Medium bridge main speed reducer assembly with through shaft disengagement and engagement device

Abstract

The invention belongs to the technical field of automobile manufacturing, and discloses a medium bridge main speed reducer assembly with a through shaft disengagement and engagement device. The mediumbridge main speed reducer assembly is composed of an inter-axle differential and inter-axle differential lock assembly, a driving bevel gear assembly, the through shaft disengagement and engagement device and an inter-wheel differential and inter-wheel differential lock assembly. The through shaft disengagement and engagement device is additionally arranged at the position of a through shaft of amedium bridge main speed reducer, a drive axle is converted between a 6*4 drive manner and a 6*2 drive manner, a shell body of the medium bridge main speed reducer does not need to be changed, the invested cost is low, and the generalization performance is high. When a vehicle is under a non-load or non-full-load condition, the through shaft disengagement and engagement device is switched off, thus, the input torque of the rear drive axle is zero, the rear drive axle can be lifted, the turning radius of the whole vehicle can be improved, the requirement of vehicle operation for a site is reduced, abrasion of tires can be reduced, the expense of the tires is reduced, and higher economic benefits are brought for a user. The fuel consumption can be reduced by 3% or above for the user every year in the commercial vehicle with the device.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an intermediate axle final reducer assembly with a through-shaft clutch device. Background technique [0002] Article 4.3 of the national mandatory standard "GB1589-2016" clearly stipulates that the maximum allowable total mass of automobiles, trailers and automobile trains should not exceed 49 tons, that is, the maximum allowable total mass limit of 6×4 tractors is reduced from the original 55 tons to 49 tons, with the requirements of this regulation, the overloading of commercial vehicles will be effectively controlled, and the lightweight design of commercial vehicles, the improvement of transmission efficiency, and the saving of fuel consumption will reduce or reduce the cost of vehicles for users. [0003] At present, the most mainstream heavy-duty commercial vehicles with the largest market holdings in China are 6×4 tractors or trucks. Since 6×4 tractors or...
