Abstract

The invention belongs to the technical field of vehicle safety facility design manufacturing, and relates to an intelligent-type ice and snow area automobile auxiliary braking device, in particular to an automobile anti-skidding device which instructs an anti-skidding motion by means of an ABS signal. The intelligent-type ice and snow area automobile auxiliary braking device is composed of a braking system and a servo system. A plurality of radial through holes are formed in spokes of an anti-skidding wheel of the braking system. Pins which are in clearance fit are arranged inside the radial through holes. The pins are sleeved with springs. A single-output rod of a hydraulic cylinder in the servo system is connected with a rotating shaft of a pressing wheel through a bearing. The radial section of the pressing wheel and the axial sections of the pins are located inside the same plane. When the single-output rod in the hydraulic cylinder extends out, the pressing wheel and the inner ends of the pins form extrusion contact. According to the intelligent-type ice and snow area automobile auxiliary braking device, the anti-skidding wheel is arranged on the inner side of an automotive rim, the ABS is utilized for controlling the pressing wheel to move up and down through an electromagnetic directional valve, and the anti-skidding pins are extruded and pushed to be embedded into an ice surface of a snowfield to achieve the anti-skidding aim. Therefore, the intelligent-type ice and snow area automobile auxiliary braking device has the advantages of being high in intelligentized degree, good in flexibility, high in adaptability, free of influences on appearance, high in safety coefficient and the like.

Description

Intellectual ice-snow field auxiliary brake device for automobile

Technical field

The present invention relates to a kind of ice-snow field auxiliary brake device for automobile, particularly a kind of anti-slip device for automobile that utilizes ABS signal instruction antiskid action belongs to Machine Manufacturing Technology.

Background technology

The car skidding problem of travelling at snowfield ice face, that people pay close attention to and study and end the difficult problem that the present still can not effectively solve always, people once taked various measures for these years, as bundling anti-slipping chain at tire, inlay anti-slop serrations, be provided with the metal skid-proof shell of dentation in the outside of tire, adopt cushion block to land suchlike methods such as stopping the wheel slip, make every effort to find the measure of a kind of practicable automobile preventing skid on snow, it should be sure that: these methods and measure hold water theoretically, also has certain skidproof effect in actual the use, but these methods have different shortcoming and defect with measure, such as: bundle anti-slipping chain at tire, inlaying anti-slop serrations easily makes motor tire damage, its structure of other certain methods and measure is too complicated again, when running into interruption snowfield ice face, the special specific aim that lacks, effect was inadequate when the formation needs were anti-skidding, do not need not only to affect when anti-skidding the overall appearance of automobile, it is burdensome unnecessary also to feel very much under steam.Therefore, solve the anti-skidding problem of vehicle skidproof problem, particularly Intelligent control automobile under the snowfield ice noodles spare, be worth probing boldly further and studying.

Summary of the invention

The object of the invention is to propose a kind of intellectual ice-snow field auxiliary brake device for automobile, utilize ABS antiblock device signal, the work of instruction complemental brake system, thus reach intelligent control auxiliary braking purpose.

To achieve these goals, Bian of the present invention gets following technical scheme and implements: it is comprised of brake system and follow-up system, brake system comprises: anti sliding wheel, pin, spring, bolt, follow-up system comprises pinch roller, hydraulic actuating cylinder, solenoid directional control valve, bearing, anti sliding wheel in the brake system is arranged on a side of automobile wheel rim, be provided with several radial direction through hole in the anti sliding wheel spoke, be provided with the pin of free-running fit in the radial direction through hole; Single rod of hydraulic actuating cylinder is connected with the rotating shaft of pinch roller by bearing in the follow-up system; The radial section of described pinch roller and the axial cross section of pin are positioned at same plane; Described pinch roller forms extruding with the inner of pin and contacts when the single rod in the hydraulic actuating cylinder stretches out; The outer end of described pin is free end; Cover has spring on the described pin.

The anti sliding wheel inboard can arrange a circumferential circular groove that is recessed to dish among the present invention, and the rear end head of pin can arrange a step.Pinch roller thickness in the follow-up system is less than described circumferential annular well width; The cylinder body of hydraulic actuating cylinder is fixedly connected on the sole of automobile; Solenoid directional control valve can be designed to two-position three way, and the piston that the piston rear end of energising in the hydraulic actuating cylinder communicates, cuts off the power supply with hydraulic oil in the hydraulic actuating cylinder resets under the front springs effect, and the hydraulic oil of piston rear end communicates with fuel tank; Anti sliding wheel can be made one with automotive rim; Pin rear end cover has spring, has guaranteed resetting of pin; The energising of solenoid directional control valve or outage are controlled by ABS antiblock device information in the follow-up system.

The present invention arranges anti sliding wheel in the inboard of automotive rim, and the skidding signal instruction two position, three-way electromagnetic change valve that detects by ABS system energising, hydraulic oil communicates with piston rear end in the hydraulic actuating cylinder, extension bar promotes pinch roller and does upper and lower motion, the crowded anti-skidding pin that pushes away the anti sliding wheel bottom of wheel rim of pinch roller is stretched out outside the anti sliding wheel, thereby realize that pin embeds the anti-skidding effect of snowfield ice face, cross the wheel rim of pinch roller when pin after, pin automatically retracts to anti sliding wheel inside under the elastic force effect of spring.Compare with traditional vehicle skidproof technology, useful contribution of the present invention is: 1. anti-skid device is subjected to the ABS signal control, has realized intellectuality; 2. when the needs complemental brake system was worked, pinch roller promoted pin and stretches out, when not needing complemental brake system work, and the indentation of spring compressing pin, so alerting ability is good, strong adaptability, and harder urban pavement is not caused damage; 3. anti sliding wheel is arranged on the inner side plane of automotive rim, does not affect outward appearance; In case 4. tyre break in the Vehicle Driving Cycle process because the anti sliding wheel diameter is slightly less than the vehicle tyre diameter, so the anti sliding wheel that is wrapped in rubber ring can be used as the wheel Emergency use, is unlikely to make automobile steering out of control, greatly increased the safety factor of driving.
