Abstract

To the application for a utility model “Mechanism of blocking the cross-axle differential of a vehicle”.

This decision relates to the automotive industry. A mechanism is proposed for locking the cross-axle differential of a vehicle, comprising a differential box consisting of two cups: right and left in the direction of travel of the vehicle, a cross on which gears-satellites are installed with the possibility of free rotation, which are engaged with half-axle gears of the right and left wheels, half-axles freely passing through the hole in the differential box and engaged with the axle gear on the floor, on the axle shaft from the right side of the differential box by means of w itsevogo compound movably mounted clutch, clutch actuator carried by a mechanical or hydraulic mechanism having a fork and a lead switch on.

The result of this invention was to increase the patency of the car by transmitting the same moments to both wheels of the vehicle.

Description

This decision relates to the automotive industry.

An analogue of the solution is the differential of the vehicle described in the patent for a utility model (RF Patent No. 52779, BKK 17/16, published on 04/27/2006). It consists of a cone-shaped housing, consisting of two halves connected in a plane perpendicular to the axis of rotation of the housing, two semi-axial gears, ten worm-type satellites, which are arranged in two rows, right and left, parallel to the axis of rotation in specially made housing grooves and pairwise engaged between themselves. Here, partial blocking is carried out, which in some cases is ineffective.

The prototype of the invention is the differential described in the book of A. Bogatyrev and others. "Cars." - M.: KolosS, 2004. on p. 266. It consists of a differential box, consisting of two cups of the right and left in the direction of travel of the car, a cross on which gears-satellites freely rotate, engaged with half-axis gears of the right and left wheels, half-axles that freely pass through the hole in the differential box and enter meshing with a semi-axial gear.

The main disadvantage is the following: if one of the wheels has insufficient adhesion with the road surface, the same moment is transmitted by both wheels. The sum of these points may not be enough to overcome resistance to movement. Then the wheel standing on the road with low grip stalls, and the wheel standing on the road with high grip is motionless. These shortcomings are eliminated by the proposed solution.

The task at hand is to increase the cross-country ability of a car. Technical result: transmission of the same moments to both wheels of the car by blocking the cross-axle differential.

This technical result is achieved in that the locking mechanism of the cross-axle differential of the vehicle, comprising a differential box, consisting of two cups: right and left in the direction of travel of the vehicle, a cross on which satellite gears freely rotate, engaged with the axle gears of the right and left wheels, half shafts, freely passing through the hole in the differential box and meshing with the half gear, is equipped with a locking mechanism, in which the side shafts the right cup of the differential box by means of a spline connection, a movable clutch is installed, teeth are cut at its end, interacting with the teeth cut on the end of the right cup of the differential box, the clutch is driven by a mechanical or hydraulic mechanism containing a fork and a drive leash acting on the second end of the movable clutch . The slots on the half shaft where the clutch is installed are elongated by the size of the clutch stroke. As a result of the operation of this mechanism, the axis movement begins to be transmitted directly to the differential case, as a result of which the differential is blocked and the same torque is transmitted to both wheels.

The proposed cross-axle differential of the vehicle is shown in the drawing. It consists of the right 1 and left 2 cups of the differential box, cross 3, on which the gears-satellites 4 freely rotate, engaged with the semi-axial gears 5, 6 of the right and left wheels, half-axles 7, freely passing through the hole in the differential box and engaged with the axle gear, on the axle shaft from the side of the right cup of the differential box by means of a spline connection

the movable coupling 8, teeth 9 are cut at its end, interacting with the teeth 10 cut at the end of the right cup of the differential box, the drive of the coupling is carried out from a mechanical or hydraulic mechanism containing a fork 11 and a lead 12 that acts on the second end of the movable coupling, splines 13 on the half shaft where the clutch is installed, are made elongated by the size of the clutch stroke.

The mechanism for locking the cross-axle differential of a vehicle works as follows: using a clutch drive, which can include either a clutch lever with a cable system, or a main and executive hydraulic cylinder, or an electric drive, a force is applied to the fork 11, it moves the movable clutch through the clutch 12 8 along the slots 13 of the semiaxis 7 until the teeth 9 of the movable coupling 8 with the end teeth 10 of the left cup of the differential box mesh, the movement of the axle shaft begins to be transmitted directly to the differential housing ala whereby the differential is locked and the wheel is transmitted to both the same torque.
