Abstract
The utility model relates to a single-stage drive axle with a wheel-side differential lock, comprising an adapter and an air-operated control mechanism. The utility model is characterized in that a fixing gear sleeve is connected with a differential shell by a spline and is located axially by an elastic check ring; the spline of a movable gear sleeve is connected with the corresponding spline on a differential axle and can slide axially; a shift fork is arranged on a shift fork shaft; the piston with a seal ring is arranged inside an air cylinder at the right of the shift fork shaft; and the differential shell is provided with a differential lock indicator light switch. The passing capability of automobile on a slippery road surface is solved; the differential lock locks the differential temporarily, that is to say, the two differential axles are connected into one body so that the two differential axles do not have differential action.
Description
Technical field
The utility model relates to the single-stage drive axle of a kind of belt wheel limit differential lock, belongs to auto manufacturing, is applicable to the vehicle of the heavy single-stage drive axle of coupling.
Background technique:
Usually heavy-duty car travels when bad road surface, when a driving wheel touches slippery ground (mire or ice and snow road), though another driving wheel is on good road surface, but automobile still can not advance, this moment trackslips in the wheel original place on slippery ground, and the wheel transfixion on good road surface.This is because very little at wheel on the slippery ground and the adhesion between the road surface, the road surface can only be very little to this wheel effect the moment of reaction, when driving moment reaches this moment. wheel just trackslips in the original place, though the adhesion between another wheel and the good road surface is bigger at this moment, but because the characteristics of common bevel differential mean allocation moment of torsion, the moment of torsion that this wheel is assigned to can only equate with the moment of torsion on passing to the driving wheel that trackslips, because this moment of torsion is very little, be not enough to overcome running resistance, therefore cause automobile to move ahead.
Summary of the invention:
The purpose of this utility model is to provide the single-stage drive axle of a kind of belt wheel limit differential lock, it has overcome the above-mentioned shortcoming that common bevel differential exists, solved the passing capacity of automobile on slippery ground, by handling differential lock differential mechanism is temporarily pinned, be about to two-semiaxle and be connected as a single entity, make it not produce differential action.
The technical solution of the utility model is achieved in that the single-stage drive axle of belt wheel limit differential lock, is made up of coupling and air pressure operating mechanism, and it is characterized in that: the fixing tooth cover is connected with differential carrier by spline, and uses the circlip axially locating; The spline of mobile tooth cover is connected with corresponding spline on the semiaxis, and can endwisely slip, and shift fork is contained on the declutch shift shaft, in the right-hand cylinder of declutch shift shaft the piston of being with seal ring is housed, and the differential lock indicator light switch is housed on the reducing gearbox.
Good effect of the present utility model is by handling differential lock differential mechanism temporarily to be pinned, and is about to two-semiaxle and is connected as a single entity, and makes it not produce differential action; Avoid wheel-slip that one-sided slippery ground causes, driven hypodynamic phenomenon.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 is return spring, and 2 is the differential mechanism indicator light switch, and 3 is declutch shift shaft, and 4 is piston, and 5 is gas-tpe fitting, and 6 is shift fork, and 7 is semiaxis, and 8 is mobile tooth cover, and 9 is the fixing tooth cover, and 10 is circlip, and 11 is differential carrier.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, the single-stage drive axle of belt wheel limit differential lock, be made up of coupling and air pressure operating mechanism, it is characterized in that: fixing tooth cover 9 is connected with differential carrier 11 by spline, and with circlip 10 axially locating; The spline of mobile fixing tooth cover 9 is connected with corresponding spline on the semiaxis 7, and can endwisely slip, and shift fork 6 is contained on the declutch shift shaft 3, in the right-hand cylinder of declutch shift shaft 3 piston 4 of being with seal ring is housed, and differential lock indicator light switch 2 is housed on the differential carrier 11.
During use, driver-controlled switch, pressurized air just enters cylinder by gas-tpe fitting 5 places, promoting piston 4 moves to left, piston 4 promotes declutch shift shaft 3, shift fork 6, thereby stir mobile tooth cover 8 near fixing tooth cover 9, the end face tooth of mobile tooth cover and fixing tooth cover is meshing with each other, thereby makes semiaxis 7 and differential carrier 11 just be linked to be an integral body.Differential mechanism does not play differential action, and automobile two driving wheels can transmit all torsion torque that is determined by adhesion, makes automobile continue to advance.In the time of the differential mechanism locking, indicator light switch 2 is switched on, and signaling lamp is bright in the operator cabin, notes to remind the driver, after automobile sails normal road surface into, should in time take differential lock.When needs are removed locking, master cock again, emit the pressurized air in the cylinder, shift fork 6, declutch shift shaft 3, mobile tooth cover 8 and piston 4 are by getting back to original position under the effect that is enclosed within the return spring 1 on the declutch shift shaft, differential mechanism is removed locking, recover differential action, meanwhile indicator light switch 2 disconnects, and signaling lamp extinguishes in the operator cabin.
