The application of the tractor saddle assembly of the present disclosure to a semi-tractor will now be described.

As shown in fig. 1 to 3, the tractor saddle assembly includes: the saddle comprises a saddle 1, a saddle support 2, a saddle sliding support frame 3, a saddle pin 5, a slideway, a saddle adjusting mechanism, a bearing weight measuring mechanism and a control mechanism (not shown in the figure), wherein the saddle 1 is installed on the saddle support 2 through the saddle pin 5, the saddle support 2 is fixed on the saddle sliding support frame 3 through a bolt, the saddle sliding support frame 3 is arranged on the slideway in a sliding manner, the slideway is used for being fixedly installed on a frame, and the saddle adjusting mechanism is used for driving the saddle sliding support frame 3 to slide on the slideway; the bearing weight measuring mechanism is used for measuring the bearing weight of the saddle 1; the control mechanism is used to control the saddle adjustment mechanism in accordance with the load weight of the saddle 1 to adjust the longitudinal position of the saddle 1 relative to the vehicle frame.

As shown in fig. 1 to 3, the control mechanism controls the saddle adjusting mechanism to adjust the longitudinal position of the saddle 1 relative to the frame according to the load weight of the saddle 1 measured by the load weight measuring mechanism, so that the automatic adjustment of the longitudinal position of the saddle 1 on the frame is realized, the load bearing quality of each bridge of the tractor is reasonably distributed, and the purpose of improving the vehicle handling performance is achieved.

As an implementation way of the saddle sliding support frame 3 being slidably disposed on the slide way, in some embodiments, as shown in fig. 1 and fig. 2, the slide way includes a first slide way side surrounding piece 7 and a second slide way side surrounding piece 9, the saddle sliding support frame 3 is embedded between the first slide way side surrounding piece 7 and the second slide way side surrounding piece 9, and as shown in fig. 2, a plurality of rotating wheels 10 supporting the saddle sliding support frame 3 are disposed between the first slide way side surrounding piece 7 and the second slide way side surrounding piece 9. The arrangement of the plurality of rotating wheels 10 realizes effective support of the saddle sliding support frame 3 by the slideway, and the practicability is strong.

In order to increase the contact amount between the saddle sliding support 3 and the rotating wheel 10, in some embodiments, as shown in fig. 2, the cross section of the contact portion between the saddle sliding support 3 and the rotating wheel 10 is an inverted T shape, and the bottom surface of the contact portion between the saddle sliding support 3 and the rotating wheel 10 is a plane. The saddle sliding support frame 3 with the contact part in the inverted T shape can be well contacted with the rotating wheel 10, and the longitudinal positioning of the saddle sliding support frame 3 by the first slide side wall part 7 and the second slide side wall part 9 is realized, so that the falling is avoided.

In order that the load-bearing weight measuring mechanism can not bear the load-bearing weight from the saddle at all times during the running process of the vehicle, in some embodiments, the load-bearing weight measuring mechanism is arranged on one longitudinal side in the slideway, namely on the front side or the rear side in the longitudinal direction in the slideway, so that when the load-bearing weight of the saddle 1 needs to be detected, the saddle adjusting mechanism adjusts the saddle 1 to the position of the load-bearing weight measuring mechanism on one side for measurement; after the measurement is finished, the saddle adjusting mechanism adjusts the saddle 1 to be far away from the bearing weight measuring mechanism, and the influence of impact on the precision and the service life of the bearing weight measuring mechanism is effectively avoided.

And the supporting wheel has the same structure as the rotating wheel 10, so that the processing and the installation are convenient.

It should be noted that, because the tractor saddle assembly is a bilaterally symmetric structure, the support wheels are paired, and the support wheel supporting the saddle sliding support frame 3 alone does not mean that a single support wheel supports the saddle sliding support frame 3, but means that the support wheel is supported separately relative to the rotating wheel 10, i.e., one or two or even more pairs of support wheels mounted with the pin force sensor 4 support the saddle sliding support frame 3.

In some other embodiments, the load weight measuring mechanism is a weighing scale built into the saddle 1 or saddle sliding support 3.

As to how to lock the longitudinal position of saddle 1 with respect to the vehicle frame, in some embodiments this can be achieved by means of telescopic cylinders 15, or by providing a separate locking mechanism, the function of which is to fix the position of saddle 1 after saddle 1 has been moved to the position designated by the control mechanism, and in some embodiments the tractor saddle assembly further comprises: a locking mechanism for locking the longitudinal position of the saddle 1 with respect to the frame.

When the contact position of the limiting pin 6 and the cam 13 is changed from a low point to a high point, the limiting pin 6 moves towards the side wall parts of the slide ways on the two sides respectively and is matched with the limiting holes 8 arranged on the side wall parts of the slide ways to play a limiting role.

In some embodiments, the limit pin 6 has a variable cross-section structure, the locking mechanism includes a return spring 12, the mounting sleeve is disposed on the limit pin 6 and is used for automatically returning the limit pin 6 to the cam 13, the return spring 12 is mounted between the limit pin 6 and the limit pin support 11 due to the limit pin 6 having the variable cross-section structure, when the contact position of the limit pin 6 and the cam 13 changes from a high point to a low point, the automatic return of the limit pin 6 to the direction of the rotation center of the cam 13 can be achieved, the position of the saddle sliding support frame 3 is no longer limited by the limit pin 6, and in some embodiments, the rotation of the cam 13 is driven by an electric motor or a hydraulic motor.

For the implementation of the control mechanism, in some embodiments, the control mechanism comprises a signal processing module and a control module; in a load recognition mode, the signal processing module is used for receiving artificial input signals and sending control signals to the control module, the input end of the control module is connected with the output end of the signal processing module, the control module is used for receiving the control signals and controlling the saddle adjusting mechanism to drive the saddle sliding support frame 3 to the load weight measuring mechanism, namely, the control module receives the control signals sent by the signal processing module and controls the telescopic oil cylinder 15 to change and fix the displacement, so that the saddle sliding support frame 3 is only supported by two pairs of supporting wheels provided with the pin shaft force sensor 4, and the pin shaft force sensor 4 measures the load weight on the saddle 1; in the automatic adjustment mode, the signal processing module is used for sending a control signal to the control module according to the bearing weight measured by the bearing weight measuring mechanism, the control module is used for receiving the control signal and controlling the saddle adjusting mechanism to drive the saddle sliding support frame 3 to a preset position corresponding to the bearing weight, namely the control module controls the telescopic oil cylinder 15 to change the fixed displacement, so that the saddle sliding support frame 3 leaves the two pairs of support wheels to be supported to the preset position corresponding to the bearing weight. In order to ensure effective matching between the limiting pin 6 and the limiting hole 8, the extension amount of the telescopic oil cylinder 15 is divided into a plurality of gears, each gear corresponds to a bearing weight range, and the optimal matching relation between the gear of the telescopic oil cylinder in the control mechanism and the bearing weight range of the saddle 1 is obtained through a whole vehicle operation stability test.
