Abstract
The invention relates to an automatic air supplying pump for a wheel for automatically supplying air to a tyre leaking air in the running process of a vehicle. A sliding hole is disposed in an axis of an axle, and a slide-bar is in movable connection with the sliding hole through a guide key. A working piston and a compression spring are arranged in a working cylinder, and a control piston is arranged in a control cylinder. A pump body is connected with a hub; the right end face of an eccentric shaft is in movable connection with the left end face of the control piston; and the axial surface of an eccentric shaft is in movable connection with the lower end face of the working piston. In use, the working piston in the working cylinder reciprocates up and down under the combined action of the eccentric shaft and the compression spring and presses air into the tyre, while the pressure in the control cylinder is increased along with the increase of the pressure in the working cylinder, when the pressure reaches the rated pressure, the control piston gradually pushes the eccentric shaft leftwards until the axial surface of the eccentric shaft is out of contact with the lower end face of the working piston and the working piston stops working.
Description
Technical field
The present invention relates to the automatic air supply device that a kind of tire is used, especially can in the vehicle ' process, carry out the automatic air supplying pump for wheel of gas make-up automatically to the tire that produces gas leakage.
Background technology
At present, the aerating if the gas leakage of known vehicle tire just can only be stopped, and can't in the vehicle ' process, carry out gas make-up to the tire that produces gas leakage automatically.
Summary of the invention
If in order to overcome just can only the stop deficiency of aerating of existing vehicle tire gas leakage, the invention provides a kind of automatic air supplying pump for wheel, this automatic air supplying pump for wheel can carry out gas make-up to the tire that produces gas leakage automatically in the vehicle ' process.
The technical solution adopted for the present invention to solve the technical problems is: the present invention includes gas piping, the pump housing, wheel hub, air inlet valve, bearing, axletree, working piston, eccentric shaft, seal ring, valve, working cylinder, ventilation flue, control plunger, control cylinder, slide-bar, slide opening, lead key and compression spring.Wheel hub is connected on the axletree by bearing, offers slide opening in the axle center of axletree, is sequentially set with compression spring and slide-bar in slide opening from left to right, and slide-bar connects by lead key is moving with slide opening, and the right-hand member spindle nose of slide-bar is set to eccentric shaft.On the pump housing, offer working cylinder and control cylinder, working cylinder is perpendicular to control cylinder, air inlet valve is arranged on the pump housing and with the bottom of working cylinder and is communicated with, working cylinder is communicated with by the ventilation flue again with the bottom of control cylinder simultaneously, be sequentially set with working piston and compression spring in working cylinder from bottom to up, working piston is provided with seal ring, and valve is connected the upper port of working cylinder, be provided with control plunger in control cylinder, control plunger is provided with seal ring.The pump housing is connected with wheel hub, and makes control cylinder and slide opening be in same axis, and the right side of eccentric shaft connects with the left side of control plunger is moving, and the axial plane of eccentric shaft connects with the lower surface of working piston is moving, and valve is communicated with the air inlet valve of tire by gas piping.In the use, along with the relative motion between axletree and wheel hub, working piston in the working cylinder just moves back and forth up and down under the combined action of eccentric shaft and compression spring, and therefore gas is sucked the working cylinder from air inlet valve, be pressed in the tire by valve and gas piping again, and the air pressure in the control cylinder also increases along with the increase of air pressure in the working cylinder, when air pressure reaches rated pressure, control plunger in the control cylinder will be gradually to left translation eccentric shaft and slide-bar, and disengage up to the axial plane of eccentric shaft and the lower surface of working piston, till working piston quits work.
The invention has the beneficial effects as follows, can in the vehicle ' process, carry out gas make-up to the tire that produces gas leakage automatically.

The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 5, wheel hub 3 is connected on the axletree 6 by bearing 5, offer slide opening 16 in the axle center of axletree 6, in slide opening 16, be sequentially set with compression spring and slide-bar 15 from left to right, slide-bar 15 moves by lead key 17 with slide opening 16 and connects, and the right-hand member spindle nose of slide-bar 15 is set to eccentric shaft 8.On the pump housing 2, offer working cylinder 11 and control cylinder 14, working cylinder 11 is perpendicular to control cylinder 14, air inlet valve 4 is arranged on the pump housing 2 and with the bottom of working cylinder 11 and is communicated with, working cylinder 11 is communicated with by ventilation flue 12 again with the bottom of control cylinder 14 simultaneously, in working cylinder 11, be sequentially set with working piston 7 and compression spring from bottom to up, working piston 7 is provided with seal ring 9, valve 10 is connected the upper port of working cylinder 11, be provided with control plunger 13 in control cylinder 14, control plunger 13 is provided with seal ring 9.The pump housing 2 is connected with wheel hub 3, and make control cylinder 14 and slide opening 16 be in same axis, the right side of eccentric shaft 8 connects with the left side of control plunger 13 is moving, and the axial plane of eccentric shaft 8 connects with the lower surface of working piston 7 is moving, and valve 10 is communicated with the air inlet valve of tire by gas piping 1.
At Fig. 4, among Fig. 6, relative motion along with 3 of axletree 6 and wheel hubs, working piston 7 in the working cylinder 11 just moves back and forth up and down under the combined action of eccentric shaft 8 and compression spring, and therefore gas is sucked the working cylinder 11 from air inlet valve 4, be pressed in the tire by valve 10 and gas piping 1 again, and the air pressure in the control cylinder 14 also increases along with the increase of air pressure in the working cylinder 11, when air pressure reaches rated pressure, control plunger 13 in the control cylinder 14 will be gradually to left translation eccentric shaft 8 and slide-bar 15, and disengage up to the axial plane of eccentric shaft 8 and the lower surface of working piston 7, till working piston 7 quits work.
