Abstract
The utility model discloses a spring braking totally-closed wet-type parking brake which comprises a braking sleeve, a cylinder body and an end cover. The braking sleeve, the cylinder body and the end cover are sequentially connected through bolts. A spline housing, a connecting shaft sleeve, an outer friction piece and an inner friction piece are installed in the braking sleeve, the spline housing is connected with the outer friction piece, and the connecting shaft sleeve is connected with the inner friction piece. A piston and a guide shaft are installed in the cylinder body, a disc spring is arranged between the piston and the end cover, one end of the guide shaft penetrates the end cover, and an oil inlet is further formed in the wall of the cylinder body. After adopting the structure, the spring braking totally-closed wet-type parking brake is compact in structure, long in service life and large in braking torque, and the cooling oil leakage problem is solved.
Description
Technical field
The utility model discloses a kind of brake application by spring Wholly-enclosed wetting parking brake, belong to automobile brake technical field.
Background technology
At present, the auxiliary gear box projecting shaft axle head of the vehicle using under mine is generally all provided with caliper disc or shoe brake, although these two kinds of drg deceleration and stopping performancies are all more stable, but because auxiliary gear box projecting shaft diameter is subject to structural limitations, the spline being connected with inner attrition piece is easily impaired, service life is short, and above-mentioned existing drg also to have lock torque less, the problem of oil coolant seepage.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of brake application by spring Wholly-enclosed wetting parking brake, this brake structural compactness, and long service life, and lock torque is large, and solved the problem of oil coolant seepage.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of brake application by spring Wholly-enclosed wetting parking brake, comprises braking overcoat, cylinder body and end cap, and this braking overcoat, cylinder body and end cap are connected in turn by bolt; In described braking overcoat, spline housing, connecting bushing, outside friction disc and inner attrition piece are installed, wherein spline housing is connected with outside friction disc, and connecting bushing is connected with inner attrition piece; Piston and the axis of guide are installed in described cylinder body, between piston and described end cap, have dish spring, one end of this axis of guide, through described end cap, is also provided with oil inlet on described cylinder wall.
Further setting as such scheme: also there is ball-bearing casing between described spline housing and connecting bushing.
Adopt after said structure, the utility model compact conformation, long service life, and lock torque is large, and solved the problem of oil coolant seepage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Shown in Fig. 1, a kind of brake application by spring Wholly-enclosed wetting parking brake, comprises braking overcoat 1, cylinder body 2 and end cap 3, and this braking overcoat 1, cylinder body 2 and end cap 3 are connected in turn by bolt 13; Spline housing 4, connecting bushing 5, outside friction disc 6 and inner attrition piece 7 are installed in described braking overcoat 1, and wherein spline housing 4 is connected with outside friction disc 6, and connecting bushing 5 is connected with inner attrition piece 7; Piston 8 and the axis of guide 9 are installed in described cylinder body 2, between piston 8 and described end cap 3, have dish spring 10, one end of this axis of guide 9, through described end cap 3, is also provided with oil inlet 11 on described cylinder body 2 walls.Between described spline housing 4 and connecting bushing 5, also there is ball-bearing casing 12, be convenient to like this connecting bushing 5 and rotate.
When the utility model uses, the auxiliary gear box projecting shaft of vehicle inserts in connecting bushing 5, in the time of oil inlet 11 cut-in pressure oil, promotes piston 8 and moves right, and compact disc spring 10, throws off outside friction disc 6 and inner attrition piece 7, removes automobile brake.In the time that oil inlet 11 is connected fuel tank, dish spring 10 discharges, and piston 8 is moved to the left, and outside friction disc 6 and inner attrition piece 7 are compressed, and auxiliary gear box projecting shaft no longer rotates, in braking mode.
The utlity model has following characteristics:
1. because dish spring 10 is arranged between piston 8 and end cap 3, will reduce 25% than domestic other drg length directions, structure is compact.
2. because auxiliary gear box projecting shaft diameter is subject to structural limitations, be directly connected with inner attrition piece 7, spline is easily damaged, and has increased after connecting bushing 5, has strengthened the diameter of inner attrition piece 7 female spliness, has greatly strengthened spline joint intensity, has extended service life.
3. the utility model has larger lock torque, only needs to change the quantity of outside friction disc 6 and inner attrition piece 7, just can meet the brake request of 10 tons of following different vehicle of load-carrying under coal mine.
4. the utility model piston 8 has separated outside friction disc 6 and inner attrition piece 7 and dish spring 10, makes the oil coolant in the utility model be not easy seepage.
