The utility model discloses a simple mechanical differential lock which comprises a driving shaft, a driving gear, a driven gear, planetary gears, output gears, output shafts and lock catches. The simple mechanical differential lock is characterized in that the driving shaft is a power output end, the driving gear is arranged at one end of the driving shaft and meshed with the driven gear, the planetary gears are fixed in the middle of the driven gear, the number of the opposite output gears is two, the output shafts are arranged on the outer sides of the two output gears, the output gears are fixedly connected with the output shafts and are pressed on the planetary gears under pressure of the output shafts, and the lock catches are arranged on the outer sides of the two output gears. The output shafts can slightly move towards the two sides, and the tooth depth of each output gear is larger than the total displacement of the output shafts on the two sides. The lock catches are arranged on the other sides of the output shafts and fixed on a differential mechanism through micro-elasticity components. The lock catches are arranged to achieve the locked state of the differential mechanism so that when one tyre slips, the output shafts on the differential mechanism can be locked, and passing ability and cross-country ability of vehicles are improved.
Description
Technical field
The utility model relates to a kind of device of automobile transmission part self-locking, specifically a kind of all-gear mechanical differential lock.
Background technique
The driving type of automobile is mainly divided into entirely drives and partly drives two kinds, and from safety perspective, the vehicle of entirely driving has higher Security; Taking our common four-wheel car as example, can be divided into two drive, four-wheel driven car.When in the identical situation of condition, as: car weight, road surface situation and tyre type, travelling state etc., the mean value of the two required frictional force of single driving wheel of driving, reach the mean value that doubles the required frictional force of the single driving wheel of four-wheel driven car, be used for driving Vehicle Driving Cycle, and wheel equates with the maximal friction on ground, therefore in the time that two frictional force of driving tire and ground reach maximal friction and occur the dangerous situations such as whipping, sideslip, understeering, ovdersteering, four-wheel driven car still can normally travel, but can face another one problem when Vehicle Driving Cycle, when driving wheel skids, such as: ice and snow road, sand ground, when the situations such as driving wheel is unsettled, vehicle cannot pass to driving force on hesive driving wheel, and cause vehicle to travel, this often occurs in the time of poor condition of road surface or field, and now, there is skidding in any one in four driving wheels of entirely driving, vehicle all cannot normally travel, and two any one of driving in two driving wheels are while occurring skidding, vehicle also cannot normally travel, but two two supporting rollers of driving skid and do not affect normally travelling of vehicle, so, entirely drive to occur that the probability of vehicle slip is two one times of driving, therefore consider to vehicle configuration differential lock, by the driving wheel locking skidding, prevent its idle running, by transmission of power to hesive driving wheel, vehicle is extricated oneself from a predicament, so, in the time entirely driving to dispose differential lock, drive with respect to two, maximum Security and passing ability will be there is.Present differential lock is mainly divided into the mechanical differential lock of pure mechanical structure and utilizes electronic equipment monitoring vehicle wheel rotational speed poor, and utilize the skid EDS of driving wheel of mechanical structure locking, more representational in the mechanical differential lock of pure mechanical structure is Tosen differential lock and viscosity coupling differential mechanism, Tosen differential lock has linear locking, the feature such as be quick on the draw, but cost of production is high, and power transfer efficiency is low, be mainly used in high-end vehicle, and generally do not use at bridge differential lock; Viscosity coupling differential lock, has that cost of production is low, fuel economy high, but slow in reacting.EDS, by friction plate locking slip wheel, have the advantages such as cost of production is low, linear locking, but fuel economy is poor; And present a large amount of electronics clutch type differential locks that use exist fuel economy poor, the problem such as the reaction time is still relatively long, electronic equipment hidden danger, is not suitable for front-rear axle differential lock, generally coordinates brake system to use.
The automobile of rear wheel drive, the rotating speed of its differential mechanism left and right semiaxis is consistent with the rotating speed of differential casing in the situation that of the straight-line travelling of normal road surface, but when automobile turning travels, travels or when low adhesion road traveling at uneven road surface, driving wheel is in adhesion deficiency, both sides wheel is interior mobile distance difference at one time, occurs monolateral skidding, and makes automobile running and turns to difficulty, power consumption increases, and has increased the wearing and tearing of some parts and wheel in transmission system.This problem is to drive respectively two semiaxis of automobile and wheel to solve by differential now, and existing differential mechanism kind is a lot, as traditional bevel planet gear and straight-tooth wheeled, the reaction of moment of torsion induction differential mechanism is fast, can realize real AWD, but cost is high, power consumption is large.Stickiness manifold type differential mechanism cost is low, and volume is little, but time sharing, at ordinary times with two drive equally, adds stickiness manifold type differential lock drive the pattern of trailing wheel by the forerunner of most employing, and in the time that front-wheel skids, maximum can only be transmitted 50% power to rear axle.Electronics clutch differential mechanism locking, price is higher.Also lack at present one simple in structure, with low cost easy to use, Simple mechanical differential lock safely and effectively.
Model utility content
The utility model, just for above-mentioned deficiency, provides a kind of simple in structure, with low cost easy to use, Simple mechanical differential lock safely and effectively.
For achieving the above object, the technical solution adopted in the utility model is:
Simple mechanical differential lock, comprise driving shaft, driving tooth, driven tooth, planet tooth, output gear, output shaft, snap close, it is characterized in that driving shaft is clutch end, driving tooth is arranged on driving shaft one end, and driving tooth engages with driven tooth, and planet tooth is fixed on driven tooth intermediate portion, output gear is relative two, two output gear arranged outside output shafts, output gear is fixedly connected with output shaft and is pressed together under the pressure of output shaft on planet tooth, and two output gear arranged outside have snap close.Output shaft can be made microdisplacement to both sides, and output gear tooth depth is greater than both sides output shaft total displacement amount.Snap close is arranged on output shaft opposite side.Snap close is fixed on differential mechanism by micro-elasticity parts.
The utility model is realized the locking state of differential mechanism by snap close is set, thereby in the time of certain tyre slip, output shaft that can locked differential mechanism, improves passing ability and the cross-country ability of vehicle.
