Abstract
The utility model provides a dual-drive type automobile differential gear for preventing the automobile driving wheels slipping, which solves the problem that the left and the right half shaft of the automobile differential gear can not be locked. The utility model is provided with a differential gear case, in which a cross shaft is arranged, and a planetary gear is arranged on the cross shaft. A half shaft gear which is matched with the planetary gear is installed in the differential gear case and half shafts are arranged and hinged on the half shaft gear. The utility model is characterized in that the front of one of the half shafts is provided with a shifting shaft whose front end extends into the differential gear case and is connected with the half shaft gear. A key-slot which is matched with the shifting shaft is arranged on the cross shaft and the end part of the shifting shaft is provided with a shifting fork. The dual-drive type automobile differential gear has the advantages that one half shaft is provided with the shifting shaft, so when the highway condition is bad, the shifting shaft can be connected with the cross shaft by the shifting fork to lock the differential gear, which prevents the wheels slipping, and the lock can be conducted at any time during the automobile travel; the utility model has simple structure and easy operation.
Description
Technical field
The utility model belongs to a kind of differential mechanism, particularly a kind of double-driving automobile differential that prevents that automobile driving wheel from skidding.
Background technique
Differential mechanism is the vitals in the automobile driving system.At present, most widely used in automobile driving system is symmetrical bevel differential, and it mainly is made up of differential mechanism shell, cross axle, semiaxis, planetary pinion and differential gear etc.This differential mechanism adopts planetary gears, to realize the differential of left and right sides semiaxis.The subject matter that it exists is, can only be between the semiaxis of the left and right sides mean allocation moment of torsion, and can't realize poor power between the semiaxis of the left and right sides, thereby make automobile on the bad road surface of the condition of adhering to, particularly on two coefficient of attachment road surface, pass through poor performance, seriously influenced the mobility of automobile.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes the problem that existing automobile differential left and right sides semiaxis can not locking, and a kind of double-driving automobile differential that prevents that automobile driving wheel from skidding is provided.
The utility model has a differential mechanism shell, in the differential mechanism shell, cross axle is housed, planetary pinion is housed on the cross axle, the differential gear that matches with planetary pinion also is housed in the differential mechanism shell, semiaxis is housed on the differential gear, be connected for key between differential gear and the semiaxis, its special way is, the front end of a semiaxis is equipped with shifting axle therein, the front end of shifting axle extend in the differential mechanism shell, and be connected with differential gear, the keyway that matches with shifting axle is arranged on cross axle, also have a shift fork in the end of shifting axle.
Between differential mechanism shell and shifting axle, reposition element is housed, shifting axle is automatically reset, remain on the non-lock position.
Advantage of the present utility model is, at the front end of a semiaxis shifting axle is installed, and does not change the basic structure of automobile differential, do not influence original performance of automobile differential yet, when road conditions were good, the differential mechanism proper functioning was when road conditions are bad, can shifting axle be connected with cross axle by shift fork, with the differential mechanism locking, prevent wheel-slip, and, in the process that automobile is advanced, can control simple in structure, handiness at any time.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Schematic representation when Fig. 2 is the utility model locking.
Embodiment
As shown in Figure 1, the utility model has a differential mechanism shell 3, and differential mechanism shell 3 is a two halves formula structure; Cross axle 5 is housed in differential mechanism shell 3, planetary pinion 4 is housed on the cross axle 5; The differential gear 2 that matches with planetary pinion 4 also is housed in differential mechanism shell 3, semiaxis 1 is housed on the differential gear 2, described semiaxis has two, and one long, and what be that 1, one of semiaxis lacks is semiaxis 10, is connected for key between differential gear 2 and the semiaxis 1; Front end at semiaxis 10 is equipped with shifting axle 6, and for key is connected, the front end of shifting axle 6 extend in the differential mechanism shell 3, and is connected with differential gear 2 between shifting axle 6 and the semiaxis 10, is connected for key between shifting axle 6 and the differential gear 2; The keyway that matches with shifting axle 6 is arranged on cross axle 5, between differential mechanism shell 3 and shifting axle 6, reposition element 7 is housed, described reposition element 7 is helical springs, reposition element 7 also can adopt other forms of elastic element, reposition element 7 automatically resets shifting axle 6 after handling end, remain on the non-lock position; Also have a shift fork 9 in the end of shifting axle 6, shift fork 9 is stirred shifting axle 6 and is travelled forward under the manipulation of driver, makes the front end of shifting axle 6 enter into the keyway of cross axle 5, as shown in Figure 2, and with the differential mechanism locking; Described shift fork 9 is installed on the rotatingshaft, drives it by rotatingshaft and swings in operating range, realizes the operation to shifting axle 6, and the rotation of rotatingshaft can be realized by electromagnetism, pneumatic or hydraulic element; A thrust-bearing 8 also is housed on semiaxis 10, and thrust-bearing 8 is between shifting axle 6 and shift fork 9, so that when shifting axle 6 rotations, prevent that shifting axle 6 and shift fork 9 from wearing and tearing mutually.
Claims (3)
