One, will the reset rope sling (37) of steel wire tow line (36) front end is enclosed within on the stay cord hanging column (33) that resets at brake control lever (6) middle part, steel wire tow line is upwards walked around the top of the pulley that resets (34), the tail end of steel wire tow line is placed the automobile rear, firmly pull back the tail end of the steel wire tow line that resets (36), make brake control lever overcome extension spring (32) and rotate to anticlockwise direction (front upper place) to clockwise pulling force.Up-narrow and down-wide right angle trigonometry body (12) on being located at arcuation slipper (11) moves upward and when contacting the oblique head of banking pin (17), just oppresses banking pin (17) it is slided to caudal directions.When whole up-narrow and down-wide right angle trigonometry body (12) moved to the top of banking pin (17) fully, banking pin (17) just under the pressure effect of compression spring (19), slided to the banking pin cephalad direction, and withstood on the front of arcuation slipper (11).At this moment, the resistance shelves that brake control lever (6) front has been subjected to revolving limited post (5) before the brake control lever are and out of service, and this just makes brake control lever (6) rest on this position.At this moment, we just take off steel wire tow line (36) from the stay cord hanging column (33) that resets that is entangled by it, be stored in the tool box.This just makes brake control lever (6) change into rest (lifting) state, (seeing Figure of description 11) by work (friction) state.At this moment, the direction that the front end of brake control lever (6) stretches to vehicle front (41), and brake drum (57) also has a very big segment distance apart from vehicle front.The top of brake drum is near below the automobile longitudinal girder, and the bottom of brake drum also is higher than the bottom of the forward and backward vehicle bridge of automobile.The outward extending width of brake drum is above outward extending width at the bottom of the truck body.The bottom of the mainboard (1) of vehicle hedging drg is higher than the bottom of the forward and backward vehicle bridge of automobile.Therefore, be installed on vehicle hedging drg on the automobile after, can not cause a bit influence to the appearance and modeling and the driving safety of automobile.At this moment, remove the pad car plank of pad four wheel bottoms, this automobile just can be set out on a journey and travelled.
Run into the method for operation must sudden stop the time when two, travelling: when automobile travels on highway, as run into ice-bound road surface, when automobile will be gone out highway because of breakking away, or when preventing that bumping against emergent pedestrian needs sudden stop, or damper brake is operated when out of control on down-hill hill path, all need sudden stop, to prevent the generation of serious accident.At this moment, the driver can hold bearing circle with a palm, (backguy lock folder also can be fixed on the bearing circle to chew the upper handle of two the backguy locks folders (21) on the lower lip support (45) with near the duck of a finger presses being located at once, also two backguy lock folders can be merged into a backguy lock folder), make upper handle (25) near lower handle (26).Under the combined action of online skin (20) and wire (23), make two banking pins (17) overcome the pressure of compression spring (19) and to caudal directions operation, its head just leaves arcuation slipper (11) one segment distances.After up-narrow and down-wide right angle trigonometry body (12) has been broken away from the control of banking pin (17), brake control lever (6) is rotated downwards, and make brake drum (57) and grab ground projection (8) front end lunge ground, along with advancing at utmost speed of automobile, brake control lever (6) enters when revolving spacing U type groove (4) behind the brake control lever, just stop to move backward, at this moment, the gravity of automobile rear can make below the brake drum and road (ice) face closed contact, owing to all be uniform-distribution with numerous ground projections (8) of grabbing around each brake drum, kiss the earth grab the ground projection can thrust ice () face, also just increased the adhesive ability between ground and the brake drum greatly.Along with advancing of automobile, be located at just rotation in a clockwise direction of brake drum on the automobile right-hand stringer (be located on the automobile left-hand stringer brake drum with anti-clockwise rotation).The automobile application force that produces that advances is forwards, and the gravity of automobile rear is downwards, and therefore, the friction lining that is on the fixedly brake shoe brake cheek (52) of front lower place can produce powerful friction force with the brake drum inwall; Friction lining on the movable brake shoe brake cheek (54) that is supported by compression spring (55) also can produce certain friction drag with the brake drum inwall.Simultaneously, since on the brake drum grab ground projection (8) thrust ice () face, also just make the far-end of the cam position adjusting arm (62) that is located at the brake drum side be subjected to the compressing that ground makes progress, make its drive camshaft (59) and cam (60) to right-hand revolution, make the clinohedral (61) of the extruding activity brake shoe brake cheek bottom, top of cam, make by force movable brake shoe brake cheek and fixedly brake shoe brake cheek separate to both sides, make the friction lining (56) that is located at their peripheries tightly oppress the inwall of brake drum (57), this has just produced huge friction force, therefore, can produce very big braking force to the automobile that advances at utmost speed, this just can make automobile shorten the distance that slides forward greatly after implementing emergency braking.
