Description
Technical field
The utility model relates to a kind of four-wheel-drive vehicle transfer case, particularly a kind of transfer case with parallel axes planet gear type spiral gear limited-slip differential.
Background technique
Transfer case of automobile is the device of a kind of automobile power transmission and conversion, its objective is the driving that realizes the forward and backward bridge of automobile.Differential mechanism in the existing four-wheel drive vehicle transfer case is to adopt a kind of traditional interaxial differential, power is imported by the input shaft in the transfer case, by the gear on the gear driven jack shaft on the input shaft, rotating speed is passed to interaxial differential, output power to the front and back output shaft by the planet wheel in the interaxial differential, sun gear, ring gear again, pass to the propons and the back axle of vehicle again.This differential mechanism can be realized the function that differential and difference are turned round, but has disadvantageous one side, when promptly a certain bridge of four-wheel wagon is absorbed in mire or abominable ground, because adhesion is not enough, will produce and skid, and another bridge is because its influence, driving force does not increase counter subtracting, directly cause the same with slip wheel, cause the tractive force of car load greatly to reduce, and even less than running resistance, so slip wheel runs up, another wheel does not then rotate, and car load comes to a halt.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of transfer case that can avoid driving wheel to skid automatically is provided---the transfer case of band parallel axes planet gear type spiral gear limited-slip differential.
The technical solution of the utility model: a kind of transfer case with parallel axes planet gear type spiral gear limited-slip differential, it comprises the transfer case housing, the input shaft of band gear, the jack shaft of band gear, differential mechanism, the output flange, bearing and seal ring, it is characterized in that: the differential mechanism in the transfer case is band parallel axes planet gear type spiral gear limited-slip differential, it comprises differential gear, the differential mechanism protecgulum, differential casing, the front output shaft of sun gear before the band helical tooth, the preceding planet wheel of three band spiral gears, two wearing pieces, pad, the back planet wheel of three band helical tooths, the rear sun gear of band helical tooth, rear output shaft and differential mechanism bonnet, its preceding planet wheel is meshing with each other with the back planet wheel, simultaneously, sun gear engagement before the band helical tooth on preceding planet wheel and the output shaft, back planet wheel and rear sun gear engagement, between sun gear and the rear sun gear two wearing pieces are arranged before the band helical tooth on the front output shaft, pad has two butterfly spring sheets between two wearing pieces; Gear on the output shaft of the band gear in the transfer case and output shaft are overall structure, and gear on the jack shaft of described band gear and jack shaft are overall structure, and the input shaft of its band gear is meshing with each other by gear with the jack shaft of band gear; Sun gear and output shaft are overall structure before the band helical tooth before the band helical tooth in the transfer case on the front output shaft of sun gear.
In sum, this transfer case compact structure, the passing capacity of raising car load.This kind transfer case is applicable to the automobile of four-wheel drive, light duty cross-country car has particularly adopted the transfer case behind the spiral differential mechanism of parallel axes planet wheel, can reach the sliding function of finite difference, be in when skidding at a wheel, another wheel drives the wheel that drives out of order and guarantees that automobile effectively moves.
