Description

Wheel is with adding hanging cross-country track system

Technical Field

The invention relates to the field of automobile accessories, in particular to a wheel-mounted off-road crawler system.

Background

The conventional common wheeled vehicle is easy to get stuck, skid and even out of control on non-paved roads such as ice and snow, muddy slopes, wet and soft roads and the like, and the driving safety and the off-road capability are seriously influenced. Therefore, the multifunctional cross-country crawler system for the vehicle has strong practical significance. Cross-country track, compare prior invention: the existing similar patents are integrated, and compared with the design scheme of the inventor, the method has the following defects: the single weight is large, the single volume is large, and the single person is difficult to load, unload and carry. The device is difficult to install under severe road conditions; if the pavement is additionally arranged in advance, the unnecessary crawler running state is carried out, the use experience and the practicability are seriously influenced, and the service life of the crawler is seriously consumed. How to strengthen the braking and driving requirements of the dark ice hard slippery road surface is not considered. The situation that the bottom of the scratch vehicle is blocked to rotate when the crawler runs at a large angle is not considered. When the tire is actually installed, the inner side part of the tire is turned upwards and is difficult to connect. When the lifting jack is installed, the tire is lifted by the lifting jack, and the lifting jack is difficult to operate on soft ground and is easy to incline. The jack is not suitable for being used on soft ground. Because the mounting height under the tire required by the prior patent is not small and is estimated to exceed 15CM, the suspension stroke of the automobile, particularly the suspension stroke of an off-road vehicle, is generally large, after the tire is jacked, the stroke is released, the required jack operation stroke is greatly increased, the jacking operation difficulty is greatly increased, and the body on the jacking side is seriously inclined; even beyond the working height of conventional jacks, making installation difficult.

The working principle of the invention is as follows: the system increases the original tire grounding area through the crawler belt to prevent the vehicle from being trapped; the gear teeth prevent the vehicle from slipping out of control on hard sliding road surfaces such as dark ice road surfaces and stably driving and braking on hard slope road surfaces in surface slip.

The main functions are as follows: greatly improves the cross-country ability of the wheeled vehicle and the running safety on wet and slippery road.

The technical points are as follows:

the wheel is attached to the wheel, is convenient to assemble and disassemble, is suitable for being additionally assembled on various wheeled vehicles, and has strong applicability;

except that some models need to strengthen the steering strength of the steering wheel, the vehicle does not need to be refitted.

The machine is purely mechanical and is durable and reliable.

The front and rear tracks are separated, so that the volume and weight of the single body are reduced, the mounting difficulty is reduced, and the carrying is convenient.

The driving wheel is used for pressing the tire to obtain power;

the reliable running capability and braking performance of the hard road surface in surface sliding can be obtained through the gear.

The ground contact area is increased by the crawler belt.

The original wheel shock absorption and tire buffering are completely used.

The working state of the crawler can be determined by adjusting the distance between the front and rear connecting adjusting rods, and the ground clearance of the vehicle and the ground contact area of the crawler are adjusted.

When the vehicle sinks, the tire can be automatically pressed to work. The adjusting rod is manually adjusted to force the gear to work when the surface slides on the hard road surface.

If the crawler belt needs to work, the gear can damage the road surface, and the gear can be detached independently.

Because the unsprung weight is increased after the crawler belt is hung, the crawler belt system is not recommended to be hung on a pavement. It is recommended to be hung when entering into bad road conditions.

The method mainly comprises the following steps:

the axle adjustable rod: with wheel axle interface base another application patent connection application number 202021563850X, hang and tightly whole and the whole steering dynamics of reinforcing of track spare, the system drops when preventing that the vehicle cross country tire is unsettled. Is disposed only on one side of the wheel outer side plate. The inner side of the wheel plays the same role by the lower arm hanging rail frame

Adjusting a limiting reinforcing groove of the rod: and the steering wheel is fixed on the outer side of the outer side plate and matched with the axle adjustable rod to strengthen the steering force of the adjusting rod along the direction of the wheel.

Front crawler belt piece arranged at front part of wheel and rear crawler belt piece arranged at rear part of wheel

The front and rear caterpillar band parts are symmetrical in main structure. Comprises the following steps:

the left and right structure side plates and a plurality of fixing bars for connecting and installing the left and right structure side plates.

Driving wheels in contact with the wheels: the trapped vehicle is automatically or manually forced to adjust and press down and contact with the wheels so as to obtain the power of the wheels and pull the crawler belt to rotate; and driving the main gear to rotate through the coaxial external gear. The driving wheel A simply pulls the crawler through the wheel roller, and wheel grains on the outer surface of the wheel roller are matched and correspond to outer patterns of the crawler. The driving wheel B extends the main shaft to the outside of the side plate on the basis of the wheel A, and the outer part of the side plate is provided with an outer gear to drive the main gear to rotate. The driving wheel can be provided with a plurality of driving wheels according to the outer diameter of the tire to achieve the required contact tension.

Pinch roller and follower roller: the track is limited in running route and supported. A plurality of the components can be arranged according to the requirement.

The track adopts an externally-discharged slurry pattern.

Track pinch roller and pinch roller shaft groove: the track is automatically pressed under the pressure of the wheels, and the pressing elasticity is reacted to the tire to act as a driving wheel.

Prevent rubbing the wheel: prevent the rigid collision and scraping of curb plate and tire and damage each other to provide track spare and follow the wheel dynamics of turning to.

The main gear arranged outside the side plate is driven by the gear of the driving wheel B outside the side plate.

Connecting and adjusting bars for connecting the front and rear track pieces: the distance between the front and rear track pieces is connected and adjusted, and the length can be manually adjusted; the two ends of the crawler are buckled in the left and right splayed one-way tooth grooves, and when the vehicle sunken crawler contacts the ground and compresses the distance between the left and right crawler members, the crawler members automatically fall to lock the distance, and the working state of the crawler is automatically adjusted. Is disposed only on one side of the wheel outer side plate. Inconvenient installation and adjustment of the inner side of the wheel

Install at the vehicle bottom prevent the scraper blade with install on crawler spare upper portion prevent scraping universal pulley: the single side of the crawler belt piece is prevented from being forced upwards to touch the bottom of the scraper rigid, and the tire and the crawler belt piece are kept to have a normal steering function.

The lower swing arm hanging and rotating frame at the inner side of the tire: preventing inboard disengagement from the tire and providing integral steering capability.
