Description
Technical Field
The utility model relates to the technical field of mowing devices, in particular to a walking mechanism of a mowing vehicle with a steering shaft.
Background
The turning of the traveling mechanisms of most of the existing mowing vehicles is mainly divided into two types, when the mowing vehicle with a header behind a traditional large tractor turns, a high-power hydraulic oil cylinder is adopted for turning, a driving parallel four-bar mechanism is adopted, and then two tires are driven to simultaneously turn, so that the requirement on the turning driving force is high; the small-size car of mowing all is the four-wheel drive mostly, relies on the differential to turn to, turns to the consumed power huge like this, because it is the pure slip during the turning to and turns to, and tire and meadow produce sliding friction, all have certain damage to tire and meadow, and the whole rigidity requirement of chassis running gear to the car of mowing is very high moreover. In order to solve the existing problems, the mowing vehicle travelling mechanism with the steering shaft is provided, the steering shaft is embedded in the mowing vehicle travelling mechanism in a certain mode, receives power from a steering driving motor, and controls the steering shaft to drive the travelling mechanism to steer when the mowing vehicle needs to steer, so that a transmission link between the steering shaft and the travelling mechanism is simplified, the steering force arm is shortened, and the steering tire can realize accurate steering according to requirements.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a mower travelling mechanism with a steering shaft.
The technical purpose of the utility model is realized by the following technical scheme:
the utility model provides a take lawn mower walking mechanism of steering spindle, includes upper end steering spindle, walking bearing cup, walking axle, round nut, end cover, wheel mounting flange and lower extreme steering spindle, upper end steering spindle and lower extreme steering spindle are fixed mounting respectively at the upper and lower both ends of walking bearing cup, upper end steering spindle and lower extreme steering spindle pass through combination bearing fixed mounting on the automobile body of lawn mower, the one end of walking axle is passed through walking bearing and is installed on walking bearing cup to lock through lock washer and round nut, the end cover passes through bolt fixed mounting on walking bearing cup to the lid closes in walking bearing's the outside, wheel mounting flange installs on walking axle to be connected with the transmission between the walking axle.
Furthermore, the walking bearing is a double-row angular contact ball bearing, and the model number of the walking bearing is DAC 4007537.
Further, the upper end steering shaft and the lower end steering shaft are respectively and fixedly installed at the upper end and the lower end of the traveling bearing cup through screws, and the screws are installed by 6M 6.
Furthermore, the wheel mounting flange is fixedly mounted on the walking shaft through a duck tongue type locking gasket and a locking nut.
Furthermore, the wheel mounting flange is in transmission connection with the walking shaft through a key, and the key is a flat key or a spline.
In conclusion, the utility model has the following beneficial effects:
(1) the transverse transmission size of the traveling mechanism of the mowing vehicle can be simplified, so that the transmission is compact and efficient, and the reliability and the transmission efficiency of the mechanism are improved;
(2) the steering shaft is connected to the travelling mechanism through a screw, so that the travelling mechanism can be steered effectively, the steering shaft is connected right above the travelling mechanism and is close to the center of a tire, the steering force arm is small, and steering is easier; in addition, the steering shaft and the travelling mechanism are not made into a steering gear integrated type, so that the whole travelling mechanism can be maintained more simply and conveniently;
(3) the running mechanism uses a single double-row angular contact ball bearing to replace the traditional paired tapered roller bearings, so that the transmission becomes simpler, the reliability of the mechanism is greatly improved, in addition, the application of the single bearing can also more conveniently locate the faults occurring later, the part replacement is simpler and more convenient, and the maintenance performance of the whole mechanism is improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-2, a mower traveling mechanism with a steering shaft comprises an upper end steering shaft 1, a traveling bearing cup 2, a traveling shaft 3, a round nut 6, an end cover 7, a wheel mounting flange 8 and a lower end steering shaft 12, wherein the upper end steering shaft 1 and the lower end steering shaft 12 are respectively and fixedly mounted at the upper end and the lower end of the traveling bearing cup 2, the upper end steering shaft 1 and the lower end steering shaft 12 are fixedly mounted on a mower body of the mower through a combined bearing, one end of the traveling shaft 3 is mounted on the traveling bearing cup 2 through the traveling bearing 4 and is locked through a stop washer 5 and the round nut 6, the end cover 7 is fixedly mounted on the traveling bearing cup 2 through a bolt and covers the outer side of the traveling bearing 4, and the wheel mounting flange 8 is mounted on the traveling shaft 3 and is in transmission connection with the traveling shaft 3.
Further, the walking bearing 4 is a double-row angular contact ball bearing, and the model number of the walking bearing is DAC 4007537.
Further, the upper end steering shaft 1 and the lower end steering shaft 12 are respectively and fixedly mounted at the upper end and the lower end of the traveling bearing cup 2 through screws, and the screws are mounted by 6M 6.
Further, the wheel mounting flange 8 is fixedly mounted on the walking shaft 3 through a duck tongue type locking washer 10 and a locking nut 11.
