Abstract
The utility model belongs to the technical field of the stopper technique and specifically relates to an adopt electronic parking braking's drum brake. The utility model provides an adopt drum brake of electron parking braking, includes drum brake, motor drive unit, its characterized in that: a motor driving unit is arranged on one side of the drum brake and is fixedly connected with the drum brake through a connecting bracket and a fastening bolt; an output shaft of the motor driving unit is connected with one end of a threaded rod, the other end of the threaded rod is connected with one end of a stay cable, and a pull arm is connected above the other end of the stay cable. Compared with the prior art, the drum brake adopting the electronic parking brake is provided, the electronic parking brake system is integrated on the drum brake, and the brake cost can be well reduced. And because the drum brake is of a relatively closed structure, powder abraded by the friction plate can be effectively prevented from entering air, and the environment is protected.
Description
Technical Field
The utility model belongs to the technical field of the stopper technique and specifically relates to an adopt electronic parking braking's drum brake.
Background
With the development of the development era of science and technology, people have higher and higher requirements on the automobile brake system. The traditional brake needs to be matched with a hand brake pull rod and an inhaul cable to realize parking braking, occupies more space in a vehicle, and is not beneficial to arrangement of chassis parts. With the development trend of automobile electromotion, intellectualization and networking, the traditional brake can not meet the requirements of a new era.
Several years ago, the advent of calipers integrated with electronic parking brakes has met new demands of people, but this has brought about a substantial increase in cost. And due to the structure that the caliper is exposed, powder generated by abrasion of the friction plate is completely discharged into the air, so that the caliper is not beneficial to the environment. Currently, europe and developed countries such as the united states have begun to specify regulations for controlling the harmful components in friction plates from entering the air.
Disclosure of Invention
The utility model discloses an overcome prior art not enough, provide an adopt electronic parking braking's drum brake, with electronic parking braking system integrated to the drum brake above, reduction electronic parking braking cost that can be fine.
In order to achieve the purpose, the drum brake adopting the electronic parking brake is designed, comprises the drum brake and a motor driving unit, and is characterized in that: a motor driving unit is arranged on one side of the drum brake and is fixedly connected with the drum brake through a connecting bracket and a fastening bolt; an output shaft of the motor driving unit is connected with one end of a threaded rod, the other end of the threaded rod is connected with one end of a stay cable, and a pull arm is connected above the other end of the stay cable.
One end of the inhaul cable is embedded in the other end of the threaded rod.
The stay cable obliquely enters the drum brake, and the other end of the stay cable is connected with the pull arm through the stay cable guide block.
The drum brake is a leading shoe type drum brake.
Compared with the prior art, the utility model, a provide an adopt electronic parking braking's drum brake, with electronic parking braking system integrated to the drum brake above, reduction stopper cost that can be fine. And because the drum brake is of a relatively closed structure, powder abraded by the friction plate can be effectively prevented from entering air, and the environment is protected.

Referring to fig. 2 to 4, 1 is a drum brake, 2 is a motor driving unit, 3 is a connecting bracket, 4 is a fastening bolt, 5 is a cable, 6 is a draw arm, 7 is a threaded rod, and 8 is a cable guide block.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 4, a motor driving unit 2 is provided at one side of a drum brake 1, and the motor driving unit 2 is fixedly connected to the drum brake 1 through a connecting bracket 3 and a fastening bolt 4; an output shaft of the motor driving unit 2 is connected with one end of a threaded rod 7, the other end of the threaded rod 7 is connected with one end of a stay cable 5, and a pull arm 6 is connected above the other end of the stay cable 5.
One end of the stay 5 is embedded inside the other end of the threaded rod 7.
The stay cable 5 obliquely enters the drum brake 1, and the other end of the stay cable 5 is connected with the pull arm 6 through a stay cable guide block 8; guided by the inhaul cable guide block 8, changes direction and extends to the pull arm 6.
The drum brake 1 is a leading shoe drum brake.
On the basis of a traditional leading shoe type drum brake with an automatic adjusting mechanism for the belt gap, a motor driving unit is integrated, the motor driving unit is fixed on the drum brake through a connecting support and a fastening bolt, a pull rod of the traditional hand brake is replaced by the motor driving unit to tension a pull cable, and therefore the pull arm is pulled to achieve the parking function.
The pull rope force of the motor driving unit is 1000-3000N; time required to achieve parking: less than 2 s; parking strategy: providing multi-gear pulling force according to the gradient value; service life: more than 100,000 times; the functions can be realized: static tensioning and releasing; the driving away is automatically released; the actuator has a dynamic braking function; a rolling re-tensioning function; supporting the function of a rotary drum test bed; motor overheating protection (abnormal use); accepting an external request to release or tighten; and maintaining the function.
