A four-wheel-drive off-road vehicle with a wheel adjustment linkage

Abstract

An object of the present invention is to provide a four-wheel-drive off-road vehicle with a wheel adjustment linkage. The vehicle includes a frame, a vehicle seat, a steering wheel, a steering lever,a steering driving gear, a front wheel adjustment linkage and a rear wheel adjustment linkage, and is characterized in that: the front wheel adjustment linkage comprises a front wheel swing cross member, Steering driven gear, two front wheel longitudinal connecting arms, two front wheel transverse connecting arms, two front drive wheels, two front swing tie rods and two front steering tie rods, each front wheel longitudinal connecting arm is provided with a front swing joint, a front shock absorbing joint, and a rear wheel adjustment linkage similar in structure to the front wheel adjustmentlinkage. The wheel connecting arm of the off-road vehicle is based on an adjusting linkage mechanism, and can adjust the up-down left-right swing of the front and rear wheels according to the terraincondition to adapt to the terrain, and can effectively absorb vibration, so that the whole vehicle body can not be influenced by the complex terrain, and friction and impulse can be reduced, so as tokeep the vehicle body in a stable driving state.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a four-wheel drive off-road vehicle with a wheel adjustment linkage mechanism. Background technique [0002] The continuous development of modern society and the ever-changing life changes have greatly improved people's living standards and quality of life. Off-road vehicles have become a relatively common means of transportation in our lives. As more and more people go out on holidays, off-road vehicles of various models emerge in endlessly, especially in various rough roads and desert walking, off-road vehicles for entertainment are the most popular and popular, but now there are The off-road vehicles on the road can basically only cross relatively complicated road surfaces, and cannot do off-road in the true sense.

As more and more people go out on holidays, off-road vehicles of various models emerge in endlessly, especially in various rough roads and desert walking, off-road vehicles for entertainment are the most popular and popular, but now there are The off-road vehicles on the road can basically only cross relatively complicated roads, and cannot do off-road in the true sense.

For climbing, the current off-road vehicles can only cross relatively small slopes. For mountain roads with relatively large slopes, current off-road vehicles cannot easily cross them at all. Drivers must drive carefully. Overturning will cause great harm to people; for the unevenness of the road surface, the current off-road vehicles can only reduce the vibration of the body to a certain extent, so that the driver is in a tense environment and prone to fatigue driving; There is not much improvement. The four-wheel connection support structure is a unified fixed mode, so the shock absorption effect has not been effectively improved. Although the road driving is completed by four-wheel drive, the driving loss and performance It has not been improved, especially for the height change of the road surface, which makes the center of gravity of the entire body shake, and the connecting arms of the four wheels cannot change the driving form according to the road conditions, which invisibly restricts the driving of the vehicle and cannot adapt to various conditions. Driving on a complex terrain will increase the friction between the various supporting parts of the vehicle, and the impact will be more severe, which will lead to the inability to effectively guarantee the stability and safety of the entire vehicle body.
