Abstract
The utility model discloses a motor vehicle testing equipment drum brake device, comprising a drum (11) arranged on a stand (10). The shaft end of the drum (11) is provided with a braking wheel (12) and an outer-ring-fixing frame (21), wherein the braking wheel (12) is connected with the drum (11) in a driving way; the outer-ring-fixing frame (21) is fixedly connected with the stand (10); and a ring-shaped air bag (20) is arranged between the outer peripheral surface of the braking wheel (12) and the inner peripheral surface of the outer-ring-fixing frame (21). The ring-shaped air bag can generate a large enough brake force after being charged with compressed air, thus having good braking ability; the compressed air can be charged into or discharged out of the ring-shaped air bag rapidly so that the drum can be freely switched between a locking state and a free-rotation state, thus being favorable for increasing vehicle testing efficiency; and the device has simple structure, and can be conveniently applied to vehicle testing equipment such as a brake tester, a speedometer tester, an automobile chassis dynamometer, a free drum platform, and the like.
Description
Technical field
The utility model relates to motor vehicle detecting equipment, particularly a kind of drum brake device of motor vehicle detecting equipment.
Background technology
Motor vehicle detecting equipment such as brake test bench, velometer check-out console, road simulation dynamometer, free drum table etc., structurally all include rack-mounted left and right two series cylinders, each is made up of every series cylinder two or three axis cylinder parallel to each other.After being examined the motor vehicle test ending, need brake each cylinder by the drum brake device, so that motor vehicle energy successfully drives out, so be provided with the drum brake device in these motor vehicle detecting equipment in the pit that forms between two cylinders.
In existing motor vehicle check-out console, generally adopt the drum brake device of forming by brake ribbon that is arranged on the cylinder below and cylinder, cylinder upwards holds out against brake ribbon during brake, utilizes the friction that produces between brake ribbon and the cylinder to make drum braking.But the damping force that this brake modes produced is less relatively, especially can not make the cylinder secure ratcs, therefore tends to take place skidding in the motor vehicle starting-up process, normally sails out of check-out console thereby influence motor vehicle.At present, the drum brake device can't fail this problem of cylinder locking to be well solved always.
The utility model content
Technical problem to be solved in the utility model provides a kind of motor vehicle detecting equipment drum brake device with good braking ability.
The technical scheme that its technical matters that solves the utility model adopts is: motor vehicle detecting equipment drum brake device of the present utility model, comprise rack-mounted cylinder, it is characterized in that: the axle head of described cylinder is provided with braked wheel and outer shroud fixed mount, wherein braked wheel and cylinder are in transmission connection, outer shroud fixed mount and frame form a fixed connection, and are provided with annular air-pocket between the inner peripheral surface of the outer peripheral face of braked wheel and outer shroud fixed mount.
In technique scheme, described braked wheel and outer shroud fixed mount are arranged on the outside one end of cylinder.
The beneficial effects of the utility model are can produce enough big damping force after annular air-pocket charges into pressurized air, so have good braking ability; Because annular air-pocket can fill, put pressurized air fast, therefore can make cylinder at locking, freely rotates conversion fast between the two states, examine car efficient thereby help raising; Simple in structure, can be conveniently used on the motor vehicle detecting equipment such as brake test bench, velometer check-out console, road simulation dynamometer, free drum table.
Description of drawings
This instructions comprises as next width of cloth accompanying drawing:
Fig. 1 is the structural representation of motor vehicle detecting equipment drum brake device of the present utility model.
Parts, toponym and pairing mark among the figure: frame 10, cylinder 11, braked wheel 12, annular air-pocket 20, outer shroud fixed mount 21, support 22.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, motor vehicle detecting equipment drum brake device of the present utility model, comprise the cylinder 11 that is installed on the frame 10, the axle head of described cylinder 11 is provided with braked wheel 12 and outer shroud fixed mount 21, wherein braked wheel 12 is in transmission connection with cylinder 11, outer shroud fixed mount 21 forms a fixed connection with frame 10, is provided with annular air-pocket 20 between the inner peripheral surface of the outer peripheral face of braked wheel 12 and outer shroud fixed mount 21.After charging into pressurized air to annular air-pocket 20, the annular air-pocket 20 of expansion acts on the inner peripheral surface of the outer peripheral face of braked wheel 12 and outer shroud fixed mount 21, cylinder 11 is produced enough big damping force, so have good braking ability.After annular air-pocket 20 releases, cylinder 11 is free to rotate.Because annular air-pocket 20 can fill, put pressurized air fast, therefore can make cylinder 11 at locking, freely rotates conversion fast between the two states, examine car efficient thereby help raising.Because it is simple in structure, can be conveniently used on the motor vehicle detecting equipment such as brake test bench, velometer check-out console, road simulation dynamometer, free drum table.
Above-mentioned brake gear can be in two axle head settings of cylinder 11, also can be only in an axle head setting one by one of cylinder 11, and promptly described braked wheel 12 and outer shroud fixed mount 21 are arranged on the outside one end of cylinder 11.A kind of the simplest mounting structure of described outer shroud fixed mount 21 has been shown among Fig. 1, and promptly outer shroud fixed mount 21 is fixedly mounted on the support 22, and support 22 is fixedlyed connected with frame 10.
Some principles of the above the utility model motor vehicle detecting equipment drum brake device that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
