Abstract
The invention discloses a kind of wheel hub pump oil mechanism, wheel hub including being rotationally connected with axle housing, Spindle nose cover is connected with the wheel hub, also include the drive block for being connected to axle housing end, it is connected to the helical oil groove of Spindle nose cover, and one end is connected to drive block, the spindle nose cover core of other end insertion helical oil groove, the spindle nose cover core leaves gap with helical oil groove, the helical oil groove inwall is provided with the screw thread opposite with wheel hub direction of rotation, and the oil duct that oil inlet is located in helical oil groove is additionally provided with the Spindle nose cover.In vehicle travel process, spindle nose cover core remains stationary state, helical oil groove rotates with hub assembly, relative motion between the screw thread and Spindle nose cover outer core of helical oil groove inwall produces extruding to conduction oil makes its flowing, and because conduction oil is more sticky, speed is slower, the cutting force of screw thread is bigger, pump oil speed is faster, it is not necessary to is additionally provided the energy, no operating cost.
Description
Technical field
The present invention relates to automotive field, and in particular to a kind of wheel hub pump oil mechanism.
Background technology
Automotive brake is divided into hub and the major class of dish-style two, is frictional, i.e., makes the vehicle in traveling by frictional force
Braking.Disc brake is open design, and caliper is rubbed from the both sides of brake disc, and caused heat is fast in friction process
Speed accumulation, when vehicle is continuously braked, and especially load-carrying vehicle is continuously braked in long ramp, brake disc temperature is gradually risen up to number
Hundred degrees Celsius, brake disc is set to cross Thermal cracking, brake(-holder) block ablation so that misfunctioning of brake, it is easy to road safety accident is caused, and
And when brake disc temperature exceedes the curing temperature of rubber for tire, tire is easy on fire cause fire incident.
Prior art generally sets air-vent on the disc brake rotor, is realized and radiated by air circulation；It is total well known, conduction oil
Radiating effect it is more preferable, but prior art installed on brake or wheel hub or axle housing pump oil mechanism exist power supply, fuel feeding, resist
Many problems such as shake, operating cost, therefore but disc brake has no successful any report always for oil cooling.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of wheel hub pump oil mechanism, can solve prior art in brake
Or pump oil mechanism is installed on wheel hub or axle housing and many problems be present, cause oil cooling but asking of can not implementing of disc brake
Topic.
The present invention is achieved through the following technical solutions：
A kind of wheel hub pump oil mechanism, including the wheel hub of axle housing is rotationally connected with, Spindle nose cover is connected with the wheel hub, is also wrapped
The drive block for being connected to axle housing end is included, is connected to the helical oil groove of Spindle nose cover, and one end is connected to drive block, the other end is inserted
Enter the spindle nose cover core of helical oil groove, the spindle nose cover core leaves gap with helical oil groove, and the helical oil groove inwall is provided with and wheel
The opposite screw thread in hub direction of rotation, the oil duct that oil inlet is located in helical oil groove is additionally provided with the Spindle nose cover.
The further scheme of the present invention is that the spindle nose cover core is provided with the cover core axle radially extended, the drive block
It is provided with the groove coordinated with cover core shaft clearance.
The further scheme of the present invention is that the spindle nose cover core is arranged at its openend into tubular, the cover core axle, its envelope
Closed end is connected with relief valve.
The further scheme of the present invention is that the outage of oil duct is communicated with the Spindle nose cover, is blocked by plug.
The present invention compared with prior art the advantages of be：
First, in vehicle travel process, spindle nose cover core remains stationary state, helical oil groove rotates with hub assembly, spiral oil
Relative motion between the screw thread and Spindle nose cover outer core of groove inwall produces extruding to conduction oil makes its flowing, and due to heat conduction
Oil is more sticky, and speed is slower, and the cutting force of screw thread is bigger, and pump oil speed is faster, it is not necessary to be additionally provided the energy, no operation into
This；
2nd, the gap of cover core axle and groove, which coordinates, has certain buffering capacity, it is ensured that even if hub assembly is with vehicle
Generation of jolting, which loosens, does not interfere with pump oil effect yet；
3rd, relief valve is used for the pressure release in pump oil hypertonia；
4th, need first to remove plug when opening Spindle nose cover, with the rotation of hub assembly, conduction oil is gradually discharged.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.

And one end is connected to drive block 5, the spindle nose cover core 4 of other end insertion helical oil groove 38, the spindle nose cover core 4 and helical oil groove
38 leave gap, and the inwall of helical oil groove 38 is provided with the screw thread opposite with wheel hub direction of rotation, is additionally provided with the Spindle nose cover 2
Oil inlet is located at the oil duct 40 in helical oil groove 38.The drive block 5 is vertically extending from center pillar and from center pillar both ends to side
Pin, formed in the middle part of center pillar to the vertically extending projection of opposite side, the pin, which is fixedly connected on, is symmetricly set on axle housing 47
The slot 41 of end, the projection are provided with groove 49, and the spindle nose cover core 4 is provided with and radially extended into tubular, its openend
Cover core axle 36, blind end is connected with relief valve 3, and the cover core axle 36 coordinates with the gap of groove 49；The Spindle nose cover 2 is provided with
The outage of oil duct 40 is connected, is blocked by plug 1.
The oil inlet of oil duct 40 and oil-out are respectively communicated with circulating oil path, in vehicle travel process, helical oil groove 38
Conduction oil is pumped into the oil inlet of oil duct 40 by the relative motion with spindle nose cover core 4, enters circulating oil path from oil-out.
