Abstract
The utility model relates to a safety device for a bearing of a rear axle shaft of a mini car, which is composed of an axle shaft (1), bearings (2), an oil storage isolating ring (3), a bearing axle housing (4) and an oil nipple (5). Double bearings (2) are installed at two ends of the rear axle shaft (1) to reduce load and strong impact to the bearings (2) so as to prolong service life of the bearings (2). The oil storage isolation ring (3) with an outer diameter smaller than that of the bearings (2) is installed between the bearings (2) to form a clearance which is between the double bearings (2) used for feeding and storing lubricating oil. The oil nipple (5) on the bearing axle housing (4) is used for replenishing new lubricating oil to the oil storage isolation ring (3) and the bearings (2) so as to effectively overcome failures caused by lubricating oil shortage in the bearings (2). Therefore, potential safety hazards of accidents of vehicles caused by damages of the bearings (2) at two ends of the rear axle shaft (1) are effectively avoided.
Description
(1) technical field
The utility model belongs to the mid-get car transmission, and actuation techniques is specifically related to the bearing arrangement at the back axle jackshaft two ends of mid-get car.
(2) technical background
The bearing of existing mid-get car back axle jackshaft, adopt the semiaxis two ends that a bearing respectively is installed mostly and bear carload, lubricating oil in the bearing all is disposable packing into, when long lubricating oil of time exhausts or aging, vehicle is damaged at the operational process centre bearer can not cruising, also because of a bearing capacity deficiency, when often meeting the road conditions difference, a bearing occurs and be damaged by powerful the impact, cause the vehicle burst accident to happen occasionally.
(3) summary of the invention
The purpose of this utility model is at the prior art above shortcomings, a kind of mid-get car rear axle shaft bearing safety device is provided, efficiently solve the bearing necrosis that lacks or wear out and cause because of lubricating oil, also can effectively solve bearing capacity, improve the service life of bearing, reduce the vehicle burst accident.
The technical solution of the utility model is as follows:
A kind of mid-get car rear axle shaft bearing safety device, comprise semiaxis, bearing more than two or two is provided with the oil storage shading ring made from metal or plastics less than bearing outside diameter between bearing and the bearing, the bearing axle housing is provided with the oil nipple that adds lubricating oil to bearing.After the bearing more than two or two that the oil storage shading ring made with metal or plastics separates is respectively loaded onto at automobile axle jackshaft two ends, the load of automobile and strong impact force just bear the bearing that becomes more than two or two by an original bearing and share, thereby alleviated the stressed of bearing, the probability of bearing necrosis reduces, when
A bearing necrosis, other bearing can also normally use, and reduces the vehicle burst accident.
The oil storage shading ring made from metal or plastics less than bearing outside diameter is housed between bearing and the bearing simultaneously, form the gap between the bearing more than two or two, the space in gap adds and the deposit lubricating oil, by the oil nipple on the bearing axle housing, replenish new lubricating oil for oil storage shading ring and bearing, solved effectively that the bearing internal cause lacks lubricating oil and the fault that produces.Thereby prevented that better vehicle from bringing the potential safety hazard of burst accident because of the bearing necrosis at rear axle shaft two ends.
The bearing more than two or two has been adopted at the utility model rear axle shaft two ends, be provided with the oil storage shading ring made from metal or plastics between bearing and the bearing less than bearing outside diameter, the bearing axle housing is provided with the mode of oil nipple, simple in structure, alleviated the stressed of bearing, oil nipple on the bearing axle housing can replenish the lubricating oil of bearing effectively, improved bearing service life, a bearing necrosis, other bearing can also normally use, thereby reduces because of the downright bad suddenly burst car accident of bearing.Therefore have good economic benefits and practical value.
(4) description of drawings
Fig. 1 is a kind of mid-get car rear axle shaft bearing safety device structural representation.
Among the figure: 1. semiaxis, 2. bearing, 3. oil storage shading ring, 4 bearing axle housing, 5. oil nipples
The specific embodiment:
Referring to Fig. 1, a kind of mid-get car rear axle shaft bearing safety device, the two ends that comprise semiaxis 1 respectively are provided with the bearing 2 more than two or two, are provided with the oil storage shading ring made from metal or plastics 3 less than bearing 2 external diameters between bearing 2 and the bearing 2, and bearing axle housing 4 is provided with oil nipple 5.
A kind of mid-get car rear axle shaft of the utility model bearing safety device, it is the bearing 2 that respectively is provided with at the two ends of automobile axle jackshaft 1 more than two or two, the load of automobile and strong impact force, just bearing the bearing 2 that becomes more than two or two by an original bearing 2 shares, thereby alleviated the stressed of bearing 2, improved the service life of bearing 2, bearing 2 necrosis, other bearing 2 can also normally use, thereby reduces because of the downright bad suddenly burst car accident of bearing 2.
The oil storage shading ring made from metal or plastics 3 less than bearing 2 external diameters is housed between bearing 2 and the bearing 2 simultaneously, forms the gap between the bearing 2 more than two or two, the space in gap adds and lays in lubricating oil.By the oil nipple 5 that is provided with on the bearing axle housing 4, replenish new lubricating oils for oil storage shading ring 3 and bearing 2, solved effectively that bearing 2 internal causes lack lubricating oil and the fault that produces.Thereby prevented that better vehicle from bringing the potential safety hazard of burst accident because of bearing 2 necrosis at rear axle shaft 1 two ends.
