invention is installed in the both sides of car body with the differential assembly symmetry, thereby reduces the taking of car body inner space, and discharges payload space in the car body; The present invention adopts the motion of two assemblies of wire rope transfers, has shortened the length of two input shafts, has improved the rigidity of input shaft, makes overall weight reduce.Two, the present invention is easy to operate, commonality good.
