Abstract
The utility model relates to an automotive semi-caterpillar anti-skid device, which is composed of an integral type rubber, tension wheels, a pneumatic support cylinder, and a tensioning cylinder. The upper ends of the two cylinders are respectively arranged on the longitudinal beam of the front frame of the driving wheel, and lower ends are mutually hinged. The tension wheels are arranged on the crank shaft on the lower end of the support cylinder and can be contracted and hung below the automobile frame without use. When the automobile meets road with ice and snow, the rubber belt track is sheathed on the driving wheel and the tension wheel and the driving wheel and the tension wheel are tensioned. The automobile wheeled type running device is quickly changed into a semi-caterpillar running device. The utility model can improve the through capacity and safety of the automobile, do not damage road surface, and do not increase the running noise. The structure of the original automobile can not be changed.
Description
The utility model belongs to the device that improves the automobile pass ability energy
When automobile travelled on accumulated snow or icing road surface, because coefficient of road adhesion descends, adhesion value was relatively poor, makes the rideability of automobile be subjected to very big influence, even can't cruising, and safety traffic and transportation are difficult to guarantee.
Improving at present the rideability of automobile on the ice and snow road, mainly is to adopt edge nail wheel, or on drive wheel the suit anti-slipping chain.
Adopt edge nail wheel, skidproof effect is preferably arranged, but cement, asphalt surface are had damage, tire weak point in service life, dismounting inconvenience.Suit anti-slipping chain on drive wheel, though simple and easy to do, Running noise is big, cement, asphalt surface are had damage, and skidproof effect is not ideal enough.
The purpose of this utility model, the damage that is to improve the enforcement performance of automobile on ice and snow road He prevents road pavement.And do not increase the Running noise of automobile.
Half-track anti-skid device of the present utility model is by integral rubber---and steel wire crawler belt, tension wheel, pneumatic type supporting cylinder barrel and tensioning cylinder barrel etc. are formed.Rubber---steel wire internal track surfaces vertically symmetry, in be provided with the joint tooth in the heart, its effect is to prevent that drive wheel and bogie wheel from laterally deviating from.Tooth depth and pitch are determined by the bogie wheel radius that mainly transverse tooth thickness is mainly determined by the horizontal section physical dimension of two drive wheels arranged side by side.Inside face joint tooth causes outer rim an inclination angle, to improve inside face from property tied and drainage ability.Crawler belt outside face, transversal surface are two arcuate surfaces, longitudinally have the bigger snakelike decorative pattern of several grooves and and lateral trench be communicated with, make it the stronger performance of squeezing snow, water, raising is adhered to and is surrounded by steel wire floor in the crawler belt with raising crawler belt pulling force ability.
Tension wheel adopts two-wheel arranged side by side, its athwartship plane scantling of structure and former car drive wheel basically identical, and it mainly act as seizes crawler belt on both sides by the arms, prevents that crawler belt from laterally deviating from, and plays the tensioning and the directional tagging of crawler belt.The tension wheel diameter is by installation site and the decision of former car road clearance, and diameter is too small will to influence the crawler belt life-span.
Tension wheel is installed in the lower end of pneumatic supporting cylinder barrel and turns on the axle, and its horizontal vertical angle is guaranteed by the supporting cylinder barrel, supporting cylinder barrel lower end and the hinge joint of tensioning cylinder barrel, and vertical angle of tension wheel is guaranteed by the tensioning cylinder barrel.Tension wheel can vertically stretch, also can longitudinally stretch.
Supporting cylinder barrel and tensioning cylinder barrel all adopt pneumatic type, make it the effect of air bellow of having held concurrently, and impact to relax.The strength source of two cylinder barrels utilizes former car brake system Air Force source.Supporting cylinder barrel air pressure is by the support reaction decision of hanging down of tension wheel ground, generally gets the 20%-30% of load on axle journals (be fully loaded with) behind the former car, and the air pressure of tensioning cylinder barrel is determined by the pre-tensioning of crawler belt.
The utility model has the advantages that and adopt the half-track anti-skid device, the part of the decorative pattern projection of crawler belt appearance face width, deep trench (carrying out thorn) is when ground connection, make decorative pattern that higher unit pressure be arranged over the ground, crowded the opening directly of ice and snow layer contacted with road surface, the hard end, improved " grabbing ground " ability.Simultaneously track area increases than the ground contact area of former car drive wheel adhesion value is improved, the maximum driving force (on ice snow covered pavement) that is produced according to the pertinent data rough calculation when being unkitted anti-skid device about 3.2 times, and the maximum ground braking force is 1.6 times.
The half-track anti-skid device is set, needn't makes big change primary car structure.When entering winter, to support cylinder barrel in advance, the tensioning cylinder barrel, tension wheel installs, air-pressure duct is connected with former car strength source with control cock and tension wheel is locked on the vehicle frame, when running into ice and snow weather or road, can promptly former wheel formula running gear be changed into and partly fulfil walking apparatus and improve the driveability of automobile on the ice and snow road, simultaneously do not damage the road surface, do not increase Running noise.Crawler belt mounting or dismounting wheel is convenient.The supporting cylinder barrel of this device and tensioning cylinder barrel are to utilize former car brake system air source this makes designs simplification for power.
Narrate embodiment below in conjunction with accompanying drawing:
Accompanying drawing is the half-track anti-skid device at former bus equipment, mainly form, and on chassis side rail, install axle (6) and the axle (7) that is used for mounting support cylinder barrel and tensioning cylinder barrel by tension wheel (1), supporting cylinder barrel (2), tensioning cylinder barrel (3), rubber one steel wire crawler belt parts such as (4).
A-A, B-B are internal track surfaces joint tooth cutaway view in the accompanying drawing
During enforcement, the upper end that will support cylinder barrel (2) is contained on the axle of setting up on the longeron (6), lower end and tensioning cylinder barrel (3) hinge joint.The upper end of tensioning cylinder barrel (3) is contained on the axle of setting up on the longeron (7), and air-pressure duct, control cock are connected better.Tension wheel (1) is contained in turning on the axle of supporting cylinder barrel (2) lower end, and the tension wheel rise is suspended under the vehicle frame.
When meeting ice and snow weather or ice and snow road, with drive wheel jack-up with rubber---drive wheel and tension wheel on the steel wire crawler belt encapsulation, support cylinder barrel then and tension wheel is depressed to set pressure downwards, to set pressure, handle by the strength control cock by this process with crawler tensioning for the tension wheel cylinder barrel simultaneously.
When running car, under the effect of drive torque and crawler belt predetermincd tension, the pulling force attempt that produces on the track sprocket is pulled out crawler belt under drive wheel and tension wheel, meanwhile, ground produces reverse horizontal thrust, stops crawler belt to be drawn out, and forces drive wheel to roll along crawler belt, when this ground level thrust during more than or equal to all resistance to motions of automobile, automobile promptly travels.
