Abstract
A maintenance-free axle belongs to axles of automobiles and particularly relates to axles of semi-trailers. The maintenance-free axle comprises a shaft, a bearing, a brake bottom plate, a hub, a hub cover, an oil seal, a cam shaft, an adjusting arm, a drum brake and a brake shoe assembly which are connected, and is characterized in that the hub cover is provided with an oil filling hole, liquid lubricating grease is injected from a feed hole, a transparent observation window is arranged at one end of the hub cover, and the adjusting arm is provided with an automatic gap adjusting arm. The maintenance-free axle has the advantages that the bearing of the axle is lubricated by the liquid lubricating grease, and brake gaps are automatically adjusted, so that maintenance of the bearing of the axle and the brake gaps can be omitted, and oil filling and brake gap adjustment is convenient and fast. Besides, the service life of the bearing is prolonged, consumption is reduced, time and cost for repair and maintenance are reduced, brake failure is avoided and driving safety is guaranteed. The maintenance-free axle is applicable to various types of axles of the semi-trailers.
Description
Technical field
The utility model relates to a kind of superimposed trailer vehicle bridge.
Background technology
Vehicle bridge on the automobile often needs to be serviced when in use, maintains, and the place of its maintaining mainly concentrates on two positions: the one, and bearing and grease thereof, the method for maintenance is to open wheel hub, brake wheel, changes the grease on the bearing; The 2nd, the adjustment braking gap after using a period of time, all need be adjusted braking gap when friction disc wear attenuation, brake are sensitive inadequately, and method is to get into below the vehicle bridge with the adjustable bolt of special wrench rotation adjusting arm, changes the angle of adjusting arm.
It is loaded down with trivial details not to the utmost that grease is especially changed in the maintenance at these two positions; Work capacity is big, and all requires certain technical ability, and it is pretty troublesome to open the wheel hub brake wheel; All might burn bearing if the gap of bearing is bigger than normal or less than normal when installing, also burn tires when temperature is high even cause fire! Braking gap is adjusted improper meeting and is caused brake locking or brake failure, the safety of serious threat driving.Because vehicle bridge care work amount is big, technical requirements is high, therefore many chaufeurs oneself can not maintain, and the maintenance station of need driving could be accomplished maintenance, both wastes time, and has improved cost again.
Summary of the invention
The purpose of the utility model provides a kind of non-maintaining vehicle bridge, solves the bearing lubrication and the brake facing gap of vehicle bridge, and oiling and adjustment braking gap are convenient, fast, reduce service time, reduces consuming guarantee driving safety.
Non-maintaining vehicle bridge; Comprise axis body, bearing, back-plate, wheel hub, wheel hub cover, oil sealing, camshaft, adjusting arm, brake wheel and brake shoe assembly; Be characterized in: described wheel hub cover is provided with filler port; Liquid lubricating oil injects by adding hand-hole, and transparent observation window is established in the end of wheel hub cover, observes lubricants capacity; Described adjusting arm configuration automatic play compensation arm, the braking gap automatic compensation.
Liquid lubricating oil injects around the bearing in the wheel hub through the filler port on the wheel hub cover, has better lubricated, cooling-down effect, can avoid bearing running hot, prolongs the service life of bearing.But wheel hub cover and oil sealed sealing property are required to increase.Wheel hub cover is provided with transparent observation window, by vitreous glazing/plastic material sealing.Need not to open wheel hub, brake wheel and just can see bearing lubrication state on every side; A need is opened additional the getting final product of the direct oiling of little nut on the pouring orifice if oil mass is on the low side, can practice thrift great deal of labor, and is very convenient, quick; Can not change the gap of bearing, not only economy but also safety yet.
The utility model is provided with automatic reglation arm for braking gap; The automatic compensation arm can be worked according to the gap perception principle; When braking gap constantly increases along with ferrodo wearing and tearing when this gap reaches the dangerous gap when needing hand adjustment; It can be adjusted automatically, thereby guarantees at the braking gap between shoe plate and brake wheel to have solved trouble and because the problem of the adjustment untimely brake failure that cause of hand regulation arm because of manual work adjustment brake clearance all the time in normal interstice coverage.
The utility model compared with prior art, advantage is: can be with the liquid oil lubrication of vehicle bridge bearing, the automatic compensation braking gap is realized the non-maintaining of vehicle bridge bearing lubrication and braking gap, refuels and convenient, fast when adjusting braking gap; Prolong bearing service life, reduce consuming, reduce maintaining time and expense; Avoid brake failure, guarantee driving safety.
Description of drawings
Fig. 1 is the structural representation of non-maintaining vehicle bridge.
Fig. 2 is the local left view that amplifies of the wheel hub cover of this Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2; Non-maintaining vehicle bridge comprises that axis body 8, wheel hub cover 1, bearing 2, wheel hub 3, brake wheel 4, oil sealing 5, back-plate 7, adjusting arm 9 and brake shoe assembly 6 connect and compose; Wheel hub cover 1 is provided with filler port 11; Liquid lubricating oil injects by adding hand-hole, and vitreous glazing leak free observation window 10 is established in the end of wheel hub cover 1, observes the lubricating oil oil mass.Adjusting arm configuration automatic compensation arm, the automatic compensation braking gap.Use this vehicle bridge to avoid demolition and maintenance, avoid the manual work adjustment of braking gap, thereby realize the non-maintaining of vehicle bridge.
Claims (2)
1. non-maintaining vehicle bridge; Comprise that axis body (8), wheel hub cover (1), bearing (2), wheel hub (3), brake wheel (4), oil sealing (5), back-plate (7), adjusting arm (9) and brake shoe assembly (6) connect and compose; It is characterized in that: establish filler port (11) on the wheel hub cover (1); Liquid lubricating oil injects by adding hand-hole, and transparent observation window (10) is established in the end of wheel hub cover (1), observes the lubricating oil oil mass; Adjusting arm (9) configuration automatic play compensation arm, the automatic compensation braking gap.