Because the anti-sideslip ability of used general-utility car tire is not so good, especially on ice-bound road surface, turn round because of road sometimes or turn round owing to overtaking other vehicles, when the speed of a motor vehicle is higher, tend to great traffic accident take place because of sideslip.For reducing the generation of skidding accident, this vehicle hedging drg has been installed coupking shaft (47) at the far-end of its brake control lever (6), it pierces in the universal axle sleeve (48), universal axle sleeve (48) can rotate around coupking shaft (47), because after brake control lever (6) becomes hang by the state of lifting, its coupking shaft (47) that is located at the brake control lever lower end is perpendicular to the ground, therefore, universal axle sleeve can it connects in tow (51) rotation flexibly of cranking arm, make brake drum (57) be in the rear of coupking shaft (47) all the time.Therefore, no matter automobile advances or breaks away, the braking force that brake drum produces, the direction of moving facing to car body (just comprising that also the direction of breakking away takes place automobile) all the time.Therefore, use this vehicle hedging drg, not only can make the distance of the automobile shortening ahead running that advances at utmost speed, also can reduce the incidence of skid accident.Because a vehicle hedging drg has respectively been installed on the right side of automobile left side and automobile, and grabbing on their brake drum specification, the quantity of projection (8) all be consistent, and the time that begins to rub, front and back position also are identical; Be in the compression spring (49) of universal axle sleeve (48) top, can produce certain buffer action, as run into when the road surface of the left and right sides is uneven under the wheel, two brake drums (57) all the time can both ground proximity about it can make, and the friction drag that produces also is essentially identical, so just can not make the automobile sideslip direction of advancing.
On an automobile, when needing emergency braking, using two vehicle hedging drgs to add the driver brakes jointly with the pedal brake lock, its braking effect can be than depending merely on driver effective many with pedal brake lock braking, the distance of operation shortens greatly before can making automobile after implementing emergency braking, this just can be avoided automobile to bump against emergent pedestrian on the road, can avoid automobile to fall the steep cliff in roadside because of ice and snow breaks away, can reduce greatly because of the unexpected heavy damage of causing for automobile and driver and conductor of driving a vehicle, can improve the safety coefficient of running car.
Three, when automotive use vehicle hedging drg braking and after halting, brake control lever (6) is in work (friction) state, grab ground projection (8) and lunge ice face (seeing Figure of description 13) and need in time brake control lever (6) to be changed into rest (lifting) state by work (friction) state, so that automobile continues to travel.Method of operation is as follows: automobile is fallen back backward, make the ice face that ground projection (8) breaks away from its insertion of grabbing.In the tool box, take out the steel wire tow line (36) that resets then, rope sling (37) is entangled the stay cord hanging column (33) that resets that is located at automobile right side P type mainboard vehicle hedging drg (44), after steel wire tow line (36) upwards walked around pulley (34), its rear end is placed automobile rear.Pull back the afterbody of the steel wire tow line that resets (36).Up-narrow and down-wide right angle trigonometry body on being located at arcuation slipper (11) promotes banking pin (17) and when moving to its top, this just makes the brake control lever (6) of P type mainboard vehicle hedging drg (44) change into rest (lifting) state (seeing Figure of description 11,12) by work (friction) state to caudal directions.Use the same method again the brake control lever (6) that is located at the q type mainboard vehicle hedging drg (43) on the automobile left-hand stringer (39) is changed into rest (lifting) state by work (friction) state.After all finishing, automobile just can continue to travel.
Here need to prove, when automobile normal running, the brake control lever (6) of vehicle hedging drg is in rest (lifting) state, when the needs sudden stop, the driver as long as press the upper handle of two backguy lock folders (21) arranged side by side simultaneously, just can make the brake control lever (6) of two vehicle hedging drgs change into work (friction) state by (lifting) state of rest in moment with a hand simultaneously.When its brake control lever (6) being changed into rest (lifting) state by work (friction) state, then need to carry out respectively singly as need.
Automobile is when travels down, in most of the cases do not need to use vehicle hedging drg to brake, only on ice-bound road surface, or on road surface wet and slippery behind the rain, under extremely critical situation, the driver thinks only can not implement glancing impact effectively by the pedal brake lock in limited distance, just can when adopt the pedal car damper brake, increase and use vehicle hedging drg to brake.Automobile uses vehicle hedging drg to brake being covered with on the highway of frost, and the ground projection (8) of grabbing on the brake control lever does not reach highway pavement, can not cause damage to the road surface.If desired during emergency braking, grab ground projection (8) and may cause some simple cuts to the road surface on the road surface of anti-freezing, these simple cuts generally do not need to repair.Repair as need, only need be coated with a upper strata pitch and get final product, required service expenditure seldom, this expense and can not in limited distance, implement to brake effectively because of automobile, and the loss of the car crash that causes is compared, then insignificant.Use vehicle hedging drg, can significantly reduce the generation of traffic accident, can save the expenditure that motor insurance company is used for the traffic accident insurance indemnity greatly, very big benefit is all arranged in state in the people.
According to actual needs, when the brake control lever (6) of vehicle hedging drg is changed into rest (lifting) state by work (friction) state, can change into by hydraulic pressure or pneumatic compression devices and implementing; When brake control lever (6) is changed into work (friction) state by (lifting) state of rest, can implement by electromagnet or electrical motor.
