Abstract
The utility model belongs to the technical field of a spare wheel rack of an automobile tire. The spare wheel rack of an automobile tire is composed of a bracket of the spare wheel rack, a driving device, and a rocking handle. The driving device of the utility model is a tooth differential driving device. The bracket of the spare wheel rack has an integrative structure and is used for fixing a spare tire of an automobile. The utility model has the advantages of high productive efficiency, convenient utilization, safety, low failure rate, and self-locking action.
Description
(1) technical field
The utility model belongs to the technical field of motor tire spare wheel holder.
(2) background technology
The side spare wheel holder that present homemade heavy motor vehicle uses, its driving device are basically based on the worm and gear transmission, and this installs productive costs height, and production efficiency is low, poor stability during dismounting, and the worm and gear material requested is good, and the fault rate height.
(3) summary of the invention
The purpose of this utility model is to provide a kind of production efficiency height, safety easy to use, and fault rate is low, has the motor tire spare wheel holder of self-locking action.
The purpose of this utility model is achieved in that
The motor tire spare wheel holder is made up of spare wheel holder support driving device rocking handle, and driving device of the present utility model is a tooth difference driving device.
Further improvement of the present utility model is that the spare wheel holder support is made one-piece construction.
Because the characteristic of side one tooth difference spare wheel holder, it is compared with the side spare wheel holder of worm and gear transmission following advantage is arranged: 1. productive costs is low: the production of worm and gear device needs specialized equipments such as gear hobbing, complex process, technical requirements height, material therefor are alloy steel, so the cost height, one tooth difference driving device is a precision castings, need not specialized equipment, technology is simple, uses general steel; 2. has self-locking action: after this device is promoted to desired location with tire, can keep original position motionless after letting go; 3. safety: because side one tooth difference spare wheel holder self-locking action improved safety during dismounting, and the side spare wheel holder of worm and gear transmission does not possess these characteristics; 4. production efficiency height; 5. easy to use; The spare wheel holder rocking handle of this device can put it in the automobile toolbox when not using; 6. fault rate is low: this appliance stand adopts one-piece construction, and its side spare wheel holder is welded by steel plate; 7. it is good to assemble commonality: this device mounting hole site is identical with other side spare wheel holder.
Therefore, the utlity model has the production efficiency height, safety easy to use, fault rate is low, has the advantage of self-locking action.
(4) description of drawings
As figure is structural representation of the present utility model
Among the figure, 1. hexagonal bar iron, 2. self lock nut, 3. wheel nut, a 4. tooth difference driving device, 5. rocking handle, 6. spare wheel holder support, 7. hexagonal bar iron, 8. spring washer, 9. hexagonal nut, 10. chassis side rail, 11. spare tyres
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Spare wheel holder support 6 usefulness hexagonal bar irons 1 and self lock nut 2 are fixed on the chassis side rail 10, one tooth difference driving device, 4 usefulness hexagonal bar irons, 7 spring washers, 8 hexagonal nuts are fixed on the spare tyre holder support 6, after on the one tooth difference driving device 4 rocking handle 5 being installed, by the rotation of rocking handle, spare tyre can be fixed on the spare wheel holder support.
Claims (2)
1. a motor tire spare wheel holder is made up of spare wheel holder support driving device rocking handle, it is characterized in that: driving device is a tooth difference driving device.
2. motor tire spare wheel holder according to claim 1 is characterized in that: the spare wheel holder support is an one-piece construction.
