The automotive wheel anti-lock braking system is directional stability and the security when improving automobile brake.In recent ten years, wheel anti-lock braking system (being called for short ABS) is successively installed on the large and small passenger vehicle of Compulsory Feature, the high capacity waggon by various countries, but existing ABS check-out console can not detect the slip rate of wheel.
The utility model content
The utility model provides a kind of Automobile Anti-lock Braking parts and system performance verifying attachment that can detect wheel slip.
Realize the Automobile Anti-lock Braking parts and the system performance verifying attachment of the utility model purpose, comprise frequency modulation motor, left free cylinder and right free cylinder; Said frequency modulation motor drives left head roll through torque sensor, and said left head roll links to each other with an end of right head roll through shaft coupling, and the other end of said right head roll is equipped with flywheel; Free cylinder in a said left side and said left head roll are oppositely arranged in the both sides of said wheel, and free cylinder in the said right side and said right head roll are oppositely arranged in the both sides of said wheel; One end of free cylinder in a said left side and right free cylinder is equipped with scrambler respectively, between said left head roll and the left free cylinder left lifting jack is housed, and between said right head roll and the right free cylinder right lifting jack is housed.
Automobile Anti-lock Braking parts of the utility model and system performance verifying attachment can detect ABS parts duty, and ability precise real-time detection wheel slip, obtain the static and dynamic duty effect of anti-lock braking system(ABS).Solve all kinds of in the past brake test benches and can't detect wheel slip, obtained the problem of estimating the anti-block braking system of car quantizating index; And realized that automobile ABS parts and system detect on the same stage.
Description of drawings
Fig. 1 is the structural representation of the utility model Automobile Anti-lock Braking parts and system performance verifying attachment.
Fig. 2 is the left view of Fig. 1.
Embodiment
Like Fig. 1, shown in 2, Automobile Anti-lock Braking parts of the utility model and system performance verifying attachment comprise frequency modulation motor 8, left free cylinder 4 and right free cylinder 5; Said frequency modulation motor 8 drives left head roll 2 through torque sensor 9, and said left head roll 2 links to each other with an end of right head roll 3 through shaft coupling 12, and the other end of said right head roll 3 is equipped with flywheel 10; The free cylinder 4 in a said left side is oppositely arranged in the both sides of said wheel 1 with said left head roll 2, and the free cylinder 5 in the said right side is oppositely arranged in the both sides of said wheel 1 with said right head roll 3; One end of free cylinder 4 in a said left side and right free cylinder 5 is equipped with scrambler 11 respectively, between said left head roll 2 and the left free cylinder 4 left lifting jack 6 is housed, and between said right head roll 3 and the right free cylinder 5 right lifting jack 7 is housed.
The Automobile Anti-lock Braking parts of the utility model and the principle of work of system performance verifying attachment are following:
1, the ABS parts detect:
Like Fig. 1, shown in 2; Verifying attachment driven by automobile, and two automotive wheels 1 fall into respectively between left head roll 2 and left free cylinder 4, right head roll 3 and the right free cylinder 5, fall left lifting jack 6; Under frequency modulation motor 8 drives; Head roll 2 driving automobile wheels 1 in a left side rotate, and when reaching detection speed (5km/h), carry out the wheel speed sensors duty test of automotive wheel 1; Gently step on automobile brake pedal, automotive wheel 1 is braked, and damping force acts on the left head roll 2, detects the duty of automobile ABS pump, valve through the dtc signal that reads torque sensor 9.
Control left lifting jack 6 lifting automotive wheels 1 itself and left head roll 2 are disengaged, can test the opposite side wheel speed sensors, the performance of parts such as operation valve realizes that each parts of automobile ABS detect respectively.
2, the dynamic slip rate of automotive wheel detects:
Like Fig. 1, shown in 2, check-out console driven by automobile, and automotive wheel 1 falls between left head roll 2, right head roll 3 and left free cylinder 4, the right free cylinder 5; Fall left lifting jack 6 and right lifting jack 7; Under frequency modulation motor 8 drove, left and right driving cylinder driving automobile wheel 1 rotated, and automotive wheel 1 drives left and right free cylinder 6 and rotates; Step on down automobile brake pedal when reaching detection speed (40km/h) fast; Automotive wheel 1 is braked, and the rotating speed of control frequency modulation motor 8 is under the synergy of flywheel 10 and frequency modulation motor 8; Make the retarded velocity in retarded velocity simulated automotive when braking of the cylindrical of left and right driving cylinder, this velocity amplitude records through torque sensor 9 in real time; Automotive wheel 1 drives left and right free cylinder and rotates, and the real-time rotating speed of automotive wheel 1 can accurately record through the scrambler 11 on the left and right free cylinder in real time.Torque sensor 9 on the left and right driving cylinder has recorded the real-time speed of a motor vehicle, and the scrambler 11 on the left and right free cylinder has recorded the real-time speed of taking turns, and can try to achieve the dynamic slip rate of automotive wheel in the anti-lock brake process through the calculating of these two measured values.
The Automobile Anti-lock Braking parts of the utility model and the advantage of system performance verifying attachment are following:
1), realized that the performance test of automobile ABS parts and system performance testing accomplish on a verifying attachment through the one-sided control of lifting jack and install torque sensor additional and satisfied performance test requirement to the automobile ABS parts.
2) adopt single head roll to drive automotive wheel; Free cylinder upper support power does not produce braking moment; Only effect has vehicle wheel braking force on head roll; Opplied moment to cylinder during automobile brake reduces greatly, thereby can adopt the motor of smaller power and the flywheel of less moment of inertia during the time history when utilizing frequency modulation motor and flywheel combined simulation automobile brake.
3) the utility model has not only solved in daily Automobile Detection; Realize detecting the anti-problem of embracing the function quantizating index of this anti-lock braking system(ABS) of slip rate; And can detect index of correlation such as anti-locking system operating frequency, thereby judge the whether in proper working order and anti-control of quality of embracing of anti-block braking system of car.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
