Description
Technical field
The present invention relates to a kind of brake gear, brake cable fracture safe emergency auto braking device when especially relating to a kind of brake of electric vehicle.
Background technology
Brake gear produces friction by between brake facing and wheel hub or disc, and a kind of device that kinetic energy when being travelled by car body in the process rubbed becomes thermal energy consumption to fall.
Along with the development of society, the consciousness of people to environmental protection is also more and more paid attention to, battery-driven car starts the trip instrument becoming more and more people, it has that noise is little, environmental protection, the advantage such as easy to use, the brake gear of present battery-driven car is all adopt parking brake, when excessive velocities needs sudden stop, very easily causes brake cable to rupture in brake process, so just there is very big potential safety hazard, constrain further developing of battery-driven car.Now brake cable generally commercially is medium-carbon steel steel wire multiply and twists into, getting rusty in addition after multi-drawing, the as easy as rolling off a log fracture of steel wire, and most crack conditions all occurs in emergency situation overexerts instantaneously, to such an extent as to steel rope breaking, in this case the accident that fracture often causes brake failure and then occurs in various degree, is embedded with great potential safety hazard to our life security.
Present at battery-driven car universal and Frequent Accidents; battery-driven car seems safely particularly important; compare with automobile; under the protection lacking steel shell; hour of danger brake measure just seems particularly important, and the safety and reliability improving a brake measure technical barrier in the urgent need to address especially.
Summary of the invention
In order to overcome the deficiencies in the prior art, brake cable fracture safe emergency auto braking device when the invention provides a kind of brake of electric vehicle.
Brake cable fracture safe emergency auto braking device during a kind of brake of electric vehicle, described device comprises feedback mechanism, actuating unit and trailer coupling, described feedback mechanism comprises lever, extension spring, slide rail and the slide block matched with slide rail, described slide block is connected with lever by connecting panel, described connecting panel is fixedly installed on slide block, described lever lower end is connected with lever brake cable contiguous block, lever upper end is connected with extension spring and connecting panel respectively by connection lead, described extension spring one end is connected with lever by connection lead, the other end is fixed on extension spring adapter plate, described lever is arranged on lever dolly, lever length and total lever length of described lever dolly upper end are in a ratio of 2 ~ 3:4,
Described actuating unit comprises pulley, stage clip and stage clip baffle plate, described pulley is arranged on pulley support, described pulley support is fixedly installed on bearing adapter plate, described stage clip is arranged in sleeve, described sleeve is arranged on sleeve adapter plate, described sleeve adapter plate is positioned at above pulley, and described stage clip baffle plate to be arranged on above sleeve and to be positioned at below slide block;
Described trailer coupling comprises the twine be connected with brake cable, wherein a strand exports adapter plate through first brake line outer tube, first end cover, brake cable input adapter plate, lever brake cable contiguous block and brake cable successively, and another strand is connected with stage clip baffle plate by the second brake cable outer tube, the second end cover, brake cable input adapter plate, pulley successively.
Preferably, the lever length of described lever dolly upper end and total lever length are in a ratio of 3:4.
Preferably, described sleeve is arranged on sleeve adapter plate by flange.
Preferably, described connection lead adopts flexible wire ropes.Due between lever and connecting panel and extension spring for flexibly connecting, have and pulling force can only be provided to produce thrust, make device avoid when normal braking produce response.
Because brake cable fracture very likely occurs in the emergency state, under brake weight larger in a flash, cause brake cable to rupture, cause brake failure, cause accident.The present invention can realize trailing wheel emergency braking in the moment of brake cable fracture, and utilize pure physical construction, have that structure is simple, safety good, reliability is high, with low cost, can the advantage such as promoted extension is wide, the vehicle that the present invention is applicable to bicycle, battery-driven car and motor bike etc. that speed is larger need brake cable, its safety factor can be improved, effectively avoid the generation of accident.
