Description
Technical field
The utility model relates to a kind of dribbling drum brake parking lash adjusting device.
Background technology
In recent years, because the relative drum brake of disk brake has the following advantages:
1, disk brake brake force under fluid power power-assisted is large and stable, has good braking performance on various road surface;
2, brake efficiency is far above drum brake;
3, air can directly by disc type brake dish, and the thermal diffusivity of disk brake is good;
Disk brake achieves develop rapidly, and due to the needs of parking, dribbling drum brake has also arisen at the historic moment.Dribbling drum brake one is made the disk brake of running brake and a drum brake making EPB is combined, the brake disc of disk brake made by the outer rim dish of double-acting brake disc, middle tympanic part is as the brake drum of drum brake, along with the use of dribbling drum brake, the wearing and tearing of Brake shoe lining and brake drum working face make the gap between hoof drum become large gradually, and then cause parking to lose efficacy (slip car), affect safety, therefore need to adjust the gap between hoof drum, but the gap adjustment between the drum of dribbling at present brake shoe drum is more complicated, need to disassemble brake, bothersomely to require great effort again, and there are differences due to the technical merit of staff, parking braking gap is difficult to ensure.
Utility model content
The utility model provides a kind of dribbling drum brake parking lash adjusting device, and object facilitates the gap between adjustment disk band drum-type brake shoe drum.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: dribbling drum brake parking lash adjusting device, comprise drive motors, the worm screw be connected with the motor shaft of drive motors, the worm gear coordinated with worm screw and be to be threaded and by the push rod of worm-gear driven moving linearly, push rod is also connected with the shoe brake of brake with worm gear in the both sides of worm gear.
Described drive motors is bolted on the back-plate of brake.
The both sides of described worm gear are respectively equipped with a sleeve pipe extended vertically, are provided with the internal thread be connected with described push rod in sleeve pipe, and the thread rotary orientation in two sleeve pipes is contrary.
Described push rod one end is inserted in described sleeve pipe and is connected with it, and the other end is connected with described shoe brake clamping.
The end that described push rod is connected with described shoe brake is provided with draw-in groove.
Dribbling drum brake parking lash adjusting device of the present utility model, worm screw is driven to rotate by drive motors, worm screw drives worm gear wheel, worm gear is threaded connection structure and drives push rod to move axially, and push rod promotes shoe brake motion, realizes the adjustment of drum-shoe clearance, simple to operate, reliable, convenient, fast, accurate, saving human resources, on the basis of not disassembling dribbling drum brake, the adjustment of drum-shoe clearance can be completed, good drum-shoe clearance can be ensured again.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model dribbling drum brake parking lash adjusting device;
Mark in above-mentioned figure is: 1, drive motors; 2, worm screw; 3, worm gear; 4, push rod; 5, draw-in groove; 6, sleeve pipe.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, be described in further detail detailed description of the invention of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technical scheme, and contribute to its enforcement.
As shown in Figure 1, a kind of dribbling drum brake of the utility model parking lash adjusting device, comprise drive motors 1, the worm screw 2 be fixedly connected with the motor shaft of drive motors 1, the worm gear 3 coordinated with worm screw 2 and at the both sides of worm gear 3 and worm gear 3 for being threaded and being driven the push rod 4 of moving linearly by worm gear 3, push rod 4 is also connected with the shoe brake of brake.
Specifically, as shown in Figure 1, drive motors 1 is bolted on the back-plate of brake by four.Worm screw 2 is matched with worm gear 3 formation Worm and worm-wheel gearing, a sleeve pipe extended vertically 6 is respectively equipped with in the center, both sides of worm gear 3, the internal thread be connected with push rod 4 is provided with in sleeve pipe 6, and thread rotary orientation in two sleeve pipes 6 is contrary, thus the push rod 4 that can promote both sides moves simultaneously.
As shown in Figure 1, one end of push rod 4 is inserted in sleeve pipe 6 and is connected with it, and this end of push rod 4 is provided with external screw thread, and push rod 4 and sleeve pipe 6 form worm drive.The other end of push rod 4 is connected with shoe brake clamping, and this end of push rod 4 is provided with a draw-in groove 5, to be stuck on shoe brake relevant position.
When driver feels that parking was lost efficacy, press drum-shoe clearance adjustment button, drive motors 1 is energized and rotates, drive motors 1 drives worm screw 2 to rotate, worm screw 2 drives worm gear 3 to rotate, worm gear 3 is threaded connection structure and drives push rod 4 to move axially, and push rod 4 promotes shoe brake motion, realizes the adjustment of drum-shoe clearance.
The motor pattern of drive motors 1 is realized by controller software, transfers by controlling the positive and negative of motor the increase and reduction that realize gap between hoof drum.Control program is as follows: it is zero that motor rotates forward adjustment parking gap, the then motor reversal requirement number of turns again, the number of turns of reversion according to the transmission of the drum-shoe clearance value (General Requirements is 2mm ~ 3mm) of designing requirement, worm and gear when pitch determine.When drive motors 1 does not work, due to worm gear 3 and the self-locking action of worm screw 2, worm gear 3 can not drive drive motors 1 to rotate, and ensures that the gap between hoof drum is reliable, stablizes.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
