Abstract
The invention discloses a time-sharing drive device for a dual-rear axle commercial vehicle, belongs to the field of commercial vehicle chassis drive, and aims to overcome shortcomings so that a driver can duly convert a drive mode according to detailed road conditions. In the time-sharing drive device for the dual-rear axle commercial vehicle, single-rear axle drive and dual-rear axle drive can be converted at any time. When an airfork 6 drags a big sleeve gear 4 and a small sleeve gear 5 to work in an area A, a torsion of an engine singly drives a rear axle assembly through a flange input shaft 2, the big sleeve gear 4 and a through shaft 3; and when the airfork 6 drags the big sleeve gear 4 and the small sleeve gear 5 to work in an area B, the torsion of the engine is divided into two routes, namely a rear axle and a middle axle, by an inter-axle differential 7 through the flange input shaft 2, the big sleeve gear 4 and the small sleeve gear 5. The time-sharing drive device of the invention directly transmits the torsion from the engine to some drive axle which needs time-sharing drive and an engaging and disengaging gear arranged at the wheel edge of a dead axle is separated from and meshed with a half axle and a hub of the dead axle.
Description
Technical field:
The invention belongs to commercial car chassis transmission field.
Background technology:
The dual-rear axle commercial automobile driving system all is to adopt full-time actuation techniques scheme at present; Its weak point is: road conditions needs whether no matter in running car; Two back axles are operated under the full-time driving condition always, although the doube bridge gear ratio is identical, the relative girth of participating in four groups of tires of driving is discrepant; Add engaged transmission between the axle, gear of too many levels, this is on record for power and the oil consumption severe attrition in the torque transfer process.When reality is used, comprise that engineering truck on average should have the riving condition of 85% above mileage can use single bridge drive pattern to satisfy the operation needs.
Summary of the invention:
The objective of the invention is to solve above-mentioned shortcoming, make the navigating mate can be according to the concrete road conditions of driving, in good time conversion drive mode promptly can be used timesharing drive pattern list bridge to drive to drive the dual-rear axle commercial automobile of changing at any time with doube bridge to can save energy actuating device.
