Problems solved by technology

[0005] Then the inventor carried out a driving test and a real vehicle collision test with a mileage of more than 100,000 kilometers in one year, and found that the inventor's patent number is: "a small bearing with low speed and special ability to withstand heavy pressure" still exists The following deficiencies: due to the poor dustproof performance, the small heavy-duty bearing in the seat has been inflexible in just one year; The bearing on the shaft is also due to the limitation of space, and the thinner outer ring of the bearing also has a certain permanent deformation, so that the outer ring of the bearing cannot rotate

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] In a normal state, the oil storage tanks 4 and 4` are filled with lubricating oil and the roller outer ring 5 with dust-proof oil seals at both ends is placed on the roller inner ring 7 through the axial inner circle 9 on the ring, and the roller shaft 6 is placed on the In the inner circle of the roller inner ring 7.

[0025] When a car has a serious collision accident, the lower surface of the special roller outer ring 5 of the special seat in the front row of the car will be subjected to a frictional force, and the inner and outer rings of the roller are lubricated by lubricating oil. The outer ring 5 will rotate around the roller shaft 6, turning the large sliding friction into a small rolling friction. At this time, the special seat in the front row of the car will move briskly to the rear safety zone, so that the front row drivers...

Abstract

The roller specially for front row chair in automobile has an inner ring and an outer ring of 45+ / -15# steel. The outer ring has oil sumps in the ends with oil seal, and the inner ring is inserted into the oil sumps filled with lubricating oil directly without need of balls or needle roller. In case of collision of automobile, the outer ring is rotated by the friction force, and the sliding friction is changed into rolling friction, so that the special chair moves backwards lightly to avoid the injury of the rider.

Description

technical field [0001] The invention relates to a bearing, especially a special roller for a special seat in the front row of an automobile Background technique [0002] At present, there are many common bearings. In general, there are two types, one is ball bearings, and the other is roller (needle) bearings. Ball bearings have poor load capacity. Roller (needle) bearings can withstand heavy pressure. But now the common roller (needle) bearings in the market cannot be applied in places with special purposes. For example: I invented the "anti-extrusion car safety seat", the patent number is: 02240876.2. When an accident occurs in the car, the "anti-extrusion car safety seat" turns the original fixed seat into a seat that can move to the rear safety area, avoiding or reducing the direct damage to the driver caused by the deformed steering wheel and instrument panel. [0003] "Anti-extrusion car safety seat" requires two kinds of bearings: 1. The outer diameter of the bear...
