Abstract
The invention discloses a tensile testing device for an automobile hand brake, which is characterized by comprising a platform, a vertical frame and a lifting arm, wherein, the platform is equipped with a fixing device for the automobile hand brake; the vertical frame is fixedly arranged on the platform; one end of the lifting arm is movably arranged on the vertical frame, and a support frame is fixedly arranged on the other end of the lifting arm; and one end of the support frame is equipped with an unlocking device, and the other end of the support frame is cooperatively connected with a power unit which is equipped with a force sensor. The tensile testing device using the structure has simple structure, lower production cost and convenient operation.
Description
Technical field
The present invention relates to a kind of automobile hand brake proving installation, relate in particular to a kind of tensile testing device for automobile hand brake.
Background technology
Parking brake is different from service brake, and it is the simple mode with backguy, when automobile is stopped, keeps the stability of automobile.
The Chinese patent Granted publication number is CN201049623Y, Granted publication day is that the patent of invention on April 23rd, 2008 discloses a kind of automobile hand brake device, keep existing automobile hand brake structure, only installing a spring additional above the brake drum rocking arm that has the automobile hand brake structure now and between the nut of stay-bolt, this spring housing is on stay-bolt.When Parking is loosed one's grip when leaving hand brake lever, owing to add shock mount the effect of deposit elastic force is arranged, make brake drum hoof rocking arm continue to remain on the state that compresses, thereby eliminated that the brake drum hoof rocking arm that causes owing to each gap, position retreats, brake drum and shoe plate friction force weakens the defective that has caused Parking ineffective.Though this improved automobile hand brake device, it is simple in structure, be easy to transform, cost is low, practical, safe and reliable.Required dynamics was too big and can't normally use the automobile hand brake device when but the operator pull-up hand brake lever can occur when reality is used, therefore before reality is used the automobile hand brake device during to the pull-up hand brake lever required dynamics test the particularly important of change.
Summary of the invention
Technical matters to be solved by this invention provide a kind of simple in structure, production cost is lower, and easy to operate tensile testing device for automobile hand brake.
For realizing above purpose, the technology used in the present invention solution is: a kind of tensile testing device for automobile hand brake, it is characterized in that: comprise platform, stand and carry arm, described platform is provided with an automobile hand brake stationary installation, described stand is fixedly set on the described platform, one end of described carry arm is movably set in the described stand, the other end of described carry arm is set with a bracing frame, one end of this bracing frame is provided with a tripper, and the other end of bracing frame connects with the propulsion system that force transducer is installed.
Support frame as described above is provided with a boss.
Described stationary installation is one to be fixedly set in the riser on the described platform, this riser be provided with the automobile hand brake body on fixture first groove and second cell body that adapt.
Described tripper is the expansion link of first air cylinder driven, and the expansion link of this first air cylinder driven is arranged at an end of bracing frame and roughly parallel in described carry arm.
Described propulsion system are the pull bar of an air cylinder driven.
Compared with prior art, effect intentionally of the present invention is:
1. because tensile testing device for automobile hand brake of the present invention comprises platform, stand and carry arm, platform is provided with the automobile hand brake stationary installation, stand is fixed on the platform, one end of carry arm is movably set in the stand, the other end of carry arm is set with a bracing frame, one end of this bracing frame is provided with a tripper, and the other end of bracing frame connects with the propulsion system that force transducer is installed.Whole device mainly is made of simple in structure stationary installation, carry arm and propulsion system that force transducer is installed, production cost is not high.Therefore the present invention is simple in structure, production cost is lower.
2. owing in the tensile testing device for automobile hand brake actual mechanical process of the present invention fixture on the automobile hand brake body placed first groove and second cell body on the perpendicular version, the parking brake pull bar contacts with bracing frame, tripper is pressed the unlock button on the parking brake pull bar, propulsion system drive bracing frame and lift the parking brake pull bar, because force transducer is installed on the propulsion system, therefore force transducer can effectively detect the size that bracing frame lifts the required power of parking brake pull bar, whole operation process safe ready, so the present invention is easy to operate.
