Description
[technical field]
The utility model relates to a kind of brake gear, and particularly a kind of tire that protects of vehicle is assisted emergency brake device.
[background technology]
While there is emergency situation in Vehicle Driving Cycle process, people wish that vehicle can stop in compared with short range, but under high-speed case, conventionally, because the positive pressure on vehicle and ground is inadequate, make friction force inadequate, can not stop fast.Emergency brake is by external force, tire to be embraced, and relies on the friction force on tire and ground to brake; But vehicle emergency brake rear tyre is easily worn into irregular type, if old tire when long brake easily because galling explosion, and mill tire phenomenon while also avoiding emergency brake without special technology at present; Also having in addition a kind of situation is that Vehicle Driving Cycle skids and loses braking force to ice face Chang Yin, and preventing from present skidding is with nonskid chain; But nonskid chain, for Vehicle Driving Cycle designs on ice face, is not suitable for ordinary road, and the Assembly &Disassembly of anti-slipping chain is pretty troublesome.
Application number is 99235929.5, the Chinese patent that the applying date is 1999-05-05 provides a kind of automobile safety braking device, it mainly consists of brake frame and rim strip two parts, brake frame is arranged on the crossbeam of automobile both sides, there is one group to control the device that rim strip puts down or mentions, when wanting sudden stop, rim strip 1 is put down and is applied on road surface, allow the wheel of rotation at full speed enter on rim strip, by rim strip, supporting automobile and braking with pavement friction.This brake gear has emergency brake effect, can avoid because of the uneven vehicle shift phenomenon causing of brake weight and can effectively protect motor tire.But it has following shortcoming:
1, rim strip is that tiling is placed when not working, and by spring, keeps fixing, and because the effective working distance of rim strip has certain length, required spring also will have corresponding length, and its occupation of land is too large, is difficult to practical application on vehicle;
2, it is controlled as rope form tractive, and because the longer tool of its distance is flexible, both sides are difficult to accomplish synchronization action, are not only not easy to accomplish that brake weight is even, on the contrary likely because both sides rim strip can not enter under wheel simultaneously, produce and break away.
3, its rim strip is for vertically discharging, and actual chaufeur is stepped on after brake, may embrace wheel, and wheel and ground are to slide rather than roll, and rim strip is likely promoted before wheel and can not enter smoothly below wheel like this.
4,, outside brake is directly exposed to, is easily covered with dust and waits foreign material impact use.
Application number is 99254962.0, the applying date is that the China of 1999-12-10 discloses a kind of pad wheel type emergency braking pad for automobile, it comprises shell and electrical motor, shell is arranged on wheel guard shield, feature is that steel rope stationary roll is installed on motor reel, steel rope is fixed between steel rope stationary roll and brake lining, is processed with skin tooth on bottom surface.Between steel rope, be fixed with cross bar, on shell, be processed with the spring groove of placing spring.This brake lining has increased wipe contact area and the resistance on self-propelled vehicle and ground, is equivalent to put on antiskid shoe to self-propelled vehicle, can in shortest distance, check car, and self-propelled vehicle and personnel can be effectively protected.But it has following shortcoming:
1, the electrical motor of its design is the rear that is positioned on brake lining, the part that brake lining is connected with motor is flexible article, the propulsive effort of motor can not directly drive brake lining, during use, be to loosen the constraint of brake lining to hold deadweight landing by brake, this process easily causes dislocation because of the reasons such as vibrations of driving, affects the landing of brake lining.
2, its brake lining is plane block, if wheel is rolling condition, be can enter smoothly wheel below to play a role, but when chaufeur is stepped on after brake, may embrace wheel, wheel and ground are to slide rather than roll, rim strip is likely promoted before wheel and can not be entered smoothly below wheel like this, causes reliability poor.
[utility model content]
The technical problems to be solved in the utility model, is to provide a kind of tire that protects of vehicle to assist emergency brake device, stable performance, and braking is reliable, easy to operate.
The utility model can be realized like this: a kind of tire that protects of vehicle is assisted emergency brake device, comprise cavity, protect tyre shoe, bolster, overriding clutch, transmission shaft, motor and flip flop equipment, describedly protect tyre shoe and bolster is located in cavity, and protecting tyre shoe is wrapped on described bolster, and one end is fixed on bolster, the other end is free end, described bolster is connected in described bolster by described overriding clutch, this transmission shaft is rotated by described driven by motor, and described motor triggers running by described flip flop equipment.
Further, described in to protect tyre shoe be the camber structure that flexible material forms, be more conducive to enter under wheel.What pliability referred to is exactly neither too hard, nor too soft, in the situation that not being subject to external force, can form more fixing shape, and has certain elasticity, can flexural deformation in the situation that is subject to external force, and between rigidity and tenderness.
Further, described in protect tyre shoe free end on that surface of tire, be also provided with end nail dorsad, be conducive to stop in ice face speed.
Further, described cavity is the casing of being located in the vehicle body of wheel the place ahead, this casing is connected on described bolster by bearing, and this casing tiltedly below has one for the described opening that protects tyre shoe turnover, use casing can avoid protecting tyre shoe contaminated, described in being used for, protect the opening of tyre shoe turnover and be located at the oblique below of casing, be beneficial to and protect tyre shoe and take out of smoothly.
Further, the brake system that described flip flop equipment is vehicle, interlock is convenient.
The utlity model has following advantage: the auxiliary emergency brake device of tire that protects of the utility model vehicle directly drives and protects tyre shoe with the propulsive effort of electrical motor, and holding up tyre shoe is neither too hard, nor too soft camber structure, under the drive of motor, itself have to the trend of moving below wheel, easily enter under wheel, stable performance, braking is reliable, easy to operate, is suitable for new Design vehicle.The utility model will protect tyre shoe and hunch, can reduce take up space, be beneficial to various vehicles and install.
[accompanying drawing explanation]
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the installing condition structural representation that the utility model protects the auxiliary emergency brake device of tire.
Fig. 2 is the inner side structural representation that the utility model protects the auxiliary emergency brake device of tire.
