Transfer case capable of realizing quick switching without causing jerking forward

Abstract

The invention discloses a transfer case capable of realizing quick switching without causing jerking forward. The transfer case comprises a box body, a main shaft and a transfer shaft, wherein a beltis arranged between a first sheave wheel and a second sheave wheel to connect the first sheave wheel with the second sheave wheel; a tension shaft is arranged in the box body and at the position between the main shaft and the transfer shaft; the tension shaft penetrates through the belt or penetrate through the part below or above the belt; the tension shaft comprises a front shaft, a rear shaft and a frustum; the frustum is concentrically connected between the front shaft and the rear shaft; a telescopic driving device parallel to the tension shaft is arranged on the outer side of the box body; and a bending plate is arranged between one end of the tension shaft and the end part of the telescopic driving device to connect the tension shaft with the telescopic driving device. According tothe transfer case capable of realizing quick switching without causing jerking forward provided by the invention, the rear shaft is large in diameter, so that the belt is pressed for tensioning to enable the main shaft and the transfer shaft to rotate synchronously, the front shaft is small in diameter, the belt is kept in a loosened state without participating in transmission, the switching smoothness is improved by utilizing the frustum, the problem of jerking forward is avoided, and the switching speed is high.

Description

technical field [0001] The invention relates to the field of transfer cases, in particular to a transfer case with fast switching and no disturbance. Background technique [0002] The transfer case is a device that distributes the power of the engine. By switching, the power can be output to the rear axle, or to the front axle and the rear axle at the same time. [0003] Ordinary transfer cases are usually rotated by gears or chains, which are heavy in weight, high in energy consumption, and require gear oil for lubrication, resulting in high maintenance costs. The switching is relatively blunt or needs to be stopped for operation. The speed is slow and the vibration is large, which reduces the operation comfort. Contents of the invention [0004] The purpose of the present invention is to provide a transfer case with fast switching and no intrusion, which reduces the cost and improves the quickness and stability of the switching operation. [0005] For reaching this pur...
