Abstract

The invention relates to the technical field of vehicles, and in particular relates to a full-time four-wheel drive transmission system of a small and medium-sized all-terrain off-road vehicle. The transmission system comprises a main speed reducer, a CVT and a front differential; the main speed reducer is connected with an engine through a damping part, the input end of the main speed reducer is in transmission connection with the engine through the CVT, one output end is connected with the front differential through a transmission shaft, the front differential is connected with front wheels through half shafts, and the other output end is connected with rear wheels through half shafts; a protection device is mounted at the joint of the transmission shaft and the main speed reducer as well as the front differential or on the CVT transmission and is used for protecting the transmission shaft, the CVT, the main speed reducer and the front differential; an inter-axle differential mechanism and a rear axle differential mechanism which are in meshed connection through a bevel gear set are integrated in the main speed reducer; the system has the beneficial effects that the three differential mechanisms of the system are integrated in a small effective space, the steering performance is guaranteed while power distribution is achieved, and better passing capacity and steering performance are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a full-time four-wheel-drive transmission system of a small and medium-sized all-terrain off-road vehicle. Background technique [0002] Today, with the increasing development of the automobile industry, various types of automobiles are widely used in all walks of life; it is convenient and enriches production and life. Among them, small and medium-sized all-terrain off-road vehicles have entered the public's field of vision due to their excellent off-road performance and price advantages, and can be seen in many off-road events and entertainment projects. [0003] However, in the domestic all-terrain off-road vehicles, the rear-drive mode is often adopted. Such all-terrain off-road vehicles not only have poor passing ability, but also have insufficient steering performance. Based on this background, we designed this set of full-time four-wheel drive system. Contents of the i...
