All-terrain vehicle and two-wheel and four-wheel drive switching protection device thereof

Abstract

The invention provides a two-wheel and four-wheel drive switching protection structure of an all-terrain vehicle. An elastic supporting structure is arranged at the shifting end of a shifting sleeve shifting rod; when a spline shifting sleeve is engaged and clamped, and after a bridge motor is driven in place, the shifting end of the shifting sleeve shifting rod deforms through an elastic supporting structure, and meshing impact caused by rigid connection is reduced; and meanwhile, the elastic supporting structure provides continuous pushing force for the shifting sleeve shifting block, afterthe spline shifting sleeve corresponds to the half axle gear in position, the elastic supporting structure pushes the spline shifting sleeve in place through the elastic pushing force of the elastic supporting structure, the shifting end of the shifting sleeve shifting rod returns to a normal station, and the driving safety of the axle motor in the two-wheel and four-wheel drive state switching process of the all-terrain vehicle is improved. The invention further provides an all-terrain vehicle.

Description

technical field [0001] The invention relates to the technical field of all-terrain vehicles, and more specifically relates to an all-terrain vehicle and a protection device for switching between two and four-wheel drives. Background technique [0002] The English of all-terrain vehicle is All Terrain Vehicle, which is a vehicle suitable for all terrains. The abbreviation is ATV, commonly known as "beach vehicle", also known as all-terrain four-wheel off-road locomotive. [0003] All-terrain vehicles adapt to different road conditions, and are usually set to a four-wheel drive structure. Its driving state can be switched between two-wheel drive or four-wheel drive according to road conditions. The driving functions of existing all-terrain vehicles are usually set to two-wheel drive, four-wheel drive and The four-wheel drive is locked in three states, and the switching of the three states is achieved through the sliding of the spline dial sleeve fitted on the half shaft, and t...

AI Technical Summary

Problems solved by technology

The existing bridge motors are large in size, and the internal structure of the motor requires accurate positioning of the gears, otherwise it is easy to cause the gears to be staggered during assembly and need to be reassembled

[0004] And the bridge uses the motor action to push the spline dial to mesh with the half-shaft gear. The internal motor of the motor is easily damaged due to long-term work, the service life is low, the energy consumption is high, and the internal transmission parts of the motor are easily damaged.

At the same time, after the spline dial is driven by the bridge motor, the position of the spline dial needs to be detected. The existing detection structure is prone to inaccurate detection positions, and it is difficult to accurately prompt the driving status of the vehicle, which affects work stability.
