Abstract

The invention discloses an emergency brake device which comprises accessories, such as an electromagnetic switch arranged in a cab, a rear wheel braking lever, a steel wire rope, an electromagnetic pushing and absorbing element, and the like. After the current is switched on, the rear wheel braking lever is instantly contacted with and separated from a rear wheel tire under the electromagnetic pushing and absorbing action and the rear wheel braking lever is driven to rotate by the natural rolling force of the tire, thereby achieving the purposes of preventing the tire from rolling forward within a short period of time and braking a vehicle. The emergency brake device is suitable for a big-tonnage truck and can be assembled under the condition of maintaining the original structure of the truck.

Description

Emergency brake

The present invention relates to a kind of emergency brake, is a kind of emergency brake brake gear that relates to automobile specifically.

Current automobile has become the main vehicle that people's transportation is ridden instead of walk, and various model automobiles are more and more, and dead-weight capacity is increasing, and vehicle speed is more and more faster, and serious accident frequently takes place, and reduce the serious accident generation is the thing of traffic control department concern always.By retrieval and do not find the emergency brake similar to this case.

The object of the invention provides a kind of emergency brake brake gear that is used for large-scale autotruck.When full-sized car or other lilliput car under the former braking brake malfunction or the situation of braking brake quantity not sufficient, this device can play the purpose that automobile is stopped in the auxiliary braking brake at short notice.

Realize by following proposal for achieving the above object, be embodied as now known DC electromagnet and push away adsorption technology, in operator's compartment, establish electro-magnet switch or lead, outside operator's compartment above the chassis back wheels of vehicle tire back, a hollow slideway is respectively established in crossbeam bottom, the left and right sides, make moving brake horizontal lever in the slideway, braking brake horizontal lever two and back wheels of vehicle tire contact position, if roll cover or skidproof whippletree or rhombogen, respectively establish two steel rope capstan winches about braking brake horizontal lever both sides, establish steel rope in the capstan winch, steel rope is chosen iron with former car braking brake cam and is connected, be connected and fixed on steel rope and the car carrier housing in another capstan winch, the braking brake horizontal lever is made as monolithic devices or single build.Monolithic devices is an Oversize vehicle usefulness, single build be compact car with or Oversize vehicle also can use.Described before brake linkage or crossbeam bottom, the left and right sides, back respectively establish electromagnet and push away the suction body, be connected with storage battery, driving cubicle switch by lead, the flexible contact place of electromagnet armature establishes slip joint or dust protecting cap, establishes antifriction-bearing box with braking brake horizontal lever junction.The described displacing force that pushes away with inhale that utilizes electromagnet makes the braking brake horizontal lever with the contact of back wheels of vehicle tire or separate, and reaches workmanship's purpose.In this case, some known technologies or parts are no longer carefully stated.

It is described: after workmanship is making current, electromagnet pushes away the braking brake horizontal lever or suction contacts with the back wheels of vehicle tire, utilize the natural rolling power of vehicle tyre to drive the rotation of braking brake horizontal lever, the brake horizontal lever rotates or rolls, the interior steel rope of the capstan winch of having reeled, steel rope has spurred former car braking brake cam and has chosen iron, former car brake rubber block and brake wheel friction drag are strengthened, in another capstan winch wire rope roll around, strained the contact distance of braking brake horizontal lever with vehicle tyre, two pull of steel wire have strengthened the friction drag of vehicle tyre and braking brake horizontal lever, and former car braking brake skin of while or brake wheel are because pull of steel wire has also strengthened friction drag.Braking brake horizontal lever rotating speed is fast more, two pull of steel wire are big more, the resistance of braking brake is also big more, vehicle tyre back on the other hand, just in time an angle between vehicle tyre and the crossbeam, the braking brake horizontal lever is just between this angle because the power of supporting of two pull of steel wire, crossbeam, braking brake horizontal lever can not roll vehicle tyre is stuck, more than the resistance of three aspects reach the purpose that car brakeing is stopped.Described; Skidproof whippletree or rhombogen are established in braking brake horizontal lever two and vehicle tyre contact position.Because it is stressed that vehicle tyre and braking brake lever are that rollability contacts, friction drag changes from weak to strong, and car brakeing is stopped can not causing damage.Should the polyembryony heavy-duty vehicle also can be installed additional by joint group the sudden stop device.

Modern design of the present invention, simple and reasonable does not change primary car structure, installs additional conveniently, can not increase expensive, processing ease, the emergency brake braking quality is better, the repeated multiple times that can link up is used, and has practical applied value.
