Four-wheel drive transfer case based on real-time four-wheel drive platform and method thereof

Abstract

The invention discloses a four-wheel drive transfer case based on a real-time four-wheel drive platform and a method thereof. A mesh sleeve device is integrated in a power take-off device of a real-time four-wheel drive system for replacing an electrically-controlled hydraulic multi-plate clutch in a rear differential of the real-time four-wheel drive system. The four-wheel drive transfer case structurally comprises a power take-off shaft, a tapered roller bearing I, a tapered roller bearing II, a driving gear seat, a driving gear, a mesh sleeve, a shifting fork, a tapered roller bearing III,a limiting ring, a locking nut I, a connecting flange, a locking nut II, a tapered roller bearing IV, a tapered roller bearing V, a driven gear, a power take-off gear, a driven shaft, a shifting forkpush rod and a shell. The four-wheel drive transfer case based on the real-time four-wheel drive platform has the characteristics of compact structure of real-time four-wheel drive, and is suitable for the real-time four-wheel drive platform; according to the four-wheel drive transfer case, compared with the electrically-controlled hydraulic multi-plate clutch, the structure of the mesh sleeve issimple, stable and durable, the four-wheel drive transfer case has obvious economy, and the get-out-of-trouble ability of the four-wheel drive transfer case is stronger than a common real-time four-wheel drive system.

Description

technical field [0001] The invention relates to the transmission field of automobile technology, in particular to a four-wheel-drive splitter based on a timely four-wheel drive platform and a method thereof. Background technique [0002] Four-wheel drive means that all four wheels of the car can get driving force. In this way, the power of the engine is distributed to the four wheels, so that wheel slipping is not easy to occur when the road conditions are bad, and the passing ability of the car is greatly improved. Common four-wheel drive (four-wheel drive) systems include: 1. Full-time all-wheel drive, referred to as AWD (short for All Wheel Drive), the specific meaning is: any time the car is driving, all wheels move independently. 2 part-time four-wheel drive (PART-TIME 4WD), which is a four-wheel drive system in which the driver can manually select between two-wheel drive and four-wheel drive. This is also the most common drive mode for off-road vehicles or four-wheel...

AI Technical Summary

Problems solved by technology

[0004] At present, when most timely four-wheel drive transmits power to the front and rear axles, it is limited by the defects of the structure itself, and cannot transmit more than 50% of the power to the rear axle. When dealing with harsh road surfaces, the physical structure limit of four-wheel drive is relatively low.
