Description
Technical field
The present invention relates to speed measuring device, more particularly to vehicle speed measuring device, specially test the speed wheeled support device.
Background technology
Roller-type speed measurement device is a kind of common vehicle speed measuring device, and it mainly includes fifth wheel, bracket component, stretches
Bar and velocity sensor, wherein bracket component include support frame and fixed cover, and fifth wheel is supported on support frame, and fixed cover is fixed
In bottom of frame, support frame is connected with fixed cover by expansion link.Although expansion link is flexible along fixed cover axial elasticity, so as to have
There is certain cushioning effect, and when causing that fifth wheel is close to road surface, but fifth wheel by rugged road surface, expansion link bears
Larger stress, is easily bent, and causes expansion link to engage with fixed cover, and influence is normally tested the speed.
The content of the invention
Regarding to the issue above, the invention provides the wheeled support device that tests the speed, its can solve in the prior art expansion link easily with
Fixed cover engages, the normal technical problem for testing the speed of influence.
Its technical scheme is such, and it includes car body connecting seat, test the speed wheel support and spring, it is characterised in that：
The car body connecting seat include pedestal, guide pad and connecting plate, the guide pad be fixed on the pedestal bottom and downwards
Guide part is convexly equipped with, the guide part has the indent spigot surface of circular arc and the chute of the circular arc extended along spigot surface,
The lower ending opening closing of the chute, a pair of connecting plates be distributed in the both sides in the trough width direction and with the guide pad
It is fixedly connected；
The upper-end part of driving of the wheel support that tests the speed is stretched into the cell body enclosed by guide pad, connecting plate and by rotating shaft and both sides
Connecting plate is pivotally connected, and the evagination spigot surface of circular arc is provided with the top of the wheel support that tests the speed and evagination spigot surface is arranged at
The sliding block of middle part, the evagination spigot surface coordinates with the indent spigot surface, and the sliding block is slidably connected to the chute
It is interior；
The spring is arranged at the closing portion that the chute is interior, its two ends bears against the sliding block and the chute lower end.
Further, the section of the chute and the sliding block is T-shaped.
Further, the lower ending opening of the chute is closed by shrouding, and the shrouding is fixedly connected with the guide part.
Further, the spring is helical spring.
Support meanss of the invention, fifth wheel is fixed on the lower end part of the wheel support that tests the speed, the upper-end part of driving of fifth wheel
Stretch into the cell body enclosed by guide pad, connecting plate and be pivotally connected with two side connecting plates by rotating shaft, when fifth wheel is through too high
During low uneven road surface, the vertically movable drive of fifth wheel is tested the speed being pivoted of wheel support, meanwhile, it is arranged at the bullet in chute
Spring against fifth wheel cradle top sliding block, with the anglec of rotation of limit bracket so that fifth wheel is close to bottom surface；Due to fifth wheel
Support can adapt to road surface and be swung, and not only suffered stress is smaller, and be not in stuck phenomenon.
