Chinese invention patent application specification CN1032577A discloses a kind of method and apparatus that is converted to braking force with force of inertia on April 26th, 89, this device is by a follow mechanism and the main stop mechanism that plays the conversion effect, the force of inertia that mobile had is converted to braking external force, then through the braking external force of force-increasing mechanism reinforcement as the next stage stop mechanism, can not drive the stop mechanism of conversion effect at last by unidirectional top power apparatus, reach the purpose of brake wheel.The mechanism of this complexity not only makes its enforcement on wheel become difficulty and has increased failure factor, also because its force-increasing mechanism makes braking maneuver postpone and deceleration and stopping performance is rough.
Purpose of the present invention provide in order to overcome above-mentioned shortcoming just a kind of can be directly at the wheel place, promptly the rotation inertia force with wheel is converted to the device that braking force comes the drive wheels drg.
For achieving the above object, the present invention has designed the actuating device on a kind of back-plate that can be installed in the common wheel drg, this actuating device comprise one can be with being braked that wheel carries out wipe contact the friction wheel that thereupon rotates, this friction wheel links by wheel shaft and the wheel shaft bolster that supports it, when the restricted moving actuating force effect campaign of wheel shaft bolster, drive the friction wheel motion by wheel shaft, make friction wheel be braked the wheel contact, the brake shoe expander that is used for strutting brake shoe brake cheek is housed on the described friction wheel, when friction wheel be braked the wheel contact, when being braked wheel and rotating, drive the brake shoe expander that is installed in above it and rotate, strut the brake shoe brake cheek brake wheel.In order to obtain suitable braking moment, friction wheel can drive brake shoe expander by variable gear.
The invention has the advantages that it provides braking force without any need for the force-increasing mechanism of braking force source and braking force driving system and complexity to car side brake, only adopt simple structure to utilize the rotation inertia force of wheel itself just can carry out the failure-free braking to wheel, thereby improved the reliability of brake system of car widely, it also have simple in structure, the braking time delay is short and the advantage of good braking effect.
Accompanying drawing is a principle schematic of the present invention.
Further specify specific implementation method of the present invention below in conjunction with accompanying drawing.Accompanying drawing is depicted as the present invention and is applied in a example on the common drum-type car side brake, this drum brake mechanism (A) comprises back-plate (21), brake shoe brake cheek (18), brake wheel (17) and brake shoe brake cheek returning pull-spring (22), and this brake wheel (17) promptly is equivalent to the described wheel that is braked.Described actuating device (B) is positioned at the end that struts of brake shoe brake cheek (18), it comprises the friction wheel (1) that the brake shoe expander (19) that is used for strutting brake shoe brake cheek (18) is housed above, this friction wheel (1) links by wheel shaft (2) and the wheel shaft bolster (4) that supports it, when wheel shaft bolster (4) is subjected to the brake operating force effect and moves, drive friction wheel (1) motion by wheel shaft (2), it is contacted with brake wheel (17).Brake shoe expander (19) is refuted pin (3) by two and is inserted in and links with friction wheel (1) in two bending grooves (16) on the friction wheel (1) and rotate thereupon, and they can link by recoil spring or variable gear.One U-lag (20) is arranged on the back-plate (21), and an end of wheel shaft (2) stretches out and is embedded in the groove to bear the different support power in accentric brake shoe expander (19) both sides.The lower end of wheel shaft bolster (4) links by pin (5) and wheel shaft supporting plate (14) and control pull rod (6), and wheel shaft supporting plate (14) is fixed on the back-plate (21) by a rotary load bearing pin (15).Control pull rod (6) is drawn in order clearly to express hook box (7), in the reality, fixedly the load bearing pin (15) of wheel shaft supporting plate (14) the close pin (5) that moves to wheel shaft supporting plate (14) is located, and wheel shaft supporting plate (14) itself just can be held concurrently and directly be accepted actuating force for control stalk.For making two brake shoe brake cheek (18) wearing and tearing evenly, the pivot center of brake shoe expander among the figure (19) is in its position on the upper side, center.One end of control pull rod (6) has the lead screw (13) and the reset tension spring (11) that is fixed on the pin (12) that are used for the adjusting yoke stroke, is used for regulating the gap between friction wheel (1) and the brake wheel (17) and keeping it.A hook box (7) that is fixed on the back-plate (21) is arranged on the control pull rod (6), when control pull rod (6) is moved in this box, can be tangled and decontrol, in order to keep and to discharge the braking mode of car side brake.The operation pull bar (8) that is used for stirring control pull rod (6) with refute bar (9) and link to each other by the both sides of bearing pin (10) from back-plate (21), and be the axle center co-rotation with bearing pin (10).Refute the extension pin of bar (9) confutation control pull rod (6) termination.
