Description

Intellectual ice-snow field auxiliary brake device for automobile

Technical field

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

Background technology

The traveling automobile problem of skidding on snowfield ice face; Be that people pay close attention to and study and end the modern difficult problem that still can not effectively solve, people once taked various measures for these years always, as on tire, bundle anti-slipping chain, inlay anti-slop serrations, be provided with in the outside of tire dentation the anti-slip case of metal, 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; Should affirm: these methods and measure hold water theoretically, also have certain skidproof effect in actual the use, but these methods all have different shortcoming and defect with measure; Such as: on tire, bundle anti-slipping chain, inlay anti-slop serrations and be prone to make motor tire to damage; Its structure of other certain methods and measure is too complicated again, when running into when being interrupted snowfield ice face, lacks specific aim especially; Formation needs effect when anti-skidding inadequately, not need not only to influence when anti-skidding the overall appearance of automobile, and it is burdensome unnecessary also to feel very much under steam.Therefore, solve the anti-skidding problem of vehicle skidproof problem, particularly Based Intelligent Control automobile under the snowfield ice noodles spare, be worth probing boldly further and studying.

Summary of the invention

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

To achieve the above object, the present utility model posed to the implementation of the following technical solution: it is the brake system and the servo system composed of the brake system comprises: Anti pulleys, pins, springs, bolts, with the dynamic system includes a pressure roller, hydraulic cylinders, solenoid valve, bearing, the brake system of the car against the pulley disposed on one side of the rim, against the pulley is provided with a plurality of spokes radial through holes in a radial through-hole gap with the pin; with moving system single rod of the hydraulic cylinder and the pressure by a bearing shaft connected to the wheels; said pressure wheel radial section and an axial section of the pin in the same plane; said pressure wheel and the inner end of the pin when the hydraulic cylinder The single rod extends a squeeze contacts; said pin outer end is a free end; said pin on the sets of a spring.

The anti sliding wheel inboard can be provided with a circumferential circular groove that is recessed to dish in the utility model, and the rear end head of pin can be provided with a step.Pinch roller thickness in the follow-up system is less than said 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 processed one with automotive rim; The pin rear end is with spring, has guaranteed resetting of pin; The energising of solenoid directional control valve or outage receive ABS antiblock device information Control in the follow-up system.

The utility model is provided with anti sliding wheel in the inboard of automotive rim; And through the detected skidding signal instruction two-position three way solenoid directional control valve energising of ABS system; 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.With traditional vehicle skidproof compared with techniques, the useful contribution of the utility model is: 1. anti-skid device receives 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, comformability is strong, and harder urban pavement is not caused damage; 3. anti sliding wheel is arranged on the inner side plane of automotive rim, does not influence outward appearance; In case 4. tyre break in the vehicle ' process is 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 emergent use of wheel, is unlikely to make automobile steering out of control, has greatly increased the safety factor of driving.
