Abstract
The utility model discloses a skid-proof device for the emergency brake of automobiles, which is composed of a mechanical part and a hydraulic system. A skid-proof harrow is arranged on the back upper part in the middle of the rear wheel of an automobile. A rubber plate with directional tread patterns which are in the shape of three Ys piled into a triangle is arranged. During the emergency brake of the automobile, the skid-proof harrow is in contact with the ground under the action of oil pressure, great frictional force is generated, the automobile is stopped quickly and the brake distance of the automobile is shortened greatly. Meanwhile, a hydraulic damper tensions a cylinder, a girder and a rear axle, the barycenter of the automobile lowers and the automobile is prevented from sliding and rolling. When the brake system of the automobile conks, the device can also perform the role of emergency brake and is an ideal necessary device for various vehicles.
Description
The utility model relates to a kind of anti-slip device for automobile, particularly relates to a kind of automobile emergency brake anti-skid device.
Usually emergency situation takes place as the place ahead in vehicle when running at high speed, during because of the high emergency brake of the speed of a motor vehicle because braking force is little, and car can not instantaneously stop, and will slide a segment distance, so that often have an accident, sometimes even occur breakking away and rollover phenomenon.In order to address this problem, a lot of designers endeavour this work.For example the vehicle of the CN2151055Y of Patent Office of the People's Republic of China bulletin does not have and slides instantaneous brake controller, is exactly to be the coast problem design-calculated that solves behind the automobile urgent brake car.Though it has solved the problem that slides behind the sudden stop, its complex structure uses also inconvenient.
The utility model purpose is to provide a kind of automobile emergency brake anti-skid device easy to use simple in structure, the problem that slides when it can solve the vehicle sudden stop effectively.
The purpose of this utility model is achieved in that installs an anti-skid device on the crossbeam of automobile, this device has a hydraulic accumulation energy device, hydraulic drive cylinder, hydraulic shock-absorption tension cylinder communicate with it, the upper end of hydraulic drive cylinder is connected with crossbeam, the lower end is connected with connecting rod with anti-skidding rake, the other end of connecting rod is connected with fixed mount, and fixed mount is installed on the automotive frame, and hydraulic shock-absorption tension cylinder is installed between automotive frame and the back axle.
Anti-skidding rake is equipped with the rubber plate that the bottom surface is many font directional tread patterns, and double comb shape hard metal cutter is equipped with in the area, gap of rubber plate, and an anti-skidding adjusting lever also is housed on the rubber plate.Fixed mount and automotive frame couple together triangular in shape, and the connecting rod that connects anti-skidding rake, hydraulic drive cylinder is variable triangle with hydraulic drive cylinder, fixed mount montant.
The utility model is owing to there is the anti-skidding rake of a HYDRAULIC CONTROL SYSTEM, the bottom surface of anti-skidding rake has been installed the rubber plate that is many font directional tread patterns again, therefore when automobile emergency brake, control hydraulic system can make anti-skidding rake promptly bow from subsides, and the position of back upper place falls between the two-wheeled of back, produce bigger friction force with ground, automobile is stopped rapidly, shortened braking distance, simultaneously, the pull bar of hydraulic shock-absorption tension cylinder shrinks, and tension back axle and crossbeam make it apart from shortening, centre of gravity of vehicle descends, thereby stable sideslip of automobile steering do not rolled.When on ice and snow road, travelling, can adjust double comb shape hard metal cutter in the rubber plate, can obtain satisfied skidproof effect by adjusting lever.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
Fig. 1 is the front view according to the automobile emergency brake anti-skid device that the utility model proposes;
Fig. 2 is the birds-eye view of automobile emergency brake anti-skid device;
Fig. 3 is the hydraulic schematic diagram of automobile emergency brake anti-skid device;
Fig. 4 is the local A-A cutaway view of the anti-skidding rake of automobile emergency brake anti-skid device.
Below in conjunction with details and the service condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device is made up of mechanics and hydraulic efficiency pressure system two parts.Fixed mount 15 is fixed on the automotive frame 7, triangular in shape, has stress condition preferably, one end of connecting rod 13 is connected with fixed mount 15 with hinge, the other end is connected with anti-skidding rake 9 with hydraulic drive cylinder 8 with hinge, and the other end of hydraulic drive cylinder 8 and automotive frame 7 are hinged together, and connecting rod 13, hydraulic drive cylinder 8 are formed a variable triangle with fixed mount 15, stressed good, intensity is big.Hydraulic shock-absorption tension cylinder 6 one ends are connected with automotive frame 7, and the other end is connected with automobile axle.Anti-skidding rake 9 is made up of anti-skidding adjusting lever 14, rake seat 16, rubber plate 17, knife bar 18, hard steel edge 20, spring 19.Rake seat 16 is bolted together with rubber plate 17, and there are many font directional tread patterns the bottom surface of rubber plate 17, and it is with gap hard steel edge 20 is housed, and is installed in the relative position that the anti-skidding adjusting lever of harrowing on the seat 16 can be adjusted hard metal cutter head and rubber plate 17.
Fig. 3 has provided the hydraulic work system principle of this device.Hydraulic accumulation energy device 21 is made up of fuel tank 1, hand oil pump 2, single-phase valve 3, hand change over valve 4, oil pressure control 5, compression indicator 10, pressure meter switch 11, accumulator 12.Fuel tank 1, oil pump 2, single-phase valve 3, hand change over valve connect with flexible pipe successively, oil pressure control 5 is connected with hand change over valve 4, accumulator 12, single-phase valve 3 and hand change over valve 4 usefulness flexible pipes are connected, be connected on the accumulator 12 with compression indicator 10, pressure meter switch 11 simultaneously, hydraulic shock-absorption tension cylinder 6 all links to each other with hand change over valve 4 usefulness flexible pipes with hydraulic driving oil cylinder 8.Fuel tank 1 provides enough oil masses for hydraulic efficiency pressure system, manual pump 2 can provide the high pressure oil that is not less than 10Mpa, after accumulator 12 charges into the nitrogen of 5Mpa pressure during work, hand oil pump is squeezed into high pressure oil, opens pressure meter switch 11, makes compression indicator 10 pressure reach 10Mpa, this moment, high pressure oil entered the annular chamber of driving oil cylinder 8 by hand change over valve 4, oil cylinder shrinks mentions the middle back upper place of automobile back wheel with anti-skidding rake 9, and the annular chamber and the spring cavity of damping tension cylinder 6 all communicate with fuel tank, and the damping lubricating pad is provided.During automobile emergency brake, the driver adopts urgent foot brake, pressure in the oil pressure control 5 raises, promote hand change over valve 4 commutations, this moment, accumulator 12 interior high pressure oils charged into the thrust chamber of driving oil cylinder 8 through change-over valve 4, high pressure oil also enters the pulling force chamber of damping tension cylinder 6 simultaneously, damping tension cylinder is with crossbeam and back axle tension, reduce the distance, whole vehicle rear center of gravity is descended, anti-skidding rake 9 falls ground rapidly and produces bigger friction force, vehicle is stopped fast, shortened braking distance, simultaneously because sideslip and rollover phenomenon do not appear in the decline of vehicle's center of gravity when making the vehicle emergency brake.
