Abstract
The utility model discloses a movable automobile brake detector, which relates to the automobile brake testing aspect. The movable automobile brake detector is composed of a roller system, a weighing system and a force measuring system. The movable automobile brake detector is characterized in that the force measuring system is that a plunger piston hydraulic force measuring sensor drives a chain to drive a roller to rotate. The device solves the unreasonable problem that roadway judgment is often adopted in automobile repair industry; the utility model not only reduces the phenomenon that tires are badly worn, but also provides a movable convenient brake power testing tool for the automobile repair industry.
Description
The utility model is the invention about the automobile brake aspect, more specifically says it is to have and detect the whether mobile automobile braking detector of standard of brake device for car under the doughnut situation about detecting the neutralization of particularly auto repair process of automobile brake perfrmance.
At present, the test to automobile brake perfrmance in the motor vehicle repair process tries to judge that the road examination detects the restriction that both had been subjected to pavement behavior by the road, and judges that trueness error is big, and it is serious to produce tire wear again, wastes big phenomenon.Existing fifth wheel instrument and deceleration of electrons tester all do not fit in the automobile brake repair procedures tests damping force, a lot of vehicles do not reach the standard that requires because of the damping force test when therefore examining annually, the detection line of getting on the car again after needing to repair again, the appearance repeatedly of this situation, not only wasted servicing time, and economic waste is very big.The automotive performance detection line both had been subjected to the restriction of fixed venue, and investment is bigger, and therefore general medium and small Auto repair shop can't improve detection level, has also hindered the raising of motor vehicle repair assurance of conformity rate.
The purpose of this utility model is to provide a kind of conveniently moving, test the detector of mobile automobile braking accurately, this instrument can move to the position of the required detection of each vehicle easily, has both improved work efficiency, reduced tire wear again, guaranteed that automobile brake perfrmance reaches criterion of acceptability.
Task of the present utility model is achieved in that
A kind of mobile automobile braking detector, it is made up of roller system, weighing system, dynamometric system, it is characterized in that dynamometric system is to drive cylinder (11) rotation by plunger hydraulic force cell (18) chain drive-belt (15); The best form of mobile automobile braking detector can be that weighing system is made up of weighing plate (20) and plunger hydraulic force cell (19); The best form of mobile automobile brake tester also can be that plunger hydraulic force cell (18) is fixedlyed connected with commutator (17), and chain (15) is embedded in the commutator (17); Commutator (17) can be made up of with the slide plate of fixedlying connected (26), plate (28) guide plate (27), eccentric block (23) is arranged in the hole (24) of slide plate (26), rotate eccentric block (23) and can drive slide plate (26) move left and right, thereby change the direction of motion of chain (15).When plunger hydraulic force cell (18) is mobile, can pass through chain (15) and drive cylinder (11) rotation, cylinder (11) will act on plunger hydraulic force cell (18) with the reacting force of tire friction, so just can measure the automobile braking force that this is taken turns easily.
Advantage of the present utility model is that this invention is simple in structure, volume is little, conveniently moving, when need testing automobile damping force, can easily mobile automobile be braked detector and move to the vehicle next door, it is heavy to measure automobile braking force and raise, reduce the wearing and tearing of doughnut, provide reliable means of testing for guaranteeing the auto repair quality.
Accompanying drawing has been described an embodiment of the present utility model.
Fig. 1: the structural representation of portable vehicle braking detector.
Fig. 2: the front view of commutator.
Fig. 3: the vertical view of commutator.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail:
When using the utility model detection automobile braking force, it is middle at first to drive car into two cylinders (11) through the extradition plate, cylinder (11) is by bearing seat (9) supporting, tire is pressed on two cylinders (11), plunger hydraulic force cell (19) is set between two cylinders, weighing plate (20) is set (19), and sensor (19) is by linking arm (12) and frame (21) hinge joint.The switch (6) of opening plunger hydraulic pressure force cell (19), off switch (8), tighten oil return valve (10), press press rods (7) up and down, oil pump (2) to-and-fro movement is with in the oil cylinder of the oil of the medium in the fuel tank (1) by petroleum pipeline (3), variable valve (5) input plunger hydraulic force cell (19), thereby promoting plunger moves upward tire jack-up, tire stops to press oil pump when leaving two cylinders (11), show that by sensor feedback numerical value is this and takes turns weight this moment.Unclamp oil return valve (10), the own wt of wheel pushes back the plunger of plunger hydraulic force cell in the oil cylinder, and tire is pressed in again on two cylinders (11).Commutator (17) is made up of guide plate (27), slide plate (26) and plate (28), slide plate (26) is fixedlyed connected with plate (28) by bolt, eccentric block (23) is arranged in the hole (24) of slide plate (26), and be connected with guide plate (27) by handle (25), turning handle (25) drives eccentric block (23) and rotates, thereby drive slide plate (26) along guide plate (27) move left and right, impel plate (28) to insert in the hole (22) of the gap of chain (15) and guide plate (27).Fixedlying connected with guide plate (27) by screw in the upper end of plunger hydraulic force cell (18), impels commutator (17) and sensor (18) to be synchronized with the movement, and the lower end is fixed on the support (21).
When testing automobile damping force, at first close the switch (6) on the variable valve (5), open the switch (8) of plunger hydraulic force cell (18), tighten oil return valve (10), turning handle (25) is selected the direction of motion of chain (15), press press rods (7), driving oil pump (2) imports in the oil cylinder of plunger hydraulic force cell (18) medium oil, oil cylinder moves upward and drives commutator (17) drive chain (15) motion, chain (15) drives cylinder (11) and rotates, when driving the tire rotation direction, cylinder (11) depresses automobile brake pedal when direction is consistent to overtake with automobile, and make detent be in maximum on-position, continue to press press rods (7), chain (15) is by sprocket wheel (13), (14), (16) head roll (11) rotates, the reacting force that obtains during cylinder (11) tire on the drive wheels shows that by the plunger hydraulic force cell when numerical value no longer increased, this value was this maximum braking force of taking turns.
Unclamp oil return valve (10), the oil pressure release.Need when detecting the another side wheel tester is moved, commutator (17) is pushed the opposite location positioning instant can.Heavy and the damping force with the raise that can measure each wheel with quadrat method.One end of cylinder (11) is by sliding bearing (9) supporting, and the other end is rotated by support (21) supporting between sprocket wheel (13), (14) by support (21) supporting.Sprocket wheel (16) is fixed on the drum shaft, and two cylinders link into an integrated entity by bearing seat (9) and base plate (4).
