Abstract
The utility model relates to a drum-like hand brake which can directly replace the disc type parking brake of the NANJING 130 type gearbox, comprising a control mechanism and a brake backing plate 24. A lever 10 which can pull a level arm 15 is arranged on the connecting yoke 8 of the control mechanism, and the level arm can push aside two brake shoes through a pushing plate 20. One end of each brake shoe is hitched by a tension spring 18, so that two ends of the two brake shoes embrace and are supported on a supporting pin 19; the other end of each brake shoe is hitched and inserted on a gap adjustor 13 by a resetting tension spring 14. The utility model has the advantages of simple and compact structure, flexible operation, convenient and easy assembling and disassembling, etc., being suitable for types of cars such as NANJING 130 type, JIEFANG type, etc.
Description
The utility model relates to a kind of drum-type hand brake, particularly a kind of drum-type hand brake that is used on the type change speed gear box of Nanjing-130.
The hand brake of existing Nanjing-130 type change speed gear box all adopts the disc type Parking Brake, because the moment of its brake shoe brake cheek is to directly act on brake support frame, thereby at the car emergency glancing impact, often make its brake support frame fracture damage because of moment is excessive, drawing crack damages even the higher mitis metal of intensity also usually is subjected to moment loading, causes its brake failure, influences running safety, the disc type vehicle stop brake mechanism complexity of NJ-130 change speed gear box is made difficult in addition.
The purpose of this utility model designs a kind of simple in structure exactly, makes easily, and is safe and reliable, can bear the drum-type hand brake of the suitable Nanjing-130 type automobile gearbox of big moment loading.
The purpose of this utility model realizes by following structure: the drum-type hand brake, include by joystick, tooth plate, ratchet, adjusting screw(rod), steering unit and brake support plate that shaft clevis is formed, its principal character is: the lever that is connected to a pulling pull bar on shaft clevis, the pull bar pulling withstands on the throw of lever that rotates around the axis in the push pedal, brake shoe with lining is fixed on the interior brake support plate of brake wheel, one end of two brake shoe brake cheek is pulled on the bolster and by push pedal by extension spring and backs down, the other end of two brake shoe brake cheek is held by reset tension spring and is inserted on the clearance adjuster mutually, when needing braking during standstill, chaufeur only needs toward the braking direction pulling joystick, make lever rotate an angle by adjusting screw(rod) and shaft clevis simultaneously, make push pedal push brake shoe brake cheek open by pull bar pull lever arm again, at this moment the outer friction lining of brake shoe brake cheek is convenient to very big friction force of brake wheel inside face generation, since brake wheel be with the driving system of wheel rotate together and brake shoe brake cheek is relative static being installed on the gear-box case, so this friction force has just played the effect to automobile brake.Because the effect of ratchet braking force when the cancellation actuating force can not unclamp automatically, he will press the button earlier ratchet disengaging tooth plate is got final product joystick Hui Song again to terminal point when chaufeur need unclamp Parking, and clearance adjuster is a device of regulating gap between brake wheel and the friction lining.
The utility model compared with prior art has following advantage:
1. this drg can directly be replaced the disc type Parking Brake of Nanjing 130 type change speed gear boxs, and lock torque is big, and manoeuvrable is reliable;
2. this brake structural is simply compact, and the part number is few and intensity is high, and is not fragile, easy accessibility.
3. change the protruding commentaries on classics transmission manipulation of general steel rope transmission manipulation and lever and be lever push pedal transmission, transmission is laborsaving, rapid, and long service life, and according to the two-way performance that helps the gesture self energizing effort is arranged.
Description of drawings of the present utility model is as follows:
Fig. 1 is the utility model transmission principle figure;
Fig. 2 is the utility model structural representation;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the brake shoe brake cheek driving surface scheme drawing that combines with rest pin;
Among the figure: 1 ratchet release button, 2 joysticks, 3 bearing pins, 4 tooth plates, 5 limiting devices, 6 ratchets, 7 adjusting screw(rod)s, 8 shaft cleviss, 9 bearing pins, 10 levers, 11 small clevis pin with head, 12 pull bars, 13 clearance adjusters, 14 reset tension springs, 15 throw of levers, 16 brake shoe brake cheek, 17 brake wheels, 18 extension springs, 19 bolsters, 20 push pedals, 21 friction linings, 22 unsteady support pins, 23 rotating shafts, 24 brake support plates.
The utility model will be further described below in conjunction with drawings and Examples:
As shown in Figure 1: the utility model includes by joystick 2, tooth plate 4, ratchet 6, steering unit that adjusting screw(rod) 7 and shaft clevis 8 etc. are formed and the brake support plate 24 that can cooperate with the change-speed box of Nanjing 130 type automobiles, on shaft clevis, be connected to the lever 10 of stretchy pull bar 12 by bearing pin 9, pull bar 12 pulling withstands in the push pedal 20 23 throw of levers 15 that rotate around the shaft, the brake shoe brake cheek 16 of band friction lining 21 is fixed on the brake support plate in the brake wheel 17, brake wheel is to be fixed on the driving system of wheel, one end of two brake shoe brake cheek is held to be bearing on the rest pin 19 and by push pedal by extension spring 18 and is backed down, the brake shoe brake cheek other end is held by reset tension spring 14 and is inserted in mutually on the clearance adjuster 13, as shown in Figure 2; In order to make brake shoe brake cheek is full floating, so that brake shoe brake cheek can fully combine with brake wheel, thereby reach maximum braking moment, brake shoe brake cheek can be floated by unsteady support pin 22 and be fixed on brake support plate, as shown in Figure 3, the driving surface that brake shoe brake cheek combines with rest pin can be two and waits radius disloyalty arc surfaces, as shown in Figure 4, also can make the radius of the circular arc driving surface that brake shoe brake cheek combines with rest pin be equal to or greater than the radius of rest pin.Brake support plate can adopt the HT20-40 ironcasting, to improve the intensity of base plate, improves the bearing strength of the utility model emergency brake torsional forces.
