Embodiment Construction

[0020] The core of the present invention is to provide a hydraulic anti-skid self-locking differential. When the hydraulic anti-skid self-locking function makes the driving ability of one wheel fail, the other wheel can still provide driving force to improve the trafficability of the vehicle. The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the driven spiral bevel gear 17 is connected with the differential left case 12 and the differential right case 27 by bolts 14 . Four pin shafts 22 are embedded in the circular holes of the differential gear right housing 27, and are fixed by cylindrical pins 21. Spherical spacer 23, bevel gear 24 are enclosed within on pin shaft 22 successively, and spherical spacer 23 outer diameters have projections, are placed in the groove of differential gear right shell 27 during installation, prevent...

Abstract

The invention discloses a hydraulic antiskid self-locking differential mechanism, and belongs to the technical field of differential mechanisms. The hydraulic antiskid self-locking differential mechanism comprises a differential mechanism body and a hydraulic differential lock matched with the differential mechanism body, and the hydraulic differential lock comprises a differential lock hub, a piston rod, a pressure plate and a spline sleeve arranged on a left half shaft inside the differential mechanism body. A driving friction plate and a driven friction plate are arranged outside the spline sleeve. When a tire skids, a piston pushes the piston rod under the action of pressure oil and then pushes the pressure plate to compress the friction plates, a driven spiral bevel gear directly transfers power to the half shaft through a differential mechanism shell, and the differential mechanism body does not work at this moment. The hydraulic antiskid self-locking differential mechanism has the advantages that the structure is simple, manufacturing is easy, and the differential and torque-differential-free function of a common differential mechanism is achieved; when a vehicle skids or falls into mud, the common differential mechanism can be completely locked through the antiskid self-locking function, all torque can be transferred, the vehicle is prevented from skidding, and the trafficability characteristic of the vehicle is improved.

Description

technical field [0001] The invention relates to a differential, in particular to a hydraulic anti-skid self-locking differential. Background technique [0002] Ordinary differentials have the torque transmission characteristics of "differential speed without differential torque", which allows the half shafts on both sides to rotate at different speeds, reducing the friction between the tire and the ground. If the friction torque is not included, it can be considered that the torque distributed to the left and right half shafts is equal . However, the "differential speed is not bad torsion" characteristic of ordinary differentials will have an adverse effect on mechanical driving. When the vehicle falls into a mud pit, it will slip due to insufficient adhesion. At this time, the driving force of the other wheel will not increase, but will be reduced to the same as the slipping wheel, so that the traction force of the whole machine is greatly reduced. If the traction force c...
