In the vehicle of the prior art, comprise offroad vehicle, it drives in the vehicle bridge and all is provided with satellite differential, it exists following deficiency: when vehicle driving, if its one side driving wheel is got down hopeless in a quagmire when the wheel-slip phenomenon takes place, because differential design, vehicle then can't travel by self power, can only just can sail by external force.A kind of offroad vehicle of the prior art is equipped with E-Diff in ransaxle, but this E-Diff just pins the wheel that skids, and makes driving wheel running speed relative equilibrium, and on the wheel that does not have driving force to output to skid.
In order to solve above-mentioned deficiency, people have designed the differential mechanism that improves non-skid property.As application number is 86201676, the applying date is on March 22nd, 1986, denomination of invention is spiral differential mechanism, one band spline housing is arranged, accept to drive the circular cone helical gear of square, the shell and this circular cone helical gear that contain differential mechanism are fixed together, and it is characterized in that: the assembly of differential mechanism distributes about symmetrically in spline housing, and moving axis one end of going here and there is a spline rod, cooperate with spline housing, the other end is a transmission nut, between string moving axis and the spline housing spring is housed, and screw axis one end is a spline housing, the other end is a drive screw, screw rod cooperates with the nut of string moving axis, and the splined end of semiaxis cooperates with the spline housing end of screw axis, and with taper pin semiaxis and screw axis being connected is an integral body; The circular cone helical gear is divided into left and right sides two-part with differential mechanism, two-part parts except that the rotation direction of screw pair on the contrary, all the other are symmetry all.Though this patent has certain anti-slip function, its structure is complicated, the cost height, and also non-skid property is undesirable.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, and cost is low, and differential action is good, and is applied widely, the better difunctional driving vehicle bridge of non-skid property.
The utility model is realized above-mentioned purpose by following technical proposals:
The utility model comprises differential mechanism and locking framework, is provided with driving gear in the differential mechanism, and locking framework links to each other with differential mechanism.Locking framework comprise the external gear that is fixed together with driven gear, the internal gear that can be meshed with external gear, with semiaxis, transfer case gearshift mechanism that planetary pinion is connected, semiaxis is provided with key, internal gear be provided with semiaxis on the keyway that matches of key.
Described external gear can be outer spur gear, and internal gear can be interior spur gear.Key is a spline, and keyway is a spline.Described transfer case gearshift mechanism comprises range fork, deciliter bar, spring, brake pulling wire, brake handle.Described differential mechanism is made up of the circular cone driven gear, differential gear, the planetary pinion that link to each other with the vehicle driving gear, is provided with planet pin between the planetary pinion.
Advantage of the present utility model is: at anti-skid structure complexity of the prior art, the cost height, the unfavorable characteristics of skidproof effect, the utility model is provided with manually operated traction aid, this device is realized by being connected locking framework with differential mechanism, semiaxis, transfer case gearshift mechanism that locking framework comprises the external gear that is fixed together with driven gear, the internal gear that can be meshed with external gear, is connected with planetary pinion, semiaxis is provided with key, internal gear be provided with semiaxis on the keyway that matches of key.This simple and reasonable, safe and reliable, cost is low, and differential action is good, and is applied widely, and non-skid property is good.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model structural principle schematic representation.
Specific embodiment
As shown in Figure 1, the utility model comprises differential mechanism, locking framework, and locking framework links to each other with differential mechanism, and differential mechanism, locking framework are provided with shell 24 outward.Differential mechanism is made up of the circular cone driven gear 1 that links to each other with vehicle driving gear 21, differential gear 2, planetary pinion 3, is provided with planet pin 4 between the planetary pinion 3.Locking framework comprises the outer spur gear 5 that is fixed together with circular cone driven gear 1, interior spur gear 6, the semiaxis 7 that links to each other with planetary pinion 3, the transfer case gearshift mechanism that can be meshed with outer spur gear 5, semiaxis 7 is provided with spline 71, interior spur gear 6 is provided with the spline that matches with spline 71, interior spur gear 6 is enclosed within on the semiaxis 7 by spline 71, and can slide.The transfer case gearshift mechanism comprises range fork 8, deciliter bar 9, spring 10, brake pulling wire 11, brake handle 12, slide bar 13, slide bar fixed base 14.
Be provided with bearing 15 between outer spur gear 5 and the circular cone driven gear 1, what link to each other with differential gear 2 is semiaxis 16, and semiaxis 16 is provided with bearing 17, and wheel 18 links to each other with 16 with semiaxis 7 by universal joint 19, semiaxis 20.Circular cone driving gear 21 and 1 engagement of circular cone driven gear link to each other with transmission shaft 23 by driving shaft 22.Certainly, locking framework can also adopt other lock mode, as forms such as expansion set, draw-in grooves.
