Abstract
A kind of brake and drive system for vehicle with tow master cylinder idle stroke detection table of car, belongs to detection means manufacturing technology field, and it is made up of oil supply system, drive system and detecting system, and oil supply system includes fuel tank, oil inlet pipe, oil pump, flow sensor and oil return pipe；Drive system includes frame, motor, screw mandrel, screw, linear bearing, push rod, load plate and displacement transducer；Detecting system includes processor and display, and processor connects displacement transducer and flow sensor respectively.The oil inlet pipe other end is connected to the oil-out of cylinder body during detection, the oil return pipe other end is connected to the oil inlet of cylinder body, start oil pump, oil in fuel tank circulates by flow sensor, restart motor, push rod makes valve rod promote piston valve movement, support plate drives the telescopic head of displacement transducer to stretch out simultaneously, when piston valve closes oil inlet, oil in oil supply system stops flowing, processor receives the information that displacement transducer and flow sensor are sent, so as to judge distance of the piston valve from initial position to oil inlet, that is, idle stroke.The utility model accuracy of detection is high, speed is fast, device structure advantages of simple.
Description
Technical field：
The utility model belongs to detection means manufacturing technology field, is a kind of brake system idle stroke detection device.
Background technology：
Brake and drive system for vehicle with tow master cylinder is mainly made up of cylinder body, valve rod and piston valve, and oil inlet and fuel-displaced is provided with cylinder body
Mouthful, there is brake fluid in cylinder body.When needing brake, valve rod promotes piston valve, living because oil inlet is open mode during beginning
Brake fluid in cylinder body is pushed outwardly by obturator valve from oil inlet, does not have pressure in cylinder body, when piston valve continue to be forwarded into
During oil port, oil inlet is closed, there is pressure in cylinder body, the brake fluid in cylinder body is pushed out from oil-out, and control is braked
Piece movement is braked.From initial position, this section of stroke at oil inlet does not act piston valve to vehicle braking, claims this
Duan Hangcheng is idle stroke.The length of idle stroke is very big on brake system influence, and idle stroke is long, causes brake reaction slow, may
There is driving accident.The detection of brake system idle stroke at present typically uses mechanical system artificial detection, and accuracy is low, work effect
Rate is low.
The content of the invention：
The technical problems to be solved in the utility model is to disclose a kind of brake and drive system for vehicle with tow master cylinder idle stroke detection table of car, so as to
Idle stroke can be accurately detected.
The scheme that the utility model solves technical problem is to form vehicle using oil supply system, drive system and detecting system
Brake system master cylinder idle stroke detection table of car, oil supply system include fuel tank, oil inlet pipe, oil pump, flow sensor and oil return pipe, oil-feed
Pipe connects fuel tank, and oil pump and flow sensor are arranged on oil inlet pipe, oil return pipe connection fuel tank；Drive system includes frame, electricity
Machine, coupling sleeve, bearing block, screw mandrel, screw, linear bearing, push rod, load plate and displacement transducer, motor are arranged under frame
The outside of frame, bearing block are fixed in frame, and screw mandrel is arranged on bearing block, and screw mandrel bottom connects the defeated of motor by coupling sleeve
Shaft, the screw mandrel on bearing block top are cased with screw, and linear bearing is arranged at frame upper ledge, and push rod is arranged on linear bearing,
Push rod bottom connects load plate, load plate connection screw, and displacement transducer is fixed at frame lower frame, load plate and displacement sensing
Device is connected；Detecting system includes processor and display, and processor connects displacement transducer and flow sensor respectively, shows
Show that device connects processor.The oil inlet pipe other end is connected on the oil-out of cylinder body during detection, the oil return pipe other end is connected to cylinder
On the oil inlet of body, start oil pump, the oil in fuel tank returns to fuel tank by oil inlet pipe, inner chamber of cylinder block and oil return pipe, now flow
Sensor has oil stream mistake, restarts motor, drives screw mandrel to rotate, and screw is moved upwards along screw mandrel, and push rod is driven by load plate
Motion upwards, valve rod is set to promote piston valve movement, while support plate drives the telescopic head of displacement transducer to stretch out, and works as piston valve
When oil inlet is closed, the oil in oil supply system stops flowing, and flow sensor does not have oil stream mistake, and processor receives displacement biography
The information that sensor and flow sensor are sent, so as to judge distance of the piston valve from initial position to oil inlet, that is,
Idle stroke, flow sensor send the information that no oil stream is crossed, and illustrate that piston valve reaches oil inlet position, display receiving area
The signal of device is managed, and is shown.
Cylinder is installed between push rod bottom and load plate, the initial position of load plate can be adjusted by cylinder, is made
Obtain piston valve initial position zero.
The utility model accuracy of detection is high, speed is fast, device structure advantages of simple.
