Auxiliary driving system and vehicle

Abstract

The invention discloses an auxiliary driving system and a vehicle. According to the embodiment of the invention, the auxiliary driving system is constructed on the basis of a parallelogram mechanism, the rack part and a framework opposite to the rack part of the of the parallelogram mechanism can keep parallel all the time, so that bearing of a supporting framework is distributed relatively evenly in the front and back directions and not affected by opening stroke. When in the opening state, the auxiliary driving system is used for extricating of the vehicle or auxiliary driving under a certain road condition; and when in a folded state, greater influence on traversability of the vehicle is reduced, so that the auxiliary driving system can be always prepared on the vehicle, and the situation that the auxiliary driving system is mounted only when the vehicle is caught in a sandy land and the like is not needed. The auxiliary driving system can effectively increase the friction area and friction ability, so that the auxiliary driving system is used for improving the extricating ability.

Description

technical field [0001] The invention relates to an auxiliary running system for a vehicle and a vehicle using the driving system. Background technique [0002] Driving system, the full name of driving system of automobile chassis, its basic composition includes vehicle frame, axle, wheel and suspension, because the present invention is used for auxiliary driving system, borrows the existing framework term of driving system, and does not need to have the complete system of driving system. [0003] Vehicle travel may face bad road conditions or no road conditions, which may cause unexpected situations, such as muddy land, sand and gravel land. [0004] When a car is trapped in muddy or sandy ground, drivers often drive the car slowly to increase the friction between the tires and the ground to get the car out of trouble. And when can't realize getting out of trouble by this, just need to rely on external force, for example other personnel assists to promote automobile, uses w...

Problems solved by technology

Its body lifting system is only used to lift the chassis to a certain height, and then rely on the driving system to get the vehicle out of trouble. However, under this condition, the lifting of the chassis will reduce the friction between the driving system and the ground, making the vehicle in a certain position. a more serious uncontrollable state

[0006] Chinese patent document CN205344359U discloses a car tire pit self-rescue escape device with a remote control, which mainly controls the different working states of the escape device by being provided with a control mechanism and its remote control. , the passenger installs it on the tire of the motor vehicle, it cannot be directly installed on the motor vehicle, and it is driven with the vehicle

In addition, for example, the front axle of a car is an integral part of the steering system, and is usually constructed as a half shaft. The installation space of the half shaft itself is very limited, and it is not easy to realize the assembly of this type of escape device.

[0007] Chinese patent document CN105922826A discloses a trapping device roughly similar to the trapping device claimed in Chinese patent document CN205344359U, all of which need to temporarily install the trapping device on the wheel, and provide a new tire according to its radial profile larger than the tire. The support provided by CN105922826A is a number of support rods with ball heads, which cannot provide continuous support, and the ability to get out of trouble is very limited

This type of structure is simpler than the aforementioned several escape devices, but it also needs to be installed on site. If there is water accumulation at the trapped point, its installation will be very difficult

And its escape depends on the extra torsion force on a certain point (where the protrusion is located). When the trapped situation is relatively serious, it cannot provide continuous support, resulting in the failure of escape.
