Abstract
The utility model relates to a manual brake for cars, belonging to the technical field of car manual brakes, and composed of a back board assembly, a spring drag-link mechanism, two brake shoe assemblies, a gap adjusting mechanism, a return spring, a lever and a braking hub. The utility model is characterized in that one end of each brake shoe assembly clamps a wedge-shaped mechanism and a support pin. The wedge-shaped mechanism is composed of a wedge-shaped pull shaft and a pair of slide blocks. Because the utility model adopts the wedge-shaped mechanism and a two-way automatic power-assisted mechanism, the utility model has the advantages of large braking torque and equal braking torque in two directions. The utility model can ensure the safety of parking and braking of a car on a slope of 30 percent with full load.
Description
The utility model relates to a kind of lilliput car hand brake, belongs to the automobile hand brake technical field.
Existing lilliput car hand brake is two hoof internal expanding type autoamtic boosting structures.BJ130 automobile and all belong to this structure for example with the various automobiles of this chassis refit, BJ212, BJ121 automobile and with the hand brake of 50 tinkling of pieces of jade lilliput cars of the various automobiles of this chassis refit, Japan, facts have proved that for many years this structure exists the disadvantage of brake failure.In the simulated experiment data of making hand brake on the experimental bench be: automobile braking during standstill moment under the slope is more than the 1000Nm, automobile braking during standstill moment on the slope is about 170Nm, the lock torque of both direction differs greatly, automobile braking during standstill moment on the slope is too small, must slip the car phenomenon and can not effectively brake.In roadway experiment, automobile is fully loaded with the Parking of getting on the car on 20% slope on the slope car phenomenon and can not safety arrestment almost all takes place to slip, and the national people and property are subjected to the threat of safety hazard.
The purpose of this utility model provides the safe and reliable lilliput car hand brake of a kind of braking ability, and bondsman and automobile guarantee that perfectly safe in sloping glancing impact automobile brake perfrmance is safe and reliable.
The utility model is a kind of automobile hand brake, it is by a back board assembly (5), spring drag link mechanism (11), two brake shoe assemblys (8), adjusting play mechanism (13), restoring spring (9), (12), the automobile hand brake that lever (10) and brake wheel (4) are constituted, it is characterized in that: a supporting pin (2) and a long garden through hole are arranged on the fixed block of back board assembly (5), a wedge type mechanism and supporting pin (2) in two brake shoe assembly (8) one end clampings, and wedge type mechanism is made up of wedge type pulling shaft (6) and a pair of slide block (3).
During operation, tie-bar bar (10) makes the wedge type mechanism action, two brake shoe assemblys (8) are opened and is pressed on the inwall of brake wheel (4).Simultaneously again under the effect of brake wheel (4) rotating torque autoamtic boosting, a brake shoe assembly (8) is driven another brake shoe assembly (8) to be pressed on the supporting pin (2), two brake shoe assemblys (8) produce very big friction moment with brake wheel (4) inwall, reach the purpose of automobile brake.
Below in conjunction with accompanying drawing an embodiment of the present utility model is done detailed explanation.Fig. 1 is the front view of a kind of automobile hand brake of the utility model.Fig. 2 is a section-drawing of the present utility model.
In the accompanying drawings, the steel plate by three millimeters thick strikes out garden shape backboard, and there is a Da Yuan hole centre, around the hole four screw holes is arranged, and has a long garden through hole and a supporting pin (2) to constitute back board assembly (5) on the protruding fixed block of backboard.Constitute two brake shoe assemblys (8) by friction lining, shoe plate, the tendons of beef, mutton or pork.Two brake shoe assemblys (8) one lateral support are fixed on two brake shoe assemblys (8) floating ground on the back board assembly (5) by spring drag link mechanism (11) at the high spot of back board assembly (5).Two brake shoe assemblys (8) one ends have an one transverse plane and one and half garden arcs.Have in one transverse plane and one pair two 20 ° to 30 ° all can and get best angle be 25 ° the inclined-plane, outside have the slide block (3) of side channel to match, and can on the fixed block of back board assembly (5), slide, half garden arc and supporting pin (2) join.Top have two 20 ° to 30 ° all can the inclined-plane and to get best angle be to match in the middle of the long garden through hole that there is axial elongated slot 25 ° of inclined-planes and bottom and radially has the wedge type pulling shaft (6) in Chang Yuan hole to pass back board assembly (5) is contained in the slide block (3) on a pair of 25 ° of inclined-planes, constitute wedge type mechanism.The other end of two brake shoe assemblys (8) and adjusting play mechanism (13) join, restoring spring (9) and (12) are hung on two brake shoe assemblys (8), and lever (10) packs in the axial elongated slot of wedge type pulling shaft (6), will sell (7) passes the radially Chang Yuan hole of wedge type pulling shaft (6) and be connected with lever (10).Lever (10) one stomidiums and bearing join, and brake wheel (4) is installed, and constitute the utility model.
Back board assembly (5) with by four screw retention on the end face of the change speed gear box of automobile.Brake wheel (4) is preceding to be fixed with spline housing, and the back fixes with the flange yoke (1) of transmission shaft.Pull bar (10) outer end links to each other with backguy, the handle of automobile.
Glancing impact, handle is by backguy, lever (10) is pulled out wedge type pulling shaft (6), under the promotion on 25 ° of inclined-planes of wedge type pulling shaft (6), push two brake shoe assemblys (8) open by slide block (3), make it to be pressed on the inwall of brake wheel (4), staying sloping torque reaction at automobile simultaneously is delivered on the brake wheel (4) through transmission shaft, under the autoamtic boosting of torque reaction, wedge type mechanism moves in the through hole of the long garden of back board assembly (5) with two brake shoe assemblys (8), one brake shoe assembly (8) is promoted another brake shoe assembly (8) one ends half garden arc by adjusting play mechanism (13) to be pressed on the supporting pin (2), two brake shoe assemblys this moment (8) are pressed in more tightly and produce great friction moment on the inwall of brake wheel (4), two brake shoe assemblys (8) and brake wheel (4) are become one, transmission shaft can not be rotated, reach the purpose of automobile braking in the slope.
Brake off, release handle under the effect of restoring spring, makes backguy, lever (10), wedge type pulling shaft (6), slide block (3), two brake shoe assemblys (8) return original position again, throw off with brake wheel (4), this time be the brake off state.
The utility model is owing to adopt wedge type mechanism, two-way autoamtic boosting formula structure, and it has the advantages that braking moment is big and braking moments two directions equate. Through the many experiments proof its obvious advantage is arranged: it has the security reliability of good braking. In simulated experiment data on the experimental bench be: automobile is equal with the braking moment of the lower Parking in slope and all more than 1000Nm on the slope. In roadway experiment, use one grade of startup, reverse gear to start and all can not start And put out a fire. Automobile is fully loaded with on 30% slope, and automobile is done the both direction parking braking, can guarantee that automobile braking safety is reliable. The utility model is a kind of comparatively desirable hand brake for light automobile.
