Description

Technical Field

[0001] This utility model relates to the field of tensioner technology, and more specifically, to a tensioner for automobiles with a double bearing structure. Background Technology

[0002] A tensioner pulley is a follower pulley pressed against the belt to change the wrap angle of the pulley or control the belt tension. It is a tensioning device for belt drives. When the center distance of the belt cannot be adjusted, a tensioner pulley can be used to tension the belt. The automotive tensioner assembly is mainly to ensure that the engine can correctly transmit energy to other components when it is working normally.

[0020] As attached Figure 1-4 As shown, this utility model provides a tensioning wheel for automobiles with a dual bearing structure, including a tensioning wheel body 1. An adjustment device 2 is provided at the rear end of the tensioning wheel body 1. The adjustment device 2 includes an angle adjustment component 21 and a length adjustment component 22. The rear end of the length adjustment component 22 is installed on the side of the angle adjustment component 21, and the front end of the length adjustment component 22 is installed at the rear end of the tensioning wheel body 1.

[0021] The angle adjustment assembly 21 includes: a rotating shaft 218, an adjusting shaft 213, a rotating adjustment handle 219, a fixed plate 211, an inner groove 216, and a first assembly screw hole 217. An assembly bolt 214 is detachably installed in the first assembly screw hole 217. The inner groove 216 is opened on the inner wall of the front end of the fixed plate 211. The output end of the rotating shaft 218 passes through the front and rear ends of the fixed plate 211. The front end of the fixed plate 211 is installed at the rear end of the adjusting shaft 213. The front and rear ends of the adjusting shaft 213 are provided with second assembly screw holes 215. The second assembly screw holes 215 and the first assembly screw hole 217 are compatible in size. The assembly bolt 214 is detachably installed inside the second assembly screw holes 215 and the first assembly screw hole 217. The front end of the rotating adjustment handle 219 is installed at the rear end of the rotating shaft 218. The size of the inner groove 216 is compatible with the size of the front and rear ends of the adjusting shaft 213. A positioning rod 212 is installed at the front end of the adjusting shaft 213.

[0022] The length adjustment assembly 22 includes: a rear positioning support rod 221, a front positioning support rod 225, a welding plate 226, an electric hydraulic cylinder 222, a placement platform 223, and a telescopic adjustment rod 224. The rear end of the telescopic adjustment rod 224 is installed at the front end of the rear positioning support rod 221, and the front end of the telescopic adjustment rod 224 is installed at the rear end of the front positioning support rod 225. The lower end of the electric hydraulic cylinder 222 is installed at the upper end of the placement platform 223. The inner outer wall of the placement platform 223 is installed on the outer side wall of the rear positioning support rod 221. The output end of the electric hydraulic cylinder 222 is installed at the rear end of the welding plate 226, and the outer side wall of the welding plate 226 is installed on the outer side wall of the front positioning support rod 225. The inner side of the rear end of the rear positioning support rod 221 is installed at the rear end of the positioning rod 212.

[0023] The specific implementation method is as follows: When using this utility model, if the length position of the tension wheel body 1 needs to be adjusted, the assembly bolt 214 can be removed, and the adjustment handle 219 can be rotated. After rotating the adjustment handle 219, the position of the positioning rod 212 installed at the front end will be adjusted. After rotating the positioning rod 212, the angle of the tension wheel body 1 and the length adjustment component 22 installed at the front end will be adjusted. After the tension wheel body 1 and the length adjustment component 22 are rotated upward to the position to be adjusted, the assembly bolt 214 can be assembled and fixed. After the assembly bolt 214 is assembled, the device can be started. The electric hydraulic cylinder 222, once started, drives the welding plate 226 and the front positioning support rod 225 mounted on the output end to move forward. After the front positioning support rod 225 moves forward, it pulls the telescopic adjustment rod 224 mounted on the rear end. After the telescopic adjustment rod 224 moves, the position of the tension wheel body 1 can be adjusted back and forth. This device greatly improves the adaptability of the entire device through simple rotation and telescopic adjustment, avoiding the need to replace the entire tension wheel equipment when the position and angle of the tension wheel need to be changed during use. This effectively improves the practicality and stability of the tension wheel body 1.

[0024] The working principle of this utility model is as follows: When the length of the tension wheel body 1 needs to be adjusted, the assembly bolt 214 can be removed, and the adjustment handle 219 can be rotated. After the adjustment handle 219 is rotated, the position of the positioning rod 212 installed at the front end will be adjusted. After the positioning rod 212 is rotated, the angle of the tension wheel body 1 and the length adjustment component 22 installed at the front end will be adjusted. After the tension wheel body 1 and the length adjustment component 22 are rotated upward to the position to be adjusted, the assembly bolt 214 is assembled and fixed. After the assembly bolt 214 is assembled, the electric hydraulic cylinder 222 is started. After starting, the welding plate 226 installed at the output end and the front positioning support rod 225 are moved forward. After the front positioning support rod 225 is moved forward, the telescopic adjustment rod 224 installed at the rear end is pulled. After the telescopic adjustment rod 224 is moved, the position of the tension wheel body 1 can be adjusted back and forth.
