Abstract
The utility model provides a multifunctional hand brake for motor vehicles, comprising a machine frame, a brake disk, a front shoe plate, a back shoe plate, a draw arm and a large draw rod. The utility model is characterized in that the back shoe plate can translate along the disc surface of the brake disc, the outer side surface of the back shoe plate is slope-shaped, and a positioning block which is fixed on the machine frame is arranged outside the back shoe plate. The Multifunctional hand brake which is provided by the utility model overcomes the defects of complicated structure and poor braking effect in existing hand brakes. The utility model can brake by using the principle of wedge action, and can guarantee the running and stopping safety of vehicles on slopes in mountain areas; the utility model has the advantages of small input force and large braking force.
Description
The utility model relates to the hand brake of a kind of brake equipment of self-propelled vehicle, particularly automobile.
The Parking Brake that uses on the existing automobile is drum brake mechanism mostly, and its complex structure, braking effect are poor.Particularly the braking force characteristic of drg can not be regulated and control, in ramp Parking, not easy to operate when travelling.Chinese patent 94208469.1 provides a kind of automatic control disc type reinforcement Parking Brake, this brake service is convenient, can auto-control, guarantee vehicle safety, but this brake braking force is little and it is slow to increase, and can't fully satisfy the needs of vehicle in driving of ramp, mountain area and Parking.
The purpose of this utility model is at the problems referred to above, and a kind of hand brake with self energizing effort mechanism is provided, and it produces bigger braking force with the less input force of navigating mate, has overcome weak point of the prior art effectively.
The purpose of this utility model is to adopt following technical proposal to realize: the multifunctional hand drg comprises frame, brake disc, be arranged on card before and after the brake disc preceding shoe plate and back shoe plate, is connected before shoe plate and the torque arm of back shoe plate and pull bar greatly, big pull bar tail end is connected with brake handle by stay cord, the top withstands on the preceding shoe plate, and connects with torque arm by pin.The back shoe plate of this drg can be along the translation of brake disc card, and its lateral surface is slope shape, and there is a locating piece that is fixed on the frame in the outside of back shoe plate.When this drg used, brake handle was controlled big pull bar tail end by stay cord.Because big pull bar top withstands on the preceding shoe plate, and connects with torque arm by pin,, the preceding shoe plate of brake disc both sides and back shoe plate are clamped brake disc therefore by lever principle.Because of the back shoe plate can be along the card direction translational of brake disc, after the back shoe plate was pressed on the brake disc, the rotating inertia force of system fortune dish can make shoe plate depart from the home position, but the locating piece in the shoe plate outside, back will after shoe plate block.Simultaneously, the lateral surface of back shoe plate is slope shape, causes the back shoe plate to produce wedge action between locating piece and brake disc, thus the chucking brake disc.The force of inertia of brake disc is big more, and back shoe plate just blocks tightly more, and the braking force of generation is also big more.Therefore, this multifunctional hand drg has the self energizing effort function, has overcome weak point of the prior art, has improved the performance of hand brake.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is that the master of multifunctional hand drg provided by the utility model looks scheme drawing.
Fig. 2 is the schematic rear view of multifunctional hand drg.
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in the figure, the multifunctional hand drg comprises frame (1), brake disc (2), preceding shoe plate (4), back shoe plate (5), torque arm (3), big pull bar (7) and locating piece (6), frame (1) is fixed on the Automotive transmission, brake disc (2) links to each other with the bead of two of change-speed boxs, big pull bar (7) top withstands on the preceding shoe plate (4), and connects with torque arm (3) by pin (9).The cross-sectional plane of back shoe plate (5) is equicrural triangle, and locating piece (6) is consistent with the gradient of back shoe plate (5) lateral surface with the gradient of the side of back shoe plate (5) contact.In the present embodiment, a hole (10) is arranged in the middle of the locating piece (6), have a reset lever (11), this reset lever (11) to pass the hole (10) on the locating piece (6) and stretch out on the lateral surface of back shoe plate (5).Simultaneously, on reset lever (11), be provided with retracing spring (12).When drg returned to releasing orientation by braking, retracing spring (12) can make back shoe plate (5) be returned to original position.
This multifunctional hand drg frame (1) is provided with function arm (8), connects by pivot pin (13) between function arm (8) and the frame (1).The tail end of function arm (8) connects with brake handle by stay cord (14), and there is a location plush copper (15) on function arm (8) top.Have knock hole (16) on the reset lever (11), this knock hole (16) is passed on the top of function arm (8).When releasing of brake, location plush copper (15) is in the knock hole (16); When drg is in braking mode, reset lever (11) departs from the home position, and location plush copper (15) is exposed to outside the knock hole (16), and because of the pulling of stay cord (14), make function arm (8) rotating certain angle, the location plush copper (15) depart from knock hole (16) over against the position.Like this, reset and when reversing sense advanced, the plush copper (15) that can be positioned when being returned to midway location after back shoe plate (5) eases out was blocked, make it can not continue to depart from, guarantee the cruising of automobile towards opposite side when automobile.In the present embodiment, between function arm (8) tail end and stay cord (14), also set up lower link bar (17), be used for control and regulatory function arm (8).Between big pull bar (7) and frame (1), recover spring (18) in addition.Behind the release the brake handle, big pull bar (7) is got back to original position under the effect that recovers spring (18), and drg returns to original state.
This Multifunctional hand brake is compared with common hand brake, has following advantages:
1, Input Forces is little, and brake force is big. Because the utility model adopts the wedging principle Produce brake force, therefore only need littler Input Forces, can obtain bigger braking Power, and can automatically increase.
2, automobile when uphill starting without release brake, pine again after the starting by the time Open. Like this, guarantee that automobile is safe, easy to operate at the ramp going.
The utility model also has the emergency brake function except Parking is used, particularly under the malfunctioning situation of automobile service brake, can automobile be halted, and generation avoids traffic accident.The utility model can be widely used on the various vehicles.
