Abstract
The utility model discloses a drum brake cable fixing structure, which relates to the field of drum parking brakes and comprises a drum brake, a shoe, a pull arm, a cable guide rail, a guide rail spring and a hand brake cable, wherein the lower part of the drum brake is provided with the cable guide rail, and one end of the cable guide rail is provided with a brake cable hole; the pull arm is arranged on the stay cable guide rail, the head of the pull arm is arranged close to a stay cable hole of the brake, and the tail of the pull arm is connected with and drives a shoe plate arranged on the drum brake through a guide rail spring; hand brake cable one end is connected the interior hand brake of car, and the hand brake cable other end is filled in the stopper cable downthehole connection and is driven the arm-drag, realizes that the cable is fixed. The utility model has the advantages that: the time consumption for assembling the stay cable by the drum brake is reduced, and the assembling cost is reduced; the tail of the guide rail uses a spring to eliminate the gap between the head of the stay cable and the hook of the pull arm, and the hidden trouble of unhooking failure of the parking stay cable is eliminated.
Description
Technical Field
The utility model relates to a drum-type parking brake's field, concretely relates to drum-type brake cable fixed knot constructs.
Background
The existing drum brake parking cable adopts a structure that a pull arm is manually hung in a guide rail, and the defects existing in the technical scheme are as follows:
1. the drum brake parking cable is in a semi-closed state, only the cable guide after the pull arm is installed can be provided, the head of the cable cannot be guided to the pull arm hook in the cable installation process, and the cable head needs to be installed manually;
2. the semi-closed guide rail is far away from the pull arm hook, and the tail end of the semi-closed guide rail is not provided with a spring, so that the gap cannot be completely eliminated after the semi-closed guide rail is installed, and the head of the stay cable easily falls out of the pull arm hook in a non-braking state, so that the parking brake fails.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art, and provides a drum brake cable fixing structure, which solves the technical problem that the drum brake parking cable is manually installed at the pull arm hook and is complex in operation; the problem of the potential safety hazard that the head easily falls out of the pull arm hook of a drum brake without a spring guide rail structure in a non-braking state is solved.
The purpose of the utility model is accomplished through following technical scheme: the drum brake cable fixing structure comprises a drum brake, a shoe plate, a pull arm, a cable guide rail, a guide rail spring and a hand brake cable, wherein the lower part of the drum brake is provided with the cable guide rail, and one end of the cable guide rail is provided with a brake cable hole; the pull arm is arranged on the stay cable guide rail, the head of the pull arm is arranged close to a stay cable hole of the brake, and the tail of the pull arm is connected with and drives a shoe plate arranged on the drum brake through a guide rail spring; hand brake cable one end is connected the interior hand brake of car, and the hand brake cable other end is filled in the stopper cable downthehole connection and is driven the arm-drag, realizes that the cable is fixed.
As the preferred technical scheme, the inhaul cable guide rail adopts a totally enclosed structure.
The utility model has the advantages that:
1. the time consumption for assembling the stay cable by the drum brake is reduced, and the assembling cost is reduced;
2. the tail of the guide rail uses a spring to eliminate the gap between the head of the stay cable and the hook of the pull arm, and the hidden trouble of unhooking failure of the parking stay cable is eliminated.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: drum brake 1, shoe 2, single arm 3, cable guide 4, guide rail spring 5, stopper cable hole 6.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached figure 1, the drum brake cable fixing structure comprises a drum brake 1, a shoe 2, a pull arm 3, a cable guide rail 4, a guide rail spring 5 and a hand brake cable, wherein the lower part of the drum brake 1 is provided with the cable guide rail 4 (adopting a fully closed guide rail structure), and one end of the cable guide rail 4 is provided with a brake cable hole 6; the pull arm 3 is arranged on a cable guide rail 4, the head of the pull arm 3 is arranged close to a brake cable hole 6, and the tail of the pull arm 3 is connected with and drives a shoe 2 arranged on the drum brake 1 through a guide rail spring 5; hand brake in the car is connected to manual brake cable one end, and the manual brake cable other end is filled in stopper cable hole 6 in-connection and is driven arm-drag 3, realizes that the cable is fixed.
The utility model discloses a working process: when the hand brake cable is installed, the hand brake cable is only required to be plugged into the brake cable hole 6 to complete installation, the head of the cable is not required to be hung into the hook 3 of the pull arm manually again, time consumption of an assembly process of the drum brake is reduced, steps of the assembly process are reduced, the cost of the assembly process is reduced, a guide rail spring 5 guide structure is possessed simultaneously, and the failure rate of the parking cable is reduced.
When the drum brake 1 is used for parking braking, a driver pulls a hand brake and transmits the hand brake cable to the pull arm 3, so that the shoe 2 is expanded to abut against a brake drum to achieve a parking effect, the hand brake cable is in a loose state in a non-braking state, the head of the hand brake cable hung at the hook of the pull arm 3 is in an unstressed state, if the head of the hand brake cable is shaken violently in the driving process of a vehicle, the head of the hand brake cable is easy to fall out of the hook of the pull arm 3, the parking brake adopting the prior art scheme fails to cause the vehicle to be parked on a slope, a totally enclosed type cable guide rail 4 is designed at the position where the hand brake cable enters a bottom plate, and a guide rail spring 5 is used for eliminating the gap between the pull cable head and the hook of the pull arm, so that the occurrence rate of parking failure is reduced, the assembly time of products is reduced, the assembly process cost is reduced, the occurrence of parking failure and the emergency auxiliary parking brake cannot be used is restrained, fundamentally restraining the parking of drum brake scheduling problem.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
