Abstract
The utility model discloses a shock damping handle for walking tractors belonging to an operating mechanism of an agricultural transportation carrier, which is characterized in that a hand lever (8) is connected with a handle (1) through a connection shaft (2) provided with a vibration isolating rubber (4), so that the nonrigid connection between the hand lever (8) and the handle (1) can be realized. Consequently, the vibration of the hand lever transmitted by the vibration of machine body can be decreased and the operating conditions of the driver can be improved.
Description
The utility model belongs to a kind of steering unit of farm tractor.
Farm tractor, especially S195 type trac. is the main transportation means in China rural area, and except that the minority trac. adopted the disc type steering handle, most trac.s adopted " H " type handrail steering handle more, two handrail handles link to each other with body by two pipe links, and its connection mode is for being rigidly connected.Therefore, the vibration of driving engine passes to the handrail handle along pipe link by body, the oscillation frequency height, and Oscillation Amplitude and acceleration/accel are big, not only directly influence the control of tractor driver to direction, and the tractor driver is subjected to vibration effect for a long time, easily causes occupational disease in various degree, though, farm tractor has reached millions of at the consumption of China, and increase day by day, but the vibration problem of handrail steering handle but fails to attract much attention.
The purpose of this utility model provides a kind of vibration damping handrail handle of walker tractor, alleviates the influence of body vibration to steering handle, improves tractor driver's working environment.
Vibration damping handrail described in the utility model is connected with non-rigidity between the handrail handle by the handrail handle to realize being.Handrail handle and handrail between be connected by an adapter shaft, be with vibration isolation rubber circle and spacing sleeve on the adapter shaft alternately.Hold-down nut and jam nut make vibration isolation rubber circle radial growth, tensioner handrail in, thereby both realized that the handrail handle was connected with the non-rigid of handrail handle, guarantee that again it is connected with enough rigidity.
Detailed structure of the present utility model and embodiment be as shown in the figure:
Fig. 1. the vibration damping handrail is front elevation
1. handrail is 2. adapter shafts, 3. spacing sleeves, 4. vibration isolation rubbers, 5. hold-down nutes, 6. jam nuts, 7. handgrip adapter sleeves, 8. handles
As shown in the figure, vibration isolation rubber (4) respectively is arranged on the adapter shaft (2) with spacing sleeve (3), by hold-down nut (5) the vibration isolation rubber radial dimension is increased, tensioner at handrail interior (1), jam nut (6) is locking further, can prevent that hold-down nut (5) from getting loose automatically, guarantee handrail the functional reliability of (1), handle (8) is connected with adapter shaft (2) by handgrip adapter sleeve (7).
Adopt walker tractor vibration damping handrail described in the utility model can be effectively by body by handrail the oscillation frequency that passes to handle, amplitude and acceleration/accel improve tractor driver's service conditions greatly.
Claims (1)
1, a kind of walker tractor vibration damping handrail handle is by handle, handrail is waiting composition, it is characterized in that handle (8) and handrail being connected by an adapter shaft (2) between (1), coupling spindle (2) is with vibration isolation rubber (4) alternately and fixes by hold-down nut (5), jam nut (6) with spacing sleeve (3).
