Abstract
The invention provides a wheel hub bearing unit with an adjustable windage. The unit comprises two bearings, a flange plate and a snap ring, wherein the snap ring is fixedly pressed and arranged in the flange plate, a pressure induction piece is arranged on the interior of two bearings, an annular hydraulic device is arranged between two bearing outer rings, a temperature and pressure induction device is additionally arranged on the exterior of the hydraulic device and connected with the exterior of a car through an induction piece wiring; when the temperature and the pressure reach set values, the outer rings of two bearings are translocated to the middle, the windage of the bearings is enlarged, otherwise, the windage of the bearings is narrowed, so that the working of the wheel hub bearing unit in a set windage range is ensured, the service life of the wheel hub bearing is prolonged, and the safe reliability is improved.
Description
Technical field
The present invention relates to a kind of hub-bearing unit, the adjustable hub-bearing unit of especially a kind of play.
Background technique
Now, Freight Transport is more and more important, and transport power is also increasing, and vehicle increases swift and violent, also becomes more and more important as the hub bearing of one of lorry safety component.Country truck hub bearing working life by ten thousand kilometers of 200,000 kilometers speed-raisings to 50 (developed country even bring up to 1,000,000 kilometers), reliability requirement reaches 99%, proposes as a kind of strong basis project.
Freight car bearing is bigger because of bearing load, and stream time is long, so bearing heats up easily, thereby bearing clearance is reduced, and prefastening load strengthens, and makes pivot friction power strengthen, and has aggravated bearing temperature rise.On the other hand, truckload is bigger, and brake control power is bigger, like this when brake, can sharply rub with brake block, produce moment high temperature, the wheel hub temperature is sharply risen, make bearing temperature rise higher, may make rolling element and the lasso of bearing inside take place bonding, make bearing failure, bearing even meeting locking produce serious consequence when serious.
Summary of the invention
For solving the problem that existing hub bearing exists, prolong the working life of hub bearing, improve safety reliability, the invention provides the adjustable hub-bearing unit of a kind of play, in the middle of two row bearing outer rings, set up annular hydraulic pressure installation, outside reload temperature and pressure sensitive device at hydraulic pressure installation are connected with automobile external by the induction piece wiring.When temperature and pressure reached setting value, the outer ring of two row bearings was shifted to the centre, increased bearing clearance, and when temperature and pressure during less than setting value, the outer ring of two row bearings is shifted to both sides, reduces bearing clearance.
For realizing above-mentioned purpose, technological scheme of the present invention is: the hub-bearing unit that play is adjustable comprises two bearings, flange plate and snap rings; Two bearing inside the pressure sensitive sheet is installed, snap ring fixedly is fitted in the flange plate, is provided with annular hydraulic pressure installation in the middle of two row bearing outer rings, and outside reload temperature and pressure sensitive device at hydraulic pressure installation are connected with automobile external by the induction piece wiring.When the pressure and temperature of temperature and pressure induction installation reaches setting value, the oil inlet pipe relief valve is opened, oil pressure reduces, the pressure of hydraulic pressure installation reduces, thrust reduces, and the outer ring of two row bearings is shifted to the centre, thereby increases bearing clearance, otherwise then reduce play, thereby the assurance hub-bearing unit is worked in the play scope of setting.
Description of drawings
Fig. 1 is the adjustable hub-bearing unit structural representation of play.
Among the figure: 1. inner ring, 2, retainer, 3, seal ring, 4, the outer ring, 5, oil pump, 6, the pressure sensitive sheet, 7, roller, 8, snap ring, 9, flange plate, 10, oil inlet pipe, 11, oil outlet tube, 12 induction piece wiring.
Embodiment
As shown in Figure 1, the hub-bearing unit that play is adjustable comprises two single row bearings, flange plate (9) and snap ring (8); Single row bearing comprises inner ring (1), retainer (2), seal ring (3), outer ring (4) and roller (7), two single row bearing inside pressure sensitive sheet (6) is installed, snap ring is fixedly mounted in the flange plate, in the middle of two row bearing outer rings, be provided with annular hydraulic fluid pump (5), oil pump is provided with oil inlet pipe (10) and oil outlet tube (11), outside reload temperature and pressure sensitive device at hydraulic-pressure pump are connected with automobile external by induction piece wiring (12).In use, when the pressure and temperature of temperature and pressure induction installation reached setting value, the oil inlet pipe relief valve was opened, oil pressure reduces, the pressure of hydraulic pressure installation reduces, and thrust reduces, and the outer ring of two row bearings is shifted to the centre, thereby increase bearing clearance, when temperature and pressure during less than setting value, the outer ring of two row bearings is shifted to both sides, reduces bearing clearance, thereby the assurance hub-bearing unit is worked in the play scope of setting, and reaches the long lifetime of bearing and the purpose of safety reliability.
Claims (2)
1. the adjustable hub-bearing unit of play, comprise two bearings, flange plate and snap rings, snap ring fixedly is fitted in the flange plate, it is characterized in that, two bearing inside the pressure sensitive sheet is installed, in the middle of two bearing outer rings, be provided with annular hydraulic pressure installation, in the outside of hydraulic pressure installation the temperature and pressure induction installation be housed, be connected with automobile external by the induction piece wiring; When temperature and pressure reached setting value, the oil inlet pipe relief valve was opened, and oil pressure reduces, and the pressure of hydraulic pressure installation reduces, and thrust reduces, and the outer ring of two row bearings is shifted to the centre, increased bearing clearance; When temperature and pressure during less than setting value, the outer ring of two row bearings is shifted to both sides, reduces bearing clearance.
2. the adjustable hub-bearing unit of play as claimed in claim 1 is characterized in that, described bearing is single row bearing, and described hydraulic pressure installation is oil pump.
